Smart Bitcoin Cash, often referred to as smartBCH, serves as a sidechain for Bitcoin Cash, designed to innovate and expand the potential of blockchain technology. It seamlessly integrates with Ethereum's EVM and Web3 API, delivering enhanced throughput for decentralized applications (DApps) in a manner that prioritizes speed, security, and decentralization. With its EVM and Web3 compatibility, smartBCH features a brief block interval tailored to facilitate DeFi applications effectively. The projected throughput can reach an impressive one billion gas every 15 seconds, making DeFi accessible to a broader audience at minimal costs. Developed entirely from the ground up, smartBCH utilizes multiple low-level libraries to harness the full capabilities of hardware, particularly its natural parallelism. Furthermore, it offers additional rewards to Bitcoin Cash miners and holders, allowing them to participate in electing Smart Bitcoin Cash validators using their hash power and locked coins. By creating trustless, non-custodial two-way pegged gateways, the platform enables secure bidirectional transfers of BCH and supports various sidechains associated with Bitcoin Cash. This innovative architecture not only enhances the ecosystem but also encourages community engagement and participation in the growth of decentralized finance.
