Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

NPM Provenance Public Beta
untrue.
The Root CA is generated by the sigstore community (five folks, two from academia) this is what is used for the trust root for the signing. Right now github exchanges a OIDC token for a sigstore root chained cert.
GitLab are currently adding themselves, to have the same capability.

Implementing code signing and verification
They also say thay they integrate with Fulcio which seems to be a self-managing CA. Never tried it, though.

Freezing Requirements with Pip-Tools
https://docs.sigstore.dev/ :
> sigstore empowers software developers to securely sign software artifacts such as release files, container images, binaries, bill of material manifests and more. Signing materials are then stored in a tamper-resistant public log.
> It’s free to use for all developers and software providers, with sigstore’s code and operational tooling being 100% open source, and everything maintained and developed by the sigstore community.
> How sigstore works: Using Fulcio, sigstore requests a certificate from our root Certificate Authority (CA). This checks you are who you say you are using OpenID Connect, which looks at your email address to prove you’re the author. Fulcio grants a time-stamped certificate, a way to say you’re signed in and that it’s you.
https://github.com/sigstore/fulcio
> You don’t have to do anything with keys yourself, and sigstore never obtains your private key. The public key that Cosign creates gets bound to your certificate, and the signing details get stored in sigstore’s trust root, the deeper layer of keys and trustees and what we use to check authenticity.
https://github.com/sigstore/cosign
> our certificate then comes back to sigstore, where sigstore exchanges keys, asserts your identity and signs everything off. The signature contains the hash itself, public key, signature content and the time stamp. This all gets uploaded to a Rekor transparency log, so anyone can check that what you’ve put out there went through all the checks needed to be authentic.

Sigstore: A Solution to Software Supply Chain Security
fulcio is a root CA for code signing certs. Its job is to issue code-signing certificates and to embed OIDC identity into code-signing certificate. From this description we can see that it performs these tasks in steps 2, 3, 4 and 8.

Sigstore – A new standard for signing, verifying and protecting software
Did you follow the link to the project list on Github? The actual tool for doing the signing, cosign, is just a binary you can install on your device and generate signatures and keys yourself. The "service" part of it seems to just be having your public certificate vouched for by a trusted code signing CA. I don't see anything in the tooling that requires your users to only trust that CA. If you want to sign your cert with your own CA and tell your users to trust that instead, they seemingly can do that, just as you can do that today in browsers. That you can't do it with Firefox extensions and mobile app stores is a limitation intentionally built into the distribution channel. It's not a limitation of PKI itself. iOS, Android, and Mozilla could have chosen to let users install arbitrary trusted CAs. You shouldn't dismiss all PKI based on the fact that a few vendors have chosen to implement it in a crappy way to make walled gardens.
It doesn't say this on the announcement, but looking at the actual PKI service (https://github.com/sigstore/fulcio), it seems to be entirely possible to self-host the service and roll your own CA.

Don't Panic: A Playbook for Handling Account Compromise with Sigstore
> We’ve adopted a security disclosures and response policy to make sure we can responsibly handle critical issues. We have an initial Security Response Committee, who for each vulnerability reported will coordinate to create the fix and release, and keep the committee looped in. The policy in full is here: https://github.com/sigstore/community/blob/main/SECURITY.md
