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.

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).

Help configuring wagmi
https://github.com/scaffold-eth/scaffold-eth-2 this repo comes with wagmi and hard hat preconfigured you can use it as a sample , but if you are large querying data I would advise you the graph https://thegraph.com/

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.

Is it possible to create subgraphs to query other blockchains that arent supported on the hosted service?
Yes, you can. You'll have to run your own graph-node See: https://github.com/graphprotocol/graph-node

ETH Data pipeline ?
If you only looking to index events of a couple contracts you can use https://thegraph.com to deploy a sub graph for fetching real time data form those contracts

Gitpod x Blockchain
First lets see this repo StoreFront_contracts This project is build with hardhat and also has TheGraph powered indexer in subgraph. The project provides NFT based smart contract like ERC721 build on top of openzeppelin contracts.

How is building in web3 different from building in web2?
Does blockchain tech replace the backend? Absolutely...Not 👀 As I said, web3 is an addition, supplementary and will not replace existing tech. In major blockchain applications, getting data from smart contracts can cost time and sometimes fail if the RPC is unresponsive. You would still want a database and API to query data collected from smart contracts from, say, events. Examples: The Graph, Moralis.

Ask HN: Who is hiring? (November 2022)
OP Labs | Remote-first | Full-time |
Optimism is an Ethereum scaling solution that enables anyone to execute any vision on an open source protocol that will never be captured by private interests. We’re building this technology as a public good, in order to fundamentally change the relationship between companies and their users.
From code to ethos, we are Ethereum-aligned. By operating as a Public Benefit Corporation, we align private incentives with public good and create a positive-sum economic model that provides a sustainable future for the internet.
Today, the most pressing bottleneck to Ethereum and crypto’s growth is its performance and scalability. We are building the most elegant solution to this problem. We do this out in the open because we believe in open source and its ability to accelerate innovation.
To date, we have raised $178M. Both series A and B were led by Andreessen Horowitz and Paradigm.
We are actively hiring for the roles listed here: All open roles are listed here:

Join us in scaling Ethereum and empowering the creators of public goods! :)

Running Perp-maker for Profits and Fun: Part 1
Perp-maker is an open-source market-making template for Perpetual Protocol v2, the most popular dApp on Optimism (a layer-2 scaling solution for Ethereum). Anyone can use or modify the template to facilitate trades on the protocol and earn fees.

Bored Ape Virtual Land Sale Breaks Ethereum, Wastes $180M in Fees
Except that anyone with a minimal involvement with Ethereum already knows that the base layer is not meant to be used on day-to-day operations.
We already learned about the decentralization trillema. The strategy to scale Ethereum through will be through the adoption of "layer-2" systems, where users are expected to be doing their transactions and avoid these costly transactions altogether.
There are roll-ups already dealing with NFT marketplaces [0]. There are roll-ups that can execute any type of ethereum smart contract [1] [2]. There are payment channels that allow completely decentralized and gas-less transfers of ERC-20 tokens [3].

Reasons to invest in $BOBA
Boba is a compute-focused L2. We believe that L2s can play a unique role in augmenting the base compute capabilities of the Ethereum ecosystem. You can learn more about Turing hybrid compute here. Boba is built on the Optimistic Rollup developed by Optimism. Aside from its main focus, augmenting compute, Boba differs from Optimism by:

It's Time for "Pay With BAT" (And a BAT API) to Become a Major Priority
Only if you insist on using the Ethereum blockchain to make simple transfers, which frankly would be quite stupid. It has been more than explained already that Ethereum is scaling through the use of layer-2 systems. You can make transfers on systems like Loopring, zkSync, (soon) Optimism, Arbitrum and Raiden.
