Zero-Knowledge Proof (ZKP)

A way for two parties to verify information without revealing what the information is.

Blockchain Layer 1

The foundational blockchain layer that maintains consensus among participants, e.g., Bitcoin or Ethereum.

Blockchain Layer 2

Layer that improves the scalability of Blockchain, e.g., Polygon, allowing faster and cheaper transactions compared to the base layer.

Blockchain Trilemma

The challenge of balancing scalability, decentralization, and security in a blockchain system.

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.
