I am currently building proofcore.com up to something similar to the Waves platform, but using Multichain to build it, where different tokens can be issued and traded decentralized through android or desktop wallets. Currently all Tagcash Wallet transactions in PHP are on our PCM blockchain (ProofCore Money) and we are in process of converting client points wallets into Tokens as well.

There is a native cryptocurrency built into the platform, called PCM (ProofCore Coins for want of a better name)

I will be integrating TagCoin into the PCM chain in 2 ways. There will be a 1 to 1 conversion from TAG to PCM, or we can burn TAG to add TAG tokens on the chain...we will be offering this to other coins, especially coins with no dev support.

I may look at doing an ICO (aka Token sale) for PCM  in a few months, but untill then the equivalent of a presale will be done just for TagCoin holders and miners. There is a total of 100 million PCM tokens issued, with permissioned round robin validation (mining) done to earn from transaction income.

Moving forward, we will probably keep accepting TagCoin into Proofcore on a 1 to 1 basis, since there is no traditional mining or PoS in Proofcore. This should keep the value of TAG the same as PCM. It is a lot easier to develop apps on Multichain, since it used Bitcoin Core Protocol, along with all the libraries out there for Bitcoin.

You can see more on ProofCore.com, with details of the other chains we are building, all of which will be using PCM to transact. I will be setting up a new discussion area in in BitcoinTalk for ProofCore soon.
