At the moment when blockchain technology is booming, many blockchain networks such as Bitcoin, Ethereum, and Polka have sprung up like mushrooms after a rain. However, these independent blockchains are like digital islands, and data cannot be shared with each other, and assets are difficult to circulate, which seriously restricts the further development of the blockchain ecosystem. The emergence of blockchain interoperability is to solve this problem. So, what is blockchain interoperability? How does it achieve "dialogue" between different blockchains? What are the practical applications?
Blockchain interoperability refers to the ability of different blockchain networks to achieve data interaction, asset transfer and functional coordination. Just as people in different countries need translation to communicate smoothly, different blockchains also need specific technologies to achieve mutual "understanding" and collaboration due to different protocols, architectures and rules. Blockchains with interoperability allow users to freely transfer assets and call smart contracts on different chains, breaking the barrier between chains and building a more open and efficient blockchain ecosystem. For example, HashKey Exchange When exploring multi-asset trading services, we are also actively studying blockchain interoperability, striving to open up circulation channels for different blockchain assets for users.
The technical paths to achieve blockchain interoperability mainly include hash locking, sidechains/relay chains, and notary mechanisms. Hash locking realizes cross-chain atomic transactions without trusting a third party through smart contracts and hash algorithms; sidechains/relay chains act as bridges, connecting different main chains, and realizing two-way transfer of assets and data. Polkadot is a typical example of multi-chain interoperability based on relay chain Technology Implementation; notary mechanisms introduce trusted third parties to verify and guarantee cross-chain transactions. These technologies solve cross-chain problems from different angles and provide reliable guarantees for the interaction between blockchains.
The application prospect of blockchain interoperability is very broad. In the field of decentralized finance (DeFi), the free flow of assets on different public chains can be realized, which can integrate the liquidity of each chain and improve the efficiency of capital use. HashKey Exchange If interoperability technology is applied, users can easily trade digital assets on different chains; in the field of supply chain, blockchain systems used by different enterprises can realize data sharing through interoperability and optimize supply chain collaboration; in the field of government affairs and public welfare, interoperability can open up blockchain platforms among various departments and organizations to improve data collaborative efficiency. As the technology continues to mature, blockchain interoperability will promote blockchain applications to new heights.
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.
