Release Notes

Upgrade Priority: ❗ HIGH ❗ Please upgrade your node as soon as possible.

Highlights:

• Use new dispute system design (ZIP-0)
• Implement Court dispute mechanism (ZIP-2)
• Enable global disputes on mainnet
• Add market creator incentives
• Update codebase to polkadot-v0.9.38

Use new dispute system design (ZIP-0)
The dispute system was reiterated. It now offers a proper API to control dispute cases, which allows a flexible and clean extension of the prediction market protocol by new pallets that handle disputes. This was a prerequisite to properly implement the Court pallet, which is part of this release and enabled on Battery Station.

Implement Court dispute mechanism (ZIP-2)
Court is a decentralized and permissionless dispute mechanism that tries to solve the problem of determining the true outcome of a market. A detailed explanation of the functioning of the Court dispute mechanism can be examined at Zeitgeist documentation. The (unlikely) situation can occur that the Court dispute mechanism is unable to determine the correct outcome. In that case it utilizes the global dispute mechanism as a final resort.

Enable global disputes on mainnet
Global disputes is now enabled in the Zeitgeist runtime as well. It provides the protocol with the ability to determine the true outcome by spawning a global token holder vote.

Add market creator incentives
The creator of a market now has the ability to specify a market creator fee percentage within certain boundaries. Each trade that happens in the context of that market is additionally charged with the market creator fee associated with the respective market. The fee is transferred to the market creator.

Update codebase to polkadot-v0.9.38
As Zeitgeist's dependencies are updated to polkadot-v0.9.38, the protocol starts utilizing XCMv3 and the new more advanced weight system Weightsv2.
