rust + cryptography · building multiparty computation @ArciumHQ prev. physics @ ETH Zurich 🇬🇷🇨🇭🏳️🌈
a powerful use case arcium enables: permissionless prediction markets. the problem? resolving outcomes without bias. most markets today rely on optimistic oracles or public voting - both easy to manipulate, as we've seen. early voters sway outcomes, others follow to avoid stake…
The program for the Simons MPC workshop is now available: simons.berkeley.edu/workshops/secu… See you there!
Can cryptography solve the problem of MEV? One approach is an encrypted mempool, where users broadcast encrypted transactions that are only revealed after they are sequenced. Hence, a consensus protocol would have to commit to a transaction ordering blindly, seemingly…
We updated our paper on Fiat-Shamir! We now take a closer look at the gap between what symmetric cryptography has focused on for over 10 years (indifferentiability) and what is actually needed for the soundness of ZKPs and SNARKs (something stronger!). eprint.iacr.org/2025/536
One of our portfolio companies quietly making significant progress behind the scenes is @ArciumHQ. A recent announcement from them that deserves far more attention: they've introduced a completely new token standard on Solana called Confidential SPL Tokens. These tokens enable…
Privacy in Crypto Is Getting an Upgrade New privacy technologies are emerging: MPC, FHE, TEEs, and zkTLS. Each tackles privacy from a different angle — and major projects are building with them now. Here’s how these technologies work — and where they’re going👇 ~~ Analysis by…
Classic zk-washing: "Our system is private-the proof reveals nothing-trust us". Meanwhile, the proofs are coming from *inside* their servers. So they see everything. I've seen too many claims of private DEXs, private payments, and private identity schemes where this happens.
Privacy Perps DEX thread. Tldr: *The only* viable solution uses ZK, encryption + central operator. Scales to 200M users, easily Subtext: I’m *the* expert on this shit (see Fine Print). ALPHA: at THE END >>

[New] Multiparty Homomorphic Secret Sharing and More from LPN and MQ (Geoffroy Couteau and Naman Kumar and Xiaxi Ye) ia.cr/2025/966
one of the holy grails of crypto would be to replicate CEX privacy and compliance but with blockchains’ decentralization everyday users don’t want to go fully onchain because their entire financial life becomes public, and institutions don’t know how to make blockchain platforms…
Privacy 2.0 Market Map (v2) The Privacy 2.0 landscape can be split into 3 key PETs, enabling private shared state: - FHE (Fully Homomorphic Encryption) - MPC (Multi-Party Computation) - TEEs (Trusted Execution Environments) If you know of any other projects that belong in…
