"I want to leave a safe world for my kids. This is what I got." Bryon Hargis (@hargsb) is the founder and CEO of @Castelion, a defense startup building hypersonic missiles the way SpaceX builds rockets: fast, iteratively, and cheap enough to produce in quantity.  His conviction is that America does not have a weapons problem. It has a manufacturing and learning rate problem. And that gap is more dangerous than any single technology demonstration.

Our new report "ETHGas: Enabling Realtime Ethereum" is live now! Ethereum's scaling problem isn't only about compute. It's about how blockspace gets allocated. Every 12 seconds, validators auction off the next block. Searchers pay priority fees to frontrun and sandwich users, earning validators roughly $350M a year while users absorb the cost in worse fills. Think of a highway where every car stops at the same toll booth. Adding lanes doesn't fix the bottleneck. ETHGas turns blockspace into a market where validators sell commitments directly to users. Buyers can lock in preconfirmations up to 64 slots ahead. Within each slot, transactions get ordered continuously across 240 sub-intervals of 50ms. That cuts MEV by an estimated 91% and delivers soft confirmations every 50ms, a 240x latency improvement over the current 12 second block. Ethereum becomes roughly 8x faster than Solana and 10 to 40x faster than most L2s on state updates. 240 price discovery loops per block opens Ethereum to HFT for the first time. Prop AMMs become viable, LPs keep more of each trade, and sandwich attacks get priced out of the system. Uniswap earns $1.2B a year in fees today. Realtime Ethereum projects another $2.4B on top. Users have migrated to Solana, Hyperliquid, and L2s under the premise that decentralization was worth the latency cost. If ETHGas works, that tradeoff collapses. Ethereum finally competes on execution, and its security and decentralization guarantees become a moat no other chain or perp DEX can replicate. The real scaling unlock is blockspace coordination.
