Bankless
Synthetix perps on Ethereum layer one and execution model
They explain Synthetix's Ethereum L1 perp DEX design using a centralized matching engine that batches to L1 for settlement.
In this week’s Weekly Rollup, we break down “Downtemper” market moves as Bitcoin and Ethereum slide, and examine why Vitalik Buterin is calling low-risk DeFi Ethereum’s true backbone. We highlight Tether’s ambitious $500B raise, Polymarket’s mainstream moment on South Park, and Gary Gensler’s testy CNBC appearance. We also cover Paul Atkins’ push for pro-crypto regulation, the heated debate over whether Base should be regulated like Nasdaq, and the surprising deletion of 86 million bank accounts in Vietnam as digital ID mandates expand.
