In mist, all accounts have a colourful pixelated "profile picture" used to identify them. For instance, in this screenshot from the Mist releases page, the Dogecoin Bounty DAO is given a purple profile pic. How are these generated?

    Using github.com/ethereum/blockies But with the same hash of a mist wallet but it generates a different identicon, is there anything to be added to the hash or blockies options for them to be the same?

They use a customized version of the blockies library, namely this one: https://github.com/alexvandesande/blockies.

Our port has a few graphical fixes as well as a significant fix to avoid duplicate icons in the original version caused by a bad random number generator. The upstream author doesn't want to accept the good PR since it breaks existing icons for existing users, so for the foreseeable future, we'll use a fork and not the upstream lib.

  • Are they generated local to each copy of Mist, or would the same contract always have the same icon?

  • They are generated based on the address of an account/contract. It will look the same on all machines (as long as they use the same library/algorithm to generate it). Mar 8, 2016 at 8:57
