Could Bitcoin be Dethroned by an Altcoin?

Posted by in categories: bitcoin, cryptocurrencies, disruptive technology, economics, encryption

Cryptocurrency aficionados have been discussing Bitcoin limitations ever since the blockchain buzz hit the street. Geeks toss around ideas for clearing transactions faster, resisting potential attacks, rewarding miners after the last coin is mined, and supporting anonymity (or the opposite—if you lean toward the altcoinsdark side). There are many areas in which Bitcoin could be improved, or made more conducive to one camp or another.

Distinguished Penn State professor, John Carroll, believes that Bitcoin may eventually be marginalized due to its early arrival. He believes that its limitations will eventually be overcome by newer “altcoins”, presumably with improved mechanisms.

So, does progress in any of these areas threaten the reigning champ? It’s unlikely…

Andreas-transparentMore than any other individual, Andreas Antonopoulos is the face of Bitcoin. We discussed this very issue in the outer lobby of the MIT Bitcoin Expo at which he was keynote speaker (March 2015). Then, we discussed it again, when I hosted his presentation at The Bitcoin Event in New York (also in March). He clearly and succinctly explained to me why it is unlikely that an altcoin will replace Bitcoin as the dominant—and eventually surviving—cryptocurrency

Blueprint for a Better Human Body — Rose Eveleth | The Atlantic

“But at the same time, there are more and more amputees who are going without the cosmetic covers, who are showing the machinery behind the leg, the hinges and the carbon fiber and the metal. And while function is still crucially important, there are people who are no longer asking how to replicate. Instead, they’re asking how to improve. How to make a limb new, better, stronger, more striking, more beautiful.”

Virtual reality: The emotion amplifier

“Probably the worst scenario as a game designer is that players experience something in your VR game that freaks them out so badly, they rip the headset off and refuse to put it back on again. Moreover, because VR is an emotion amplifier, all sorts of negative emotions and fears can become apparent that even the player may not have known about before. “ Read more

DRONES: How Drones Could Help an Indigenous Community Fight Mining and Deforestation Emiko Jozuka | Motherboard

Posted by in category: drones

“The local Wapichana monitoring team learned how to build a fix-winged drone from scratch. The team then mounted a GoPro onto the drone, which shot around 500 images of the Shulinab village along a pre-programmed flight path. Using Pix4Dmapper automatic imaging software, the team were then able to recreate a 3D model of their village from the images. The aim, explained MacLennan in a blog post, is to ‘create high-resolution up-to-date imagery at a fraction of the cost of satellite imagery.’” Read more

Neuroscientists Are Making an Artificial Brain for Everyone — Davey Alba | WIRED

“Nara is essentially a matchmaking system that finds and understands entities in any data set, from people and places to businesses and abstract concepts, then builds a massive knowledge graph that shows weighted links between those entities. Wilson says Nara inserts users right into that knowledge graph to offer personalized recommendations. Knowing a bit about the user is what allows Nara to light up other things they might like. And the system can scrape public databases to enhance its knowledge.”

“If the humans were controlling Atlas directly from the command center, this would be no big deal, but the MIT team designed for autonomy. So they don’t have a joystick that would make the robot open the door. All the team can do is send their robot the command to find the handle and open it. It’s up to the robot’s software to figure out how.” Read more

What Is the Metaverse? Philip Rosedale’s Big Dream for Immersive Virtual Worlds — By Jason Dorrier SingualrityHub

What is the metaverse? It’s Philip Rosedale’s second crack at playing god—at least in the virtual sense. Rosedale created his first virtual world, Second Life, in 2002. Now, he and his new company, High Fidelity, are building another world in silica—and this time, they’re thinking on planetary scales.

Speaking at the Silicon Valley Virtual Reality (SVVR) conference this week, Rosedale said that by harnessing the shared power of home PCs, “We could collectively create a space whose literal scale is comparable to the landmass of the planet Earth.” Sound ambitious? It is, and it isn’t. Read more
