Scaling Cardano with Hydra

Hydra is an emerging set of tools and protocols being built by IOG based on state channels. It enables for faster transaction speeds, while increasing throughput and minimizing transaction costs. Nebojša Vojvodić, Hydra Product Manager, explains in this presentation how Hydra is something we can use now to scale blockchain for real-world uses.

Hydra will allow Cardano / ADA to grow exponentially!! Can't wait :) One of the most exciting things in the pipeline! Hope 2023 is the year for Hydra :) would be great to market it - hydra is such a great name for the tech as with most components of the Cardano ecosystem!

Thanks for the video. I've been trying to understand hydra heads for a while now. Sounds like Eth layer 2 scaling solutions but native, with the convenience of using ADA for batching the transactions? Will be interesting to see if Cardano defi can really take off next bull run once stablecoins are established and these scaling solutions are being used by dapps.

Hydra is nothing like other L2 solutions. What this video conveniently left out, and what was in all the hydra papers, is that hydra requires trusted parties. All hydra participants must stay online and keep all of their head connections open without interruption. Anytime a user enters or leaves a hydra head, the channel is closed and a new state channel must be created. Most users will not be able to use hydra directly. Trusted parties can use them on the backend, like centralized exchanges or trusted p2p transactions. But because cardano lacks anyway to compute all the head data, heads need their own consensus mechanism or hydra head users could leave the head to cancel unfavorable outcomes before they are finalized. L1 can't do all the computations to litigate that.

Thanks for making this point - it is Very Important!

@@onetwothree4148 and that’s a bad thing then ?

[@elduderino7767]

@@onetwothree4148 this is not accurate, what your are talking about here is the mvp of hydra, not the ongoing development which resolve many of the limitations you mentioned - you are basically suggesting that the mvp (and it's detailed limitations by design) is the solution, no it isn't, it's just the first of many versions, just like cardano was federated to begin with

When?

Now. At the time of typing this the first Hydra head is running on the mainnet. From little things big things grow, it will grow and develop over time. Hail Hydra!
