What is blockchain programming?

Naturally, blockchain programming is at the core of blockchains. As the name might suggest, blockchain technology encases information in chains of blocks. Arguably the most well-known example of a blockchain is the Bitcoin blockchain. The Bitcoin blockchain creates new transaction blocks approximately every 10 minutes.

Why is blockchain a decentralized technology?

Blockchain is known as a decentralized technology since data and authority are shared equally among everybody in the network. It differs from centralized applications where the company owns the data, and the consumers just hope their data isn’t misused.

By its very nature, blockchain acts as a safeguard against tampering and system failure. If one node on a network gets hacked and someone changes or deletes transaction data on that computer, the other nodes on the network will reject the corrupted record because it doesn't match their copies of the ledger.

First, create a directory called intro_to_blockchain. Then open the directory in a terminal. Run the following command and hit enter for all the prompts to initialize the project: We will use the blockchain.js file to write the code that emulates how blockchain works and use test.js to test the code and see the result.
