Background and education
A formal educational history was not verified in the primary sources used for this profile. No institution or degree is inferred.
How the journey developed
Juels’s academic work covers cryptography, computer security and blockchain systems. His personal research site provides publications and information about his work at Cornell Tech.
Contribution to crypto
His research includes ways for smart contracts to obtain authenticated outside information. Cornell’s account of Town Crier describes an effort to connect on-chain programs with web data using a defined technical trust model.
Why the work matters
This research addresses a central limitation: a blockchain program cannot independently observe every event outside its ledger. Juels’s work is useful for understanding why oracle design is a security question. A feed’s authenticity, freshness and interpretation all matter, even when the contract consuming it executes exactly as written.
