Stateless Verification and Efficient Data Retrieval

Overview of the Architecture

The Corpus Core Colibri Client (C4) is a trustless, stateless, ultra-light client designed for secure and efficient blockchain verification. It operates without maintaining a blockchain state or participating in the peer-to-peer network, instead relying on cryptographic proofs for verification.

  • Stateless Design—This design does not store blockchain history but verifies state transitions, account information, and transaction information using cryptographic proofs.

  • Proof-Based Verification—This method authenticates blockchain data using sync committee signatures, Merkle proofs, and zk proofs. Additionally, in Layer-2 usage, it verifies rollup proofs, including zero-knowledge and fraud proofs, ensuring the correctness of Layer-2 state transitions.

  • Multi-Chain Compatibility—Supports multiple Layer-1 and Layer-2 networks for interoperability.
