Babylon, a project aimed at bringing Bitcoin security to PoS networks and DApps, plans to launch a Bitcoin pledge agreement, which supports Bitcoin holders to improve the security of PoS chains and DApps and obtain benefits by pledging Bitcoins, and PoS chains and DApps can choose to access the economic security mechanism supported by Bitcoin. The protocol does not require cross-chain, anchoring or any third-party hosting, and can be seamlessly deployed on the existing Bitcoin network. In addition, Babylon will hold a "Bitcoin Staking Litepaper Reveal" event at 6:00 PST on July 13th, and co-founder David Tse will give a detailed introduction.
