.bit Namespaces

.bit RecordsParsed records are the core of .bit, and the flexibility of records is also the source of .bit's great scalability. A record is a key-value pair, and .bit supports an infinite number of records. As shown above, different applications will read different parse records to do different jobs. Therefore, it is important to manage the namespace of the key of the record. The namespace usage specification is essentially a protocol that can be followed to enable good collaboration between applications.

Namespaces

The key of a record is a hierarchical structure using . separated by a hierarchy, such as address.btc, profile.twitter, custom_key.bitcc_config, etc. Among them, address, profile, and custom_key are called primary namespaces; btc, twitter, and bitcc_config are called secondary namespaces.

.bit has strict constraints on the use of namespaces at the contract level, and currently provides four first-level namespaces.

  • address

    This namespace is generally used to store the user's digital assets receipt address, such as address.btc, address.eth, etc. Also, there is a whitelistopen in new window inside the contract that has built-in mainstream digital assets symbols as legal key.

  • profile

    This namespace is generally used to store users' personal information, such as profile.twitter, profile.facebook, etc. Also, there is a whitelistopen in new window inside the contract with built-in mainstream social network names as legitimate key.

  • dweb

    This namespace is generally used to store decentralized network-related content, such as dweb.ipfs, dweb.resilio, etc. Also, there is a dweb.resilio inside the contract. Also, there is a whitelistopen in new window inside the contract with the mainstream decentralized storage protocol built-in name as a legal key.

  • custom_key

    This namespace is not constrained, and developers can create any name and number of sub-namespaces under this space and define their meaning. For example, custom_key.bitcc_config, custom_key.pgp.master_key, etc.

Note

The .bit contract does not verify the legitimacy of the value of the record, the .bit just provides a convention. For example, a user would normally set the value of address.btc to a BTC address. However, the application should check if this value is really a legitimate BTC address when using this value.

Addition of first-level namespaces

Currently, .bit only provides four level 1 namespaces address, profile, dweb, custom_key, but this is not the final result. The .bit team will gradually add more level 1 namespaces. If you think some namespaces should be added to allow better collaboration between applications. You can report in Github Issuesopen in new window.
