TEA ID

PreviousState Machine ReplicaNextTPM

Last updated 2 years ago

Every TPM ships with a unique asymmetric key, called the Endorsement Key (EK), burned by the manufacturer. We refer to the public portion of this key as EKPub and the associated private key as EKPriv. Some TPM chips also have an EK certificate that is issued by the manufacturer for the EKPub. We refer to this cert as EKCert. The TEA ID is the EKPub of TPM chip inside every TEA mining machine.

This ID cannot be modified or updated once the chip is built. The TEA machine manufacturor can register this TPM ID to our layer-1 blockchain. The registration process requires the TPM manufacturor's EKCert. Anyone can verify any TPM EKPub using such an EKCert.
