Open your mind :P, Steem is open source and you can use the code for new blockchains projects. Thousands of new projects are derived from the Bitcoin code. Steem uses the Graphene code that is from Bitshare. CREA and Creary.net are in beta test, for this reason it is assumed that there are only two test nodes.

CREA Network has modified many of the parameters of Graphene and Steem. CREA uses 25 nodes in the DPOS protocol (Steem 21), 8 weeks to transform the rewards to the liquid token CREA (Steem is 13 weeks). The contents can be voted for 10 days (Steem 7 days in Steem) and other different features..
