RT: Just read "Soulbound NFT" by @VitalikButerin. I'd repeat that Verifiable Credentials (VC) in W3C DID can solve almost all scenarios in this article in a better way (chain agnostic). And we @ArcBlock_io use VC and DID in our NFT format for fairly long time.

RT：读一下@VitalikButerin的《灵魂绑定NFT》。我要重申，W3C DID中的可验证凭证（VC）可以更好地解决本文中的几乎所有场景（链不可知）。我们@ArcBlock_io使用VC，并在相当长的一段时间内使用NFT格式。
