Computing on Bitcoin #84
April 10, 2026 - Week 14

Welcome this week edition of Computing on Bitcoin News!
New ideas keep pushing the boundaries of what’s possible on the base layer and beyond.
Here’s a curated selection of the latest insights shaping the space.

01

zkSecurity published a session overview exploring zero-knowledge proofs on Bitcoin, including BitVM’s optimistic verification model and related techniques.

🔗 Archetype X zkSecurity - Proof Is in the Pudding: ZK on Bitcoin

Bitcoin's UTXO model and limited scripting language create unique challenges for verifying zero-knowledge proofs. In this session, we walk through the fundamental constraints of Bitcoin Script and then explore the creative approaches that have been developed to bring ZK verification to Bitcoin, from multi-party computation techniques to BitVM's optimistic verification paradigm.

02

Citrea outlined a roadmap toward post-quantum security, addressing execution, proving infrastructure, and its Bitcoin bridge design. The post references BitVM-style verification as part of adapting bridge security under post-quantum assumptions.

🔗 Post-Quantum Citrea

As a layer secured by Bitcoin, Citrea shares the concern of the broader Bitcoin community that quantum computers could eventually break the elliptic curve cryptography Bitcoin relies on. However, our preliminary analysis shows that Citrea is well-positioned to adapt to a post-quantum Bitcoin environment.

03

A new article by Sylvain Saurel discusses BitVM and its approach to enabling complex computation on Bitcoin without modifying the base layer.

🔗 BitVM: Computing on Bitcoin to Escape the Altcoin Bridge Trap.

The people who wrapped their Bitcoin learned a devastating, expensive lesson:
When you bridge your Bitcoin to an altcoin network, you no longer own Bitcoin. You own a corporate IOU on a centralized database, secured by nothing but the promises of tech bros and the mercy of hackers.

04

Fairgate published a post on Bit2, a client-side validation payment architecture for Bitcoin, describing a model for deterministic, high-throughput transactions without reliance on routing or sequencers, and contrasting it with Lightning and rollup-based approaches.

🔗 Why Client-Side Validation Will Power Agentic Commerce

Traditional payment networks were not designed for this environment. Most systems suffer from one or more structural limitations: capital must be locked to route payments, transaction data must be published to the base chain, routing failures are common, or centralized operators become regulatory choke points.

05

Geo Nicolaidis explores upcoming halvings, highlighting miner revenue, AI competition, and fee uncertainty, while noting BitVM as a potential future demand driver.

🔗 Issue 13: The Next Two Halvings

Even at $150,000 per bitcoin with $5 million in daily transaction fees, the network would be less secure per dollar of value stored than it is today at $67,800. The block subsidy halving outpaces price appreciation and fee growth combined in every scenario I can model. This issue lays out three scenarios for the 2028 and 2032 halvings, and stakes five specific, date-bound predictions on the result. If I’m wrong, I’ll say so in 2028.

Fairgate published a post on Bit2, a client-side validation payment architecture for Bitcoin, describing a model for deterministic, high-throughput transactions without reliance on routing or sequencers, and contrasting it with Lightning and rollup-based approaches.

🔗 Confidentiality in Commercial Agentic Transactions

A key property of this architecture is deterministic payment success. In traditional payment channel networks, such as the Lightning Network, payments may fail due to insufficient liquidity, routing fragmentation, or network topology constraints, and success probability often decreases as the payment amount increases. In contrast, Bit2 transactions succeed deterministically once accepted by the receiver: there is no routing process, no dependency on third-party liquidity, and no probabilistic execution.

Thanks for reading!
We’ll continue tracking the most relevant developments and sharing the signals that matter.
Stay tuned for more in the coming weeks.
