This release adds support for reward lock and signed mining, preparing them to be proposed through Kulupu's on-chain governed runtime upgrade. It also contains several changes that improves mining and syncing performance. The memory requirement for non-mining node is significantly reduced as well.

Note that for mining nodes this is a backward incompatible change, as you will need to import mining key to the node for the mining function to continue to work. Please read the migration section for more information.

  • Added support for signed mining in consensus engine, and reward lock in runtime.
  • Added a new bootnode sponsored by the community, improving initial syncing performance.
  • Improved several RandomX config flags for better mining performance.
  • Improved syncing logic. Use light mode RandomX verification for syncing. This significantly reduces memory requirements for non-mining nodes.
  • Fixed CI binary build "illegal instructions" error, by building RandomX with ARCH=default.

Migration

If you use Kulupu to mine, from v2.0.0 we require you to import the mining key for the mining function to work. If you do not do this, the node will continue to sync with the network but will refuse to mine any blocks. The mining key is not yet used until the signed mining runtime upgrade is activated.

To import the mining key to your node, please use the import-mining-key command.

kulupu import-mining-key "<secret seed>"

Alternatively, you can generate a new mining key directly using the node.

kulupu generate-mining-key

It will output the secret seed of the mining key. Please keep the seed in a private and secure place.

When signed mining is activated, you can use the same mining key on multiple different nodes. As each node will store the mining key, please take necessary precautions to keep your keys secure.

After importing or generating the mining key, you can use your existing flags for mining to start your nodes as normal.

kulupu --validator --author <address or public key of the mining key>

Public testnet for signed mining

This release also adds a public testnet breaknet4 with signed mining and reward lock enabled. You can use it to test out your setup to prepare if and when signed mining runtime upgrade is activated. To be on breaknet4, use --chain breaknet4 command line flag.

kulupu --chain breaknet4

Note that mining keys for breaknet4 and mainnet are stored separately, so you will have to import mining keys specifically for the testnet, still with the --chain breaknet4 command. For example, if you want to generate a new mining key, use the following command:

kulupu generate-mining-key --chain breaknet4
