What is a Blockchain Technology?

A blockchain is a distributed database or ledger that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. It is a growing list of records, called blocks, that are securely linked together using cryptography. Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger, where nodes collectively adhere to a protocol to communicate and validate new blocks.

Robotics and ahead…

The Wave of the World; Robotics and Its way forward Robotics is that the design, repair, and maintenance of robots. Applications include drone deliveries, mechanical welding arms, self-driving cars, autonomous machines, artificial intelligence-based sorting mechanisms etc.


The root word for ‘Robot’ is a Slavonic word called ‘robota’ which means labor or servant. Indeed, robots (as a worker) are intended to reduce the effort time of humans — big companies like Tesla, Google, and Meta heavily depend on modern innovations.


Robots are designed to make human life simpler, specifically to make labor easier. A robot, according to the Webster Dictionary, is “an automated apparatus that performs duties typically attributed to people or a machine in the guise of a person.”

robot can now perform a routine colonoscopy. What is the future of surgical robots?

Over the turn of the century, there have been huge developments in science and technology. And one of the major development has taken place in Robotics. Robots have developed from doing some heavy and repeated tasks to performing detailed tasks with high precision. Robots are used in numerous fields, ranging from automobiles, industry, and Service to research and medicine.

Journey of Robotics

One of the first instances of a mechanical device built to regularly carry out a particular physical task occurred around 3000 B.C. In 400 B.C., the Archytas of Tarentum, inventor of the pulley and the screw, also invented a wooden pigeon that could fly. Similarly, In the first century A.D., Petronius Arbiter made a doll that could move like a human being. Giovanni Torriani created a wooden robot that could fetch the Emperor's daily bread from the store in 1557.
