Our research and analysis identified more than 65 existing and emerging blockchain use-cases for the environment through desk-based research and interviews with a range of stakeholders at the forefront of applying blockchain across industry, big tech, entrepreneurs, research and government.
Blockchain use-case solutions that are particularly relevant across environmental applications tend to cluster around the following cross-cutting themes: enabling the transition to cleaner and more efficient decentralized systems; peerto-peer trading of resources or permits; supply-chain transparency and management; new financing models for environmental outcomes; and the realization of non-financial value and natural capital.
The report also identifies enormous potential to create blockchain-enabled “game changers” that have the ability to deliver transformative solutions to environmental challenges. These game changers have the potential to disrupt, or substantially optimize, the systems that are critical to addressing many environmental challenges.
The most advanced digital society in the world is a former Soviet Republic on the edge of the Baltic Sea.
And by handing over €50 [since this story was published, this price has increased to €100] and a photograph, allowing my fingerprints to be taken and waiting a few weeks while my credentials were verified, I have been issued with an identity card, a cryptographic key and a PIN code to access its national systems. I am now an official e-resident of the Republic of Estonia, as is the Japanese prime minister, and you will want to be one, too. And what's more, by doing so, you'll be part of a system that could not only reinvent public services for the internet age, but fundamentally redefine what it means to be a country.

The Philippines has a rapidly emerging economy with a population of over 100 million. However, two-thirds of the population remains unbanked. 70 million Filipinos have severely limited access to both the domestic and global financial ecosystems. This poses a significant problem when up to 10% of the Philippines’ GDP is made up of international remittances sent from overseas workers to family members across the country.
When one talks about technology that could potentially change the way we live, blockchain is a term that is constantly brought up. And for good reason, blockchain technology promises to fundamentally change the way we live in a multitude of areas. It can often be difficult to conceptualize the transformative impact that blockchain can have on our lives, which is why I have decided to compile a list of potential blockchain use cases. Hopefully this list will give you a clearer insight as to the potential of this piece of technology. Just to add, this list is by no means an exhaustive one.

Electronic Medical Records (EMRs) crave innovation. Years of regulation have stifled tech development in medical data management, while an array of incompatible back-end systems and fragmented data trails limit patients' ability to engage with their medical history. We demonstrate MedRec as a solution tuned to the needs of patients, the treatment community, and medical researchers.
How can blockchain technology help improve the supply chain? All physical products must take a journey from the factory to the consumer and this journey is called the supply chain. Unfortunately, the path to the consumer isn't straightforward, there are sometimes dozens of intermediaries involved in this process. That includes quality assurance, drivers, procurement officers, etc. Blockchain acts as an immutable store of data, and removes the need for one or more third parties. It can help save both businesses and consumers time and money in this case. In this video I'll demo a solidity app that tracks asset, talk about a real world example called SyncFab, and discuss the different ways blockchain can affect the supply chain. Enjoy!
Americans broke out their pocketbooks to give over $410 billion to charity in 2017, a 5.2% increase from the previous year. However, a series of scandals have rocked the way that the public perceives the typical charity, and trust in charitable organizations recently cratered to 57%, the lowest the figure has dipped since 2005. It’s no coincidence that headline-grabbing scandals in the world of philanthropy coincided with the decline in faith toward these organizations.

Presented at the Singularity University's Innovation Partnership Program (IPP), this is an entry level talk about bitcoin by Andreas Antonopoulos.
What functions of money does the current stage of bitcoin fulfill? What is the current popular use case? Why will unit of account be the last function we achieve? Which use cases will accelerate bitcoin adoption in western countries (ex. Germany)? Why should we not be so hard on speculation and hedging against devaluation? What is the appeal of sound money? Will bitcoin become a world reserve currency? Why is gold not a good medium of exchange? How do we incentivise spending of bitcoin, when the current trend is to hold? Why is HODLing simultaneously hard? Why do mainstream economists call it "hoarding" instead of "saving"?
The killer application for electronic networks isn't video-on-demand. It's going to hit you where it really matters - in your wallet. It's not only going to revolutionize the Net, it will change the global economy.
The central bank of the United States, the Federal Reserve, has put out “educational material” on Bitcoin for teachers and students (including a quiz!). The Bitcoin parts are odd enough, but this and a subsequent blog post will focus on the following statement: “traditionally, currency is produced by a nation's government.“ Is that a fair representation of monetary traditions? At the very least it is quite incomplete. This two-part series will proceed back in time, showing some of the many examples non-governmental money, in order to fill in some of the gaps.
