I want to create a database of META tags associated with BTC UTXOs and ETH accounts. Eventually I would like to do the same for all major blockchains and their (multiple in some cases) assets. Ideally I'd want to store all this info on a single distributed database, most likely a new blockchain. I understand that this will be a huge amount of info though but provided the fact that these MEYA tags will be opt-in only this might not be as dramatic as it sounds. What is the most efficient way to go about with this project?
