Participant Management

Introduction

In the Phi Protocol, we use EthSign to manage artists and verifiers participating in the Cred system. This document explains the participation criteria and management process.

Sign Protocol

Overview of Participation Criteria

The criteria for participating in Cred are primarily determined by the Cred Creator. However, Phi Protocol also maintains a list of trusted participants.

Verifier Participation Criteria

There are two modes of participation for verifiers:

1. PHI_TRUSTED + Custom

   • Verifiers trusted by Phi Protocol (authenticated via EthSign)

   • Verifiers custom-added by the Cred Creator

2. Custom Only

   • Only verifiers specified by the Cred Creator

Artist Participation Criteria

There are three modes of participation for artists:

1. OPEN

   • Anyone can participate

2. PHI_TRUSTED + Custom

   • Artists trusted by Phi Protocol (authenticated via EthSign, with badge)

   • Artists custom-added by the Cred Creator

3. Custom Only

   • Only artists specified by the Cred Creator

Participant Management Process

Custom Allowlist

• Set by the Cred Creator and can be confirmed in the metadata

• Specifies addresses that can participate as verifiers or artists

• Can be updated by the Cred Creator at any time

Trusted Participants

• Trusted status conferred by "Sign by Phi"

• Managed in a blockchain-verifiable form using EthSign

Role of EthSign

EthSign is used particularly for managing the "PHI_TRUSTED" status:

1. Enhanced Security: Utilizes blockchain technology to ensure tamper-resistance and integrity

2. Transparency and Auditability: Stores trusted status in a publicly verifiable form

3. Reliability: Includes a third-party verification process, enhancing trustworthiness

4. Automation and Efficiency: Automates the authentication process, minimizing the risk of errors

Conclusion

Phi Protocol achieves a flexible and secure participant management system by combining EthSign with its own custom lists. This approach ensures the overall reliability and transparency of the system while maintaining the freedom of Cred Creators.
