You don’t have to share other information like your name/address, a privacy you can’t enjoy with physical credentials
The best part is the #blockchain like Dock's doesn't store any data. It only stores information that is needed to validate the authenticity of the credential
您不必共享其他信息，如您的姓名/地址，这是一个您无法通过物理凭据享受的隐私
最好的部分是像Dock这样的区块链不存储任何数据。它只存储验证凭据真实性所需的信息
