# Kompromis-120b (K120b) - emission of the Eddycoin mainnet

Status: active. The spec SHA-256 is committed into the mainnet genesis (genesis.json, field emission.spec_sha256) and the formula is built into every node.

rate(t) ∝ [0.4157·0.25·e^(−0.25t) + 0.5843/120]·(1 − t/120)^2; integer: EPOCH 9,740 (108/yr), N 12,960, F0 15233476953, F_{k+1}=floor(F_k·1096969405493/2^40), C 712119615, s_k = even(floor((F_k+C)(2N−2k−1)^2/(4N^2))), final checkpoint 126,230,400 gets exact remainder 0.02696440 EDDY. Initial reward 159.44366220 EDDY = 79.72183110 per side.
