Today, let’s take a look at the ‘Four Types of Keys.’
– Locality Key
This is a key of locality, which locally binds different formats of addresses.
– Non-locality Key
This is a key of non-locality, which non-locally binds different formats of addresses.
– Residentially Key
This key actually binds the targeted transaction to the physical object.
– Non-residentially Key
This key only binds the information of the targeted transaction. That is, the physical object is located elsewhere, and this key meticulously records its information.
The concept of locality comes from “quantum”, and residentially from the concept of “file system”. By using these four types of keys, we build the abstraction and ‘decentralization’ of the blockchain bridge. In other words, it’s the base of DAO.
