Decentralized identity ： Completely owned by individuals , An identity that can be controlled autonomously , Its full name is Decentralized IDentity, abbreviation DID.

With the rise of blockchain industry , Based on blockchain Technology DID, It can really avoid personal information being controlled by a third party , Protect your privacy ; At the same time, personal identity is completely controlled and managed by oneself .

Have ENS Names not only make it easier to identify addresses , And with the DNS comparison , It has autonomy without permission .

Even though ENS It is an Ethereum native project , But it integrates bitcoin 、 Data of Wright coin and dog blockchain , Put all this L1 The address is the same as ID Related to . They also have many Web2 Integrate , for example Discord and Twitter.

As new elements are added to the crypto ecosystem , Each element adds the whole DID The total potential strength of the system . Both can increase your more general ENS The value of . our DID It's almost certainly not a simple agreement , But to build an ecological decentralized social network .
