 === Block Header
 
-The block header consists of three sets of block metadata. First, there is a reference to a previous block hash, which connects this block to the previous block in the blockchain. The second set of metadata, namely the _difficulty_, _timestamp_, and _nonce_, relate to the mining competition, as detailed in <<mining>>. The third piece of metadata is the merkle tree root, a data structure used to efficiently summarize all the transactions in the block. <<Table 7-2>> describes the structure of a block header.
