Digital Assets

Handles crypto fundamentals, DeFi mechanics, and on-chain metrics when you're analyzing digital assets. Covers blockchain consensus mechanisms (PoW vs PoS), staking yields, impermanent loss calculations for liquidity pools, and valuation metrics like NVT ratio. Works through the math on AMM pricing, real vs nominal staking returns, and LP losses from price divergence. Useful when you need to reason about validator economics, DeFi protocol risks, or custody tradeoffs. The worked examples walk through actual calculations, which helps when you're sanity-checking yield claims or explaining why that 20% APY might not mean what people think it means.

Blockchain Fundamentals

A distributed ledger maintained by a network of nodes. Transactions are grouped into blocks, cryptographically linked in sequence. Immutability comes from the chain structure — altering any block requires recomputing all subsequent blocks. Consensus mechanisms determine how the network agrees on the valid state of the ledger.

Consensus Mechanisms

Proof of Work (PoW): Miners compete to solve computational puzzles. The winner adds the next block and earns a reward. High energy consumption but battle-tested security (Bitcoin). Security scales with hash rate.

Proof of Stake (PoS): Validators lock up tokens as collateral ("stake"). Block proposers are selected based on stake weight. Slashing penalizes malicious behavior. Far more energy-efficient than PoW. Ethereum transitioned to PoS in September 2022.
