It’s the same as with Bitcoin:

- wait a bit to make sure that you can talk to different people on the network and see what each of them see

- check checkpoints on twitter or websites like etherscan (are they seeing the same thing I’m seeing?)

In projects like Mina, since you do not download the history of the chain (there’s a single zero knowledge proof of a few kB that covers the whole history) you must rely on a marker for “chain quality “ to differentiate potential forks.

Note that there was also some research on how to get signal from the transactions you see that you’re on the correct fork (from some ex colleagues working on libra): https://eprint.iacr.org/2019/1440.pdf
