Planetary-Scale Byzantine Fault Tolerance

Matteo Monti

The scale and pervasiveness of the Internet make it a pillar of planetary communication, industry and economy, as well as a fundamental medium for public discourse and democratic engagement. In stark contrast with the Internet's decentralized infrastructur ...

Online Payments by Merely Broadcasting Messages

Rachid Guerraoui, Daniel Patrick Collins, Jovan Komatovic, Dragos-Adrian Seredinschi, Matej Pavlovic, Matteo Monti, Athanasios Xygkis, Andrei Tonkikh

We address the problem of online payments, where users can transfer funds among themselves. We introduce Astro, a system solving this problem efficiently in a decentralized, deterministic, and completely asynchronous manner. Astro builds on the insight tha ...
