Study Notes

Blockchain Overview

Blockchain gained significant attention in 2017, marking its emergence beyond the initial concept of Bitcoin (2009).
Functions as a distributed digital ledger across a network of computers, enhancing transaction transparency and security.
Ethereum launched in 2015, enabling features like smart contracts and decentralized applications, as a notable blockchain platform.
Despite decreasing hype, blockchain technology continues to see increasing usage and evolution as an emerging technology.

Key Concepts

Blockchain Technology: An incorruptible digital ledger that can record any value, beyond just financial transactions.
Distributed Ledger (DL): A database stored across multiple locations or participants, ensuring data is verified by all nodes.
Immutability: Blockchain’s design prevents tampering, providing a reliable source of truth in data sets.
Distributed Ledger Technology (DLT): Encompasses blockchain but can exist without it; blockchain is a specific type of DLT.

Blockchain Typology

Public Blockchain: Open to anyone (permissionless).
Private Blockchain: Restricted to single organization participation (permissioned).
Consortium Blockchain: Involves multiple organizations (permissioned).
Comprised of five design elements that integrate existing ideas into a secure digital ledger.

Evolution of Blockchain

Blockchain 1.0 (2009): Bitcoin introduced to validate transactions and prevent double spending.
Cryptocurrency Impact: Over 20,000 cryptocurrencies generated, with values fluctuating (Bitcoin peaked at nearly $69,000 in March 2024).
Blockchain 2.0 (2015): Ethereum expanded blockchain uses for applications, data storage, and smart contracts using Solidity programming language.
Smart contracts automate terms without third-party involvement, applicable in diverse fields (e.g., supply chain, voting).

Blockchain Challenges and Solutions

Scalability and Interoperability: Initial applications faced limitations; new advancements address these issues to support complex decentralized applications.
Blockchain 3.0: Enhancements in privacy and governance, promoting interoperability, and offering Blockchain-as-a-Service (BaaS) via vendors like AWS and Microsoft.

Legislative Context

Legislative frameworks lag behind technology, with the Deploying American Blockchains Act of 2023 introduced in Congress to boost U.S. competitiveness in blockchain technology.
Legal cases primarily revolve around the classification of cryptocurrencies (commodity vs. security), influencing regulatory frameworks by entities like the SEC.

International Standards

Several ISO documents related to blockchain and distributed ledger technologies are available, with ongoing publications that may interest records and information management (RIM) professionals.

Use Cases

Supply Chain Management: Blockchain enhances transparency, traceability, and accountability in logistics.
Healthcare: Blockchain-based systems empower patients over their health data with controlled access.
Sector Applications: Increasing integration of blockchain in government, finance, cybersecurity, and media, with potential advancements in AI for enhanced data insights and patient care.
