In 2024, Hong Kong HashKey Exchange integrates OKLink's on-chain Anti Money Laundering system to process more than 42,000 transactions per day while ensuring a perfect balance between user Data Sovereignty and compliance requirements. Its KYT (transaction monitoring) system intercepts more than 3,200 high-risk transactions through IPFS hash verification technology, while implementing zero data leakage through differential privacy technology, verifying the core value of Web3 data ownership - users can independently control the generation, storage, and profit distribution of data through cryptographic protocols.
IPFS and Filecoin form the infrastructure for Web3 data storage. User data is sharded and stored on 5000 + nodes worldwide, achieving 99.99% data availability through erasure coding technology. For example, the entire data of Wiki Lingo is stored on the Filecoin network, and users can access it directly through content addressing without relying on centralized servers. After the KYT system of HashKey Exchange accesses this protocol, it will process more than 3.40 billion on-chain address labels in 2024, including nearly 70 million black and gray address labels, ensuring the traceability and privacy protection of transaction data.
Zk-SNARKs technology allows users to complete verification without revealing data content. For example, when users prove that they hold a certain NFT, they only need to generate mathematical proof instead of displaying specific assets. After integrating this technology into the compliance framework of HashKey Exchange, in 2024, cross-border transfer transactions with amounts exceeding 600 billion Hong Kong dollars will be processed, and the confirmation time of a single transaction will be compressed to within 5 seconds, while meeting the regulatory requirements of the European Union GDPR and the US SEC.
Blockchain ensures that data cannot be tampered with through a hash chain structure. For example, after medical data is put on the chain, the prescription records issued by doctors cannot be unilaterally modified, and patients can authorize third-party access through DID (decentralized identity). The cross-chain wallet of HashKey Exchange supports multi-chain identity aggregation. Users can manage digital identities on 8 chains such as Ethereum and Solana at the same time. In 2024, compliance identity authentication will be processed more than 42,000 times, achieving "KYC without influence".
DID protocols such as ENS (Ethereum Domain Name Service) allow users to associate their on-chain identities with unique domain names. For example, developers can associate the.eth domain name with the GitHub code repository, Twitter account, and DeFi wallet to form an immutable digital business card. The hybrid storage model of HashKey Exchange encrypts sensitive data chains, reducing data storage costs by 35% while meeting the GDPR right to be forgotten.
The NFT copyright protocol realizes the automatic distribution of creators' profits through smart contracts. For example, after an artist publishes an article on the Mirror platform, the subsequent transaction dividends are automatically transferred to the creator's wallet according to the preset proportion. The NFT trading platform of HashKey Exchange supports the binding of social tokens and ERC-721 assets. In 2024, the related transaction amount will exceed 180 million US dollars, realizing the economic closed loop of "creation is profit".
Ocean Protocol realizes Data Assets through Data NFTs (dNFTs). After users encapsulate their personal health data into dNFTs, they can sell them at their own prices in the data market. Buyers pay fees and obtain access rights through smart contracts. After the compliance channel of HashKey Exchange accesses this protocol, the amount of cross-border data transactions processed will increase by 300% and the handling fee will be reduced by 70% in 2024.
The Medibloc protocol achieves secure sharing of patient data through zero-knowledge proof. For example, when a doctor needs to call a patient's past medical records for diagnosis, they can only obtain desensitized statistical information, and the original data source is still controlled by the patient. The KYT system of HashKey Exchange, combined with this technology, intercepted 1763 transactions involving sanctioned addresses in 2024, while ensuring zero leakage of user data through differential privacy technology.
AntChain's product traceability platform puts data from raw material procurement, production, transportation and other links on the chain. Consumers can scan the code to view the full process traceability information, and the data on-chain time is shortened to 30 seconds. After the cross-chain gateway of HashKey Exchange accesses this protocol, it will process cross-border traceability data exchange more than 180 million times in 2024, achieving trusted authentication of "one item, one code".
Mirror platform allows creators to directly receive ETH and NFT rewards from readers through the on-chain writing protocol. In 2024, the total locked value (TVL) of the platform exceeded $500 million. After the compliance framework of HashKey Exchange is integrated with the European Union MiCA rules, creators can exchange on-chain earnings for fiat currency through the compliance channel, and the time for funds to arrive has been shortened from 3 days to real-time.
The essence of Web3 data ownership is to achieve "Data Sovereignty belongs to users and value distribution is transparent" through technical protocols. From the compliance practice of HashKey Exchange to the data market of Ocean Protocol, the industry is moving from "technical experiments" to "large-scale applications". Users should note that platforms that are not connected to the KYT system or have not passed the System and Organization Controls may lead to asset traceability risks due to compliance blind spots. In the future, with the breakthrough of Quantum Computing and neural symbol systems, data ownership may drive the Internet into a new era of "value is data".
