Why Tidecoin?

Tidecoin is an upgrade of Bitcoin by replacing ecdsa cryptography signature algorithm with Post-Quantum security ones. The cryptography used by Tidecoin is falcon-512 which is one of NIST(National Institute of Standards and Technology)'s finalists for Post-Quantum security standards. This will make Tidecoin to keep on ensuring its security characteristics even faced with quantum computers.

Introduction

09/Dec/2020, "Photonic Quantum Computer Displays 'Supremacy' Over Supercomputers", a news from spectrum.ieee.org. It clearly shows that billions value on bitcoin network is facing the threat of Quantum computers. It is time to build a Post-Quantum security cryptocurrency. Tidecoin is an attempt to build a quantum secure cryptocurrency.

Tidecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Tidecoin is an open source global payment network, and fully decentralized without any central authorities. Features of Post-Quantum security make Tidecoin as a replacement to Bitcoin. Tidecoin's new cryptography algorithm of Falcon is an lattice-based cryptography algorithm and based on the theoretical framework of Gentry, Peikert and Vaikuntanathan. There is no efficient solving algorithm currently known in the general case, even with the help of quantum computers, because the underlying hard problem is the short integer solution problem (SIS) over NTRU lattices.
