Last time i was able to learn and discuss the main types of architectures in blockchain and was able to narrow it down to their best use case.

Day 3 is about knowing what centralisation is all about since it seems to be something i clearly do not understand very well. According to my random research, i was able to put down this:

Centralisation is a system that involves a third party or central control in processing an information. In my case i'd say they are authorities that has access to our data with or without permission. Example is the popular social platform.

Also it can be broken down to: where an organization is in charge of the decision making with limited number of people.

Just like i discussed about types of blockchain architecture, there are some main key components of blockchain architecture.

• Blocks

• Transactions

• Consensus

Future me(thinking...): but i don't understand why always the blocks, and besides who doesn't know what transaction is all about as it is our day to day activities when we do business, and for consensus i have no idea what it is.

Well my present self is about to find out (LOL).

Till day 4.
