tellor/decentralizedOracle
You are only as decentralized as your data
Blockchains cannot natively access off-chain data (like API feeds or transaction data from another chain), so web3 projects have relied on their own methods of sourcing real-world data for their smart contracts.
However, centralized points of on-chain data entry are increasingly vulnerable to manipulation, attack, and censorship – making a truely decentralized oracle a critical piece of web3 infastructure.
For an oracle to claim it is truly decentralized, the provided data needs to be protected & validated by an unrestricted, distributed network of anonymous reporters and secured with simple crypto-economic incentives. This way any kind of data can be provided by anyone… and checked by everyone.
