## Cryptocurrency

<mark style="color:orange;">Cryptocurrency is a digital or virtual currency stored in a blockchain database. An unknown person or a group of people with the moniker Satoshi Nakamoto conceptualized the cryptocurrency idea and brought it to fruition by creating the first crypto, Bitcoin. A cryptocurrency is a form of payment that can be exchanged online for goods and services. Many companies have issued their currencies, often called tokens, which can be traded specifically for the good or service the company provides. Think of them as you would arcade tokens or casino chips. You'll need to exchange real currency for cryptocurrency to access the goods or services you want.</mark>

Cryptocurrencies work using a technology called the blockchain. Blockchain is a decentralized database spread across many computers that manage and record transactions. Part of the appeal of this technology is its security. Blockchain technology has no central authority; all stored blocks are connected to the chain. With this approach, nobody can change or tamper with the data. Blockchain opens the door to many possibilities with varying applications across different industries — governments, hospitals, businesses, companies, etc., all benefit from blockchain integration. The advantages of blockchain technology are innumerable.

For instance, if your health care services and data are stored on the blockchain, and you get sick while out on vacation, the doctors can easily access your health records, information about your allergies, past treatments, medication, etc. They can then treat you accordingly, even if you are unconscious or unable to speak to the doctor.

Blockchain technology has other merits when applied to food services and farm-to-table tracking. Suppose someone is allergic to certain pesticide sprays and a guardian is out shopping for food for them; they can scan the labels on the food item they intend to purchase and access data related to the product. This information will include how it was grown on the farm, the pesticides used, the method of transport, etc. This approach to food consumption could revolutionize the food industry, promote transparency, and help people make better decisions regarding the food they consume.

Dubai is one of the first countries to drive the blockchain revolution by creating the smart Dubai 2021 initiative. This program is part of the nation's move toward becoming a fully digital and paperless city powered by blockchain services. With this, Dubai can cut costs on paper manufacturing while providing better data storage systems with faster and more secure transactions.

712 million trees. 1,165 million tons of water. 78 million tons of oil are used yearly to make papers. Considering that global warming is a big issue the world is facing right now and how important trees are to the environment, blockchain could provide suitable alterantives to the felling of trees and resources required for paper manufacturing.

These examples only scratch the surface of what is possible with this technology. Experts predict that we will eventually witness a global adoption of blockchain technology cutting across different industries worldwide.
