On January 14, 2026, Project Eleven, a post-quantum security startup, announced it has raised $20 million in a Series A funding round. The round, led by Castle Island Ventures, brings the company's valuation to $120 million.
​The Funding Details
​The Series A saw significant participation from high-profile crypto and venture firms, including:
​Lead Investor: Castle Island Ventures (with General Partner Nic Carter joining the board).
​Participants: Coinbase Ventures, Fin Capital, Variant, Quantonation, Nebular, Formation, Lattice Fund, Satstreet Ventures, Nascent Ventures, and angel investor Balaji Srinivasan.
​Total Capital: This round follows a $6 million seed round in 2025, bringing the company’s total funding to $26 million.
​The Mission: Defeating "Q-Day"
​Project Eleven is focused on the "eleventh hour" threat posed by quantum computing to existing blockchain infrastructure. Most current digital assets rely on Elliptic Curve Cryptography (ECC), which could theoretically be broken by a sufficiently powerful quantum computer (an event often called "Q-Day").
​The company is building tools to help decentralized networks and financial institutions navigate the multi-year migration to Post-Quantum Cryptography (PQC). Key initiatives include:
​Yellowpages: A live application that allows Bitcoin holders to generate post-quantum keys, serving as a "commitment" to future migration and proof of ownership.
​Solana Partnership: The firm recently collaborated with the Solana Foundation to develop a post-quantum testnet and conduct a full-scale threat assessment.
​Migration Tooling: Developing readiness assessments, migration test environments, and deployment sequencing to ensure networks don't have to "improvise under pressure."
​What’s Next?
​Led by CEO Alex Pruden (formerly of Aleo and a16z), Project Eleven plans to use the new capital to expand its product suite in early 2026.
This expansion will focus on providing institutional-grade tools for protocols and end-users to future-proof their digital assets before quantum breakthroughs become a reality.

Bitcoin's "quantum death sentence" refers to the potential future scenario where sufficiently advanced quantum computers could use Shor's algorithm to break the underlying elliptic curve cryptography (ECC) that secures Bitcoin transactions. This would allow attackers to potentially steal funds from vulnerable addresses by deriving private keys from exposed public keys.
The "fix already hidden in the code" refers to current built-in Bitcoin features and ongoing development efforts for a coordinated transition to post-quantum cryptography, such as using hash-based address formats and planned soft forks.
Wall Street Rift
Jefferies, represented by Christopher Wood, recently eliminated its Bitcoin exposure, citing the existential threat of quantum computing as a disqualifying factor for long-term, pension-style capital, arguing that a hedge requiring a contentious protocol upgrade is not the same as physical gold.
ARK Invest, represented by Cathie Wood, counters this by urging investors to focus on Bitcoin's lack of correlation with traditional markets, viewing it as an evolving asset that can adapt to future challenges. They argue that traditional finance may face greater near-term peril from quantum threats.
Key Insights
Vulnerability: The primary risk lies with older or reused "pay-to-public-key" (P2PK) addresses, where the public key is permanently exposed on the blockchain. An estimated 4 million to 6.5 million BTC are held in such vulnerable addresses.
Mitigation Measures in the Code:
P2PKH (Pay-To-Public-Key-Hash) addresses offer partial protection because the public key is only revealed during a transaction, creating a narrow window of vulnerability (around 10 minutes for a transaction to be mined).
Taproot (P2TR) addresses are also more quantum-resistant and designed to be compatible with future upgrades.
Developer Proposals: Active proposals, like the one by developer Hunter Beast, exist to introduce a quantum-resistant public key system via a soft fork, which would require users to move funds to new, secure addresses.
The Path Forward
The long-term solution involves migrating the entire network to new post-quantum cryptography (PQC) standards, likely through a soft fork. The challenge lies in achieving global consensus within the decentralized Bitcoin community and the significant increase in transaction data size that PQC algorithms currently entail.
While experts agree a sufficiently powerful quantum computer is likely years, if not decades, away, the time to prepare is now, as coordination and implementation of an upgrade will take time.

The "Digital Gold" narrative is facing its most technical challenge yet. Today, RotationRadar is tracking a major institutional shift: Jefferies’ global strategist Christopher Wood has officially removed Bitcoin from his flagship "Greed & Fear" portfolio.
After a staggering 325% gain since his initial allocation in late 2020, Wood is hitting the exit button. But this isn't about market volatility or "fud" cycles—it’s about Quantum Computing.

The Strategy Shift: Gold Reclaims the Throne
Jefferies has completely liquidated its 10% Bitcoin allocation. The capital didn't go to cash or AI stocks; it went straight back to the "Old Guard":
* 5% into Physical Gold
* 5% into Gold Mining Stocks
> The Rationale: While Wood admits the quantum threat isn't an "immediate" price killer, he argues that for pension-style, long-term portfolios, Bitcoin’s foundation as a "Store of Value" is no longer mathematically certain.
The Technical Threat: Shor’s Algorithm & 2026-2027
The concern centers on the speed of quantum hardware. Reports suggest we are entering a "critical window" where quantum computers could utilize Shor’s Algorithm to reverse-engineer private keys from public keys.
The Vulnerability Data:
* Circulating Risk: Estimates from Chaincode Labs suggest that 4 to 10 million BTC (roughly 20-50% of the supply) are held in addresses vulnerable to quantum extraction.
* The "Legacy" Problem: This includes "lost" Satoshi-era coins and institutional wallets that have reused addresses, exposing their public keys on-chain.
* The Timeline: While many expected this threat in the 2030s, recent breakthroughs in error correction have pulled the "Q-Day" risk forward to the 2026-2027 horizon.
Is it Over for Bitcoin?
Not according to the developers. The Bitcoin community is already discussing "Post-Quantum Cryptography" (PQC) soft forks. However, the transition is complex:
* The "Burn" Dilemma: Should the network "burn" or lock up old, non-migrated coins to prevent a quantum thief from crashing the market?
* The "Collect Now, Decrypt Later" Attack: Bad actors may already be harvesting encrypted data today, waiting for the hardware to catch up.
RotationRadar’s Take 🔍
For RotationRadar, this move by Jefferies signals a shift in institutional risk assessment. If Bitcoin is "Digital Gold," it must prove it is immutable against any technology. Until a quantum-resistant upgrade is live, we may see more "old money" hedge back into physical bullion.
What’s your move?
Are you holding through the "Quantum Winter" or rotating into gold like the big banks?

The recent decline may be due to the mention by Coinbase's research director David Duong of "33% $BTC of Bitcoin supply facing quantum risk", leading to some fluctuations in the market.
However, after carefully studying the logic of the report and combining it with market feedback, I believe this is more like an industry risk warning report rather than an immediate disaster forecast. In other words, this is just a 'gray rhino', not a 'black swan'.
The crypto market is extremely sensitive to real crises. If the risk of 6,500,000 BTC is a fact that is 'imminent', what we are seeing is certainly not the slight adjustments of a few points like now. The current trend in the market clearly tells us: this is just a long-term technical alert, not an immediate selling signal.
