Method and system for allocating and storing block data

Abstract

The invention discloses a method and system for allocating and storing block data, wherein the method includes the following steps: a transaction receiving node receives the transaction and judges whether the transaction is a key transaction; In the key transaction tree; if not, the transaction receiving node determines the target node according to the transaction and the public key of the transaction sending node, and the encapsulation node obtains the transaction and encapsulates it into the general transaction tree corresponding to the target node; among them, the key transaction is the whole network For transactions that all nodes care about, the encapsulation node is selected by the nodes of the whole network through the consensus algorithm; the encapsulation node calculates the hash value of the root of the key transaction tree and all general transaction trees and saves it in the new block, and the new block and the newly added transaction Carry out network-wide broadcast; each node in the entire network updates the key transaction tree and the general transaction tree corresponding to its own node to the local. The invention can effectively reduce the storage space, ensure the prevention of double-spending attacks, and facilitate the quick search of transaction data.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for allocating and storing block data. Background technique [0002] Blockchain technology is expected to provide core technical support for the next generation of trusted Internet technology. At present, its main bottleneck is not only the low consensus efficiency resulting in low system throughput, but also the chain data structure that only increases and does not decrease. The high demand is also one of its key problems. [0003] One of the more common ideas is to divide the blockchain data into different nodes for storage according to certain rules, so as to reduce the storage pressure of a single node. At present, the side chain technology widely used in the industry can reduce the overall storage pressure of the system to a certain extent. However, since the same node can join different side chains at the same time, and different side chains are g...
