‍

What is Blockchain?

Blockchain is a decentralised digital ledger technology that records transactions across a network of computers in a secure and tamper-proof manner. It operates by grouping data into "blocks," which are then linked together in a chronological "chain."

‍

Each block contains a unique identifier called a hash and a reference to the previous block’s hash, ensuring that once data is added, it is nearly impossible to alter without changing all subsequent blocks. This structure provides a high level of security through cryptographic techniques and consensus mechanisms, allowing participants to trust the data without relying on a central authority. 

‍

Blockchain technology supports various applications beyond cryptocurrencies, including supply chain management, healthcare data management, financial transactions, and secure voting systems, all of which benefit from its transparency, immutability, and decentralisation.

‍

What Does a Blockchain Developer Do?

A blockchain developer specialises in creating and managing blockchain-based systems and applications. Their role encompasses designing the architecture of blockchain networks, including selecting consensus algorithms and structuring data, as well as writing and deploying smart contracts that automate transactions and enforce agreements.

‍

They develop decentralised applications (dApps) by integrating user interfaces with blockchain technology and are responsible for setting up and maintaining network nodes to ensure smooth operation. Additionally, blockchain developers focus on implementing security measures to protect against vulnerabilities and ensure compliance with regulatory standards.

‍

They continuously research advancements in blockchain technology, collaborate with other team members, and document their work to support ongoing development and maintenance.
