Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In the embodiment of the present invention, refer to figure 1 , a method for rapid synchronization and simplified data storage of a blockchain system, the steps of the method for synchronizing the next block of the blockchain data structure are as follows:

[0027] A1: Add a local ledger hash to the block header of the blockchain data structure, and the local ledger hash refers to all the data of a complete local ledger;

[0028] A2: When the local node generates new ...

Abstract

The invention provides a mode for fast synchronization and simple and precise data storage of a block chain system, wherein an account hash is added in a block header data structure of the block chainsystem, which represents a hash summary of a complete account. During the synchronization of block chain system, synchronizing all block headers first, get the ledger hash from the latest block header, then according to the book hash, synchronizing a full account from the network, to reduce the synchronization of block data, on the one hand, the synchronization time and the storage space requirement of the whole node in the block chain system are greatly reduced; on the other hand, the old block data can be deleted at any time during the operation of the node in the block chain system, so asto reduce the storage space requirement in the operation process.

Description

technical field [0001] The invention relates to the field of block chain technology and block chain storage technology, in particular to a method for fast synchronization and simplified data storage of a block chain system. Background technique [0002] Currently, for blockchain systems, full synchronization of block data is a slow, bandwidth- and storage-intensive process. For a complete node, it is necessary to synchronize all block header data and block data so far since the blockchain system went online. The longer the system runs, the greater the number of transactions, and the greater the amount of data that needs to be synchronized. [0003] Taking the Bitcoin system as an example, by September 2018, the data that needs to be synchronized by a full node has exceeded 200G bytes (200,000,000,000 bytes), which is equivalent to the file size of 200 1080P standard-definition movies. Under the current network speed, it usually takes hours or even days to download. And th...
