Gold spot (XAU/USD), month-end close. The SOST line is the gold line × the fixed reference weight (1.14 mg) — it moves only with gold, never by decree. Gold reference, not a market price; once SOST is listed, its price evolves on its own, no longer tied to gold.
SOST uses a smooth exponential decay emission model, not a sharp halving like Bitcoin. Each epoch, the block reward decreases by a factor of q = e-1/4 โ 0.7788, which means a ~22.12% reduction per epoch โ a gradual, continuous curve instead of abrupt 50% drops.
The Mathematical Constants
โข Decay factor q = e-1/4 โ the natural exponential base raised to -1/4. This produces the smoothest possible decay curve: R(e) = Rโ ร qe
โข Feigenbaum ฮด โ 4.6692 โ determines the hard supply cap: ฮด ร 10โถ = 4,669,201 SOST. This is the mathematical limit of the geometric series โ no counter, no tracking, just convergence.
โข Feigenbaum ฮฑ โ 2.5029 โ determines the epoch length: ฮฑ ร 10โต = 131,553 blocks per epoch โ 2.503 years.
Epoch Structure
โข Epoch 0: 7.85100863 SOST/block (genesis reward)
โข Epoch 1: 6.11448985 SOST/block (โ22.1%)
โข Epoch 2: 4.76155747 SOST/block (โ22.1%)
โข ...each epoch decays by the same smooth factor...
โข Epoch 11: 0.60574158 SOST/block
โข ~95% of total supply emitted by epoch ~12 (~30 years)
โข Emission continues through ~82 epochs (~205 years) until rewards become negligible
โข 100% emission is asymptotic โ mathematically approaches but never reaches the cap

Why Feigenbaum?
The Feigenbaum constants (ฮด = 4.6692..., ฮฑ = 2.5029...) are universal mathematical constants from chaos theory that describe the rate at which period-doubling bifurcations occur in dynamical systems. In SOST, they are used purely as irrational constants to set the supply cap and epoch length โ values that cannot be derived from simple fractions, making them resistant to arbitrary parameter choices. The emission curve is deterministic, immutable, and verifiable by anyone from the genesis block.
