The emergence of quantum computing presents both revolutionary potential and existential risks—especially for blockchain networks built on classical cryptographic assumptions. As quantum machines inch closer to practical reality, a quiet but critical project has entered the scene: Project Eleven. Designed not for hype, yield farming, or token launches, this initiative focuses on a long-overlooked vulnerability—quantum threats to Bitcoin and digital asset security.
At its core, Project Eleven aims to future-proof Bitcoin ownership by integrating post-quantum cryptography (PQC) into existing protocols without altering the underlying blockchain. Its first public-facing tool, Yellowpages, offers a novel approach to securing Bitcoin holdings against quantum attacks—without requiring users to migrate assets or change how they interact with their wallets.
The Quantum Threat to Bitcoin
Bitcoin relies on elliptic curve cryptography (ECC) for digital signatures. While currently secure, ECC is vulnerable to Shor’s algorithm—a quantum computing technique capable of deriving private keys from public ones. If large-scale quantum computers become operational, millions of BTC stored in reused or exposed addresses could be at risk.
Estimates suggest over 6.2 million BTC—worth more than $648 billion as of early 2025—are potentially vulnerable due to static storage, lost recovery phrases, or use of older address formats. These funds represent low-hanging fruit for future quantum adversaries.

Project Eleven does not wait for catastrophe. Instead, it proactively builds defenses through interoperable, non-invasive security layers that coexist with current infrastructure.
Introducing Yellowpages: Post-Quantum Ownership Layer
Yellowpages is not a wallet, chain, or token. It's a protocol-level tool that enables Bitcoin holders to generate and register quantum-resistant key pairs linked to their existing BTC addresses. This creates a verifiable "ownership certificate" resilient to future quantum attacks.
How It Works
- Users generate a new post-quantum cryptographic key pair using PQC algorithms (e.g., CRYSTALS-Dilithium or SPHINCS+).
- The public key is cryptographically bound to an existing Bitcoin address off-chain.
- Ownership linkage is stored in a decentralized registry (the “yellow pages”), accessible via lightweight verification nodes.
- No asset movement is required—your BTC stays where it is.
- In the event of a quantum breach, rightful ownership can be proven using the registered PQC key.
This design ensures backward compatibility and avoids hard forks or network-wide upgrades. It’s a pragmatic solution for an urgent problem: securing legacy assets without disrupting current systems.
Why This Approach Matters
Most post-quantum proposals require overhauling consensus mechanisms or replacing wallets entirely—processes that face high coordination costs and resistance within conservative ecosystems like Bitcoin.
Project Eleven sidesteps these barriers by offering a plug-and-play security layer:
- No changes to Bitcoin’s codebase.
- No mandatory user behavior shifts.
- Scalable across other UTXO-based chains in the future.
Its philosophy aligns with Bitcoin’s ethos: minimal intervention, maximum security.

Frequently Asked Questions (FAQ)
Q: Can quantum computers already break Bitcoin encryption?
Not yet. Current quantum machines lack the qubit count and error correction needed to run Shor’s algorithm at scale. However, experts estimate that cryptographically relevant quantum computers (CRQCs) could emerge within 10–15 years—making preparation essential now.
Q: Do I need to move my Bitcoin to use Yellowpages?
No. One of Yellowpages’ key innovations is non-custodial integration. You keep your coins in place while registering a post-quantum key off-chain. This eliminates transfer risks and gas fees.
Q: Is Project Eleven launching a token?
As of mid-2025, there is no announced token, incentive program, or governance model. The team emphasizes technical development over speculation.
Q: How does Yellowpages prevent abuse or fake registrations?
Registration requires cryptographic proof linking the PQC public key to the owner’s existing BTC address. Third-party auditors and open verification processes help maintain integrity.
Q: Will this work with hardware wallets?
Yes—the system is designed to integrate with major wallet standards (e.g., BIP-39, BIP-44). Future updates may include direct support for Ledger, Trezor, and other cold storage solutions.

Final Thoughts: Preparing for the Inevitable
Quantum computing isn’t science fiction—it’s an engineering challenge with growing momentum. Waiting until quantum attacks are feasible will be too late. Project Eleven represents one of the few initiatives taking a preventive, protocol-first approach to safeguard digital wealth.
By decoupling security upgrades from network forks and user migration, it offers a realistic path forward—one that respects Bitcoin’s conservative upgrade culture while preparing it for an uncertain future.
