@superboyiii could you test the gas cost?

Hey shargon, thank you for opening this pr, solution better than mine

As @roman-khimov said:

there is MemorySearch there. SUBSTR opcode is available as well.

Maybe we should remove IndexOf

name kinda confusing, but you and @roman-khimov are right.

Now I think that everything can be done with MemorySearch, these methods would only be synonyms of MemorySearch

Yes, a bit confusing.

I also see that now. @roman-khimov Roman is obviously right.

@Liaojinghui It should be done in neo-devpack-dotnet, using MemorySearch

Totally agree. And it will be only related to C#.

It can be synonyms of MemorySearch, maybe it is better.

How about the possible attacks in case of future resync, what is the idea? Mark all with hard fork?

@vncoelho This one will be replaced, new implementation will be in the devpack, and no fork will happen

Sure, just take care because of the other PR involving kecak

Closed because neo-project/neo-devpack-dotnet#796
