Introducing Ofelimos: a proof-of-useful-work consensus protocol
IOG research introduces a new, provably secure, consensus protocol to minimize the energy wastage of proof-of-work blockchains
16 August 2022 11 mins read
The minimization of proof of work's (PoW) energy cost and carbon footprint is one of the most hotly discussed topics in the crypto space. Substituting the PoW primitive in Nakamoto's longest-chain protocol with a proof of useful work (PoUW) has long been theorized as an ideal solution in many respects but, to this day, the concept has lacked a convincingly secure realization.
Today, at the leading international cryptology conference, Crypto, Input Output Global, Inc (IOG) introduces Ofelimos, a novel PoUW-based blockchain protocol whose consensus mechanism simultaneously realizes a decentralized optimization-problem solver. The…
Kachina: privacy-preserving smart contracts
Leveraging ZK Snarks to enable privacy-preserving smart contract functionality without sacrificing decentralization characteristics
5 August 2022 4 mins read
Smart contracts present a standard approach to expressing complex interactions between two or more parties willing to exchange currencies or data in a decentralized way. Smart contracts are effectively automated digital agreements on a blockchain. Written in code, they can track, verify and execute the binding transactions of a contract when predetermined conditions are met. To…
