What is Blockchain?

If it’s offline how can you distribute it to the public for verification?

The essence of blockchain technology is a publicly distributed ledger which is why you can’t have an offline blockchain.

The Internet makes possible two or more components to communicate with each other by removing the dependence on wires.

Blockchain is a peer-to-peer system for transferring information.

For an NFT to be traded is necessary a blockchain connected to the Internet.

Without the internet, there is no connection to the blockchain to validate the transaction.

We all know that the internet is one of the most influential inventions in human history.

In the Web1 and Web2, the internet has made it possible to order a book, a hotel room, sell art, watch your favorite television shows, or shop for anything without having to leave your home.

Blockchain technology represents another technological innovation that has the potential to revolutionize the world.

One of the entities in a blockchain transaction is required to have an internet connection for transaction authentication purposes.

Once a transaction is validated successfully, it is transmitted to all nodes that are linked to the system.

This implies that a valid blockchain transaction requires all nodes within the network to receive and store the details of the transaction in question.

Then the internet is crucial for conducting transactions on the blockchain.

But, dependence on the internet is becoming a critical concern for blockchain developers.
