Blockchain tutorial 3: Hash

This is part 3 of the Blockchain tutorial explaining what hashes are.

In this video series different topics will be explained which will help you to understand blockchain.

Bitcoin released as open source software in 2009 is a cryptocurrency invented by Satoshi Nakamoto (unidentified person or group of persons).
After the introduction of Bitcoin many Bitcoin alternatives were created. These alternate cryptocurrencies are called Altcoins (Litecoin, Dodgecoin etc).
Bitcoin’s underlying technology is called Blockchain.
The Blockchain is a distributed decentralized incorruptible database (ledger) that records blocks of digital information. Each block contains a timestamp and a link to a previous block.

Soon people realises that there many other use cases where the Blockchain technology can be applied and not just as a cryptocurrency application.
New Blockchain platforms were created based on the Blockchain technology, one of which is called Ethereum.
Ethereum focuses on running programming code, called smart contracts, on any decentralized application.

Using the new Blockchain platforms, Blockchain technology can be used in supply chain management, healthcare, real estate, identity management, voting, internet of things, etcetera, just to name a few.
Today there is a growing interest in Blockchain not only in the financial sector but also in other sectors.

Explaining how Blockchain works is not easy and for many the Blockchain technology remains an elusive concept.
This video series tries to explain Blockchain to a large audience but from the bottom up.
Keywords often used in Blockchain conversation will be explained.
Each Blockchain video is short and to the point.

It is recommended to watch each video sequentially as I may refer to certain Blockchain topics explained earlier.

10 gedachten over “Blockchain tutorial 3: Hash”

  1. OK, it's getting deeper, but I'm still following. This is like reading an Agatha Christie's thriller– suspense is building up….

  2. For some reason I need quotes around my filenames to output hash values. Maybe because I'm using High Sierra or zsh?

  3. Thanks for showing me how to use MD5 and SHA algorithms out of the box from the terminal.

  4. How sha256 can be colision resistant if i can put infinite sign but can get only 256 bit long hashes code? Thank you for your channel is very informative.
