From re-staking to the AI data layer, OpenLayer provides trusted data for on-chain and off-chain apps.

Crypto VCs are still investing in the AI sector. On November 20, the crypto AI startup OpenLayer, co-founded by three former Robinhood employees, completed a $5 million seed round financing. Investors include a16z CSX (crypto startup accelerator), Geometry, IOSG Ventures, Spartan Group, LongHash Ventures, and angel investors from projects like EigenLayer and AltLayer. OpenLayer was also one of the selected participants in the spring startup accelerator announced by a16z crypto in March this year.

AI Data Layer

Initially, OpenLayer served as an AVS service on EigenLayer, attracting over 48,000 stakers with a staking value exceeding $10 billion. However, OpenLayer is not satisfied with just being an AVS service. In its latest official introduction, OpenLayer is described as a modular trusted data layer that combines optimistic execution, cryptographic verification, and decentralized physical infrastructure, aiming to provide trusted data for on-chain and off-chain apps.

The project enables users to contribute and verify data through a Chrome extension and earn points, while developers can access this data for AI model training and other scenarios with user consent.

Previously, the project also received grants from the Ethereum Foundation, Optimism, and Arbitrum.

Architecture Design

OpenLayer acts as an AI data layer, allowing users to contribute and verify data and earn points through a Chrome extension. According to its website, application developers can access this user data with user consent, thereby protecting privacy. Use cases include training AI models, user localization, and enhancing functionalities.

OpenLayer's service use cases include various types:

• Apps that require accurate and real data input
• AI model training that obtains legitimate data from online and offline sources
• Companies that wish to leverage user identities and reputations from other existing platforms to guide their platform

OpenLayer connects data supply and demand, providing modular solutions to coordinate data collection, verification, and transformation, allowing for flexible combinations between sources, users, and specific verification methods.

In terms of interoperability, OpenLayer integrates various interoperability solutions such as Avail, NodeKit, LayerZero, etc., ensuring that our data solutions automatically cover as many clients as possible.

The OpenLayer ecosystem will include roles such as data users, requesters, node operators, and validators, all operating alongside OpenLayer and re-staking (EigenLayer).

Users specify a symbol and publish requests as tasks to OpenLayer's smart contracts, and when the tasks are completed, they can read the results from the smart contracts. Node operators perform actions to start providing data to OpenLayer.

For certain types of tasks, each operator will return different results. The operator type (aggregator) generates consistent results based on standard aggregation results. Notary services act as witnesses on one end to confirm that operators have actually made API calls and have not reported random information to the oracle. Validators are the guardians of the ecosystem. They monitor new tasks and task responses from node operators.

Point Earning

OpenLayer co-founder Jiang, who is also a former technology lead at Robinhood, revealed that the protocol will issue tokens in the future, and the current point activities may be redeemable for tokens later. Users can earn points by installing the OpenLayer extension on Google Chrome and logging in with their connected wallets in three ways.

The first way is to click on eggs to collect points, with a maximum of four feedings per day. The second way requires connecting a Coinbase wallet and completing registration with a Twitter account to earn points. The last method is the common invitation mechanism.

Currently, some social networks, gaming, and AI companies are using OpenLayer to query and utilize verified user data, while OpenLayer charges for this access to ensure revenue.
