StackerZero
Zero reuse. Zero exposure. Zero trust.
Bitcoin defense intelligence for serious holders. We track quantum threats, BIP 360 progress, key hygiene, and every attack vector — so your stack survives what is coming.

Threat Matrix
Every vector that threatens your Bitcoin. Know the enemy.
Quantum Computing
Shor's algorithm can derive private keys from exposed public keys. ~4,000 logical qubits needed. Google officially moved Q-Day to 2029. Migrate now.
Address Reuse
Spending from an address exposes your public key on-chain. Any reused address is permanently vulnerable to future quantum attacks.
Custodial Risk
Exchanges hold your keys. Hacks, insolvency, and regulatory seizure can wipe your holdings overnight. Not your keys, not your Bitcoin.
Seed Exposure
Digital seed phrase copies (photos, cloud, email) are catastrophic. Single-location backups are single points of failure.
Supply Chain Attack
Tampered hardware wallets shipped pre-compromised. Always buy direct from manufacturers and verify firmware hashes.
Physical Coercion
The $5 wrench attack. If people know you hold Bitcoin, you become a target. OpSec and plausible deniability are essential.
Quantum Timeline
The race between quantum computing and Bitcoin cryptography.
The Quantum Event Horizon
The point where the quantum threat timeline crosses the Bitcoin upgrade timeline. Charles Edwards (March 2026): "We are closer to that horizon than most people realize." Your address hygiene today determines your exposure when that day comes.
Defense Guide
The playbook for protecting your Bitcoin at every layer.
Cold Storage Architecture
Address Auditor
Paste any Bitcoin address to instantly check its type, balance, and quantum exposure risk.
Stay Ahead
Get alerts when quantum milestones are reached, new Bitcoin vulnerabilities are discovered, or urgent OpSec threats emerge. No spam. Only signal.
The Quantum-Resistant Bitcoin Upgrade
BIP 360 introduces a new address type (bc1z) that commits to a Merkle tree of post-quantum spending conditions — making Bitcoin safe against Shor's algorithm.

How P2MR Works
A P2MR output commits to a Merkle root. Each leaf is a different quantum-resistant spending script. Only the chosen leaf is revealed at spend time.

Time Until Q-Day
Google estimates a cryptographically relevant quantum computer arrives by 2029. Your Bitcoin needs to migrate before then.
