Network entry

Access points

An access point is a public job API (gpn_scheduler). Hit one URL and the network routes your job to the best idle GPU — no provider addresses needed. They're permissionless and redundant: anyone can run one, so running several is the decentralized front door.

Testnet

Everything below is on the public testnet. Tokens have no monetary value, and the testnet can be reset or change without notice.

Known access points

The seeded entry is the current public entry point for the testnet.

Known GPN access points
Name	URL	Status	Notes
GPN Testnet (public)	`http://gpn-testnet.duckdns.org:8092`	Live	Current public entry point. LLM chat + job API. Testnet free-AI: the access point can pay escrow, so clients spend nothing. Health: `/health`; status: `/mode`; registry: `/providers`.

No other public access points are published yet. As the network grows, additional regional access points will be listed here.

Network nodes (bootnodes)

Three always-on, publicly-reachable full nodes run the testnet: one Linux bootnode and two Windows full nodes. New nodes dial these to join (P2P multiaddrs).

GPN full nodes / bootnodes

gpn-bootnode-1 (Linux)	`12D3KooWAFt…`	`/dns4/gpn-testnet.duckdns.org/tcp/30333/p2p/12D3KooWAFtUNxc6RgC9rq5uSHXd5XUncEcPqp77UU98oN6hSVFo`	Live

Check an access point

curl http://gpn-testnet.duckdns.org:8092/health
# {"providers":N,"status":"ok"}

curl http://gpn-testnet.duckdns.org:8092/mode
# testnet free-AI mode

curl http://gpn-testnet.duckdns.org:8092/providers
# live registry: gflops, latency_ms, models, active

Use one from your machine

See the Access the AI page for a working chat example and the full job API. Windows clients need no install — just PowerShell.

Non-loopback POSTs to an access point require Authorization: Bearer <GPN_AP_TOKEN> (or X-Api-Key). Tokens are set per access point and are never published here.

Run your own

Add an access point in one command

Point an access point at the chain and the providers you want it to route to. Expose the port, share the URL, and you're a new front door for the network — no special trust required.

Install & run

./install-accesspoint.sh
# install + start a systemd --user service:
GPN_INSTALL_SERVICE=1 ./install-accesspoint.sh

gpn-accesspoint-run

Env var	Meaning	Default
`GPN_LISTEN`	Listen address:port	`0.0.0.0:8092`
`GPN_ENDPOINT`	Chain RPC endpoint	`ws://127.0.0.1:9944`
`GPN_PROVIDERS`	Comma list of provider `/status` URLs to route to	`http://127.0.0.1:8093`
`GPN_SIGNER_URI`	Hot-wallet seed for testnet free-AI mode (creates + escrows jobs)	unset (mainnet = client-signed)
`GPN_AP_TOKEN`	Bearer token required for non-loopback POSTs	unset (set your own)

Config is written to ~/.gpn/accesspoint.env (chmod 600). Secrets stay there — never in a repo or on a webpage. Full details in the deploy guide and the run-a-node guide.
