- If you are confused how the hacker managed to drain $EMN contract, here’s the exact mechanics of what happened:
- If you are interested in gaining a deeper understanding of the @StarkWareLtd L2 ecosystem, I have prepared a series of threads explaining how can an independent observer by inspecting L1 contracts can be assured of L2 security properties and how STARKs on L1 are actually built 👇
- 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: 🧵👇
- So, it seems like a while ago @arbitrum has updated its Rollup implementation on L1 in a way that, IMO, dramatically increased its decentralisation. Funny, they kind of forgot to inform public about it, let's have a quick look: 👇🧵
- 1/ Surprised to see lot of takes trying to argue superiority of zkRollups over Optimistic Rollups or otherwise. We might end up in a multi-rollup ecosystem where both play slightly different role and will co-exist, here's why: 🧵👇
- Data Availability is by far the most confusing term we ever came up with. Data Publishing + Data Storage are better terms that are more intuitive. DA = Data Publishing, not Data Storage. Here are few facts that you may be unaware of: 🧵👇
- By now you must have heard that Rollups derive their security from Ethereum. Even Rollups that have a centralised Sequencer. So why would you want to decentralise Sequencers ? Surely it adds complexity and can slow down the L2 block production ? 🧵👇
- Ooof, looks like dYdX is no longer comfortable running a centralised order book for reasons easy to guess. So now your funds, instead of being secured by Ethereum will be secured by dYdX token holder majority? (brb, checking who still has 33% of the supply)We’re excited to announce that dYdX V4 will be developed as a standalone Cosmos-based blockchain! 🔗🎉 dydx.exchange/blog/dydx-chain
- 1/ The biggest confusion about Optimistic Rollups on Ethereum is notion of 7-day fraud proof window and the fear that transactions may be "rolled back" during that time. Let's try to explain why this is not the case and look step-by-step at what happens behind the scenes 🧵👇
- Rollups put tx data on L1 chain. This is costly now (note: fees will go down after EIP 4844). Let's see what can go wrong if data is not posted on-chain 🧵
- The @dYdX v3 is frozen. There is no operator. And yet, people are withdrawing funds using L1 - this is what we mean by Stage2 non-custodial systems. What's most amazing is that this is (was ?) one of the first rollups ever launched on Ethereum with tech from @StarkWareLtd
- 16M$ already in Aptos bridge from Ethereum to @Aptos_Network built on top of @LayerZero_Labs. Who cares that half of the contracts are NOT VERIFIED including crucial proof validation lib. Who cares that owner of the Aptos TokenBridge is EOA. Apes will be apes 🦍🤷♂️
