Jelurida has created a new type of "coinleft" license, in the spirit of the GNU General Public License, but better suited to protect the interests of open source cryptocurrency projects.

The main idea of the Jelurida Public License (JPL) is not only to ensure that the source code of any work based on a work released under this license remains open, and remains released under the same license, but also to make sure that the community of the original blockchain token holders also receives back some of the new token value created by any such derivative projects, if those have opted to create their own blockchain instead of using the blockchain instance for which the original software is being developed. This is achieved by the JPL airdrop requirement of Article 3.4.1 of the General Conditions.

We have published a summary of the most important requirements of the JPL as the JPL FAQ.

The full text of this license is included below. To make the license text reusable for other projects, it has been divided into General and Special Conditions, allowing such projects to reuse the General Conditions text and only to adapt the Special Conditions to fit their specific blockchain platform.

Starting from version 1.11.6, the Nxt Reference Software (NRS) is the first software to be released under the Jelurida Public License, with the Special Conditions requiring a 10% airdrop to the NXT holders from Nxt clones.

The Ardor Blockchain Platform software is also released under the Jelurida Public License, with the Special Conditions requiring a 10% airdrop of the clone's forging tokens to the IGNIS holders.
