PAI News :newspaper: - October 19, 2020

29th Edition

Announcements :speaker:

:exclamation:Two major software updates are available for you this week.:exclamation:

  • Update #1: PAI Coin Core v2.0.2 :arrow_left:This one’s really important!

    • If you are running a full node, you should update to 2.0.2. If you don’t, you may not be getting the rewards you’ve earned from stake vouchers you’ve purchased!
  • Update #2: PAI Miner v2.0 :arrow_right: Windows | macOS | Linux

    • This version is updated to work with Hybrid Consensus.
    • Older versions of PAI Miner will no longer work with PAI Coin Pool.

Remember! Mining and staking are now PUBLIC.

:earth_americas: Anyone can now mine and stake—including you! :earth_asia:

There are three ways you can mine and stake:

PAI Coin Pool :busts_in_silhouette:

When you mine or stake on PAI Coin Pool, each reward that the pool earns is split proportionally among all users who were actively mining or staking when the reward was won. Read more about mining and staking on PAI Coin Pool here. PAI Coin Pool is the easiest way to get involved in mining and staking; for mining especially, it’s your best option if you’ll just be mining on a small device like a laptop.

Solo Mining :pick:

In PAI Coin Pool mining, you pool your computing resources with everyone else on the pool. When you solo mine, you are mining all by yourself, which means that when you mine a block, you get to keep the mining block reward all for yourself. On the other hand, it might be difficult for you to mine a block depending on how high the network hash rate is (you can see its value under “Network” on relative to how much computing resources you have access to for mining.

Solo Staking :tickets:

When you solo stake, you set up your full node (paicoind) to automatically purchase Stake Vouchers. Every time a new block is mined, five Stake Vouchers are chosen at random. If one or more of your SVs are chosen, you can earn up to 900 PAI Coin when they vote on the block’s validity (voting is handled automatically by paicoind). We’ll be releasing a solo staking guide later this week.

:tada: PAI Up Android is now available in the Google Play Store. :tada:

If you ever have trouble getting your PAI Up Mobile Wallet to sync, try following the instructions below on how to manually connect PAI Up Mobile to a specific node.

There’s more… :grin:

➢ PAI Coin Pool deposits and withdrawals have been resumed. :+1:
➢ Huobi Global is currently working with the PAI core team for final development and testing to resume deposits and withdrawals. The deposit and withdrawal of PAI coin will be resumed soon. Please pay attention to the announcement.

  • PAI Coin Pool deposits and withdrawals have been resumed. :+1:
  • PAI Coin Pool is now mining on-chain! :pick:
    • For every block that PAI Coin Pool mines, 600 PAI Coin* of the block reward allotted to miners will be distributed proportionally across PCP users that are actively mining.
    • For every block that PAI Coin Pool successfully votes on, the amount of the 900 PAI Coin* of the block reward allotted to stake vouchers that PAI Coin Pool held will be distributed proportionally across PCP users that have open stakes.
      • *All rewards are subject to a 2.5% pool fee.
    • will be updated soon to clearly show which blocks were mined by PAI Coin Pool.
      • If you’re curious right now, you can see which block a given mining block reward you’ve received came from by clicking Show Details next to a reward transaction in the Account Activity table on the PCP Dashboard.

:point_right: Check out this information about the ongoing transition to Hybrid Consensus:

:clock4:PAI Countdown has been updated to countdown to the first block reward halving. Check it out! :clock4:

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 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.

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.

PAI Hybrid Consensus

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

  • [PAI Up Mobile] Worked on proper validation rules;
  • [PAI Up Mobile] Worked on extending block storage;
  • [PAI Up Mobile] Implemented chain work calculation;
  • [paicoind] Updated PAIcoinFramework to be able to use the new extended block header and to be able to solve blocks using the new hashing algorithm;
  • [paicoind] Implemented additional functional tests, there are now only 2 remaining;
  • [PoUW] Worked on simplifying PoUW message history by using history Merkle trees;
  • [PoUW] Worked on using Keras instead of MXNet as a higher abstraction layer for ML;
  • [PoUW] Looked into how to solve the network difficulty problem
