Re: [ANN][XCP] Counterparty - Pioneering Peer-to-Peer Finance - Official Thread
20 XCP bounty to build the ethereum smart contract logic for a powerball lottery on the blockchain using XCP
if someone can write the logic on the lottory using whatever is compatible with what Adam has ported to mimic the powerball lottery.
if you like this idea feel free to commit to matching my bounty amount or committing to give some XCP as well (or whatever crypto you want to use)
here is a sample lotto script
https://github.com/dennismckinnon/Ethereum-Contracts/blob/master/Dennys%20Lotto/Lottery.lsp
I know this is not a very detailed spec so please ask questions.

- include a section for the instantiator of the contract (lottery) to take a fee
it should be able to handle creating multiple "tickets"
it should distribute the winning based on how many numbers people get X of Y numbers (similar to how state lottos work)
it should allow people to trade tickets
it should allow users to redeem tickets
it should set limits for when tickets can be redeemed
if no one gets all the numbers the contract should roll over for another time period
the initiator should be able to choose how many number fields, time block period, and his pay out, and possibly the distribution logic (if you want to get fancy).
it should be open source on github
one of the XCP dev's need to look at it and say that the code is good (or a known, respected Ethereum dev)

Great initiative p! Can I add this on our bounty list https://forums.counterparty.io/discussion/807/list-of-open-counterparty-bounties#latest ?
yes
also i will pledge another 30 XCP if I get 50 XCP in pledges from a group or person
so far we have others pledging 10 XCP - Niceplum and tyhmakulho
what a strong, active dev and communication.
there might be one other thing that needs to be added to the smart contract and that is the % of tickets that win something. meaning that the awards adjust to pay out to the number of numbers someone's ticket gets so that the total number of tickets with payouts are at least 33% but not surpassing the next number threshold - meaning that if 4 of 6 numbers gets us 33% of all tickets, then 3 of 6 numbers gets 0.
we want some number of people to walk away from this and tell their friends that they won something (say 1/3), because that creates a viral effect so that their friends play.
or the other way to do this is that the contract keeps rolling dice until it reaches that magic number.
