Blockchain Application Scenarios and Their Benefits

Introduction – Blockchain has become a hot topic, but many people wonder what practical problems it can solve. This article surveys several meaningful blockchain use cases, summarizing their advantages and providing concrete examples, mainly from Tencent and other Chinese enterprises.

1. Information Sharing – Traditional information sharing suffers from centralised publishing or periodic batch reconciliation, which cannot meet real‑time requirements and lacks mutual trust. Blockchain’s inherent data consistency, P2P communication, immutability and consensus mechanisms enable a secure, real‑time, trust‑less information‑sharing channel. Example: Tencent’s “Public Welfare Find‑Person Chain” demonstrates how blockchain records can be used for reliable data exchange.

2. Copyright Protection & Legal Evidence – Conventional copyright registration is slow, costly, and vulnerable to tampering. By storing copyright metadata on a blockchain with timestamps, digital signatures and decentralized storage, the process becomes simpler, cheaper and tamper‑proof. Real‑world milestones include the formation of the “Legal Chain” alliance (Onchain, Microsoft China, 法大大) in 2016 and the launch of arbitration alliance chains by WeBank and others in 2017‑2018.

3. Traceability & Anti‑counterfeiting (Logistics) – Products pass through many stages, creating opportunities for fraud. Blockchain’s decentralised ledger makes data immutable, transparent and traceable, raising the cost of counterfeiting and allowing every node in the supply chain to verify product provenance. Notable deployments: Alibaba’s Cainiao uses blockchain for overseas goods traceability; Tencent signed a strategic cooperation with China Logistics & Procurement Federation to build a blockchain logistics platform.

4. Supply‑Chain Finance – Small and micro enterprises often lack financing because banks cannot trust them individually. When the entire supply‑chain is on‑chain, core enterprises’ credit can be leveraged to evaluate the whole chain, enabling full‑chain financing rather than isolated, point‑wise loans. The article illustrates the financing gap with a simple supply‑chain diagram and explains how blockchain‑based private‑key signatures and on‑chain contracts digitise assets for easier flow.

5. Cross‑border Payments – Traditional cross‑border settlements are slow, costly and rely on trusted intermediaries, leading to information asymmetry. Blockchain removes the middle‑man, provides real‑time settlement, reduces fees, and offers auditability that satisfies regulators. Existing participants include Ripple, Circle and several Chinese banks.

6. Asset Digitisation – Physical assets are hard to split and monitor, hindering liquidity. By tokenising assets on a blockchain, they become divisible, tradable and permanently recorded, lowering transaction costs and meeting compliance requirements. Example: Tencent’s “Micro‑Gold” app tokenises gold, allowing purchases as small as 0.001 g.

7. Tokens & Decentralised Currency – Bitcoin illustrates how blockchain solves both issuance (fixed supply, mining) and ledger tampering (chain structure, decentralised consensus). While Bitcoin remains the most successful token, the article notes the risks of other tokens lacking sovereign backing and the challenges of 51 % attacks and low throughput.

Conclusion – Blockchain offers diverse application scenarios beyond hype, yet real‑world adoption is still limited. Technical, regulatory and ecosystem‑wide interests pose the biggest hurdles, not the technology itself.
