1  Bitcoin / Development & Technical Discussion / P2SH-P2WPKH (Segwit) change addresses in Bitcoin Core - how? on: August 21, 2017, 11:15:13 AM

I am running a service that accepts user deposits and sends withdrawals. I am using Bitcoin Core for the wallet.

I'd like to go full-Segwit with my service, but here's the problem: bitcoind wallet does not generate P2SH-P2WPKH (Segwit) change addresses by default. So even if I generate P2SH-P2WPKH addresses to accept deposits from my users via addwitnessaddress, whenever I send coins, the change is going to a P2PKH address.

I could manually create a P2SH-P2WPKH change address by (in pseudocode):

tx = createrawtransaction([], amounts)
chaddr = getrawchangeaddress()
chaddr = addwitnessaddress(chaddr) # this creates a P2SH-P2WPKH address from the P2PKH change address
# now fund the transaction
tx = fundrawtransaction(tx, changeAddress: chaddr)['hex']
tx = signrawtransaction(tx)['hex']

No the thing is that addwitnessaddress(chaddr) breaks things a little since the resulting address is added to account addresses, and is NOT marked as a change address. Therefore it is used as a regular account address and generates send/receive transactions. It looks like it does not break anything except creating additional transactions returned by listtransactions and inaccurate "amount" fields.

So, a solution I'd really love to see is:

1. make the wallet generate segwit change addresses by itself so that we can just use sendtoaddress and other RPC calls without workarounds (maybe an option in config?),
2. somehow make the address resulting from addwitnessaddress(chaddr) as a change address,
3. or allow getrawchangeaddress to generate P2SH-P2WPH address in the first place.

Obviously (1) would be much better, but at this point I am looking for any solution that would "just work" and not break my workflow.

Cheers and thanks,
2  Economy / Service Discussion / Advertizing a gambling/dice game - need opinions, thanks! on: January 25, 2017, 11:36:25 AM

I would like to hear your opinion (or about your experience in) advertizing a gambling site. I have created and am running, yet another gambling site. Now the thing is it's doing pretty well, but is quite young (little over 1 month). It already has investors, players and I am sure it's on the right way to become a big one, but I would like to speed the process a bit with advertizing.

We are already doing:
* sig campaign on BitcoinTalk
* in-site referral program
* started Twitter giveaways and planning a few more

But I am looking at other options and was thinking about checking advertizing - CPM or CPC. Since I have never advertized a gambling site, I can see there are already a few Bitcoin-centric advertizing networks, I would really like to hear some opinions if you decide to share!

Thanks and cheers,

Why did you create YOLOdice?

When Just-Dice closed in 2014 we were so addicted to this kind of entertainment that we felt something had to be done. Our goal was to give people (and ourselves) a similar level of adrenaline, a sense of community and a chance to play with their favorite crypto currency. We knew it would be difficult, given the number (and quality of some) of existing Bitcoin games, but hey, why not?

At the time we were stuck coding a multi-coin pool, but decided to pivot. It took a while because we've been working on other projects meanwhile. YOLOdice ended up as a pretty demanding project too.

What's your goal?

Believe it or not, we want YOLOdice to be a fun place to chat, play and spend time. We want to provide an exciting game for these who want to play using their favorite crypto. It wouldn't be fair if we said we do not care about our profits at all, but we never put money first. It's the cool stuff we do that drives us. We definitely want to establish a trusted site with long-term relationships with investors and players.

Who are you?

We are 2 developers currently living in (coldish) Europe. We have been closely working together for about 10 years now, one of our project is a pretty popular web publishing platform. I am close to 40 years old, have a wife, a few kids and have always liked challenging projects. I was a computer geek since I was 7 years old (ZX81, ZX Spectrum if anyone remembers?) and witnessed the computer and Internet revolution first-person. Now I am hoping to witness and be a part of economy changes (in which Bitcoin could play its role).
