Hydra: Next Generation State Channels - Arnaud Bailly & Sebastian Nagel

Accommodating a growing number of participants and transactions is a problem in any distributed consensus system, and blockchains make no exception, especially as they are gaining attention from a wider audience. Hydra Head Protocol is a Layer 2 solution for (e)UTxO based distributed ledgers that is part of Cardano's strategy to accommodate this growth, allowing the creation of Isomorphic Multi-party State Channels between a limited set of participants.
This talk reflects on our experience taking Hydra Head from a research paper to a production-ready system, over the past year and half.
