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.

ETH Data pipeline ?
With ethereum datafarm you can parse event logs from contracts without requiring an archive node: https://github.com/Nerolation/ethereum-datafarm
- Quick access to Ethereum data: Ethereum Datafarm uses the Etherscan API to provide easy access to Ethereum Blockchain Event data. May it assist you with research, chart plotting, quantitative analyses, etc.
- Let me open-source this tool for parsing historic event logs into csv format without requiring you to run your own archive node.
- Analyze historical event logs without requiring an archive node. This open-source software provides quick access to on-chain data and can help you with quantitative research, modeling, charting, and more. Have fun!

I created a public dashboard that lets you compare the largest Ethereum-based Stablecoins
Thank you! The underlying data is stored in SQL tables i own. I only have to scrap the latest day and append it to my table. You can do this for free using the Etherscan Api or an Infura node. I built a Python app that can be flexibly configured and that then writes the event data to AWS S3 and BigQuery. Find it here: https://github.com/Nerolation/ethereum-datafarm Best!

I have developed an application to filter the Ethereum blockchain for specific events and save them as a csv file
The ethereum-datafarm was created to allow anyone to scrape contract data and store it in convenient .csv (and .pickle) format. Using Etherscan's public API the tool loops over each block and extracts the relevant event logs.

Building And Deploying A Subgraph (Part 2)
A subgraph according to The Graph (which is a decentralized protocol for indexing and querying blockchain data) is a custom API built on blockchain data. They are queried using the GraphQL query language and are deployed to a Graph Node using the Graph CLI.

Blockchain transactions decoding: making wallet activity understandable
Event is a log entity which EVM smart contracts can emit during transaction execution. Events are very good at signalling that an some action has taken place on-chain. Applications can subscribe and listen to events to trigger some off-chain logic or they can index, transform and store events in some off-chain storage (look at The Graph protocol or Ethereum ETL).

Is Nethereum's GetContractQueryHandler decentralized? If not what's a decentralized alternative for C#?
There are also decentralized network services like The Graph or Pocket Network that provide decentralized access to Ethereum and other blockchain networks. Note that these services primarily provide APIs for querying blockchain data, and may not provide full functionality for sending transactions or executing smart contracts like a full Ethereum node or services like Infura and Alchemy.
