Verifying ZK proofs on Bitcoin is awkward and tricky, but it is possible! In Session 09 of Proof is in the Pudding, @cryptodavidw walks through the creative cryptographic workarounds that have emerged in response to Bitcoin’s design constraints ⌛️ TIMESTAMPS 00:00 Intro 00:33 UTXO Model vs Account Model 03:08 Bitcoin Script Limitations 04:39 Verifying ZK Proofs in Bitcoin Script 06:39 ZK Bitcoin, OP_CAT 08:51 BitVM and Optimistic Verification 12:05 Timelocks and Forcing Progress 13:57 Statelessness Problem 15:06 Lamport Signatures for State 19:41 Taproot 21:29 Simulated Covenants 26:20 BitVM Fraud Proof 33:44 BitVM 3, Hashlocks, and Garbled Circuits 47:01 Cut-and-Choose Security 48:53 Witness Encryption (BABE) Proof is in the Pudding is produced in collaboration with @zksecurityXYZ

Octane is #1 on the @code4rena yearly leaderboard – the first time Al has ever held top spot. We're excited to bring the leading Al-native security analysis to more clients and contests.

RWAs aren’t just about putting assets onchain The speakers at our RWA Research Day dove into all the details that actually matter You can find the talks below from: + @YuvalRooz of @digitalasset & @CantonNetwork + @hocryptogu of @tenbinlabs + @CharlieYouAI of @RWA_xyz

“We can’t solely bring asset exposure. We have to bring the habitat around the assets onchain.” @hocryptogu of @tenbinlabs argues that simply wrapping assets still comes up short and explains what Tenbin is doing to bring market structure onchain From our RWA Research Day

“Things that were recorded yesterday are being capitalized today, and they’ll be composable tomorrow.” @CharlieYouAI of @RWA_xyz talks the three phases of tokenization and how RWAs evolve into fully onchain financial markets From our RWA Research Day

“Without privacy, we’re just going to stay a crypto playground.” @YuvalRooz of @digitalasset & @CantonNetwork explains how crypto’s lack of privacy and misaligned incentives remain major blockers to real institutional adoption From our RWA Research Day

"As each PET evolves, their pros and cons start to overlap. Well-rounded TEEs pick up distributed trust properties that used to be MPC's domain. FHE gets cheaper and more expressive. MPC gets faster." From @oddhash in the final installment of his privacy tech trilogy

Private shared state might be our best shot at fixing the internet's privacy problem And TACEO just brought it to life

Crypto's privacy tech today is like locks from the 18th century, where very locksmith was competing to make the most elaborate design possible. We need a standard pin-tumbler that anybody can use or repair. A Universal Cryptographic Protocol (UCP).

Introducing Chaotic Good 👺 a new show from Archetype We got @dberenzon and @thatdegenvc to test the format in ep0 by debating: + Polymarket + Claude + Elon + 7-Eleven and more... More Chaotic Good coming soon

We're hosting an unconference with @TACEO_IO later this month! If you're coming to NYC for @blockworksDAS and working on the hardest problems in onchain payments, then this is for you Please reach out to an Archetype or TACEO team member for an invite!

We'll be at @blockworksDAS in NYC later this month! Together with @archetypevc, we're hosting a closed-door unconference on what's actually hard about onchain payments >> compliance, privacy, and the constraints that emerge in production. No panels. No pitches. Just the hardest problems in the room. DM us or reach out to the Archetype team for an invite!

"At its core, transparency isn't just a design choice. It is the structural evolution required to onboard the next billion users."

"As the garbler, I generate a bunch of garblings." - @cryptodavidw at @archetypevc x @zksecurityXYZ's proof in the pudding 09 real quote btw

Following several conversations with founders seeking to reconcile today's strange fundraising market, sharing some candid thoughts on why things feel so paradoxical and how to better play the game on the table
