Study Notes
Introduction to Blockchain Applications
- Elon Musk expressed interest in blockchain technology
- Cryptocurrencies are digital or virtual currencies secured by cryptography, making counterfeiting and double-spending nearly impossible.
Bitcoin vs. Altcoins
- Bitcoin was the first cryptocurrency, created in 2008, and currently holds the largest market capitalization.
- Altcoins are other cryptocurrencies created after Bitcoin.
Crypto Asset Classes
- Crypto assets are digital representations of value or contractual rights.
- They use distributed ledger technology enabling transfer, storage, and trading.
- Seven key types of crypto assets: Cryptocurrencies, protocol tokens, utility tokens, security tokens, stablecoins, crypto collectibles/NFTs, and natural asset tokens.
Cryptocurrencies
- Designed for making payments mimicking traditional currencies like Bitcoin, Litecoin.
- Protocol tokens facilitate decentralized applications and resources for managing and deploying them.
- Utility tokens are employed to fund and operate applications, often in Initial Coin Offerings (ICOs).
- Security tokens represent ownership of real-world assets like stocks, bonds, or real estate, requiring regulatory approval.
- Stablecoins are designed to maintain a fixed value, pegged to a traditional currency like the US dollar or Euro (e.g., USDT, USDC, DAI), enhancing cryptocurrency market efficiency.
Crypto Collectibles/NFTs
- NFTs are unique, non-fungible tokens.
- They can represent virtual or real-world assets.
- Examples include digital artwork, virtual land, and real estate.
Smart Contracts
- Smart contracts are self-executing programs that automate agreements in a transparent and irreversible manner.
- Main steps involve pre-defined terms, execution triggered by events (e.g., conditions met), and recorded execution within a blockchain.
- Key benefits include trust, security, accuracy, efficiency, and immutability.
- Limitations include irreversibility, complexity, potential legal hurdles, and high execution costs during busy periods.
Decentralized Applications (dApps)
- dApps are software programs running on blockchain or peer-to-peer networks.
- These applications are independent from a central server.
Decentralized Autonomous Organizations (DAOs)
- DAOs are entities governed by smart contracts, enabling token holders to participate in decision-making and token distribution without a central authority.
- ID management is key for efficient smart contract execution.
Decentralised Identity (DID) Management
- DID management allows users to control their personal data.
- Self-sovereignty is a key principle, empowering users to manage and verify identity with ease and transparency, reducing fraud and breaches.
Zero-Knowledge Proofs (ZKP)
- ZKPs enable parties to verify information without revealing the specific data.
- Advantages include higher privacy, enhanced security and reduced verification risks.
Blockchain Layers
- Blockchain consists of five layers: hardware, layer 0, layer 1, layer 2, and the application layer.
- Foundational blockchain networks or consensus-based protocols are included in layer 0.
- Different layer 1 networks handle consensus while layer 2 enhances scalability in these systems.
- Application layer hosts various dApps.
Blockchain Trilemma
- The trilemma refers to the balance between scalability, decentralization, and security in blockchain technology.
- Achieving better scalability while preserving decentralization and security is a central concern.
Blockchain Use Cases
- Applications span a wide range of industries including supply chain management, healthcare, real estate and financial services.
- The blockchain revolution alters finance markets by introducing transparency, efficiency and security, thereby reducing risks and fostering greater trust and efficiency.
