Computing on Bitcoin #106
September 11, 2026 - Week 37
Welcome to a new edition of Computing on Bitcoin News.
From ongoing security research to new approaches for payments and Bitcoin programmability, the ecosystem keeps moving forward.
Here's our curated selection of this week's most relevant developments.
Let's dive in.
GOAT Network reported the first batch of results from its BitVM3 bug bounty program, which asked researchers to probe its trust-minimized Bitcoin bridge as an adversary would.

GOAT BitVM3 Bug Bounty: first batch results
When the BitVM3 Bug Bounty opened on August 18th, the request was to approach our trust-minimized Bitcoin bridge as an adversary would. The first batch of submissions has now completed full engineering review, and here are the results.
A new preprint introduces a typed-critique framework for evaluating Bitcoin on-chain poker proposals, clarifying BitVM’s role as an optimistic verifier and highlighting limitations around shuffling, Script, ZKPs, and MPC.

Before and After: A Typed-Critique Framework for Bitcoin On-Chain Poker Preprints
A 2026 preprint treating a social-media screenshot as the terminus of a linear 'Satoshi-to-Script-poker' story is examined under a typed evidence framework. Claims are classified by evidence grade. Twelve explicit weaknesses, eleven implicit, two inferred, and two extrapolated repairs are enumerated.
A new Fairgate article provides an in-depth comparison of Bit2, Lightning, Ark, RGB, and Base for agentic payments, examining tradeoffs across throughput, fees, confidentiality, liquidity requirements, and exit guarantees. Bit2 takes a different approach by avoiding liquidity lockups while targeting sub-second pre-confirmations and minimal Bitcoin L1 data usage.

Comparison between Bit2 and other Payment Networks for Agentic Payments
Bit2 is a new Layer-2 payment architecture based on client-side validation and cryptographic state compression.
This article compares Bit2 with several existing payment networks and Bitcoin Layer-2 designs—including the Lightning Network, Ark, RGB, and rollup architectures such as Base—across the metrics that matter most for agentic payments.
That wraps up this week's edition of Computing on Bitcoin News.
We'll be back next week with more developments from across the Bitcoin Computing ecosystem.
