A new coin, Pigeoncoin, was quietly launched on March 21, 2018 claiming “inspiration” from Ravencoin and uses a variant of the x16r algorithm Ravencoin introduced.

Pigeoncoin differs from Ravencoin mainly in the fact that it utilizes a new algorithm called X16S (shuffle). Instead of randomizing the algorithms to use from a list of 16 sub-algos like x16r does, the x16s algo instead “shuffles” the list to call the sixteen sub-algos. The result is that every sub-algo will run on ever iteration, instead of a random grouping like with Ravencoin. The justification is that it evens out the hashrate and power spikes making it easier on miners.

A graph (below) from the Pigeoncoin team illustrating this smoothing effect from comparison test runs show the more consistent hash rare obtained with the x16s algo.

Despite its quiet launch, Pigeoncoin picked up steam pretty quickly, mainly due to its being mentioned in the Ravencoin Discord community. CPU mining was possible using the wallets built-in miner for the first few days, but then users noticed a majority of the hashrate and blocks were going to one address.

Realizing that someone had developed a GPU miner already. BrianMCT, who also developed the Nevermore miner for Ravencoin jumped into action and modified his nevermore code to utilize the x16s ordering. As soon as this was released a pool opened up and many more miners joined in the action.

The whitepaper detailing the X16S algorithm can be found at: https://github.com/Pigeoncoin/pigeonbrand/blob/master/X16S-whitepaper.pdf

The algorithms used in x16s are the same ones used in x16r and are as follows:
0 blake 8 shavite
1 bmw 9 simd
2 groestl A echo
3 jh B hamsi
4 keccak C fugue
5 skein D shabal
6 luffa E whirlpool
7 cubehash F sha512

To mine Pigeoncoin, you can download the wallet and mining software in the links below.

If you have questions on how to set everything up, since it is very similar to Ravencoin you can follow my How to Mine Ravencoin on Nvidia guide, simply substitute by using the Pigeoncoin wallet and mining software instead.

UPDATE on Wallet Peers

Due to the age of the network your wallet may have trouble finding peers to connect with. To manually add more peers to help the client connect to the network you can do the following procedure:


First go to the Help->Debug window as shown above.

This will open up a page similar to the one shown in the above image. This window will give you a overview of your wallet as well as some information about the network.

I highlighted in red (above) the current number of connections the client is connected to, which in this case is just one, normally you would want to see 8 or more connections here.

If you go to the Pigeoncoin block explorer there is a network page http://explorer.pigeoncoin.org/network which lists nodes or “peers” that are connected to the explorer.

You can use this list to help add a few new connections to your client. You will notice that the list shows the IP address as well as the country of the peer. Pick one or two nearby nodes off of this list that are either in, or near, your own country and record their IP addresses. You can also just leave the page open to reference for the next step.

Click on the Console tab in the Debug window as shown above. Here we have access to the CLI commands of the GUI wallet, so we can manually add new peers or nodes to our wallet.

Type in addnode <ip address> add in the input box and hit enter, where <ip address> is the IP address of the peer you recorded previously.

In the example above I used: addnode add

NOTE: A full time Seed node has now been added to the network: use seed.pigeoncoin.cc:6969 or addnode seed.pigeoncoin.cc:6969 add to your peer list.

You will need to add the nodes one per line, one at a time, hitting enter after each entry.

When completed you should see a confirmation in the display with a return value of null, as shown in the example above. The null return value simply means the command completed with no issues. If it did return an error it would also display it in this same window.

After entering one or two new peers, you can go back to the Information tab, or alternatively the Peers tab to confirm the nodes were successfully added and are now connected. Note that it may take a minute or two to establish a connection, and if the peer is busy it might refuse to join. In this case, simply go back and add a couple of more peers.

  1. RudeHash 8.0 released just yesterday with PGN support (BSOD/Suprnova pools, nevermore/suprminer miner support). It’s very easy to get going with it, you folks might wanna give it a try 🙂

  2. “quietly launched” my a**!
    They mined for 6 days (March 21st 2018 – March 27st 2018) before making any public announcement and that’s probably 50 million coins which is more than 25% of current supply (180 million).

    It is even stated in their ann:

    “On day five, I asked our group of twelve to start onboarding more miners…”
    So, 12 people mined for days before any announcement!

    Maybe you should check your facts before stating “Premine: No”!

    • Pre-mine typically refers to when the developers actually mine a bunch of coins ahead of time for the purpose of funding future developments, bounties, airdrops and the like, in which case Ravencoin did not.

      Anytime a coin launches it will have some people with first mover advantage and it was no different than with Ravencoin. Also, Bitcoin was launched under basically the same conditions with just a handful of people mining blocks by themselves for several months, so I do not really see the difference. With a supply of 21 Billion coins, even if they did mine 50 million, that would equate to roughly 50,000 Bitcoin in its earliest days. While that may seem like a lot now, remember Bitcoin was only worth pennies at the time, remember the 10,000 BTC pizza story?

      During the early RVN trading you could pick up RVN for well under 1 cent each, so even if you missed out on the early mining you could still accumulate a nice amount for low cost. So with all these factors, I am not really sure what your complaint is as a lot of other coins have launched with a lot less “fair” conditions.

  3. Was going to make a backup of my PGN wallet and my PGN wallet crashes now when opening it up. It starts to try to load the latest block info and then “Stops Working” and I have to kill the process.

    • You can make a backup without the GUI running. By default, the wallet.dat file should be located in C:\Users\\AppData\Roaming\Pigeon folder. Just copy the wallet.dat file somewhere else, like to another hard drive or USB thumb drive, multiple copies is even better.

      To fix your syncing issue, you can also try deleting all the other files within the same folder, just leave your wallet.dat file intact, and relaunch the PGN client. It will re-sysnc from the beginning thus rebuilding any corrupted parts. The only file that you need to backup and be careful with is your wallet.dat as that is what contains your private keys that any funds you have are stored on.
