Does Bitcoin cryptography have backdoors?

Bitcoin uses secp256k1, which was not NSA-recommended (unlike P-256), but it shares the same quantum vulnerability. The backdoor is the fundamental mathematics—broken by Shors algorithm.

What cryptographic backdoors have been discovered?

Confirmed backdoors include Dual_EC_DRBG (NSA), weakened DES key sizes (NSA), and various compromised random number generators. Many more are suspected but unconfirmed.

Are there backdoors in Ethereum cryptography?

Ethereum uses secp256k1 like Bitcoin, plus BLS12-381 curves. While not backdoored in the traditional sense, both are completely broken by quantum computers running Shors algorithm.

🔓 Quantum Backdoors Exposed

Legacy Cryptography Was Never Safe

✅ Confirmed Cryptographic Backdoors

Dual_EC_DRBG (2006-2013)

NSA inserted backdoor into NIST random number generator standard. Used by RSA Security, OpenSSL, and countless applications.

Confirmed by Snowden docs

DES Key Size (1977)

NSA convinced IBM to reduce DES key from 64 to 56 bits, making it breakable by government.

Confirmed by declassified documents

Clipper Chip (1993)

NSA tried to mandate hardware with key escrow, allowing government decryption.

Failed but revealed intent

💥 The Ultimate Backdoor: Math Itself

Quantum Computing Breaks the Foundation

All elliptic curve cryptography has the same "backdoor"—Shor's algorithm.

It doesn't matter if there are secret weaknesses planted by intelligence agencies. Quantum computers break the mathematical foundation itself.

ECDSA (Bitcoin, Ethereum) — BROKEN
EdDSA (Monero, Cardano) — BROKEN
BLS signatures (Ethereum 2.0) — BROKEN
RSA (legacy systems) — BROKEN

₿ The secp256k1 Question

Bitcoin chose secp256k1 specifically because it was not NSA-recommended. Satoshi suspected NIST curves might be backdoored.

But it doesn't matter. Quantum computers don't need backdoors. They break the math directly.
