Regtest

1 min read

The Regression Test Network (regtest) is a parallel blockchain to the Bitcoin blockchain. It works almost identically to the Bitcoin network, but it is used for private development. Regtest is most similar to testnet in that the coins on the regtest network are not monetized. Additionally, regtest is meant solely for private testing; external connections are not enabled and the mining difficulty is set to zero. This allows a regtest user to mine as many blocks as they want, making testing easier.

Mining
Mining is the process of building the blockchain by adding new blocks one at a time. Most of mining involves finding a valid Proof-of-Work, which is an energy-intensive guessing game.
