Yesterday during the live broadcast, someone asked about the opinion on $LINK .

I have previously mentioned the opportunities in RWA (Real World Assets). There are still many technical challenges to overcome in this field, the most crucial being how to connect information between the real world and on-chain systems.

This leads us to a key component: the oracle. It serves as a bridge connecting on-chain and off-chain data, allowing smart contracts to access information from the external world. Oracles are used to solve this problem.

In reality, most of our transactions rely on centralized platforms like Taobao and Amazon for trust. If these transactions move on-chain, issues arise: who proves that the item is yours? How do we ensure that the asset is real and undisputed? What happens in case of a dispute? These issues of rights verification almost always require an oracle to address.

Currently, financial assets are the easiest to put on-chain because they are inherently virtual, such as stocks, bonds, and tokens, which do not involve physical delivery. However, putting real assets like property and gold on-chain involves complex factors such as ownership rights, mortgage status, and legal disputes, which cannot advance without an oracle. It’s like breaking a house into ten thousand tokens; it seems simple, but verifying ownership, mortgage status, valuation changes, etc., requires off-chain data support at every step.

Typical smart contract scenarios such as financial contracts, insurance, and stablecoins also heavily rely on oracle support: without access to prices, asset values can't be determined; without understanding real situations, it's impossible to judge whether to pay out claims; without knowing the market status of collateral, maintaining the collateral rate becomes impossible.

Oracles are the core infrastructure for the realization of RWA in blockchain. Without them, the on-chain world resembles an information island. The current mainstream approach is to operate oracles as off-chain systems, using independent nodes to fetch and verify data, then writing the results into the main chain, while also employing technologies like zero-knowledge proofs to ensure security and credibility. Oracles are the “information entry point” of blockchain. Without this entry point, most applications cannot truly function.

We have clearly explained the concept of oracles and why they hold such an important position in the future blockchain world. They are absolutely indispensable infrastructure for large-scale applications of blockchain in the future. LINK, as a leader in the oracle sector, is why I see great potential in it.
