The Cardano Vasil upgrade successfully launched on mainnet on September 22. Before the upgrade, Cardano-based NFT project Artano released the results of its tests.
Reportedly, when using Plutusv2, script size has been reduced by over 90%, with corresponding cost reductions of over 75%. While lower costs are generally good for attracting new users to the blockchain, concerns now relate to the profitability of SPOs (stake pool operators).
In this regard, Cardano founder Charles Hoskinson responded to the profitability of SPO. Hoskinson said that after the Vasil upgrade, the profitability of SPO is low and transaction fees are greatly reduced. “The side chain solves this problem. SPO will maintain side by side. The chain receives multiple revenue streams and gets paid in these native tokens.
