5 Global Problems Bitcoin's Proof of Work Can Help Solve
It is possible that when compared to rare metals, bitcoin mining is not as wasteful in terms of environmental impact, but it remains clear that there could be better and more efficient uses of cryptocurrency mining power than solving arbitrary cryptographic problems. This belief can be seen in a number of innovative projects announced in recent weeks that seek to use bitcoin's mining power to do everything from storing genetic material to archiving important data. This increasingly important question about the future of one of bitcoin's core industries arrives at a time industrial mining....

I've long been interested in ways to use cryptocurrency mining to solve practical problems; proof-of-work's waste of energy is its biggest problem, the solution to which could be the final nail in fiat's coffin. While Gridcoin showed some promise, it failed to take off, and the search for a scientific coin capable of taking us to the moon continues. Many seemed to criticize its centralized nature--a central authority vets which scientific programs users can participate in, and validates their efforts--and maintaining proper security while dedicating more resources to useful work has proven....
A lot has been made of Bitcoin's environmental impact. With the mining network now more powerful than all of the world's top supercomputers combined, it's understandable that some people would become concerned about power consumption and waste. Shouldn't there be a better way to do this, and is it even worth it, at all? First, to answer the former question. One alternative to using processing power to mint coins-known as proof-of-work-is the proof-of-stake system. In proof-of-stake, new coins are minted (and the network secured) by those holding coins in the same place for a period of....
Algorand's PPoS consensus algorithm distinguishes it from other blockchain networks that help solve blockchain trilemma. What is Algorand?Algorand is a blockchain network created in 2017 by Silvio Micali, an MIT professor who won the Turing Award for his work in cryptography. Algorand is a decentralized permissionless blockchain protocol that anyone can use to develop applications and transfer value. The Algorand protocol is powered by a novel consensus algorithm that enables fast, secure and scalable transactions.Algorand addresses the common issues that most older blockchains have,....
Several models for the development of nations for the next three to five years were presented by the World Economic Forum, where cooperation was emphasized as the foundation for successful and speedy economic and social recovery. Speaking at the WEF, Børge Brende, a Norwegian politician and member of the Conservative Party, said that “the direction in which we need to head is towards greater dialogue, coordination and collective action”. Even today in the world of global business, we’re seeing hundreds of examples of cooperation gone right, such as the UN Global Compact,....
Jaan Tallinn, the co-founder of Skype, is working on finding ways to use blockchain technology to solve problems that require global cooperation, such as overfishing, crime, corruption and deforestation, according to The Telegraph. Jaan Tallinn was speaking at the International Business Festival, a global marketplace for making connections, in Liverpool, U.K. The festival runs through July 1. After helping people save long distance relationships with a video phone platform, the Estonian entrepreneur has committed himself to “effective altruism,” data and reason guided compassion, using....
