Not all blockchains are public. This post explains the real difference between public, private, and consortium blockchains — and what that tells you about who trusts whom.

A $0.10 token isn't cheaper than a $100,000 one. Price per unit tells you almost nothing — market cap and fully diluted valuation are the metrics that actually measure relative size.

The "not your keys, not your coins" maxim describes a real and important risk. But applied as a universal rule, it breaks down in three specific custody arrangements — multisig, smart contracts, and MPC wallets — each with a different failure mode worth understanding.

Yes — through three distinct mechanisms: validator slashing that destroys tokens at the protocol level, smart contract exploits in liquid staking, and custodial exchange failure. Each operates differently and requires a different response.

Smart contracts execute automatically, but legal enforceability is a separate question. This post maps how the two systems interact — jurisdiction, remedies, the mistake doctrine — and where they diverge.

A blockchain stores data, so yes — technically it's a type of database. But the dismissal misses what the structural differences actually enable, and when those differences matter.

Market cap is price times circulating supply. That's the whole formula. It tells you the aggregate value at current price — not whether that price reflects quality, safety, or return potential. Here's what the number actually means, where it falls short, and why fully diluted valuation matters more than most people realize.

Staking is marketed as passive income with minimal risk. The mechanism tells a different story. Here are the distinct risk categories — slashing, inactivity leaks, unbonding, liquid staking exposure, and inflation dynamics — mapped clearly.

Hardware wallets meaningfully reduce one specific attack vector. They don't eliminate risk. Understanding what they actually protect against — and what they don't — changes how you use them.

Quantum computers are often cited as an existential threat to Bitcoin's cryptography. The actual picture is more specific: two different threat vectors, two different timelines, and a hardware gap measured in decades, not years.

"Decentralized" is one of crypto's most overused terms. Here's what it actually measures across five distinct dimensions, how Bitcoin, Ethereum, Solana, and BNB Chain compare, and why the honest answer is more complicated than the marketing.

Miners secure Bitcoin and produce new blocks, but they don't control the protocol. Here's exactly what miners can and can't do — and what the 2017 Blocksize War proved about where power actually sits.
