Welcome to What is BlockChain, if you have not heard of BlockChain theses’ mini FAQ’s will get you started with the Technology and all the BlockChain protocol promise.
First a little bit about me I like to call myself a Tech Evangelist and a Serial Online Entrepreneur, I have been working with technologies for over 18 years.
I started out with Novell Netware, OS2 then moved on to Lotus Notes(Messaging Platform) to coding in Java and Javascript. Today I am a Certified Cloud Architect/Devops Engineer that is how I make a study living and I enjoy doing what I do. But there was always something missing in my tech career, so that is when I started a career in Digital Marketing.
Enough about me you are reading this post to find out what is BlockChain and why should you be paying attention to this technology. Simply put a BlockChain is a Decentralized Database. Yes I know more techie stuff, but if you are familiar with MySql or lets so MS Acess those are centralized databases that means that every client/computer would connect to the one source to get data. BlockChain on the other hand is Decentralized there is no one owner of the database for simplicity sake the data is Decentralized across multiple nodes in fact you can be running the BlockChain Database on your computer.
Wikipedia says
block chain[4][5] – is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a timestamp and a link to a previous block. A blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. By design, blockchains are inherently resistant to modification of the data. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. Functionally, a blockchain can serve as "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. The ledger itself can also be programmed to trigger transactions automatically."[7]
