Layer 2 scaling solutions are a way to increase the scalability and throughput of blockchain networks like Ethereum, by processing transactions off-chain.

1/ One popular Layer 2 scaling solution is #OptimisticRollup, which allows for multiple transactions to be bundled and processed together off-chain and then only the final result is posted to the main chain.

DA is a main bottleneck of blockchain scaling
off-chain DA & #Celestia's DA layer address this, while (proto-)danksharding aims to scale $ETH DA
but what if I told you danksharding could already be implemented as middleware secured by $ETH validators?!

1/ first of all, let's quickly recap the whole DA (= data availability) issue
you can find an introduction to the DA problem and an overview of the current DA landscape here (which also covers off-chain DA):

0/ Polygon #Avail is a chain-agnostic, modular data availability blockchain built by @0xPolygon. Like @CelestiaOrg, it aims to provide rollups & L1s with a highly scalable DA & consensus layer ✨
A 🧵 on how #Polygon's specialized DA layer works & compares to Celestia (0/34) 👇

@0xPolygon @CelestiaOrg 1/ @0xPolygon has been stealth building Avail since 2020 & has announced the testnet for Q2 2022 in April:
@0xPolygon @CelestiaOrg 2/ Unlike @CelestiaOrg, Polygon #Avail is not built on the #Cosmos SDK and not using Tendermint BFT. However, Avail is also a PoS network, using a nominated Proof of Stake consensus algorithm
0/ Data availability is the primary scaling bottleneck for $ETH-based rollup L2s and a hot topic at the frontier of blockchain scaling. But what is the data availability problem and how is it addressed?
A 🧵 about the DA problem and the current DA landscape (0/XX)
A 🧵 about the DA problem and the current DA landscape (0/XX)
1/ The data availability problem refers to the question how peers in a blockchain network can be sure that all the data of a newly proposed block is available
2/ If part of the data is not available, the block might contain malicious transactions which are being hidden by the block producer
2/12 零知识证明具有三个重要特性。
1. 完备性：只要证明者拥有相应的知识，那么就能通过验证者的验证。
2. 可靠性：如果证明者没有相应的知识，则无法通过验证者的验证。
3. 零知识性：证明者不会泄露任何有效信息。

3/12 #ZK 并不是近几年才提出的新技术，只是由于效率不高和适合的应用场景不多等因素，ZK在很长一段时间内都停留在理论阶段。区块链的兴起为ZK带来新的发展契机。

#Layer2 Scaling is a concept that is used in the #Ethereum communities with some believing it represents $ETH future.
What does this truly imply? 🤌🏼
How does it operate and why do we need it? 🧐
Today we will deep dive into non-custodial solutions ⬇️

1/ Over the past years, #Ethereum popularity has resulted in a massive rise in transactions and, therefore, #network traffic.
With several users competing for faster #transaction processing, a bidding war occurs, resulting in very expensive gas fees for each user.

Once new scaling solutions arise in the #blockchain space, it is always necessary to consider:
- how much they inherit #Layer1 #security and network characteristics
- if they impose stricter user requirements compared to the underlying #Layer1

1/ Yesterday, I highlighted zkSync.
So it only makes sense that I do the same for @StarkWareLtd and their #Ethereum rollup solutions #L222 #StarkEx and #StarkNet

2/ First, again, some high-level Pros and Cons
Pros with using Starkware products
- Increased TPS compared to ORs (~9,000+ TPS on Ropsten testnet)
- Faster withdrawals (no challenge period), enabling better capital efficiency and liquidity
- #Validiums (discussed below)
