Tomorrow, we publish a new The Edge Podcast with Robinhood GM of Crypto, Johann Kerbrat. This clip might be the clearest articulation I’ve ever heard on why Ethereum's roadmap is working, and why Robinhood chose to build its own L2 using Arbitrum. + Ethereum offers security, with proven decentralization + New L1s = centralized databases + EVM liquidity is essential for tokenized stocks & RWAs + Arbitrum’s tech stack wins on engineering merit No edits. No spin. Just a major U.S. fintech explaining why they’re building the future of finance on Ethereum. Real validation for those of us who are long term Ethereum/ETH investors. Here is the clip and transcript for Johann answering why Robinhood chose to build its own Ethereum L2: "You see a lot of companies right now building their own L1. And for us, we felt excited about this idea where we can control anything that we want to build and we don't have to deal with any other chain to talk to or anything like that. But at the same time, creating the security of a real proper decentralized chain is extremely difficult, as you know. And we basically get that for free with Ethereum. The network has been going on for a very long time now and the security is stable and it's decentralized. And I think that's really the key two points that we wanted to have. When you look at some of these new L1s that are being created, it's not really decentralized and it's not really secure. So at the end of the day, you're basically having like a... fancy database that is probably a bit slower to use than an actual database. And so we didn't really see the value in that. With Ethereum, we get the security by default. The second thing that we get by having an L2 is that you get all this liquidity that is already part of all the EVM compatible chains. And that was also a very important decision factor for us. If we really want to bring the stock market onto the chain, we need to have this liquidity. It's not going to be possible if it's in a closed loop or in a closed chain that nobody can access and you need to have like 20 different hoops before you can bridge to that chain. So for us, that was kind of the two elements that we really wanted to focus on and that's why we decided on building on Ethereum. And then we decided on Arbitrum mostly because we love the technology. There's a few things that we are excited about. For example, Stylus. It's a way that we can basically use different language into the chain and we can build on top of that. We also like the way that they prioritize transactions that is, we think, a better way than some of the competition. And so basically we'll use the Arbitrum stack and we'll create our own L2, which will make us also compatible with all the Arbitrum chains. And so we think it's kind of the best of all the worlds. But for us, the idea is like we will start with public stock, and then we think that we can tokenize anything really, not just stocks. It can be private stock, it can be art, it can be real estate, whatever you want to think of. And so we really wanted to have a platform that is kind of easy to build on and we can keep adding on it. At the same time, we know that regulation are going to be hard on some of these products, especially when it comes to financial products. You always have different regulators. You have different rules depending on the region. If you're in the EU versus the US versus LATAM. And so we felt like we wanted to have our own layer that we could customize for these needs. And then anyone that is building on the chain will also be able to benefit from what we are building, versus just putting everything in a contract that will be just good for the people that are using the Robinhood contracts. But so at this point, we announced the chain in June. We are in private test right now, and then we'll do more announcements in the future."

Etched is deploying two new technologies in chip design: low-voltage inference and cluster-scale memory. CEO Gavin Uberti says they'll make their chips much more power-efficient and way, way faster than today's leading GPUs. He breaks it down: "We looked at a lot of early research directions, and we realized the key things that models need are way more compute and way faster memory." "If you think about inference, there are two key parts: prefill and decode. For prefill, it's a compute-bound problem. You need to have more FLOPS, more operations per second on each of your chips." "On our GPU, the bottleneck's actually thermals. You can't really run a GPU at more than around 50% of what it could theoretically do, or it'll melt." "So we're using a new technology today called low-voltage inference to try to solve this problem. You bring the voltage of the chip down dramatically, which allows us to have way, way better efficiency in terms of how much power is drawn per unit of math, and thus fit way way more flops onto the chip..." "For decode, it's all about bandwidth. Not just bandwidth on a chip, but bandwidth across your cluster. That's why we have this technology we call cluster-scale memory. It reduces the amount of time it takes to communicate from one chip to another dramatically." "As a result we can go use all of our HBM, HBM bandwidth, SRAM, SRAM bandwidth, and our scale-up domain as a single coherent pool. And that means if you're a user, you can go get much faster tokens per second, while still keeping your costs low."

🔊 Elon Musk did a live phone interview earlier today with a guest host of the Sean Hannity radio program, discussing his latest SpaceX timelines. I only caught about the last 5 minutes of it: “The best way to expand compute is really in space. There’s a lot of room in space and if you look at the size of Earth relative to the sun or relative to the solar system, you realize just how tiny Earth is. We’re very, very tiny. We only receive about half a billionth of The Sun’s energy. So if you really think of Earth as being like a tiny dust mote in a vast darkness. So the way to expand compute— without, ya know, using up all the land on Earth— is to do so in space. And then you can do it without using up space for power & water on Earth. You can just do it in space, so… I think we will probably be launching our first AI satellites next year and then we will probably be able to do that, I think, at large scale in about two years. Yeah, well, I’ve always had the philosophy that everyone at the company should receive stock in the company so that they can participate in the upside of the company and it’s great for aligning incentives as well, so as the company prospers, then the people at the company— the employees — also prosper, so that’s just been, ya know, my philosophy from Day 1 is just to make sure everyone gets stock in the company, so there are, I think, several thousand people who’ve been – it’s not just one welder – it’s several thousand people who were, you know, working on the production line and started at the company relatively early… then probably their stock is worth over $1 million at this point “Yeah, so, Mars is much harder to get to than the moon and you can only travel to Mars roughly every two years. So Earth and Mars align such that you can travel to Mars only once every 26 months. So that makes it a lot harder than the moon where you can go to the moon pretty much anytime and it only takes a few days to get to the moon whereas it takes about six months to get to Mars. So that’s why we can do the moon faster than we can do Mars. But I think, probably, if things go well, we can probably send the first people to Mars in about five years, and then rapidly increase the cadence of sending people to Mars thereafter, so every two years we could dramatically increase the number of ships going to Mars and, ya know, hopefully in a 10 or 12 year timeframe we’ve sent thousands of people to Mars.”
