We’re happy to report that today at 20:20 UTC the IOG team successfully hard forked the #Cardano Testnet. This is an important next step in the journey towards the Vasil upgrade on mainnet. We now invite SPOs, developers #BuildingOnCardano and exchanges to commence their final testing and integration processes. Vasil is a complex program of work. Projects will need to check backward compatibility and SPOs will need to make some scripting adjustments. The community has requested a 4 week period following the testnet hard fork to allow for SPOs, developers, and exchanges to test and upgrade before we trigger the hard fork for the #Cardano mainnet. The teams at Cardano Foundation and IOG will be working closely with exchanges and DApp/tool developers throughout this process. As soon as we are confident ecosystem partners are comfortable and ready, we shall submit an update proposal to upgrade the #Cardano mainnet to #Vasil. The Vasil upgrade will bring 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). The Vasil upgrade will also include Cardano cryptographic primitives improvements (enabling greater interoperability options for other blockchains), a tuned Plutus interpreter, and a new cost model, which are all part of Plutus V2 scripts. The Vasil upgrade is the most ambitious program of work we’ve undertaken. And the whole community is involved. Our prime concern is ensuring we manage this upgrade in a way that is safe and secure. Thanks to all the #CardanoCommunity for the continued support. We’ll continue to bring you updates over the next few weeks as things progress.
