Struct DagNode 

Source
#[repr(C)]
pub struct DagNode { pub parent_hash: [u8; 32], pub quins_merkle: [u8; 32], pub author_did: u64, pub timestamp: u64, pub message_hash: u32, pub flags: u32, }
Expand description

88-byte Merkle-DAG commit node.

Layout (32+32+8+8+4+4 = 88 bytes, all fields little-endian):

[0..32)   parent_hash     — SHA-256 of parent DagNode bytes; all-zero = genesis
[32..64)  quins_merkle    — SHA-256 of the NQuin slice committed here
[64..72)  author_did      — q_hash of the author's DID string (u64)
[72..80)  timestamp       — ms since Unix epoch (u64)
[80..84)  message_hash    — low 32 bits of q_hash of the commit message
[84..88)  flags           — GENESIS | FORK_DISPUTED | ...

Fields§

§parent_hash: [u8; 32]

SHA-256 of the parent node’s bytes; [0u8; 32] for genesis.

§quins_merkle: [u8; 32]

SHA-256 of the quins slice this commit adds/removes.

§author_did: u64

q_hash of the author’s DID string.

§timestamp: u64

Milliseconds since Unix epoch.

§message_hash: u32

Low 32 bits of q_hash(message) — enough for dedup/indexing.

§flags: u32

Node flags (GENESIS, FORK_DISPUTED, …).
