What is API3?

API3 is a decentralized API infrastructure that allows smart contracts to interact with real-world data in a secure and reliable way. Its architecture leverages the concept of Airnode, a decentralized oracle node that acts as a bridge between the smart contract and off-chain data sources. API3’s first-party oracle model eliminates the need for third-party intermediaries, and its use of a crypto-economic guarantee ensures the reliability of the data provided. With its trustworthy and tamper-proof architecture, API3 is poised to become a major player in the development of decentralized applications across a variety of use cases, such as DeFi, gaming, and insurance.

History of API3

API3 was founded in 2020 by a team of experienced blockchain developers and entrepreneurs, including Heikki Vänttinen, Burak Benligiray, and Eray Sabancilar. The team noticed a critical issue with existing oracle solutions, which relied heavily on centralized third-party services that could be easily manipulated or tampered with. To address this problem, the team developed a decentralized oracle solution that would ensure the security and reliability of off-chain data sources.

In November 2020, API3 launched its initial coin offering (ICO) and successfully raised $6.5 million in funding. The funds were used to further develop the platform and expand its partnerships with other blockchain projects. In early 2021, API3 announced a partnership with Chainlink, a leading decentralized oracle provider, to collaborate on the development of more secure and reliable oracle solutions.

Today, API3 is one of the most promising projects in the decentralized oracle space. Its unique architecture, which leverages the concept of Airnode, has received praise from the blockchain community for its ability to provide trustworthy and tamper-proof data sources. With its growing list of partnerships and use cases, API3 is poised to become a major player in the development of decentralized applications in the years to come.

How does API3 Work? Guarantees and Low-cost

API3 leverages a unique architecture to provide a decentralized infrastructure for APIs that allows smart contracts to access off-chain data. At the heart of API3’s architecture is the Airnode, which is an oracle node that acts as a bridge between the smart contract and off-chain data sources. Airnodes are operated by a decentralized network of nodes that run on API3’s blockchain, ensuring that the data provided is trustworthy and tamper-proof.

Airnodes use a “first-party oracle” model, meaning that the data source itself is responsible for providing the data to the smart contract. This model eliminates the need for third-party intermediaries, reducing the risk of manipulation or tampering. Additionally, Airnodes use a “crypto-economic guarantee” to ensure the reliability of the data provided. This guarantee is backed by API3’s native token, which is used to incentivize node operators to provide accurate and timely data. The result is a secure and reliable API infrastructure that allows decentralized applications to access off-chain data sources in a trustless manner.

Crypto-economic guarantees

API3’s crypto-economic guarantee is a key feature of its architecture that incentivizes node operators to provide accurate and timely data to smart contracts. The guarantee is backed by API3’s native token, which is used to incentivize node operators to provide reliable data by rewarding them for accurate data and penalizing them for inaccurate or delayed data. This creates a strong economic incentive for node operators to act in the best interests of the network, ultimately ensuring the reliability of the data provided.

The crypto-economic guarantee used by API3 is unique in that it is tailored specifically to the needs of decentralized API infrastructure. By incentivizing node operators to provide accurate and timely data, API3 ensures that its infrastructure is secure and reliable, reducing the risk of fraudulent activity. Additionally, the use of a native token ensures that the incentives are aligned with the interests of the network as a whole, creating a self-sustaining ecosystem that can continue to provide reliable API services for years to come.

Low cost

API3’s decentralized infrastructure is designed to provide real-world data to smart contracts at a significantly lower cost than traditional centralized solutions. This is because the use of a decentralized infrastructure eliminates the need for third-party intermediaries, such as data providers and data aggregators, which can significantly reduce the cost of accessing data. Additionally, API3’s architecture is designed to be highly scalable, which further reduces the cost of accessing real-world data.

Another factor contributing to the low cost of API3 is its use of a native token, which is used to incentivize node operators to provide reliable data. By using a native token, API3 ensures that the incentives are aligned with the interests of the network as a whole, creating a self-sustaining ecosystem that can continue to provide reliable API services at a low cost for years to come.
