Cryptography ensures trust and security in blockchain settings and different blockchains use different cryptographic signature methods. Elliptic Curve Digital Signature Algorithm (ECDSA) and Schnorr signatures are two popular signature schemes used in blockchain platforms. Bitcoin and Ethereum, among other cryptographic systems, use ECDSA. Schnorr signatures, originally…

Input Output Global (IOG) has assembled a team of specialist engineers to use the rock-solid foundation of Cardano to build a toolkit for building custom sidechains. Using the toolkit, they have constructed an Ethereum virtual machine (EVM)-compatible sidechain public testnet as a proof of concept. Sidechains make Cardano extensible and more scalable without compromising the…

Mithril is a solution that enables users to obtain the current state of the Cardano blockchain without retrieving its full history. Previous posts discussed how the Mithril protocol works and updated the community on the release of the proof of concept.

At IO ScotFest at Edinburgh, Jean-Philippe Raynaud, technical lead at PaloIT, and Iñigo Querejeta Azurmendi, Cardano lead cryptography engineer at IOG, presented Mithril revealing more…
