Brink is Now Funding My Research

I can afford breakfast now!

If we someday want to replace quantum-vulnerable ECC, we want something compact, flexible and fast. Isogenies seem like the only candidate so far: 66 byte pubkeys, 148 byte sigs. I wrote a thing explaining isogenies, aimed at people who already know ECC.

Do you love bitcoin smart contracts? Sick of constantly renewing your DLCs with on-chain transactions? Wouldn't you prefer your adorable lil' smart contract to live forever? Now it can.

Discreet Log Contract Factories

Bitcoin smart contracts which can be extended infinitely and interrupted at any time.

What's amazing to me is that despite crossing into six figures of USD per bitcoin, median on-chain transaction fees are still at single-digit sats-per-byte rates.

$100k Bitcoin guys and girls. Inevitability makes it no less awe inspiring. Clever purposeful dev teams are the reason why it happened. When people ask me why i'm so confident in Bitcoin, I say it's because i know how many brilliant minds are actively working out the kinks and making Bitcoin practical. With so much 🧠 power we can't help but succeed at least a little bit. Anyways, tick tock next block, I'll see you tomorrow internet.

"Sell me this preimage." You can verifiably purchase the solution to any NP-Complete problem using Bitcoin (and Lightning), combined with zero-knowledge proofs. - Buy the solution to a sudoku puzzle - Buy the prime factors of an RSA key - Bridge HTLCs with PTLCs - Buy a valid proof-of-work - and more...

Verifiably Buy Solutions to NP Problems with Bitcoin

Using zero-knowledge proofs to convert a standard HTLC into the purchase of a secret with arbitrary properties.

I went on a deep dive into post-quantum hash-based signatures and tried to apply them to bitcoin. At the end of the article I propose a way to insure today's Bitcoin wallets with a quantum-resistant fallback key, without any consensus changes needed.

Hash-Based Signature Schemes for Post-Quantum Bitcoin

All safe roads once were wild.

I just found out... there's a NIP for publishing discreet log contract messages on Nostr?? This is a crucial step for DLCs on Bitcoin. The present bottleneck for DLCs seems to be: How do I become an oracle? How do I find trustworthy oracles? NIP-88 would let us build apps which answer those questions.

NIP-88: Discreet Log Contracts over Nostr by benthecarman · Pull Request #919 · nostr-protocol/nips

Still pretty heavy WIP but wanted to get it out there for other people's feedback in nostr and DLC communities. Will be implementing this in: Mutin...

Combine this with ECash DLCs and we could have scalable, instant, completely private micro-contracts, which are discovered over Nostr and settled in ECash.

NUT for DLC execution by conduition · Pull Request #128 · cashubtc/nuts

Depends on #127 Closes #122 Adds a NUT which enables DLC execution using a cashu mint as a blind intermediary. Based on this proposal.

But even if you don't like ECash, this NIP is still incredibly important. Kudos @benthecarman

Had an idea for scaling submarine swaps into a multi-party protocol, and got some interesting results. Have a look:

The cull we're seeing in the past couple weeks is just the beginning, but it's a good sign: They're pushing back because we're gaining ground. If you want to run a privacy business, i see 3 choices: - Decentralize your business (no single PoF) - Mask yourself (build pseudonymously) - Comply (by KYCing)

@craigraw How do you feel working on Sparrow Wallet, now that we're seeing the US government prosecute the Samourai devs?
