Embodiment Construction

[0019] This paper describes techniques for managing a blockchain-based centralized ledger system. These technologies typically involve a blockchain-based centralized ledger system (e.g., a general-purpose auditable ledger service system), which uses the data structure of the blockchain to take advantage of the immutability, reliability, and reliability of data stored on the blockchain. and trustworthiness. The centralized ledger system can obtain trusted time stamp information from a trusted time server (for example, a third-party globally recognized time authority) independent of the centralized ledger system. The centralized ledger system can take advantage of the trust established on the timestamp information provided by the trusted timing server, and integrate the trusted timestamp information into the centralized ledger system for data stored on the blockchain, which can further Enhance the trustworthiness, auditability and legality of stored data.

Abstract

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for managing blockchain-based centralized ledger systems. One of the methods includes: transmitting a timestamp request for a to-be-timestamped block in a blockchain to a trust time server by a ledger server in a centralized ledger system that stores data in the blockchain, the trust time server being associated with a trust time authority and independent from the centralized ledger system, the blockchain including a plurality of blocks storing transaction data, receiving a timestamp and associated signature for the to-be-timestamped block from the trust time server by the ledger server, and storing information of the timestamp and the associated signature for the to-be-timestamped block in the blockchain by the ledger server.

Description

technical field [0001] This article deals with managing a blockchain-based centralized ledger system. Background technique [0002] Ledgers are often used to record the history of transactions, such as economic and financial activities in an organization. Ledger-like applications such as custom audit tables or audit trails created in a relational database have been built to maintain an accurate history of the application's data. However, building such applications is time-consuming and prone to human error. And, since relational databases are not inherently tamper-proof, any changes to the data are difficult to track and verify. [0003] A distributed ledger (DLS), which may also be referred to as a consensus network and / or a blockchain network, enables participating entities to store data securely and immutably. Without referencing any specific use case, DLS is often referred to as a blockchain network. Examples of types of blockchain networks may include public blockch...
