In a QCon 2019 talk, Ant Financial’s deputy CTO Hu Xi outlines the company’s fifteen‑year journey reshaping payments and micro‑loans through blockchain, AI, security, IoT and cloud computing, and details the emerging cloud‑native, high‑availability, data‑intelligent architecture that will underpin the next generation of financial technology.
This article provides a comprehensive overview of blockchain technology, covering its fundamental concepts, layered architecture (protocol, extension, and application layers), implementation details across various programming languages, and a knowledge map to help developers understand and build blockchain-based products.
The article introduces blockchain fundamentals for programmers, covering asymmetric cryptography, public ledgers, double‑spending, transaction ordering, consensus mechanisms, proof‑of‑work mining, smart contracts, gas, token transfers, zero‑knowledge proofs, and self‑regulation, while relating each concept to familiar software engineering patterns.
The article argues that automatic formal verification of Ethereum smart contracts using deep learning and Hoare Logic is fundamentally impossible because pre‑ and post‑conditions must be manually specified, and it further critiques the overall concept of smart contracts as an overengineered and unnecessary feature of blockchain systems.
This article provides a comprehensive introduction to blockchain technology, covering its origins, development milestones, formal definition, structural classifications, key characteristics such as decentralization and immutability, as well as security mechanisms and current limitations, supported by references and illustrative diagrams.
This article examines blockchain's core mechanisms, its influence on system architecture—including tight coupling, security, privacy, and consensus challenges—and presents China Merchants Bank's practical implementation of a blockchain‑based cross‑border clearing system.
Ethereum is a blockchain platform that extends Bitcoin’s decentralized consensus with a Turing‑complete language, enabling developers to create smart contracts, token systems, decentralized autonomous organizations, and a wide range of financial and non‑financial decentralized applications, while addressing scalability, mining, and security challenges.
In this interview, blockchain specialist Zou Jun defines blockchain as an immutable, append‑only distributed ledger, explains its technical foundations, compares it with traditional databases, discusses public, consortium and private chain use cases, security concerns, and future prospects beyond finance.
Dubai’s Roads and Transport Authority announced plans to introduce a blockchain-powered vehicle lifecycle management platform by 2020, aiming to provide transparent, immutable records from manufacturing to scrappage for all vehicles in Dubai and eventually the UAE, enhancing trust among manufacturers, regulators, insurers, and owners.
The article examines how blockchain technology enables decentralized data marketplaces that let individuals reclaim control over their personal information, monetize it through smart contracts, and challenge the data‑driven advertising dominance of major tech giants such as Google and Facebook.
The article explains the concept of Decentralized Autonomous Organizations (DAOs) as blockchain‑based entities that encode governance rules in smart contracts, illustrates early attempts like the 2016 DAO project, and discusses the inherent security challenges of immutable code.
The article examines the 2018 outlook for enterprise blockchain, detailing performance, resilience, security, supportability, and integration challenges while outlining architectural principles, Hyperledger Fabric contributions, and the role of blockchain-as-a-service in moving from proof‑of‑concept to production deployments.
