It is not yet ready for learning. +The foundation of Bitcoin is the ability to protect the transactions, something that's done with a simple scripting language. + ## Know the Parts of the Cryptographic Puzzle As described in [Chapter 1](1_0_Introducing_Bitcoin.md), the funds in each Bitcoin transaction are locked with a cryptographic puzzle. To be precise, we said that Bitcoin is made up of "a sequence of atomic transactions: each of which is enabled by the sender with the solution to a cryptographic puzzle that is stored as a script; each of which is locked for the recipient with a new cryptographic puzzle that is stored as a script". Those scripts, that lock transactions and that unlock transactions, are written in Bitcoin Script.
