Study Notes
Blockchain Communication and Architecture
- Blockchains can be built on various architectures that allow for inter-chain communication.
- Enhanced interactions between different blockchains improve the overall ecosystem.
Transactions per Second (TPS)
- Visa can execute up to 24,000 TPS, illustrating the scale of traditional transaction systems compared to blockchain networks.
Energy Efficiency
- Recent developments aim to make blockchains less energy-intensive, improving their sustainability.
Agenda Overview
- Organizational topics, fundamentals of Blockchain 1.0, and the concept of Blockchain 2.0 featuring smart contracts form the core learning components.
- Exploration of practical use cases in finance is also included.
Smart Contracts
- Smart contracts are coded agreements stored on the blockchain, with conditions publicly available on the ledger.
- Execution of smart contracts is triggered by specific events (e.g., date, transaction).
Legal Considerations
- A legal contract is defined as a binding agreement between competent parties.
- There is an ongoing debate on how decentralized finance impacts traditional legal definitions and frameworks.
Evolution of the Web
- The transition from Web 1.0 (information economy) to Web 2.0 (platform economy) leads to Web 3.0 (token economy) where users can not only read and write but also own assets digitally.
Blockchain Adoption
- Increased adoption of blockchain technology is anticipated, reshaping economies and industries.
Economic Impact of Blockchain
- Blockchain is considered a multiplier in economy, influenced by Metcalfe’s Law, where network value increases with user connectivity (proportional to n²).
Blockchain Trilemma
- The trilemma outlines three critical aspects: scalability, security, and decentralization, which must be balanced for effective blockchain performance.
Blockchain Layers
- Layer 0: Base architecture for platforms and development kits.
- Layer 1: Primary blockchains like Bitcoin and Ethereum, characterized by their own transaction systems.
- Layer 2: Infrastructure focused on enhancing scalability and reducing costs, often referred to as rollups.
- Layer 3: Application layer responsible for user interfaces and executing smart contracts on underlying blockchains.
