On March 25, Cardano launched the scalability protocol Ouroboros Hydra. Its development took 5 years. The protocol allows to achieve a highly scalable blockchain and implement several new features — processing micropayments, insurance contracts and, at the same time, reduce fees.
The protocol is based on the sharding technology called Hydra, which allows to increase the scaling of the second level using the so-called "hydra heads". The technology provides horizontal scalability through improved hardware. According to the developers, this approach is the best compromise between the speed, geographical distribution of participants and their number.
The tests showed that with 1000 “heads” the network can theoretically scale up to a million transactions per second, which significantly exceeds the capabilities of current global payment systems such as VISA.
