Private blockspace quickstart

Private blockspace encrypts your blob data before it’s posted to Celestia using a lightweight proxy.
In this quickstart, you’ll use hosted Celestia nodes (like QuickNode) instead of running your own.

Troubleshooting

Error message	Cause	Fix
TLS_CERTS_PATH required	Missing or commented-out cert vars	Generate certs (see above).
account not found	Unfunded signer	Use Mocha faucet.
blob: not found	Wrong commitment	Run blob.GetAll to find the real one.
grpc-status header missing	Invalid gRPC URL	Must be https://<host>:9090, no token.

✅ You’re done

You’re running private blockspace end-to-end using hosted infrastructure.

✅ No local Celestia node
✅ Fully containerized
✅ Encrypted data posted to Celestia
