Before discussing the intersection of blockchain technology and COVID and Bill Gates , it is likely helpful to start with a simple understanding of what blockchain technology is, and how its application is conceived. Blockchain began in as an open source project. The community that drove the development of the technology subsequently participated in its evolution through various iterations of the system, modifying the original code and tweaking it for other, wider, and more diverse applications. This wide accessibility of blockchain, reflected through its publicly accessible networks and peer-to-peer operability, is the hallmark of a system that epitomizes trust for its users and the data it produces.

Blockchain: The Backbone Of Digital Supply Chains


In little over a decade, bitcoin has risen from a fringe technology popular with cryptographers, to the world's ninth most valuable asset by market cap. The cryptocurrency 's dramatic ascent has created millionaires, reimagined money, and launched a multi-billion dollar industry inspired by its revolutionary decentralised technology. But it has also brought with it some unwanted side effects.

The computing power required to support bitcoin's underlying network now requires nearly as much energy as the entire country of Argentina, leading to criticism about its environmental footprint. Analysis by the University of Cambridge suggests the bitcoin network uses more than terawatt-hours TWh annually, which would rank it in the top 30 electricity consumers worldwide if it were a country.

Concerns about bitcoin's energy demands have been around since the very beginning, with crypto pioneer Hal Finney tweeting about potential future CO2 emissions on 27 January — just two weeks after receiving the first ever bitcoin transaction from the cryptocurrency's pseudonymous creator Satoshi Nakamoto.

The amount of energy bitcoin's network consumes did not rise to serious prominence until , when a major price rally drastically pushed up its energy needs to the level of a small country.

As the market cooled off in the years following, so did the energy demands, but the latest all-time high hit this week is more than double that of three and a half years ago. And this time its energy requirements are even greater. Bitcoin's environmental impact is exacerbated by the fact that a majority of miners are based in China, where over two thirds of power is from coal.

The mining process required to generate new units of the cryptocurrency involves solving complex but arbitrary mathematical equations, which currently requires vast amounts of computer processing power.

Bitcoin miners therefore gravitate to where electricity is cheapest, meaning the fundamental issue is not with bitcoin but with a lack of cheap renewable energy production. Fortunately, there are solutions being put in place, with some eco-friendly mining facilities already operating at a massive scale.

In Iceland and Norway, where nearly per cent of all energy production is renewable, cryptocurrency miners are taking advantage of cheap hydro-electric and geothermal energy to power their machines. The low temperatures in the countries also help reduce costs by cooling the computer servers naturally. Last year, the University of Cambridge's third Global Cryptoasset Benchmarking Study found that 76 per cent of cryptocurrency miners use electricity from renewable sources in their operations. This figure was up from 60 per cent from the same benchmarking study in This trend is expected to continue, according to projections from the International Renewable Energy Agency, which reported last year that renewable energy sources are increasingly more cost-efficient than fossil fuels.

The gold mining industry consumes million GigaJoules worth of electricity annually. I personally believe climate change is one of the most important issues in our world today, but people who say bitcoin will lead to even more environmental destruction don't understand that bitcoin is actually acting as an accelerant to helping our environment.

Alternative cryptocurrencies have also sought to solve bitcoin's current environmental issues by altering the underpinning technology in order for it to require less power. One of these is Cardano, which Hoskinson claims is 4 million times more energy efficient than bitcoin thanks to its 'Proof-of-Stake' blockchain that validates transactions based on how many coins are held by a network participant rather than the amount of computational processing power they possess.

If bitcoin's transition to renewable energy sources does not happen quickly, Hoskinson is among several experts who predict that investors and consumers will look to other cryptocurrencies that are less environmentally damaging.

BLOCKCHAIN, COVID-19, SATAN, AND YOU…

Metrics details. Blockchain technology is swiftly entering the fields of humanitarian and development aid. While it has the potential to revolutionize the aid sector, e. This essay outlines the use cases of Blockchain technology for the humanitarian and development sectors and reflects on potentials and pitfalls that come with the adaptation of this new technology. Blockchain technology is rapidly reshaping the digital tools we use to conduct daily transactions. As such, Blockchain has emerged as a disruptive technology, which has not only laid the foundations for cryptocurrencies, but also the field of smart contracts. Critiques raise issues such as data protection and power consumption, and advocates herald a new era of digital transactions.

Blockchain in supply chain management is expected to boom over the next five years. It is hash of the previous block in the chain, transaction records.

The Big Blockchain Lie

Blockchain is a technology that allows transactions to be secure and anonymous. In short, blockchain creates a true peer-to-peer secure transaction. Blockchain has two main jobs :. Take a look how Blockchain expands to these industries. Today crowdfunding has an accountability problem. So what happens if you give money to the wrong campaign and someone misuses the money? You may never want to support a tech project again. With blockchain technology, you know more information. On the other hand, creators will receive more support for their projects with lower fees and overall cost, without hefty fees from lawyers. You hold some money in escrow.

This study aims to better understand the role of centralized and decentralized ledgers in the money supply process. The aim is to highlight the strengths, weaknesses, opportunities, and threats of these tools in the context of finance and banking. A thorough investigation of the prior literature was carried out using sources extracted from various academic databases. A SWOT analysis based on an integrative literature review methodology was conducted to synthesize various research contributions and analyze relevant information related to centralized and decentralized ledgers.

Platforms and Blockchain Will Transform Logistics

By Keith Griffith For Dailymail. The IRS has warned that the cryptocurrency space and related non-fungible tokens are ripe for financial crime , alerting potential traders to exercise caution and be aware of the tax implications. Korner said that digital assets were a growing area of concern for regulators and tax collectors, and that the space was rife with money laundering, market manipulation and tax evasion. Non-fungible tokens, or NFTs, are a trendy new technology that involves a unique digital token encrypted with an artist's signature, which verifies its ownership and authenticity. NFTs can represent ownership of digital assets, including images, video, music, trading cards, cryptocurrency wallet names and even land within online virtual worlds.
