BIT-8008: veAlpha Governance Layer — Vote-Escrowed Subnet Governance with Liquidation Auctions

[0xVonBismarck]

Summary

This BIT proposes the veAlpha governance layer for Bittensor — a vote-escrowed subnet governance system with liquidation auctions.

• veAlpha voting power is derived from locking a subnet's Alpha token for up to 4 years, with linear decay — tying governance influence directly to long-term economic commitment.
• Liquidation challenges allow the community to democratically challenge misaligned subnets through bonded proposals and veAlpha-weighted votes. Successful challenges trigger a Dutch auction for the subnet slot, preserving value through orderly transfer rather than destruction.
• Hyperparameter governance extends the same bonded-proposal framework to let committed stakeholders propose on-chain configuration changes.
• Root staker participation gives TAO stakers an 18% network-level voice in subnet governance via a gauge-style allocation mechanism.

Motivation

Bittensor currently lacks a formal governance layer for subnet oversight. Subnet owners receive 18% of emissions, control hyperparameters, and occupy scarce network slots — but face no structured accountability. Recent incidents (Covenant AI mass-liquidation, Subnet 29 governance failures) illustrate the risks. The only existing removal mechanism is price-based deregistration, which creates strong incumbency bias.

This proposal introduces a market-driven, time-weighted governance layer that enables the network to democratically prune or transition subnets without requiring price decay.

Key Sections

• Specification: veAlpha locking mechanics, root staker participation, liquidation challenges, subnet owner defense, Dutch auction, auction resolution, hyperparameter governance, incentive dynamics
• Security Considerations: Bond griefing, whale dominance, lock manipulation, gauge-weight manipulation, auction gaming, cold key swap security
• Implementation Paths: Native Subtensor pallet (runtime upgrade) or SubtensorEVM smart contracts
