What is the difference between this and the Accepted property?

This IsSuccess property can be removed as it was an additional property added for testing purposes. It was redundant with the existing Accepted property which already provides the same functionality. The IsSuccess property has now been removed to simplify the codebase and avoid duplication.

I thing PoW is enough the whole namespace is nostr anyway

I noticed you use the "nonce" everywhere, can you add it to the const strings on the tag instead? or a local const...

This is wrong, The id of a different event can't fit a new event
| Kind = miningEvent.Kind, | ||
| Tags = miningEvent.Tags, | ||
| Content = miningEvent.Content, | ||
| Sig = miningEvent.Sig |

The sig can't fit an event with changed parameters

The sig you are setting here is not valid, better to sign it again

I guess we don't need this

You also need to check that the difficulty is greater than or equal to the target difficulty

Why use int if we only look at the char value?

I'm not really sure, but why do we have a second implementation of the PoW instead of calling the implementation on the NostrEvent?
