Quantum threat pushes Bitcoin to 2030 deadline
Summary
- $50M consortium forms to harden Bitcoin against quantum attacks by 2030.
- RSA encryption is already being harvested for future decryption.
- LLMs now verify Bitcoin’s code, but quantum forces a race.
Quantum computing is no longer theoretical. On July 24, 2026, Kazu Nakashigi of Yakumo declared that RSA encryption will fall within five to ten years. His warning wasn’t speculative - it was a timeline. With 6,000 physical qubits already demonstrated and algorithmic advances slashing the threshold for utility to 10,000, the convergence is imminent.
The threat isn’t future - it’s present. Hostile actors are already harvesting encrypted data in a 'harvest now, decrypt later' strategy. According to Nakashigi on Rabbit Hole Recap, governments and financial institutions are vulnerable today because their secrets will be exposed once quantum processors mature by 2030.
In response, nine major financial players - including BlackRock, Fidelity, and Coinbase - pledged $50 million to fund quantum-resistant Bitcoin research. Mike Schmidt of Brink will coordinate the Bitcoin Security Consortium, designed to fund open-source developers without centralizing control. But skepticism remains: Matt Odell warns this could become a backdoor for institutional influence.
"They are storing encrypted files today to crack them when the hardware arrives."
- Kazu Nakashigi, Rabbit Hole Recap
Meanwhile, Bitcoin’s core developers are already ahead on verification. Keegan’s BTC Verified project, covered in Bitcoin Optech on July 21, uses LLMs as 'chainsaws' to automate formal proofs in Lean 4. This compounding proof capital ensures Bitcoin’s math is not just tested - but proven. But as Andrew noted, even well-intentioned optimizations can backfire: a LevelDB tweak once caused nodes to rewrite 15GB hourly due to unpredictable IO patterns.
The hardware race is accelerating. While IBM and Google stick with expensive superconducting qubits, Yakumo’s neutral atom approach - using lasers and vacuum systems - promises 100x lower costs. Nakashigi compares it to Toyota’s integrator model: they don’t make every part, but they design the system.
"The industry joke that quantum is always a decade away is finally losing its teeth."
- Kazu Nakashigi, This Week in Startups
The clock is set. By 2030, quantum utility arrives. Bitcoin must adapt before the first RSA breach makes legacy encryption obsolete. The funding, the tools, and the threat are all real. The race isn’t just technological - it’s existential.

Why quantum has been "10 years away" for 30 years | E2316 • Jul 24
- Kazu Nakashigi's company, Yakumo, builds quantum computer hardware, specifically Quantum Processing Units (QPUs), which are difficult to create and require many units for useful calculations.
- Kazu Nakashigi notes that quantum computing has been '5 to 10 years away' for 30 years primarily due to hardware challenges, making it hard to create special corrugated units (QPUs).
- Kazu Nakashigi clarifies a misconception: quantum computers are not universally faster than CPUs or GPUs, but are applied to specific difficult problems like combinations or RSA cryptography.
- The required number of qubits for practical quantum computing has significantly decreased from one million to approximately 10,000, while physical qubit counts have increased from 1-10 to 6,000.
- Kazu Nakashigi predicts that the necessary and achievable qubit counts will converge around 2030, enabling more widespread real-world applications of quantum computers in data centers, with some already installed in Japan by companies like Toyota.
- Quantum calculations currently make many errors, requiring 'quantum error corrections' (QEC) to protect qubit information and build scalable, robust systems; Kazu Nakashigi likens this challenge to the early days of classical computers in the 1980s.
- Yakumo employs a neutral atoms methodology for quantum computing, which differs from Google and IBM's superconducting qubits (requiring extreme cooling) or other methods using ions or photons.
- Yakumo grew to nearly 70 employees within 15 months of its April 2025 launch, with 20-30% of its tech staff being non-Japanese, including two of three division heads, leveraging Kyoto's beauty and Kyoto University's deep research background in neutral atoms.
- Yakumo aims to be a 'Toyota of quantum computers,' focusing on assembling a full-stack system from specialized components like high-fidelity lasers from Hamamatsu Photonics (Japan) and Nic Photonics (Denmark), rather than building every part.
- AI significantly impacts quantum computing, particularly for 'AI for quantum' applications where classical computers and AI/LLMs are used to estimate and correct errors in quantum calculations.
- 'Quantum for AI' is a future prospect where unique data generated by quantum computers, such as from fluid dynamics calculations, could make AI models smarter, though practical examples are not yet available.
- Quantum computers are significantly less power-hungry than classical computers; for certain problems with 40-50 qubits, quantum machines can consume less energy, potentially aiding CO2 reduction.
- Kazu Nakashigi believes quantum computers will function as accelerators in hybrid systems alongside classical computers, sharing workloads to make the overall computing environment smarter, rather than fully replacing existing systems.
- Kazu Nakashigi suggests that RSA cryptography could be broken by quantum computers within the next 5 to 10 years, warning that encrypted data collected now could be decrypted later, posing a national security risk.
- The US government aims for a 'very useful computer' by 2028, reflecting aggressive competition in quantum computing among leading nations like China, the United States, EU, and Japan, which do not fully share their scientific progress.
- Karthik highlights the high current cost of quantum computing, with Toshiba's SQBM costing $90/hour and IBM's service costing $3,000/hour.
- Kazu Nakashigi claims Yakumo's neutral atom approach could be 100-1000 times cheaper per qubit than superconducting qubits, which can cost up to $1 million per physical qubit.

Bitcoin Optech: Newsletter #414 Recap • Jul 21
- Keegan's BTC Verified project aims to apply formal verification using Lean 4 to the Bitcoin protocol, building a living body of knowledge to crystallize understanding and evaluate changes.
- Keegan notes that while proof assistants like Lean 4 are not designed for efficient execution, they are crucial for high-stakes projects where cost of failure is extremely high, such as the Bitcoin protocol.
- Andrew reports that Bitcoin Core releases 29.4, 30.3, and 31.1 fix a long-standing LevelDB bug that caused excessive disk I/O from repeated chain state compactions.
- The LevelDB bug worsened in Bitcoin Core 29 due to increasing the default file size from 2 MB to 32 MB, leading to 15 GB of read/write I/O per compaction; this was exacerbated in version 30 by hourly chain state flushes.
- The primary cause of the LevelDB issue was the 'seek compaction' feature, which prematurely compacted files after frequent reads, even if they were not full; the fix involved disabling this feature.
- Andrew's PR 35295 significantly speeds up Initial Block Download (IBD) and steady-state block validation by parallelizing UTXO lookups from disk using worker threads, preventing the validation thread from waiting on single reads.
- Andrew's IBD optimization makes systems at least 50% faster, with network-connected storage like AWS seeing up to three times faster IBD, and typical performance gains around 35% on standard hardware.
- Bitcoin Core 35209, included in recent maintenance releases, provides a cleaner fix for CVE-2024-52911, addressing a vulnerability that could cause a remote crash by accessing freed memory during specially crafted block validation.
- Andrew's PR 35568 disables bloom filters in the TXO Spender Index, saving disk space and time because the index's iterator-based lookup pattern does not benefit from bloom filters designed for point reads.
- Bitcoin Core PR 34897 prevents index inconsistencies during unclear shutdowns by ensuring indexes like CoinStats never get ahead of the chain state's last durable UTXO flush.
- Bitcoin Core PR 35406 adds a limit of 10,000 transactions to the tracking queue for private broadcast, preventing resource exhaustion if transactions are not relayed due to policy differences or poor connectivity.

361 | Bonnie Bassler on How Bacteria Talk and Work Together • Jul 20
Also from this episode: (18)
Physics (1)
- Sean Carroll's third book in "The Biggest Ideas in the Universe" series, titled "Complexity and Emergence," has been submitted to his publisher, though the release date remains uncertain.
Biology (16)
- The episode explores self-organization and complexity in biological systems, using the concept of 'more is different' coined by physicist Philip Anderson to describe emergent collective behavior from individual units.
- Bonnie Bassler's interest in bacteria stemmed from an accidental undergraduate lab placement, where she found them to be a fantastic model system for rapid experimentation and understanding fundamental biological questions.
- Bacteria, ancient and single-celled organisms, have been on Earth for billions of years, possessing only a few thousand genes, and were initially considered asocial recluses until the discovery of quorum sensing.
- Quorum sensing is a bacterial communication process where individual cells produce and release chemical signal molecules, which accumulate in proportion to cell density.
- When signal molecules reach a threshold concentration, bacteria infer the presence of neighbors and synchronously alter gene expression to perform collective behaviors, which they could not achieve individually.
- Bacterial communication is multilingual; some signals are species-specific, others are family-specific, and a universal signal indicates the presence of 'other' bacteria, allowing them to measure ratios and adapt behavior.
- Quorum sensing controls group behaviors like virulence (pathogenesis), production of beneficial 'public goods' such as vitamins, and formation of resilient biofilms on nearly every surface on Earth.
- The human body harbors at least as many bacterial cells as human cells, containing 100 times more bacterial genes than human genes, and accounting for about five pounds of body weight.
- The microbiome is crucial for human health, providing enzymes to digest plant food, occupying real estate against pathogens, and potentially influencing personalized medicine outcomes by affecting drug metabolism.
- Quorum sensing evolved from simple, cheap metabolic byproducts that leaked from cells, later co-opted by evolution to become signals, with the ability to detect them spreading throughout the bacterial kingdom.
- Bioluminescence, where marine bacteria emit blue light collectively, was the founding example of quorum sensing discovered by Woody Hastings in the 1970s, making an invisible bacterial behavior measurable.
- Bacterial quorum sensing can control programmed cell death in biofilms, where older cells die regionally to release nutrients, potentially aiding the survival of younger community members during lean times.
- Cross-domain communication in quorum sensing shows that human gut cells produce quorum-sensing mimics to influence bacterial behavior, and bacterial viruses (phages) eavesdrop on bacterial signals.
- Phages use bacterial quorum sensing signals to decide between a dormant (lysogenic) or host-killing (lytic) life cycle, only opting for the lytic mode when high host cell density ensures new infections.
- The principles of quorum sensing could be leveraged for medical and industrial applications, such as developing antagonists to disrupt pathogenic bacterial communication or enhancing beneficial bacterial activities.
- While quorum sensing demonstrates coordinated collective behavior, Bonnie Bassler argues it is not true multicellularity because individual bacterial cells can still survive independently, unlike specialized cells in complex organisms.

Rebuilding the $12T Repo Market on Bitcoin | Bitcoin Dave • Jul 20
- Dave Ruff argues Bitcoin is "primal" collateral for the $12T repo market, offering zero counterparty risk and minute-level settlement compared to slow, trust-based Treasuries.
- Dave Ruff claims moving repo to Bitcoin shifts the system from creditworthiness and institutional trust to verifiable possession, relying on cryptographic math for liquidity.
- Dave Ruff contends that the "pristine" nature of US Treasuries is an illusion, sustained by central banks. Bitcoin offers a hard-capped, non-sovereign alternative as debt levels become unsustainable.
- Dave Ruff sees Bitcoin transitioning from a speculative asset to the bedrock of institutional lending and global credit, driven by the $12T market's need for harder assets.
- Dave Ruff highlights Discreet Log Contracts (DLCs) and Layer 2 solutions as crucial infrastructure for the global repo market. These tools enable automated liquidations and margin calls without intermediaries.
- The programmable layer solves the lending "hand-off" problem, instantly triggering liquidations if collateral value drops. This infrastructure effectively builds a decentralized version of the discount window.
