The Data Portability Layer or Application Layer is an open data playground for Data Contributors and developers to collaborate and build applications with the data liquidity amassed by DLPs. As the Data Liquidity Layer verifiably brings data onchain, the Application Layer provides the infrastructure for the distributed training of user-owned foundation models and the development of novel AI dApps.
The Application Layer functions as an active data hub, where online communities can collaborate with developers to create real economic value from their data. This fosters an interactive data creation ecosystem, where data contributors benefit from the downstream network effects and value emerging from the intelligence that their data helps to create.
The Data Liquidity Layer is where data is contributed, validated, and recorded to the network into data liquidity pools (DLPs). Here, DLP creators deploy DLP smart contracts with specific data contribution objectives, including the DLP’s purpose, validation method, and data contribution parameters.
In the Data Liquidity Layer, data contributors and custodians submit data to DLPs for validation and receive both governance rights and rewards for their data contributions based on parameters set out in the DLP validation process.
The purpose of the Data Liquidity Layer is to bring data onchain and facilitate data transactions among Data Contributors, Custodians, and DLP Validators. This network layer organizes all data collection and management for user and developer accessibility throughout the ecosystem.
The Connectome is a decentralized ledger of real-time data transactions throughout Vana’s ecosystem. Using proof-of-stake consensus, Connectome propogators propagate data transactions within the network. This ensures that DLP token transfers are valid and allows for cross-DLP data access by user-owned data applications.
The Connectome allows external parties to view and monitor data transactions throughout the network. Moreover, the Connectome is EVM-compatible allowing for interoperability with other EVM networks, protocols, and DeFi applications.
Vana is a decentralized network enabling global data creation and advancing AI innovation within an open data economy.
The network relies on three key concepts.
Vana consists of a Data Liquidity Layer, designed to introduce data on-chain as transferable digital assets, and an Application Layer (the so-called Data Portability Layer) for user-owned data applications powered by verified data. The universal connectome is a permissionless, real-time map of data flowing through the ecosystem.
Collective, pooled data is much more valuable than individual data as it can be used as AI training data. The Data Liquidity Layer facilitates the contribution, validation, and recording of data into Data Liquidity Pools (DLPs) via smart contracts.
DLP creators set specific objectives, including the purpose, validation method, and contribution parameters. Data contributors and custodians submit data for validation, receiving governance rights and rewards based on the DLP's parameters.
The primary goal is to bring data onchain, enabling transactions among Data Contributors, Custodians, and Validators, thereby organizing data collection and management for user and developer accessibility within the ecosystem.
Data Liquidity Pools (DLPs) aggregate similar types of data submitted to the data liquidity layer by Data Contributors and Custodians. Each DLP is an individual peer-to-peer network that uses DLP Validators to ensure data integrity through Vana’s proof-of-contribution system. DLPs provide trustless, private, and attributable data liquidity pools from which users and developers can:
Govern the use of their data in model training and application development.
Build community-focused applications in Vana’s application layer.
Sell data liquidity access to Data Consumers for model training.
The Data Portability Layer, or Application Layer, is a collaborative space for Data Contributors and developers to build applications using data from DLPs. It provides the infrastructure for training user-owned models and developing AI dApps. This layer acts as a hub where online communities and developers create economic value from data, fostering an interactive ecosystem. Data contributors benefit from the network effects and value generated by the intelligence derived from their data.
The Connectome is a decentralized ledger that records real-time data transactions in Vana’s ecosystem using proof-of-stake consensus. It ensures valid DLP token transfers and enables cross-DLP data access for user-owned applications. External parties can view and monitor these transactions. The Connectome is EVM-compatible, allowing interoperability with other EVM networks, protocols, and DeFi applications.
Bring your data and models across applications
With Vana, you can bring your own models and private data across applications. You can also use any models or data on collective servers that you have access to.
For example, here is the OAuth screen for . By logging in with Vana, you can bring your models and data to the application. If you prefer, you can authenticate using a crypto wallet (experimental). You choose the level of access to grant the application. You can grant access to only inference of your personal model, keeping the underlying data private, or you can grant full access to allow the app to have a copy of your data.
If you are a developer who would like to add support for Vana in your application, please see the for detailed steps.
