Identifiers
The DSNP Identifiers form the basis for pseudo-anonymous streams of content. Graph connections are formed through the DSNP User Id.
DSNP User Id
- 64-bit Unsigned Integer
- MUST be serialized as decimal
- MUST be unique per implementation
DSNP Content Hash
- Variable length byte array (fixed length for a given hashing algorithm)
- MUST be a valid multihash encoding of the hash output for the bytes of the content, generated with a Supported Hashing Algorithm
Supported Hashing Algorithms
| Algorithm | Multihash Name | Leading bytes (as varint) | Reference | DSNP Version Added |
|---|---|---|---|---|
| SHA-256 | sha2-256 | 0x1220 | RFC 6234 | 1.2.0 |
| BLAKE2b | blake2b-256 | 0xa0e40220 | RFC 7693 | 1.2.0 |
DSNP Protocol Scheme
- MUST always be the string
dsnp://
DSNP User URI
The DSNP User URI consists of two parts: the scheme and the user id. It is used to identify a user via a URI.
Example
dsnp://1311768467294899700
| part | value |
|---|---|
| Scheme | dsnp:// |
| User Id | 1311768467294899700 |
DSNP Content URI
The DSNP Content URI consists of three parts: the scheme, the user id, and the content hash. It is used to uniquely identify an Announcement from a given user with content.
Any Announcement Types with a fromId and contentHash have a DSNP Content URI.
Example
dsnp://78187493520/0x1234567890abcdef0123456789abcdef0123456789abcdef0123456789abcdef
| part | value |
|---|---|
| Scheme | dsnp:// |
| User Id | 78187493520 |
| Content Hash | 0x1234567890abcdef0123456789abcdef0123456789abcdef0123456789abcdef |
