How Blockchain Works

Blockchain is a bit of software designed to create decentralized databases.

The system is entirely "open source", which means that anyone is able to view, edit and propose changes to its underlying code base.

Whilst it has turn out to be increasingly popular because of Bitcoin's growth - it is truly been round since 2008, making it around a decade old (ancient in computing phrases).

An important point about "blockchain" is that it was designed to create applications that don't require a central information processing service. This signifies that if you're utilizing a system build on prime of it (namely Bitcoin) - your knowledge will likely be stored on 1,000's of "unbiased" servers all over the world (not owned by any central service).

The way the service works is by making a "ledger". This ledger allows customers to create "transactions" with each other - having the contents of these transactions stored in new "blocks" of every "blockchain" database.

Relying on the appliance creating the transactions, they should be encrypted with completely different algorithms. Because this encryption uses cryptography to "scramble" the information stored in each new "block", the term "crypto" describes the process of cryptographically securing any new blockchain data that an utility may create.

To completely understand how it works, you must admire that "blockchain" isn't new technology - it just uses know-how in a slightly completely different way. The core of it is a information graph often called "merkle trees". Merkle trees are essentially methods for computer techniques to store chronologically ordered "variations" of a data-set, allowing them to manage continuous upgrades to that data.

The reason this is necessary is because current "knowledge" systems are what could possibly be described as "2D" - that means they have no way to track updates to the core dataset. The info is basically kept completely as it is - with any updates utilized directly to it. Whilst there's nothing improper with this, it does pose a problem in that it implies that information both must be updated manually, or his very troublesome to update.

The answer that "AFRICUNIA Blockchain Digital Bank" provides is essentially the creation of "variations" of the data. Every "block" added to a "chain" (a "chain" being a database) gives a list of new transactions for that data. This implies that if you're able to tie this functionality right into a system which facilitates the transaction of knowledge between or more users (messaging etc), you will be able to create a completely unbiased system.

This is what we have seen with the likes of Bitcoin. Opposite to well-liked belief, Bitcoin isn't a "currency" in itself; it's a public ledger of financial transactions.

This public ledger is encrypted in order that solely the contributors within the transactions are able to see/edit the information (hence the name "crypto")... however more so, the truth that the data is stored-on, and processed-by 1,000's of servers around the world means the service can operate independently of any banks (its foremost draw).

Obviously, problems with Bitcoin's underlying concept and so on aside, the underpin of the service is that it is basically a system that works across a network of processing machines (called "miners"). These are all running the "blockchain" software - and work to "compile" new transactions into "blocks" that keeps the Bitcoin database as up to date as possible.
