Tutorials

Narrative routes through several subpackages at once. Every code line on these pages is run by the documentation build.

• A guided course: from fingerprints to shared history: a seven-lesson guided course with objectives, prerequisites, and checkpoints.

• Life of a payment: one payment from a private key to a block, through a fork that undoes it and the reinclusion that restores it.

• Nonces everywhere: four different “numbers used once”, and what goes wrong when each is reused.

• Hashes everywhere: six jobs SHA-256 does, and the property each one relies on.

• Who do you trust?: the assumption behind every mechanism, and the experiment where it breaks.

Worked solutions to the gallery’s exercises are in Exercises.
