$DAI address on @optimismPBC is 0xda10009cbd5d07dd0cecc66161fc93d7c9000da1 - how cool is that ? 🤯😅 Watch for this $DAI to get some superpowers soon(tm) 🚀

With the lock-mint bridge you normally expect that the amount of locked tokens in a bridge is greater than amount of tokens minted on a destination chain. That's true for *most* bridges, but not all. Let's have a closer look at @MultichainOrg 👇🧵

Let me show you how to pull data from blockchain using storage diffs and why I think this is a game-changer for many apps. I will use a simple example: fetch @arbitrum whitelist of Validators that can submit fraud proofs 🧵👇

After describing on-chain components of @worldcoin a lot of people asked what is the offchain infra. Given that it is not open-source, I can only rely on the documentation, but assuming that Orb does what it claims to be doing, this is how I see the whole system in one picture

Let's dive a little deeper into what @optimismPBC has actually done - they've announced "compression" that promises to significantly reduce L2 transaction fees for end users. How come ? 🧵👇 /1

Stop saying @0xMantle is using EigenDA or is "powered by EigenDA". EigenDA does not even exist yet on mainnet. So, what is MantleDA and what is its relationship to the future EigenDA ? 👇🧵

Many OpStack chains that used to post data to Ethereum seem to have started posting it elsewhere. Now to fetch full history you have to source data from more than one place. Do you think this trend will reverse with 4844 when posting data will be significantly cheaper ?

Being an Ethereum Rollup is like having the strongest army in the world securing your estate. Becoming Cosmos chain you are are now protected by your token holders. Unless you use "interchain security" (upcoming feature) in which case you pay $ATOM holders for protection.

My first take on @Blast_L2 and the risk of your deposits there. The idea to invest your funds put in a bridge is not new, but Blast takes it to the new level (in terms of TVL, at least) 👇🧵

Posting data to DA layer such as @CelestiaOrg is clearly different from posting data to a computer in your uncle's basement. We should stop with this false dichotomy of onchain/offchain data. What matters are trust assumptions and security guarantees that come with them

TL/DR - If an upgrade has 10 day delay but your forced transaction has 15 day delay you will not be able to exit from a Rollup when malicious upgrade is pushed and your withdrawal transaction is censored (forcing you to use L1 forced tx mechanism). Have a look at some examples:

We should not underestimate value of being able to verify Smart Contracts. @etherscan , even if it is centralised, is an important community public good. We need the same level of transparency for all public zk programs that are verified on Ethereum. Including zkRollups ofc.

3M$ liquidity provided 2.5 years ago to @omgnetworkhq was finally removed yesterday. OMG Network was undoubtedly one of the pioneers of scaling and one of the early implementers of Plasma. I guess now Plasma can be finally put to rest - all attention have moved to Rollups
