Computing on Bitcoin #97
July 10, 2026 - Week 28

Welcome to a new edition of Computing on Bitcoin News!
Here’s a quick roundup of the latest research, technical discussions, and ecosystem developments from across the Bitcoin space.

Let's dive in

01

The GOAT Research team published an technical note introducing Deferred Binding, an extension to BABE that supports dynamic public inputs in BitVM3.

Groth16 is a widely-used zero-knowledge proof system. In standard BitVM2, verifying a Groth16 proof requires executing the full verifier inside a Bitcoin Disprove script — evaluating several elliptic-curve pairings over BN254. The resulting script is several hundred kilobytes and far exceeds Bitcoin's script-size limits.

02

Martin Hiesboeck shared an overview of Bitcoin’s technical roadmap, highlighting BitVM, covenants, Lightning upgrades, client-side validation, and modular Layer 2 and Layer 3 architectures as key scaling directions.

03

GOAT Network published an overview of the GOAT Stack, outlining its Bitcoin settlement architecture, BitVM2/BitVM3-based bridge, zkEVM execution layer, and agent-focused application stack for Bitcoin-native programmable finance.

🔗 The GOAT Stack

Most of crypto starts from the application and works down, hoping the foundation holds. We started from the foundation. The premise of GOAT Network is that the bottom of any financial stack - the layer where a balance becomes a fact that no operator, council, or issuer can reverse - should be the most neutral and most attack-costly ledger that exists.

04

A new video explains the BitVM3 bridge peg-in process, covering Bitcoin's covenant limitations, the deposit transaction design, and the mechanisms used to enable trust-minimized deposits into the bridge.
