Updates on Google Wallet's ZK system. I've reached out to abhi shelat at Google and got the confirmation that the system described in the below paper was indeed deployed in Google Wallet. - Standard proposals and open source code are to be released. - The system makes the tradeoff to minimize changes to credential issuers and user mobiles devices but requires changes on the side of credential verifiers. - The system uses a custom-designed ZK system based on GKR + Ligero (pioneered at @ligero_inc) for fast ECDSA + SHA256 proving.

1/ Google announced that Google Wallet will be using "ZKP" to support "fast and private age verification". But wait, what type of ZKPs are they actually using?

Google introduced a way to prove your age with your google wallet using Zero-Knowledge Proofs (ZKP) (blog.google/products/googl…). This work was pioneered by Matteo Frigo and abhi shelat (eprint.iacr.org/2024/2010) and uses a clever combination of Ligero (designed by founders of @ligero_inc) and GKR. Here are some highlights:

Goldman Sachs just announced they'll launch THREE Tokenization projects on Ethereum. I wrote about this few months ago: "BlackRock's goal is to be the first mover onchain no matter if the fees are low or it might disrupt their business. If they don't, another will. This puts a LOT of pressure on everyone, especially an Investment Bank like Goldman Sachs. You don't participate, you lose clients. You participate, you lose revenue. So they decided to participate but either hide it or lie about it."

Goldman Sachs: "Our clients are not interested in crypto, it's worthless" They lie. But why do they lie? Ethereum is literally a nightmare for them because it destroys their margin. They earn a LOT with their fees. Goldman Sachs has 45 000 employees. They can't compete with an

After reading through research and comments on @StoryProtocol, my initial reaction is why would anyone use this I think the dispute aspect has been the greatest concern when it comes to copyright and IP. If you want to protect someone's property, you need to know that property belongs to who. But how do you know if something belongs to someone if that something is not tangible, yet only told by stories? Fundamentally there is no reason that anyone should trust the "dispute module" that Story Protocol proposes because the process will become an endless, pedantic argument between random nobodies when it is a totally open forum, or an institution making arbitrary decisions, which doesn’t really solve anything and has no right to decide what belongs to who anyways. Let's say I recorded a sound of a drum set. A kick, snare, cymbal, hi-hat, crash, cowbell, etc. Then I create a machine that can play these sounds when I press buttons. Assume like millions of people use this thing that I named as a "drum machine", eventually creating a unique niche of music out of it. I mean, like assume there are festivals, forums, a global community created due to this drum machine I invented. Now comes me, who actually was the reason behind all the drum sounds, demanding money from all the people who created music out of my drum machine. Some might say, "Hey this dude who created the unique sound of the drum machine should take credit!" On the other side there are people yelling "NO it's the creatives who used the drum machine to produce great music that should take more credit" But again, the guy who sold the drum set that I used to record all the sounds is now telling me that he actually owns everything. What if God came down and said he owns all the frequencies that were made by these drums? Who are you going to side with? Essentially everything will boil down to the ability to formulate bullshit stories to convince whoever decides the outcome of these disputes. Will they have a full-on jury trial to find out if a snare drum sound belongs to HumpLord42069 or RizzKing911? Who will represent them? DJ Khaled? Story time. In 1997, English rock band The Verve lost a legal battle, being ruled that their mega hit Bittersweet Symphony plagiarized The Rolling Stones 1965 song, The Last Time. The Verve lost 100% of rights to their song, and Mick Jagger and Keith Richards from The Rolling Stones were given full songwriting credits despite not contributing to the creation of the song itself. Now go listen to the two songs and tell me if that was a good call. Links here: Bittersweet Symphony: youtube.com/watch?v=1lyu1K… The Last Time: youtube.com/watch?v=gdFQtb… You would imagine, “Why did they even lose??” Because The Verve actually negotiated a license to use a five-note segment of an orchestral recording of a cover of a Rolling Stones song. You don’t get it right? Just listen to the song they sampled: youtube.com/watch?v=9Yrllf… This song is supposed to be a cover of The Rolling Stones, which The Verve sampled. So basically The Verve got sued because they actually had rights to sample a song that The Rolling Stones doesn’t even own. LOL Do you think any of these songs actually sound like each other? This case basically told the world that “Hey this chord progression and all melodies that can be possibly deviated from the composition is owned by The Rolling Stones!” Do you believe that is the case? It will be impossible to distinguish the owner of a sound, a style, a look, and even a story through Story Protocol. The attached image was famously known as “Pocahontas In Space” because when you substitute some details, the plot for Avatar becomes Pocahontas. Does Disney has the right to sue James Cameron for such blatant plagiarism? Now what about Star Wars, The Lord of the Rings, The Matrix, Harry Potter, Lion King? They all use The Hero’s Journey formula. Are these movies all rip offs of each other? But ultimately, who owns this formula? If nobody does, can I mint an NFT on the Story Protocol to be the first and go out sue everyone? Again, it depends on the ability to bullshit your way to make people believe something. Meaning you can own anything, while owning nothing. if the dispute process can’t be 100% accurate and 100% reliable, there is no point of creating another system that will produce arbitrary outcomes And I believe there will never be a system that can have 100% accuracy because all content is consumed by the individual. Let’s say I sing a cover song of Radiohead so well, that some people will listen to my cover of Radiohead only. How much did Radiohead contribute to make people listen to my cover? If I am the sole reason, does that grant me a part of the IP? Or simply because the song was written by Radiohead they take 100% rights? Even though I didn’t write the song, I produced the sound waves of the song, which are the actual physical medium that reached the listener’s ear drums, so wouldn’t it make sense to say that I contributed more than Radiohead in this narrow instance? The thing is, I can make up these type of claims, and nobody will be able to decide if it is sound logic or not because it just depends on what people feel. Meaning logic stands nowhere in the process of disputing whatever IP belongs to who. It’s just all feelings. Eventually, Mick Jagger and Keith Richards of The Rolling Stones returned the rights to Bitter Sweet Symphony to The Verve's Richard Ashcroft in 2019. The base assumption of Story Protocol to operate is to trust the protocol’s consensus as the source of truth. But what is the truth? Nobody really knows.

General observation from @ethcc is that VCs are incredibly bored. There just hasn’t been any innovation for the past few months — only more restaking, LRT, L2’s, AI, BTC L2’s with small differences with each other.

SUPERFLUID AIRDROP IS NOW LIVE! 🚨 Now that we have your attention - Traditional airdrops often lead to massive token dumps, crashing prices instantly. Here's how Superfluid solves the problem 👇

1/ We are excited to introduce the @ElectricCapital Crypto Market Map! The Crypto Market Map tracks 1,500+ projects in crypto. It contextualizes every major project in crypto by organizing projects into 6 tech layers & 137 categories. cryptomarketmap.org Let's explore 👇🏽

The airdrop meta in 2024: Users frustrated, protocol fundamentals declining. Key insights from @Delphi_Digital's "Do Airdrops Hurt More Than Help" report. Essential for users and a must-read for founders ↓

there has been so much self-hatred in ETH (esp the research community) it's unbelievable. Have met too many black-pilled ppl here at EthCC, not to mention on the timeline. I don't get why people genuinely fud ETH vs Solana UX, many L2 UX/devX today is objectively way better than Solana, and it's literally called the "rollup-centric roadmap" so was the plan all along. UX is def not great yet and far from onbaording next billion users, but the path is pretty clear with AA and authorization innovations on wallets and I'd say solid progress has been made. On apps, it's 120% true that within crypto we way overestimates the rate at which app innovation happens, but that should mean "we need to accelerate apps and try more experiments", not "make short-sighted decisions at the key infra layer." Sadly, a lot of current MEV research takes the existing app landscape as an axiom and design mechanisms based on it, instead of thinking from first principle and ask what fundamentally is causing the problem and solving that. Robust mechanism doesn't over-index on the past, but looks into the future. MEV is objectively a huge problem & it's hard. Market always solve incentive problems first because their impact is transparent. The meme of "everything is MEV" has stood the test of time. I've found so many gems of app ideas by just going back and read research papers published by e.g., IC3. We just need to try all of them and ship. ETH L1 is a long-term bet on decentralization, the value proposition is strong, and it's clear that's the direction where the future is headed. I wouldn't bet against the trends of history because of short term fluctuations, I would double down. And it makes sense to have division of labour and focus on decentralization with a "small government" structure. Internalized oppression is a VERY VERY real psychological effect and let's not go down that path... don't be like the black butler in Django Unchained, be the "Yes Chad" and double down on what you believed.

After 2+ years of building @rage_trade, we are launching $RAGE on @HyperliquidX. Over the last few years our team has been early to a few things in DeFi. We started building perps before any onchain perp had 'real' volume. We hoped that users would come, and when FTX collapsed... they did. We built real yield vaults using perps like @GMX_IO because we saw dollars leaving crypto (post FTX) for the risk-free yield on treasuries. Now @ethena has spearheaded this concept to billions in TVL. And now we are taking a big bet on @HyperliquidX. HL has two things that drew us to it: (1) a world-class product w/ real users and (2) an ecosystem unecumbered by insiders. As we announce more on the $RAGE token, you'll come to see how we intend on contributing back to the HL ecosystem. Better turn on your notifs anon...

Deep Diving Attestations - A quantitative analysis By: - Nero_eth 🔗 ethresear.ch/t/20020 Highlights: - Validators' attestation performance varies significantly, with some consistently performing better than others. -Attestation inclusion delay is a critical factor, with most attestations included in the next slot, but some experiencing significant delays. -Proposer timing games can negatively impact attestation performance, leading to more missed head votes. -Big blocks and blocks with many blobs tend to receive fewer attestations due to the increased data transmission time. -EIP-7716 proposes anti-correlation penalties to discourage validators from leveraging economies of scale, aiming to improve the overall health of the network. ELI5: This research dives into the performance of Ethereum validators by analyzing their attestation behaviors. It looks at how well different validators perform, the timing of their attestations, and the impact of various factors like MEV-Boost and proposer timing games on their accuracy.

As a founder - your job is marketing and sales first. This means that you should be thinking as much about communicating who you are and what you are working on as much as what you are building. Share publicly what you are working on and your updates, engage people in DMs, ask people to retweet or write about your project. Organize your own podcast and invite people to join it. Don’t go for the most famous person first - ramp it up by inviting people you know and you will have a good and interesting conversation and over time keep inviting more known people. Ask to join events to present your project, reach out to people who organize Spaces to talk about your project, join @pitchtalk_com and other platforms to present it to wider audience, etc. Hone in your story every time you are talking - adjust for the audience and learn from questions people ask.

Signal implements e2e encryption. On your end it has to decrypt the messages so that you can read them. Then it needs to store them locally. It encrypts them with a key that also need to be stored to decrypt the db... Using a Ledger to secure this key would solve everything!

This is the folder structure of Signal's local data on macOS. The encrypted database and encryption key are stored next to each other. The folder is accessible to any app running on the Mac. How could such a blunder be approved by an open-source project reviewed by many experts?
