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.

Ask HN: Who is hiring? (December 2023)
I am a developer there, hit me up if you are interested || have any questions
I highly recommend to visit our site and click around: https://l2beat.com
Repo for more technological context: https://github.com/l2beat/l2beat
We are running & maintaining the site (https://l2beat.com). Our work is to look on the current Layer 2 deployments on Ethereum & show risks and statistics to the end user. Very interesting thing is that we are a public goods company trying to stay as objective as possible in the industry full of subjectivity. What I mostly like in this job is that I am a part of the project shaping how it looks, not only mindlessly taking someones orders.

Should Ethereum be okay with enshrining more things in the protocol?
Ecosystem fragmentation is not necessarily a bad thing. It leads to rapid development through competition. Different L2s are competing against each other to provide the best service and that has lead to a cambrian explosion of solutions. It's also a very effective way to explore the solution space, I'm sure many will disappear, others will get eaten, and at some point there will be consolidation. But all this seems like a good approach early on when tackling complex problems for which the ideal trade-offs are not entirely obvious. Explore as much of the solution space as possible and trim later on.
A perhaps more pernicious problem is liquidity fragmentation. Moving assets between L2s is a tedious friction that leads to fragmentation of liquidity. In that respect, zero-knowledge rollups present a big advantage as you can share liquidity between them as long as they share some zk-circuits that allow to prove statements to both chains. All this is being very actively worked on. And the technology behind it is short of fascinating. The typical HN audience would have a huge hard-on for it, if they didn't have such a strong preconception against crypto-anything.
If anyone is curious to learn more about L2s a good starting point is here: https://l2beat.com/
And if you want to see Ethereum scaling progress you can check it here: https://l2beat.com/scaling/activity
The next major upgrade to the protocol, slated for late this year or early 2024 (date is not finalized yet), will focus on scalability by making L2 activity veeery cheap.

Ethereum L2 Optimism Sees 500% Growth in Active Users Since July
Polygon is crushing it in their own right. The best business development skills in the game. They have a multitude of ZK solutions on the way with only Polygon Edge being live right now. Definitely a big player, more so when their ZK solutions are on the mainnet.

What is the best way to learn ethereum?
read Mastering Ethereum. If you are looking to make your own sidechain, I'd also look at Polygon Edge. It's much easier to understand what is happening under the hood there.

Bridging in Crypto: from Surge to Lifestyle
If you bridge BNB — Binance Smart Chain’s native BEP-20 token — to Polygon, a wrapped BNB-equivalent, ERC-20 token will be deposited to your wallet, connected to Polygon. This allows you to take advantage of potentially higher yields on farms and tap on liquidity that would otherwise not be available on the Binance Chain, for example.

Layer 1 vs. Layer 2
Similar to how Layer 1 networks have different approaches to consensus, each layer 2 network will implement a scaling solution, or means to map transactions back to its layer 1. For instance, a commonly discussed layer 2 scaling solution is the implementation of zero-knowledge rollups. The idea is that a side-chain performs transaction ordering and processing and submits mathematical proof that they have processed the transactions fairly. Some examples of layer two scaling solutions are the Lightning Network, Polygon, and Starknet. The majority of scaling layer two solutions depend on cryptographic systems. For resources on the cryptography behind zero knowledge proofs I recommend this resource. The watered down version of what is happening, is that a mathematical proof is created by a verifier that some knowledge is correct.

Too expensive to use. (Dont get mad)
As for which L2s to use, the two most commonly used ones right now are Polygon and Arbitrum, but there are others (18 right now, 19 if you include Polygon). L2Beat is a good site to use to look at the different L2s available and compare them, and L2Fees is good to use to compare fees between different L2s and the L1 chain.
There's generally three different types of L2s in use right now: - Side chains, which are technically not L2s, but most people consider them to be L2s. The main one is Polygon, but there are others. These are entirely new blockchains with their own consensus and security, that support the EVM (the engine at the heart of Ethereum) and many of the same dapps that are on Ethereum, that are connected to Ethereum (or even other chains) via a bridge. - Optimistic rollups, which are true L2s. The two main ones right now are Arbitrum and Optimism. These are harder to explain, but are basically special contracts on the Ethereum L1 that take a bunch of transactions (both from the Ethereum L1 and from within the rollup itself), will execute them off the L1 chain (allowing them to be executed much, much faster), and will then post transaction data onto the L1 chain, where transactions are secured by the L1 chain. These support the EVM, and are somewhat comparable to side chains in how much they reduce fees, but are much more secure than side chains, since rollups in general piggyback off the L1 chain for their transaction security and decentralisation. - ZK rollups. There's a few, the main ones right now being Loopring and dYdX, with StarkNet being a promising one that I'll talk about at the end. Like optimistic rollups, ZK rollups are the same special contracts that execute transactions off chain and post data on chain, but ZK rollups are more secure and faster/cheaper than optimistic rollups, with one major downfall: the (current) lack of EVM compatibility. ZK rollups at the moment do not support the EVM, and so cannot support any dapps whatsoever, with dapp-esque features having to be built directly into the rollup (Loopring is a decentralised exchange in rollup form, as is dYdX, for example). It's best to think of these as single applications, but work is being done to make an EVM-compatible ZK rollup, in the form of StarkNet. If StarkNet is successful, we should see dapp ecosystems flourish in ZK rollups, like they have in side chains and optimistic rollups.
