Why do blockchains and the real world need oracles?

Blockchains are excellent storage systems, where data is tamper-proofing,
encrypted, and verifiable. However, blockchains can neither access external
information nor decide whether the information is authentic and credible.
WINkLink uses its smart contracts to connect data from the real world, and
ensures data reliability through a decentralized mechanism.


WHAT DOES WINKLINK DO?

Feed trusted price data to DeFi platforms
Decentralized financial apps have to provide prices for token trading and loan
collateral. WINkLink's embedded price oracle system offers stable and reliable
price feeds to DeFi-building developers.
Provide trusted off-chain data for more use cases
WINkLink allows developers to use any real-world data such as sports and
weather. Developers can create customized oracles and connect smart contracts to
the real world in a few minutes.
Generate random numbers
WINkLink provides developers with secure and verifiable randomness so that
oracles can meet DApps' various needs for random numbers. The tamper-proof
nature of VRF random numbers improves the fairness of random number results.
Boost growth of TRON ecosystem
WINkLink's smart contracts can access any data easily, forming a trusted data
ecosystem in various industries. With faster, more stable, and cheaper
transactions, it provides better services for developers and users.
