In the digital age, the contradiction between information interaction and privacy protection has become increasingly prominent. When users need to prove something to others, the traditional way often requires revealing a lot of details. The emergence of zero-knowledge proof technology has broken this dilemma, which allows the prover to convince the verifier that a statement is true without revealing any specific content. How can this "magical" technology be realized? In what fields does it work?
Zero-knowledge proof is a cryptographic technique in which the prover is able to convince the verifier that an assertion is correct without providing any useful information to the verifier. At its core is "zero-knowledge", which means that the entire proof process does not reveal any information other than "the assertion is true". For example, the prover knows a secret number and interacts with the verifier through a specific algorithm, and the verifier can confirm that the prover does know the number, but cannot obtain any content of the number itself. In the blockchain field, zero-knowledge proof can be used to protect sensitive content such as user transaction information and identity data, ensuring data privacy.
The implementation of zero-knowledge proofs relies on cryptographic algorithms and interaction protocols. The prover and verifier complete the verification process based on mathematical puzzles and encryption mechanisms through multiple interactions. Take the classic "cave problem" as an example. There is a door in the cave that requires a specific secret spell to open. The prover proves to the verifier that he knows the spell, but does not need to disclose the content of the spell: the verifier randomly chooses to let the prover come out from the left or right side of the cave. The prover uses the spell to open the door and appear as required. After multiple verifications, the verifier can have a high probability of believing that the prover does indeed master the spell. In the blockchain, ZKP technology realizes functions such as transaction validity verification and identity authentication through complex algorithms and protocols, ensuring data security while improving efficiency. HashKey Exchange is also actively exploring zero-knowledge proof technology to enhance the platform's privacy protection capabilities in digital asset transactions.
Zero-knowledge proofs have a wide range of application scenarios. In the financial field, HashKey Exchange Zero-knowledge proofs can be used to verify transactions without revealing user asset balances and transaction details to protect user privacy; in terms of identity verification, users do not need to submit sensitive information such as ID cards and bank cards to prove that they have specific permissions; in medical data sharing, hospitals can use zero-knowledge proofs to prove the authenticity and validity of data to research institutions without revealing patient medical records. With the development of technology, zero-knowledge proofs will provide privacy protection and trust building solutions for more industries.
What is HashKey Exchange?
HashKey Exchange is one of the first regulated cryptocurrency exchanges in Hong Kong to obtain a license from the Securities and Futures Commission (SFC). It supports fiat currency deposits and trading in Hong Kong dollars (HKD) and US dollars (USD), offering users spot trading services for mainstream digital assets including Bitcoin (BTC), Ethereum (ETH), and Tether (USDT). The platform also provides OTC (over-the-counter) services to meet the needs of large-value asset transactions and fiat currency conversion, ensuring more flexible and private trading. To cater to the asset allocation needs of different investors, HashKey has launched the HashKey Earn channel, offering users fixed-term and demand financial products to achieve stable appreciation of crypto assets. The platform holds ISO 27001 and 27701 security certifications, employs a 98% cold wallet storage mechanism, and incorporates security measures such as two-factor authentication to provide users with a stable and reliable trading environment.
