Presenting WISCH: Efficient Data Signing via Correlated Signatures today at WTSC @IFCA_Conference ’26. The session covers the construction, security model, and practical implications of the Wisch protocol, a scalable data authentication system for bitcoin protocols and decentralized systems. Paper: fairgate.io/publication/25…

As we prepare for FC’26, here’s why WISCH matters. As protocols grow more sophisticated, on-chain data publication becomes a primary cost driver, particularly in Bitcoin-based constructions, where protocol data and its signatures contribute directly to transaction weight. WISCH leverages correlated signatures to move most of the work off-chain, significantly reducing final on-chain protocol fees. We’ll present the full construction at WTSC @IFCA_Conference '26. Meanwhile, you can check the WISCH paper here: fairgate.io/publication/25…

We're thrilled to share that our paper “Efficient Data Signing via Correlated Signatures (WISCH)” will be presented at WTSC @IFCA_Conference! WISCH introduces a new protocol for efficient data authentication based on correlated signatures, enabling: • Reduced on-chain footprint • Reduced storage and communication requirements • Strong cryptographic guarantees This work contributes to advancing practical cryptography for advanced bitcoin protocols.

Beyond research, Sergio also participated in Bitcoin Rails Podcast, where together with @isabelfoxenduke they discussed Bitcoin scaling, BitVM-style designs, and where computation on Bitcoin is heading. Check it here: youtube.com/watch?v=JYnh87…

2026 started strong for Fairgate. We kicked off the year by publishing OHMG, a new paper exploring novel approaches for scalable Bitcoin verification and computation. fairgate.io/publication/36…

The original proposal of "sidechains" to Bitcoin by Gregory Maxwell @adam3us @TheBlueMatt and others proposed a new opcode to enable trustless sidechain pegging... but the idea was quickly dropped after the release of the canonical paper. @rootstock_io creator @SDLerner comments on why this architecture was never pushed forward and how the political environment for making changes to Bitcoin has changed since that era, now over a decade ago.

Something not discussed often enough is that incentives to execute a 51% attack goes up substantially with bridging "honeypots" created by Layer 2s. According to @RootstockLabs creator and @FairGateLabs CTO @SDLerner, this was likely a reason early discussions of upgrading Bitcoin to faciliate trustless bridges (eg via the canonical sidechains paper by @adam3us and others) were not pursued over a decade. To be fair, miner centralization was a much greater risk at that time—but remains a risk today, especially as the Bitcoin block subsidy declines. Full episode in the comments 👇
