The 2.5 version of succinct has opened up, and nodes can now be run, but the configuration requirements are relatively high; at least a 3090 card is needed to run it. This is manageable, and you can rent a server.
The more troublesome part now is that it requires staking 1000 prove test coins to run the node... Only users who participated in the first and second phases of testing have test coins.
It is said that you can leave your address in the crashout comment section to receive some; I have already left several accounts, you can give it a try.
However, there are already more than four thousand comments... Don't get your hopes up too high.
Additionally, I heard that in some time, there will be ways to transfer and obtain prove test coins. If you can't get them now, you can wait and see later.
If it really doesn't allow playing, then go all out to mine boundless, no matter what, I don't believe it dares to shut out potential node operators with hunger marketing 😂
