Abstract

The invention relates to a data archiving method and system on a blockchain. The method comprises the steps of dividing traditional full nodes in the blockchain into accounting nodes and historical archiving nodes according to function setting; when the blockchain is extended to a capacity limit value set by the system, triggering an archiving operation; and replacing an archived first blockchainsegment with an index block at a corresponding position of the accounting node blockchain, wherein the index block is used for pointing to archived historical data of the historical archiving node. According to the method, the capability that a common user can be used as a full node to participate in accounting can be ensured, and the safety of a blockchain system is maintained; an account book iscompletely recorded without loss, and the whole historical process is traceable; the working efficiency of the blockchain system is improved, and the data pressure caused by time increase is reduced.

Description

technical field

[0001] The invention belongs to the technical field of block chains, and in particular relates to a data archiving method and system on a block chain. Background technique

[0002] Blockchain technology started with Bitcoin in 2009. As the first generation of blockchain technology, it is characterized by creating a new era of permissionless distributed ledgers based on P2P networks. In 2014, Ethereum improved the virtual machine on the basis of Bitcoin, using the complete Turing machine working mechanism to complete its founder's goal of building a computer on a distributed accounting system, creating a precedent for the application of "world computer" and creating the The smart contract system has become the leader of the second generation blockchain technology.

[0003] With the development of blockchain technology, the application of blockchain systems in various fields is becoming more and more extensive. Under the current technology, since the full no...
