How do we build a decentralized index that stands on its own—one that doesn't rely on any single fiat currency as its anchor? That's the real puzzle.

Then there's the oracle problem. Blockchains need "eyes" to see the external world, but these oracles have a weakness: they're exposed to what we might call "financialized governance attacks." When economic incentives get tangled up with decision-making power, oracles become capture targets. The tougher the oracle resistance against manipulation, the more critical it becomes to solve this challenge head-on.
