Submit Service Proof

Submits a service proof for verification on the CESS blockchain. This function is used by storage miners to prove that they have correctly provided storage or data services during a given challenge period.

Function Definition

pub async fn submit_service_proof(
    &self,
    service_prove: BoundedVec<u8>,
) -> Result<(TxHash, SubmitServiceProof), Error>

---

Description

The submit_service_proof function allows miners to submit proof of service data to the CESS chain. When the proof is submitted:

• The service_prove field of the miner’s on-chain state changes to Some().

• The miner’s challenge status is updated and re-evaluated.

• If both idle and service proofs have been successfully submitted, the CountedClear value is reset to 0.

• The blockchain randomly assigns a TEE node responsible for verifying the proof.

This is part of the Audit pallet logic that ensures miners are fulfilling their service responsibilities.

Parameters

Name	Type	Description
service_prove	BoundedVec<u8>	The encoded service proof data, representing the miner’s proof of having served data correctly during a challenge. The vector is size-limited according to network rules.

---

Returns

Type	Description
Ok((TxHash, SubmitServiceProof))	Returns a tuple with the transaction hash and the emitted SubmitServiceProof event upon successful submission.
Err(Error)	Returns an error if the transaction fails (e.g., invalid proof data, signing error, or chain execution failure).

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);

    // Encoded proof of service data
    let service_proof = BoundedVec(vec![1, 2, 3, 4, 5]);

    // Submit service proof transaction
    let result = audit_tx.submit_service_proof(service_proof).await?;

    println!("Transaction hash: {:?}", result.0);
    println!("Event: {:?}", result.1);

    Ok(())
