How to delete the initial transaction/contract data except genesis block from dev network?

[frizzbuzz]

Hi, I set up a 4 node development network and everything works great. But I want to delete the default blocks except genesis and test with my own transaction data. Is there any way to delete the default blocks and contracts come with Dev network initialization ?

Firstly, BLocks in blockchain once created can't be deleted. As blockchain is immutable.

Secondly, the contract which is getting deployed at the time of setting up a development network is Network manager contract. This contract can not be removed from quorum maker at any point.

@frizzbuzz Once network is created using Quorum maker tool, it stores network metadata in few blocks .
As of now you can't reset quorum chain. Soon QM tool will be having reset functionality too.
