I need approximately 100 Bitcoin Testnet to run an experiment on the lightning network.

Any suggestion on how to run CPU mining? Should I use cgminer? Make any sense to perform solo mining on testnet?

Currently I am running a full testnet node with bitcoind on a linux environment.

  • Maybe you can find a faucet? Here is an older but probably still appropriate answer: bitcoin.stackexchange.com/questions/29791/…

    You will have to wait until the difficulty is reset to 1, and even then, you might not be able to win a block with the flood of other blocks coming in.

It's almost impossible to mine Testnet BTC with CPU, but there is a generatetoaddress command in Bitcoin Core:

bitcoin-cli generatetoaddress nblocks "address" ( maxtries )

If you want to continuously mine on Linux, create a bash loop:

while [ 1 ]
do
    bitcoin-cli generatetoaddress 1 "2N5fJkfCv4cF6vsa5QQJnsazBKWNXynn9zp" 10000000
done

  • 'generate' methods are only effective on Regtest, where you can create blocks at will. Testnet works like Mainnet (although with lower difficulty), so you need proper mining equipment to generate a block.

  • You can mine with this command, like I did, check my testnet BTC address: blockstream.info/testnet/address/… This is possible because the difficulty drops to 1 on testnet if there is no new block after 20 minutes.
