When I was flipping through the latest ERC of Ethereum last week, I saw a bunch of http:// (antgroup. com) (Ant Group) email. (Although it says 978, I don't think this number has been assigned yet) This proposal adds enterprise level usage beyond the original wallet address derivation path, and on top of BIP-44, adds company entities and departments: m/44'/60'/entity_id' / department_id' / account_index It is equivalent to using the entity ID of the institution and the department ID of the department for address derivation, and can even be further refined. But I didn't expect this ERC to accommodate six people. Portal: https://(github.com)/ethereum/ERCs/blob/1f5e1584d2499546cf3e911372aba79f3131e7d5/ERCS/erc-978.md
