The basic idea of decentralization is to distribute the control and authority to the peripheries of an organization instead of one central body being in full control of the organization.   The benefits for organizations in following decentralization are: increased efficiency, faster decision making, better motivation, and a reduced burden on top management.   Decentralization […]

The CAP theorem, also known as Brewer’s theorem, was introduced by Eric Brewer in 1998 as a conjecture. It states that any distributed system cannot have consistency, availability, and partition tolerance simultaneously.   Consistency is a property that ensures that all nodes in a distributed system have a single, current, and identical copy of the […]

Consensus is a process of achieving agreement between distrusting nodes on the final state of data. To achieve consensus, different algorithms are used. The process of attaining agreement on a common state or value among multiple nodes despite the failure of some nodes is known as distributed consensus.   Consensus is the backbone of a […]

In this article we will discuss different types of blockchain based on its evolution and usage. The categorization of blockchains is illustrated in the figure below:   Distributed Ledgers A distributed ledger is a shared database. All blockchains technically fall under distributed ledgers. But, all distributed ledgers are not blockchains. A critical difference between a […]

In this article we will learn the basic concepts of blockchain technology like what is a blockchain? the blockchain architecture and how does a blockchain work?   In 2008, a groundbreaking paper, entitled Bitcoin: A Peer-to-Peer Electronic Cash System, was written on the topic of peer-to-peer e-cash under the pseudonym of Satoshi Nakamoto. It introduced […]

Blockchain was introduced with the invention of Bitcoin in 2008. Its practical implementation then occurred in 2009. We will look at a chronological order of early history and computer networks and how they evolved and contributed to the development of Bitcoin in 2008. The order of events is: 1960s – Invention of computer networks 1969 […]

The emergence of Bitcoin in 2008, introduced to the world a new technology called blockchain which promised to revolutionize the entire society. Blockchain is the technology behind the success of Bitcoin.   Blockchain is a technology that has an impact on current technologies and has the ability to transform them at a fundamental level.   […]
