user127246: I come up with a protocol that can enhance the privacy of bitcoin. I want to do some simple experiments on the bitcoin blockchain. However, doing experiments on the real bitcoin blockchain seems expensive and unrealistic. Is there any way to simulate a bitcoin blockchain so that I can do an experiment on it?

user-1: You can use other chains:

Regtest
Testnet
Signet
