By 2025, the compliance sandbox of Hong Kong HashKey Exchange integrates zkSync 2.0 and BNB Chain, achieving a 90% increase in cross-chain asset mapping efficiency, processing DeFi transactions over 10 trillion Hong Kong dollars, and reducing Gas fees by 80%. This performance revolution driven by blockchain technology is pushing Ethereum's throughput from 30 TPS to the 10,000-level threshold and reducing transaction costs by 99% through the dual path of Layer 2 off-chain computing and sharding on-chain scaling.
Optimistic Rollups achieves low-cost scalability through the "fraud proof" mechanism. For example, Arbitrum One's daily transaction volume exceeded 30 million transactions, Gas fees were reduced to 1/100 of the mainnet, and more than 1 billion NFTs were processed and minted by 2025. ZkSync 2.0's Zero-Knowledge Proof (ZKP) technology allows users to anonymously verify asset holdings, reducing the risk of data leakage by 99%. In 2025, it processed more than 500,000 cross-chain transactions and shortened confirmation time to 3 seconds. HashKey Exchange's cross-chain gateway integrates Polygon and zkSync 2.0, processing cross-chain asset mapping more than 500,000 times in 2025, and settlement time was shortened from 3 days to 3 minutes.
The Connext protocol builds off-chain payment channels through multi-signature smart contracts. For example, a certain gaming platform uses a state channel to achieve "zero gas fee" item transactions, processing more than 2 million transactions per day with a latency of less than 100 milliseconds. HashKey Exchange's DeFi aggregator integrates dynamic pricing contracts, and by 2025, it will process voting pledge loans exceeding 600 billion Hong Kong dollars, reducing fraud rates by 42%.
Ethereum sharding achieves "secondary scaling" through random sampling of validators. For example, 64 sharding chains deployed in 2025 will increase TPS to 100,000 level and reduce storage costs by 70%. BNB Chain's three-chain collaboration (BSC, op BNB, BNB Greenfield) supports thousands of transactions per second, processing over 1 billion NFTs in 2025 and reducing storage costs by 70%. HashKey Exchange's compliance sandbox integrates PoW and PoS chains, and the efficiency of cross-chain transaction strategy formulation will increase by 200% in 2025.
The sharding chain shares the security of the main chain through data availability sampling (DAS) technology. For example, a medical platform stores patient data through the sharding chain, trains AI models locally on edge nodes, generates precise treatment plans after federated updates, and the data does not leave the domain with an accuracy rate of 92%. Sharding technology completely breaks the security silos of the multi-chain ecosystem. Attackers need to control more than 30% of validators to launch effective attacks, which improves security by 5 times.
