We’re happy to announce that today, at Sep 22, 2022 @ 21:44:00 UTC, the IOG team, in collaboration with the Cardano Foundation, successfully hard forked the Cardano mainnet via a HFC event, thus deploying new Vasil features to the chain. While the transition should be smooth (thanks to the hard fork combinator!) you should anticipate a busier than usual network and a longer transition period over the epoch boundary while the network picks up the change.

The Vasil upgrade is the most ambitious program of work we’ve undertaken. Today is a culmination of months of hard work, not just for IOG & Cardano Foundation teams, but for the whole community. Vasil upgrade will bring significant performance & capability enhancements to Cardano, from higher throughput capability via diffusion pipelining to a better developer experience with much improved script performance, efficiency & lower costs.

On September 27, at the start of the new epoch, the new Plutus V2 cost model [delivering lower transaction costs for smart contracts] will be active on the chain, thus opening up full Vasil functionality for the developer community.

With 99% of block producing pools running the new node, SPOs are ready. With exchange liquidity now at c. 90%, most major exchanges are ready, too. If your exchange has not upgraded in time, don’t worry, but you may experience some service interruption until they do. Check status here

Together we traveled the road to Vasil this summer, so a huge thank you to everyone involved for the amazing collaborative effort - this upgrade wouldn’t have been possible without your continued support. Onward!
