Blockchain oracles have become an increasingly important component of decentralized finance (DeFi) protocols, allowing smart contracts to interact with data and external systems beyond the blockchain. Oracles act as intermediaries between off-chain data sources and on-chain smart contracts, providing reliable and timely data to inform smart contract execution. However, the existing oracle systems have limitations, such as the requirement for continuous on-chain data delivery, limited scalability, and lack of trusted sources and data update conditions.
Smart contracts and UTXO meet together in the ADA universe. A safe and transparent model, soon to be a swift network for transactions and smart contracts.
Arweave is a decentralized, permanent data storage that leverages blockchain technology, with its bright idea, blockweave and Proof of Access, to achieve this goal.
Layer-0s are becoming one of the most important part of the blockchain world. It is necessary for them to be fast and cheap. Venom Foundation tries to achieve this goal.
