Live from Q2B Silicon Valley — Open Quantum credit system revamp, wallet linking with monthly Spark credit dividends, Qiskit and Penny Lane integration plans, MIT Quantum Hackathon announcement, and market outlook ahead of the halving.

We broadcast this episode live from our booth at Q2B, one of the premier quantum shows of the season in Silicon Valley. Between cleaning crews and leftover beer cans from the night before, we packed in a lot of ground to cover.

Open Quantum Credit System Revamp

We originally set out to make unlimited quantum compute free, funded entirely by miner emissions. With TauFlow changing the dynamics, we needed to rethink that approach to avoid constant sell pressure. We launched a revamped credit system where anyone can sign up for a free account and claim credits. We only give away credits where we know we have the budget from TauFlow to support it, which keeps the tokenomics solid whether emissions are high or in a trough.

We split credits into two types. Spark credits have a shorter lifetime (three months), are available through promotions and wallet linking, and can be used for public jobs executed through the Bittensor network. Full credits are paid, expire after a year, and unlock both public and private execution paths.

Wallet Linking and User Incentives

Wallet linking is now live. If you hold alpha in Subnet 63 or Subnet 48, you can link your wallet through the My Account page on Open Quantum. The verification process integrates with both the browser wallet and the CLI. Once linked, your subnet ownership translates into a monthly dividend of Spark credits based on the amount of alpha you hold.

Ecosystem Development and Future Plans

We are live with Qiskit, which represents about 74% of the quantum framework market share. Penny Lane is next, covering roughly the low teens to 20%. After that, Cirq rounds out the long tail. We are also working with QBraid and several new partners on native integrations where users get single-click account linking, rolling out in Q1.

Over the next 60 days, we plan to bring on one ecosystem partner, add one or more QPUs, ship Penny Lane support, and drive adoption through marketing initiatives. In Q1, we will add two more QPU vendors, sponsor the MIT iQWAC Quantum Hackathon, sponsor the APS March Meeting in Denver, pursue co-marketing with QPU partners, and begin Subnet 63 integration into Open Quantum. We are also working to line up institutional OTC buyers for miner emissions to further eliminate systemic sell pressure.

Subnet 63 Phase Two

We presented a plan to the validators for running the challenge system more on-network. Researchers discover challenges online, access existing source code, and submit solutions through CLIs or the website. Open Quantum prepares their submissions and manages miners on their behalf so researchers never have to deal with Bittensor complexity. Validators run the submitted source code, and solutions that pass go through a human review to ensure genuine quantum IP is being built. Prize pools are funded by emissions routed to treasury wallets, and winners are paid out in USD.

We have three big names in the quantum space interested in collaborating on challenges, one big name in crypto, and a couple of smaller players at the intersection of both. Phase two will be a Q1 activity.

Addressing Market Concerns

The halving is coming, and there is caution in the market. We see virtually zero near-term downside for our subnets. Subnet 48 is already burning 90% of emissions and only using 10%, so even cutting emissions in half barely moves the needle if we adjust our dials. On Subnet 63, all emissions fill treasury pools, so prize pools just build at whatever rate emissions come in. TAU becoming more deflationary should, in theory, make it a safer investment long-term.

Quantum Industry Highlights from Q2B

  • Joe Altepeter (DARPA) shared that in 2025, resource requirements for breaking RSA 2048 came down massively, requiring substantially fewer computational qubits than originally thought. He also noted surprise at how many viable quantum approaches have continued through the Quantum Benchmarking Initiative with substantial DARPA funding.
  • John Preskill discussed the same RSA-breaking innovations, reinforcing the significance of these advances.
  • Scott Aaronson talked about peaked circuits, noting that the experiments would not have been possible with hardware even two or three years ago. We met with Scott and shared the work our community has been doing on peaked circuits. He was particularly interested in whether people were simulating at scale or finding structural exploits.
  • Edward Farhi, a principal scientist at Google and co-inventor of QAOA, discussed opportunities for integrating larger-scale optimizations into the 300-to-500 qubit range.
  • Yuval Boger (QuEra) said he believes utility-scale quantum computers are sooner than five years away.

We continue to see that every organization purchasing physical quantum computers has unused capacity, which makes us extremely bullish about aggregating that into Open Quantum.
