Disrupting industries – Banking,Financial Services,E-sports,Payments,Gaming,Remittances,Data Storage etc.
The one word that is coming into the limelight is the…blockchain…
You’ve heard about the Blockchain and that it’s the technology that cryptocurrencies is based on, with the potential to revolutionize many industries.
In a nutshell, a blockchain is an open, distributed database – essentially, a computer file for storing information (data). The name comes from its structure: the file is made up of blocks of data, and each block is linked to the previous block, forming a chain. Each block contains data (such as transaction records), plus a record of when that block was edited or created.
Here’s an example:
- Rihanna wants to send money to Brittany Spears.
- The transaction is represented online as a block. (Think for instance about a data packet – when data has to be transmitted, say you’re making a call, it is broken down into similar structures of data before transmission, called packets, which are reassembled to the original data chunk once they reach their destination. A packet is a basic unit of communication over a digital network. A packet is also called a datagram, a segment, a block, a cell or a frame, depending on the protocol used for the transmission of data.)
- The block is stored in a shared ledger that keeps record of all the transactions that take placed in a peer-to-peer network of computers.
Here is an analogy for you to visualize: “Picture a spreadsheet that is duplicated thousands of times across a network of computers. Then imagine that this network is designed to regularly update this spreadsheet and you have a basic understanding of the blockchain.”
- The information in the ledger is open for anyone and everyone to see. Also, all the information (blocks of data) which is transferred via the blockchain is encrypted and every occurrence recorded, meaning it cannot be altered. In turn, encrypted information can be shared across multiple providers without the risk of a privacy breach.
- Hence, anything that is built on the blockchain is by its very nature transparent and everyone involved is accountable for their actions.
- Getting back to our example, the network approves the transaction. (Importantly, the network is open-source and decentralized, which means it is not controlled by anyone central, certifying authority)
- The block is added to the existing chain.
- The transaction is complete.
Blockchain can be used for much more than the currency though, almost any kind of data can be shared (distributed) on a blockchain –– openly, transparently and unalterable.
Of course, while blockchain sounds great, it can be tricky to understand it’s practical uses in real life.
