Importance of the anchor block

Stacks uses the Bitcoin blockchain only as a reliable storage and broadcast medium for recording the set of all Stacks blocks ever produced, as well as the parent/child linkages between them. The state of the system settles on Bitcoin — the act of creating a new Stacks block entails sending a well-formed Bitcoin transaction that records the hash of a Stacks block and where it attaches to the blockchain. Settling the system on Bitcoin grants Stacks novel security properties not seen in other blockchains — it leverages the security of Bitcoin to guarantee that all Stacks forks are public, and to help bootstrapping Stacks nodes identify the canonical Stacks fork and find Stacks blocks they have not yet downloaded.
