Keywords:
Theres a lot more to the blockchain than mining Bitcoin. This secure system for registering and verifying ownership and identity is perfect for supply chain logistics, health records, and other sensitive data management tasks.

 

Blockchain in Action unlocks the full potential of this revolutionary technology, showing you how to build own decentralized apps for secure applications including digital democracy, private auctions, and electronic record management.

 

Key Features

·   How blockchain differs from other distributed systems

·   Smart contract development with Ethereum and the Solidity language

·   Web UI for decentralized apps

·   Identity, privacy and security techniques

·   On-chain and off-chain data storage

 

For intermediate programmers who know the basics of object-oriented languages and have a working knowledge of JavaScript.

 

About the technology

A blockchain is a decentralized record, stored across numerous devices with no central control or authority. Copies of this shared database are constantly  reconciled  with  one  another,  and  records  are cryptographically encoded to make them unchangeable. The result is a type of database that is at once transparent and publicly accessible, and where it is impossible to falsify or alter the historic data record.

 

Bina Ramamurthy holds a Ph.D. in fault-tolerant distributed systems, and has thirty years of experience teaching cryptography, peer-to-peer networking, and distributed systems. She is the instructor and content creator for the University of Buffalo four-course specialization on blockchain technology on the Coursera MOOC platform, and the recipient of the 2019 SUNY Chancellors Award for Teaching Excellence.
