It’s hardfork time again! The Hefty Heimdall upgrade period has begun, and that means everyone has approximately 12 days to upgrade to the latest versions of the Loki software before the hardfork on July 24.
Below is a guide on how to prepare for the hardfork for each type of user in the Loki ecosystem:
You guys don’t need to do anything yet. Over the course of the next two weeks we will be pushing updates to the Loki Desktop, iOS and Android wallets to upgrade them to the latest versions of the Loki software.
Once these updates are released we encourage everyone to upgrade their wallet to the latest version, otherwise you will no longer be able to send transactions on the correct chain.
Service Node Operators
If you are using the Loki Launcher you can update to the latest binaries by using these commands: https://lokidocs.com/ServiceNodes/SNFullGuide/#updating-your-binaries.
For those more experienced with system administration and who aren’t using the Loki Launcher, you can upgrade your lokid binaries manually. Please note that you will also need to update to the latest Loki Storage Server. We have compiled a guide here: https://lokidocs.com/ServiceNodes/SNFullGuideLegacy/.
Pools do not need to enable RandomXL support until the hardfork on July 24 or at block 321467, however they should make sure they are ready to switch when the fork happens, and can look at these two reference implementations for changes they may need to introduce to their software.
A cryptonote-node-JS reference implementation pool which supports the new RandomXL Loki hashing algorithm can be found here: https://github.com/jagerman/cryptonote-nodejs-pool/tree/randomx.
A reference implementation for node-cryptonight-hashing can be found here: https://github.com/jagerman/node-cryptonight-hashing/commits/master.
A list of the full Loki changes to RandomX can be found here: https://github.com/loki-project/loki-randomXL.
Miners can continue to mine Loki using CN-Turtle, however on the July 24 at block height 321467 they will need to switch to using RandomXL which is supported in a mining software called Xmrig on their “evo” branch: https://github.com/xmrig/xmrig/tree/evo. Xmrig have not yet published release binaries with RandomXL support, and if they haven’t published release binaries by the hardfork, we willl build and distribute mining binaries from a fork of their repository.
Exchanges will need to update their lokid and wallet with the latest CLI binaries found here: https://github.com/loki-project/loki/releases/latest. We will reach out to exchanges individually with any additional instructions if required.
