Description

Technical Field

[0001] The present invention relates to the technical field of contract management, and in particular to a blockchain technology contract management method and system. Background Art

[0002] A contract, also known as a covenant or agreement, is an agreement between equal parties to establish, change, or terminate civil rights and obligations. As a civil legal act, a contract is the product of consensus between the parties and is an agreement between two or more parties that agree on the intentions of the parties. Only when the intentions of the parties are legal can the contract be binding under national law.

[0003] The contract between human resources and enterprises for flexible employment is generally a paper contract. After both parties stamp and sign, there are special contract management personnel to store and archive it. The contract is very important from drafting to signing by both parties and then to safekeeping. However, if the paper contract is not kept properly, it is easy to be lost or damaged.

[0004] An electronic contract is an electronic agreement that clarifies the rights and obligations of both parties, mainly signed through data telegrams, e-mails, etc. However, electronic contracts, regardless of their format, are extremely easy to be tampered with and difficult to protect through legal means.
