In anticipation of their upcoming “Real Time Authorizations (RTA)” Supernode Mining launch, Graft Blockchain has released some details regarding the mining release and stimulus plan. The company has stated that the primary goal of the supernode mining release and stimulus plan is to develop the network to a robust state prior to the launch of “Point-of-sale transaction support on their mainnet.”

For a start, Graft is gunning for active SuperNodes in the range of 250 to 1,000. This is their metric for measuring a healthy supernode network. They expressed concerns in a network with very few or significantly high supernode operators. Too few, and the integrity of the network can be compromised, and too many could mean lesser returns for investors.

Talking about investors, Graft has estimated the monthly ROI to be between 4-5%. The initial stimulus package is expected to be 2,500,000 GRFT per month, with possible SuperNode participation of up to 500 operators.

There are 4 Supernode tiers on the network, each with varying collateral and profits. Each tier receives ¼ of the fees for associated transactions. The collateral for Tier 1, 2, 3 and 4 are 50,000 GRAFT, 90,000 GRAFT, 150,000 GRAFT and 250,000 GRAFT, respectively. Two supernodes are randomly selected from each tier for every transaction (making a total of 8 supernodes).

GRAFT payment processing network functions similarly to a credit card processing network with off-chain authorizations and in-network atomic swap based interchanges.
