The IOG & @CardanoStiftung teams – plus the whole dev and SPO community – continue to work hard preparing for the #Vasil upgrade, bringing multiple enhancements to #Cardano.

Here’s a quick recap of where we’re at and what you can expect…👇

Thread🧵
1/9

A new node version - 1.35.3 - has been released for use on the Vasil dev net and the new pre-production environment. As long as we do not encounter any significant new issues, this will be the version with which we’ll trigger the #Vasil upgrade on mainnet.
🧵2/9

This new pre-production environment has been set up to provide a ‘clean’ and more agile environment to test against 1.35.3 for exchanges and SPOs. We invite SPOs, developers #BuildingOnCardano, and exchanges to commence their final testing and integration processes.
🧵3/9

If you would like to continue testing on the Cardano testnet, please keep in mind that node version 1.35.2 will be the only version that works. Additionally, any SPOs running 1.35.0, 1,35.1, or 1.35.2 on the #Cardano mainnet should immediately upgrade to 1.35.3.
🧵4/9

The #Vasil upgrade is the most ambitious program of work we’ve undertaken. None of this would have been possible without the community’s support - it’s been a real team effort.🙏 Our prime concern is ensuring we manage this upgrade in a way that is safe and secure.🛡️
🧵5/9

Three critical mass indicators will determine when we trigger the mainnet update:

1⃣ 75% of mainnet blocks being created by the final #Vasil node candidate
2⃣roughly 25 exchanges upgraded representing c. 80% of liquidity
🧵6/9

3⃣key mainnet #DApps (inc. top ten by TVL) confirming they have upgraded to 1.35.3 on PreProduction and on Mainnet
🧵7/9

Thanks to all the #CardanoCommunity for the continued support. 🫶

We’ll continue to bring you updates over the next few weeks as things progress.
