You may not have noticed yet, but a profound transformation is underway. It's not just about Bitcoin price fluctuations, but traditional financial giants like BlackRock and Franklin Templeton starting to put real assets on-chain and letting oracles "speak."

This is fundamentally a rewrite of the trust problem. In traditional finance, asset verification relies on audit reports and bank statements; in the on-chain world? Everything must become immutable, verifiable data on the blockchain in real time. The work being done on Arbitrum by some teams is building this "trust bridge"—not simply migrating old data, but fundamentally changing how assets are recognized.

**From "Snapshots" to "Live Streaming"**

Traditional fund net asset value (NAV) updates are delayed, audits are periodic, and investors see outdated "snapshots." But with RWA on-chain, it's different. Every tiny change in the underlying assets' value must be reflected on-chain in real time, verifiable by anyone. This is no longer just data transfer; it's about "translation" and "verification"—transforming unstructured data like PDFs, spreadsheets, and bank statements into data streams that smart contracts can read and trust through OCR, NLP, and cross-chain verification.

**Why is "real-time proof" more critical than "post-hoc audits"?**

The real risk in RWA projects isn't technical vulnerabilities but opacity in reserves. This is precisely the core issue that oracles need to address.
