Computing on Bitcoin #60
October 10, 2025 - Week 41
Welcome to this week’s edition of Computing on Bitcoin News, your weekly roundup of the tools, research, and innovations shaping Bitcoin’s programmable future.
Here’s a look at what’s new.
Diego Masini from Fairgate Labs published a deep dive into the BitVMX Protocol Builder, a Rust library for modeling Bitcoin protocols as directed acyclic graphs of pre-signed transactions. The article explains how this structure enables deterministic, auditable execution across complex multi-party protocols with timelocks, Taproot scripts, and MuSig2 aggregation, streamlining reproducible protocol design on Bitcoin.

BitVMX Protocol Builder Deep Dive
The Protocol Builder brings structure to Bitcoin protocol design, making complex systems reproducible and auditable under all conditions. Transactions and signatures can be prepared in advance and broadcast only when needed.
The BitVMX FORCE team joined BTC++ Berlin 2025 to showcase new advances in Bitcoin infrastructure. Sergio Lerner presented novel BitVMX-based payment channel designs enabling secure, watchtower-efficient operation with minimal storage and strong privacy guarantees. The team also hosted a workshop and hackathon, inviting developers to explore off-chain computation and protocol design on Bitcoin using BitVMX.

BitVMX FORCE at Bitcoin++ Berlin: Lightning the Path Forward in Bitcoin Infrastructure
At this year’s BTC++ Berlin, held from October 2–4, 2025, BitVMX FORCE joined the community to present new ideas and working code for lighting and payment channels, all compatible with Bitcoin’s consensus rules.
A new article by the BOB Network explores how Bitcoin staking is becoming possible through innovations like Babylon’s trustless time-lock scripts, Liquid Staking Tokens (LSTs), and BitVM-powered bridges.

Bitcoin Staking - The Ultimate Guide To Making Yield on Your BTC
Its new testnet uses a distributed system of GPU-powered nodes that process blocks, aggregation, and Groth16 proofs, in parallel. According to GOAT, this setup eliminates bottlenecks and allows for near-instant withdrawals.
As part as the BitVMX open source stack initiative, two new core components were made publicly available: Message Broker and Operator Communication Library. With these modules now open source, developers can directly integrate low-latency, identity-bound messaging into their own Bitcoin-native systems.

BitVMX’s Open Source Stack keeps expanding: Message Broker & Operator Communication Library
These libraries enable secure, authenticated communication between operators, laying the foundation for multi-operator coordination in off-chain protocols, dispute systems, or shared execution networks. With these modules now open source, developers can directly integrate low-latency, identity-bound messaging into their own Bitcoin-native systems.
Goat Network’s Kevin Liu shared why Bitcoin’s future depends on native Layer 2s. In a recent AMA, he explained how Goat’s zkVM and BitVM2 integration enable scalable computation anchored to Bitcoin security.

Bitcoin needs L2s to scale — AMA recap with Goat Network
The journey began in early 2023, when Goat’s research team started experimenting with zero-knowledge computation. By the end of 2024, their zkVM was live on mainnet, proving blocks in real time. For Bitcoin and its intentionally limited Script language, this was a breakthrough. Complex computation had to move offchain, yet there was no easy way to bring results back securely.
A new analysis argues that Bitcoin’s real revolution isn’t in its price, but in its code. BitVM2 and projects are pushing Bitcoin toward a new era of native smart contracts, trust-minimized bridges, and BTC-based DeFi built directly on-chain.

Forget The Price — Bitcoin’s True Revolution Is Being Written In Code
Bitcoin’s new all-time high (ATH) is dominating the timeline, but it’s not the real story. Under the surface of price charts and speculation, a quiet technological revolution is taking shape and could redefine BTC’s utility in the ecosystem. In an X post, High Tower revealed the real ATH is in the code, and the movement centers on BitVM2, an evolution of the original BitVM model.
Thanks for tuning in to this week’s Computing on Bitcoin News.
We’ll return next Friday with more insights, tools, and stories from across the decentralized stack.
