Open-source blockchain where AI models run on-chain inside smart contracts
An EVM-compatible execution environment that adds on-chain AI inference, using the GPU instead of the CPU to run nontrivial machine learning models.
Produces identical AI inference results across heterogeneous computing hardware, which is what allows AI to be executed on-chain without an off-chain oracle.
Quantization and integer-only inference techniques that make model execution efficient and reproducible inside a blockchain environment.
A zkRollup solution that aggregates side-chain transitions into a single main-chain transaction, raising TPS and lowering per-transaction fees.

Open data infrastructure where people own and authorize the data behind AI
People collect data from services they already use through open-source connectors, and that data stays on their own device or encrypted storage they control.
A locally running access engine encrypts data and releases it only against a valid on-chain permission, with every read written to a reviewable access log.
Install @opendatalabs/vana-sdk to request user-approved data, read it from a Personal Server, and settle protocol fees from an app escrow balance.
Groups pool data for privacy-preserving compute jobs, so contributions can be used by AI without exposing raw records.
