Sui Network Integrates with Babylon Labs to Become a Bitcoin-Secured Network

The move positions Sui among the first blockchains to utilize Bitcoin's unparalleled security and $1.5 trillion liquidity pool

Sui Network, the latest generation layer 1 blockchain, is integrating with Babylon, a recently launched Bitcoin staking protocol, to join BTCfi and become a Bitcoin-Secured Network (BSN). This places Sui among the first blockchains to utilize Bitcoin’s unparalleled security and $1.5 trillion liquidity pool.

The integration, which was announced Thursday in a series of X (formerly Twitter) posts by Babylon, marks a significant milestone in the rapidly evolving ecosystem of Bitcoin DeFi (BTCfi).

"With Babylon Genesis going live, we're also excited to announce that Sui will be integrating with Babylon to become a Bitcoin-secured network," the post reads in part. "This will allow Sui to tap into Bitcoin's legendary security and massive liquidity—said to be in the $1.5 trillion range—in order to offer even more possibilities for developers and users."

"It's not just L2s—whole new ecosystems are going BTCfi. The next wave of dApps will be massively scalable and powered by the most secure blockchain in existence."

As part of its broader goal to build a "Bitcoin-secured decentralized world," Babylon is launching a protocol that transforms Bitcoin into a foundational layer for proof-of-stake security and liquidity in the new age DeFi ecosystem.

Unlike traditional proof-of-stake models, which rely on native token inflation to secure networks, Babylon's approach allows ecosystems like Sui to leverage Bitcoin staking for offering a more sustainable and secure alternative.

Earlier this week, it was announced that SatLayer, Babylon’s designated restaking partner, would be integrating with Sui to enable the network to tap into Bitcoin's liquidity. The partnership also aims to unlock opportunities for developers and enable users to interact with Bitcoin's nearly $2 trillion asset base.

The integration between Sui and Babylon is part of a broader trend where Bitcoin is evolving beyond its role as a digital gold standard.

Historically, Bitcoin's proof-of-work mechanism limited its use in DeFi, with most innovation occurring on layer-2 solutions like the Lightning Network. However, Babylon Labs is changing the narrative by enabling Bitcoin to secure entire programmable ecosystems through its staking protocols.

Validators participating in the Babylon ecosystem will be able to validate proof-of-stake chains and earn rewards for doing so, with potential delegations tapping into Bitcoin's $1 trillion market.
