Field notes
The site combines sequential beginner orientation with topic-specific guides, moving from vocabulary and wallets into consensus, source code, privacy, and proof systems. Its demonstrations are deliberately non-custodial: the browser creates an ephemeral signing key, verifies a sample payment, and shows why changing the signed amount fails. The homepage also distinguishes its simplified illustrations from production networks, whose signature schemes and transaction formats differ.
