Some of the SoG cards are already playable in EverdreamSoft´s previous trading cards game, Moonga. More cards are being integrated as time goes on. This is a way to explore how blockchain based game assets can be used on multiple game platforms and also get the previous user base of Moonga players involved in using blockchain based digital assets and to hopefully onboard some of them to Spells of Genesis. Find out more about Moonga at
http://www.moonga.com/ All the SoG blockchain based digital game assets can be freely traded outside the game and also, other game devs can choose to integrate these into their own games if they want. The
www.FreeMyVunk.com movement is promoting this concept of digital game asset sharing between different games. I think SoG is also part of this reVUNKolution in a way even though their game assets are issued on Counterparty and not the Ethereum platform used by FreeMyVunk.
Great info thanks.
I wonder if SoG assets and the vunk asset system can somehow work together in the future... seems ETH has lots of momentum and Counterparty not so much.....
As I mentioned, the FreeMyVunk people are already in contact with SoG to hopefully work on ways to make this collaboration happen. Also you may be interested in the following article:
http://counterparty.io/news/counterparty-recreates-ethereums-smart-contract-platform-on-bitcoin/In the article we find this paragraph: "With Counterparty Contracts, users may write Turing Complete smart contracts into the Bitcoin blockchain and execute their code on all Counterparty nodes. We’ve ported Ethereum’s language and virtual machine over to the Counterparty platform, using the pyethereum codebase. The result is hosted on GitHub and open for public testing. Today, you can take Turing Complete Ethereum code, or write your own, and run it on Bitcoin with Counterparty. Anything that one could ever do with Ethereum, one can now do with Bitcoin and Counterparty..."
So as you can see, the groundwork has already been laid for cross-pollination between the two platforms.
On the other hand, I disagree with your statement about counterparty not having a lot of momentum. Granted, there is a lot of hype around the ethereum platform (though it is not even really finished or proven to be secure yet) while counterparty tends to work quietly in the background, didn´t do a multi-million dollar crowdsale or concentrate much on PR. However, besides SoG, I´d like to mention the following highly promissing counterparty projects:
1) Storj decentralized client-side encrypted cloud storage network
http://storj.io/ and
http://driveshare.org/dataserv.html - already in its second round of beta testing with around 1000 farmers contributing 3 Pb of storage, and about to start the third round of testing shortly.
2)
http://getgems.org/ encrypted messaging app that rewards its users for using the app with GEMZ token airdrops which in turn can be used to purchase gift cards from Starbucks, iTunes, Amazon and others or be traded on altcoin exchanges like poloniex.com.
3)
http://foldingcoin.net/ FoldingCoin is a registered non-for-profit that that distributes tokens called FLDC to reward participants of the global Folding@home network (a Stanford University project) which lets people contribute their unused CPU and GPU power to help find cures to diseases like Alzheimer, Parkinson etc.
4)
http://scotcoin.org/ The Scotcoin Project was created with the intent to serve as the Scottish citizens´ money supply to be the first official decentralized currency of a country. Scotcoin has recently been in the news for being accepted to buy beer in a Glasgow pub, and is actively traded on the Bittrex altcoin exchange.
Counterparty is currently running its DEVPARTY contest to attract new applications, where 15 innovative projects are competing to win 9500 XCP in prizes.
, but typically successful CEOs have big plans to rule the world, so I am banking on this team right now.
