:warning: PAI Coin 2.1.0 is here! UPDATE TODAY. :warning:

:rotating_light: If you are running a full node, solo staking, and/or solo mining, you must immediately update to 2.1.0. :rotating_light:

To update, execute the following commands in the paicoin directory of your full node.

paicoin-cli stop  # stop the node from currently running

make clean  # uninstall your previous build
make  # compile the new release
sudo make install  # install at the system level
paicoind  # restart your node

:point_up: For ALL solo stakers: Make sure your node is online and voting! :point_up:

Execute this script on your staking node.

Here’s how:

  1. Download the script from here.
  2. Either:
  • Upload the script to the full node you use for staking, or;
  • Copy and paste its contents into a new file on the full node named
  1. Run the following commands to execute the script with the correct dependencies (these commands assume that and your paicoin directory are both located in your user home directory (~), and that your user home directory is your present working directory, pwd):

    sudo apt install python3
    cd paicoin
    sudo make install
    cd …

Staking on PAI Coin Pool :bank:

Staking on PAI Coin Pool works via a mechanism called Staking By Proxy. Staking By Proxy functions by pooling together all staked user funds in order to purchase more and higher-valued stake vouchers on the PAI Blockchain. Rewards are then distributed among stakers proportional to the amount their stake contributed to the pool. This mechanism is particularly beneficial for users who may not own enough PAI to purchase at least one stake voucher on their own, e.g., because the stake voucher price is too high. On the other hand, when the stake voucher price is low, there is little advantage to having a large pool of funds, since, by rule, the total number of stake vouchers that can be purchased across the entire network is limited to 20. So, as the stake voucher price increases, the advantages (and reward amounts) associated with PCP staking will increase substantially. For more information, see last week’s newsletter.

PAI Coin Pool Stake Voucher Stats

  • Current Stake Voucher Price: 29,663 PAI
  • Percentage of live Stake Vouchers owned by PAI Coin Pool: 29%
  • Total number of live Stake Vouchers: 69,243
  • Total amount of stake rewards earned by PAI Coin Pool to date: 1.37 million PAI

How to connect PAI Up Mobile to a specific node :face_with_monocle:

Follow these instructions if you are unable to sync PAI Up or if your PAI Wallet still displays incorrect data after a sync.

Traditional apps, like WeChat, connect to a central server to retrieve and upload new data like incoming and outgoing messages, or new Moments from other users. PAI Up doesn’t work like that. Since the PAI Blockchain is a decentralized peer-to-peer network, there is no central server. But every PAI Coin Full Node acts like a central server, and when you launch PAI Up, the app has to choose—basically, at random—which Full Node to connect to.

If your connection to the node is poor (for example, because it’s physically far away), or there happens to be something wrong with that node (for example, because its owner is not properly maintaining it), PAI Up might not work well. In this case, you should manually reconnect to a different node. Here’s how.

From the main screen of PAI Up → Menu → Preferences → PAI Coin Settings → PAI Coin Nodes.

Now, take note of the “Current Primary Node,” then choose “Switch to Manual Mode.” From there, enter one of the following nodes (one that doesn’t match the Current Primary Node from the previous screen) in the top field and choose “OK.” You can enter either the URL or the IP address directly. Then, make sure the “Node Connection Status” shows “Connected.” If it doesn’t, or if it oscillates between “Connected” and “Connecting,” choose a different node from the list below and repeat the process.

:point_right: If these tips still don’t work, try uninstalling and reinstalling PAI Up.
