Problems solved by technology
However, in Ethereum transactions, smart contract transactions consume more computing resources than ordinary transactions, and the read and write operations on the database are more complicated, so the execution speed is slow
At the same time, every smart contract transaction needs to be executed once by all full nodes, and every transaction sent to the smart contract requires all full nodes to consume computing resources to verify, which seriously affects the transaction execution efficiency of the entire system

The invention discloses a transaction processing method of a block chain system. The transaction processing method of the blockchain system comprises a bottom layer chain and a plurality of upper layer contract chains, each upper layer contract chain corresponds to an intelligent contract, and each node device in each upper layer contract chain belongs to the bottom layer chain and subscribes to the intelligent contract corresponding to the upper layer contract chain to execute a transaction corresponding to the intelligent contract. According to the invention, the intelligent contract is separated from the underlying transfer transaction, and the node equipment participating in the intelligent contract collectively maintains the transaction data and the contract state data related to thecontract, so that the execution performance of the intelligent contract can be suitable for a specific application scene. The underlying chain does not need to execute the intelligent contract transaction, so that more transfer transactions can be packaged in blocks with fixed sizes at the bottom layer, and the performance of the underlying transaction chain can be improved.
Description
technical field [0001] The invention relates to the technical field of block chains, in particular to a transaction processing method of the block chain system. Background technique [0002] The blockchain builds a distributed database, the authenticity of which is maintained by many nodes in the network, and each node has the right to decide on each record. This means that each node (full node) in the network must store a complete ledger data, and the ledger data is composed of transactions as the basic unit, which means that each node in the network must have a An execution has confirmed every transaction contained in the block. This serial execution method makes the performance of the current blockchain inefficient. Taking Bitcoin as an example, in terms of performance, it currently only supports a transaction throughput of 7 transactions per second, which makes it difficult for it to undertake timely confirmation of a large number of transactions. , obviously cannot me...
