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.
