When people hear the word "oracle," they often think of ancient fortune-tellers. This association isn't entirely wrong, as historically, oracles were consulted for guidance and information in ancient times. Similarly, oracles in smart contracts serve as information providers. Let's explore their function and importance in blockchain technology.
UNDERSTANDING ORACLES IN SMART CONTRACTS
Modern blockchain systems with smart contracts have an inherent limitation: they can't naturally access external data. This creates a significant barrier to their standalone functionality.
In the blockchain ecosystem, oracles act as bridges, channeling external information into the blockchain network. This functionality significantly enhances smart contracts' capabilities and applications.
Consider a smart contract designed to release payment only after goods delivery. The blockchain itself can't verify real-world delivery status. This is where oracles become essential, feeding this crucial external information into the smart contract.
This mechanism enables smart contracts to function across various sectors, including commerce, supply chain management, legal services, and location-based services, among others.
THE NECESSITY OF ORACLES FOR SMART CONTRACTS
The core issue lies in the fundamental difference between real-world and blockchain environments. Blockchains operate as deterministic systems with precise, ordered sequences. While this ensures data integrity, it also creates limitations.
In contrast, the real world operates non-deterministically. Though this creates transparency challenges, it offers greater flexibility and adaptability.
Direct integration of real-world data into blockchain would compromise its integrity. The structured nature of blockchain cannot directly interface with the chaos of real-world data. Thus, oracles are essential for smart contracts that interact with real-world conditions.
CURRENT APPLICATIONS AND FUTURE OUTLOOK
The oracle sector in smart contracts has evolved into a thriving industry, attracting numerous startups and developers. Major technology companies, including Microsoft and IBM, have shown significant interest in this technology.
The future may see the development of a comprehensive global platform enabling seamless interaction between smart contracts and real-world data across all levels. Current trends indicate growing interest and development in this direction.
