The "2018 Ethereum Technology and Application Conference · China," co-hosted by CSDN and LinkTime (a leading Ethereum ecosystem builder), took place on June 3, 2018, in Beijing. The event brought together top global developers, Ethereum core team members, and project leaders to explore Ethereum’s ecosystem, core technologies, and innovative applications. Below are the key takeaways from the conference.
1. The Rise of Ethereum Developers
Speaker: Jiang Tao, Founder of CSDN
Developer Trends:
- 3.7% of developers own cryptocurrencies, with 70% entering the market during the 2017 surge.
- Two-thirds prioritize Ethereum technology.
- 54% of Ethereum/blockchain developers are based in Beijing, followed by Shanghai and Shenzhen.
Ecosystem Growth:
- 57.9% of developers plan to join Ethereum development within a year.
- Top applications: DeFi (Decentralized Finance), gaming, and IoT.
- Over 250,000 global developers actively contribute to Ethereum’s GitHub, with ~10,000 highly active.
- CSDN’s Initiative: Launching CODENetwork, a next-gen Ethereum developer community, to foster collaboration.
2. Ethereum’s Unmatched Ecosystem
Speaker: Jiang Yingying, Founder of LinkTime
Global Adoption:
- Ethereum remains the most imitated yet unrivaled blockchain platform.
- Top 200 cryptocurrencies include 63 Ethereum-based tokens.
Industry Mindset Shift:
- Unlike global peers focusing on collaboration, some Chinese developers prioritize "overthrowing" competitors—a risky approach during the learning phase.
3. Casper and Sharding: Technical Advancements
Speaker: Vitalik Buterin, Ethereum Founder
Casper PoS Workflow:
- Deposit: Stake ETH to become a validator.
- Wait Period: ~1 day for activation.
- Validation Roles: Finalize main-chain blocks and verify sharded chains.
- Rewards/Penalties: Avoid homogeneity (e.g., unique VPS, OS, client).
- Exit: Validators deactivate after 7 days; ETH withdrawal takes 4 months.
- Key Warning: Diversify validator setups to prevent systemic risks.
4. Ethereum’s "Superpowers"
Speaker: Karl Floersch, Ethereum Core Developer
Cryptoeconomics Course:
- Open-source curriculum covering design patterns, coding projects, and system building.
Plasma’s Potential:
- Enables scalability, dApp execution, and minimal-data storage.
Hash Functions:
- Four Traits: Preimage/2nd-preimage/collision resistance, Random Oracle.
- Three Uses: Key generation, signing, verification.
5. Smart Contract Security
Speaker: Jiang Xuxian, CEO of PeckShield
Threat Landscape:
- Vulnerabilities exist across exchanges, wallets, and smart contracts (e.g.,
transferFlaw,multiOverflow).
- Vulnerabilities exist across exchanges, wallets, and smart contracts (e.g.,
Mitigation Strategies:
- Conduct thorough audits pre-launch.
- Implement emergency response protocols.
- Adopt bug-bounty programs for ecosystem health.
