Blockchain Straight to the Point


Blockchain Straight to the Point explains why this technology is so secure, highly available and provides an overview of several of its possibilities.
From the concept of what a blockchain is, it unfolds in explaining what a digital wallet is and how it works and how encryption guarantees its security.
It parallels ledgers to explain the modus operandi of the blockchain, explaining how cryptocurrency transactions are made (Bitcoin and Ethereum), which are blocks and demonstrates why this technology has “chain of blocks” as its name.
It goes further and invites the reader to understand how the block mining process works, the types of consensus algorithm (proof of work, proof of stake, etc.) and what the threats involved in this process would be.
Here we will demonstrate the concept of distributed computing, present in EVM (Ethereum Virtual Machine), giving several examples of smart contract applications, in addition to the various types of fungible and non-fungible tokens (NFT) present in the Ethereum blockchain.
In the end, joined by the reader, in detailed step-by-step instructions, we create an ERC-20 token in the Ethereum Network to materialize all knowledge acquired.
