The rise of quantum computing promises breakthroughs across industries—but it also introduces a silent, systemic threat to one of the digital age’s most valuable assets: cryptocurrency. At the heart of this vulnerability lies the cryptographic foundation of blockchains like Bitcoin. If left unaddressed, quantum computers could one day decrypt private keys from public addresses, potentially unlocking trillions in digital wealth. Enter Project Eleven, a forward-thinking initiative launched in 2024 to preempt this crisis by integrating Post-Quantum Cryptography (PQC) into existing blockchain ecosystems—starting with Bitcoin.
Unlike typical Web3 ventures chasing yield, liquidity mining, or modular scalability, Project Eleven focuses on a long-overlooked but critical challenge: future-proofing cryptographic security. Its mission is not to build a new chain or launch a token, but to deliver a modular, interoperable defense layer that protects assets without disrupting user experience or requiring protocol-level changes.

The Quantum Threat to Bitcoin and Crypto Assets
Bitcoin relies on elliptic curve cryptography (ECDSA) to secure transactions and verify ownership. While currently unbreakable by classical computers, this system is theoretically vulnerable to quantum attacks—especially Shor’s algorithm, which can derive private keys from public ones with sufficient quantum computing power.
Although large-scale, fault-tolerant quantum computers are still years away, the risk isn't hypothetical. A growing number of Bitcoin addresses contain funds that are potentially exposed due to reused addresses, inactive wallets, or weak key generation practices. According to Project Eleven’s data as of January 17, 2025, over 6,262,905 BTC—valued at more than $64.8 billion—reside in quantum-vulnerable addresses.
These "quantum-susceptible" holdings include:
- Long-dormant wallets from early adopters
- Addresses with publicly visible public keys (e.g., on blockchain explorers)
- Funds stored in non-upgraded legacy wallets
Once quantum computers reach sufficient maturity, these assets could be at risk of theft—even without user interaction.
Yellowpages: A Post-Quantum Identity Layer for Bitcoin
Project Eleven’s first public-facing product, Yellowpages, aims to address this threat by introducing a post-quantum ownership proof system without altering Bitcoin’s base protocol.
How Yellowpages Works
Yellowpages allows Bitcoin holders to generate PQC-secured key pairs (using lattice-based or hash-based cryptography) and cryptographically bind them to their existing BTC addresses off-chain. This binding creates a verifiable, future-proof identity layer that proves ownership—even if classical cryptography is compromised.
Key features:
- No asset migration required: Users keep their BTC on current addresses.
- No behavior change needed: No new wallets, seed phrases, or transaction patterns.
- Backward compatibility: Works with all existing Bitcoin infrastructure.
- On-demand verification: Ownership proofs can be triggered when needed (e.g., inheritance, audits).
This hybrid approach—combining on-chain data with off-chain cryptographic attestations—enables proactive defense while minimizing disruption.

This coalition underscores growing recognition that quantum resilience is not just a theoretical concern—it's an urgent infrastructure priority.
Development Progress and Security Audits
As of June 2025, Yellowpages has completed its prototype phase and entered internal protocol validation and baseline testing. The team is actively refining:
- Key registration workflows
- Cross-platform compatibility
- Zero-knowledge proof integrations (for privacy-preserving verification)
Security audits are being conducted by Cure53, a globally recognized cybersecurity firm with deep experience in cryptographic systems. Results are expected to be published publicly in Q3 2025.
Currently, Yellowpages is not live on Bitcoin mainnet, nor does it have public access portals. There are no plans announced for token issuance, governance models, or incentive programs.
Frequently Asked Questions (FAQ)
Q: Can quantum computers already break Bitcoin encryption?
A: Not yet. Current quantum computers lack the qubit stability and scale to run Shor’s algorithm effectively against ECDSA. However, experts estimate that within 10–15 years, such capability may exist—making early preparation critical.
Q: Do I need to move my Bitcoin to use Yellowpages?
A: No. Yellowpages does not require asset transfers. It adds an ownership verification layer using off-chain cryptographic binding to your existing address.
Q: Is Project Eleven building a new blockchain?
A: No. Project Eleven is not launching a chain. It develops plug-and-play security modules designed to integrate with existing protocols like Bitcoin.
Q: Will Yellowpages slow down transactions?
A: No impact on transaction speed. The system operates off-chain and only activates during ownership verification events.
Q: Are there any tokens or rewards associated with Project Eleven?
A: As of now, there is no token, staking mechanism, or incentive program. The project remains focused on research and deployment.
Q: How does Yellowpages handle privacy?
A: The protocol uses zero-knowledge techniques where possible to ensure verification occurs without exposing sensitive metadata. Full privacy specifications will be released with the audit report.

Final Thoughts: Preparing for the Inevitable
Quantum computing isn’t replacing blockchain—it’s challenging its assumptions. Projects like Project Eleven play a vital role in ensuring that the trillion-dollar crypto economy doesn’t become obsolete overnight.
By introducing pragmatic, non-invasive, and standards-aligned post-quantum solutions, Project Eleven offers more than technology—it offers peace of mind. For long-term holders, institutions, and protocol developers alike, preparing for quantum threats isn’t speculative. It’s responsible stewardship.
