Oracles are a very important feature in blockchain, but I find that there is not much discussion about them; perhaps most people are not familiar with them. The function of an oracle is to write external information into the blockchain, achieving data communication between the blockchain and the real world.
The explosion of popular sectors such as RWA, AI, and DePIN also requires the functionality of oracles, which has also driven the development of the oracle sector. For the RWA sector, securely and accurately transmitting real-world asset data, such as real estate values, stock and gold prices, to the chain is crucial, and this process relies on the participation of oracles, which serve as a bridge between off-chain and on-chain data, ensuring the timeliness and reliability of the data.
Moreover, AI projects in the crypto market also need access to off-chain data for learning and reasoning, and oracles are a key component in this process, allowing AI systems to obtain real-time data from off-chain and execute corresponding operations on the blockchain.
With the development of RWA, AI, and DePIN sectors, the oracle sector is also rising, undoubtedly opening up the market value space for oracle projects.
Currently, the three leading blockchain oracle projects on the market are Chainlink, RedStone, and Pyth. Today, we will focus on introducing the similarities and differences among the three.

Introduction to Chainlink, Pyth, and RedStone Projects
Chainlink is undoubtedly the leader in the oracle sector, a well-established project since 2017, supporting mature EVM blockchains. As a traditional oracle, Chainlink uses a third-party oracle solution (PUSH), with third-party operators hosting the oracle nodes, aggregating external data provided by API providers, and inputting it into smart contracts.
Pyth is primarily based on the Pyth Network's own chain on the Solana public chain, with a core mechanism of Pull Price Update Model (PUSH), updating only when required. Compared to traditional oracles, it has significant advantages in update speed, asset coverage, and accuracy (high fidelity).
RedStone Oracles is a next-generation oracle provider that offers timely, reliable, and secure data sources for over 100 decentralized applications (dApps). It also provides data sources for layer 1 and layer 2 expansion solutions within the entire blockchain ecosystem, compatible with both EVM and non-EVM. RedStone adopts a modular architecture, integrating both Chainlink and Pyth models while supporting both push (PUSH) and pull (PULL) modes.
2. Comparison of Different Features of Chainlink, Pyth, and RedStone 🆚 Overview
3. RedStone's Unique Innovations
3.1 Modular Architecture: Push + Pull Dual Mode, Adapting to All Needs
RedStone Oracles is the industry's first dual-mode architecture that combines Push (push) + Pull (pull).
Push Mode: Suitable for the DeFi ecosystem, ensuring data is automatically updated regularly, suitable for traditional smart contract needs.
Pull Mode: Suitable for high-performance Dapps, retrieving data only when needed, avoiding unnecessary Gas consumption.
👉 This flexibility allows RedStone to serve different types of blockchain applications, rather than being limited to a single architecture like Chainlink (which can only Push) or Pyth (which can only Pull).
3.2 Gas Fee Optimization, Reducing Operating Costs by 50%+
Currently, on traditional oracles like Chainlink, each data update incurs Gas fees because data is periodically written to smart contracts. RedStone, however, utilizes a unique offline storage + on-demand retrieval mechanism, allowing data to not be stored in contracts by default, thus saving a significant amount of Gas fees.
Comparison:
Chainlink: Oracle nodes must regularly go on-chain, leading to high Gas fees.
RedStone: Data is first cached off-chain, retrieved only when the contract is called, saving more than 50% in Gas costs.
👉 This is a huge cost optimization point for DeFi protocols, especially for projects that require high-frequency data updates.
3.3 True Cross-Chain Oracles, Supporting EVM and Non-EVM
Most oracles primarily focus on the EVM ecosystem (such as Ethereum, Polygon, etc.), while RedStone not only supports EVM-compatible chains but can also extend to non-EVM ecosystems like Solana, Near, and Cosmos, which is unique in the current market.
Comparison:
Chainlink: Primarily supports EVM chains, relying on CCIP for cross-chain.
Pyth: Uses Wormhole for cross-chain transmission but is limited to specific markets.
RedStone: Seamlessly supports EVM & non-EVM ecosystems with greater scalability.
👉 This means that regardless of which chain your project is deployed on, RedStone can provide seamless oracle services.
3.4 Flexible Customization Capability to Meet Different DeFi Needs
RedStone provides a modular SDK that allows developers to customize data sources, update frequencies, Gas optimization strategies, etc., enabling DeFi projects to adjust oracle parameters according to their own needs rather than passively adapting to oracle rules.
Example:
A certain lending protocol may need to update price data every 5 minutes but does not want high Gas fees → It can use RedStone's Pull mode to retrieve data only when needed, thus saving costs.
A cross-chain DEX requires real-time synchronization of multi-chain prices → RedStone offers EVM + non-EVM cross-chain capabilities to ensure price consistency across all chains.
👉 This personalized customization capability makes RedStone more flexible than traditional oracles, able to match the needs of different DeFi ecosystems.
Currently, RedStone's Gas-efficient data sources cover over 50 chains and Rollups, securing a value of over $6 billion. Trusted by over 100 projects, including Morpho, Venus, and Pendle. If you are a DeFi developer, cross-chain protocol, NFT valuation platform, or derivatives exchange, RedStone Oracles can provide lower-cost, more efficient solutions.
