Block 333500 passed. Bring on the multisig and free asset issuance features in Counterwallet!

Multisig and Free asset names now live in Counterwallet! Wink

Great! And they're off to a flying start - https://www.blockscan.com/asset!

no squatting huh Adam? Tongue

Now every counterpartyd instance has to use computing power to process this spam

If I was an evil miner and didn't like counterparty I would stuff the transaction block with as many of these as possible to impact the performance of xcp software

It has, and always will be, possible to use Counterparty to create useless transactions (as with Bitcoin). The computing power required to process them is as near to zero as you can get, and certainly not a cost-effective way of impacting performance.

not tech savvy enough to understand if it would be possible to implement it in counterparty? I think the niche here is great especially for btc altcoin trades

Happy mother of 5 children

Here's a list of all XCP assets.
http://xcp.pw/allassets.html

More than 500 assets have a URL in their description. Quite a few land on a broken or empty page, but there are also a lot of "hidden gems".

I clicked through some of the links. The most interesting and creative projects I discovered:
http://docs.xcp.pw/ - http://coindocket.com (Bitcoin Consumer Protection)
http://dohod.xcp.pw    - http://dohod-s-nulya.ru/ (blog on business ideas - in Russian)
http://edeniancredit.xcp.pw - http://kingdomofedenia.webs.com/ (a micro-nation - unfortunatly disolved)
http://exodus.xcp.pw - http://exo.me/ (a design company)
http://teur.xcp.pw - More info: transparenteuros.tumblr.com (Transparent Euros)
http://bitlance.xcp.pw - bitlance.biz shares (freelance network)

Thank you for the thorough review! I'll take a look at addressing the issues when I get the chance. (Might be a day or so.)

Update: I've made some quick fixes for the two issues identified as blockers. I've added test cases for both, and they're both pushed to the repo:

https://github.com/PeterBorah/ethereum-powerball

That might be enough to fulfill the conditions of the bounty. However, as a matter of professional pride, I want to spend a little more time working on the quality of the code. The sorts of bugs found reveal what the weak spots are, and I have some ideas for making it more robust.* So, I'm going to try to work on that over the next couple evenings.

* For the programmers in the audience: I've basically got an implicit state machine with some pretty complex effects. I want to model it more directly so that it's easier to reason about and harder to end up in weird partial states. I'm also not dealing with storing data in a very principled way, so I want to think about encapsulating some of that.

Can you reply to this post with your XCP/BTC address.

Then I will send the link to the people who pledged to support your coding of this smart contract.

Me - 50 XCP
Matt Y - 20 XCP
Ivana - 10 XCP
Niceplum - 10 XCP
Tyhmakulho - 10 XCP
Ian - 10 XCP
Dante - not sure, expressed interest
Tusk - 2 XCP
Jonathan O - 3 XCP

Grand total: 115 XCP or about $600 equivalent at today's rates.

I am going to ask them all to send it directly to you as I don't want to be the middleman. Anyone sending please post here to confirm (if you have a bitcointalk account, some people may not).

Also, as I didn't explicit a reward for the code review, if you would not mind perhaps sharing a % of it to the person who did the code review. https://gist.github.com/jorisbontje/353f69515a16cef7de7b I will ask him to put his XCP/BTC address in the git repo.

I have not had time yet to get this running on the testnet to try it out but will spend some time this week to learn how to do that (haven't run counterpartyd since Feb so that will be interesting...), and then am also asking some people around who know people in the gaming space to see if we could perhaps demo this capability for them and get them interested in using XCP and Ethereum for their business.

Thanks! Cheesy

10 XCP on its way from Ivana http://www.blockscan.com/txInfo/11540071

I was definitely planning to pass some of the bounty to the code reviewer. As I said, it was a very good and thorough review. Does 20% seem fair to everyone?

Let me know if you have any other smart contract work you need done. Wink

And I'm still planning on trying out some code improvements over the next few days. I'll be happy to help debug if you run into any issues with your testing.

cool I put in the withdraw request of 50 xcp on poloniex to your address, i think they are installing a new server network card so it might take a few hours. I will post the tx ID when I see it.

I also sent an IM to all the others for the remaining amounts and will follow up.

Hi

Is anyone else having problems with Rock Paper Scissors?

As my game history shows, I appear to win because my opponent often makes move "NA".

Please could someone explain why the game does not appear to work effectively? Are players too impatient to wait for conformations?

The problem is that the other user isn't finishing the game. There's no way to tell why not.

Thanks for your reply. Do you often play the game? I keep trying but the other user never does anything. This makes the game unplayable. Cant the rules be changed so that players must reveal within say 2 blocks?

yes the prize amounts cannot be the same as powerball since it is unrealistic to use fixed pay outs unless this is being done by a large entity who already has the funds. the payout as i mentioned above should ensure that at least 33% of the tickets get something. does it do that?

You're going to need a big bankroll regardless, if you want to run any sort of lottery. That's because, by definition, if you're working with fixed probabilities there's no guarantee reality will follow exactly the expected distribution. What if only one person enters, and they win a prize? (The situation is different with a raffle, where the probabilities and payouts change together.) Real lotteries solve this problem by buying insurance and things like that.

I originally followed the probabilities of the real Powerball for payouts, which means that you have about a 1/35 chance of winning a prize. I just pushed a change giving the ability to payout on fewer matched numbers, so that you can bring that number down if you like. If you give a small payout for even a single match, my back of the envelope calculations say people should have about a 50% chance of winning.

cool thanks!

Hopefully one of the dev's can check your code soon, so you can get the award. I'll keep bugging them but I guess it is the weekend.

No worries! Thanks for setting this all up!

I should say, if there's anything you don't like about the way I interpreted the spec, let me know. I'm happy to make any tweaks that are necessary. I want everyone on both sides to feel good about how this went.

ok thanks

i am going to sleep now, it took me way longer than i thought to drive on a1a from miami beach.

i'll bug people tomorrow about checking the code

worst case i will try to see how to run it myself on the test net - i guess i might as well try since this (ethereum contracts) is a major new feature of XCP

so here is the review of you code, there are a couple issues that need to get resolved.

https://gist.github.com/jorisbontje/353f69515a16cef7de7b

a snippet from the conclusion:

Code:

Then intend of the code is good, but in the implementation I have identified a couple flaws:

As stated under 6, the redemption deadline isn't fully implemented. This is problematic as it conflicts with the administrator being able to withdraw funds after the deadline.
Winning numbers can be redrawn multiple times after the lottery deadline, potentially overriding previous drawings. https://github.com/PeterBorah/ethereum-powerball/blob/master/contracts/lotto.se#L62-L81 As this can be triggered by anyone this is a serious concern. Suggested is to 'freeze' the lottery after the lottery deadline until the redemption deadline has expired as well.
Relying on block.prevhash is a security risk as this can be abused by miners / mining pools using a block withholding attack. If this is a real threat depends on the payout amount of the lotto. Since the RNG is configurable, I'd consider this to be currently good enough for the bounty.
Minor feedback for improvement:

use def init for automatic initialization upon contract creation
specify explicitly in requirements.txt which pyethereum / ethereum-serpent library are supported
create user interface ;)

Can Counterparty adopt something like this - http://blog.coinprism.com/2014/09/10/proof-of-authenticity-of-cryptoassets/ - to verify the issuers of legit assets?

I brought this up on github, and one of the core devs already said they'll add it. It's not a big deal.
