Usage

For users

# mint a nft with id token_id (can be random, must not be already minted)
mint(token_id)

# write a data (my discord id) associated to a token_id of a NFT I own and a type (here the felt 'discord')
set_user_data(token_id, 'discord', 707979046952239197)

For verifiers

# confirm this data is correct for this specific type and token_id (e.g. you got a proof)
set_verifier_data(token_id, 'discord', 707979046952239197)

For external services

# get data written by the nft owner
get_user_data(token_id, 'discord')

# get data written by the specified verifier
get_verifier_data(token_id, 'discord', verifier_addr)

# get data only if both verifier and owner agreed on its value
get_confirmed_data(token_id, 'discord', verifier_addr)
