Peercoin v0.9 (Codename Strider) Released - Hard Fork is June 8th, 2020 - Upgrade Today!

Peercoin v0.9 Released!

We are pleased to announce that after many hard months of work, Peercoin v0.9 (Codename Strider) is complete and a hard fork is planned for Monday, June 8th, 2020 at 12:00:00 UTC. You must upgrade your wallet client before then!


Peercoin release v0.9.0

  • RFC-0019: PoW Block Spacing
  • RFC-0018: PoS Rewards Adjustment
  • RFC-0017: Limit Effective Coinage to One Year
  • RFC-0015: Reduce Time Drift
  • allow staking=0 command to disable minting
  • ability to filter out mint transactions in the QT wallet




Upgrade Instructions

Before installation, make sure to backup your wallet from the main menu.

The v0.9 client can be downloaded from the wallets page of For users upgrading from v0.8, upgrade instructions can also be found on that page.

Additionally, it is recommended that a resync of the blockchain is performed after installation. If you are installing a fresh copy then you don’t need to worry about this step. If you are upgrading from v0.8, then you can resync the client by going into your Peercoin installation directory and deleting two folders called blocks and chainstate (nothing else), and then restarting your client to let it resync.

For the minority of users that may have skipped v0.8 and are upgrading from v0.7 or earlier, please check these additional instructions from the previous v0.8 release thread as you will need to go through the additional process of rebuilding your block database. If you need help with installation, leave a comment below.

Hi mate I can’t believe that You are still here. I can see you really love peercoin but I have to say that peercoin really have let you down.

The only thing that lets me down are people who endlessly complain without putting in any effort. I’m here because I know Peercoin, both as a blockchain and a cryptocurrency, are superior to most of the garbage that is being pushed today. And we will keep improving this network and pushing it forward until it is recognized.


Actually, you haven’t been around in a while and probably haven’t seen this. Try checking out the 5 part intro series we recently produced with Chronos here…

This seems like a longer path.
