A blockchain is, in the simplest of terms, a time-stamped series of immutable records of data that is managed by a cluster of computers not owned by any single entity. Each of these blocks of data (i.e. block) is secured and bound to each other using cryptographic principles (i.e. chain).
What is Blockchain technology and how does it work?
Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a ‘digital ledger.
What is Blockchain technology in simple terms?
A blockchain is a digital record of transactions. The name comes from its structure, in which individual records, called blocks, are linked together in single list, called a chain. Blockchains are used for recording transactions made with cryptocurrencies, such as Bitcoin, and have many other applications.
What does a Blockchain developer do?
Blockchain software developers create Dapps or decentralized applications. They are responsible for the front-end as well as back-end development of Dapps. They also supervise the stack that runs the Dapps.
How does Blockchain consensus work?
Essentially, the consensus protocol makes sure that every new block that is added to the Blockchain is the one and only version of the truth that is agreed upon by all the nodes in the Blockchain.

Why consensus is used in Blockchain?
A consensus mechanism is a fault-tolerant mechanism that is used in computer and blockchain systems to achieve the necessary agreement on a single data value or a single state of the network among distributed processes or multi-agent systems, such as with cryptocurrencies.
What are the two major Blockchain consensus mechanisms?
Most blockchain projects use one of the three currently most common consensus algorithms: Proof of Work (PoW), Proof of Stake (PoS) or Delegated Proof of Stake (DPoS). All these mechanisms aim at ensuring that all participants dispose of identical copies of the distributed database files.
