At its core, a blockchain is a decentralized and distributed digital ledger that records transactions across a network of computers. Each block in the chain contains a timestamp and a link to the previous block, creating a chronological and immutable record of transactions.

Importance of coding languages

Coding languages serve as the building blocks for developing applications on the blockchain. They enable developers to write smart contracts, create dApps, and interact with blockchain networks.

Popular Coding Languages

Now, let’s explore some of the key coding languages you’ll need to master to become a proficient blockchain developer.

Solidity: The language of Ethereum
