Everyone thinks BOB is just a Bitcoin L2. They’re wrong. When people hear @build_on_bob , they usually think of a Bitcoin L2. That’s only partly true - and here’s why. BOB is built on the OP Stack, giving it a full EVM environment with ETH as gas. All transaction batches are posted to Ethereum blobs, which technically makes BOB an Ethereum L2. Recently, the team introduced zk technology - called Kailua - to verify transaction batches. This reduced finality from 7 days to just a few hours. So far, nothing surprising—most of this is public knowledge. The real question is: why is BOB considered a Bitcoin L2? The Bridge That Started It One of BOB’s core components is BOB Gateway - intent-based bridge connecting Bitcoin and BOB via relayers and liquidity providers. It lets users move BTC into BOB and immediately deploy it into DeFi strategies. This gives BOB arguably the best DeFi UX on the market today. However, this gateway has trade-offs: centralization risks, security challenges, economic issues, and extra fees. It’s an interim solution, not the final vision. The Next Evolution: Phases 2 & 3 In the next development phases, BOB will align deeply with the Bitcoin network through two key innovations: 1. BitVM Bridge – first trustless BTC bridge between Bitcoin and BOB, developed with the @fiamma_labs . This cutting-edge tech allows seamless BTC deposits and withdrawals without trusted intermediaries. What is BitVM in details: 2. Bitcoin Security Service (BSN) from @babylonlabs_io - Gives BOB the same security level as Bitcoin by paying part of network fees for Babylon’s Shared Security Service. BOB’s state will be committed to Bitcoin via the Timestamp Protocol, making Bitcoin act as a DA layer. What is BSN in details: 2 DA Layers, 1 Secure Network Once live, BOB will have: Ethereum DA – via blobs (standard for OP Stack) Bitcoin DA – what @dom60808 calls a Fallback Layer This architecture (BitVM + BSN) unlocks a powerful advantage: BOB can build native, trustless bridges to virtually any network - with Bitcoin-level security. Imagine moving $SOL or $SUI in and out of BOB natively, without wrapping or centralized custody. Why This Matters The BOB team’s vision is ambitious: to become a decentralized CEX replacement - a high-security, Bitcoin-backed DeFi hub. In other words, BOB is not just “an L2.” It’s an EVM-compatible network, Bitcoin-based at its core, capable of bridging native assets across ecosystems. It will combine CEX-like liquidity and UX with the transparency and security of DeFi. ====================================== If you liked the research, plz like/retweet and follow to @Eugene_Bulltime And follow on strong visioners and analysts: @0xBreadguy @poopmandefi @TheDeFISaint @DoggfatherCrew @0xSalazar @DefiIgnas @Defi_Warhol @Moomsxxx @hmalviya9 @Mars_DeFi @rektdiomedes @eli5_defi @JayLovesPotato @Steve_4P @TheDeFinvestor @0xCheeezzyyyy @arndxt_xo @alpha_pls
