Description
Technical Field
The invention relates to a contract confirmation method based on a block chain and a conference system based on the block chain.
Background
With the continued development of the economy, the number of contracts signed in commercial activities has increased dramatically. Traditional transaction activities typically involve the signing of paper contracts, but the signing of paper contracts presents a number of problems, such as distance problems. Because of distance or other reasons, if the parties signing the contract can not complete signing in the same place, one party generally needs to carry the contract to the other party after signing is completed, and if multi-party signing is involved, the efficiency is very low. In order to solve the above problems, the prior art generally adopts an electronic contract signing method. The existing electronic contract signing technology mainly has two modes of off-line signing and on-line signing. For off-line signing, each signing party needs to add an electronic signature of the own party and then sends the electronic signature to the next signing party, the process is complicated and difficult to control, and the electronic contract is easy to be tampered in the network transmission process. For the on-line signing mode, a signing platform generally adopts a data Certificate (CA) to verify signing parties of an electronic contract, and a trusted timestamp is added to a national time service center of a professional timestamp service institution after signing is finished to prove the legality, reliability and authenticity of the electronic contract. In the prior art, the electronic contract signing mode, whether off-line signing or on-line signing, has the problems of easy manual tampering and poor reliability and safety.

As shown in fig. 1, the conference system 500 includes a processor 300, a storage unit 100, and a blockchain-based distributed network 200.
The processor 300 is communicatively coupled to the storage unit 100 via the distributed network 200. The memory unit 100 stores a plurality of instructions adapted to be loaded and executed by the processor 300 to implement a blockchain based contract validation method.
In a specific implementation, the conference system 200 may further include hardware such as a display device, a camera device, a touch device, a speaker, a microphone, and the like, so as to facilitate interaction between parties participating in the conference.
Referring to fig. 2 to 3, the method for confirming a contract based on a blockchain may include the following steps.
And S101, generating a contract. The contract may be an electronic contract.
S102, broadcasting the contract to each participating node in the blockchain-based distributed network 200.
And S103, after confirming the contract and authenticating the contract, one node collects contract information to the generated new block and broadcasts the new block to each participating node.
And S104, verifying whether the new block is valid.
And S105, connecting the effective new block to the block chain.
And S106, the next node repeats the steps until all the nodes finish the authentication signing of the contract and connect the correspondingly generated new block to the block chain.
Wherein a node validates the contract and authenticates that the new block generated after signing may include multiple contracts.
In a preferred embodiment, the step S104 may specifically include the following steps.
S1041, each node calculates the workload certification.
And S1042, the node which calculates the result fastest obtains the authority of the verification contract.
