Module ant_protocol 

ANT protocol implementation for the Autonomi network.

This module implements the wire protocol for storing and retrieving data on the Autonomi network.

Data Types

The ANT protocol supports a single data type:

• Chunk: Immutable, content-addressed data (hash == address)

Protocol Overview

The protocol uses postcard serialization for compact, fast encoding. Each data type has its own message types for PUT/GET operations.

Chunk Messages

• ChunkPutRequest / ChunkPutResponse - Store chunks
• ChunkGetRequest / ChunkGetResponse - Retrieve chunks
• ChunkQuoteRequest / ChunkQuoteResponse - Request storage quotes

Payment Flow

1. Client requests a quote via ChunkQuoteRequest
2. Node returns signed PaymentQuote in ChunkQuoteResponse
3. Client pays on Arbitrum via PaymentVault.payForQuotes()
4. Client sends ChunkPutRequest with payment_proof
5. Node verifies payment and stores chunk

Example

use ant_node::ant_protocol::{ChunkMessage, ChunkPutRequest, ChunkGetRequest};

// Create a PUT request
let address = compute_address(&data);
let request = ChunkPutRequest::with_payment(address, data, payment_proof);
let message = ChunkMessage::PutRequest(request);
let bytes = message.encode()?;

// Decode a response
let response = ChunkMessage::decode(&response_bytes)?;
