Keccak256 generates 2 hash of the same string

  • I have this struct that represents a piece of information: – – I also have a function that fill these maps: – – As you can se, when I add the new information to the positionToInfo map, I hash the password.
  • I have another function that delete data from this map (positionToInfo).
  • When i check if the data that i want to delete is in the map (thanks the findPosition method) i check if the hashed password (stored in the map) is equal to the hash of the password passed via parameter.
  • Here the code: – – The problem is that the two hashes not match.
  • and then I do: – – the two hash of the same string (password) is not the same.

  • Current mainnet gas limit per block is 8M (7.99), that of Ropsten is 9M (which is actually rather surprising as it was 4.7M two months ago and I did complain about it…).
  • Given the above, what’s the recommended best-practice gas limit for a single transaction?
  • Would 6M be too high and risk not being picked by the miners if I’m aiming for median gas price?
  • After all, is there any statistics on the distribution of the gas used by mainnet transactions?
  • My question is basically trying to gauge the maximum amount of gas safe to use with a reasonable gas price.
