This a curated list of projects I no longer work on that I am proud of and/or display my research and product interests. A less curated but more complete list can be found here: All past projects
2024
March ‘24 to June ‘24: Signature Singularity Residency Organizer
- Alongside yush, organized a residency bringing teams taking useful signed data and wrapping it in ZK proofs for succinctness (on-chain use cases), ownership (raw signature never revealed to server), and selective disclosure (only revealing relevant info)
- Supported primarily by PSE
- Demo day here: https://demo.sigsing.com, and full list of projects here: https://lu.ma/k4t26qch
January ‘24 to March ‘24: Denver ZK Quests
- Launched an NFC activation for ETHDenver attendees by chipping all entrance badges
- Experience focused on loyalty/engagement — rewarding participants who could make ZKPs of deeper engagement with certain brands or events with better prizes
- ZKPs were wrapped as “quests” that attendees could finish
- Gave out 12,000 badges for 50,000 total taps and 3,000 quests finished
2023
August ‘23 to January ‘24: Jubmoji
- Funded by PSE, project & design led by Rachel, technology led by me
- 2023 activation at Zu/Devconnect using NFC cards that produce unique Baby jubjub signatures upon tap
- Privately digitize In-person cryptography experiences into VIP data
April ‘23 to July ‘23: ZuStamps
- Funded by Org 0xPARC, led by me and collaborated with Rachel & Althea
- Part of a long line of In-person cryptography projects I have done
- First deployment of signature-producing NFC chips for ZK applications
- Featured on Vitalik’s blog here
September ‘22 to February ‘23: WebAuthn and ZK research
- Funded by Personae Labs, led by me and collaborated with Aayush and Richard
- Culminated in heyauthn!
- Demo using WebAuthn/Passkeys to power Semaphore identities
- Later upstreamed to main Semaphore repo by Richard!
- Used NFC CMAC chips to create Semaphore groups, first documented use of NFC for ZK
- Posted to a ZK IAP class Discord channel
- Supported work to create ZK circuits to prove knowledge of valid WebAuthn signature
2022
August ‘22 to January ‘23: Speeding up client-side zk-ECDSA
- Funded by Personae Labs, collaborated with Dan Tehrani
- Culminated in spartan-ecdsa, developed after I learned about the secp-secq cycle
- I focused on Halo2-IPA combined with ECFFT, unfortunately this was quite difficult and Dan’s work with Spartan ended up being successful
- efficient-ecdsa research and implementation in heyanoun
March ‘22 to November ‘22: heyanon!
- Funded by Org 0xPARC and Personae Labs, collaborated with Lakshman Sankar
- Anon twitter posting with ETH reputation
- ECDSA proving was way too slow for this to be useful/fun, I was laser focused on improving that in later projects
2021 and before
September ‘20 to June ‘21: Adversarial learning & image model research
- Researcher in Madry Lab, initially investigating adversarial learning as an ML application of my cryptography/security interests
- Researched effect of “hidden augmentations” to learning models on ImageNet performance compared to actual architectural differences
- Researched sample complexity of OOD performance for SoTA ImageNet models, as a follow-up to “Do Adversarially Robust ImageNet Models Transfer Better?”
December ‘18 to April ‘19: Blockchain quantitative research
- Job at a (now defunct, lol) crypto hedge fund called Virgil Capital
- Researched underlying cryptoeconomics of prominent DeFi platforms like MakerDAO and Compound to develop trading strategies
January ‘17 to August ‘18: Authenticated data structures research
- Member of Devadas Lab at MIT, advised by Alin Tomescu
- Researched and developed efficient append-only authenticated dictionaries, published in ACM CCS ‘19
- Applications to certificate authorities and public-key directories
- Clever combination of KZG polynomial commitments and binary tree structures
