Mithril proof of concept is now open-source

As Cardano scales, Input Output Global (IOG) engineering teams are working on a range of solutions to boost network performance. Mithril is one such solution, aiming to streamline the speed and efficiency of data synchronization between applications.

During July’s 360 show, Arnaud Bailly – IOG technical architect – shared a Mithril development update.

The importance of Mithril…

Introducing Ofelimos: a proof-of-useful-work consensus protocol

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

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…
