Description
Technical Field
The invention relates to the technical field of computers, in particular to a verification method and a verification device applied to a block chain node.
Background
Each node in the blockchain network is equivalent to each computer or server terminal storing all the block data. The production of all new blocks, as well as the verification and accounting of transactions and broadcasting them to the network-wide sync, is done by the nodes.
The node is the miner which we commonly call. The different power of each miner determines how much billing rights it can allocate and how much rewards it can earn.
The first generation of consensus mechanism for block chains is called POW, which is a workload proving consensus mechanism and is commonly called mining. Thousands of hash hits must be performed to create a new block. These operations consume much power and cause energy waste, so they are also affected by the scale. Even more feared is that once most of the computing power is monopolized, decentralization is threatened.
The second generation of consensus mechanism called POS is the rights and interests identification mechanism, which decides who has more accounting rights according to the amount of money held and the time. The recognition mechanism has the advantages of avoiding energy consumption, but has the disadvantages that the speaking right is controlled by the large user holding the money, the characteristic of central collection right is formed, and the characteristic runs counter to the original intention of decentralization of the block chain.
The third generation consensus mechanism is DPOS, and the biggest characteristic of the mechanism is that an election system is added on the basis of POS right certificate. The super nodes which finally obtain the billing right and are produced by voting of all the money-holding users can perform billing, so that the energy waste can be greatly reduced, but the calculation requirements on the super nodes are high due to the centralized calculation on the super nodes, and the efficiency of the super nodes directly influences the billing efficiency, so that the mode has weak capacity of dealing with large-scale data, and the development is restricted.
