Blockchain mining cannot catch a break when it comes to environmental sustainability. This is especially true for Bitcoin mining which seemingly has an insatiable appetite for electricity. A recent paper suggests that by 2020 Bitcoin mining will consume as much energy as Australia. While these estimates are not exempt from criticism, mining does not appear to be best friends with sustainable development, at least not for now. An alternative way to look at this issue is to compare Bitcoin’s mining power use to that of cloud-based providers who have now become well-established tech corporations. Such comparison should be made not only in absolute terms (gigawatts) but also in relative fashion by considering, for example, the total population being served by these platforms and networks.
Many observers seem to assume blockchain technology is an immovable monolith. While such assumption does help when trying to explain how the technology works to the general public, this is indeed not the case when it comes to describing the actual status of the technology.
Rapid and agile innovation is one of the core traits of blockchains, backed by impressive human talent with substantial financial resources, addressing not only some of its well-known limitations but also enhancing its core functionality. Blockchain technology is evolving rapidly and the best way to take stock, for now, it’s via frequent snapshots. In fact, keeping track of blockchain innovations could quickly become a full-time job. In any event, the monolith is not only moving. It is indeed flying at the speed of light.
Open source is one of the core traits of blockchain technology propelling its rapid adoption and growth. The source code from the most popular platforms such as Bitcoin, Ethereum, and Hyperledger Fabric is freely available for download by anyone who wants to play with the technology. Granted, users wishing to deploy and use these platforms must have the required technical skills. While average Internet users might not have such capabilities, companies and startups can find internal capacity or hie external expertise to run and manage their preferred blockchain platform.
Free and Open Source Software (FOSS) has been around for almost three decades. Back in the late 1990s, a war of sorts between FOSS and proprietary software commenced, attracting lots of media attention and generating plenty
ICO data for last February is now available and shown in Figure 1 below.
We can immediately see that both the number of ICOs and the total investment volume has decreased. The latter, which amounted to 1.2 billion USD for the month, is 20 percent less than the total for January this year. The same goes for completed ICOs which decreased 21 percent. Among them, only one ICO surpassed 100 million dollars, reaching 150 million. And it managed to distance itself from the runner-up by a cool 100 million.
Figure 2 confirms the decline in total monthly investment but shows that the median declined only slightly or about 1.2%.
Even so, the median investment per ICO is still above 16 million dollars.((The average is much higher but probably not significant as the statistical distribution
I was invited to Canada to discuss my blockchain technology paper. Here are my opening remarks at the panel organized by Government Affairs and IDRC.
Speaking about a seemingly complex subject such as blockchains poses a challenge not only for me but also for you, the audience. More so when the time is scarce. It is probably not the same challenge, however. So perhaps the best way to start this conversation is to take a step back and start with technological innovation. Technological innovation has been around longer than you and me, for sure. But what has changed nowadays is the frequency in which innovation is happening, especially since the dawn of digital computing and electronics.
The Internet is no doubt the best example here. Initially conceived with government support and public
Recent events seem to suggest the cryptocurrency bubble is finally starting to deflate. Bitcoin, Ethereum and most of their crypto cousins are significantly down while regulators in several countries are finally beginning to take action on the ground. Nobel laureate economists are also speaking up against the digital currency, arguing that the new currency is not capable of fulfilling the three core functions that define money.
Does this mean that ICOs are on the way out?
If we look at the latest ICO data,((Data was obtained from tokendata.io. Sample size includes 1032 ICOs completed by the end of 31 January 2018. 485 or 47% percent did not report any funding. The total number of successful ICOs is thus 547. The DAO ICO is not included as it is considered a failure. Hdac, quoted by some
Like previous digital technologies, such as the Internet, for example, blockchain technology (BCT) has been driven by a high degree of techno-optimism not yet backed by on the ground impact or reliable evidence. Undoubtedly, the technology, which is still in its infancy, has enormous potential in many sectors and could promote human development if harnessed strategically.
One of the many BCT innovative traits is the use of sophisticated cryptographic tools to generate unique identities for individuals interacting within its distributed network. In general, such identities are pseudo-anonymous, immutable, secure and directly created and managed by the individual. This in principle makes BCT an ideal candidate to propel further innovation in the digital identity sector. The critical question
While not the only cryptocurrency around, Bitcoin was the first to solve the well-known double-spending problem that characterizes digital currencies. Tackling the issue demanded the creation of blockchain technology (BCT) combined with the use of a brute force algorithm known as proof of work.
Created in 2009, Bitcoin is now one of the largest (and most unstable) currency in the world (Says & Says, 2017). Launched in the fringes of the Internet and initially used only by computer geeks, the cryptocurrency has now become a hot financial asset attracting both traditional and new investors. Word out there is that Bitcoin billionaires do not spend because they fear losing money as Bitcoin rapidly appreciates over time and ad infinitum (Tucker, 2017).
Bitcoin and its crypto-cousins have
After remittances and land titles, refugees are perhaps one of the primary targets of blockchain technology (BCT) initiatives promoting development or social impact. Bitnation, Aid:Tech and the UN World Food Programme, among many others, are good examples. Last month, at a BCT meeting in New York, UN Women shared its plans to launch a blockchain lab in early 2017. And women refugees are a top priority in the lab’s agenda.
No doubt refugees have become a critical issue of global scope, especially after the forced displacement of hundreds of thousands of Syrians in the last few years. Syrians escaping civil war had no choice but to leave their homes, belongings, and country seeking more peaceful and secure lands. What is different today is the scale of this forced migration which seems unprecedented
Identity access and management (IAM) is perhaps one of the areas where Blockchain Technology (BCT) could make a real difference. Research I am currently undertaken indicates that over one hundred BCT startups around the globe are focusing on this area. Add to this number the many other startups and organizations who have been engaged with digital identity for many years now but do not use BCT.
Also, factor in target 16.9 of the UN Sustainable Development Goals (SDGs) that explicitly calls for universal legal identity provision, including birth registration for all children around the globe. The ID2020 global public-private partnership is now spearheading these efforts.
