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.

How do you find underlying addresses or balance/transactions from a Bitcoin xpub, zpub, or ypub address?
pip3 install git+https://github.com/mcdallas/cryptotools.git@master#egg=cryptotools

A from-scratch tour of Bitcoin in Python
I’ve made something similar in order to learn how everything works and made it into a python library. Everything is in pure python with no dependencies, only std lib. I’ve implemented all the crypto stuff, address generation including HD, transaction serialization and even the bitcoin script. https://github.com/mcdallas/cryptotools

Generate ECDSA Public Key from Modulus
The easiest would be to use a crypto library, import the public key as a point directly and check the signature. If you are familiar with python this should be easy enough: https://github.com/tlsfuzzer/python-ecdsa
What are some alternatives?
RsaCtfTool - RSA attack tool (mainly for ctf) - retrieve private key from weak public key and/or uncipher data
MasquerBot - A TelegramBot for true paranoids.
ecdsa-private-key-recovery - A simple library to recover the private key of ECDSA and DSA signatures sharing the same nonce k and therefore having identical signature parameter r
swift-crypto - Open-source implementation of a substantial portion of the API of Apple CryptoKit suitable for use on Linux platforms.
awesome-blockchains - A collection about awesome blockchains - open distributed public databases w/ crypto hashes incl. git ;-). Blockchains are the new tulips :tulip::tulip::tulip:. Distributed is the new centralized.
blockchain_implementation - Simple blockchain implementation using python and flask. It implements basic concepts of blockchain, like proof of work, mining, consensus, generating and validating the signature on transaction etc.
