The Cardano Testnet has successfully hard forked!

“We’re happy to report that today at 20:20 UTC the IOG team has successfully hard forked the Cardano Testnet. This is an important next step in the journey towards the Vasil upgrade on mainnet.

We're now inviting SPOs, developers building on Cardano, 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 teams at cardanostiftung & IOG will be working closely with exchanges and DApp/tool developers throughout this process. As soon as we are confident ecosystem partners are comfortable & ready, we'll 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.”
