The trusted ledger database (LedgerDB) provides blockchain database services. The service combines the high performance and low latency of a centralized system with the non-tampering and non-repudiation of data in the blockchain. It avoids the high cost and threshold of access to the blockchain and is suitable for various data recordation and data tracing scenarios.
LedgerDB ensures that all data written into LedgerDB is highly reliable (tamper-resistant and non-repudiation). At the same time, any non-read operation of the ledger is recorded, thus realizing the high reliability of the data throughout the life cycle of the entire Ledger data. As the service provider of LedgerDB, LedgerDB did not have the ability and willingness to modify the data, thus achieving the "self-certification" of the service provider.
- The storage layer uses the block-chain storage structure ensured by digital cryptography and the improved data structure of the Merkel transaction accumulator to ensure the tamper resistance of all data stored in the ledger.
- Application layer: adopts the multi-party signature mechanism, which ensures that once data is stored, it cannot be tampered with or verified by any participant.
- Public network layer: introduces a trusted third-party Time Service Center to stamp data with a trusted timestamp, ensuring data credibility in the time dimension.
System High Performance
Based on the core technology independently developed by the universal audited ledger team, data operations on a single ledger and single client can reach 300,000 TPS, with a response delay of milliseconds.
Reduced Storage Costs
In data storage or data tracking scenarios, LedgerDB has lower storage costs than the consortium blockchain solution in scenarios. In the consortium chain, a minimum of four nodes are required. The nodes are stored on cloud disks, and each node stores three copies of data. However, LedgerDB is a centralized service and only needs one node to store three data copies.
Low access cost
LedgerDB provides common database interfaces to allow technical engineers to access it without learning a new contract development language.
Under the premise of ensuring the characteristics of other products, LedgerDB supports the simultaneous use of the same ledger database by multiple participants, better to meet the business scenarios requiring multi-party collaboration.
Quick data verification
A new chain-like block storage architecture is used to verify the credibility of Ledger data in milliseconds.
Natively traceable data
It provides users with a customizable "data clue" function, which can be used to associate data. Combined with the "high reliability of data" feature of LedgerDB, the data associated with the data clue directly has tamper-resistant data traceability and traceability capabilities.
Working with member permission management, the regulatory authority and the regulated authority can use the same LedgerDB to meet the requirements of multiple parties.
