Bridging the Gap Between On-Chain and Off-Chain Worlds
...Oracles: Bridging the Gap Between On-Chain and Off-Chain Worlds 1. Introduction Oracles are essential in the blockchain ecosystem, serving as the bridge between on-chain and off-chain worlds. Without oracles, blockchain applications would be isolated, unable to interact with real-world data. Their importance continues to grow with the rise of decentralized finance (DeFi), NFTs, insurance, and ......

Bridging On-Chain and Off-Chain Worlds: How Decentralized Oracles Work
...Decentralized oracles serve as secure middleware to bridge on-chain and off-chain environments. They allow blockchains to access external data to power real-world use cases like supply chains, decentralized finance, insurance and more. This article explains what oracles are, the oracle problem in blockchain, different types of oracles, and how they enable advanced hybrid smart contracts....

Proxy smart contracts for zero trust architecture implementation in ...
...Implementation of blockchain is quickly finding popularity in several real-world applications. As a result, in order to execute and process smart contracts, blockchains frequently necessitate integrating them with real-world data from various sources or employing third-party services. Through hybrid smart contracts, Decentralized Oracle Networks (DONs) make it possible for on-chain code to ......

Cross-Blockchain Communication Using Oracles With an Off-Chain ...
...Therefore, we propose an oracle with an off-chain aggregation mechanism based on Zero-Knowledge Succinct Non-interactive Arguments of Knowledge (zk-SNARKs) to facilitate cross-blockchain communication. The oracle queries data from another blockchain and applies a rollup-like mechanism to move state and computation off-chain....
