FICO is a black box because opacity is the product. You can service every obligation on earth and still be a ghost if you never rented the right kind of debt from the right kind of bank. Credit was never “can you pay.” It was “did you already pay us.” Borrow. Repay. Repeat. That’s duration. That’s a track record. That’s the only input that should price the next loan. Reputation is working capital. The score should just be the receipt.

A bot that spent years robbing Ethereum traders just handed an attacker ~$7.5M. No hack. Voluntarily. This is JaredFromSubway... the most notorious sandwich bot on the network. How they did it: - Over several weeks, the attacker pre-seeded dozens of fake tokens and fake pools that looked like very fat trades to the bot. - The bot (which exists to hunt exactly those opportunities) approved spending its own real ETH, USDC and USDT... but it was only ever trading the fake tokens, so the approvals were never consumed and stayed open. - Then, in a single transaction, the attacker used them to pull out all the real money. Everyone called it poetic justice. A bot that sandwiched retail for years, suddenly the victim, and now offering a 50% white-hat bounty just to get some of it back. Robin Hood in reverse: it was robbing ordinary people the whole time. But here's the more interesting part. Nobody broke a contract or stole a key, they attacked the bot's judgment = the "this route looks profitable" it was built to act on... and that's a preview of every attack on the agent economy. Once autonomous agents start holding open allowances and moving real capital, the attack surface isn't the contract, it's whatever the agent reads as opportunity. Poison that, and it signs its own drain. And now the operator wants courts and law enforcement... i.e. doxxing himself to everyone he sandwiched for years. Code is law, right up until you're the one who got drained 😄

FIRE for everyone in trading and liquid asset management! A Vitalik proposal I'd advise you NOT to scroll past: index-tracking assets and synthetics built on options, instead of debt and liquidations. Worth stopping for: ethresear.ch/t/building-inde… The mechanics are simple... nothing new for anyone who's been around options, but the mechanics transform in the crypto world. - Split 1 ETH into two halves: P = the cash half, holds value up to the strike; N = all the upside above it. - Together they always equal exactly 1 ETH. Want stable exposure = hold P and roll into a new strike when price gets close, that's it... and now the chain that makes it all matter. Liquidation is impossible... and not because risk parameters are carefully tuned, but by construction: the two halves sum to exactly what was deposited at any price. How do we get around the Oracle? Exactly like this. Because if there are no liquidations, no real-time oracle is needed. You need a price once, at expiry, and real-time oracles are the weakest point of the entire on-chain stack: making them safe is nearly impossible, and whole protocols have burned on that attack vector. I wrote after the Polymarket episode: the best on-chain primitives are still being built. This is exactly that. A primitive that's fine with a slow, verifiable oracle. Perps took the liquidity and the attention, but they stand on the same fragile stack: debt, liquidation, fast oracle. A liquidation cascade in every stress event isn't a glitch. It is, unfortunately, a property of the foundation. Implementations are already on testnets, and Vitalik himself says "it's happening" and insists on formal verification before mainnet. After the Orchard bug in Zcash, that's no longer just caution, it's a lesson learned and a necessity. We ran formal-verification research once, and I really regret that back then, early in my crypto journey, I didn't have the budget, and we paused the research. Anyways... Either way, this still isn't about "ETH up tomorrow," it's about whether on-chain exposure becomes acceptable to the capital that's been sitting out... cos it didn't want to depend on fragile oracles or catch someone else's cascades. Options are a huge part of derivatives markets in TradFi. So if, as Vitalik writes, it's finally taking off... that's great for everyone. Serious money will come as soon as we remove from the foundation the thing that kept breaking.
