A brief introduction to what zero-knowledge proof is.
Zero-Knowledge Proof (ZKP) is a cryptographic protocol that allows one party (the prover) to prove to another party (the verifier) that a statement is true without revealing any specific information about the statement. The concept of zero-knowledge proof was proposed by Shafi Goldwasser, Silvio Micali and Charles Rackoff in 1985 and has been widely used in cryptography and computer science.
Three major properties of zero-knowledge proof
1. Completeness:
• If the statement is true, an honest prover can convince an honest verifier.
2. Soundness:
• If the statement is false, the probability that a non-cheating prover can convince an honest verifier is very small (usually negligible).
3. Zero-Knowledge:
• If the statement is true, the verifier does not obtain any additional information beyond the statement.
Types of Zero-Knowledge Proofs
1. Interactive Zero-Knowledge Proofs:
• The prover and the verifier prove the truth of a statement through multiple rounds of interaction.
2. Non-Interactive Zero-Knowledge Proofs (NIZK):
• The prover generates a single proof that can be verified by any verifier without further interaction.
The application of zero-knowledge proofs, to put it bluntly, is the process of knowing that you are awesome but not knowing how you are awesome. The token worth paying attention to in this field is zkSync~
Zero-knowledge proofs have a wide range of applications in many fields, including but not limited to:
1. Blockchain and cryptocurrency:
• Zero-knowledge proofs are used to ensure the privacy and security of transactions, such as the application of zk-SNARKs and zk-STARKs technology in Zcash and other privacy coins.
2. Authentication:
• Verify the identity of the user without exposing the user's password or other sensitive information.
3. Secure multi-party computation:
• Multiple parties perform joint computation without disclosing their private data.
4. Data privacy protection:
• Protect data privacy and ensure that sensitive information is not disclosed when sharing or processing data.
Example
Example of interactive zero-knowledge proof: map coloring problem
Suppose there is a map, and the prover claims that the map can be colored with four colors so that the colors of adjacent regions are different. The verifier wants to verify this claim, but does not want to know the specific coloring scheme.
1. The prover first colors the map with four colors.
2. The prover masks the color of each region and randomly swaps the color labels.
3. The prover shows the swapped map to the verifier.
4. The verifier randomly selects a pair of adjacent regions and asks the prover to reveal the colors of these regions.
5. The prover reveals the colors, and the verifier checks whether the colors of this pair of adjacent regions are different.
6. Repeat the above steps multiple times, and the verifier selects a different pair of adjacent regions each time.
If the prover can correctly reveal the colors each time and the colors are different, then the verifier can have a high degree of confidence that the prover does have a correct coloring scheme without knowing the specific scheme.
Summary
Zero-knowledge proof is a powerful cryptographic tool that can prove the authenticity of certain statements without leaking information. It has broad application prospects in fields such as blockchain, identity authentication, and data privacy protection.

It is neither difficult nor easy to do contracts 1. The difficult part is human greed and the difficult part is position control 2. The easy part is short-term + margin + your own trading system (for example, you can get 300U of income every day and leave) 3. But you must choose a coin that suits your style. I have been doing short-term $OP Why did I choose him? Because I am a dead short seller. I can’t help it🤷🏻♀️ 4. Just use the technical analysis that suits you, such as order flow, smart money, and liquidation chart

$BTC 1. 2013: The first big bull run and China ban
• Rise: In April 2013, the price of Bitcoin rose rapidly from $100 to $260, mainly due to the safe-haven demand caused by the Cyprus financial crisis. • Market crash: In December 2013, the People’s Bank of China banned financial institutions from processing Bitcoin transactions, and the price of Bitcoin fell from around $1,000 to a few hundred dollars. 2. 2017: Historic bull run and regulatory crackdown • Rise: Throughout 2017, the price of Bitcoin rose from $1,000 to $20,000. Driving factors include the surge in global market interest in cryptocurrencies, the ICO (initial coin offering) boom, and widespread publicity for blockchain technology.
