BOB Chain Overview

BOB is a Hybrid Chain that combines Bitcoin's security with Ethereum's DeFi innovation.

Key Featuresโ€‹

  • Hybrid Zero-Knowledge Rollup: BOB has upgraded to Kailua, making it a hybrid zk rollup. By default, state proposals are made optimistically. When competing proposals arise, they're settled by validity proofs. Proposers can also submit validity proofs on-demand for fast withdrawals.
  • Fast Bitcoin Finality: All transactions are finalized by Bitcoin. This is achieved through Bitcoin checkpointing and BTC staking via Babylon's BSN architecture.
  • EVM Compatibility: Deploy and interact with EVM smart contracts. BOB uses the OP Stack with minimal modifications to the EVM - 100% compatibale with Base, Optimism and all other Superchains.
  • Low Fees: Significantly lower transaction costs than Bitcoin or Ethereum.
  • Native BTC Support: Use BTC directly in DeFi - with a single transaction through the power of Gateway and with full Bitcoin-security by BitVM.

Use Casesโ€‹

  • DeFi: Lending, borrowing, trading, and yield farming with BTC, stablecoins, ETH, and other assets.
  • NFTs: Mint and trade NFTs with Bitcoin security.
  • Payments: Fast, low-cost payments using BTC and stablecoins.
  • Staking: Earn yield on BTC and other assets.
