In this blog, we’ll describe who is a blockchain developer, explain blockchain developer skills, and will teach you how to become a Blockchain Developer along with the salary one can expect in this field.
What is Blockchain Technology?
Blockchain technology is a distributed ledger system that enables secure, transparent, and tamper-resistant transactions without the need for intermediaries such as banks or government institutions. In a blockchain network, transactions are verified and recorded by a decentralized network of nodes, which ensures that no single entity can alter the data or manipulate the network.
The technology is based on cryptography, which ensures that the data stored on the blockchain is secure and cannot be accessed or altered without the appropriate keys. Each transaction on the blockchain is linked to the previous one in a chain, forming a secure and immutable record of all transactions that have taken place.
