Computing on Bitcoin #79
March 06, 2026 - Week 10
Welcome to a new edition of Computing on Bitcoin News! The Bitcoin ecosystem continues to evolve at a remarkable pace, driven by ongoing research, engineering breakthroughs, and a growing community of builders exploring the protocol’s capabilities.
Each week brings new perspectives, technical discussions, and experiments that push the boundaries of what can be built on top of Bitcoin
Let's dive in.
A new episode of Bitcoin Rails features Robin Linus and Liam Eagen discussing the evolution of BitVM, including the integration of garbled circuits and the BitVM3 efficiency improvements.

In this episode of Bitcoin Rails, I sit down with Robin and Liam to discuss BitVM’s evolution following the integration of garbled circuits—an upgrade that improved efficiency by more than 1,000x over prior implementations.
A new article by Shinobi in Bitcoin Magazine revisits SegWit and Taproot, explaining how their design decisions enabled modern scaling systems such as Lightning, DLCs, and BitVM.

The Core Issue: Why Bitcoin Needed A Remodel With Segwit and Taproot
The former fundamentally changed the structure of Bitcoin transactions, and in the process Bitcoin blocks, to address inherent limitations of the previous transaction structure. The latter rearchitectured some aspects of Bitcoin’s scripting language, how complex scripts are structured and validated, and introduced a new scheme for creating cryptographic signatures.
Fairgate presented “WISCH: Efficient Data Signing via Correlated Signatures” at WTSC @ Financial Cryptography 2026.
The discussion highlighted strong interest in scalable, low-overhead data authentication for bitcoin protocols and decentralized systems.

The session covers the construction, security model, and practical implications of the Wisch protocol, a scalable data authentication system for bitcoin protocols and…
Alpen Labs outlines how BTC-backed credit can scale into onchain markets using Morpho V2 and standardized loan claims, highlighting BitVM-enabled bridges as key infrastructure for trust-minimized BTC collateral in scalable DeFi credit systems.

Size Matters: The Architecture of BTC Credit Markets
What's missing are expressive onchain loan markets and standardized, financeable claims. In mature systems, loans do not stop at origination. They trade, they get financed, and capital recycles. That recycling compresses rates and deepens liquidity. BTC-backed loans today largely end at origination.
DL Research interviews the OP_NET founders, who argue Bitcoin needs native L1 smart contracts to sustain its long-term security model. They contrast their Taproot-based design with approaches like BitVM and rollups.

X402: Two Approaches to Agent Payments
When people say “Coinbase x402” and “GOAT x402”, it sounds like two competing standards. But that’s a misframing.
There isn’t a Coinbase version of the protocol and a GOAT Network version of the protocol - x402 is an open, chain-agnostic payment primitive for the web.
We hope this selection of resources helps you stay informed and inspired as the ecosystem continues to grow.
Thanks for following along!
