Question: how do you find the function hash "b61d27f6" #1
Description
@bokkypoobah this is more a question than an issue
I've noticed this in your https://github.com/bokkypoobah/TheDAOData/blob/master/getTheDAOCreatedTokenEventsWithNonZeroExtraBalance_v3
else if (stack[0].substring(56) == "b61d27f6")
how did you come up with this and what does it mean?
I did some digging, but I didn't come up with much
by looking at this gist it seems to be the hash of the execute function
b61d27f6: execute(address,uint256,bytes)
but I couldn't reproduce the hash from that signature
either using this https://emn178.github.io/online-tools/keccak_256.html
nor did I find it in the link you suggest to retrieve the fuction hashes
https://www.4byte.directory/signatures/?bytes4_signature=0xbaac5300
https://www.4byte.directory/signatures/?bytes4_signature=0xb61d27f6
which doesn't seem to work any more
by tracing the transactions and looking at the CALL functions stacks I've noticed that most (if not probably all) smart contract addresses have that function has as the first paramenter. Why is that?
for instance, here are the 2 CALL functions for transaction '0x694d35e8cacd209636e042e09681491ee82f15424e55db1e23fe7146af2337ad'
