Peercoin v0.11 (Codename Tardigrade) Released - Hard Fork is Nov 1st, 2021!


Peercoin v0.11 Released!

We are proud to announce the release of Peercoin v0.11 (Codename Tardigrade). This is a mandatory upgrade. A hard fork will take place on November 1st, 2021 at 12:00:00 UTC, so be sure to prepare yourself by upgrading before then. Look below for more details concerning this release.

Note: The v0.11 release is named after the Tardigrade, one of the most indestructible animals on Earth, usually associated with Peercoin for having the qualities of a blockchain that is built to last.


  • RFC-0014 - Remove Transaction Timestamp
  • RFC-0022 - Limit PoW Rewards to 50 PPC Per Block
  • Make Splitting Coins Optional During Minting
  • Other Bugfixes


v0.11 builds on the v0.10 codebase by delivering a major change to the Peercoin network, the removal of the transaction timestamp. Why is this removal necessary you may ask.

The transaction timestamp was first implemented in Peercoin by Sunny King. Its purpose was to allow for an easier way to handle coin age in the client. It is a unique part of Peercoin’s protocol which does not exist in Bitcoin. Because of its inclusion however, it has had the unfortunate consequence of rendering Peercoin incompatible with a large number of tools, services, and infrastructure primarily developed for Bitcoin. As a result, integrating Peercoin with these tools and services requires additional time and effort to be spent on complex workarounds, making the timestamp a burden on our developers.

This upgrade removes the transaction timestamp from the protocol, eliminating Peercoin’s incompatibility issues. Once the protocol switches to v0.11, it will become much easier for developers to integrate with existing infrastructure such as Rosetta, Lightning Network, Atomic Swaps, DeFi, DEXes, and much more. This change will open Peercoin up to many different possibilities for future developments and integrations.

In addition, v0.11 also includes two other changes. The first is the new ability to prevent your coins from splitting once a block is minted. Previously this splitting was automatic, but v0.11 gives you the option to turn it off. Second, v0.11 institutes a new limit on the maximum reward possible for PoW blocks. This limit is set at 50 PPC per PoW block. The purpose of this limit is to shield the Peercoin network from excessive inflation in the unusual case of abnormally low PoW difficulty.

What Comes Next?

The next developments the team will work on concern the integration of tools that were previously incompatible with Peercoin due to the transaction timestamp. We will dedicate resources to implementing Rosetta, which as explained in our 2021 roadmap is a necessary requirement for integration with Coinbase.

Another important development will be the porting of LND (Lightning Network Daemon) to Peercoin. LND is by far the most popular software used with the Lightning Network.


Big thanks to volunteers who have made this release possible:

Lol, that’s a great splash screen :heart:


Fantastic work by all concerned.


Marvelous! Hope we will be able to have a custom build for the Raspberry Pi 2b, like we had for the v0.9


Great work, big thanks to the dev team


Thank you for your persistence!


Awesome, thanks to the team.


Live long and prosper! :vulcan_salute:

Debian repo is now updated to v0.11.

I had to change the signing gpg key again, so do update the key before you proceed to update Peercoin:

wget -O - | sudo apt-key add -


Thank you for all the hard work for this upgrade.


Will the Linux version work on my raspberry pi?

How did you install it on raspberry?

I believe I used the peerbox image

So you have this installed, just update.

Add key, as it says on that link and

sudo apt-get update && sudo apt-get upgrade
