Did you know that the Ethereum Foundation has a rule that no one can own less than three pets? I actually have to enforce that rule since I'm the Chief Three Pet Officer (C3PO)

Have you ever wondered who supports the client teams? Who payed for the security audits of your favorite client or library used by your favorite defi protocol? Who sponsored the hackathon where the co-founders of your NFT project met? Who provided a stage for your projects...🧵

The chain has been overtaken in difficulty now too, and all affected nodes reorged back to the good chain. No immediate attention required from node operators.

Cool stuff coming up #TestingTheMerge ! Post-merge you will be able to query the finalized block via RPC, giving you the ability to make decisions based on that

PSA: Alright, we'll be probably pushing a TTD override on Ropsten since some miner decided to troll a bit. Issue is that TTD would be hit ~15h from now, while the beaconchain genesis is on monday. Nothing that could happen on mainnet (no one can 2x mainnet hashrate), will update

Withdrawals are working, seeing ~45 ETH being withdrawn per block (16 withdrawals à ~3ETH each) Looks very good to me!

Looking for a good crypto podcast (thats freely downloadable). I've been listening to @BanklessHQ in the gym, but they increased the amount of ads so much that it makes working out pretty hard

I wrote an implementation of ERC-5564 stealth addresses yesterday. It's not production ready yet, but it can be used as a daemon (for listening to stealth announcements) and as a library to integrate stealth addresses in your application Check it out:

@AltoOptimo Nah, the merge will definitely not be delayed by this. It's annoying to go back to the office on a holiday, but it just makes me want push harder to get this merge thing going!

Didn't know that the #Ethereum core dev community was *this* diverse. Over 120 devs from 20+ countries were involved in the merge (the title is not great but the post came out nicely)

I hope this is just a marketing ploy and not how they want to do responsible disclosure. After the last couple of incidents of non-responsible disclosure by companies, I'm getting pretty pissed tbh.

ETH2 validators have a major attack vulnerability that is worse than what is currently known And with the Merge coming closer, this problem should be talked about – but it needs some background: A thread 🧵

I, Marius "destroyer of testnets" van der Wijden did it again. My miner broke the first Kintsugi devnet by creating a sidechain that was followed by some nodes while others followed @parithosh_j 's chain. Post-Mortem coming This should the 4 or 5th testnet that I crashed :P
