Community action needed for PAC Protocol Mainnet Update Phase 1!

7 min read

The new update of the PAC Protocol Mainnet is complete (07/02/2022)!

The highly anticipated Mainnet update on PAC Protocol is ready for a two phase roll-out. It fixes two main problems, it fixes the Masternode POSE score issue in Phase 1 and then provides the long awaited token layer. We need the community's action to get network consensus. The faster we gain network consensus on Phase 1, the faster we can roll-out Phase 2, as one needs to be completed before the other. The phase 1 release is version v0.17.0.5, this version introduces new quorum sizes and a new fee structure. You can help by implementing v0.17.0.5 right away! Once we reach community consensus, we can release Phase 2, the version that introduces the token layer.

We have set out multiple checkpoints to determine whether consensus on the network has been reached - if our community is fast, this roll out will be fast! We will let the community know on those days to let know if consensus is reached, and if so, Phase 2 will be released:

Checkpoint dates:

  • July 5th, 2022

  • July 10th, 2022

  • July 15th 2022

  • July 20th 2022

  • July 25th 2022
