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.

Ssss: Shamir's Secret Sharing Scheme
A few months ago I built a CLI frontend for Hashicorps shamir secret sharing implementation in Go. You can find it here: https://github.com/dennis-tra/shamir
It combines the two separate commands in the article into one.

Use MPC instead? Sadly there are not enough mature open source projects around: https://github.com/ZenGo-X/multi-party-ecdsa and you can always take a look at https://github.com/rdragos/awesome-mpc
Sadly companies like Unbound were acquired by Coinbase and the OSS codebase is not longer maintained: https://github.com/unboundsecurity/blockchain-crypto-mpc

Answering questions about our new secure crypto app
Ha nice call!
Unfortunately we have not completed a satisfactory security audit. We engaged with one company, but I don't think they were worth their salt. The problem is that the "good" companies are much more expensive, so it's a consideration of the value of the security audit. (If you know of a reputable company that would like to audit for free though...)
The code is not yet open source, but we are primarily expanding on this open-source library. https://github.com/ZenGo-X/multi-party-ecdsa

Potential attack on threshold ECDSA prevented, counter-terrorists win!
As true decentralized security enthusiasts, we quickly got in touch with ZenGo and fixed the discovered security breach in a pull request. It was soon approved and merged into their TSS library. The researcher who found the attack was granted a bug bounty, the biggest in ZenGo’s history.
