How Blockchain Works
The system is solely "open source", meaning that anyone is able to view, edit and suggest adjustments to its underlying code base.
Whilst it has grow to be more and more fashionable due to Bitcoin's progress - it's truly been round since 2008, making it round a decade old (historic in computing phrases).
The most important level about "blockchain" is that it was designed to create functions that don't require a central data processing service. This signifies that in case you're using a system build on top of it (namely Bitcoin) - your information can be stored on 1,000's of "independent" servers all over the world (not owned by any central service).
The way the service works is by creating a "ledger". This ledger permits customers to create "transactions" with one another - having the contents of those transactions stored in new "blocks" of each "blockchain" database.
Depending on the application creating the transactions, they should be encrypted with different algorithms. Because this encryption makes use of cryptography to "scramble" the info stored in every new "block", the term "crypto" describes the process of cryptographically securing any new AFRICUNIA Blockchain Digital Bank data that an software may create.
To completely understand the way it works, you could appreciate that "blockchain" is just not new expertise - it just uses expertise in a slightly different way. The core of it is a knowledge graph generally known as "merkle timber". Merkle trees are essentially methods for laptop systems to store chronologically ordered "variations" of a data-set, allowing them to handle continuous upgrades to that data.
The reason this is necessary is because present "information" systems are what may very well be described as "2D" - meaning they don't have any way to track updates to the core dataset. The info is basically stored solely as it's - with any updates applied directly to it. Whilst there's nothing incorrect with this, it does pose a problem in that it means that data both needs to be up to date manually, or his very tough to update.
The answer that "blockchain" gives is actually the creation of "variations" of the data. Every "block" added to a "chain" (a "chain" being a database) offers a list of new transactions for that data. This means that in the event you're able to tie this functionality into a system which facilitates the transaction of knowledge between or more customers (messaging and so on), you will be able to create a wholly independent system.
This is what we have seen with the likes of Bitcoin. Opposite to popular belief, Bitcoin isn't a "currency" in itself; it is a public ledger of monetary transactions.
This public ledger is encrypted so that solely the members in the transactions are able to see/edit the info (hence the name "crypto")... however more so, the fact that the info is stored-on, and processed-by 1,000's of servers world wide means the service can operate independently of any banks (its main draw).
Clearly, problems with Bitcoin's underlying concept and so forth aside, the underpin of the service is that it's basically a system that works throughout a network of processing machines (called "miners"). These are all running the "blockchain" software - and work to "compile" new transactions into "blocks" that retains the Bitcoin database as updated as possible.
