BlackRock, JPMorgan, Goldman Sachs, and Fidelity are reportedly accumulating a scarce blockchain asset - one that gets burned with every transaction on what analysts are calling America's new financial grid. The Nasdaq has received SEC approval to move stocks onto blockchain rails, and BlackRock CEO Larry Fink dedicated his entire 2026 annual letter to this infrastructure shift. Blockchain analyst Andy Howard is calling this asset 'Digital Oil' - and says institutional buyers are already positioned.tc pixel
