  • 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

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.
