Safety Under Dynamic Validator Sets

"In proof of stake protocols, however, validators can come and go, and even the absolute size of the validator set can shrink and grow greatly over time. 80% of the validator set at one time may well be smaller than 20% of the validator set at another time, and what in a fixed-set model is clearly equivocation, in a dynamic-set model may not involve any equivocation at all. How do we deal with this?"

STARKs, Part I: Proofs with Polynomials

The explanation of STARKS. “ZK-STARKs resolve one of the primary weaknesses of ZK-SNARKs, its reliance on a ‘trusted setup’. They also come with much simpler cryptographic assumptions, avoiding the need for elliptic curves, pairings and the knowledge-of-exponent assumption and instead relying purely on hashes and information theory; this also means that they are secure even against attackers with quantum computers.”

Town Crier: An Authenticated Data Feed for Smart Contracts

The white-paper. “We present an authenticated data feed system called Town Crier (TC). TC acts as a bridge between smart contracts and existing web sites, which are already commonly trusted for non-blockchain applications. It combines a blockchain front end with a trusted hardware back end to scrape HTTPSenabled websites and serve source-authenticated data to relying smart contracts.”
