Mining is the process of adding transactions to a blockchain, which is a huge decentralized public database of existing transactions. Mining is usually done on a separate computer because it requires a faster processor, as well as more power and heat generation than normal computer operations.


Solidity is a high-level, object-oriented programming language for creating smart contracts on automated blockchain transactions.

According to its documentation, “Solidity is the language of curly braces. It is influenced by C ++, Python and JavaScript, and is designed to target the Ethereum Virtual Machine (EVM).”

If you’re new to Solidity, I wrote a beginner’s guide about it.

You can also create your own NFT collections. Ed Amazing reporter guide about it.
