I wonder someone could give me some advice.
I am planning to work on a Ethereum project with a Solidity smart contract.
The smart contract should contain tokens which can be earned by a person by doing some real life tasks. The tokens can be given away by different parties who validate the tasks i real life.
My question: which erc contract should i use (erc721 for example) to give different parties the possibility to give away their own tokens to people. All tokens from the same party are the same.
Thanks in advance, Arnoud
