What is Blockchain?

I want to write series of articles about technologies and concepts that blockchain uses. Most of them not new and already exist for many years and was used in many different project before they was combined to one specific technology that we now calling ‘Blockchain’.

For examples of specific implementation I will be use the most popular project that contain internal turing-complete language — Ethereum.

So here is list of some core concepts that would be described later in separate articles and later linked to this list:

• Private keys
• Transactions
• Blocks
• Smart Contracts

And some of most popular use cases, except money transfer:

• ICO (ERC-20)
• NFT (ERC-721)

So if you interested in getting deeper knowledge how blockchain actually work and what you can do we that subscribe and follow updates.
