trueblocks-node

A minimal indexing/monitoring trueblocks node.

Installation

go install github.com/TrueBlocks/trueblocks-node/v4@latest

This will install the trueblocks-node binary in your GOBIN directory which is likely in your $PATH.

Testing

trueblocks-node --version

If this doesn't work, check your $PATH. No, we won't explain what this means. Google it.

Running

The easiest way to run this code is to copy env.example to .env in this folder and edit the values to match your system.

Then run:

trueblocks-node

If you'd rather not do that for whatever reason, try this...

Alternative

Export two values in the environment and then run the binary:

export TB_NODE_DATADIR=<your-datadir>
export TB_NODE_MAINNETRPC=<your-rpc-provider>
trueblocks-node

These two values are required (even if you're indexing other chains).

For TB_NODE_DATADIR, you may use special values for PWD, ~, and HOME which are replaced with the obvious values.

For TB_NODE_MAINNETRPC use the URL of valid (and fast) RPC provider such as those available from BlockJoy endpoints.

You may index other chains by exporting additional values in the environment. Please see the file called env.example in this folder for more information.

Other environment variables

You may increase the logging level of the node by setting the TB_LOGLEVEL environment variable. Valid values are debug, info, warn, or error. The default is info. debug is the most verbose.

Documentation

The documentation includes this README.md file.

Much more detailed documentation (which is derived from the source code), is available here.

Internally, trueblocks-node uses both the trueblocks-sdk and trueBlocks-core. In some cases, documentation for these packages may be useful.
