how to access local full node from other machine...

In an effort to learn about and support the neetwork, I have setup a full node running bitcoin core on a dedicated linux box. It's been running smoothly for about a month after the blockchain dl and I smile a little every time I login to check logs and diskspace and all the little sysadmin tasks.
I would like to run a wallet gui client on my daily box that accesses the bitcoin box in a client/server sort of way.
Can bitcoin core do this? If not, is there a wallet (windows) that will provide a full gui while using the bitcoin core daemon running on my linux box?

Fun with Dynamic DNS services and bitcoind

I realize that bitcoind has this capability built in, but thought it might be fun to configure it manually. As some background, most people look at their network and they have some address like 192.168.1.105. That is a private network address. Sites like WhatIsMyIpAddress.com will tell you what your EXTERNAL IP address is. When your running a bitcoin node, people will connect to your external IP.
Problem is... your ISP may cycle that IP address every week or so. bitcoind has a nice feature baked in called discover which will do the work of guessing your external IP as it changes. But if you are doing anything where you need to expose your RPC API externally (*danger*) then it would be nice to have some FQDN to go after to do the IP translation.
Originally, I had always solved this by exposing my node as an onion node. Since onion nodes traverse NATs and firewalls fairly effortlessly this was an easy option. But previously I had played around with Dynamic DNS service. I've used noip.com but there are likely dozens of services out there that will get the job done.
Once you have enabled a NoIP hostname, you can name it in your bitcoin.conf using the externalip=coolbtcnode.ddns.net. Then, assuming you setup all the RPC auth and port forwarding, you could access your node via RPC at coolbtcnode.ddns.net
As I said... it's a redundancy, since discover=1 does most of this for you, but still thought someone might enjoy the tip.

Epic Cash AMA Recap with CryptoDiffer Community

CryptoDiffer team Hello, everyone! We are glad to meet here: Max Freeman (@maxfreeman4), Project Lead at Epic Cash Yoga Dude (@Yogadude), PR&Marketing at Epic Cash Xenolink (@Xenolink), Advisor at Epic Cash
Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here!
Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here!
Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us!
CryptoDiffer team Let`s start from the first introduction question: Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash?
Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a
Xenolink Advisor at Epic Cash
From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.
CryptoDiffer team
Great, thank you for your answers, we now can move to community questions part!
Cryptodiffer Community
You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.
Cryptodiffer Community
To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.
Cryptodiffer Community
Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.
Cryptodiffer Community
$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.
Cryptodiffer Community
What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.
Cryptodiffer Community
EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability
Cryptodiffer Community
Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.
Cryptodiffer Community
I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique
Cryptodiffer Community
Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.
Cryptodiffer Community
If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.
Epic Cash will have its OWN Celebrities
Cryptodiffer Community
How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.
Cryptodiffer Community
what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.
Cryptodiffer Community
Q1 : What are your major goals to archive in the next 3–4 years?
Q2 : What are your plans to expand and gain more adoption?
Yoga Dude Pr&Marketing at Epic Cash
Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.
Cryptodiffer Community
It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.
Epic Cash is More than Money and its for Everyone.
Cryptodiffer Community
Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

  1. You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
  2. How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash
Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well.

Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.
Everyone with skin in the game gets the benefit of advancing the cause.
Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content —
https://www.youtube.com/watch?v=XtAVEqKGgqY
a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this
Cryptodiffer Community
I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166
Max Freeman Project Lead at Epic Cash
Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project.

Smelting some Anonymous Electrum.

So with the newest I2P client being several years old, I thought it might be a good idea to drum up some interest in an I2P version of the popular Electrum bitcoin client. Just as this works well with TOR due to its client-server methodology, I think it would work great with I2P. I am willing to run an I2P Electrum node if we can make it happen, and can TS the product itself, Linux(deb) or Windows either works. I have already posted a companion post in Electrum as well. With everything going on, I feel a stable and usable Bitcoin client for I2P would be very beneficial not just for I2P but for the community. Let's see what we can do!

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

A slightly overboard response to my threat model.

For what I hope are obvious reasons, I don't want, and probably will never post my threat model publicly online. However, regardless of that, what I'm sure you will extrapolate from this post is that I live my life, digitally in particular, with a fairly high level threat model. This is not because I'm some super sophisticated criminal mastermind, but rather, I am at this level because I genuinely love playing around with this stuff. And I just happen to understand the importance of privacy and just how vital it is to a truly healthy society. I would like to extend a thanks to ProgressiveArchitect for the sharing of the knowledge they have done on this subreddit, /privacytoolsio, and the like. We may have never interacted, but nevertheless, your input into this community is truly interesting and extremely informative and educating. I'm sure those of you familiar with PA's setup will be able to draw some parallels with mine and their's.
Thank you.
I hope you all enjoy reading this write up.
I run Qubes OS on a Lenovo ThinkPad X230 laptop. Specs for it are as following: - i7-3520M - 16GB RAM - 1TB Samsung 860 Evo SSD - Qualcomm Atheros AR9285 wireless card
Additionally, I used a Raspberry Pi Model 3B+ and a Pomono SPI clip to replace the stock BIOS firmware with coreboot+me_cleaner. This wasn't done out of any "real" concern for the Intel ME (though of course proprietary black-boxes like it should be avoided at all costs and not trusted), but rather for open source enthusiasm and for increased security and faster boot times than what the stock BIOS firmware allows for. On that note about the ME, I don't believe the conspiracy theories that claim that it is a state-sponsored attack method for surveillance. I believe that Intel had good intentions for improving the lives of IT professionals who need to manage hundreds, if not thousands of remote machines. However, it has proven time and time again to be insecure, and I don't need the remote management and the "features" that it provides on my machines.
In Qubes, I use a combination of AppVMs and StandaloneVMs for a variety of different purposes. All VMs use PVH over HVM, except for the Mirage Unikernel Firewall, which uses PV, and the sys-net and sys-usb StandaloneVMs which have to use HVM because of PCI device passthrough. Right now most of my VMs are AppVMs, but for maintenance and compartmentalization reasons, I am considering moving more towards StandaloneVMs, despite the increase in disk space and bandwidth usage for updates.
General route of from Qubes to the Internet for anonymous browsing, general private browsing, accessing Uni services, and Uni-related anonymous browsing respectively: 1. Qubes->sys-mirage-firewall->sys-vpn-wg->sys-corridor->sys-whonix->whonix-ws-15-dvm to the internet. 2. Qubes->sys-mirage-firewall->sys-vpn-wg to the Internet. 3. Qubes->sys-mirage-firewall->uni-vpn-wg to the Internet. 4. Qubes->sys-mirage-firewall->uni-vpn-wg->uni-corridor->uni-whonix->uni-anon-research to the Internet.

(Note: the VPN name is substituted in the "vpn" above. I had to remove it to comply with this subreddit's rules. It is easy to identify what VPN it is as it randomly generates a long numaric string and has fantastic support for WireGuard.)

Web Browsers: - Tor Browser (primary) in a disposable Whonix VM. - Firefox (secondary) with the about:config changes listed on privacytools.io and the following extensions: Cookies AutoDelete, Decentraleyes, HTTPS Everywhere, uBlock Origin (advance user, all third party content blocked and JavaScript disabled), and Vim Vixen. Used in my personal AppVM. - Ungoogled Chromium (Uni only) with standard uBlock Origin and cVim. Used only for Uni-related access in my uni-campus and uni-home AppVMs.
Search Engine: SearX, Startpage, and DuckDuckGo.
Password Manager: KeePassXC.
Office: LibreOffice.
Notes: Standard Notes.
Messaging: Signal Desktop.
Media Playback: mpv.
Emails: I access my personal email within my personal Qubes domain and my Uni email using my Uni Qubes domains. My emails are downloaded to a local repository using isync, send using msmtp, and read using neomutt with html emails converted to plain text using w3m. Emails are sent in plain text too. All of the attachments in the emails (PDFs mostly) are automatically opened in DisposableVMs.
My personal Posteo email account has incoming encryption setup. This means that I emailed my public GPG key to an address correlated to my actual Posteo email address so that all email that I receive is encrypted with my public key and can only be decrypted using my private key. So even if my emails were intercepted and/or my account broken into, the contents of them are safe since they are encrypted as soon as they hit Posteo's servers.
I have setup a number of Posteo aliases that are completely segregated from the email I used to register my account. One of those is considered my "professional" email for my current job. I have another couple aliases, one dedicated for 33mail and another dedicated for Abine Blur. I make use of 33mail alias addresses for catch-all email addresses for registering for accounts that need to be under a username associated with my name anyways. This is for purposes like putting different compartmentalized, but still related emails to put onto my Resume. I use a different alias for each Resume I put out online. That way, when that information gets sold, traded, etc., I can easily trace it back to who sold the information. For example, if I applied for a job online that required me to go through the process of registering an account through a third-party, say 'xyz Inc', the address I would register that account with would be [email protected], or something along those lines. Abine Blur is used much in the same manner but for accounts that don't need to be associated with my real name in any way, say online shopping on Amazon that I do under an many aliases, then ship to various address that I don't live at, but that I can visit with no problems. I use a different Blur address with each service like with 33mail for the same reasoning shown above.
The passwords for the accounts are encrypted and stored locally in each of the domains, however, my private key is stored in my vault domain, so even if an adversary were to compromise the domains, they wouldn't be able to steal my private key without exploiting the hypervisor. They would only be able to wait for me to authorize the usage of my private key in that domain, and even then, it could only be used to decrypt files. That is a concern that they can use my private key to decrypt messages, but they wouldn't be able to steal the key. With my personal email, the emails would also be encrypted locally anyway so they wouldn't be able to read them. My Uni email, in contrast, uses Outlook unfortunately, so there isn't any option to enable incoming encryption, and even if it was, I'm not sure how private it would be anyways.
For those looking for an in depth list of all my VMs, with explanations for the more obscure ones, I have listed them below. I have got a lot of templates, hence why I am considering moving over to StandaloneVMs, but as of right now:

Templates:

StandaloneVMs:

AppVMs:

Phone: Motorola Moto G5s running Lineage OS 16.0 Pie no G-Apps or micro-G with the following Apps: - AdAway: Open Source hosts file-based ad blocker. (Requires root.) - AFWall+: Linux iptables front end. (Requires root.) - Amaze: File manager. - andOPT: 2FA app. I like it since it can export the entries to an AES encrypted file. - AntennaPod: Podcast manager. - AnySoftKeyboard - Simple Calendar - Simple Contacts Pro - DAVx5: CalDav syncronization with my calendar on my Posteo email account. - F-Droid - Fennec F-Droid: Web Browser. Has the same Firefox addons like on Qubes minus Vim Vixen. I used the app Privacy Settings to configure the about:config. - KeePassDX: Password manager. - KISS launcher - Magisk Manager - NewPipe: YouTube app replacement. - S.Notes: Standard Notes. - OsmAnd~: Maps and navigation. - Red Moon: Blue light filter. - SELinuxModeChanger: Exactly as it sounds. (Requires root.) - Shelter: Work profile manager. - Signal: Messaging. - Vinyl Music Player: Music player. - WireGuard: VPN protocol frontend. Is configured to use my VPN account. Is setup as an always-on and connected VPN.
As mentioned, I use Shelter to manage my work profile. In it I isolate the following apps: - Clover: *chan browser. - Orbot: For routing apps through Tor. Is setup as an always-on and connected VPN. - RedReader: Reddit client. - Tor Browser
Over the last several years, I have started using my phone less and less and taking advantage of less of what it has got to offer. I don't check email on my device. I have no real need to browse the Internet on it outside of watching videos using NewPipe, browsing Reddit, and various *chan boards.
On the Smart Phone side of things, I am considering purchasing an older used iPhone SE or 6S for use with MySudo when outside of my home as well as an iPod Touch for use on WiFi only for use inside my home. The iPhone would be kept inside of a faraday bag when I am at home and not using it. It would also be kept in the faraday bag whenever at home to avoid associating that device with my home address. The iPod Touch would be used for MySudo calls instead.
Future outlook and plan for my privacy and security:
To avoid as much deanonymisation of my privacy as possible, I'm only going to specify enough so that anyone reading this can get the jist of my situation in life. I am quite young (age 16 to 25) and I started along this privacy journey when I was even younger. I was never a very heavy social media user, however I did have an online presence if you looked hard enough. My name fortunately is a very common and short name, so that does help to bury information that I was not able to remove further in the vast trenches that is the Internet.
On the digital side of things, I mentioned that I have a dedicated Crypto AppVM for handling crypto currency transactions using Bisq. I have setup a dedicated bank account that I have periodically been transferring money into so that I can trade crypto. Unfortunately, I do not live in the US, so being able to effectively start trades with others is more difficult. I also do not have access to a credit card masking account like privacy.com (that I absolutely would use given the ability). I plan on getting an anonymous VPS to host my own Tor exit node for better speeds and to mitigate the possibility of malicious exit nodes. The country I live in has been a proponent of absolute dragnet surveillance on all activities occurring online and in real life, though the former is far more visible on this subreddit. I will be using crypto with cleaned Bitcoin (as seen with ProgressiveArchitect's setup) for purchasing my VPN service, etc.
With future hardware, to replace my aging laptop, I am very hopeful for Xen, then eventually Qubes OS getting ported to Power9. When that happens I'll be getting a Raptor Computing Blackbird as a desktop. Maybe in the future I'll get a Purism Librem laptop, but for now my corebooted X230 works perfectly for my use cases. On that note, I have successfully build the Heads firmware for the X230 and I was able to get the minimal 4MB image flashed on my laptop. I did revert it back to my coreboot setup after playing around a little with it, and unfortunately I haven't had time since to do a full, complete flash of it.
On the physical/real life side of things, I plan on making use of various Trusts in order to hold assets, say to keep my name from being immediately visible on the title of my car. As of right now I am fortunate enough to have the title of my car under the name of someone who I trust. Unless I am legally required, and where there are immediate and absolute consequences, I use fake names in real life. With Uni, I am enrolled under my real name and address. This is a requirement and it is verified, so there is nothing that I can realistically do about it. As for other services, I plan on setting up a personal mailbox (PMB), etc if possible to use as a real, physical address that is associated with my real name and that is used for things like Government issued ID. In the future when I move again, I plan on renting a place in cash to try and keep my name dissociated with my real address. For those looking for reasoning on why one would want to do that, please read How to be Invisible by J.J. Luna. It's truly the Bible of physical privacy.
At this stage I am just going off on a ramble, so I should cut it short here.
I have just started and I live for this shit.

[Lightning] I didn't believe it until I saw it

Moderately long post, tl;dr at the bottom.
I've seen lightning transaction gifs and videos over and over. Today, I decided to fire up a lightning node on my laptop and give it a shot.
I followed this walk-through for mac (I adapted it to Arch Linux) for setting up Bitcoin TestNet Node with Eclair Lightning (it's practically the same as Mac, except for the installation process). Running on Arch caused the problem of accidentally installing the latest dev version of Bitcoin Core (AUR:bitcoin-git) - also had some compilation issues because upstream moved some files and this hadn't been updated in the PKGBUILD.
The latest dev version of Bitcoin Core included the SegWit address generation by default, which was very nice, didn't have any bugs using it in the brief period I used it.
After a couple of hours of syncing the TestNet blocks on my laptop, I started up Eclair and got Eclair and Bitcoin Core connected (had to use bitcoin-qt --deprecatedrpc=addwitnessaddressbecuase Eclair calls a soon-to-be deprecated function), sent myself some tBTC, and started opening up channels. Once I had about 3 channels open, I went to everyone's favorite online coffee shop and rewarded myself with some imaginary coffee.
My mind was absolutely blown at how fast the transaction went through and how insanely low the fees were (10 sat).
I went to test a transaction with a couple more hops, bought myself an imaginary 100eur Steam voucher, paid 100 sat in fees, near instant transaction (my Eclair client took a couple seconds to find a route to bitrefill)
Lightning truly is an incredible addition to Bitcoin, big things are coming.
tl;dr - Saw a couple lightning transaction videos and gifs, didn't really sink in how amazing this really is, decided to give it a shot on linux, mind=blown
Edit: I've done a little further testing and noticed that Eclair doesn't warn you if you're opening a duplicate channel (open a second channel with the same node)

TOP 3 Anonymous Cryptocurrencies

TOP 3 Anonymous Cryptocurrencies
Last year Bitfury’s multidisciplinary Blockchain specialists announced the possibility of revealing the identities of more than 16% of all owners of Bitcoin addresses. Several years ago, a team of CryptoLux developers, having conducted a study of transaction privacy on the Bitcoin network, concluded that 60% of all addresses can be deanonymized. Summarizing all this, it’s worth highlighting three existing methods that can successfully deanonymize private transactions.

Clustering

The easiest way to cluster (link Bitcoin addresses) is by analyzing transactional networks. In other words, this is a method that allows finding several inputs combined in one transaction. The second clustering method is “distribution analysis”. It allows calculation the percentage of cryptocurrency at the certain address that comes from another specific address and it becomes clear whether these addresses are connected by one direct transaction or a chain of transactions or not.

Graph analysis

It consists of quantitative and temporal analyzes. Quantitative analysis studies not certain transactions, but amounts. Time analysis tracks specific periods.

Memory Pool Method

When a transaction is made through the user’s wallet, the input nodes send information about the transaction to the Blockchain network. The purpose of this method is to identify the set of input nodes through the wallet and the user. In this case, the IP address of the client can be associated with its transactions. There are certain private cryptocurrency-leaders which are popular and trusted among users. Using one feature-privacy, they have different ways of functioning.

Basic principles of work: anonymous cryptocurrencies (Monero, Dash, Zcash)

Monero

The platform focuses on privacy and decentralization. The coin uses three levels of protection:
• Ring signatures, that hide the origin of the sender by mixing the user’s address with the addresses of other group members. • Ring confidential transactions, which hide the amount of the transaction. • Stealth addresses, that allow a user to hide the recipient’s address.
Such way guarantees the privacy of the sender and the recipient. Monero can be bought on Poloniex, Bitfinex, Livecoin, and Kraken crypto exchanges. It is possible to store Monero via an online wallet. More secure is its computer wallet. Due to its privacy, the popularity of the coin is expected to grow, so it makes sense to add a coin to an investment portfolio.
Advantages
• Increased privacy. Cryptocurrency is suitable for those who are afraid of deanonymizing network transactions. • Unlimited and difficult mining. • It takes less time to find blocks. • Resistance to the centralization of mining capacities.
Disadvantages
• Resources. All currency protection technologies require impressive machine performance for normal operation. The Monero block size is constantly growing, and this requires additional resources of network participants. • The popularity in the dark web leads to problems in working with regulatory authorities, exchanges often delist it. Speaking of reputation, Monero’s reputation is far from the best. The coin is often used on the dark web as payment for various illegal services. It happens to almost all crypto coins that provide privacy. • Large transaction sizes. Since Monero Blockchain is five times larger than the Bitcoin Blockchain in terms of one transaction. • Problems with scalability.

Dash

The Dash platform is a classic decentralized Blockchain-based payment system and the most technologically advanced cryptocurrency. It implements multi-off-chain money transfers without loss of reliability and overall security of the Blockchain. Its confidentiality is rather an additional option that can be used optionally. In the case of anonymity, it is possible to send a hidden transaction, but at a more expensive cost, which also requires additional time. Dash developed a hashing algorithm with eleven cryptographic functions-X 11 for the first time. The coin developers have released apps for other platforms. Today it is possible to use Dash for IOS, Zeal for Linux, LovelyDocs for Android and Velocity for Windows.
As well known, the CoinJoin is an anonymization method for crypto transactions, which is used by Dash as an improved version called the PrivateSend. Its mixing sessions are limited to 1,000 DASH for each session and will require multiple mixing sessions to anonymize a large amount of money.
Advantages
• High transaction speed. It is achieved via InstantX technology, which enables the confirmation of operations in less than 4 seconds. • Law transaction fees. • Energy consumption. Unlike Monero, it does not require a lot of power or high commission costs.
Disadvantages
• “Transparency” of the network. Without triggering the “mixing” mechanism, the directions of transactions and their balances are publicly visible to everyone. • Lack of proper cryptographic technologies that provide privacy, but can provide a sufficiently high level of protection. • Transaction visibility to the founders and the team.

Zcash

An open-source decentralized cryptocurrency that provides users with maximum privacy. Zcash is the first private cryptocurrency, using cryptographic protocol zk-SNARKS, a zero-knowledge security layer. It allows users to make hidden and open transactions.
Mathematically guaranteed privacy is something cryptocurrency can not be proud of. This fact makes the currency specific. All Zcash coins are identical, it means that interchangeable coins do not contain information about past use created. In this regard, the connection of coins with their history on the Blockchain is broken, which makes them universal and identical to each other. Zcash blocks are generated 4 times faster than Bitcoin. The currency trades on Huobi, Bitfinex and Binance exchanges, and after purchase, it can be stored on the exchange’s internal wallet, as well as transferred to Jaxx, Cryptonator and Coinomi multi-currency wallets. Coins can also be stored on hardware wallets like Ledger and Trezor.
Advantages
• Privacy. Since no information except the time stamp, is recorded in the Blockchain, transactions cannot be tracked, and the identity of the sender and recipient is almost impossible to establish. • Interchangeability. Due to interchangeability, all coins have a “clean” history. This means that it is practically impossible to determine which transactions coin was used. • Security. Lack of information about user keys, which protects user wallets and the network.Mining energy efficiency. Zcash mining hardware consumes less electricity than Bitcoin mining ASICs. • The difficulty of mining. Zcash is beneficial for those who want to get coins for block creation. Bitcoin mining becomes more and more complicated, so miners cannot earn enough money via their computers with high capacity.
Disadvantages
• 6 users can decide to leave the transferred data completely open. • It takes a lot of calculations to complete a transaction. • Insecurity. There are fears that the system could be hacked, or users may accidentally open the data. • Legally ZCash is supported only by Linux, however, it provides users with wallets for other platforms: Jaxx, Ledger, Trezor, Trust, Zecwallet, Ibitcome, Exodus, Guarda, Coinomi, Cobowallet, and Bitgo.
Private cryptocurrencies are necessary for anyone who values the privacy and confidentiality of financial transactions. Privacy can generate more value, than danger, as Eric Hughes says: “Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world”.

What are your censorship stories that bitcoin would fix

I saw another post that I thought was asking for censorship stories, but it was just a different type of complaint, so I thought to make this post.
So... What are some stories you'd be willing to share that woke you up to how much centralized censorship there is today, and why bitcoin might help.
I'll start:
2015, I wanted to check out bitcoin so I got some from a faucet and downloaded bitcoin-core and the blockchain. Few days later I got a letter from Comcast (my ISP) saying that they recognized suspicious traffic on my MAC and suggested I call support to have a tech come out and run a virus scan. I ignored it, but it prompted me to log into my ISP account, which I never do. Sure enough I had a stack of emails from Comcast to my ISP email address saying the same thing. Turns out they were routinely doing port scans on my network looking for open ports. When I opened my NAT firewall for bitcoin-qt they saw this as "suspicious traffic".
Not really "censorship" but definitely creepy.
2016, getting kinda freaked out by the previous, I decide to run my client over TOR. This was on a linux box so I no longer had the blockchain. So I set it up and start pulling down blocks and I'm now satisfied that my node is reachable without having to punch a hole through my NAT or get nasty letters from Comcast. Then all of the sudden my connection drops. Assuming it's just crappy internet I don't think about it for the rest of the week. Weekend comes and I have some free time so I fire up my linux box and my tor node then boom.... my connection drops. Turns out every time I fired up my tor node they would "re-provision" my cable modem. Filed a shit-ton of issues, letters and social media posts.
End result was that the directed me to their terms-of-service which explicitly prohibit the use of "peer-to-peer" software or running any internet "servers" on their service.
2018, My previous encounters got me interested in Tor, I2P, and other types of networks. I wrote a series of posts about it. Since all my spare money goes into DCA I decided to go with a free dynamic-dns service for a static hostname. Eventually, since tons of scammers use the same free dynamic-dns service, both reddit and facebook have a site-ban on any URL linking to it. Luckily my gh-pages link does a 301 redirect so I can link to it indirectly here: https://brianddk.github.io/darkweb . For fun try pasting the URL it redirects to in a reply post and you will find the site automod kick in and remove it. Won't affect your user account though.

Bitcoin Verde: A New Consensus Full-Node Implementation for BCH

For the past year I have been working on a full-node in Java, completely from scratch. Today, after so much research, work, communication and testing, I am very happy to release the first beta version of Bitcoin Verde--on the genesis block's 10th birthday, no less!
Bitcoin Verde is a ground-up implementation of the Bitcoin (Cash) (BCH) protocol. This project is a full node, blockchain explorer, and library.
In the past, lack of a diversified development team and node implementation have caused bugs to become a part of the protocol. BCH currently has roughly three common full-node implementations (Bitcoin ABC, Bitcoin XT, Bitcoin Unlimited). However, these implementations are forked versions of Bitcoin Core, which means they may share the same (undiscovered) bugs. With a diverse network of nodes, bugs in the implementation of the protocol will result in incompatible blocks between the nodes, causing a temporary fork. This situation is healthy for the network in the long term, as the temporary forks will resolve over time and the intended ruleset becoming the consensus.
Bitcoin Verde approaches many of the design decisions made by the reference client very differently--most prominently, Bitcoin Verde stores the entire blockchain in its database, not just the UTXOs. Because of this, reorgs are handled very differently and it's even possible to validate multiple forks at the same time. In fact, you can view http://bitcoinverde.org/blockchain/ to view some of the forks our instance has encountered. The node considers the chain matching its consensus rules and having the most PoW to be its "head" chain.
I've spent a lot of time talking with the Bitcoin XT group to attempt to stay in-step with their consensus rules as much as possible, and it my goal to ensure we are diversifying the implementation of the network, NOT separating it. Because of that, please be sure to treat this release as a beta. Currently Bitcoin Verde does not have a mining-pool module finished, but once confidence has been raised about the consistency of the rulesets, this is a feature we intend on implementing and Bitcoin Verde will become a mining full node.
Every component is multithreaded, including networking, validating, mempool acceptance, etc. It is my hope that during the next network stress-test, Bitcoin Verde can help to gather statistics on forks, transactions per second, and block/tx propagation time.
Bitcoin Verde has its drawbacks: it's a resource-hog. Since the whole blockchain is indexed, the disk footprint is about 600GB. Initial-block-download memory usage is configurable, but is about 4 GB, (1.5 GB for the database + 1/2 GB for the node + 1 GB for the tx-bloom filter + 1 GB for the UTXO cache). Another drawback is that Bitcoin Verde "does more stuff"--it is essentially a block explorer, and because of that, the initial block download takes about 2-4 days to index all of chain and its addresses.
Bitcoin Verde has been tested for weeks on Linux (Debian) and OS X. The node has not been tested well on Windows and it may in fact not even sync fully (only a Windows issue, currently). If you're a Windows user and are tech-savvy, feel free to give it a go and report any issues.
I wanted to give my thanks to the Bitcoin XT team for being so welcoming of me. You're a great group of guys, and thanks for the conversations.

⚡ Lightning FAQs ⚡

If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily,
Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Lightning is already being tested on the Mainnet Twitter Link but as for a specific date, Jameson Lopp says it best
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source

Bitcoin Stack Exchange Answer
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges
Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Stack Exchange Answer
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above.
All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
No -- Source
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source
LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-)
For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user.
Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
Stack Exchange Answer
Can the Lightning Network work on any other cryptocurrency? How?
Stack Exchange Answer
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?

Bisq not connecting to local bitcoind

Hi, I run Bisq 1.1.7 (and before it's predecessor with the same problem) on my linux box, and I have problems connecting to my local bitcoind. The log says:

I tried the --rpcXXXX commandline options with no change. My node is fully synced and not pruned.
netstat shows:

tcp 0 0 0.0.0.0:83330.0.0.0:* LISTEN 8542/bitcoin-qt
with 8332 being the rpc port.
