For everyone
The short version: a decentralized network of GPU operators serves AI inference, paid in LCAI, with every job anchored on chain. No central API, no platform middleman. This page explains it without jargon - the SDK docs cover the cryptography if you want it.
Live from the LightChain mainnet worker subgraph, refreshing every 30s
Five steps. Wallet to answer in 5-25 seconds on the public network.
You connect a wallet on LightChain. The gateway picks a worker from the public pool based on stake and recent reliability.
An ECDH key exchange wraps a fresh session key. Your prompt is encrypted with that key. Only the chosen worker can decrypt it.
The worker runs Ollama under the hood on its own GPU, locally on its machine. No cloud, no third party. The answer streams back encrypted.
Job ID, model ID, worker, and timing land on chain. Anyone can read who ran what. If the worker stalls, the protocol times them out and refunds the fee.
Your client decrypts the answer with its session key. Usual end-to-end latency is 5-25 seconds, depending on model + prompt size.
What the protocol gives you that a hosted API does not.
End-to-end encrypted between you and the worker. No log retention contract to read, no policy to trust - the worker physically cannot store what it cannot decrypt after the session ends.
Your wallet is your identity. No account to deactivate, no rate-limit table behind someone's API key. The protocol takes payment per call, in LCAI.
Anyone with a GPU can register a worker and earn LCAI for serving inference. No allow-list, no application form. That is what makes the supply side decentralized.
Heavy work runs on the worker. Only the receipts (who, when, which model) sit on the LightChain L1 - cheap to read, cheap to audit, never goes away.
What runs where, who built what, what to read for more.
The base layer. Sovereign L1, chain ID 9200. Hosts the worker registry, job registry, fee pool, and the LCAI token.
lightchain.aiBlock explorer for LightChain. Look up any job, worker, contract, or transaction.
mainnet.lightscan.appPublic dashboard of registered workers, stake, and recent jobs across mainnet + testnet.
workers-testnet.lightchain.aiThe official consumer chat. Same encrypted-inference pipeline LightNode SDKs use.
chat.lightchain.aiLCAI governance lives on both Ethereum (LCAIGovernor) and LightChain (LightChainGovernor + NativeVotes precompile).
dao.lightchain.aiCommunity SDK + UX layer. Encrypted inference in 5 lines, scaffolders for new apps, a one-click desktop worker app.
Open LightNodeRun one real encrypted inference in your browser. Connects to your wallet, signs two transactions, gets a streamed answer back. Use the testnet faucet so it is free.
Open the playgroundThe desktop app generates worker keys, funds them, stakes, and brings your node online. Earn LCAI for every job served. macOS, Windows, Linux.
Run a workerFive-line encrypted inference, Bridge + DAO SDKs, parallel batch + agent loops. One npm install, eight modules. Works in Node, browsers, edge runtimes.
