The Preservation Chain is a publicly accessible consortium blockchain platform initiated by FairSigning, leveraging blockchain technology and independent invention patents, in collaboration with notary offices, arbitration commissions, internet courts, copyright protection centers, judicial authentication centers, and CA institutions (Certificate Authority Institutions). It provides stable blockchain infrastructure services, convenient intermediate tools, and reliable solutions for the Internet application layer of various industries requiring evidence preservation. It significantly lowers the threshold for enterprises to apply blockchain technology, addressing issues such as easy tampering of electronic data, weak legal validity, and difficulty in online evidence collection. It ensures that the generation, preservation, verification, and final use of electronic data are synchronously supervised and notarized by relevant judicial institutions, effectively guaranteeing judicial validity. It truly realizes One-Click Arbitration, One-Click Notarization, and One-Click Authentication, making electronic data reliable electronic evidence.

Real-Time Digest Description: Digest information is the result of solidifying user information, original documents, timestamps, and other data, and is a direct manifestation of evidence preservation. Through digest information, we can provide users with relevant legally valid certificates. Meanwhile, the immutability of the digest is guaranteed through a specific mechanism. This immutability is technical, and even the evidence preservation center cannot modify it manually.

• 

  Traceability

  By entering the organization's signature to prove the original source of data, the historical records of data in the chain can be traced and are tamper-proof.
• 

  Security and Consensus

  ECDSA (Elliptic Curve Digital Signature Algorithm) is used for information transmission. Compared with traditional certificate signatures, it offers faster verification speed, higher strength, and a higher security coefficient.
• 

  Decentralization

  It adopts distributed accounting and storage, with no centralized hardware or management institution. Data blocks in the system are jointly maintained by nodes with maintenance functions throughout the system.
• 

  Tamper-Proof

  Once information is verified and added to the blockchain, it is permanently stored. The data in the blocks is irreversible, ensuring extremely high stability and reliability of the data.
