Release Notes
Upgrade Priority: Medium (timely upgrade recommended)
Highlights:
- Implement Automated Market Maker (AMM) 2.0 Lite
- Implement Orderbook Lite
- Implement Trusted Markets
- Update dependencies to polkadot-v0.9.38
Implement AMM 2.0 Lite
While the current AMM has proven to be highly stable and functional, we’ve also noticed that it is inefficient and incapable of serving the complete spectrum of prediction market applications.
With this in mind, AMM 2.0 “lite” has been designed as a first step in improving the algorithmic trading mechanism to be more efficient with liquidity, extendable and capable to serve advanced prediction markets such as combinatorial markets.
AMM 2.0 Lite provides a partial implementation of an internally researched pool-based variant of the LMSR AMM, which enables the utilization of LMSR’s elegant and efficient algorithm for binary (two category) markets.
Implement Orderbook Lite
Order books are a well known structure to balance supply and demand. This release allows the creation of markets which use an orderbook as the method of exchanging outcome tokens.
Implement Trusted Markets
It is sometimes necessary to quickly host and resolve a market. In order to serve this purpose; Trusted Markets grant the oracle the privilege to be the only entity to report the final outcome. In addition to this, the market immediately resolves after the report.
Update dependencies to polkadot-v0.9.38
The most prominent features of polkadot-v0.9.38 are the transition to a more precise weight system called "WeightsV2", and the next iteration of the Cross-Chain Message (XCM) format "XCMv3".
WeightsV2 better estimates the resources required on the blockchain, which is used to calculate execution fees amongst other benefits.
XCMv3 also provides a multitude of new and exciting features like support for external ecosystems (like Ethereum), programmability and remote asset locking.
