Title: Bitcoin Testnet/Faucet?
Post by: revolvingcash on August 18, 2019, 06:48:55 AM
Hey guys, I'm trying to get 2 bitcoin to do some experiments. Is there any faucets that pays big? Most of them are just paying like 0.001 which takes forever. It's energy consuming :( If anyone could give me 2 btc, that would be great support for me

I've PM'ed this user (https://bitcointalk.org/index.php?action=profile;u=1925846) which apparently has a lot of coins. He has sent many tBTC's at once to many users who were in need.

What kind of experiments do you want to perform? Some of them might be suitable for the regtest mode built-in Bitcoin Core. Here (https://bisq.network/blog/how-to-set-up-bitcoin-regtest/) you can find a guide on how to enable and use it.

Here is a quote of my post, where I gave a testnet private key with balance of 1BTC.
The coin is still there for anyone to take :)

Here is an address with 1BTC in it. and its private key. Have fun

Bitcoin Address:

Private Key:
cT2z7HL8j3HoSBEHuoCBggn6R12AXBqSiQhKVeA8bh5yQvyiQf7k

It can be moved by eg. installing some testnet wallet in your (android) phone.

What art you trying to do / why do you need 2BTC of testnet that you can't do with .2 or .02 or .002?

I wonder about it as well. I only could think potential error such as Overflow/Underflow error if OP use static programming language

but couldn't it be tested even without "actual" test cases?
something like overflow belongs to lower level functions and in all programming languages that i know there is always easy ways to test them. for instance in object oriented programming we use Mocks to test any special case we want easily!

Yes, but in reality it often happens even on Bitcoin (somewhere in 2010) and big company such as Boeing 787 (http://www.engadget.com/2015/05/01/boeing-787-dreamliner-software-bug/).
And the worst part, it creates domino effect.

I'm not software engineer, so i might be wrong though and we can't know OP's reason needs lots of tBTC for sure.

Boeing is kind of a bad example in that case though. Their whole Boeing 737 Max mess killed hundreds of people and was mostly caused by questionable management decisions -- ie. having pilots rely on warning lights that weren't enabled by default [1], horrendly cheap outsourcing to developers that completely lacked the expertise [2], all of which lead to software errors that could have been easily avoided.

That being said, while manual testing is also important for creating stable software, I agree with pooya87 that in this case testing could be easily done using mocks. At least I personally can't think of any edge cases where using 2 tBTC would make any difference to using 0.002 tBTC.

And since he never came back we can never know.
The only edge case I could come up with is that he wanted to test making 1000's and 1000's of small transactions to do something and that yes, you can do the same with less. However, since they are not mining their own transactions even 1sat + fee .005 can be eaten up somewhat quickly.
But, that is a very edge case.

Seriously, in less then 1 day after seeing this post I got myself .1 testnet coins using the faucets.
I did not try that hard and then I got bored so if he really wanted to it's not that much work.

Yes, I donated the coins back to the faucets.
