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
Implementing SSS is fun. It’s short and covers using modulo integer arithmetic to compute invertible integer functions. It also overlaps with error correction methods a bit.
I’ve written ones based off Vault’s Go version in both Nim and Elixir:

Ssss: Shamir's Secret Sharing Scheme
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
What are some alternatives?
python-slip39 - Generate Ethereum, Bitcoin, etc. account seed and backup Mnemonics in SLIP-39 format (Trezor & Ledger compatible), with details in printable PDF format. Optionally, also print encrypted JSON and BIP-38 paper wallets.
awesome-mpc - A curated list of multi party computation resources and links.
sss - Library for the Shamir secret sharing scheme
shamir - 🔑 A CLI frontend for Hashicorp Vault's Shamir's Secret Sharing implementation.
keyxn - Pure Nim implementation of Shamir's Secret Sharing (SSS) algorithm
multi-party-ecdsa - Rust implementation of {t,n}-threshold ECDSA (elliptic curve digital signature algorithm).
ehsm - An End-to-End Distributed and Scalable Cloud KMS (Key Management System) built on top of Intel SGX enclave-based HSM (Hardware Security Module), aka eHSM.
