What this skill does


# B² Network (BSquared)

Bitcoin L2 with EVM compatibility, ZK proof rollup combined with
optimistic challenge mechanism. Deployed 2024, growing 2025-2026.

## Architecture

- **EVM execution** (Solidity contracts).
- **ZK proofs** for state validity.
- **Optimistic challenges** as backup verification.
- **Bridge**: federation + planned BitVM upgrade.
- **Native token**: B²BTC (peg-style) + B² (governance/utility).

## Use cases

- **DeFi**: yield protocols, lending, AMMs.
- **Bitcoin staking-like products**: bridged BTC earns yield in
  B² ecosystem.
- **NFTs / Asset issuance**.

## Position

One of multiple "Bitcoin L2" projects competing for TVL in 2024-2025.
Notable but smaller than Stacks, RSK, Merlin in TVL terms (early
2026).

## Limitations

- **Federation trust** for current bridge.
- **EVM compatibility** but smaller dApp ecosystem.
- **Unclear path** to fully trustless bridging.
