My private test blockchain

What is blockchain?

It is a digital record that contains all the history of transactions carried out on the network.

Which are the main objectives of this technology?

• Keep data immutable and permanent;
• Ensure secure data transactions;
• Eliminate the need for an intermediary. For example, banks in the middle of financial transactions.

In this project I'll show its main concepts:

• hash;
• blocks;
• memory pool;
• consensus algorithms and mining;
• sign a transaction;
