NNS and Frostfsid
You can register a TLD domain without a committee signature using Frostfsid. To do this, create a new wallet
neo-go wallet init -w newwallet/wallet.json
Get wallet address:
neo-go wallet dump-keys -w newwallet/wallet.json
[subject-address]
[subject-key]
Create a subject in FrostfsID:
frostfs-adm morph frostfsid create-subject --subject-key="[subject-key]"
Grant permissions to the wallet:
frostfs-adm morph nns give-privilege --subject-address="[subject-address]"
Register domain:
neo-go contract invokefunction [NNS-hash] register "subdomain.domain" hash160:[subject-address] "email@frostfs.info" 10000 1000 1000 1000 -- [subject-address]:Global
