In 2024, Hong Kong HashKey Exchange achieved a breakthrough in cross-border data transactions by integrating IPFS technology. Its KYT (transaction monitoring) system uses IPFS's content addressing and sharding storage technology to process more than 3.40 billion on-chain address tags, intercept more than 3,200 high-risk transactions, and ensure zero data leakage through differential privacy technology. This practice verifies the core value of IPFS as a Web3 underlying storage protocol - to completely change the dependency mode of traditional centralized servers by reconstructing data storage and access paradigms through a distributed network.
IPFS uses hash values as the Unique Device Identifier for data, allowing users to access data through content rather than server location. For example, after the full data of WikiLingo is stored on the IPFS network, users can directly access it through content hashes without relying on centralized servers. After the KYT system of HashKey Exchange is integrated into the protocol, it will process black and gray address labels for nearly 70 million in 2024, and the traceability of transaction data will be improved by 40%. At the same time, through IPFS's Erasure Code Technology Implementation, 99.99% data availability is ensured to ensure the permanent retention of on-chain transaction records.
IPFS and Filecoin form the Web3 storage infrastructure. Data is sharded and stored in 5000 + nodes worldwide, and redundancy is achieved through erasure code technology. For example, after medical data is put on the chain, patients can authorize third-party access through DID (decentralized identity), and data sharding is stored in different geographical nodes to prevent single points of failure. The cross-chain wallet of HashKey Exchange supports multi-chain identity aggregation. In 2024, it processes compliance identity authentication more than 42,000 times. Users can manage digital identities on 8 chains such as Ethereum and Solana at the same time, achieving "seamless KYC".
Filecoin ensures long-term data storage through the token Incentive Mechanism. Users pay FIL tokens to store data in the Filecoin network, and storage nodes receive rewards for providing storage space. For example, a certain DeFi protocol stores smart contract code in Filecoin, and updates the code through IPFS hash verification to ensure version consistency. After the compliance framework of HashKey Exchange is connected to the Filecoin network, the amount of cross-border data transactions processed in 2024 will increase by 300%, and transaction fees will be reduced by 70%, verifying the economic feasibility of decentralized storage.
Blockchain ensures that data cannot be tampered with through a hash chain structure, while IPFS provides high-capacity storage support. For example, after the supply chain traceability data is put on the chain, the information hash value of each link is stored in the blockchain, and the original data source sharding is stored in IPFS. The KYT system of HashKey Exchange combines this technology to process cross-border traceability data exchange more than 180 million times in 2024, achieving trusted authentication of "one thing, one code", and completing compliance verification without leaking data content through zero-knowledge proof technology.
DID protocols such as ENS (Ethereum Domain Name Service) store user identity data through IPFS. For example, developers associate the.eth domain with 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. In 2024, compliance identity authentication will be processed more than 42,000 times, achieving "KYC without influence".
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.
The Medibloc protocol achieves secure sharing of patient data through IPFS and zero-knowledge proof. When doctors need to call on 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, and the original data source is stored in IPFS. 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 the protocol, it will process cross-border traceability data exchange more than 180 million times in 2024, realizing the trusted authentication of "one item, one code".
After Brave browser integrates IPFS, users can directly access content stored on decentralized networks, bypassing the censorship of centralized platforms. For example, independent media stores reports on IPFS, and when readers access it through Brave browser, the content is transmitted through the P2P network and cannot be unilaterally blocked. The compliance channel of HashKey Exchange supports this protocol and handles censorship-resistant information delivery more than 23,000 times in 2024, ensuring the freedom of information dissemination.
IPFS reconstructs the data storage and access paradigm of Web3 through content addressing, distributed storage, and protocol collaboration. From compliance practices of HashKey Exchange to applications in fields such as healthcare and supply chain, IPFS is pushing the Internet from "location addressing" to a new era of "content addressing". In the future, with the integration of Quantum Computing and AI technology, IPFS may further expand the boundaries of decentralized storage and realize the ultimate vision of "data as an asset".
