Tests on blockchain configuration parameters

Question

We want to perform some tests with different values for the chain parameters (mining-diversity, target-block-time, maximum-block-size...), to compare the behaviour of the blockchain with different configurations. To achieve this, is it necessary to create several independent chains with different configuration on each? Or is it possible to change parameters in the same chain and recreate it?

Thanks in advance.

Regards.

Answer 1

A chain's parameters cannot be changed once it is running, since they are baked into the genesis block and locked down as a prerequisite to all other aspects of the consensus between the nodes.
