What is a price oracle Crypto?
Price oracles are a bridge between the real world and the network, providing the information needed for smart contract execution. Oracles can be further categorized into off-chain and on-chain, centralized and decentralized. The biggest benefit of price oracles is the number of new blockchain use cases they introduce.
Can chainlink solve the oracle problem?
Chainlink has solved the oracle problem of smart contracts by creating a distributed pool of oracles, in each of which the oracles all strive to produce high-quality information. Smart contracts that take advantage of a decentralized pool of oracles improve their reliability.
What is the best crypto oracle?
