UTXO Stack and Babylon Collaborate to Launch the First Native Bitcoin UTXO Scaling Solution

UTXO Stack will launch the first Bitcoin L2 scaling solution based on the native UTXO model with Babylon. UTXO Stack will launch a PoS DA chain to support challenge proofs for L2 built on UTXO Stack. Babylon will serve as a security provider to support PoS L2 and PoS DA chains.

The solution adopts the UTXO model isomorphic to Bitcoin, and ensures security through two mechanisms: user-staked RGB++ tokens and Babylon's remote BTC staking. It aims to provide a high-performance, low-fee environment that supports Turing-complete smart contracts and allows users to pay fees directly with BTC wallets and BTC.

UTXO Stack plans to launch its testnet in the third quarter of this year, supporting staking and re-staking of assets such as BTC and CKB. This collaboration is expected to bring efficient, low-cost, scalable and secure native L2 solutions to the Bitcoin ecosystem, further enriching Bitcoin's application scenarios.
