By introducing the Post-Quantum security signature algorithm, a decentralized currency system, Tidecoin, is designed.

The proof of power consensus and CPU friendly POW algorithm make Tidecoin achieving a breakthrough level in decentralization, and security.

The currency design enables Tidecoin to run on various types of ubiquitous computing devices, enabling pervasive process of value, even that in multiple worlds.

The operation of the Tidecoin network is based on mathematical proofs and physical laws.

We reviewed the experimental results of Bitcoin in the decentralized cash system, and clarified the core of it: decentralization, security, and scalability.

To this end, we have designed a cash system (Tidecoin) based on Post-Quantum security crypto algorithm.

The Tidecoin network is based on mathematical proof and physical laws, which ensures its decentralization and security nature. The script system scales the network by programmable code or sidechains.
