After lots of development and testing efforts we are excited to propose the next major Oasis Network upgrade named Damask!
All features for the Damask upgrade are implemented as part of Oasis Core 22.1.x release series which is a consensus protocol-breaking release.
Summary of the major features is as follows:
Random Beacon: The random beacon is used by the consensus layer for ParaTime committee elections and is a critical component in providing security for ParaTimes with an open admission policy. To make the random beacon more performant and scalable, the upgrade transitions the election procedure to one that is based on cryptographic sortition of Verifiable Random Function (VRF) outputs. For more details, see ADR 0010.
On-Chain Governance: The upgrade simplifies the governance by replacing separate quorum and threshold parameters with a single unified stake threshold parameter that represents the percentage of yes votes in terms of total voting power for a governance proposal to pass.
ParaTime Performance: By simplifying the protocol (executor and storage committees are merged into a single committee) the upgrade improves ParaTime committee performance and opens the way for even more improvements on the ParaTime side. It also leads to simplified configuration of ParaTime nodes.
ParaTime Upgrades: After the Damask upgrade, runtime descriptors will include information regarding supported versions, and the epoch from which they are valid, which will allow ParaTime upgrades to happen without incurring downtime by having upgrades and the descriptor changes pre-staged well in advance of the upgrade epoch. For more details, see ADR 0013.
ParaTime Packaging: This upgrade changes runtime bundles to be unified across all supported TEE types and self describing so that configuring ParaTimes is only a matter of passing in the runtime bundle file.
Consensus and ParaTime Communication: The upgrade adds support for incoming runtime messages where consensus layer transactions can trigger actions inside ParaTimes. For more details, see ADR 0011. The upgrade also adds support for runtime message results which extends the results of the emitted runtime messages with relevant information beyond indicating whether the message execution was successful or not. For more details, see ADR 0012.
In addition to the specified additional features, we also propose the validator set size to be increased from the current 110 to 120 as discussed in the Oasis Community Slack #nodeoperators channel.
This upgrade marks an important milestone for the Oasis Network, as it sets the foundation for unlocking the network's full capabilities.
Next Steps
The upgrade has been extensively tested internally and on the Testnet. Barring any critical issues discovered at the last minute, we believe the upgrade is ready to be performed on Apr 11, 2022.
We will also be posting additional details regarding the upgrade procedure and a summary of the genesis changes.
Behind the Name
Last year our community voted for the Rose colors theme as the winning naming scheme for network upgrades.
The names are alphabetical, with Amber Network being Upgrade A, Mainnet Upgrade B and Cobalt Upgrade C.
For Upgrade D we chose Damask. The Damask Rose is a sweet-scented rose with pink or light red velvety petals.
Damask has a unique meaning as a Rose color: 'Damask Rose symbolizes beauty and love. The fragrance of the rose has been captured and preserved in the form of rose water by a method that can be traced to ancient times in the Middle East and later to the Indian subcontinent.'

The Oasis Protocol Foundation has submitted an upgrade governance proposal and node operators now have 1 week (until Mar 31, 2022) to vote on the upgrade proposal.
