Introduction
Hong Kong recently made history by launching Asia's first Bitcoin and Ethereum spot ETFs in late April, solidifying its position as a pioneering hub for virtual asset development. This milestone reflects the growing mainstream acceptance of cryptocurrency markets and the expanding applications of blockchain technology.
While most recognize blockchain as the decentralized ledger powering cryptocurrencies, its potential extends far beyond digital currencies and financial markets. However, concerns about energy consumption and data storage costs have prompted researchers to develop more efficient solutions.
Understanding Blockchain's Challenges
Blockchain technology offers:
- Immutability: Tamper-proof transaction records
- Transparency: Visible and verifiable data trails
- Decentralization: Distributed network security
Yet two critical limitations persist:
- High Energy Consumption: Proof-of-work mechanisms require intensive computational power
- Storage Costs: On-chain data storage becomes prohibitively expensive at scale
Most implementations use hybrid approaches:
- On-chain: Stores critical transaction records
- Off-chain: Keeps supplementary data in external databases
