The battle of decentralized Oracles.
Decentralized Oracles connects smart contract to any piece of data and provide stronger security, but still can be attack. It can process more complex data than smart contract.
Chainlink (LINK) is a decentralized oracle network which aims to connect smart contracts with data from the real world. In Chainlink's case, the oracles are connected to the Ethereum network. Oracles provide external data (e.g. temperature, weather) that trigger smart contract executions upon the fulfillment of predefined conditions.
LINK CMCDIA (Decentralised Information Asset) claims to provide financial institutions with an immutable and verified single source of financial market data for any market and asset type. DIA also claims to be an open-source, data and oracle platform for the DeFi ecosystem.
DIA CMCBAND (Band Protocol) is a cross-chain data oracle platform that is able to take real-world data and supply it to on-chain applications, while also connecting APIs to smart-contracts to facilitate the exchange of information between on-chain and off-chain data sources.
BAND CMCWhat do you think the best decentralized oracle in the long run?
