Audit	Open to audit and up-to-date third-party audit	Not open to audit(0), open to audit without up-to-date third-party audit (1), up-to-date third-party audit (2)	25%
Anonymity	Registration and connection does not depend on user's real identity	Real identity required (0), linkable identity required (1), full anonymous (2)	25%
Decentralization	Decentralized storage and administration	Not fully decentralized (0), fully decentralized (1)	Δ%

- Check the reference of code file names with the focusing points
For beginner techies:

- Check the existence of code files in the git repository and view the code
- List the privacy-preserving measures in the doc and seek the reference in the source code

Audit

For non-techies and beginner techies

- Check the audit history of the project

Anonymity

For non-techies:

- List the information required for the account
For beginner techies:
