Release Notes
This is a runtime only release.
Highlights:
- Incorporate automatic arbitrage logic
- Include novel Global Disputes pallet
- Enable XCM reserve asset transfers
This release contains a number of exciting new features. One of them is the inclusion of automatic arbitrage logic. With the current market-making scoring rule “CPMM”, the sum of the prices of outcome tokens should ideally be 1 to represent a normalized distribution of probabilities. CPMM allows the sum of prices to be greater or less than 1 in specific circumstances.
Arbitrageurs can mint/sell or buy/burn outcome tokens, unfortunately they draw the profits directly from the liquidity providers by doing so. The solution that we have implemented for this issue ensures that the total sum of prices is normalized to 1, while leaving the resulting arbitrage profit in the hands of the liquidity providers.
Another exciting feature released in this update is Global Disputes. Global Disputes is a pallet developed by Zeitgeist whose purpose is to resolve disputed markets in case the original dispute mechanism is not capable of determining the correct outcome. It does so by launching a global token holder vote. The potential outcomes can be provided by anyone. Once the correct outcome is determined, the correct outcome providers are rewarded with the bonds from the providers of the incorrect outcomes.
The last update is a significant step towards Polkadot primary vision, interoperability: The proper configuration of XCM and addition of logic to handle reserve asset transfers of any approved asset. After applying the runtime contained within this release, the Zeitgeist chain is able to open communication channels to other parachains and the relay chain.
Through those channels, any approved assets can be transferred. The possibilities are immensely more manifold, as the messages transferred through those channels could theoretically realize any state change in the consensus system in which they are interpreted. Those are interesting goals to work towards, and this release sets the first step in this direction by adding logic to properly receive and transfer any approved asset!
In addition to those considerable updates, the codebase was upgraded and the usability of the protocol was improved.
