摘　　要：区块链技术通过哈希函数、默克尔(Merkle)树、非对称加密、对等网络、UTXO(未花费的交易输出)、工作量证明等,在对等网络构建了统一的分布式的数据库。分析了区块链技术是如何利用这些技术手段保证数据的去中心化、不可篡改和可溯源,并对区块链的应用场景进行了分析和展望。Blockchain technology use hash function,Merkle tree,asymmetric encryption,peer-to-peer network,UTXO(unspent transaction output),Proof-of-Work and other technical means to build a unified distributed database on the peer-to-peer network.It analyzes how the blockchain technology uses these technologies to ensure the decentralization,immutability and traceability of data.The application scenarios of blockchain are analyzed and prospected.
