  • 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 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 Coin Core] Ongoing investigation into potentially erroneous balance reported by paicoin-cli for solo stakers;
    • Implemented wallet transactions cleanup for stake vouchers that are expired or no longer in the mempool. This impacts balance calculations and will “free” any lingering funds in the wallet;
    • Added descendants cleanup for these transactions;
    • Working on updating the wallet’s ordered lists of transactions to be consistent with the general map, these diverged due to the aforementioned changes;
    • Finalizing implementation of unit test suite;
    • Preparing minor release v2.2.0
  • [PAI Coin Pool] Awarded promotional staking bonuses, see details above
  • [Catena NFT Art Marketplace]

    • Finished adding support for multiple oAuth attributes in one request
    • Added the ability for third party applications to request a user’s Paicoin address via oAuth
