Input Output Global’s $4.5m blockchain research hub at Stanford University

Input Output Global, Inc. (IOG) prioritizes a peer-reviewed, academic research-driven process in its quest to develop high-assurance blockchain technologies. The research team has published 130+ research papers across a host of topics, many of which help underpin Cardano’s design principles and IOG’s novel products and services.

This week we are proud to announce our latest…

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…

Layer 1 & Layer 2: all you need to know

When discussing blockchain architecture, the terms 'layer 1' and 'layer 2' are frequently mentioned. These are important concepts that serve two purposes: explain how a blockchain network is built, and provide an easy-to-understand visual representation of what a blockchain network looks like. Let's break these ideas down

Layer 1 & Layer 2: all you need to know

Layer 1: definition

Imagine a wedding cake, with different tiers -layers, if you will-, and the figurine of a couple on top. That beautiful cake rests on a solid stand, the base. For all intents and purposes, that robust and solid cake stand is the first layer (layer 1) that supports the cake infrastructure. You can probably see where this is going. In a blockchain, layer 1 is…
