Cryptography signifies that which is concealed or hidden. It is writing or a description in a brief manner that secretly conveys a particular intelligence or words that we may wish to communicate. Cryptography may be used as a form of clandestine communication. The art of cryptography is a legitimate form of communication that is acknowledged in the world. Encryption is a process that uses an encryption algorithm to convert a message from plaintext into ciphertext, making the message unreadable to a third party. Block ciphers operate by breaking a message into fixed block sized messages which are encrypted using the same key. The advantage with block ciphers is that a smaller block can be created from a large message. DES (Data Encryption Standard) Data Encryption Standard is basically a symmetric-key algorithm used in the encryption of data of electronic nature. The algorithm was developed in the 1970s by IBM as Continue reading

Bitcoin’s Role as an Alternative Currency System
Bitcoin fall in a broad form of monetary history. Bitcoin is a decentralized digital money that may be sent from user to user on the peer-to-peer Bitcoin network without intermediaries. Network nodes verify transactions via cryptography and are recorded in a distributed public ledger called a blockchain. A blockchain is a distributed digital database that records all cryptocurrency transactions. It is constantly expanding as completed blocks and new recordings are added. Each block includes the previous block’s cryptographic hash, a timestamp, and transaction data. Bitcoin nodes utilize the blockchain to distinguish valid transactions. Bitcoin transactions from attempts to re-spend coins that an unknown individual or organization under open-source. Bitcoin and cryptocurrency can revolutionize how people store, transfer, and create value in money. Naturally, money is believed to be a physical commodity that may be used as a medium of exchange, such as gold or silver. People consider money a unit Continue reading

Employees need to know how they can use these technologies and the results that are likely to be obtained from them. It has become vital for organisations to manage the changes in work procedures that are Continue reading
Over Dependence on Technology – Discussion
The era of inventions and discoveries began long time ago and more inventions are currently being developed as an attempt is being made to adjust into the world’s increasing competitive environment. Technological developments have been expressed in a variety of fields in the economic, social and even political aspects of life. One of the fields that have currently experienced technological developments is communication. Technologies in communication have experienced great developments in the past few decades; developments that have seen the transformation of people’s behavior and lifestyle. Significant in the latest technological developments is the introduction of the wireless world of communication. Just three decades ago, communication was characterized by elements like telephone booths, dependence on books for information and many elements of communication were more analogue. Without the wireless form of communication, communication faces the limitation of geographical distances, for instance one has to get a telephone booth in order to Continue reading
Decentralization in Cryptocurrencies
Decentralization is a defining characteristic of numerous cryptocurrencies and blockchain-based initiatives. By design, cryptocurrencies are decentralized and distributed, so there is no centralized authority or point of control. Decentralization in cryptocurrencies provides several benefits, including resistance to censorship and fraud, enhanced security, and better privacy. Decentralization carries several difficulties, particularly in terms of scalability and administration. Cryptocurrencies are a relatively young technology that is undergoing ongoing development. Therefore, there is no universal approach to Decentralization. Each project must carefully consider the involved trade-offs to develop a system that works. Adopting Decentralization in cryptocurrency makes firms more resilient and secure and gives users greater control over their finances. The policy enables investors to make independent decisions because the firm’s directives are not dependent on a specific authority. Consequently, this develops a system of trust, as the system must rely on its integrity to sustain the company’s longevity in the market. Decentralization Continue reading
