Problems solved by technology

At the same time, each transaction to be recorded in the blockchain needs to consume a lot of handling fees. If the transaction process is too complicated, the corresponding transaction handling fee will also increase, and the transaction cost will increase accordingly.
In addition, the blockchain will disclose the detailed process of the transaction to the public, so it cannot satisfy the confidentiality of the transaction, which is something that many parties involved in the transaction do not want to see

Embodiment Construction

[0040] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0041] Such as figure 1 As shown, an off-chain execution transaction system based on the blockchain contract layer includes participants and a state channel established between the participants. There are at least two participants. Participants can authorize agents through signatures. The state The channel includes two parts, on-chain and off-chain. There are smart contracts deployed on the chain and off-chain. The smart contracts include the root contract deployed on the chain and the off-chain contract deployed on the chain. Arbitration contracts and prophecies are also deployed on the chain. machine contract.

[0042] Such as figure 2 As shown, the root contract is used for final settlement, which includes the hash value of the off-chain contract, the public key address of the participant, the...

Abstract

The invention discloses a block chain contract layer-based method and system for executing a transaction under a chain. The system comprises participants and a state channel established between the participants, the state channel comprises an upper chain part and a lower chain part; intelligent contracts are deployed on and under the chain; wherein the intelligent contract comprises a root contract deployed on a chain and an offline contract deployed under the chain; wherein an arbitration contract and a predictor contract are further deployed on the chain, the root contract is used for finalsettlement, the offline contract is used for executing the transaction process, the arbitration contract is used for checking operation when the participant has an opinion to the offline transaction,and the predictor contract is used for providing necessary external data. According to the method and the system for executing the transaction under the chain based on the block chain contract layer,the influence of the delay of the block chain network on the complicated transaction process can be reduced, the commission fee generated in the transaction process can be reduced, and specific transaction details can be kept secret.

Description

technical field [0001] The present invention relates to the field of block chain transactions, in particular to a method and system for executing transactions under the block chain based on the block chain contract layer. Background technique [0002] In today's information society, data plays an increasingly important role. Data sharing and trading has become a hotspot in current technology and business. Moreover, due to the big difference between data and traditional commodities, such as easy to lose, easy to copy, and need to be kept secret. Therefore, there are higher requirements for transaction processing capability, traceability of transaction process, integrity and reliability of transaction data. [0003] However, in traditional trading methods, the conclusion of a transaction generally needs to rely on a third-party transaction center. The processing capacity of the transaction center will affect the efficiency of the transaction, and the failure of the transacti...
