What is Block chain ?

Blockchain

The Blockchain is a secure transaction ledger database​ that is shared by all parties participating in an established, distributed network of computers. It records and stores every transaction or exchange of data that occurs in the network, essentially eliminating the need for trusted and centralized third parties. It enables entities (companies, individuals, sensors) to exchange and/or share data and information in a distributed and secure way, enabling anonymity of these entities.

Credentials Objectives
  1. Learn about Blockchain technology and its application​ across various industries
  2. Describe the differences between traditional databases and distributed ledger technology
  3. Understand core Blockchain concepts​ such as consensus, transaction processing, state databases and cryptography
  4. Explain core Blockchain values​ such as transparency, auditability, efficiency and real time data
  5. Understand how Blockchain has evolved​ from cryptocurrencies like Bitcoin to large commercial consortia such as R3 and Hyperledger
  6. Develop basic knowledge of prominent Blockchain platforms and their architectures
  7. Explain the methodologies, approaches and challenges in adopting Blockchain technology
