Get 5 free bitcoins from freebitcoins.appspot.com
June 11, 2010, 05:38:45 PM
For my first Bitcoin coding project, I decided to do something that
sounds really dumb: I created a web site that gives away Bitcoins. It
is at: https://freebitcoins.appspot.com/
Five e3f per customer, first come first served, I've stocked it with
e3f1,100 to start. I'll add more once I'm sure it is working
properly.
Why? Because I want the Bitcoin project to succeed, and I think it
is more likely to be a success if people can get a handful of coins to
try it out. It can be frustrating to wait until your node generates
some coins (and that will get more frustrating in the future), and
buying Bitcoins is still a little bit clunky.
Please try it out and get some free coins, even if you already have
more Bitcoins than you know what to do with. You can get some and then
donate them right back; the address
is: 15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC

I really like that. Do you think it would be good to post when the
number of bitcoins left is below 200-300? That way people like me could
donate to it to help keep this going.

Couldn't someone just keep making new bitcoin addresses and drain
your system?
You should at least toss recaptcha on there.
It only gives 5 coins / IP / day. I dunno if it also checks
addresses.
But it's true, a good captcha wouldn't be a bad idea.

Yeah, using only the IP is somewhat unsecure, but it's better than
nothing.
I wonder if it's possible to generate coins on app engine...

Showing the number of Bitcoins available is on my TODO list. I just
checked and the balance is up to 1,135 (thanks to whoever donated!).
And right now it is 5 bitcoins per IP address (not bitcoin address).
Not per-day– just 5. I want to start out conservatively, I will loosen
it to 5 per (day?/week?/month?) if people start having lots of trouble
because they get a dynamic IP address from their ISP that already got
some.
RE: captchas: yeah, I was gonna start out with a captcha, but I
wanted it to be as simple and non-threatening as possible. I
don't think anybody who has access to hundreds or thousands of
working public IP addresses would go to the effort of writing a
bitcoin-harvesting robot, though I suppose somebody with a botnet might
take a crack at it. To make that tougher I could make it 5 bitcoins per
IP AND 5 bitcoins per bitcoin address (so they couldn't have all the
bots in the botnet using the same BC address).

I got 5 then felt bad so sent you 50 back

My mistake. I don't see that being a big problem. Perhaps have it
reset every week? I doubt you'll be hard-pressed for coins, at least for
now.
To make that tougher I could make it 5 bitcoins per IP AND 5 bitcoins
per bitcoin address (so they couldn't have all the bots in the botnet
using the same BC address).
That actually wouldn't help much. It's completely trivial to generate
a new address per transaction (with JSON-RPC). If I were coding a
botnet, that's how I'd do it. Adding a CAPTCHA might be wise if you
notice problems, but for now I doubt you have much to lose by skipping
it.
Just out of curiosity, how did you build that on the App Engine?
Could I possibly see your source? I might set something similar up on my
local server. As I understood it, you can't make any sort of outbound
request from app engine, though. So how do you send the coins?

I'd be happy to share the interesting bits, but the architecture is...
um, unique. I'll start a thread on the Development forum describing how
I built it.

I've been able to drawn 50 BTC in minutes using Tor. Please add some
address filter too, so the same address can't be used twice. I'll also
provide a Tor blacklist if you'd like.
PS: I've paid back those BTCs.
It's out job to disarm thieves so this currency won't be subjected to
the same atrocities as in real world.
This currency shall not be used for one to be rich and in control and
others poor and under control.

He's giving it away, it's an honor system, so don't take more than
you need

Of course. I didn't. But that doesn't mean others won't too.

How many public Tor exit nodes are there these days? You've
essentially blacklisted 10 of them already
I am going to add a one-donation-per-bitcoin address rule to make it
a teeny-tiny bit harder to cheat. I don't want to blacklist anybody
coming from Tor, though– I think a lot of people using Tor will also be
interested in Bitcoin.
I'll implement a CAPTCHA when (if?) the current service starts
running low on coins (there are 1,570 bitcoins in the faucet right
now!).

About 1500-1700 exit nodes on Tor. Yea, people using Bitcoin might use
Tor, but not for your service. My suggestion is to ban open proxies.

Gavinandersen, you gave me 13.37 (leet) BTC?

Gavin, you should set DEBUG = False in your Django settings next
time. I hit some kind of exception page and it gave me your secret and
the URI of your JSON gateway.
I'll send your bitcoins back to you if you'd like. I'm emailing you.

Thanks, lachesis– ฿50 to you for finding that bug!
I've changed the key and turned off debugging; I'll tighten up its
security a little more tomorrow when I'm more awake.
And wobber: no, I didn't send you leet ฿

The Bitcoin Faucet now shows how many coins it has available to give
out (on the left-hand side of the page). The number is only moderately
accurate– donations will take 5 or 10 minutes to show up in the
balance.
I also implemented another anti-cheating measure that should make
casual cheating a little harder (which I don't want to say too much
about because that would make it easy for cheaters to know what to
do).
I'm very pleasantly surprised at how well freebitcoins is working so
far; thanks again to everybody who tried it out and who donated bitcoins
to it!

Excellent choice of a first project, nice work. I had planned to do
this exact thing if someone else didn't do it, so when it gets too hard
for mortals to generate 50BTC, new users could get some coins to play
with right away. Donations should be able to keep it filled. The
display showing the balance in the dispenser encourages people to top it
up.
You should put a donation bitcoin address on the page for those who
want to add funds to it, which ideally should update to a new address
whenever it receives something.
