Blockchain -What You Should Know

Blockchain is an especially promising and revolutionary technology in the world today as many businesses and individuals have invested and benefitted so much from it.

What then is Blockchain, and what makes it so exciting and beneficial? Blockchain is a specific form or subset of distributed ledger technologies, which constructs a chronological chain of blocks, hence the name, “blockchain”.

A block refers to a set of transactions that is bundled together and added to the chain at the same time. A blockchain is a peer-to-peer distributed ledger, forged by consensus, combined with a system for smart contracts and other assistive technologies.

Together, these can be used to build a new generation of transactional applications that establish trust, accountability, and transparency at their core.

The reason Blockchain has gained so much admiration is because of the following characteristics:

1. Decentralization: It is not owned by a single entity; hence it is decentralized.

2. Transparency: The blockchain is transparent so one can track the data if they want to.

3. Immutability: Immutability, with respect to blockchain, means that once something has been entered into the blockchain, it cannot be tampered with.

4. The data is cryptographically stored inside.

Sequel to the aforementioned characteristics, what makes the Blockchain Technology so beneficial?

i). Reduction in systemic r isk : because blockchainbased transactions require pre- funding of a trade, credit and liquidity risk would be practically eliminated.

ii). Cutting out the Middlemen: A key advantage to blockchain technology is cutting out the middleman. In effect, because all transactions on a blockchain are validated by the community based on a mathematical probability, the requirement of a trusted intermediary is unnecessary. Blockchain would allow you to have a decentralised stock exchange, without the need for a brokerage, clearing house, or settlement process.

iii). Higher liquidity: Blockchain can reduce the inefficiencies through automation, which also leads to reduction in cost and thus lowering entry barriers resulting into increased market base.
