The Area Chain Prophecies and their Importance for Smart Contracts

The block chain predictor is the infrastructure that connects the block chain with the outside world, whose decentrized financial (DeFi) security, which exceeds $200 billion, depends on its proper functioning. Smart contracts, although powerful, do not provide direct access to prices, weather data or validate bank account payments. The standard architecture of the predictor is divided into three levels: data acquisition, aggregation and chain delivery. The prognosis node connects external data providers, the polymer layer merges multiple data points into a single value, and the delivery layer incorporates the polymer value into a chain smart contract. The problem of prophecies is the fundamental tension in the design of the block chain, which cannot be fully resolved and can only be managed. Each decentralised financial agreement relies on price data provided by the predictor to ensure its liquidity and safety。
