A proposed OTS-based model for building Bitcoin payment channels using hash-based One-Time Signatures instead of the revocation schemes used in Lightning today

RootstockLabs, and Fairgate launching UNION, a permissionless bridge connecting Bitcoin and Rootstock.

Fairgate Labs and Input Output co-hosted a technical workshop on Sep 25th in Buenos Aires, focused on advancing @Bitcoin-native computation.

WISCH's security is proven under standard cryptographic assumptions in the Universal Composability framework, ensuring strong protection and verifiable on-chain performance.

A pivotal moment has marked the future of decentralized finance: for the first time, a Bitcoin Ordinals has been transferred and recorded on the Cardano mainnet, thanks to the interoperability protocol BitVMX, developed by Fairgate

Ordinals can now bridge directly to the Cardano network. This new capability is part of a broader push by Input Output and Fairgate Labs under the BitVMX Alliance

According to Dave (@ItsDave_ADA), Input Output (IOG) and Fairgate Labs revealed major Bitcoin DeFi advancements at the Bitcoin 2025 Conference in Las Vegas on May 27, 2025. The update introduces decentralized finance functions such as lending and trustless swaps to Bitcoin, utilizing BitVMX technology.

RootstockLabs and Fairgate have formed an alliance to expand Bitcoin's utility using BitVMX, which also involves blockchain infrastructure engineering firm Input | Output (IO).

The BitVM and BitVMX protocols have long relied on inefficient one-time signature (OTS) schemes like Lamport and Winternitz for signing program inputs. These schemes exhibit significant storage overheads, hindering their practical application.
