Welcome to SORA-QAI

* PoW / PoS hybrid consensus

* Support for Quantum and AI resistance private - public key

* Support for Schnorr Schnorr signatures without restrictions that do not require BIP340

* Support for Schnorr aggregated signatures that can aggregate 5,000 keys within a few seconds

####
SORA L1 Blockchain - with Quantum & AI resistance implemented !

Features: [Supported after v3.92.15]

I, Conventional bitcoin P2PKH-ECDSA transactions and Quantum & AI resistance transactions are separated, allowing for individual balance management.

II, There is a feature that allows for a one-click transition from bitcoin P2PKH-ECDSA to Quantum & AI resistance transactions.

III, Quantum & AI-resistant transactions have been made compact, so the transaction fees are only slightly higher than those for bitcoin P2PKH-ECDSA.

IV, Both bitcoin P2PKH-ECDSA and Quantum & AI resistance transactions are configured for multi-signature setups, ensuring that bitcoin P2PKH-ECDSA verification is carried out even on older nodes for added security.

V, We have implemented support for Schnorr signatures. Additionally, we successfully removed the restriction on specifying the Y-coordinate as even for public keys as stated in BIP340, making it possible to use any ECDSA key for Schnorr signatures.

>> This is how it works. Please check the video for details.

## SORA-L1 Blockchain-Core (S ...), (sora1 ...), (0x ...)

When obtaining a new address, you will choose from 4 types:

* An address for ECDSA: e.g (S ...)

* An address for Quantum AI-resistant: e.g. (sora1 ...)

* An address for Quantum AI-resistant Schnorr aggregated signatures (5000 keys): e.g. (sora1 ...)

* Ethereum-style address: e.g. (0x ...)

If you generate without checking any options, it will be for ECDSA. The rest are determined by the presence or absence of checks. Note that the Ethereum-style address is still under development. It will sync with Ethereum’s private key to obtain the same public key, which will be used to operate SORA.

Supported contract address (for DAOs). [bitcoin-RPC getnewethaddress]

#### Q: Are there any companies utilizing the SORA blockchain?

A: **Yes, there are. Features of SORA that utilize the SORA blockchain,
such as the drive inspection function, have been adopted by major Japanese computer sales and repair companies. [e.g. Akihabara, Tokyo]**

We will continue to steadily increase the use cases of the blockchain.

Thank you for your understanding.

## About Quantum Resistance

#### Introduction

Quantum resistance has become a topic of discussion, but I have become skeptical about whether it is an implementation that needs to be immediately applied to blockchain.

Certainly, due to Shor's algorithm, problems arise concerning RSA, However, blockchain does not depend on the RSA mechanism.

While it does grapple with the common issues of the discrete logarithm problem, the usage and effects differ, so the problems with RSA are not the problems of the blockchain.

In reality, even if quantum computers were to solve it, it seems that the current system might be sufficient for about 30 years.

#### Quantum Computers and Shor's Algorithm

Quantum computers process information using quantum bits (qubits). This allows them to perform calculations much faster than classical computers. Shor's algorithm is one of the algorithms executed on quantum computers, efficiently factoring large numbers.

\[ | \psi \rangle = \cos\left(\frac{\theta}{2}\right) | 0 \rangle + e^{i\phi} \sin\left(\frac{\theta}{2}\right) | 1 \rangle \]

Modern public key cryptography(RSA) relies on the fact that factoring large numbers is not computationally feasible in a realistic timeframe. However, quantum computers can factor large numbers in a realistic timeframe using Shor's algorithm.

Originally, the phase information φ of a quantum bit in superposition cannot be directly observed. However, by utilizing quantum Fourier transform, this phase information can be converted into the frequency domain, making it possible to transform it into an observable probability amplitude of the quantum bit's particle nature.

\[ f(x) = a^x \mod N, \;\gcd(a, N) = 1 \] \[ |x\rangle = H\; \otimes \;H\; \otimes \cdots \otimes \;H \;|00 \cdots 0\rangle = \sum_k |k\rangle \rightarrow f(x) \rightarrow |x\rangle\; \otimes \;|f(x)\rangle \] \[ |f(x)\rangle = \sum_k |k\rangle \rightarrow \text{Collapse} \rightarrow |f(x)\rangle \rightarrow f(j),\ j: \text{the chosen solution} \] \[ \therefore\;|j\rangle = \frac{1}{\sqrt{n}} ( |m_1\rangle + |m_2\rangle + \ldots + |m_n\rangle ) \] \[ \text{n: the number of superposed states on the input register} \] \[ m_1 \cdots m_n: \text{the respective states} \]

\[ \therefore\;QFT\_{2^n}\;|j\rangle \rightarrow \frac{1}{\sqrt{2^n}} \sum_{k=0}^{2^n - 1} e^{2\pi i j k / 2^n} |k\rangle \]

## About SORA implements transactions, Smart contracts, AI-NFTs, Quantum Resistant Key.

#### AI-NFT

Support for ownership management, metaverse, drive(HDD/SSD/NVMe) inspection and advanced scientific analysis ... etc. Web3 - Blockchain - Multidimensional NFT by SORA Network. We aim to popularize multidimensional NFTs that can be built by direct product based on Web3 - blockchain technology. The base development has already been completed, and 1-dim NFT, 2-dim NFT, and 4-dim NFT are operating normally on SORA Network.

What kind of use is there? For example, when analyzing meteorological observation data with a blockchain. If the "wind direction" and "wind strength" at a certain point are used as data, it will be a 2-dim NFT. This 2-dim NFT operate to record data on the SORA-blockchain. And if you give a special NFT to blockchain with action by direct product or comparison, you can get the result from the blockchain. By the way, regarding the first goal of the SORA project, "Achieving drive inspection statistics on the blockchain", we achieved with the 4-dim NFT (i-sector). Now it can operate SSD/NVMe safely.

\[ a_0 \cdots a_n \in \text{AI-NFT} \] \[ T_{ij} = a_0 \otimes a_1 \otimes a_2 \otimes \cdots \otimes a_n \]

#### 16 passphrase, restore wallet completely

With this kind of feeling, you can build an NFT that can directly product the conventional tokens with smart contract and raise the dimension. Smartly adapts to any application ... Reborn as a general blockchain! Then, No need a hard-ware wallet, No need a paper wallet, No need a buckup, in SORA Network. No need, those backup, hardware wallet, paper wallet, and so on. Why? because Using 16 passphrase, restore wallet completely (Coins and NFTs are safe).

\[ f: D^{16} \longrightarrow C \]
