They measure what the industry can service, and better infrastructure for verifying and governing assets may redraw that line. - [Provenance Before Tokens: Why Blockchain Can't Fix a Broken Chain of Trust](https://josephkaufman.xyz/writing/provenance-before-tokens/) (tokenization, 2026-11-08): You can put a lie on a blockchain and it is still a lie.
