📣 We’re delighted to report that today we have submitted an update proposal to hard fork the Cardano Testnet, and commence the countdown for the #Vasil mainnet upgrade.

With over 75% of testnet blocks being created by the new Vasil node (1.35.0) we now have a good chain density to proceed safely.

Thanks to all the SPOs who continue to support the testnet, and their coordinated effort to ready the network for the Vasil HFC event. Once the changes have taken effect after the start of epoch 215 at 20:20 UTC on 3 July, the Cardano testnet will start to enjoy the new #Vasil enhancements and capabilities that we’ll soon see on mainnet. ❗️NOTE: cost model changes will take effect on 8 July – the epoch after – so kick off your regression testing first. ❗️

The Vasil upgrade – named in honor of long standing community member, the late Vasil St Dabov – brings significant performance and capability upgrades to Cardano.

Vasil improvements include higher throughput through diffusion pipelining to a better developer experience via much improved script performance & efficiency (plus lower costs). It is Cardano’s biggest and best upgrade to date.

It is also the most complex program of work we’ve undertaken. And the whole community is involved. As shared previously, our prime concern is ensuring we manage this upgrade in a way that is safe and secure.

The community has requested a minimum period of 4 weeks to allow SPOs, developers and exchanges the time they need to test and upgrade before hard forking the #Cardano mainnet. Once everyone is comfortable and ready, we can go through the same process to upgrade the mainnet to Vasil.

👉 Join us for #Cardano360 this Thursday, where we’ll introduce more of the IOG team plus some of the community collaborators #BuildingOnCardano and working so hard behind the scenes preparing for the Vasil upgrade. Subscribe for the latest: https://youtube.com/iohkio

Thanks to you all for the continued support. We couldn't do this without you. 🙏🏼
