Khala Mining Guide
Khala Network is Phala’s canary network on Kusama Parachain featuring decentralized mining. We provide an overview to setup the mining environment, followed by a detailed explanation of each step.
We highly recommend workers to first read about Phala’s tokenomics and staking mechanism to understand the calculation of incomings and how the mining proceeds.
Introduction
Workers provide computing power to the Phala Network. Anyone with the appropriate hardware can participate.

This section provides some theory about the mining concepts of Phala and additional background information.

Worker Registration
Registration is required before a worker or gatekeeper can join the network. After that, any parties with secure-enclave-supported devices can serve as workers. To register as a validated worker in the blockchain, Secure Enclave runners need to run pRuntime and let it send a signed attestation report to gatekeepers.
pRuntime requests a Remote Attestation with a hash of the WorkerInfo committed in the attestation report. WorkerInfo includes the public key of IdentityKey and EcdhKey and other data collected from the enclave. By verifying the report, gatekeepers can know the hardware information of workers and ensure that they are running unmodified pRuntime.
Remote Attestation
The attestation report is relayed to the blockchain by register_worker() call. The blockchain has the trusted certificates to validate the attestation report. It validates:
- The signature of the report is correct;
- The embedded hash in the report matches the hash of the submitted
WorkerInfo;
register_worker() is called by workers, and a worker can only be assigned contracts when it has certain amounts of staking PHA tokens. On the blockchain there is a WorkerState map from the worker to the WorkerInfo entry. Gatekeepers will update the WorkerState map after they receive and verify the submitted WorkerInfo.
Offline Worker Detection
The pRuntime of a worker is regularly required to answer the online challenge as a heartbeat event on chain. The blockchain detects the liveness of workers by monitoring the interval of their heartbeat events. A worker is punished with the penalty of his staking tokens if it goes offline during a contract execution.
