Bittensor validator warns Root Reborn proposal carries “substantial” risks

Yuma, one of Bittensor’s largest contributors and the network’s third-largest validator, has published a detailed critique of the proposed “Root Reborn” upgrade, arguing that the design introduces governance, regulatory, and market structure risks that outweigh its potential benefits. Summary Yuma has opposed Bittensor’s proposed Root Reborn upgrade, warning that it could introduce conflicts of interest, regulatory concerns, and new risks for stakers. The proposal would allow validators to allocate root staking rewards across subnet tokens instead of automatically converting rewards into TAO. Yuma said subnets backed by validator allocations could benefit from additional demand, but called for more testing, risk analysis, and a formal upgrade roadmap before deployment. The proposal, currently under review and not yet active on mainnet, would overhaul how root staking rewards are handled. Under the existing system, root dividends are effectively paid by automatically converting subnet alpha emissions back into TAO. The new design would stop those automatic sales. 🧠 Bittensor $TAO upgrade watch: Root Reborn A new Subtensor PR proposes one of the larger changes to Bittensor’s root validation structure so far.

Root emissions would then be deployed into validator-selected baskets of subnet tokens, with stakers receiving redeemable claims on those positions rather than direct TAO rewards. The proposal states that the change would reduce automatic sell pressure on subnet assets and make validator allocation decisions a more important part of the network economy. It would also introduce new tools to track validator basket net asset value, subnet allocations, staker liabilities, and network-wide basket performance. Yuma said the proposal changes the role of validators from infrastructure operators into active allocators of capital. “In its current form, the Root Reborn proposal carries substantial unmitigated risk that outweighs its benefits,” the validator group wrote. The following analysis is a byproduct of lack of process within the ecosystem that leaves business builders limited notice or ability to properly plan, assess risk, and execute.

The group said validators could direct allocations toward subnets in which they already hold positions or accept external incentives from subnet operators seeking additional capital. Yuma compared the structure to the lessons of the LIBOR scandal, where a small group of participants held influence over key financial benchmarks.
