Brink

We support open source Bitcoin protocol developers

[Mike Schmidt @bitschmidty]

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 🎉🤓 https://t.co/3y4Zcp077g This funding will help me focus full-time as I collaborate with @blksresearch to draft a balanced, efficient, and secure PQ signature upgrade.

[Brink @bitcoinbrink]

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!

We are excited to announce that conduition (@conduition_io) has joined Brink as cryptographic engineer working on post-quantum cryptographic research and implementation!

[Brink @bitcoinbrink]

Both engineers made meaningful contributions to Fuzzamoto. Their work extended protocol support, improved benchmarking infrastructure, scaled coverage analysis, and broadened target coverage for the testing platform.

Thank you Dongjia and Stratos for your contributions!

[Brink @bitcoinbrink]

Two Brink research interns, Dongjia Zhang and Stratos, recently wrapped up their 3 months of work on fuzz testing for Bitcoin Core.

Under the guidance of Niklas Gögge (@dergoegge), each conducted independent research & experimentation on Fuzzamoto...

Stratos is a vulnerability researcher and approached Bitcoin Core security from a systems and protocol security perspective.

"The State Of Bitcoin Core" by @bitschmidty of @bitcoinbrink

"There's a paradox in Bitcoin Core in that... the code is transparent, but understanding of the code is scattered in IRC and other places"

100 slides on the who & what of the @bitcoincoreorg project.

“Im looking forward to continuing to support current and upcoming privacy proposals with a strong focus on code review in general and occasional unexpected side journeys such as implementing the first SwiftSync PoC. Thanks to Brink for supporting me throughout this journey” 🧡

[Brink @bitcoinbrink]

This month, we're celebrating five years of Sebastian Falbesoner (@theStack) working on Bitcoin Core and libsecp256k1 at Brink.

Sebastian started with often unglamorous test work, steadily widening his scope, and eventually stepping up to steward impactful privacy proposals…

[Brink @bitcoinbrink]

Sebastian’s next priorities are getting silent payments merged into libsecp256k1, activating the DLEQ module, reviewing BIP54 (the Consensus Cleanup), working on FROST threshold signatures and helping with the ongoing effort to remove libevent as a Bitcoin Core dependency.
