Chain-simulator

The chain simulator is exactly like mainnet blockchain, expect that there is no consensus and that you can generate blocks at will. It is the perfect setup for on-chain testing. MxOps gives some command lines to quickly setup the chain-simulator on your computer.

MxOps relies on this repository from the MultiversX core team to setup the chain-simulator itself, but also a gateway, an API, an explorer and an elastic search instance.

Requirements

You will need to have the following installed:

Start

Each time you start the chain-simulator, it is a completely new chain, all previous transactions you may have made in a previous session will be gone. To start the chain-simulator, just enter the command below:

mxops chain-simulator start

You will see all the docker containers slowly getting started, and the first epoch on the chain will be automatically pre-generated.

Note

If you forgot to stop the chain-simulator last time you shutdown your computer, you might get some difficulty to access the explorer. In this case, stop the explorer and start it again.

Stop

Once you are done, don’t forget to stop the chain-simulator:

mxops chain-simulator stop
