Blockchain technology has been a game-changer in many industries, offering a level of security, transparency, and efficiency that traditional systems cannot match. The real magic behind blockchain’s transformative power lies in “Smart Contracts.” These self-executing digital agreements, which automatically enforce themselves when certain conditions are met, are the cornerstone of decentralized applications (dApps). However, the smart contract landscape is evolving, ushering in a new era of “Hybrid Smart Contracts.” These advanced contracts blend on-chain code with off-chain data, provided by decentralized oracle networks (DONs), to unlock greater capabilities and potential use cases.
Decoding Hybrid Smart Contracts
Hybrid Smart Contracts are the brainchild of the marriage between on-chain blockchain infrastructure and off-chain data, fueled by decentralized oracle networks. The term ‘hybrid’ signifies the amalgamation of two elements, while ‘smart contract’ resonates with its blockchain origins.
These smart contracts are unique in their capacity to process off-chain data while retaining the decentralization that characterizes blockchain networks. This dual functionality enables the development of more sophisticated blockchain-based applications, thereby broadening the scope of possibilities within the blockchain landscape.
The mechanics of a hybrid smart contract involve a data request from the blockchain to the DON whenever off-chain data is needed. The oracle smart contract within the DON retrieves this data and logs the corresponding request details. The log event informs off-chain nodes, which are then responsible for gathering data from the log event, verifying it, and delivering it back on-chain for smart contract use.
The Anatomy of Hybrid Smart Contracts
A Hybrid Smart Contract app comprises two main components:
- Smart Contract: This refers to the code that exclusively runs on the blockchain.
- Decentralized Oracle Network(s): These are secure off-chain services that support the functioning of the smart contract.
These two components work in harmony, forming a unified hybrid smart contract application. The result is on-chain code that gets a power upgrade through a range of unique and vital ways, thus opening up numerous new applications that were previously unreachable due to technical, legal, or financial constraints.
Hybrid smart contracts are designed to synchronize two distinctly different computing environments, thereby creating an application that is superior to what a blockchain or oracle network could achieve independently. This is primarily because each environment specializes in offering features that the other lacks.
On-chain code operates in an extremely secure and limited-functionality blockchain environment, minimizing the attack surface area and ensuring that the code runs precisely as written. On the other hand, DONs operate off-chain, offering greater flexibility in functionality and data accessibility.
Chainlink: Powering Hybrid Smart Contracts
Chainlink is a decentralized oracle network that has been instrumental in enabling the full potential of smart contracts. It provides a secure and reliable bridge for smart contracts to interact with real-world data and services outside the blockchain’s native environment.
Chainlink operates on a model that is almost identical to that of a blockchain, relying on a network of independent entities (oracles) to collect data from multiple sources, aggregate it, and deliver a validated, single data point to trigger the execution of smart contracts. This approach reduces any centralized point of failure and enhances the reliability of the data used to execute smart contracts.
An excellent illustration of how Chainlink functions is its provision of the USD price for Ethereum’s cryptocurrency ETH to blockchains through the ETH/USD Price Feed. This feed requires several independent oracle nodes and data sources to collect and deliver the price data.
Five Groundbreaking Use Cases for Hybrid Smart Contracts
1. Market Data for Decentralized Finance (DeFi)
The hybrid smart contract model forms the backbone of a large portion of the DeFi industry. DeFi aims to recreate traditional financial systems and products, offering enhanced flexibility, speed, and security. Most DeFi applications, such as lending platforms like Aave and Compound, rely on an oracle network to fetch, validate, and deliver aggregated data from the real world. This data then determines how smart contracts execute and settle on blockchains.
2. Weather Data for Parametric Insurance
Hybrid smart contracts can also be used to create interesting applications that can significantly improve people’s lives. Decentralized oracle networks can now deliver weather data onto blockchains from trusted sources, enabling the development of parametric insurance contracts that automatically pay out when certain weather conditions are met.
3. Satellite Data for Regenerative Agriculture
Hybrid smart contracts can interact with the real world, incentivizing important behavior. For example, the Green World Campaign uses hybrid smart contracts that rely on satellite imagery to reward individuals who help regenerate agriculture on critical tracts of land.
4. Dynamic Non-Fungible Tokens (NFTs)
The first generation of NFTs was static, but the hybrid smart contract model could completely transform the next generation of these assets. By using oracle networks, smart contract developers can create “Dynamic NFTs”, or NFTs that can automatically change when something happens in our real world.
5. Randomness in Gaming
Blockchains cannot securely generate randomness by their nature. As a result, many blockchain applications that rely on random number generation are often hacked or exploited. To overcome this limitation, popular blockchain games use oracles to generate random numbers backed by a cryptographic proof using a Verifiable Randomness Function (VRF).
The Impact of Hybrid Smart Contracts on the Blockchain Industry
The popularity and widespread use of hybrid smart contracts have opened new avenues for DeFi developers. Instead of creating a secure infrastructure to source price data for their smart contracts, they can focus on building their products and simply plug into an existing decentralized oracle network for their data when ready.
The use of hybrid smart contracts is not confined to DeFi. This model has been used to develop all kinds of engaging applications aiming to improve people’s lives. In general, the ability of these decentralized oracle networks to perform more complex computations will allow smart contracts to perform more tasks, offering a better user experience and easier and more efficient processes across blockchain that have long been limited by the code.

What are hybrid smart contracts?
A hybrid smart contract comprises a smart contract and decentralized oracle networks. It is a code running exclusively on the blockchain, on-chain. And decentralized oracle networks refer to secure off-chain services supporting the work of smart contracts.
How do hybrid smart contracts differ from traditional smart contracts?
While the smart contract is a code running exclusively on the blockchain, on-chain, hybrid smart contracts (decentralized oracle networks) are secure off-chain supporting smart contracts. This way, hybrid smart contracts combine on-chain information and off-chain data.
