It is awesome to see more Steemit tailored and Steemit exclusive content from you, @davidhay! Great overview of Wanchain and Wancoin, thanks! The cross-chain transactions would be huge but also seem to be a tricky one to pull off. I'll definitely add Wanchain/Wancoin to my watch list. You didn't mention the total supply of Wancoin. According to the current implementation of the ERC-20 token, it is 210'000'000 WAN (etherscan.io). I guess this will also be the total supply once they run it on Wanchain and not Ethereum anymore.
