TL;DR
- Sui will integrate Babylon’s Bitcoin staking protocol and operate as a Bitcoin Secured Network in Phase 3 of the expansion plan.
- The integration allows BTC staking without bridges or custodians.
- Babylon will apply its protocol over Sui’s Mysticeti consensus, reinforcing its modular, multi-network approach to Proof-of-Stake.
Sui announced that it will integrate the Bitcoin staking protocol developed by Babylon and will begin operating as a Bitcoin Secured Network (BSN).
This integration is part of Phase 3 of Babylon’s expansion plan, scheduled to launch before the end of the year. The decision marks a highly relevant shift in how Proof-of-Stake networks can benefit from Bitcoin’s security and liquidity without compromising fund custody.
How Will the Integration Work?
Babylon’s protocol enables users to stake BTC without handing over control to third parties, and without the need for bridges or wrapped assets. Through this structure, Bitcoin users can directly contribute to securing the Sui network and earn rewards without moving 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 Seeks to Channel Bitcoin Capital
Sui, currently ranked as the seventh-largest Proof-of-Stake network according to CoinGecko, is adopting this model following a clear trend: more and more projects are seeking 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 yields and support other decentralized infrastructures. For Bitcoin users, this represents a way to activate a historically passive asset without giving up self-custody.
Babylon has already integrated its technology with other consensus architectures like Cosmos, OP Stack, and Arbitrum. In the case of Sui, it will apply its protocol over the Mysticeti mechanism, a solution that uses DAG-based parallel block production and offers high processing capacity. This adaptation confirms the flexibility of Babylon’s model and its aim to provide modular security to different types of Proof-of-Stake networks
