BOB Chain Overview

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

Key Features

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.

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.
