Oracles are one of the most significant protocols of the blockchain industry that keep the sector running using oracles. The primary function of oracles is to supply real-world and real-time data to distributed ledger technology and smart contracts because they cannot acquire data independently. Decentralized oracles were introduced to address the oracle problems plaguing the blockchain ecosystem. A decentralized oracle or decentralized oracle network (DON) is a network of autonomous blockchain oracles that feed data to a blockchain. The decentralized oracle network’s nodes and oracles each independently retrieve and bring data onto the chain from an off-chain source. The data is then aggregated for the system to determine a deterministic value of truth for that data point. Oracle problems are resolved via decentralized oracles. Despite the recent crypto crisis, Oracle cryptocurrency projects remain a popular investment option. In this article, we take a look at the top 5 Decentralized Oracles Crypto Projects. QED QED protocol is built on the DelphiOracle. With its strong economic foundation, this decentralized oracle aims to close a gap in the crypto industry. It links several blockchains, off-chain data sources, and platforms for smart contracts. Its security, accuracy, resilience, and complete decentralisation make QED the ideal alternative protocol. Compared to comparable oracle protocols like Chainlink, which have an aver...
