This version contains several significant security updates that greatly enhance the network security. The most noticeable change is adjusting Generate ID fee while invalidating all existing node ID. There are two transition block height:
- After block height 2570000, old ID is still valid, but cannot be generated. New ID can be generated after block 2570000.
- After block height 2600000, old ID is no longer valid. Node without new ID will need to generate new ID before joining the network.
To minimize impact on existing network, the NKN Foundation will pay for this new Generate ID fee for all qualified existing nodes, see https://forum.nkn.org/t/security-enhancement-adjusting-fees-for-generate-id/3243 for more info.
In addition, there are a few other updates:
- Enhanced signature chain verification that will be enabled at block height 2570000.
- Add subscriberHashPrefix parameter in get subscribers and get subscribers count RPC.
The new version is not compatible with previous versions starting from block height 2570000. Please make sure all nodes upgrade before this height.
