Intelligent contract processing method and apparatus

Abstract

The embodiment of the invention provides an intelligent contract processing method and apparatus. The method comprises the following steps: a first transaction node obtains the contract signed by a second transaction node from a storage node according to the address information of the storage node; the first transaction node re-signs the contract signed by the second transaction node to get the contract after the secondary signature; and the contract after the secondary signature is stored in the storage node. According to the intelligent contract processing method and apparatus provided by the embodiment of the invention, the identity information of both transaction parties is broadcasted in a block chain network and store the address information of the storage node with the contract viathe transaction nodes instead of broadcasting the contents of the contract into the block chain network, as the size of the address information is less than the size of the contents of the contract, the transmission pressure of the block chain network is reduced, and for a single node in the block chain network, the storage space of the single node is saved, meanwhile, the contents of the contractare stored on the storage node instead of broadcasting to the block chain network, thereby improving the security of the transaction.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for processing smart contracts. Background technique [0002] Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm for programming and manipulating data through smart contracts composed of code. [0003] Smart contracts are considered network servers, but these servers are not set up on the Internet using IP addresses, but on the blockchain. The cod...

Problems solved by technology

[0004] In the existing technology, the content of the smart contract itself needs to be broadcast to the blockchain network, and all nodes in the blockchain network need to store the smart contract. If the storage space required by the smart contract is large, it will not only lead to The transmission pressure of the network is relatively high. For a single node in the blockchain network, a single node needs to have a large storage space. In addition, broadcasting the content of the smart contract itself to the blockchain network will lead to transaction security. decreased sex
