-=== Block Identifiers—Block Header Hash and Block Height
+=== Block Identifiers: Block Header Hash and Block Height

 The primary identifier of a block is its cryptographic hash, a digital fingerprint, made by hashing the block header twice through the SHA256 algorithm. The resulting 32-byte hash, is called the _block hash_ but is more accurately the _block header hash_, because only the block header is used to compute it. For example, the block hash of the first bitcoin block ever created is +000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f+. The block hash identifies a block uniquely and unambiguously and can be independently derived by any node by simply hashing the block header.
