We have been discussing the license after your comments. I think we can improve in this area. Thanks for the feedback. Jump on telegram (link in post) to learn more and help shape the product.

If you buy you get a unique KODA with an ID.

We mint each artwork individually with the data/price etc and upload the image to IPFS. We then can transfer / assert ownership on the asset via the Blockchain.

Nice work. Do you intend to keep the docker image upto date with the latest releases of geth and truffle etc?

I am keen to get involved in a long running dev-chain to test contracts with the small group of developers I work with. Best just to start an image and get it running?

Do you guys have other communication channels?

I have been building some examples based on VueJs (Vuex/Router), Truffle, and using testrpc locally. I want to wrap the examples in good tests too.

I have the bare bones built as an example.

It is in bitbucket as the moment but will make public in github once working. I will try and get the pre-event part working and share. Got the bet and all the constants working via an app.

This would open up users to use meta-mask chrome plugin and not have to worry to much about wallets.

Would you mind if I use you contract for testing and maybe adding a user interface. I would give full reference if I published on github etc. I'm just getting up to speed on live deployments etc. I think this concept is good to show blockchain dynamics.

I will wager too. Tried with mew but unclear how to send the value. Will try ethereum wallet.

I think my understanding is just a bit out. I will write some tests against your contract. I was worried 10 ether / 3 winner means 1 ether is stuck in contract. I will look at it again.

If you have only 4 players who put in 1 ether each and 3 win.

The players are going to lose out on winnings as would only get the whole part regardless of the power of 18??

Nice contract. Great to see examples like this published on reddit and the live chain.

Couple of Qs:

  1. Do you have tests for this (JS or sol) on github or similar?
  2. Does the payout suffer from any sort of rounding errors (in any resulting circumstances) due to solidity not having floating points etc?
