Just claimed my $BONSAI for playing the @lens/cryptothegame
🌸Pink🌸 is nice, isn't it?
Any way to claim Bonsai after I couldn't click on it? I saw the claim screen and couldn't click on it because the app needed an update. After the update, the claim screen never showed up and I don't see any option or link to claim. From what I saw, I'm not the only one with this problem.
Minted GHO. Ready for LFGHO!

I need YouTube gear advice: For video, probably Sony a6600? But which lens goes best with that? For mic, I pretty much settled on Shure SM7B + Rodecaster Pro. Any suggestions,tips? Especially regarding lens.

I just contributed to the 🕯️ KZG Ceremony 🕯️ to help scale Ethereum After months of trying, it finally went through. There's 0 waiting in the lobby now, go ahead and do it, if you wanted to but couldn't do it in the past. ↓ Add your own randomness ↓ ceremony.ethereum.org
I'm not hacking this time but I'm supporting hackers! I'm offering $5k bounties up for grabs at #ETHTokyo Just use QuickAlerts (blockchain notifications) or QuickNode's NFT API or Token API and you can go home happier, smarter, and richer :) Find me at QuickNode table if you have any questions (the table is right across the @lensprotocol.lens / @aaveaave.lens booth, as you can see in the photo).
What is zero-knowledge proof? If Bufficorn could finally get his head around the concept, you will, too. https://lenstube.xyz/watch/0x2f3b-0x0b
What is Zero Knowledge Proof - Explain Like I'm Five A simple and straightforward explanation of what zero-knowledge proof is, what it means to be zero-knowledge, and an example to visualize and help understand the concept, real-life use cases, and challenges facing ZKP technology.

What is zero-knowledge proof? I saw so many explanations and examples that were too complicated, too convoluted, or just unintuitive. So I created the "Explain Like I'm 5" version of zero-knowledge proof. I hope this will be clear (and entertaining) enough. So what is zero-knowledge proof? It's a mathematical technique where you can prove you're right without even telling what you're right about. It will be easier to explain with a clear example. A bad wizard kidnapped our friend Cypher McBlockchain and cloned him. Now there are 2 Cyphies, but only one is real. To you, they are identical, but I know how to tell which one is real. And I will prove that I know how to distinguish them, but not which is which. Let's take our Cyphies. Now show one of them to me and hide him. Then, after hiding the first one, show one of them to me, randomly. If you show me a different one, I will tell you that you have switched them. If you don't switch, I'll say that you're showing me the same one. This will show you that I know how to tell the difference between the two. But... wouldn't it be just pure luck? No, because we will continue this way as many times as you want. Every time I will tell you if you're showing me the same Cyphie or if you have switched them. If we continue doing this many times and every time I am right, at some point, you will be convinced that I do know the difference and can distinguish the real and fake Mr. McBlockchain. And this is how zero-knowledge proof works. ZKP is not a strict mathematical proof though (the one using axioms and logic). It's proof based on probability. The result is proved from a statistical point of view. Here's a full video with much more info about ZKP: use cases, requirements, challenges, etc. https://youtu.be/t58q7uPDfvY
As mentioned on Twitter earlier today, I hope community effort in hiding / muting / cleaning up clearly spam accounts is going to be effective for the platform as a whole. Potential airdrop resulted in 100+ fake/spam followers for me in less than a week. I'm rooting for effective self-governance. cc @stani.lens
Solo staking ETH doesn't have to be hard. What I did find difficult though, was finding a good step-by-step tutorial, including how each step should look like (what the logs should show when a given step is working properly, etc.). So I went through the whole process myself. And I created a video out of it, to show exactly how each step looks. What's covered: - The hardware for staking Ethereum (I went with NUC) - How to install an operating system on your hardware (Ubuntu) - How to fund your validator with 32 ETH - How to install, configure, and run execution client (Erigon) - How to install, configure, and run consensus client (Lighthouse) - How to make sure everything runs continuously, even after a restart - How to monitor your validator and create helpful dashboards with all the important stats And, by doing all of the above, how to earn your Ethereum staking rewards.
