A blockchain developer is a type of software developer who works with blockchain technology. Our guide will walk you through what it is, how it's used and its history. The "blocks" in blockchain are chunks of data stored together. Initially created as a platform for supporting Bitcoin, Blockchain is demonstrating a level of versatility and security that has made many sectors of business and government take notice and begin putting it to their use. Blockchain definition is - a digital database containing information (such as records of financial transactions) that can be simultaneously used and shared within a large decentralized, publicly accessible network; also : the technology used to create such a database. Many times, blockchain developers are working with these interfaces for testing and development work which requires complete control of the node. Let me try and shed some light on it. “A blockchain developer is a developer that takes care of optimizing and developing blockchain-related dApps, smart contracts, protocols, and architecture.” It is a responsible position which requires attention to detail, knowledge, and ability to overcome challenges. Blockchain technology is poised to revolutionize the way the digital world handles data and does business. Blockchain technology is most simply defined as a decentralized, distributed ledger that records the provenance of a digital asset. Development Alternatives Incorporated (DAI) is also looking into how blockchain technology can be used in electronic medical records, which are becoming more common around the world.

In December of 2018, a report by LinkedIn showed that “Blockchain Developer” was the most rapidly growing emerging job in the United States.

Though a relatively recent technology, organizations are actively seeking Blockchain professionals. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree).The timestamp proves that the transaction data existed when the block was published in order to get into its hash. I have over 2+ Years of experience in blockchain development mostly on the ethereum blockchain, building cryptocurrencies, erc20 tokens, stable coins, rebase tokens, defi dapps, decentralized exchange, decentralized donation platform, and much more.
