privacy (Why) Bringing Privacy to Smart Contracts is Non-trivial Private transactions are basically a solved problem for the consumer (although some challenges still remain for researchers). If we want to transfer cryptocurrency without revealing our balance or the transfer amount, we have acceptable options available like Zcash and Monero. The same cannot be said for private decentralized applications or
An Intro to Fully Homomorphic Encryption for Engineers Fully homomorphic encryption is a fabled technology (at least in the cryptography community) that allows for arbitrary computation over encrypted data. With privacy as a major focus across tech, fully homomorphic encryption (FHE) fits perfectly into this new narrative. FHE is relevant to public distributed ledgers (such as blockchain) and
Blockchain Introducing "Sunscreen" One of our research areas is to create a secure, private, flexible smart contract scheme (“SPF,” hence the name “Sunscreen”). What initially started as a small(er) project to instantiate private smart contracts on Ethereum has become much more ambitious once we realized we cannot achieve our vision for a
