  Starting with Crypto Hashes... [2] The contents includes:

  - (Crypto) Hash
  - (Crypto) Block
  - (Crypto) Block with Proof-of-Work
  - Blockchain
  - Blockchain Broken?
  - Timestamping
  - Mining, Mining, Mining
  - Bitcoin, Bitcoin, Bitcoin
  - (Crypto) Block with Transactions (Tx)
  - References / Links

  Note: The manuscript source includes many single-file ruby script samples [3]

  Happy mining and blockchaining with ruby. Cheers. Prost.

PS: Did you know? You can build online books and bookshelves with ruby -
use the jekyll machinery with octobook themes [4].
