Struct ChunkResponse 

pub struct ChunkResponse {
    pub encrypted_chunk: Vec<u8>,
    pub chunk_hash: [u8; 32],
    pub provider_signature: Vec<u8>,
    pub provider_public_key: [u8; 32],
    pub challenge_echo: [u8; 32],
    pub timestamp_ms: i64,
}

Chunk response for bandwidth proof protocol.

Fields

encrypted_chunk: Vec<u8>

Encrypted chunk data.

chunk_hash: [u8; 32]

BLAKE3 hash of the chunk (before encryption).

provider_signature: Vec<u8>

Provider’s Ed25519 signature over (challenge_nonce || chunk_hash).

provider_public_key: [u8; 32]

Provider’s public key for verification.

challenge_echo: [u8; 32]

Echo of the challenge nonce.

timestamp_ms: i64

Response timestamp.

Implementations

impl ChunkResponse

pub fn new( encrypted_chunk: Vec<u8>, chunk_hash: [u8; 32], provider_signature: Vec<u8>, provider_public_key: [u8; 32], challenge_echo: [u8; 32], ) -> Self

Create a new chunk response with current timestamp.

Example

use chie_shared::types::bandwidth::ChunkResponse;

let encrypted_data = vec![1, 2, 3, 4, 5];
let chunk_hash = [7u8; 32];
let signature = vec![9u8; 64];
let provider_pubkey = [10u8; 32];
let challenge_echo = [42u8; 32];

let response = ChunkResponse::new(
    encrypted_data.clone(),
    chunk_hash,
    signature,
    provider_pubkey,
    challenge_echo,
);

assert_eq!(response.chunk_size(), 5);
assert!(response.verify_challenge_echo(&challenge_echo));

pub fn chunk_size(&self) -> usize

Get the size of the encrypted chunk in bytes.

pub fn verify_challenge_echo(&self, expected_nonce: &[u8; 32]) -> bool

Verify that the challenge nonce matches the expected value.
