The Tour

The 1st Edition covered evolution of trade and money over the millennia from barter to fiat with values by sovereign decree, to cryptocurrencies and blockchains that bypass banks. The 2nd Edition goes beyond blockchains to distributed ledger technologies that are green (fast, fee-less and miner-less) for the future era of IOT, AI and quantum computing. The material can be used for self-education and STEM training in schools, universities and on-the-job.
