Chapter 12
Bitcoin vs Ethereum
Bitcoin and Ethereum are both blockchains, but they optimize for different goals. Bitcoin is conservative and money-focused. Ethereum is programmable and designed to support a much wider range of on-chain applications.
That difference affects everything from how upgrades are approached to what users expect the chain to do. Comparing the two directly is more useful than talking about Bitcoin versus a vague category of "altcoins."
Bitcoin supporters often see simplicity as a security feature. Ethereum supporters often see programmability as the reason blockchains are broadly useful. Both perspectives are internally coherent once you understand the design target.
For a student, the key lesson is not to flatten them into the same category. Bitcoin and Ethereum solve overlapping problems, but they express very different philosophies about what a blockchain should prioritize.
