L2chain: Towards High-performance, Confidential and Secure Layer-2 Blockchain Solution for Decentralized Applications
Summary: L2chain: layer-2 that stores only state digests on-chain, using split-execute-merge with RSA accumulators to lock/update partial state in parallel and a witness cache to cut latency. Confidential TEE off-chain execution plus a two-step anti-rollback ordering protocol; demonstrates substantial throughput gains in both permissioned and permissionless settings.
