    Study Notes

    Section 10: Blockchain, Cryptocurrencies, and Smart Contracts

    • This section covers legal implications of decentralized technologies, cryptocurrency regulation, and smart contracts
    • The presentation was given by Dr. Narmin Miriyeva, PhD at ADA University on November 29, 2024

    Brief

    • Legal implications of decentralized technologies
    • Regulation of cryptocurrencies and digital assets
    • Smart contracts: enforceability and challenges
    • Definition of Decentralization: Distribution of functions, control, and information instead of centralizing them in a single entity. A hub-and-spoke model describes centralized systems; whereas decentralization is an opposite structure.
    • Centralized vs. Decentralized: Centralized systems have a single point of control (e.g., a central bank managing a currency), while decentralized systems (e.g., the internet) have multiple nodes that make up the network.
    • Bitcoin: Created as a decentralized peer-to-peer payment network utilizing blockchain technology, it avoids centralized control of banks/financial institutions. Ownership and control of the network is by the community and transactions are maintained via peer-to-peer networks.
    • Blockchain technology: Decentralized, tamper-resistant distributed ledger used to store and verify transactions
    • Benefits of Decentralization: Increased data accuracy, reduced downtime, transparency, full control by members of the system, and immutability(the data integrity).

    1.2 Types of Decentralization

    • Fully centralized: Controlled by a single central authority
    • Semi-decentralized: Controlled by multiple authorities
    • Fully decentralized: No middlemen or central authorities involved.

    1.3 Benefits and Downsides of Decentralization

    • Benefits: Trust is inherent; increased data accuracy, reduced downtime, transparency, full control, immutability.
    • Downsides: Cost; lack of consensus, lack of clarity, lack of discipline.

    1.4 What is Blockchain?

    • A tamper-proof, distributed ledger used for securely storing transactional data
    • Data stored in permanent blocks (chained) linking them cryptographically
    • Data integrity through cryptographic linking; any alteration causes a chain break
    • Verified transactions through a decentralized consensus mechanism.

    1.4.1 How Blockchain Works

    • Users initiate transactions; Network nodes validate transactions using cryptographic algorithms; blocks are formed; validated transactions pooled into the blocks; accepted blocks added permanently to the blockchain; miners use Proof of Work (PoW) or Proof of Stake (PoS) for block confirmation.

    1.4.2 Key Elements

    • Distributed Ledger: Data not stored in a single place, but on multiple computers called nodes
    • Cryptography: Secures data and assets held on the blockchain
    • Consensus Mechanism: Method for validating transactions—e.g., Proof-of-Work or Proof-of-Stake

    1.4.3 Types of Blockchain

    • Public: Open to anyone with internet access, the consensus is reached in the network
    • Private: Controlled by a single, central authority
    • Consortium (Federated): Multiple organizations control the blockchain
    • Hybrid: Combines characteristics of public and private blockchain

    1.4 Blockchain Pros and Cons

    • Pros: Equal access, censorship resistance, tamper-proof transactions, decentralized governance, and ownership of digital assets
    • Cons: Slower data processing, more cumbersome for daily transactions, high energy consumption, and high cost of transaction

    2 Regulation of Cryptocurrencies and Digital Assets

    • Need for Regulation: Cryptocurrencies face challenges like money laundering, consumer protection, and financial stability.
    • EU Perspective: Regulation to balance innovation and protection of consumers and markets.
    • Legal Issues (e.g.): Jurisdictions, Governance and documentation, technological neutrality of regulatory regime

    3 Smart Contracts

    • Definition: Self-executing programs that automate actions in blockchain transactions
    • Characteristics: Trackable, irreversible, and no need for intermediaries
    • Comparison to Traditional Contracts: Smart contracts are code that execute actions when conditions are met; however, they may not meet all the formal requirements for traditional contracts
    • Benefits: Efficiency, accuracy, immutability
    • Downsides: Permanency, human error, loopholes
    • Issues with smart contracts' legal recognition, and enforcement.
    • Smart contract disputes
    • Determining jurisdiction

    3.2 Smart Contract Pros and Cons

    • Pros: Efficiency, Accuracy, Immutability
    • Cons: Permanence, Human Factor, Loopholes
    • Legal formalities
    • Transparency
    • Auditability
    • Retrospective resolution
    • Marginal judgement
    • Craig Wright v. Kleiman Estate: Dispute over Bitcoin ownership; court ruled partly in favor of Wright but imposed damages
    • United States v. Ross Ulbricht: Case related to Silk Road (online black market). Ulbricht was convicted and sentenced to life imprisonment
    • SEC v. Ripple Labs Inc.: Case about whether XRP tokens were securities under U.S. law. The court decided partly in favor of Ripple.
