O documento descreveu um método peer-to-peer de transferência de dinheiro sem o uso de instituições financeiras. A Criptomoeda conhecida como Bitcoin ou BTCestreou em 2009. As transações são registradas em um livro-razão público (umcadeia de blocos) por entidades conhecidas comomineirosque se envolvem em um processo chamadoprova de trabalho. Os mineradores são recompensados por fazer isso obtendo Bitcoin recém-cunhados. Alguns proponentes veem o BTC como uma alternativa às moedas fiduciárias e uma proteção contra a inflação.
