Starknet Africa 🌍 @StarkNetAfrica

It's another Dev Thursday series, and today we’d be helping you understand what Sierra is, and how it works in @CairoLang A thread 🧵👇

Synthetic stress test for my 4844 blob txpool: attach 0-4 blobs to every inbound tx on mainnet and dump it into the blob pool. Result: 10GB worth of pending txs at a churn rate of 150/block = 80ms hit after block processing, negligible RAM usage. CC @jessepollak 😎 #Ethereum

Marco ∎ @Be1garat

@StaniKulechov I would go by elimination, imho what Aave/GHO may want is at least: - not having to bootstrap your security/decentralisation - but inherit them from the best (Ethereum) - have the safest (=> native) bridge to Ethereum This rules out anything that it's not a Rollup

bartek.eth @bkiepuszewski

Big congrats to @0xPolygonLabs (@0xPolygon) for launching Polygon zkEVM. Here are few things that you may assume about zkRollups but you will find here different and should be aware of: 🧵👇

L2s don’t make sense for any chains besides ethereum, who’s value-proposition largely comes from background compatibility, battle-testedness, and slow, careful improvement The best tech from the current temporary era of L2 experimentation will someday be enshrined

Kobi Gurkan | ⬡ @kobigurk

What zkEVM bears forget is that EVM compatibility is not the end goal, it’s the starting point. In a few years time, we’ll all forget about who was the first and even the most optimized. 1/2
