def self.from_h( h )
  transactions = h['transactions'].map { |h_tx| Tx.from_h( h_tx ) }

  ## todo: use hash and transactions_hash to check integrity of block - why? why not?

  ## parse iso8601 format e.g 2017-10-05T22:26:12-04:00
  timestamp    = Time.parse( h['timestamp'] )

  self.new( h['index'],
