Idea: Protecting Your Validator from Attacks During Block Proposal to Prevent MEV Theft
Recently, I read a paper on validator deanonymization (linked in the last comment).
TL;DR: An attacker could find the IP address used by your validator. Then, when you're about to propose a block with significant MEV (Miner Extractable Value), the attacker can launch a cheap DoS (Denial of Service) attack on your internet connection. You would miss the opportunity to propose a block. The attacker would then DoS the next validator and repeat this until their validator is selected. This would allow them to propose a block, essentially stealing your winning lottery ticket and grabbing all the MEV.

Do you use disk encryption?
I've released a new version of cryptreboot, a tool for rebooting a Linux system with an encrypted disk that asks for the passphrase to unlock the disk before the reboot, rather than after as in case of normal reboot.
This can be useful when rebooting remote or headless systems, where entering the passphrase typically requires local access. The entire process is handled using an in-memory initramfs patching, ensuring that secrets are handled securely and never touch the disk.
Version 0.3.0 now includes native support for ZFS encryption.
I'm planning to add more features, including passphrase-less reboots, which would be particularly beneficial for desktop users.
If you'd like to try cryptreboot, here's a link. And if you've already tried it, I'd love to hear your feedback!

Cloudflare enabled Encrypted Hello (ECH) for all users (paid Plans need to turn it on explicitly). From now on, all the HTTPS traffic is encrypted, including website address. It makes censorship harder.

If I did not believe in ETH as SOV I would not hold ~90% of my net worth in it.
I just scored - in the Atari Onchain Asteroids game! Can you beat me? www.arcade.fun/?ref=0x4eB9eabD74d2077Cb2016a65a435cfF7508a3795
Fantastic thread covering important Ethereum protocols. Every protocol described in one, short tweet.

From what I understand, one of the things that differentiates solo stakers from professionals is the attestation rate. It is lower in general. This results in lower attestation rewards and may discourage solo staking. How to prevent that from happening?
From my experience, giving a feedback is a valuable gift. But only if the receiving person wants it and is ready to take it. Very good take on honesty.

Wise words!
Today I realized that perfectionism's deadly impact on your life is multiplied by your creativity.
Privacy loves company. Interesting idea.
No cables? No problem. Staking on wifi and UPS battery :)
What DeFi protocols do you recommend for ETH longs/shorts? I know GMX and few others, but what are the best in terms of security, liquidity and fees?
My recent talk on Signed Exchanges - tech nobody knows about, but if applied correctly will make your site super fast for Google-reffered users. The talk is from Ruby conference, but the topic is generic and should be easy to understand for web developers.

Most of the tv series I experience today could serve as examples of how not to communicate with others.
Interesting
Can't wait to see more privacy in Ethereum.

My apartment for rent has just been flooded. Ethereum staking is so much less maintanence!
That's a clever hack!
If this is real, I want it!
I think it may ne useful for people in this channel :)
