Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system.
A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of that transaction is added to every participant’s ledger. The decentralized database managed by multiple participants is known as Distributed Ledger Technology (DLT).
Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a hash.
This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all the distributed versions of the chain.
Blockchains such as Bitcoin and Ethereum are constantly and continually growing as blocks are being added to the chain, which significantly adds to the security of the ledger.
The prevailing issue is trust. If someone creates a new currency called the X dollar, how can we trust that they won’t give themselves a million X dollars, or steal your X dollars for themselves?
Bitcoin was designed to solve this problem by using a specific type of database called a blockchain. Most normal databases, such as an SQL database, have someone in charge who can change the entries (e.g. giving themselves a million X dollars). Blockchain is different because nobody is in charge; it’s run by the people who use it. What’s more, bitcoins can’t be faked, hacked or double spent — so people that own this money can trust that it has some value.
Now if you want to become a blockchainer, you have got to work hard. This is not a platform where you would become successful in just a couple of months. You have got to work hard for around 4–5 years to establish a proper future.

Though, graphics design is also a demanding profession. But if we see the increasing demand of video editors we can say that this can protect your future. As we know, not more that 2% of companies using video to promote their product or industry. But in social media, videos getting more than 22 times more response compare to images or texts.

So the insufficient supply of videos editors will increase the chance of a professional video editor to earn more money.
