What makes Tidecoin quantum-resistant?

Tidecoin replaces Bitcoin's ECDSA with FALCON-512, a lattice-based digital signature scheme selected by NIST for standardization as FN-DSA (Draft FIPS 206). The underlying hard problem — Short Integer Solution over NTRU lattices — has no known efficient quantum algorithm. Every transaction since genesis (December 2020) uses post-quantum signatures.

Can I mine Tidecoin with a regular computer?

Yes. Tidecoin uses YespowerTIDE, a memory-hard proof-of-work algorithm designed for CPU mining. No specialized hardware (ASICs or GPUs) is required. You can mine from a desktop, laptop, Android phone, or even a web browser.

Is Tidecoin a Bitcoin fork?

Tidecoin is built on Bitcoin Core v30, preserving the UTXO model, scripting system, and 15+ years of peer-reviewed consensus logic. The key change: all classical cryptography (ECDSA, Schnorr, Taproot) was replaced with post-quantum primitives from NIST's PQC standardization process.

Was there a premine or ICO?

No. Tidecoin had no premine, no initial coin offering, and no developer allocation. All TDC in circulation were earned through proof-of-work mining from block zero.

CRYPTO VALUE EXPOSED TO Q-DAY

Quantum era is coming fast

Every Bitcoin wallet that has ever broadcast a transaction exposes its public key on-chain — permanently. A sufficiently large quantum computer running Shor's algorithm can derive the private key from it. Over $1.3 trillion in crypto is already vulnerable.

Tidecoin replaced ECDSA with NIST-standardized Falcon-512 at genesis in 2020 — five years before the rest of the industry started worrying.

// what makes tidecoin different

What makes Tidecoin different from other cryptocurrencies?

Six pillars — signatures, schemes, transport, wallet derivation, mining and foundation — all post-quantum from day one.

01 · Signatures

FALCON-512 Signatures

Lattice-based digital signatures selected by NIST for standardization as FN-DSA (Draft FIPS 206). 666-byte signatures with constant-time integer emulation — no floating-point side channels.

02 · Schemes

5 PQ Signature Schemes

Falcon-512/1024 (Draft FIPS 206) + ML-DSA-44/65/87 (FIPS 204, finalized). Multi-scheme agility: if one algorithm is compromised, alternatives activate via consensus upgrade.

03 · Transport

Quantum-Secure P2P

ML-KEM-512 (NIST FIPS 203) replaces X25519 key exchange. Every node-to-node connection uses post-quantum encrypted transport, enabled by default.

04 · Wallet

PQHD Wallet

Post-Quantum Hierarchical Deterministic wallet replaces BIP-32. Hardened-only derivation with SHA-512 KDF. Multi-seed, multi-scheme, encrypted storage.

05 · Mining

CPU Mining

YespowerTIDE memory-hard algorithm (N=2048, r=8). Mine from any computer, phone, or browser. No ASICs, no GPU farms. Fair distribution.

06 · Core

Bitcoin Core v30

Not a new chain — 15+ years of battle-tested Bitcoin consensus logic. UTXO model, scripting system, peer-to-peer network. Only the classical cryptography was replaced.
