You are correct! Burst originally was created as a ICO with premine. year later the dev disappeared without a trace. since it was open source, the community took it over, and concerns addressed by the spacemint whitepaper were merged. Spacemint does not exist as its own coin. But I did do some digging and found the Proof of Space whitepaper from the original iteration. Ill add that in and have both linked.
