Struct ChainedEvent 

pub struct ChainedEvent {
    pub chain_hash: [u8; 32],
    pub event_bytes: Vec<u8>,
    pub prev_hash: [u8; 32],
}

A single event in a tamper-evident hash chain.

Each event records the hash of the previous event (or a sentinel for the first event) so that any tampering with a stored event is detectable by recomputing the chain.

Fields

chain_hash: [u8; 32]

SHA-256 of the preceding event’s hash + this event’s bytes. For the first event in a chain, this is SHA-256(event_bytes).

event_bytes: Vec<u8>

The raw event payload (JSON, binary, etc.) — content is opaque.

prev_hash: [u8; 32]

Hash of the previous event’s chain_hash, or [0u8; 32] for first.
