Blockchain and NFT

“The blockchain is an incorruptible digital ledger of economic transactions”

Cryptocurrency is a digital or virtual coin secured by cryptography, which makes it next to impossible to counterfeit.

A cryptocurrency or “crypto” is a digital currency that can be used to buy goods and services. It uses an online ledger with strong cryptography to secure online transactions.

Much of the interest in these unregulated currencies is to trade for profit, with speculators at times driving prices skyward.

They have their own store values and are designed to use as a medium of exchange for buying goods or services.

Cryptocurrencies are decentralized, meaning that no authority regulates them.

They are built on blockchain network technology, which ensures transparency and helps track every transaction.

So, cryptocurrency does not exist in physical form and is typically not issued by a central authority.

Because cryptocurrencies do not have an underlying economic base, they are inflation-proof, but not speculation-proof.

Also, the digital structure facilitates portability across the globe and offer transparency.
