What is Bitcoin?

In 2009, an unknown programmer by the name of Satoshi Nakamoto put forward a whitepaper that proposed a creation of new form of digital currency - cryptocurrency. Cryptocurrency functions the same way as regular currencies do in that its used as a means of exchange, unit of account and a store of value. Cryptocurrency, just like other resources, has some demand for it, and subsequently a market price. The significant difference is Bitcoin’s intangibility - there is no bank-issued notes or papers - meaning that rather being used in hand-to-hand transactions, Bitcoins are stored and exchanged digitally within a decentralized, peer-to-peer network. The original Bitcoin software developed by Satoshi Nakamoto was released under the MIT license. Most client software, derived or "from scratch", also use open source licensing. Bitcoin is one of the first successful implementations of a distributed crypto-currency, described in part in 1998 by Wei Dai on the cypherpunks mailing list. Building →

Genetically Modified Food or Crops

Genetic Modification Genetic modification refers to techniques used to manipulate the genetic composition of an organism by adding specific useful genes. A gene is a sequence of DNA that contains information that determines a particular characteristic/trait. All organisms have DNA (genes). Genes are located in chromosomes. Genes are units of inheritance that are passed from one generation to the next and provide instructions for development and function of the organism. Crops that are developed through genetic modification are referred to as genetically modified (GM) crops, transgenic crops or genetically engineered (GE) crops. Over the last 30 years, the field of genetic engineering has developed rapidly due to the greater understanding of deoxyribonucleic acid (DNA) as the chemical double helix code from which genes are made. The term genetic engineering is used to describe the process by which the genetic makeup of an organism can be altered using “recombinant DNA technology.” This →
