In the world of crypto assets, Tellor (TRB) has a very interesting label—the DeFi community calls it the "insurance oracle" or the "last lifeline." But don't get it wrong; it’s not an actual insurance company, rather its technical design makes it a perfect fallback option for protocols facing extreme risks.

Simply put, this is a reliability issue. Currently, most DeFi or RWA protocols rely on a leading oracle as their primary data source—fast, automated, and efficient. But what happens if these mainstream providers encounter problems? Hacks, system failures, or even regulatory shutdowns of price feeds can cause the entire protocol to collapse. This is a single point of failure, with risks that are alarmingly high.

Why can Tellor serve as an "insurance" role? The core reasons are twofold:

**First is censorship resistance.** Tellor doesn’t require any official permission. As long as someone is willing to pay TRB tips, any node worldwide can manually upload data. In other words, as long as the internet is alive, even if global financial markets are blocked by various regulations, Tellor can still operate. This kind of resilience cannot be matched by traditional oracles.

**Second is the dispute mechanism.** It doesn’t prioritize speed but seeks "absolute accuracy." After data is on-chain, there is a challenge period during which anyone can challenge or initiate a vote to verify the data’s authenticity. This meticulous approach, though slower, becomes a moat during extreme market volatility (such as flash crashes).
