Blockchain Technology

How chain data is shaped, and how to index, stream, store and model it. 14 chapters, 22 hands-on exercises, 7 end-to-end projects and a private GitHub repo of runnable code

Blockchain does not remove trust. It moves trust into code everyone can verify.

Free, code-first Solidity guide - 13 chapters from fundamentals to DeFi, security, gas optimization, and production testing with Foundry.

Digitale Transformation war das Hype-Thema vor KI. Es gibt allerdings einen nicht geringen Anteil an Fach- und Führungskräften, deren Wissen darüber weiter ausbaufähig ist. Dieses Buch ist eine Einführung für alle diejenigen, die keine "digitalen Pioniere" sind, sondern wissen wollen, was aus dem Thema Digitalisierung auf sie zukommen kann und aus dem Thema KI zusätzlich auf sie zukommen wird.

Blockchain in 2025 is no longer about hype. It’s about execution, regulation, and real business value. This report explains where blockchain is delivering today and how leaders should act next.

A rigorous framework for leveraged prediction markets: payoff geometry, microstructure, finality, credit, and protocol design, with empirical studies of Polymarket and Kalshi.

Every second, a machine makes a decision for you. Can it prove it? Most AI can’t. Proof of Intelligence shows leaders, architects and builders how to combine AI and blockchain into systems that can prove where their data came from, what they did and who is accountable.

Master offensive and defensive security techniques across smart contracts, DeFi protocols, bridges, rollups, consensus systems, and next-generation Web3 infrastructure.Blockchain ecosystems secure billions of dollars in digital assets, making them a persistent target for sophisticated cyberattacks. From reentrancy vulnerabilities and oracle manipulation to flash loan exploits, bridge compromises, governance attacks, and Layer-2 weaknesses, blockchain security requires expertise spanning cryptography, distributed systems, protocol engineering, and adversarial analysis.

Design, Engineer, and Deploy High-Performance Algorithmic Trading Infrastructure for Digital Asset MarketsCryptocurrency markets operate continuously, generating vast streams of market data across centralized and decentralized exchanges. Competing in these markets requires far more than a collection of trading scripts. It demands a rigorous combination of low-latency systems engineering, quantitative modeling, market microstructure analysis, distributed computing, machine learning, and production-grade risk management...

A Comprehensive Engineering Guide to Smart Contract Auditing, EVM Internals, DeFi Exploitation, Protocol Economics, and Blockchain SecuritySmart contracts operate in environments where code, financial assets, cryptographic authorization, and economic incentives interact directly. A subtle implementation error can compromise access controls, corrupt accounting, undermine protocol solvency, or expose digital assets to irreversible loss. Understanding these risks requires more than familiarity with Solidity syntax. It demands a rigorous examination of execution semantics, storage architecture, transaction ordering, protocol mathematics, and the assumptions that connect individual contracts to larger decentralized systems.Smart Contract Security: Finding DeFi Vulnerabilities is a comprehensive, implementation-focused engineering reference to identifying, analyzing, testing, and mitigating vulnerabilities in Ethereum smart contracts and decentralized finance protocols. Across 40 chapters, it progresses from EVM architecture and Solidity execution to advanced DeFi attack surfaces, automated security analysis, formal verification, real-world exploit investigations, and professional auditing practices.

The Solana MEV Playbook: Building High-Frequency Arbitrage and MEV Bots in Rust Solana moves in milliseconds. MEV moves in microseconds. If your bot is slow, someone else eats your trade. This is the technical playbook for engineers who want to build production-grade MEV and arbitrage infrastructure on Solana — in Rust, from the ground up, with real code and real architecture.

Build real smart contracts with confidence from your very first line of Solidity. This hands-on guide walks you from blockchain fundamentals to advanced security, DeFi, NFTs, DAOs and production-ready development. Packed with practical examples and proven patterns, it gives you the skills to create secure Ethereum applications that are ready for the real world.

L’intelligence artificielle peut écrire du code, mais elle ne décide pas seule de l’architecture. Apprenez pas à pas à concevoir une véritable application d’analyse Bitcoin avec Ruby on Rails, PostgreSQL et l’IA, même si vous débutez en programmation.

The future of technology is decentralized—and blockchain is at the center of this transformation.From global banks and fintech companies to healthcare organizations, supply chain enterprises, gaming platforms, governments, and Web3 startups, blockchain technology is creating entirely new career opportunities. Companies around the world are actively searching
