Why these Tags: an agent read the README and quoted it
- Zero-knowledge proof from the readme:
An implementation of Inner Product Argument Protocol for producing and verifying a compact proof of the inner product of two vectors.
- Cryptography library from the readme:
Blitzar provides an implementation of Multi-Scalar Multiplication (i.e. generalized Pedersen commitments).
An agent gave these Tags from the fixed Tag list in the AwesomeRepos source code. A code check kept each Tag only when its quote is in the text. A wrong Tag? Report an error with the form at the end of this page.

The timeline comes from the creation date and the releases on the Repository Host, the Admission, the Star History, and the Observations. Star milestones show only when the Star History records the day. The list shows up to 5 stable releases from the latest 10 releases recorded. When none of them is stable, one item counts the pre-releases. On the chart of net stars each day, a solid line marks each recorded release.

Health facts
Measured facts in four separate dimensions, each with a date and a source. AwesomeRepos does not add them into one score. AwesomeRepos reads the weekly commits, the changelog, and the community files each week for the 5,000 visible repositories with the most stars and for each rising repository.
