Well ... Without withdraw nostr merit (it is far different than bitcoin) ... It would be a mess ..

Bitcoin it is mostly a p2p client 2 client protocol. It is very Important that each node will behave at the same to keep transactions and mining block verifications. Different on this will behave as a high number of block chain forks with a completely splited ones .. The great of bitcoin nodes it is being the same coding and behave the same, to have a single block chain banning out nodes that behave differently .. Nodes are greatly decentralized because they are able to run on small hardware that it is affordable by everybody. Only mining it is more centralized because hardware and electricity expenses are very high .. But the mining work it is anyway checked by the nodes that are the folks ... The bitcoin consensus it is apon choosing code features to apply on block chain handling at first. If a fork will be done, the freedom of choosing to apply it will decide the future of bitcoin and the block chain .. This already happened in the past and the result it is what it is today bitcoin and how the its software forks ended out ...

Thanks for your work on nostr!
