Shor's challenge branch goes public ahead of Monday deployment, new telemetry dashboard for miners and validators, Phase 2 prize-pool economics for Subnet 63, and Open Quantum nearing Q4 launch with private, beta, and public release stages.

Miner Fairness and Scoring Adjustments

We made targeted adjustments to how new miners are scored and how long the immunity period lasts. Previously, new miners were evaluated against the full 48-hour scoring window, which put them at an immediate disadvantage since they could only accumulate a fraction of the circuits that established miners had completed. The updated model normalizes scoring based on time alive rather than the full window, so new miners can establish themselves on a more level playing field. We also reduced the immunity period from roughly 50 hours down to 36 hours, which means fewer immune miners cutting into the earnings of productive miners while still providing ample time for newcomers to ramp up.

Circuit Timing Investigation

We acknowledged that the community had noticed a slowdown in peaked circuit generation over recent days. While we kept the details light, we shared that we had a strong theory about the root cause -- specifically that a participant appeared to be intentionally slowing down the ecosystem, since fewer circuits at the same emission rate means less compute cost per miner. The Shor's branch and new telemetry tooling were expected to help us confirm that theory. We appreciated the patience from miners as we worked through the issue and the creativity from the community in finding novel ways to game the system, even if we would prefer that innovation be directed toward advancing quantum computing.

Telemetry Dashboard

We announced a cost-effective telemetry solution that all validators would be able to participate in. The dashboard will surface key miner metrics including maximum difficulty requested and solutions per 24-hour period, along with validator-side data such as circuits generated, circuits verified, and heartbeat information. For miners, this means being able to see how the competition is performing -- not just relative rankings, but the underlying activity driving those rankings. The telemetry UI was built on top of Open Quantum infrastructure and will ship with the Shor's branch, viewable on the qBitTensor Labs website.

Shor's Challenge Launch

The Shor's branch went public in the repository ahead of a Monday, October 20th deployment. Miners were advised to review the branch and ensure their synapses are compatible before it goes live. The branch bundles the new Shor's challenge -- based on Peter Shor's 1994 factoring algorithm that ignited the quantum computing investment wave -- along with the telemetry system and some adjustments aimed at the circuit generation timing issue. For this initial version, validators generate the Shor's circuit and miners execute it faithfully, with verification on the backend. We signaled that even bigger plans for the Shor's challenge space would come with Phase 2 of Subnet 63.

Phase 2 Prize-Pool Economics for Subnet 63

We laid out the emerging design for Phase 2 of Subnet 63, which restructures miner emissions into three tiers of prize pools. The operational pool provides a steady reward to whoever holds the top spot on a given challenge. Milestone pools accumulate emission and unlock when miners achieve defined incremental accomplishments, with estimated payouts in the $10,000 to $50,000 range. Grand prize pools target breakthroughs believed to be possible but not yet achieved, with potential awards from $100,000 to $1 million depending on subnet performance. Once all pools are full, excess emission gets burned. We increased the share of emission reserved for these pools from 10% to 15% and will continue ramping it up as we approach the transition, which is designed to reduce miner sell pressure and attract significant attention from media and the broader industry.

Open Quantum Q4 Release Plan and Community Engagement

We shared that Open Quantum is firmly on track for a Q4 launch across three stages: a private release with hand-selected users and real QPUs running on Bittensor, a beta release through an integration partner's community, and finally a full public release with traditional marketing and media coverage. The subnet code has moved to end-to-end testing, the Python library supports circuit execution, and the website now has API key management and account management integrated. On the community side, we recapped recent quantum events including hosting the Iterate on AI conference in Boulder and sponsoring a quantum hackathon in South Carolina, with upcoming appearances at Chicago Quantum Summit, QEDC in New York, and Q2B Silicon Valley in December. We also acknowledged community feedback that our social media presence had been too quiet and committed to increasing the cadence of updates beyond the biweekly live broadcasts.
