According to online reports, the latest report from data analysis firm Messari pointed out that the Bitcoin DeFi Ecosystem (BTCFi) is experiencing dual improvements in security and cost advantages. As the core infrastructure, Bitcoin Layer2 network Rootstock is currently protected by 81% of Bitcoin's total hash rate (a 25 percentage point increase from February), with transaction fees reduced by 95% compared to the Bitcoin main network and 55% lower than the Ethereum network. The network supports smart contracts through an improved version of BitVMX programming language and integrates with the cross-chain protocol LayerZero to achieve multi-chain interoperability. The report emphasizes that with the addition of head mining pools such as Foundry and Spiderpool, the security of Rootstock transaction verification has been significantly enhanced. In 2025, the network will continue to attract developers through upgrades such as reducing fees by another 60%. Similar Bitcoin Layer2 projects such as Stacks and BOB will also accelerate the implementation of DeFi applications. Data shows that the current total lockdown volume of Bitcoin DeFi has exceeded US$1.5 billion, an increase of more than 300% compared with the beginning of the year.
