Migrate to regtest

[vnprc]

Currently, Hashpool mines to testnet4. There are two issues with testnet4:

1. New installs have to sync up the blockchain before minting any ehash tokens. Testnet4 is a relatively new blockchain so this only takes a few minutes but it adds friction to spinning up the dev environment and the sync time will continue to increase in time as the blockchain grows longer.
2. In order to test ehash redemptions we will need the ability to mine blocks. We need to get off of a proof of work blockchain in order to mine blocks on demand.

imho, regtest is suitable for unit/integration testing/CI/CD type of workflow.
Currently we're using testnet4?

Another option is mutinynet, which has 30sec block times.

Yes, currently Hashpool points at testnet4. There are two issues with testnet4:

1. New installs have to sync up the blockchain before minting any ehash tokens. Testnet4 is a relatively new blockchain so this only takes a few minutes but it adds friction to spinning up the dev environment and the sync time will continue to grow.
2. In order to test ehash redemptions we will need the ability to mine blocks. We need to get off of a proof of work blockchain in order to mine blocks on demand.

I will add these points to the top level description for this issue.

I understand and agree.

For dev/test - regtest
For alpha deploy - testnet4
Beta deploy would likely be mainnet.

Thoughts?

Thanks for jumping on this one @machuPikacchuBTC! This might be a super easy ticket, now that I'm thinking about how to accomplish it. I'll have to line up the next task for a quick followup. =D

Two things are needed to close this issue:

• update the network flag in bitcoin.conf
  • we should also move this file into the new config directory
• add a new just recipe to mine a block
