Hello and welcome!
4 blockchains most likely to host Truthcoin: Ethereum, Tendermint, Flyingfox, and NXT.
The team putting it onto ethereum is Augur http://augur.net/
(I used to work for them, and built their prototype)
Tendermint is a proof-of-stake fork of ethereum. I am currently living with the Tendermint team. Their plan is to use Augur. It is written in golang. Tendermint will be secure against up to 1/3rd of the validators attacking.
NXT is a blockchain that already supports trading to some extent, but doesn't have all the Truthcoin features yet. It is in Java. NXT uses a proof of stake algorithm that I don't know very well. I am not sure what percentage of the validators can be attacking. I don't know much about them.
Flyingfox is my project. The earlier versions were in python https://github.com/zack-bitcoin/augur-core
but now I am redoing it in elixir: https://github.com/zack-bitcoin/commerce/tree/master/flyingfox
Flying Fox proof of stake is secure against up to 1/2 of the validators attacking. Flying fox is not turing complete.
Flying fox is a little different from truthcoin. Instead of LMSR market maker with many participants, it uses tons of CFDs (contract for difference) to make bets between pairs of people. This way is more anonymous and scalable, because the bets don't ever have to be published onto the blockchain http://lightning.network/
Instead of Sztorc's consensus to determine outcomes of events, I will probably use a multi-sig. This is because of p+epsilon attacks. https://blog.ethereum.org/2015/01/28/p-epsilon-attack/
It is possible to be hired by augur or ethereum or tendermint, but I cannot afford to hire anyone for flying fox.
If you contributed ideas or code to flying fox then I will give you some of the coins when it launches.
