We have revived the network. The issue we faced was that that all delegates were attempting to produce a block that was invalid. Once we patched a single delegate it allowed the rest of the unpatched delegates to continue as normal.
The problem was that the duplicate transaction check was applying to validation but a duplicate transaction still made it into the produced block.
We will be releasing an official versioned update after some additional review.
I would like to thank everyone who reached out and woke up the dev team at 6AM.
