Computing on Bitcoin #63
October 31, 2025 - Week 44

Welcome to this week’s edition of Computing on Bitcoin News, your curated briefing on the latest in Bitcoin infrastructure, protocols, and disputable computing.
Every week, we bring you technical updates and fresh ideas from teams building the future of trustless systems anchored in Bitcoin.
Let’s dive in.

01
TABConf Panel Highlights BitVM2 → BitVM3 Progress and Trustless Bridges

At TABConf 2025, leading engineers from BitVM, Citrea, Alpen Labs, and Babylon, including Robin Linus, discussed how garbled circuits and SNARK verification are shaping Bitcoin’s next generation of trustless bridges and vaults, highlighting progress from BitVM2 to BitVM3.

BitVM- Garbled Circuits, Trustless Bridges, Oh My! Building Bitcoin’s Next Generation Infrastructure

This session brings together leading researchers and engineers working on the cutting edge of Bitcoin verification, bridging, and off-chain computation. Together, they’ll unpack how garbled circuits and SNARK verification unlock new possibilities for bridges, vaults, and beyond, along with the hard engineering lessons from building these systems in the wild.

02
Fairgate's BitVMX Side Events in Buenos Aires

Fairgate is hosting two BitVMX-focused side events this November in Buenos Aires, aligned with LABITCONF and DEVCONNECT. These sessions will explore how BitVMX is powering real-world Bitcoin applications, offering builders, researchers, and curious devs a chance to connect directly with the Fairgate team and dive deeper into the evolving protocol ecosystem.

Event: Nov 9 / Palermo, Buenos Aires
🔗 Unleashing Bitcoin's Potential for Real-World Applications with BitVMX

As LABITCONF wraps up, a fitting close to the weekend.

Event: Nov 16 / Palermo, Buenos Aires
🔗 BitVMX, Garbled Circuits and Fairgate's Evolving Ecosystem of Protocols

Join us in this focused-event to explore how engineering practical solutions with BitVMX is shaping the future of disputable computing on Bitcoin.
As DEVCONNECT gets underway, start the pre-week warmup with a thorough yet relaxed update on everything BitVMX.

03
David Seroy Talks GLOCK and Rollup Verification on Built on Bitcoin

David Seroy, Ecosystem Lead at Alpen Labs, joined the Built on Bitcoin podcast to discuss GLOCK and how it advances Bitcoin rollups and trustless verification.

David Seroy, Ecosystem Lead at @AlpenLabs, to talk about his innovative work on Bitcoin.
We covered:
→ What GLOCK is and how it improves BitVM
→The future of Bitcoin rollups
→ Why Alpen is one of the most respected teams in Bitcoin

04
Fairgate’s FLEX presentation: Lightweight Fraud Proofs with Garbled Circuits

At BTC++ Istanbul, Ariel Futoransky presented FLEX (Fraud proofs with Lightweight Escrows for eXits), a new Fairgate protocol enabling on-demand security bonds leveraged by garbled circuits.

Ariel Futoransky, BTC++ Istanbul 2025: FLEX Presentation

Most existing optimistic bridges require large, permanent security bonds, creating high financial overhead and excluding smaller participants from operating.
FLEX (Fraud proofs with Lightweight Escrows for eXits) introduces a breakthrough approach to this problem.

05
Citrea Completes Audit Phase for ZK Rollup and BitVM Bridge

Citrea announced the completion of audits for both its ZK rollup and BitVM-based bridge, Clementine, marking a major milestone toward mainnet.

🔗 Citrea Fully Completes Its Audit Phase: A Major Step on the Road to Mainnet

By combining ZK rollup stack with a BitVM-based bridge, Citrea enables Bitcoin applications (₿apps) that are secured by Bitcoin and a bridge optimistically verified by the Bitcoin Network. Completing our audits is a crucial step on our road to mainnet that we want to share with the community

06
GOAT Network Blueprint Details BitVM2/3 Challenges and ZK Infrastructure

GOAT Network published its technical blueprint, detailing its architecture to achieve a true Bitcoin ZKRollup inheriting native Bitcoin security. The document outlines GOAT’s BitVM2 & BitVM3 challenge paths, Ziren workflow, decentralized sequencing, and optimistic computation mode.
