STROBE: Streaming Threshold Random Beacons Appearing today at AFT 2023. It's all about how to flip fair coins robustly and verifiably in public - without needing costly consensus algorithms or zero-knowledge proofs. drops.dagstuhl.de/opus/volltexte…

As usual it is really cool to do a podcast with @AnnaRRose .... zeroknowledge.fm/295-2/

Interesting abstract, scary coverage. Why does it cost me $32 to read a research paper likely funded by US taxes? nature.com/articles/s4159…

Spent my youth adding semicolons to make C happy. Spending my dotage removing semicolons to make Rust happy. Definitely getting rustier with age.

Hello, today we are disclosing two critical trusted-party vulnerabilities in the LayerZero smart contracts. These issues allow the LayerZero team to completely bypass the Oracle and Relayer for most applications (including stargate). prestwich.substack.com/p/zero-validat…

1.2 million gigabots per second - Kevin Bowers

Incredible presentation by Kevin Bowers on Firedancer, HPC in trading environments and Jump’s motivations in building crypto infrastructure. youtu.be/oNRSeEATOFw

8/ We’re excited to contribute to a ZK future! Reach out to @rahulmaganti_, @nickraystalder, @0x0ece, and @donbeaver if you want to chat about hardware acceleration and ZKs.

1/ Accelerating Multi-scalar Multiplications (MSMs) is essential to making ZKPs fast and cheap. We’re excited to share a radical improvement in MSM hardware acceleration: jumpcrypto.com/accelerating-m… CycloneMSM: A Novel Architecture for Accelerating MSMs on FPGA 🧵👇

Fantastic result from the @jump_ team (and @donbeaver ?) 👏 hardware is a game-changer for ZKPs.

@CouteauGeoffroy @badcryptobitch The protocol in STOC 1996 took the first step, with an interactive protocol. Non-interactivity was always a desire, and an obvious one at that. “Anticipated,” yes. Sadly, LWE wasn’t yet in the crypto toolkit. So no, I didn’t achieve silent PCG, but the idea dates to 1995.

@CouteauGeoffroy @badcryptobitch The STOC 1996 paper coins the term “Correlated Pseudorandomness” in reference to PRGs. Here’s the grail I anticipated and set out to achieve in 1995. Without interacting - as though each had a fancy PRG - they locally expand their correlated inputs to longer correlated values.

Been trying to grasp the concept of PCGs (Pseudorandom Correlation Generators) recently and I still don't get them. However, I may have a few interesting spots where we can apply them to make certain cryptography areas more practical. 🧵

History Generation: a new property for decentralized randomness. Unlike DRAND and co, you only need the latest beacon to produce the whole history down to genesis, favoring light client constructions, i.e. for beacon streams in UDP games (lost packets). eprint.iacr.org/2021/1643

@BenCoxMusic I feel like I know less and less over time, so definitely converging on zero knowledge universe. It’s just also being done purposefully in the ledger world.
