Submit Idle Space Proof

Submits an idle proof to the blockchain, verifying that the miner’s storage node was idle yet responsive during the audit challenge period.

---

Function Definition

pub async fn submit_idle_proof(
    &self,
    idle_prove: BoundedVec<u8>,
) -> Result<(TxHash, SubmitIdleProof), Box<dyn std::error::Error>>

---

Description

This asynchronous call allows a miner to submit their idle proof to the CESS chain. The idle proof confirms that a miner’s node was properly operating during the challenge but had no active service requests at that time.

After submission, the chain updates the miner’s challenge status accordingly:

• The idle_prove field is set to Some().

• If both idle and service proofs are submitted, the value of CountedClear is reset.

• A TEE node is then randomly assigned to verify the submitted proof.

---

Parameters

Name	Type	Description
idle_prove	BoundedVec<u8>	The bounded vector of bytes containing the proof of idleness. It must comply with the maximum proof size limits defined on-chain.

---

Returns

Type	Description
Ok((TxHash, SubmitIdleProof))	Returns a tuple containing the transaction hash and a SubmitIdleProof structure representing the on-chain record of the submitted proof.
Err(Error)	Returned if proof submission fails due to network issues, invalid parameters, or runtime errors during transaction execution.

---

Example

use cess_rust_sdk::{
    chain::audit::transaction::StorageTransaction as AuditTx,
    polkadot::runtime_types::bounded_collections::bounded_vec::BoundedVec,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mnemonic = "bottom drive obey lake curtain smoke basket hold race lonely fit walk//Alice";
    let audit_tx = AuditTx::from_mnemonic(mnemonic);

    // Example idle proof data (replace with actual proof bytes)
    let idle_prove: BoundedVec<u8> = BoundedVec(vec![1, 2, 3, 4, 5]);

    // Submit idle proof
    let (tx_hash, proof_record) = audit_tx.submit_idle_proof(idle_prove).await?;

    println!("Transaction hash: {:?}", tx_hash);
    println!("Idle proof submitted: {:?}", proof_record);

    Ok(())
}

Notes

• Idle proofs must adhere to the on-chain proof size limit enforced by the runtime.

• Submitting an idle proof is mandatory for miners to remain eligible for continued participation in the network’s storage challenge process.

• The proof is verified by a TEE node, ensuring trustless and tamper-proof validation.

• Security Recommendation: Always use a hardware wallet or other secure signing method when submitting transactions to the CESS blockchain. This helps protect your private keys and prevents unauthorized access or malicious signing.
