Study Notes

Introduction

  • Elon Musk stated a preference for being involved in the development of something, rather than just watching it happen.

Definition of Cryptocurrencies

  • Cryptocurrencies are defined as digital or virtual currencies secured using cryptography.
  • This cryptography makes counterfeiting or double-spending nearly impossible.

Bitcoin vs. Altcoins

  • Bitcoin was the first cryptocurrency, created in 2008.
  • It currently dominates the market with the largest market capitalization.
  • Altcoins are other cryptocurrencies introduced after Bitcoin.

Crypto Asset Classes

  • Crypto assets are cryptographically secured digital representations of value or contractual rights, often using distributed ledger technology.
  • These assets can be transferred, stored, or traded electronically.
  • Seven main classes exist:
    • Cryptocurrencies—like Bitcoin and Litecoin; used for payments.
    • Protocol tokens—enable decentralized apps (dApps) on a network.
    • Utility tokens—fund projects and are used with dApps (Ethereum).
    • Security tokens—represent ownership of underlying assets (e.g., stocks).
    • Stablecoins—aim for price stability, often backed by traditional currencies (USDT or USDC).

Crypto Collectibles/NFTs

  • Non-Fungible Tokens (NFTs) are unique and indivisible tokens.
  • They can be entirely virtual or linked to tangible assets (tokenization).
  • Examples of NFTs include digital artwork and virtual land within the Metaverse.

Smart Contracts

  • Smart contracts are self-executing programs that automate tasks within an agreement.
  • These contracts are trackable and irreversible once complete.
  • Key steps in smart contracts are pre-defined conditions, triggered events, execution, and settlement recorded on the blockchain.

Smart Contracts: Benefits and Limitations

  • Benefits:
    • Trust and transparency due to decentralization.
    • Enhanced security through robust encryption.
    • Increased accuracy with reduced manual errors.
    • Efficiency via automated execution, reducing costs.
  • Limitations:
    • Mistakes in smart contracts cannot be easily fixed (irreversibility).
    • Complexity often requires specialized expertise.
    • Legal recognition is not universal in all jurisdictions.
    • High execution costs can occur on busy networks for smart contracts.

Decentralized Applications (dApps)

  • dApps are software programs that run on blockchains or peer-to-peer networks.

Decentralized Autonomous Organizations (DAOs)

  • DAOs are entities without central authorities.
  • Smart contracts control voting and decision-making.
  • Holders of tokens can directly participate.

ID Management

  • Decentralized Identity (DID) management, crucial for smart contracts.
  • Allows enhanced self-sovereignty through user control over personal data.
  • Facilitates interoperability and reduces fraud through direct verification.

Zero-Knowledge Proofs (ZKPs)

  • Zero-knowledge proofs allow parties to verify information without revealing the actual information itself.
  • This enhances privacy and reduces the risk of leaks during verification.

Blockchain Layers

  • Blockchains are composed of five layers, including hardware for nodes, foundational networks, consensus networks like Bitcoin or Ethereum, scaling solutions, and application layers.

Blockchain Trilemma

  • Blockchain faces a trilemma balancing speed, decentralization, and security to satisfy all needs.

Decentralization and Protection

  • Decentralization means distributing control among multiple nodes to counter potential attacks.
  • It improves the security to protect from potential hacks like 51% attacks.

Use Cases of Blockchain

  • Blockchain applications revolutionize industries like supply chains (track goods), healthcare (patient data management), and real estate (asset tokenization).
  • Other industries using blockchain include anti-counterfeiting, epidemic tracking, financial management.
