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.

AMA with the team behind Base, the new L2 incubated by Coinbase – March 21 at 12 pm ET / 4 pm UTC!
open source. we’re building base on the OP Stack — which means that if you want to contribute, you can! you can review the code and start contributing here. we’ll be open sourcing as much as possible, so more people can get involved.

Ask HN: Who is hiring? (November 2022)
OP Labs | Remote-first | Full-time |
https://optimism.io
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:
- Web3: A VC-funded gig economy of securities fraud

***Potential*** Airdrop to Users and Co-Founders - Across Protocol
The Across bridge is the fastest, cheapest, and most secure bridge between L1 and L2 (and soon between L2 and L2 hopefully). Across has integrated with the canonical bridges of Boba.network, Optimism.io, and Arbitrum.io, with more to come. Go take it for a spin and save yourself some ETH here: https://across.to/

I’m sorry how is this a thing? Please can someone explain this to me? Thanks

It's official - I have just declared ETH an official currency and legal tender.

Corporate needs you to find the difference.
The information arbitrage is pretty remarkable because they get a bunch of money for printing air tokens out of thin air and selling a portion of it. They then use the money mainly to control narratives. How many people even know that literally all eth traffic runs through central infura servers? Why? Because it doesn't scale without central servers. It also doesn't scale on-chain which is what they promised 7 years ago when they asked you to give them bitcoin to create a turing complete blockchain. They tried a lot of other stuff before roll-ups with centralized sequencers with trusted multisigs. They even tried to copy Lightning and funded Raiden network.

What Are Layer-2 Scaling Solutions? The scalability trilemma remains one of the biggest issues of the blockchain. Here’s how Layer-2 scaling solutions can help.
Examples: Bitcoin’s Lightning Network, Ethereum’s Raiden Network
-
Has anything fundamentally changed with crypto currencies, blockchain technology or the idea of decentralization in the past few months?
Think of the blockchain as being the settlement layer between banks, and each roll-up or payment channel as its own bank.

State Channels Still Beat All Other Layer-2 Scalability Solutions
Raiden Network - an instant payment solution with low fees compatible with all ERC-20 tokens.

My small business now accepts Ethereum & other forms of crypto! 🥳
Just an FYI: with Hub20 you can accept payments with any Ethereum-compatible blockchain and any scaling solution that uses the RPC interface (e.g, Polygon, Arbitrum, Optimism, Gnosis Chain). It also works with Raiden, which is akin to BTCs lightning network.

Daily General Discussion - March 17, 2022
Raiden Network, ethereum's equivalent of lightning network, has been live on mainnet since 2020. It has little to no traction/usage as rollups are a much better scaling solution than state channels.

Crypto Payment Gateway in Web Development
For those that are technical, the main selling point is its integration with layer-2 systems and support for multiple chains. It doesn't matter if you want to accept payment with Raiden or Arbitrum/Optimism, or xDAI/Polygon or BSC, your frontend does not change at all.

People Don't Want to Run Their Own Bank
The point you are so reluctantly refusing to see is that it is about options and the long tail. Yeah, the majority of business and people are fine with the status quo. It doesn't mean that the rest should just conform.
> Other than that, unless you use Nano, every crypto transaction comes with a fee (...) slower than normal transactions

I don’t understand Ethereum L2 solutions like Loopring, but I have a good understanding of BTC’s Lightning Network. Does Loopring function similar to Lightning?
Raiden network is probably the closest equivalent of lightning network, but there are a couple of other projects using similar technology on Ethereum.
What are some alternatives?
zksync - zkSync: trustless scaling and privacy engine for Ethereum
webui - Raiden's Web User Interface
polygon-edge - A Framework for Building Ethereum-compatible Blockchain Networks
BTCPay Server - Accept Bitcoin payments. Free, open-source & self-hosted, Bitcoin payment processor.
eth-gasnow-extention - GasNow extension for browser
ethereum-org-website - Ethereum.org is a primary online resource for the Ethereum community.
protocols - A zkRollup DEX & Payment Protocol
graph-node - Graph Node indexes data from blockchains such as Ethereum and serves it over GraphQL
kasisto - A Monero Point of Sale payment system
lido-dao - Lido DAO smart contracts
