SuperNet is a collective of approved cryptocurrencies which will share a single architecture, and from what I understand, the capitalisation of SuperNet will comprise of a percentage of the approved cryptocurrencies within it, mitigating the risks if one of the coins doesn't succeed. Hopefully there'll be a mechanism to prune off such coins.
Who are the devs? And how many of them are involved?
James(jl777) is the core architect of superNET and has development support and assistance from crypto_zoidberg(Boolberry lead dev) and coinsolidation(Bitmark lead dev). As well as a team of 3 or 4 dedicated people working on the superNET GUI programming. And this will likely be expanded further as time goes on.
