Day 1: Introduction to blockchain

• Fundamental concepts: Presentation of the key notions of blockchain, including decentralisation, consensus and cryptography. Discussion of the importance of these concepts in data security and integrity.
• Types of blockchains: Exploration of the different types of blockchains, including public, private, and permissioned blockchains, and their respective use cases.

Day 2: Cryptocurrencies and Ecosystems

• Understanding cryptocurrencies : Analysis of the main cryptocurrencies such as Bitcoin and Ethereum, their operating mechanisms, and their impact on the digital economy.
• Consensus mechanisms: Study of the different consensus mechanisms, including Proof of Work and Proof of Stake, including their advantages and disadvantages.

Day 3: Developing Intelligent Contracts

• Introduction to Solidity: Familiarisation with Solidity, the programming language used to write smart contracts on Ethereum. Presentation of the basic concepts and syntax.
• Creating, deploying and testing smart contracts: Practical steps for developing, deploying and testing a smart contract, including the use of tools such as Remix IDE.

Day 4: Developing Decentralised Applications (dApps)

• Architecture of a dApp: Understanding the components of a decentralised application, including the user interface, smart contracts and the underlying blockchain.
• Use of libraries and frameworks: Introduction to libraries such as Web3.js and frameworks such as Truffle, which facilitate the development of decentralised applications.
   

Day 5: Security of Blockchain Applications

• Identification of common vulnerabilities : Analysis of vulnerabilities specific to smart contracts and dApps, such as reentrancy attacks and key management issues.
• Best practices for securing smart contracts and dApps: Discussion of strategies for strengthening the security of blockchain applications, including code auditing and the use of unit tests.
• Solutions for interoperability between blockchains: Exploration of methods to enable different blockchains to communicate with each other, such as cross-chain exchange protocols.
• Techniques for improving application performance and scalability: Discussion of scalability challenges in public blockchains and potential solutions, such as layer 2 solutions.
• Development of a complete dApp project: Practical application of the skills acquired by developing a functional dApp in groups or individually.
• Analysis of real cases of successful blockchain applications: In-depth study of concrete examples of blockchain applications that have had a significant impact in various sectors.
• This programme offers comprehensive training in blockchain development, combining theory, practice and case studies to effectively prepare participants to become competent blockchain developers.
