A Complete Guide - Run Node Ink L2 Blockchain Built on OP Superchain by Kraken

A programmable account layer upon Nervos CKB.

A Hybrid ZK-Optimistic Network Extension with Flexible Verification for Solana

Blockchain kits and framework for building blockchain integrated infrastructure services (with EVM-compatible network), written in go.

Real-time cryptographic watchtower and reputation engine for Unichain. Validates Intel TDX attestations, detects sequencer equivocations, and provides a programmatic 'confidence score' API for 200ms Flashblocks.

An optimistic rollup with fraud proofs and a bisection dispute game — a sparse Merkle state, one shared state transition function, and an L1 that convicts a lying sequencer by re-running a single transaction. Includes an interactive dispute visualization.

A Clarity smart contract implementing a Bitcoin-anchored optimistic rollup system for enhanced transaction efficiency and scalability on the Stacks blockchain. It ensures secure off-chain transaction management while maintaining on-chain security.
