What is blockchain?
Definition of Blockchain
Blockchain can be described as a distributed electronic ledger that captures transactions over various computer systems. This is a decentralised platform, implying that there is no central authority controlling it. In a blockchain network, each transaction is recorded in a block that forms a chain. After the entry of information into the chain, it is extremely difficult to modify the content. The use of this technology eliminates the middleman’s role in financial dealings.
How Blockchain Works
How blockchain operates involves a computer network, known as nodes. Once there is a transaction, it is verified by the nodes.
The next step is that once the transaction is verified, it is included in the block. The block then has its own specific identification number, which is known as a hash, linking it to the previous one.
By verifying every transaction publicly, blockchain makes fraudulent activity less likely.
What are cryptocurrencies?
Cryptocurrency is an internet currency running on blockchain technology. Cryptocurrency is not governed by any government or central bank.
Individuals can use cryptocurrencies for sending payments, purchases, and investments. The transactions using cryptocurrency are faster and cheaper than those conducted using banks.
In the year 2026, cryptocurrency is also applied in gaming, online services, and ownership of digital assets.
