Sui has announced that it integrates Babylon’s Bitcoin staking protocol and begins operating as a Bitcoin Secured Network (BSN). The integration is part of Phase 3 of Babylon’s expansion plan, scheduled to launch before the end of the year. The move marks a significant shift in how Proof-of-Stake networks can benefit from Bitcoin’s security and liquidity without compromising the custody of funds.
The Babylon protocol allows users to participate in Bitcoin staking without handing over control to a third party or using bridges or wrapped assets. With this structure, Bitcoin users can directly contribute to the security of the Sui network and earn rewards without taking their funds off the main chain. This integration creates an operational link between both networks and opens the door to new decentralized applications and services that leverage Bitcoin’s security and Sui’s scalability.
Sui, currently ranked seventh among Proof-of-Stake networks by CoinGecko, is adopting this model, following a clear trend: more projects are looking to expand Bitcoin’s utility beyond its role as a store of value. The goal is to channel BTC capital into programmable environments that generate yield and support other decentralized infrastructures. For Bitcoin users, this represents a way to activate a historically passive asset without giving up custody themselves.
