Smart Bitcoin Cash (SBCH) is a sidechain of Bitcoin Cash designed to explore new ideas and unlock possibilities within the Bitcoin Cash ecosystem. It aims to provide a decentralised, high-throughput, low-cost, and easy-to-use infrastructure for cryptocurrency applications. SBCH is compatible with Ethereum's EVM (Ethereum Virtual Machine) and Web3 API, which are the de facto standards for blockchain decentralized applications (DApps). This compatibility allows SBCH to leverage the extensive ecosystem of Ethereum, enabling developers to deploy Ethereum-based smart contracts and DApps on the SBCH sidechain.

Smart Bitcoin Cash (SBCH) is used for several purposes, including shorter confirmation times, as SBCH has a shorter confirmation time compared to Bitcoin Cash, which enhances user experience for various applications, including decentralized finance (DeFi). It supports smart contracts and DApps by enabling the deployment and execution of smart contracts and DApps through compatibility with Ethereum’s EVM and Web3 API. This expands the functionality beyond simple transactions to more complex scenarios such as DeFi, gaming, and supply chain management. The SBCH infrastructure is optimized to handle higher throughput, making it suitable for applications requiring fast and numerous transactions. Additionally, SBCH serves as a testing ground for new features and optimizations that can later be implemented in the Bitcoin Cash mainnet. This includes innovations in parallel transaction execution and storage optimizations.
