Rootstock is the earliest and longest-running Layer 2 for Bitcoin, focusing on bringing programmability to BTC since 2018 without sacrificing security. By combining mining to inherit Bitcoin's hash power, using BTC as the native asset and gas, and returning transaction fees to miners, Rootstock has become the chain closest to Bitcoin's native DeFi. Here, BTC can participate in DeFi without needing to be sold, and EVM compatibility allows developers to migrate seamlessly, with established protocols like Sushi and Uniswap already implemented. Recently, Rootstock completed a 60% reduction in gas fees, the network continues to upgrade, and both TVL and revenue are hitting new highs, with the ecosystem entering an acceleration phase. If you're interested in Bitcoin DeFi, the long-term use case and value capture of BTC, Rootstock is worth your serious study. To stay updated, follow the Chinese updates @RootstockCN!
