Custom chain

This example demonstrates how to start a short-lived Fuel node with custom consensus parameters for the underlying chain.

First, we have to import ConsensusParameters and ChainConfig:

{{#include ../../../examples/cookbook/src/lib.rs:custom_chain_import}}

Next, we can define some values for the consensus parameters:

{{#include ../../../examples/cookbook/src/lib.rs:custom_chain_consensus}}

Before we can start a node, we probably also want to define some genesis coins and assign them to an address:

{{#include ../../../examples/cookbook/src/lib.rs:custom_chain_coins}}

Finally, we call setup_test_provider(), which starts a node with the given configurations and returns a provider attached to that node:

{{#include ../../../examples/cookbook/src/lib.rs:custom_chain_provider}}
