In the rapidly evolving landscape of Decentralized Finance (DeFi), reliable and real-time data feeds are the lifeblood of smart contracts and dapp.
RedStone, an innovative Oracle system, has emerged as a pioneering solution to address the challenges and limitations of traditional data delivery methods. By leveraging decentralized networks and a modular design, RedStone revolutionizes how data is sourced, aggregated, and delivered, ushering in a new era of trust and efficiency in DeFi protocols.
Unlike traditional Oracle systems that rely on centralized data sources and intermediaries, RedStone taps into the power of the Streamr network. This decentralized infrastructure allows data providers to deliver signed Oracle data to end users, eliminating the need for continuous on-chain data delivery. This approach not only conserves resources but also enhances the overall user experience by reducing latency and maintaining data integrity.
RedStone's modular architecture marks a departure from monolithic designs that inhibit scalability. The system introduces a novel data availability layer, where data is first placed before being fetched on-chain as needed. This revolutionary approach enables RedStone to broadcast a diverse array of assets at high frequency to a cost-effective layer, minimizing on-chain congestion and reducing operational costs. By marrying data availability with on-chain efficiency, RedStone ensures that only essential data reaches the blockchain, optimizing performance and scalability.
RedStone's data flow is a meticulously orchestrated process involving multiple sources, aggregation nodes, and cryptographic validation. Data feeds are sourced from a myriad of providers, including off-chain DEXs (Binance, Coinbase, Kraken), on-chain DEXs (Uniswap, Sushiswap, Balancer), and aggregators (CoinmarketCap, Coingecko, Kaiko). These feeds are aggregated in independent nodes operated by data providers, who utilize methodologies like median, TWAP, and LWAP, bolstered by safety measures such as outlier detection. Once cleaned and processed, the data is signed by node operators, attesting to its quality and authenticity.
End users play a pivotal role in RedStone's decentralized data delivery. Through a multi-step process, signed Oracle data is pushed on-chain, either by dedicated relayers operating under predefined conditions, bots executing liquidations, or end users interacting with DeFi protocols. Cryptographic verification within the protocol ensures that the data's origin and timestamps are valid, safeguarding the integrity of the information.
