What’s going on with Cardano’s testnet and Vasil hard fork?

cointelegraph.com:

Cardano founder Charles Hoskinson has continued to refute claims that the Cardano’s testnet is “catastrophically broken,” implying the need to finally move forward with the long-delayed Vasil hard fork.

In a Twitter thread on Sunday, Hoskinson shared his frustration concerning some of the videos claiming Cardano’s testnet has a “catastrophic” issue, which stems from a Friday thread from Cardano ecosystem developer Adam Dean.

The developer claimed that the testnet is “catastrophically broken” due to an undiscovered bug in Cardano’s Node v 1.35.2 that creates incompatible forks — which had managed to slip under the radar of the previous testing.

Following the bug, Cardano released its new client software, Cardano Node v1.35.3, on two separate testnets.

However, Dean noted that because the majority of operators upgraded to v1.35.2 to simulate the Vasil hard fork, v1.35.3 is also “incompatible and incapable of syncing” with the original testnet, and the two testnets are “without a block history.”

Hoskinson has, however, argued that the coding issue found on that node version had been removed in the 1.35.3 update, sharing his frustration that further testing would lead to further delays of the hard fork:

During an Ask-Me-Anything on Friday, Hoskinson also said that there’s been an “unfair narrative” floating around Cardano and its testnet issues, which he called “incredibly corrosive and damaging.”

“You can’t conflate a failed testnet with the mainnet because testnets are constructed and destroyed all the time in this industry. That’s their point. [...] They are in no way, in any way harm Cardano itself.”

On Sunday, Hoskinson noted that “the realities of something this large and complex is that one can be easily trapped by the
