A new distributed infrastructure and computing paradigm for contracts to program and manipulate data. Blockchain technology itself has many advantages: On the one hand, because the blockchain network can implement self-restraint through algorithms, any malicious deception of the system will be rejected and suppressed by other nodes in the network, so the blockchain system does not need to rely on The support and credit endorsement of the central authority can realize secure network transactions. On the other hand, because the blockchain adopts a one-way hash algorithm, and each newly generated block advances in strict linear order of time, the irreversibility of time causes any attempt to invade and tamper with the data information in the blockchain.
