Abstract

The invention discloses a block data distribution and storage method and system, and the method comprises the following steps: a transaction receiving node receives a transaction and determines whether the transaction is a key transaction, if so, the transaction receiving node broadcasts the transaction in the whole network, and a packaging node packages the transaction into a key transaction tree; if not, the transaction receiving node determines a target node according to the transaction and the public key of a transaction sending node, and the packaging node obtains the transaction and packages the transaction into a general transaction tree corresponding to the target node, wherein the key transaction is a transaction concerned by the nodes of the whole network, and the packaging node is selected by the nodes of the whole network through a consensus algorithm; the packaging node calculates hash values of roots of the key transaction tree and all the general transaction trees, stores the hash values in a new block, and broadcasts the new block and the newly added transaction in the whole network; and each node of the whole network updates the key transaction tree and the general transaction tree corresponding to the node to the local. According to the invention, the storage space can be effectively reduced, the double spend attack is prevented, and the transaction data can be quickly searched.

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...
