The two main characteristics of Bitcoin, decentralization and trustlessness, are related to one of its core technologies, the blockchain (Blockchain or Block chain), which was first proposed in Satoshi Nakamoto's Bitcoin white paper and has been validated through over seven years of practice with Bitcoin, sparking a global wave of technological research. The Bitcoin blockchain is a series of data blocks generated through cryptographic methods that are linked together, with each data block containing information about transactions on the global Bitcoin network within a 10-minute interval.
