During the recent Cardano 360 event, delivery lead Dimitris Poulopoulos described the testnet as “a dress rehearsal.” The team of developers will be closely monitoring all issues that have to be resolved before the mainnet deployment.
Charles Hoskinson, the creator of Cardano and IOG CEO confirmed that after reviewing the infrastructure, and the state of the testnet, the team decided to greenlight the final test stage.
He further explained that, unlike previous occasions, Alonzo has entered the “primary testnet used for exchanges and all the other people”. Once the HFC infrastructure “rolls over”, it will stay on the testnet until the “update proposals are done” on September 9th, before its launch on the 12th.
