Block chain storing transaction information and account information separately

Abstract

The invention discloses a block chain storing transaction information and account information separately. Each node is composed of two block chains, wherein one block chain TBC is used for processing transaction information, and the other block chain ABC is used for maintaining account information. The block chain TBC for storing transactions reads account information from the block chain ABC for maintaining accounts or writes account information into the block chain ABC for maintaining accounts. A scalable block chain system is realized. Under the condition that account information increases sharply, the ABC can maintain accounts on another physical machine, and the pressure of the transaction processing TBC node can be reduced significantly. Each TBC node and a corresponding ABC node are matched in use to constitute a complete block chain node. Meanwhile, the block building processes of TBC and ABC are the same, and the underlying block chain maintenance and the original block chain maintenance are the same. There is no need to update the original block building algorithm.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain for separately storing transaction information and account information. Background technique [0002] In current blockchain systems, including Bitcoin and Ethereum, transaction information and user account information will be stored in the same blockchain. For Bitcoin, UTXO is used to store unused transactions of each account. The amount of information of each account is very small, and the public key of the account is directly used as the account address. To query the information of each account, it is necessary to traverse all transactions involving the account in the query block. Ethereum uses the Merkle Patricia tree for indexing to speed up the search for information. None of the above-mentioned blockchains can easily expand in the case of a large increase in the number of accounts and account information. The present invention combines some cur...

If the account information is still stored in the blockchain, when the number of accounts increases greatly, a single node must not only store and maintain a large amount of personal information, but also process transactions between accounts and build blocks.
