Brink grantee @conduition_io presented on the state of post-quantum Bitcoin research:
- Post-quantum output types
- Quantum canaries and tripwires
- Freezing, ignoring, or rate-limiting Satoshi-era coins
- Rescue protocols
- Hash-based, lattice, isogeny signature schemes
- Q&A

Eugene (@bitcoinbrink grantee) has been working on incremental snapshots for fuzzamoto and just published a blog post on it: crypt-iq.github.io/2026/08/0…
We are excited to announce that Martin Zumsande (@lightlike1) has (re)joined Brink to continue his work on Bitcoin Core including P2P networking, validation, testing, and review!
Martin will focus on researching address relay propagation, improving block download reliability, closing a privacy leak in wallet transaction rebroadcast, and expanding validation fuzz testing, in addition to continued code review.

Thank you @ColeMacro and @Strive for supporting Brink and open source Bitcoin development!

Is it possible to get a virtual machine to halt at a precise instruction count? Answering this question took some time, but I think the answer is yes (with minimal single stepping).
Niklas (@dergoegge) outlines an approach and a solution, bedrock, for this problem of determinism.
He focuses on the challenge of emulating time and pausing a VM at an exact instruction count, something CPUs aren't designed to do.

The result is an open source tool, bedrock: an experimental hypervisor purpose-built for deterministic software testing.

Toby Sharp (@bitcoindudebro) joined Brink engineers to present Hornet, an executable specification for Bitcoin consensus:
- Code is the spec
- Hornet & kernel
- Block validity rules
- A new UTXO database
- A consensus DSL
- Differential and adversarial testing
- Q&A

Brink has always funded remote engineers, since our inception.
Our London office is there for those who want an in-person space to collaborate, but it's always been optional.
In fact, most of the engineers we've funded over the years have worked remotely. The mix shifts over time. Right now it's 5 in office and 4 remote.
Wherever you are and whatever lets you do your best work on Bitcoin is what we're here to support.

I'm hyped to announce that I am Brink's first-ever grantee to focus on Bitcoin's post-quantum crypto R&D 🎉🤓 brink.dev/blog/2026/06/01/co… This funding will help me focus full-time as I collaborate with @blksresearch to draft a balanced, efficient, and secure PQ signature upgrade.
We are excited to announce that conduition (@conduition_io) has joined Brink as cryptographic engineer working on post-quantum cryptographic research and implementation!
We are excited to announce that conduition (@conduition_io) has joined Brink as cryptographic engineer working on post-quantum cryptographic research and implementation!
Conduition’s work will focus on three areas: driving the SHRINCS protocol toward a draft BIP, exploring commit/reveal protocols, and advancing research and education around isogeny-based cryptography in Bitcoin.
Welcome conduition!
