Block

     Within the context of cryptocurrency, a block is an immutable digital file that stores information regarding any and all activity on the network.

Each block consists of:
  – A timestamp
  – Merkle Tree Hash
  – Reference Block Height
  – Digital Signature from miners
  – All confirmed transactions

     This structure helps maintain chronological sequencing as does a page in a book.

A block also doubles as a unit to measure the length of a blockchain & as well as an alternative timestamp.
