Abstract
The invention discloses a method, equipment and a storage medium for horizontally expanding a blockchain executor, belonging to the technical field of information.
Description
Technical Field
The present invention relates to the field of information technologies, and in particular, to a method, an apparatus, and a storage medium for horizontal extension of a blockchain executor.
Background
The blockchain is essentially a decentralized database, which is a sequence of related blocks generated by cryptography, each block containing information about the transactions over the network over a period of time. A network constructed using the blockchain technique may be referred to as a blockchain network, where the blockchain network includes a plurality of blockchain nodes, and any blockchain node may correspond to at least one blockchain, and any blockchain may include at least one block. Blocks (blocks) of different heights are connected by chains (chain), and the most important operations in block chain transactions are transaction validity verification (Auth), Consensus verification (Consensus) and contract execution.
Smart contracts (smartcontacts) are a computer protocol intended to propagate, verify or execute contracts in an informative way, which allows trusted transactions without third parties. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts.
Chain33 is an open-source, intelligent contract-enabled, common blockchain platform in which various types of contract transactions can be performed, including evm, coins, token, trade, privacy, and so forth. Under normal conditions, if the transaction is not in the peak period, the blockchain system usually does not need to accelerate the transaction processing, so as to promote the TPS of the whole system, and during the peak period of the transaction, the transaction volume of one or more types of transactions is often extremely large, so that the processing capacity of the system is insufficient, at this time, if the related hardware is deployed according to the most heavy condition of the transaction pressure in the peak period, so as to promote the performance of the system, the system does not need to use such high performance most of the time, so as to cause serious resource waste.
Therefore, there is a need for a method for horizontally expanding a blockchain executor, which is suitable for horizontally expanding the transaction processing capacity of a blockchain system without occupying the original hardware resources of the blockchain during the peak transaction, so as to effectively cope with the temporary processing pressure of the peak transaction.
