Main Objectives of @build_on_bob (BOB) 📌Increase Bitcoin's Scalability, Addressing Slow Transaction Speeds (7 Transactions/Second) and High Fees. @build_on_bob is a Hybrid Layer 2, utilizing Optimistic Rollup technology and integrating with OP Stack (similar to Optimism on Ethereum), while leveraging Bitcoin’s security through BitVM. Increase Transaction Speed: BOB processes transactions off-chain via Optimistic Rollup, compressing thousands of transactions into a single transaction recorded on the Bitcoin mainnet. Block Time: BOB achieves a 2-second block time (compared to Bitcoin’s 10 minutes), significantly speeding up transaction processing. Result: BOB can handle thousands of transactions per second, similar to Ethereum L2s, making it suitable for DeFi, NFT, and gaming applications. Reduce Transaction Fees: By processing transactions off-chain and only submitting compressed data to the Bitcoin mainnet, BOB reduces transaction costs by an estimated 99% compared to the Bitcoin mainnet. This makes microtransactions (e.g., small payments or DeFi interactions) feasible, with fees as low as a few cents instead of several USDT. BitVM Integration: BitVM (Bitcoin Virtual Machine) enables secure verification of L2 transactions without altering the Bitcoin protocol. This allows BOB to maintain Bitcoin’s security while increasing speed and reducing costs. BitVM2 (currently in testnet, expected to launch on mainnet) improves bridge efficiency, enabling BTC transfers to L2 without relying on third parties. Integration with OP Superchain: As a member of the OP Superchain, BOB leverages Optimism’s infrastructure to share liquidity and enhance interoperability with other L2 chains, reducing costs and improving performance. 📌Bring DeFi, NFTs, and Decentralized Applications (dApps) to Bitcoin Without Compromising Security or Decentralization. BOB is a Hybrid Layer 2, combining Bitcoin’s security with Ethereum’s programmability through the Ethereum Virtual Machine (EVM). Below are the specific mechanisms:EVM Compatibility: BOB supports EVM, enabling developers to use familiar tools like Solidity, Metamask, and Hardhat to build dApps, similar to Ethereum. This facilitates the deployment of DeFi applications (e.g., decentralized exchanges – DEX, lending protocols) and NFTs (e.g., Ordinals, Runes) with ease. Optimistic Rollup: BOB uses Optimistic Rollup (based on OP Stack) to process transactions off-chain, compressing thousands of transactions into a single transaction recorded on the Bitcoin mainnet. This: Increases Speed: Achieves a 2-second block time, compared to Bitcoin’s 10 minutes. Reduces Fees: Transaction fees are 99% lower than on the Bitcoin mainnet, suitable for DeFi and NFTs. Supports dApps: Enables complex applications like games, NFT marketplaces, or lending protocols. DeFi and NFT Ecosystem: BOB has integrated over 100 DeFi projects, including: Sovryn: A lending/borrowing protocol on Bitcoin. Velodrome: A DEX optimized for liquidity. Layerbank: A yield farming platform. Supports Runes, Ordinals, and BRC-20 – new token standards on Bitcoin, enabling the creation and trading of NFTs or other digital assets. Total Value Locked (TVL) is approximately $250M-$300M (as of July 2025), indicating strong ecosystem growth. 📌Create a Bridge Between Bitcoin and Ethereum, Allowing Users to Leverage Liquidity and Tools from Both Ecosystems. BOB is a Hybrid Layer 2 (L2), using Optimistic Rollup (based on OP Stack) and integrating BitVM to connect Bitcoin and Ethereum. EVM Compatibility: BOB supports the Ethereum Virtual Machine (EVM), enabling the deployment of Ethereum-like smart contracts on an L2 platform tied to Bitcoin. Users and developers can use familiar Ethereum tools like Metamask, Solidity, Hardhat, or Remix to interact with and build dApps on BOB. Trust-Minimized Bridge: BOB uses BitVM (Bitcoin Virtual Machine) and BitVM2 (currently in testnet, nearing mainnet launch) to create a secure bridge, allowing BTC to be transferred from the Bitcoin mainnet to BOB without relying on third parties. Mechanism: Users lock BTC on the Bitcoin mainnet, BitVM verifies the transaction and creates corresponding assets (wrapped BTC) on BOB. Wrapped BTC can be used in DeFi protocols (e.g., lending, swapping) or for trading NFTs (Runes, Ordinals) on BOB. When withdrawing, BitVM ensures BTC is securely unlocked to the user’s Bitcoin wallet. This reduces the risk of asset loss compared to traditional centralized bridges ( WBTC on Ethereum). #tenprotocol #superchain #bitvm
