Sui Network, the 7th largest Proof-of-Stake protocol with a $1.2 billion TVL, has partnered with Babylon Labs to integrate its Bitcoin staking protocol. This collaboration marks Sui's transition into a Bitcoin-Secured Network, allowing Bitcoin holders to stake their assets to enhance the security of the Sui ecosystem without relinquishing custody. The integration taps into Bitcoin's $1.5 trillion market capitalization, aiming to leverage its security and liquidity to bolster Sui's operations. This move introduces a new economic model known as Bitcoin-backed scalability, which could enable the development of new decentralized applications and services on the Sui platform. Sui Network's expansion into Bitcoin DeFi is part of a broader strategy to enhance its ecosystem. Alongside this integration, Sui has also announced its availability on Ledger Live Mobile, enabling users to manage SUI tokens on-the-go, and has seen the launch of several projects on its platform, including LI.FI for cross-chain connectivity and Galxe for token distribution.
