The Bitcoin White Paper is a seminal document written by Satoshi Nakamoto, the creator of Bitcoin, that describes a proposal for a peer-to-peer electronic cash system ¹. Originally published in English, the document has been translated into several languages, including Portuguese ².
The document addresses the solution to the double-spending problem using a decentralized network, where nodes express acceptance of a block by creating the next block in the chain, using the hash of the accepted block as the previous hash ³.
