Multi-party competing digital asset transaction system and method based on smart contract

Abstract

The invention provides a multi-party competing digital asset transaction system and method based on an intelligent contract, and the system comprises at least four types of participating roles: a seller, a buyer, a transaction platform side, and a supervisor, the seller comprises a seller client interaction end, a seller transaction end, and a seller settlement end, and the buyer comprises a buyer client interaction end, a buyer transaction end, and a buyer settlement end. The transaction platform side comprises a transaction platform side client interaction end, a transaction platform side transaction end and a transaction platform side settlement end; the supervision side comprises a supervision side client interaction end, a supervision side transaction end and a supervision side settlement end; the system allows a plurality of exchange institutions, a plurality of financial institutions and a plurality of supervision units to complete transactions on a model, each transaction party firstly searches a required smart contract in a smart contract library of a platform through an interface provided by a transaction platform party, and if the required smart contract library cannot be queried, the transaction party needs to register and provide the smart contract by himself / herself; and the platform operates different smart contracts to realize transaction demands.

Description

technical field [0001] The invention belongs to the technical field of smart contracts, and in particular relates to a multi-party competing digital asset trading system and method based on smart contracts. Background technique [0002] The "smart contract" technology was proposed by Nick Szabo in 1994, which means that the terms of the contract can be actively enforced. After nearly 20 years of silence, Ethereum used this term around 2012, thinking that the code running on the blockchain system is a "smart contract", regardless of whether these codes are contract terms. However, after The Dao incident in 2016, people began to pay attention to smart contract technology and believed that it needs to be combined with the law. In 2018, Ethereum also admitted that it was inappropriate to use the term smart contract. [0003] In addition, in 2020, the Bank of England proposed that smart contracts or other software can be used for the following purposes: including checking the au...
