How do I generate coins on testnet? CPU, GPU, FPGA? Are there pools?

Is it possible to mine coins on testnet using CPU? GPU? How about FPGAs?

Are there any pools running on testnet?

The reason I am looking for this is so I can master the new API's relating to AddMultiSigAddress

Get free testnet coins here: http://tpfaucet.appspot.com/ or http://testnet.mojocoin.com/

If testnet coins are this difficult to get, what's the chance people start throwing in some real money to speed along the process?Kinnard Hockenhull 2012-12-14T03:01:22.117

@KinnardHockenhull From what I've read, testnet coins are easy to come by, and people have extras and historically just freely traded them. I don't think they are difficult to get per-se, I just don't know how to get started.goodguys_activate 2012-12-14T03:14:58.150

Testnet is designed to test Bitcoin software - including parts that have to do with finding blocks. As such, it should be easy for developers to generate testnet coins.

Because of this, it will be easy to solo mine on a CPU to generate them, and you should not use anything heavier than that because you would ruin it for everyone else.

It is also not designed to test pools, by the way. If you need a pool for whatever you're doing you can do that (but don't bring too much hashpower to it), but if it's the pool itself you're testing, do it on the main net.

Understood... I will only CPU mine on testnet. To do this, all I need to do is edit my local bit coin.conf to gen=1 for coins?goodguys_activate 2012-12-14T04:50:24.927

@makerofthings7: I think so. I haven't used testnet myself, or seriously tried to CPU mine.Meni Rosenfeld 2012-12-14T04:51:55.770

I'll launch it now on OSX and see what happens in the morning. I'll post the results as well...goodguys_activate 2012-12-14T04:52:33.290

@makerofthings7 How'd it work out?Kinnard Hockenhull 2012-12-17T07:38:09.410

1@KinnardHockenhull I have gen=1 on a fast Macbook Retina running for the past 48 hours... nothing. 8 CPUs. I may have to use my FPGA or weak Nvida card. Any recommendations? on software?goodguys_activate 2012-12-17T11:33:19.550

Unfortunately, this answer is no longer true. The testnet difficulty is currently around 4 million, and a typical CPU would take many months to mine a block.Nate Eldredge 2019-02-25T03:38:56.877

If anyone need a few testnet coins, drop me an e-mail at jim@bitlc.net with an address and we'll work it out. I have a "few" as a result of poolserver-software development and testing.

I could also use few testnet coins - the address is mgQCSPNP6vsdQBYmnx9hk7AZXpUA6tck6j. Thanks in advance!Kozuch 2013-11-17T18:35:22.903

Can anyone spare some test coins to me: mv3kpEMEuBqN2brSAPGyzBU8VMrY5epr7Djan 2014-01-14T16:46:30.207
