Introduction
Blockchain technology continues to face numerous technical challenges, such as scalability, data privacy, and the use of mainstream programming languages for smart contracts. In 2019, Qtum Quantum Chain 2.0 provided solutions to these pressing issues.
On September 25, Qtum's CTO, Wenbin Zhong, participated in an AMA titled "Beep Expert Talk: Are Public Chains Still Relevant?" He discussed Qtum 2.0's strategies for 2019 and highlighted key focus areas for the coming year, including privacy assets, blockchain-cloud integration, the Qtum-x86 virtual machine, and smart contract PoS.
Core Insights
Qtum is not designed to solve a specific technical problem but focuses on refining blockchain infrastructure to support future decentralized applications. Key directions for Qtum Quantum Chain 2.0 include:
- Privacy Assets: Enabling the creation of privacy-focused tokens and contracts.
- Blockchain-Cloud Integration: Exploring synergies between blockchain and cloud computing.
- Qtum-x86 Virtual Machine: Supporting mainstream programming languages for developer flexibility.
- Smart Contract PoS: Enhancing staking flexibility and security.
The upcoming hard fork upgrade will significantly lower the barrier to smart contract usage, improve developer efficiency, and increase network stability, marking Qtum's most substantial upgrade since its mainnet launch.
Competitive Differentiation
Q: How does Qtum define its competitive edge?
Zhong Wenbin: Qtum is a permissionless public chain that combines Bitcoin's UTXO model with Ethereum's smart contracts, innovating as a "major upgrade" to Bitcoin. Qtum's PoS consensus lowers the barrier to running full nodes, making it the third-largest decentralized network globally.
Qtum's focus is on infrastructure refinement rather than solving niche problems. Future priorities include privacy assets, blockchain-cloud integration, and the Qtum-x86 virtual machine.
Latest Developments
Q: What are Qtum's recent advancements?
Zhong Wenbin: Qtum 2.0's first hard fork, scheduled for October 16, introduces:
- Privacy Assets: Tokens with customizable privacy features.
- Blockchain-Cloud Integration: Bridging the gap between synchronous blockchain logic and asynchronous cloud infrastructure.
- Qtum-x86 Virtual Machine: Enabling developers to use mainstream languages like C++ and Rust.
- Smart Contract Staking: Increasing staking flexibility while protecting staker权益.
These innovations address gaps in the current blockchain ecosystem.
PoW vs. PoS
Q: What are the benefits and drawbacks of Qtum's PoS consensus?
Zhong Wenbin: PoW suits cryptocurrency-focused projects (e.g., Bitcoin), while PoS excels in scalability for applications. Qtum's hybrid model—combining Bitcoin's UTXO, Ethereum's smart contracts, and PoS—offers a balanced approach.
Cross-Chain Technology
Q: Is cross-chain technology essential?
Zhong Wenbin: Cross-chain solutions primarily address value transfer between chains, a need already met by exchanges. True cross-chain applications remain speculative.
Public Chain Monetization
Q: Can public chains sustain without盈利 models?
Zhong Wenbin: Most public chains lack viable monetization strategies. While some diversify into exchanges, long-term success requires creating value before monetizing.
Competing with New Public Chains
Q: How can established chains like Qtum compete with newer projects?
Zhong Wenbin: Qtum embraces innovation while building on Bitcoin and Ethereum's foundations. The focus is on协作, not competition, as blockchain infrastructure is still in its infancy.
