Tidecoin

Secure the centuries. Post-quantum, decentralized money.

[Tidecoin @tidecoin]

The crypto industry is waking up to post-quantum safety.

We never slept.

Falcon is not affected.

Tidecoin lore hits different now.

In 2020, the idea was simple:

When the quantum threat became real, there should already be a Bitcoin-like supply of quantum-resistant coins in the wild.

Not launched after the panic.
Not migrated during the panic.
Already mined.

BTC: ~20M issued.
TDC: ~18.8M issued.

The clock was the thesis.

Falcon is the quiet part of post-quantum crypto.

Not the loudest signature scheme.
The compact one.

Falcon-512: 666-byte signatures.
NTRU lattices. NIST-selected. Built for chains where every byte lives forever.

Most blockchains still need a migration story.
Tidecoin doesn’t.

Genesis: December 27, 2020.
Falcon from block zero.

[Tidecoin @tidecoin]

Tidecoin genesis: December 27, 2020.

Coinbase message literally quoted the first photonic quantum supremacy paper: Jiuzhang.

Not a roadmap. A timestamp.

About 1 in 3 BTC is already sitting behind exposed public keys.

Post-quantum addresses don’t save a chain retroactively. Old coins still have to migrate.

Harvest today. Decrypt tomorrow.

Tidecoin started on the other side.

@ourcryptotalk Tidecoin: Live, Fully PQ since genesis, running Falcon since December, 2020

[Tidecoin @tidecoin]

@al_goanna yeah, probably. Running Falcon before algorand even thought about it.

[Tidecoin @tidecoin]

@QuantusNetwork Yep. Any day any time.

[Tidecoin @tidecoin]

@solana Full details in our Whitepaper (v2.0):

[Tidecoin @tidecoin]

While @solana just chose Falcon for post-quantum security…

Tidecoin has been running Falcon 512 natively from genesis since Dec 27, 2020.

✅ 5+ years live
✅ 2.3M+ blocks secured
✅ Zero incidents
✅ Smallest PK+sig (~1,563 bytes)
✅ NIST Category 1 quantum resistance

[Tidecoin @tidecoin]

@KayBlockchain At tidecoin - we are running Falcon-512 post-quantum safe from GENESIS (no migration necessary) since December 27, 2020 - OVER 5 YEARS. Over 2,500,000 blocks secured.

Falcon is a good choice.

[Tidecoin @tidecoin]

@adajonuse @solana Definitely. Falcon is a good choice.

[Tidecoin @tidecoin]

@quantum_safe Ride the TIDE with Post-Quantum Safe Tidecoin.

[Tidecoin @tidecoin]

@YuviLightman @bmartins_ @AlgoNumbers It is a problem that is very solvable. We are implementing pqhd wallet standard.
