Yuma Consensus v3 (available for all subnets)
- Per-bond EMA scaling: individual & sparse-mode bonds now adapt via exponential moving averages for smoother rewards
- Refactored α-parameters (including new sigmoid-steepness tuning) for fine-grained consensus control
- Monte Carlo scenario tests & map_consensus.py integration tests validate retention guarantees under adversarial conditions
- On-chain toggle event & ABI support to enable/disable Yuma3 per subnet for easy rollbacks
- https://github.com/opentensor/subtensor/pull/1593
Notes for Subnet Owners
- Yuma 3 should be beneficial and safe to use in model verification subnets (specifically subnets which guarantee that a change in miner performance happens with a knowledge commitment), provided the bond reset flag is used correctly.
- It will distribute dividends to the validators more fairly than Yuma 2 did and Liquid Alpha 2.0 allows the subnet owners to disincentivize weight copying.
Generic Crowdloan Pallet (live for public testing)
- Launch generic crowdloans via a simple balance-transfer + arbitrary extrinsic wrapper—supports create, contribute, withdraw, refund & finalize flows
- Enforce a 500-contributor cap to prevent unbounded loops and track counts for benchmarking
- Hardened withdraw logic: only the original contributor can withdraw, and creator’s initial deposit is locked until dissolution
- https://github.com/opentensor/subtensor/pull/1503
Notes
The MEV-resistant staking PRs have been pulled back for now while we address some issues pointed out by the community but should be in an upcoming release
