Hash – Bitcoin Wiki

Mining Bitcoin

Bitcoin mining is analogous to the mining of gold, but its digital form. The process involves specialized computers solving algorithmic equations or hash functions. These problems help miners to confirm blocks of transactions held within the network. Bitcoin mining provides a reward for miners by paying out in Bitcoin in turn the miners confirm transactions on the blockchain. Miners introduce new Bitcoin into the network and also secure the system with transaction confirmation.

What is the counter argument to the argument that bitcoin isn't decentralized? Because a lot of it's hashing power is in China and their government could possibly attack bitcoin.

ELI5: What is a hash rate and how does it affect the price of bitcoin?

submitted by ZenNate to BitcoinBeginners [link] [comments]

People say bitcoin's security is backed by the hashing power of the miners, and if the miners are not incentivized then they will not mine to secure the chain. What if everyone has a miner that gives a little mining power to this chain in all of their appliances?

Bcash originally was on the path that s2x is on but responded to outrage by users and adopted a prudent approach and deployed actual replay protection.
Bitcoin Cash was a minority fork and thus felt responsible to implement the replay protection on its side.
From what it looks like SegWit2x is the majority chain (based on hashing power) and thus does not feel obligated.
Their 'opt-in' doesn't work because to make use of it requires replacing all existing software-- including signing code baked into hardware security modules
Would SegWit2x implement a strong replay protection they would have the same problem. (many wallets are still not working with Bitcoin Cash).
For a majority fork that would be like shooting in your own foot. Why would they want to do that?

How do miners steal coins without the private key?
a simple majority of hashpower opens up the time window via timewarp

Assumed valid is not at all the same thing.
Fair enough. That makes sense - using a hash is a known entity.

There is no need to "attack" a minority chain. No one will care about it. It will have almost zero hash power, will take months to propagate a single block and will die out when no one supports it.
You do realize what happens when you fork a chain and dump it at current diff onto 5% or so of the hash power, right?
How about them 5 hour blocks with max diff drop at current? Yeah. That chain won't recover. Ever. This isn't Ethereum classic, where a few GPU miners can keep pushing the chain.
This is Bitcoin. When 90% of hash power fork it, the minority chain is irreparably screwed. Unless you plan on investing $200 million in ASIC over the weekend.

Centralization in crypto refers to what degree hash power is owned by a single entity, or even how centralized it is geographically.
Authority is the issue of a group or person exerting influence on the network.
Before Ethereum moves to POS, in which case a highly centralized ownership of tokens could become an actual issue, Ethereum is less centralized than Bitcoin THOUGH more Authoritarian I would agree.
Bitcoin is by far the most centralized crypto of all already, so if that scares you it's a bad choice.
