Module 4: Blockchain and Cryptocurrencies
This module provides a deep dive into the foundational technology of many fintech innovations: blockchain. It goes beyond the hype of cryptocurrencies to explain the concepts of decentralized ledgers, cryptographic security, and smart contracts, focusing on their potential applications in business.
- Suggested Materials:
- “Bitcoin and Cryptocurrency Technologies” by Arvind Narayanan et al. (Chapters 1-2).
- Investopedia articles on blockchain, Bitcoin, and Ethereum.
- Video explainers on how blockchain technology works.
- Checklist of Questions:
- Explain the concept of a decentralized ledger and its primary advantages over a centralized database.
- What is the difference between a public and a private blockchain?
- Discuss the potential applications of blockchain technology beyond cryptocurrency.
Answer :
- A decentralized ledger, also known as a Distributed Ledger Technology (DLT), is a secure, digital system for recording transactions and data that is replicated, shared, and synchronized across a vast network of computers (nodes) without relying on a single central authority. Eliminates the need for a trusted third party, highly secure and resistant to cyberattacks, and Immutability ensures that once data is recorded and verified, it cannot be tampered with or retroactively changed.
- A Public Blockchain is permissionless, meaning anyone can join, read the ledger, submit transactions, and participate in the consensus process (like mining or staking). They are fully decentralized and transparent. Bitcoin and Ethereum are the most famous examples. Private blockchains, on the other hand, are permissioned, meaning participation is limited. Only authorized users can join the network, and a single entity or consortium (group of organizations) controls who has access and what they can do. These blockchains are generally more centralized and are often used by companies for internal operations. Hyperledger Fabric is a common example.
- Blockchain technology, at its core, is a decentralized, immutable, and distributed ledger that can securely record any kind of data or transaction, not just financial ones. Its key features—security, transparency, and immutability—enable a wide range of applications far beyond cryptocurrency, transforming various industries.
