Learn about how content addressing works and how content identifiers, or CIDs, play a crucial role in IPFS.
CID (Content IDentifier)
Self-describing content-addressed identifiers for distributed systems
CBOR — Concise Binary Object Representation | Specification
CBOR is specified in an Internet Standard RFC. RFCs that serve as Internet Standards are generated by the IETF based on an extensive technical review and quality control process. These are meant to last.

Concise Binary Object Representation (CBOR)
The Concise Binary Object Representation (CBOR) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation. These design goals make it different from earlier binary serializations such as ASN.1 and MessagePack. This document obsoletes RFC 7049, providing editorial improvements, new details, and errata fixes while keeping full compatibility with the interchange format of RFC 7049. It does not create a new version of the format.

DASL: DRISL — Deterministic Representation for Interoperable Structures & Links
DRISL is a serialization format that is deterministic (so that the same data will have the same CID) and that features native support for using CIDs as links. It is based on CBOR, using a narrow profile of CBOR's "Core" featureset called "[[cborc-42]]", specified formally in this IETF document.

Special-Use Domain Names
This document describes what it means to say that a Domain Name (DNS name) is reserved for special use, when reserving such a name is appropriate, and the procedure for doing so. It establishes an IANA registry for such domain names, and seeds it with entries for some of the already established special domain names.
