On March 21st 2018 Pigeoncoin was launched as a proof-of-concept network for a new algorithm called X16S (shuffle). Pigeoncoin is a forked-fork of Bitcoin. We do everything on Discord. https://discord.gg/SZcf63h
I didn’t want a big richlist so I tried to bring CPU miners in on day one while handling the to-do list. On day five, I asked our group of twelve to start onboarding more miners… the word spread like wildfire through the Ravencoin community. Hashrate jumped from 1.5 MH to 20 MH in an hour, and membership jumped to 100.
The next day, last night, a GPU randowhale nearly burned down the network. @brianmct bailed everyone out with his quickly patched nevermore Nvidia GPU miner. We have one pool up and more are coming. We wanted more time on CPU mining but it just wasn’t in the cards. Hashrate is now 9600 MH and we have ~300 members.
The network has been active for six days. We’ve been out straight since launch. I apologize for not posting sooner. The last 24 hours have caught us with our pants down. After posting this [ANN] I’m going to bed. I hope everyone else is, too.
Why did all this happen so fast?
I was an early miner on the x16r (random) Ravencoin network. x16r uses the last sixteen digits of the previous block hash to call its sixteen sub-algos. This pseudo-randomness is said to improve ASIC resistance.
I noticed that x16r GPU miners experience fluctuating power and hashrate. I figured this was because each algo used different amounts of power, and if the hashcycle composition was majority high power algos by chance, it would cause the power to rise. I found the uncertainty made it hard for miners to tune their system, while reducing the efficiency and potentially the lifespan of power supplies. I felt the total cost of mining with x16r could be improved.
My solution was to use the same last sixteen digits to reorder a list of all sixteen algos, and then use that “shuffled” list to call the sixteen sub-algos. The result is a hashcycle with every sub-algo represented once. The composition would be constant, but the randomness would be preserved.
This gave birth to X16S (shuffle) which maintains the legendary randomness of x16r while providing consistency for hashrate and power demand.

We have a 1 minute block time, 5000 PGN reward, 21B cap, 2016 block retarget, 16 shuffled algorithms (X16S shuffle). There was no genesis block reward. There was no premine.

Our initial goal was to prove the algorithm works as intended. Well, we proved success two weeks ahead of schedule thanks to our community, so now we get to try to catch up in all other areas! Expect an official announcement regarding roadmap very soon.
