Paralink Link is a real-world data ingress for cross-chain applications. Its purpose is to collect, validate, aggregates, and interpolate real-world datasets and feed them into smart contracts on Ethereum and Polkadot.
Paralink's flexible node design allows developers to query data including real-world events, sports, weather, random numbers, and more. Developers can create custom queries using Paralink Query Language and connect smart contracts with traditional web APIs within minutes.
Applications that require the highest degree of security can use Paralink on-chain consensus algorithm, running on Polkadot Substrate. This makes the coordination much cheaper than performing the same computation on Ethereum. Paralink entropy as a service provides high-quality hardware-based randomness.
