Key Competitive Points of Public Chains and Insights from the GIAC Shenzhen Conference

From June 1‑2, the author attended the GIAC conference in Shenzhen, listening to several blockchain talks and discussing with speakers, then compiled personal reflections.

Public‑chain competitive points : Bytom emphasizes native multi‑asset support via an improved UTXO model; Zilliqa targets scalability through network sharding and PBFT consensus while using a functional language for smart contracts; Nebulas and ASCH focus on DApp support and developer incentives, with Nebulas treating DApps as smart contracts and ASCH as side‑chains. ThunderDB proposes a decentralized SQL database built on a master‑subchain model, recording database binlogs on‑chain for generic data anchoring.

Other projects such as YoYow and Gongxinbao concentrate on vertical domains—content and personal data—leveraging blockchain to tokenize assets and enhance privacy compliance (e.g., GDPR). The author notes that each team makes trade‑offs between performance, new features, and token economics, and that the ultimate success depends on attracting users to the ledger.

Regarding alliance chains and financial applications, speakers highlighted mixed public‑/private‑chain deployments, Fabric improvements, and use cases in traceability and anti‑counterfeiting. While blockchain cannot guarantee data truth, it can raise the cost of forgery. Governance challenges include defining admission criteria, exit mechanisms, and token‑based incentives, with examples such as EOS‑style financial‑institution alliances.

The author concludes that despite uncertainties, experimenting with different architectures, governance models, and token economics is valuable for the evolution of blockchain technology.
