[ANN] Tidecoin: Post-Quantum Security Coin | PoW only | CPU friendly algo

Tidecoin : A Post-Quantum Security Peer-to-peer Crypto Cash

By introducing the Post-Quantum security signature algorithm, a decentralized currency system Tidecoin  is designed. The operation of the Tidecoin  network is based on mathematical proofs and physical laws. 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.

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.


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.



Features:

• NIST's Post-Quantum security standard
• Symbol: TDC
• Total supply: 21000000
• Block time: 60 seconds
• PoW only, all coins are mined
• PoW Algorithm: yespower, CPU friendly algorithm, more inclusive
• Segwit supported, reduce block size largely
• Reward quartering time: exponential increase：0.5, 1, 2, 4, 8,... Years

Post-Quantum security signature algorithm
Falcon - Fast-Fourier Lattice-based Compact Signatures over NTRU. Falcon follows a framework introduced in 2008 by Gentry, Peikert, and Vaikuntanathan, the high-level idea is the following:

The public key is a long basis of a q-ary lattice. The private key is (essentially) a short basis of the same lattice. In the signing procedure, the signer:

• Generates a random value salt
• Computes a target c=H(msg||salt), where H is a hash function sending an input to a random-looking point (on the grid)
• Uses his knowledge of a short basis to compute a lattice point v close to the target c
• Outputs (salt, s), where s=c−v

In the verifying procedure, The verifier accepts the signature (salt, s)

• if and only if the vector s is short
• H(msg||salt) −s is a point on the lattice generated by his public key.

Falcon offers the following features:

Security: a true Gaussian sampler is used internally, which guarantees negligible leakage of information on the secret key up to a practically infinite number of signatures (more than 264). To give a point of comparison, Falcon-512 is roughly equivalent, in classical security terms, to RSA-2048, whose signatures and public keys use 256 bytes each.
Compactness: thanks to the use of NTRU lattices, signatures are substantially shorter than in any lattice-based signature scheme with the same security guarantees, while the public keys are around the same size.
Speed: use of fast Fourier sampling allows for very fast implementations, in the thousands of signatures per second on a common computer; verification is five to ten times faster.
Scalability: operations have cost O (n log n) for degree n, allowing the use of very long-term security parameters at moderate cost.
RAM Economy: the enhanced key generation algorithm of Falcon uses less than 30 kilobytes of RAM, a hundredfold improvement over previous design such as NTRU Sign. Falcon is compatible with small, memory-constrained embedded devices.

Every one can use a personal computer to mine Tidecoin. Even possable use mobile devices for mining, as the powerful soc is popular. Just download the wallet and enter a command to mine. The PoW algorithm Tidecoin use is yespower. This algorithm in particular is designed to be CPU-friendly, GPU-unfriendly.

Quantum computers could crack Bitcoin by 2022 (https://decrypt.co/28560/quantum-computers-could-crack-bitcoins-encryption-by-2022)
By Robert Stevens

Quantum computers could one day be used to crack the encryption of cryptocurrencies like Bitcoin. And that day could come sooner than anticipated.

A 4,000 qubit quantum computer could, theoretically, crack Bitcoin's encryption in a matter of seconds.
The current generation of quantum computers max out at 54 qubits.

A quantum computer capable of cracking Bitcoin's encryption could be just two years away.

If you had a powerful enough computer, you could, theoretically, take control of the Bitcoin blockchain. You could credit your account with free Bitcoin or prevent others from making transactions. Since the private key to each wallet can be derived from a public key, you could access the Bitcoin wallet of whomever you wished. The keys to the $163 billion castle would be yours—of course, in that scenario, Bitcoin’s price would surely plummet as soon as its claims of invulnerability were found to be baseless.

Quantum Computer Completed A 2.5-Billion-Year Task In 200 Seconds (https://www.intelligentliving.co/quantum-computer-2-5-billion-year-task-in-200-seconds/)
by Andrea D. Steffen December 18, 2020

Google was the first to achieve quantum supremacy in 2019. The company claims that its 53-qubit Sycamore processor performed a computation within 200 seconds. That same task would have taken the world’s most powerful supercomputer 10,000 years. The Sycamore is based on qubits represented by superconducting materials.

This year, a China team developed a photon-based quantum computer that demonstrated quantum supremacy – the second group to do so since Google. The device (called Jiuzhang) is made to carry out a single specific type of calculation— Gaussian boson sampling. It performed so well that it conducted a calculation in 200 seconds that would have taken the world’s best supercomputer 2.5 billion years to complete. That’s over half the age of Earth!
