Stumbled upon this White Paper by the evangelist´s super hero "Satoshi Nakamoto": https://bitcoin.org/bitcoin.pdf Abstract. A purely peer-to-peer version of electronic cash would allow onlinepayments to be sent directly from one party to another without going through afinancial institution. Digital signatures provide part of the solution, but the mainbenefits are lost if a trusted third party is still required to prevent double-spending.We propose a solution to the double-spending problem using a peer-to-peer network.The network timestamps transactions by hashing them into an ongoing chain ofhash-based proof-of-work, forming a record that cannot be changed without redoingthe proof-of-work. The longest chain not only serves as proof of the sequence ofevents witnessed, but proof that it came from the largest pool of CPU power. Aslong as a majority of CPU power is controlled by nodes that are not cooperating toattack the network, they'll generate the longest chain and outpace attackers. Thenetwork itself requires minimal structure. Messages are broadcast on a best effortbasis, and nodes can leave and rejoin the network at will, accepting the longestproof-of-work chain as proof of what happened while they were gone. So, what do we do if - God forbid - the internet network goes dark and we are all "lost in transaltion"? Yeah, I know - won´t happen, isn´t it evangelists?
