PAI News :newspaper: - December 14, 2020

37th Edition

Announcements :speaker:

: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
git pull # pull the latest changes from the paicoin repo
git checkout 2.1.0 # switch to the latest release
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:

  3. Upload the script to the full node you use for staking, or;

  4. Copy and paste its contents into a new file on the full node named voter_check.py

  5. Run the following commands to execute the script with the correct dependencies (these commands assume that voter_check.py 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 …
    python3 voter_check.py

You can also download the Android APK version and follow the mobile wallet links on paiup.com

  • A demo version of the The PAI Data Protocol is now available to test, enabling users to try to encrypt and store data using the PDP2 protocol specification. It’s currently used for services such as PAI Pass.

  • :money_with_wings: 1% PCP staking bonuses from the promotion announced in the 11/30 Newsletter will be paid out this week!

Promotions :red_gift_envelope:

  • Set up a full node and earn a PAI Coin Pool bonus of 666 PAI! Set up a full node according to these instructions, then email promotions@projectpai.com from the email address associated with your PCP account. In the email, include the IP address or URL of your full node. We will reply with further instructions on how to claim your reward.
  • Create a pre-compiled binary version of paicoind for others to use and get rewarded 10,000 PAI Coin! We want to make it easier for community members to run full nodes and to solo mine and solo stake. One of the ways we can do this is by providing precompiled binaries of the PAI Coin Core software (which comprises paicoind and the paicoin-cli) so that users don’t have to compile the software from source.
    • In order to participate, email a link to download your pre-compiled binary (either for Linux, macOS, or Windows) to promotions@projectpai.com. The first three valid entries received for each platform will be eligible for the reward.

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.

PAI Developer Updates :computer:

Here’s a snapshot :camera: of development work the team has been focused on:

  • [PAI Coin Core] Ongoing investigation into potentially erroneous balance reported by paicoin-cli for solo stakers;
    • added available_balance and legacy_balance to the getwalletinfo command response;
    • wrote comprehensive documentation on the different categories of PAI Coin balances in the full node CLI wallet (to be released)
  • [paichain.info] Investigated why the mempool on paichain.info is so large;
    • determined that paichain.info was not updated to expire transactions from its internal cache, thus causing paichain.info to continue to display previously expired stake voucher purchase transactions;
    • solution is processing and will be deployed this week
  • [PAI Coin Pool] preparing, validating and awarding promotional staking bonuses
  • [Catena NFT Art Marketplace] Improvements to the DM (direct message) functionality and design, added a thumbnail selection modal for the asset upload flow, added custom redirects for errors, enhanced the querying API for the homepage – to enable additional sorting options instead of just recent uploads, as well as pagination for the gallery.
