B² Network is a Bitcoin Layer2 network that is over 50x cheaper and 300x faster than the Bitcoin network. It employs Bitcoin-level security with Bitcoin POW (L1) & Zero-Knowledge Proof (L2). Users can interact with B² using various wallets and enjoy easy access with BTC or ETH addresses via account abstraction. The network also allows for easy construction and migration of dapps from EVM-compatible chains and supports ZK-Rollup solutions using Bitcoin as a settlement layer.
