IOHK reveals layer-2 scaling solution for the Cardano blockchain

IOHK, the engineering company co-founded by Charles Hoskinson and Jeremy Wood, this day has unveiled Ouroboros Hydra (Hydra), an off-chain protocol, which permits vastly elevated scalability for the Cardano blockchain, even as serene offering low latency and minimal storage per node.

The Hydra solution permits a differ of beforehand unfeasible on a usual basis applications, including micropayments, voting, insurance contracts, and any app that requires low costs or instantaneous confirmation.

Hydra is the consequence of a 5-year EU-funded collaborative analysis mission, led by IOHK researchers and diverse companions from the corporate’s blockchain analysis lab at Edinburgh College.


The analysis was funded by the EU’s ‘Privilege Mission’ as a part of its mission to unite European researchers in pursuit of recent cryptographic protocols for blockchain and dispensed ledger technologies. These technologies will be high-quality of supporting the whole lot from online voting to insurance contracts.

Layer-2 Resolution

Hydra is an a must-like a part of IOHK’s map to build a highly scalable proof-of-stake protocol for Cardano – IOHK’s decentralized public blockchain and cryptocurrency mission. It’s labeled as a layer two blockchain scaling solution, which is in a position to take a seat on high of the Cardano Protocol and magnify its working lag.

The radical leap forward sees every one connecting to the community producing 10 extra ‘heads’, every offering an extra ‘lane’ of throughput for recordsdata and transactions. Due to this fact no longer like ragged programs, the machine for sure turns into faster, with much less latency because it scales.

College of Edinburgh simulations affirm that every Hydra head can currently take care of round 1000 transactions per second, but, it’s additionally probably to extra optimize the formulation. As more heads are added to the protocol, more scaling is attained – so with 1000 heads, the community may perhaps perhaps theoretically scale to 1,000,000 transactions per second – conveniently in design over most up-to-date world fee programs similar to VISA.

Professor Aggelos Kiayias, Director of Edinburgh College’s Blockchain Laboratory mentioned:

“Solving the scalability demand is the holy grail for the overall blockchain space. The time has advance to follow a principled, evidence-basically based entirely mostly advance in designing and engineering blockchain scalability solutions and this analysis is a decisive step on this direction.”

The white paper reveals that Hydra achieves end to the theoretical maximum amount of transactions probably within the barriers of community lag, geographical distance, and the preference of participants. Genuinely, the bottleneck turns into the community connection between the participants, no longer the protocol.

Crucially, Hydra demonstrates enough transaction speeds to facilitate ‘micropayments’ – fuelling the replacement of, shall we embrace, subscriber-basically based entirely mostly online selling with a brand recent machine enabled by scaling, achievable best by Cardano’s Hydra functionality. This would allow online newspaper readers to pay per article reasonably than per month, or avid gamers to arrangement end virtual gadgets within video games for fractions of a penny.

Charles Hoskinson, CEO of IOHK mentioned:

“Our Ouroboros Hydra solution is the consequence of a huge world analysis effort, spanning 5 years, that aimed to resolve the safety and scalability problems affecting blockchain. As soon as utilized, it may perhaps perhaps allow the Cardano blockchain platform to scale to direction of more transactions than any assorted blockchain or old college fee machine. IOHK’s Ouroboros whitepaper is a capstone of our crew’s analysis and has been cited greater than 1000 times. It forms an a must-like a part of Cardano’s closing map of increasing a blockchain-basically based entirely mostly world financial and social working machine.”
