App developers, betting pool operators (SPOs), exchanges and other ecosystem participants have four weeks to “finally test and integrate” the update before launching it on the mainnet.

“Vasil is a comprehensive study program. Projects will need to check for backward compatibility and DPTs will need to make some changes to script execution,” IOG said.

The update also includes:

• improvements to Cardano’s cryptographic foundations to extend interoperability to other blockchains;
• configured Plutus smart contract interpreter;
• A new cost model that is part of the Plutus V2 scripts.

“The Vasil update is the most ambitious work program we have undertaken. And the whole community participates. Our main task is to ensure that the upgrade is managed safely and reliably”, stressed the IOG developers.

Recall that in June, the company’s specialists had to postpone the activation of Vasil due to unresolved technical problems.
