Syscoin is a decentralized, modular blockchain platform designed to scale Bitcoin for a new generation of Web3 applications. It operates as a Bitcoin Layer 2, uniquely combining Bitcoin's robust Proof-of-Work security—via merged mining—with a highly scalable, EVM-compatible execution environment. Its dual-chain architecture consists of a native UTXO chain and the Network-Enhanced Virtual Machine (NEVM), enabling the deployment of smart contracts and dApps. Key innovations include Rollux, an optimistic rollup suite for high throughput and low fees; BitcoinDA, a Layer 1 data availability solution; and a network of approximately 2,700 Sentry Nodes that provide a finality layer through multi-quorum chainlocks, protecting against re-orgs and 51% attacks. The ecosystem is powered by its native utility coin, $SYS, and is focused on providing a secure, low-cost, and decentralized foundation for financial applications, smart cities, and more, positioning itself as a comprehensive execution layer for the Bitcoin network.
