200,000  – Project/dev expenses – the only part of the premine taken by the team, it was used for server expenses
300,000 – Nebulous Inc Original blockchain development
This and SPF drop showed us as a supportive/friendly fork. Nebulous provided an address they knew they no longer had keys to. DYOR.

Project Fee

20% thru month 6, declining to 10% over 2 years
After block 105,000, the 10% project fee was sent to an unspendable address (burn) to reduce inflation/supply for the duration of the project

Supply Precision – The base unit of the ScPrime coin supply is 24 decimal places or 10^24. A precision change was done early on – Supply Change Guide

Emission/Inflation Schedule 

ScPrimeFunds

10,000 ScPrimeFunds (SPF) were initially created and distributed to holders of record at the open source software block 179,000.

At block 59550, a hard fork created an additional 20,000 SPF

At block 109,000, a hard fork changed total emission to 200,000,000 and set the tax rate across the entire population at 10%.
A number of units have been given away to various entities including the angel investors in SCP, Corp. There can be no further negligible change to the supply without significant consensus from a number of parties. 200m is considered the final emission.

Storage Network Fund

Network Incentive 1 has been opened to provide initial rebates on Xa-Miners and ongoing Storage Provider Incentives
