Running a Node

TODO: Improve documentation of gaiad

Basics

To start a node:

$ gaiad start <flags>

Options for running the gaiad binary are effectively the same as for tendermint. See gaiad --help and the guide to using Tendermint for more details.

Debugging

Optionally, you can run gaiad with --trace-store to trace all store operations to a specified file.

$ gaiad start <flags> --trace-store=/path/to/trace.out

Key/value pairs will be base64 encoded. Additionally, the block number and any correlated transaction hash will be included as metadata.

e.g.

...
{"operation":"write","key":"ATW6Bu997eeuUeRBwv1EPGvXRfPR","value":"BggEEBYgFg==","metadata":{"blockHeight":12,"txHash":"5AAC197EC45E6C5DE0798C4A4E2F54BBB695CA9E"}}
{"operation":"write","key":"AjW6Bu997eeuUeRBwv1EPGvXRfPRCgAAAAAAAAA=","value":"AQE=","metadata":{"blockHeight":12,"txHash":"5AAC197EC45E6C5DE0798C4A4E2F54BBB695CA9E"}}
{"operation":"read","key":"ATW6Bu997eeuUeRBwv1EPGvXRfPR","value":"BggEEBYgFg==","metadata":{"blockHeight":13}}
{"operation":"read","key":"AjW6Bu997eeuUeRBwv1EPGvXRfPRCwAAAAAAAAA=","value":"","metadata":{"blockHeight":13}}
...

You can then query for the various traced operations using a tool like jq.

$ jq -s '.[] | select((.key=="ATW6Bu997eeuUeRBwv1EPGvXRfPR") and .metadata.blockHeight==14)' /path/to/trace.out
