The Architecture

OneLedger enables you to focus building your business application through OneLedger modularization tools, which will communicate with OneLedger protocol using its API gateway. This mechanism will make your business application interact with different public and private blockchains synchronously through corresponding side chains implemented in OneLedger platform.

The Consensus

OneLedger defines a three-layer consensus protocol to enable more effective integration of different blockchain applications. Business logic can be implemented by the first layer – a configurable role-based consensus protocol leveraging hierarchical grouping similar to the structure of Merkle Tree. The side chain consensus protocol can move consensus traffic from the main chain with public consensus to the side chain with high performance and efficiency. OneLedger block structure enables the synchronization and reference between the three-layer consensus.


  • Business Modularization
    • OneLedger forms a realizable and verifiable blockchain network which is modularized from real-world functionality, based on the sharing and immunity mechanisms provided by blockchain techniques.
  • Protocol-based Blockchain Communication
    • All transaction data and real source records are written into distributed nodes by validation mechanism of data sharing through OneLedger protocol. OneLedger protocol enables communication and access across the blockchain, and allows for deployment and extendability across various Blockchain networks.
  • High-performance Transaction
    • High-performance transactions enabled by a uniquely-engineered role and arbitration mechanism allowing for storage of data in a hierarchical structure.
  • Multi-chain Runtime Support
    • Focuses on providing a consistent runtime which is compatible with various blockchain protocols and application development stacks
