Cryptocurrency Fundamentals
Overview
The cryptocurrency notes focus on the mechanisms that let a decentralized monetary system function without a central authority. The recurring themes are consensus, incentives, validation, and ownership transfer.
Core Areas
Shared Ledger and Ownership
Cryptocurrency systems maintain a shared history of transactions and use cryptographic rules to determine who owns what.
Consensus Under Faults
Public blockchains must maintain agreement despite delay, failure, and potentially malicious behavior. This is where distributed consensus becomes essential.
Incentives and Mining
The notes strongly connect security to economics:
- block rewards
- transaction fees
- competition among block producers
- Proof of Work as a scarce-resource mechanism
Trade-Offs
The same mechanisms that make open consensus possible also introduce cost, latency, and scaling limits.
Relationships
- Distributed Consensus — agreement problem at the heart of cryptocurrency networks
- Proof of Work — major mechanism for selecting block producers and securing the chain
- Blockchain & Web3 — broader ecosystem context
- Ethereum Development — application-layer development built on top of similar underlying blockchain ideas
