B² Network (B2) is a pioneering Bitcoin Layer 2 solution that uses zero-knowledge rollup technology to make Bitcoin transactions faster and cheaper while keeping its top-tier security. It features an EVM-compatible environment, allowing traders and developers to use Ethereum-style smart contracts and DeFi applications directly within the Bitcoin ecosystem.
For financial utility, the network supports staking and yield-generating products like MiningSquared, which lets users earn passive rewards on their BTC and B2 holdings. The trading experience is enhanced by the B² Hub, which provides ultra-fast "pre-confirmations" (as quick as 150ms) to ensure orders are executed at near-instant speeds.
Looking to the future, B2 is evolving into an AI-native economic layer, integrating autonomous AI agents and a native BTC-backed stablecoin (U2) for automated commerce. As we move through 2026, the project aims to bridge the gap between Bitcoin's massive liquidity and the growing demands of decentralized AI and advanced finance.
