What is BSquared Network?
BSquared Network, also written B2, is a Bitcoin layer-2 network that aims to extend Bitcoin beyond a store of value by supporting smart contracts and DeFi. It uses a zero-knowledge rollup design with EVM compatibility, so Ethereum-style applications can run while settlement ties back to Bitcoin. The testnet appeared in late 2023 and the network built out its ecosystem through 2024. B2 is the network's native token, used for activity across the chain. It launched in early 2025 and began trading on exchanges in April 2025. This is a young, early-stage project in the fast-moving Bitcoin layer-2 sector, where designs are still maturing and adoption is unproven, so treat it as speculative and do your own research. You can follow the BSquared Network price and hold B2 in a self-custody wallet, with your keys staying in your hands.
