qBitTensor Labs Live — July 2, 2026

July 2, 20261:22:00

One month into Enigma's launch and nearly a year into qBitTensor Labs. Breaking RSA races from 360 to 480 bits -- a 460-bit key cracked in 3.9 hours with a GPU number-field sieve -- while Hardening Quantum Proof miners build on each other's solutions. Web submissions move to an Open Quantum compute-credit model, PennyLane lands on SN48, QuEra claims fault tolerance by 2028 out of Quantum.Tech Boston, and a wave of Bittensor emission changes reshapes the network.

The July 2nd broadcast landed one month after Enigma went live and just shy of qBitTensor Labs' first birthday. ShorShot sat this one out on well-earned shore leave, leaving Bob and Omar to cover a packed agenda: a month of live competition on Enigma, the RSA challenge racing from 360 to nearly 500 bits, a new compute-credit path to web submissions, PennyLane support on SN48, a Quantum.Tech World recap out of Boston, and a wave of Bittensor emission changes reshaping the whole network.

Enigma: One Month In

The launch held up. No fundamental flaws, no showstoppers, nothing that needed a rethink. The surprises were smaller: far fewer validators participated than expected -- the team runs its own validator on an RTX 6000, with Rizzo running another, while many validators simply delegate back to the team to run. A single vulnerability surfaced in one challenge's scratch space, but the community reported it and it was patched before anyone exploited it. Notably, no one submitted the exploit to try to win -- they flagged it instead.

Breaking RSA -- 360 to 480 Bits in Weeks

  • Milestone 1 opened at 360-bit RSA -- hard enough not to fall instantly, but achievable with classical methods. Solved, as expected.
  • Milestone 2 jumped a full 100 bits to 460, which surprised even the team. It was cracked in 3.9 hours, just under the 4-hour wall time.
  • Milestone 3 steps up only 20 bits (480) -- but because RSA is exponentially hard, that "small" jump is a big one. Mid-stream, Omar broke the news that a 480-bit submission had just entered review.
  • Submissions cost 0.1 TAO each; roughly 137 came in total. The constrained environment (a single node, four hours) is deliberate: solve it small here, then hand the methods to researchers with supercomputers and months of time.

Inside the RSA-460 Solution

Omar walked through the winning 460-bit solution: a GPU lattice siever built on the General Number Field Sieve -- the same core method used to factor the largest RSA key ever broken (829-bit). The standout was memory discipline: an anonymous memfd kept temporary storage to roughly 100–200 MB, well inside the challenge's limits, answering earlier complaints that the environment didn't allocate enough scratch space. Run on supercomputers for months, the same approach could push past today's records.

Hardening Quantum Proof -- Standing on Shoulders

Peaked circuits are hard because they pack information into matrices too large to simulate on a classical computer. Milestone 1 fell to an MPS (matrix product state) simulator paired with canonical beam search -- an AI search technique -- with results validated across bond dimensions and by scrambling the qubit order to rule out lucky guesses. Milestone 2 built directly on it, adding an "unswap" technique that rearranges qubits to shed bond dimension without destroying the peak. The milestone-2 code even carried comments crediting the milestone-1 solution. That is exactly the virtuous cycle Enigma was designed to create: miners not just competing, but building on each other's work.

Web Submissions & Compute Credits

Today, participating in Enigma's challenges means registering a Bittensor miner and paying in crypto. The team has the infrastructure for web submissions but hit a wall: Stripe -- and the mainstream processors that mirror its terms -- won't touch contests that charge an entry fee for cash prizes. The fix reframes the payment as compute, not entry: users will link an Open Quantum account, purchase compute credits, and spend them to submit through the web portal. It keeps the experience clean and compliant, and it creates real subnet-on-subnet synergy -- Enigma participants become Open Quantum users, ahead of the roadmap where Quantum Compute (SN48) supplies the quantum resources Enigma's future challenges will run against.

Future challenges already in development: quantum RSA (real QPUs, necessarily small numbers in the NISQ era), quantum-simulation RSA (optimizing Shor's algorithm in a simulated environment), and ECC / post-quantum breaking to pressure-test crypto agility as the world migrates off RSA.

SN48: PennyLane, Docs, and a New Machine

Quantum Compute added full PennyLane support (Xanadu's framework) alongside existing Qiskit support -- often a single-line change, with no plugin import required if the package is installed -- riding PennyLane's momentum as it erodes Qiskit's once-dominant market share. The team shipped a complete documentation revamp, teased a new quantum computer coming exclusively through an Open Quantum partnership, and previewed a second partnership set to put Open Quantum in front of more than 20,000 quantum users.

Quantum.Tech World -- Boston

A busy show, and a well-attended one. Peter Shor wore an Open Quantum / Quantum Rings lanyard on stage. There was heavy federal presence (DOD, NSA, Department of Commerce), and copycats are starting to appear -- which, as Bob framed it, validates the category more than it threatens it. Two executive orders dropped: one pulling the post-quantum migration deadline forward to before the end of 2031, another funding quantum infrastructure and directing the government to procure a research-grade system by 2028. QuEra announced a five-year roadmap claiming fault-tolerant quantum computing by 2028 -- 256 logical qubits on AWS Braket at a 10⁻⁶ error rate.

Bittensor Shifts: Emissions, Root Reborn, Conviction

The pendulum swung back toward pro-innovation policy, fast:

  • Root Reborn -- routing idle root APY into subnets, ETF-style. Bob likes the concept (put your stake where your conviction is) but not the clunky implementation.
  • Price-based emissions replacing the unsustainable flow-based model, with mechanics that support young subnets while guarding against pump-and-dump.
  • Manual emission shutdown -- Const ending "free launch" for dormant or exploitative subnets, prompting a scramble among owners who had been quietly collecting emission.
  • Conviction and takeovers -- activated overnight. Bob's take: in an ecosystem that can rewrite how all capital flows in a single pull request, locking capital for a year mostly makes sense for operators who need to buy trust rather than earn it.

Community & What's Next

Sentiment ran strongly positive -- miners calling Enigma a great, straightforward experience, and others (rightly) calling the challenges hard. Terra Quantum's Taylor Hartley emailed to say she'd be talking up the RSA challenge at a major cybersecurity conference and invited the team along. On prizes: the earlier "$1M in prize pools by end of summer" projection is being walked back given TAO price swings, with a transparent update to follow. Next stop is the Exploit conference, where the team hopes to host a quantum fireside chat on what's real and what's hype.
