Here’s how Cryptocurrency, Blockchain, Alan Turing and Julius Caesar became prestigious to human history.
The inception and historic cryptography:
Julius Caesar is the earliest use and discovery of a cipher known to human history. The Caesar Cipher was later found unhelpful in securing data and communication. Cryptography has become radically sophisticated since then.
A cipher allows any text to remain scramble for the eye of a general viewer, that the message is not intended for. The receiver may decode it using a key. In earlier times, the key could be an algorithm, a barrier grid animator, special inks or a special mechanic decipher.
Despite being a queen, Mary – Queen of Scots had to use cryptography to securely communicate on how to kill Queen Elizabeth of England in the year 1586. Her own court remained an unsafe place and encryption was immensely helpful.
The purpose of encryption is to keep the message or data safe from any person it is not intended for. This is why the key and cipher are never kept together in a traditional encryption method, yet deciphering was easy and the methods refined over time.
In the world war II, the Germans developed Enigma. Not only was the great machine helping them win the war but an entire unit under Alan Turing was using great chunks of the little national resources onto decoding it. Decoding the Enigma would have meant that any attack that Germany was planning on doing, England would have known beforehand, plan attacks and make preparations accordingly. Breaking down Enigma helped England win the war.
Alan Turing developed his own system called the Turing Machine, which remained helpful for a great chunk of the century. However, the invention of computers made the machine redundant.
Today, cryptography is the most common source of computer security for system architects. It has not only become phenomenally intricate but also branched out in various types and kinds.
Blockchain was initially developed in 1991 to be able to timestamp data on digital documents in tamper proof, permanent manner. It was rarely used until 2009, Satoshi Nakamoto dropped a white paper on the application of this technology in the creation of digital assets. He proposed the development of Bitcoin – a peer to peer digital economic system and sometime later, Bitcoin gained popularity as a platform.
Blockchain uses mathematical algorithms and is based on a particular branch of mathematics called cryptography. Letters and Alphabets (characters) are manipulated in this technique to make sure data is only used for its intended use and remains scrambled otherwise. This makes it hard to alter or meddle with.
The underlying cryptography in the blockchain systems improves transparency and speed of data transfer – making it high suitably for sensitive data transfer with the added benefit of high accountability in real time. Cryptography finds its origin in the ancient Egyptian times of Julius Caesar. The contemporary cryptography is much more sophisticated.
