After two delays, the Cardano blockchain has finally deployed its Vasil upgrade and hard fork, significantly improving the performance and capability of the network, blockchain firm Input Output Hong Kong (IOHK) said via Twitter on 23 September.
According to the announcement, the Vasil upgrade was triggered on Thursday at 9:44 pm UTC and successfully hard forked the Cardano mainnet, which now has better programmability and throughput potential. The upgrade us part of the Basho era, one of the key development phases of Cardano that focuses on optimization, scalability, and interoperability.
One of the significant improvements Vasil has made to the network is using block transmission without full validation to allow for faster block creation. The upgrade also made changes to Cardano’s Plutus smart contract language, making it more efficient, which will allow decentralized finance (DeFi) project to create more powerful and cost-effective applications. The full capabilities of Plutus v2, however, will be made available for developers on 27 September.
The upgrade was activated after several months of delays, which were caused by bugs found on its testnet. Originally scheduled for June, Vasil’s launch was delayed by one month due to seven technical bugs that still had to be fixed. In July, IOHK once again postponed the launch to ensure that all involved parties — including exchanges and API developers — were ready for the transition.
Caradno’s upgrade and hard fork was named “Vasil” in honor of the Bulgarian mathematician and Cardano ambassador Vasil St. Dabov, who passed away late last year.
