Minimal investment sizes.

Blockchain Developer's Guide will show you how to create distributed blockchain applications which do not depend on a central server or datacenter. Starting with the basic principles of blockchain architecture exploring cryptography, you will then study consensus protocols, initial coin offerings, crypto-mining, DApp deployment, Ethereum.
