12/4/19 Update: Thank you to one of our community members who has identified a potential security vulnerability. Coming back from the Thanksgiving holiday, our team investigated this yesterday and has confirmed that it needs to be addressed. Since we want to be cautious and diligent about preserving network stability and token value, we are moving the date of enabling token transfers to December 17. Please visit Kadena’s Discord channel to share your comments and questions.

As part of our ongoing efforts to keep the community informed, we are sharing the release schedule for Kadena 1.1, which enables coin transfers on the Kadena public blockchain. After the initial release, the transition from version 1.0.5 to 1.1 will take place over three stages from December 2 to December 6, 2019, followed by a ramp-up period of transfer volume.

Kadena 1.1 Software Release (December 2):

  • Kadena 1.1 is required to operate the blockchain after the rollover is complete.
  • It contains the necessary protocol changes to allow coin transfers on the platform.
  • It also contains important improvements and fixes for the protocol, P2P layer, transfer performance, and stability.

Soft Rollover Stage (December 2–5):

  • Kadena versions 1.0.5 and 1.1 are both fully operational and cross-compatible.
  • Both versions continue to mine empty blocks only (no transfers).
  • Miners are encouraged to update as soon as possible so we can address any unforeseen issues with the upgrade in the soft rollover stage.

Hard Rollover Stage (December 5–6):

  • All Kadena versions 1.0.x will stop mining new blocks at 00:00 UTC December 5. Miners will have to upgrade at this point to keep mining.
  • Kadena version 1.1 will continue to mine empty blocks as before.

Kadena 1.1 Transfers Enabled (December 6):

  • At the end of the hard rollover stage, the Kadena blockchain will start accepting coin transfers and other coin-related operations.
  • We will provide documentation on methods for performing transfers.

Transfer Limit Ramp-up

Building on the success of the limited beta release on October 30, the Kadena 1.1 blockchain will gradually ramp up transfer throughput over the following weeks after December 6, so we can continue to address issues that might arise with the new functionality.

On December 6, Kadena 1.1 will have a low gas limit that defaults to approximately 10 transfers per block. We plan to increase this limit periodically with close coordination with the mining community on an approximately weekly basis. Initial increases will result in block transfer limits of 25, 50, etc. We expect to continually release upgrades during this time to improve transfer handling and enable greater throughput.
