Here is a detailed explanation of **White Paper Sonic**, which includes the zk-SNARK protocol and blockchain projects related to the name "Sonic". Since there are several different entities using this name, I will distinguish between:
### **1. Sonic Protocol (zk-SNARK) White Paper**
**Title**: *"Sonic: Zero-Knowledge SNARKs from Linear-Size Universal and Updatable Structured Reference Strings"*
**Authors**: Mary Maller, Sean Bowe, Markulf Kohlweiss, and Daira Hopwood (2019).
**Link**: [arXiv:1901.01722](https://arxiv.org/abs/1901.01722)
#### **Main Content of the White Paper**:
1. **Background**:
- Sonic is designed to overcome the limitations of previous zk-SNARKs (like Groth16) that require a *trusted setup* specific to each program.
- The goal is to create a **universal zk-SNARK** with high efficiency.
2. **Key Innovations**:
- **Universal Structured Reference String (SRS)**:
- SRS can be used for multiple programs simultaneously, no need for repeated setups.
- **Updatable**: New participants can contribute to the setup process to enhance decentralization and security.
- **Polynomial Commitments**:
- Using polynomial commitments to reduce proof size and verification time.
- **Non-Interactive**: Proofs can be verified without interaction between prover and verifier.
3. **Implementation**:
- Implemented in projects like **Filecoin** (for proof-of-replication) and **Zcash**.

### **2. Sonic Token White Paper (Blockchain Project)**
Several projects with the name "Sonic" have their own whitepaper documents, for example:
#### **a. SonicSwap (DEX on BSC)**
- **Focus**: Decentralized exchange with low cost and high speed features.
- **Token**: $S (Sonic Token).
- **General Whitepaper Content**:
- **Token Economics**: Supply allocation, staking mechanisms, and burning (burn).
- **Governance**: Token-based voting for protocol decisions.
- **Roadmap**: Development of features such as cross-chain swaps.
- **Link**: Usually available on the official project website (e.g.: [sonicswap.io](https://sonicswap.io)).
#### **b. Sonic Chain (Blockchain Gaming)**
- **Focus**: Blockchain specifically for games with fast transactions and low costs.
- **Whitepaper**: Explains the consensus architecture, in-game NFTs, and integration of the $SONIC token.

### **3. Key Differences**
| Aspect | Sonic Protocol (zk-SNARK) | Sonic Token (SonicSwap/etc.) |
|----------------|---------------------------|-----------------------------|
| **Type** | Cryptographic Protocol | Crypto/utility asset token |
| **Function** | Zero-knowledge proof | Payment/governance tools in DEX|
| **Whitepaper** | Technical/mathematical | Business/token economy |

### **4. How to Check the Official Whitepaper**
1. **For Sonic Protocol**:
- Use academic links (arXiv) or official GitHub repositories.
2. **For Sonic Token**:
- Visit the project's website and look for the *Documentation* or *Whitepaper* section.
- Verify token contracts on Etherscan/BscScan to avoid scams.
---
### **5. Important Warnings**
- **Don't be fooled** by projects that only use the name "Sonic" without real products.
- The token whitepaper must clearly explain **use case, team, and roadmap**. If not, it may be a fake project.
---
### **Conclusion**
- **Sonic Protocol (zk-SNARK)**: Its whitepaper is technical, focusing on mathematical innovations.
- **Sonic Token**: Its whitepaper is more about token economics and practical applications.
- Always verify the source of the whitepaper to avoid scams.
Thank you for following, this is a token recommendation that will rise in the coming weeks. The decision is in your hands.
In the future, I will share some if my followers reach 50.
My name is Haqi and I hate fiat, thank you.
