...individual or group using the name Satoshi Nakamoto. In January 2009, the Bitcoin network officially launched with the mining of the first block, known as the “genesis block.” The whitepaper proposed a radical idea: a decentralized digital currency that would operate without a central authority such as a government or bank. Instead of relying on trust in institutions, Bitcoin would rely on cryptography and a distributed network of computers to verify and record transactions. This innovation came in the wake of the 2008 global financial crisis, a period when public trust in traditional banking systems was severely shaken. Embedded in Bitcoin’s genesis block was a newspaper headline referencing bank bailouts—widely interpreted as a subtle commentary on the...
