Quoted: “Blockchains are thus an intriguing model for coordinating the full transactional load of any large-scale system, whether the whole of different forms of human activity (social systems) or any other system too like a brain. In a brain there are quadrillions of transactions that could perhaps be handled in the universal transactional system architecture of a blockchain, like with Blockchain Thinking models.”

Bitcoin mining is not a pretty business. It requires lots of specialized servers that are essentially unusable for normal computing and lots of cooling. But when you bring thousands of miners together in the same room, things really get ugly.
Motherboard has some fascinating footage of a bitcoin mine in Liaoning Province, China. The mine, set up in an unused factory, is a snakes’ nest of wires and high-powered fans, a sort of high-tech server farm that is so resource-intensive that it has to be optimized to a fault.

The recently concluded Bitcoin & the Blockchain Summit in San Francisco on January 27 came up as a vivid source of both anxiety and inspiration. As speakers tackled Bitcoin’s technological limits and possible drawbacks that can be caused by impending regulations, Bitcoin advocate Andreas Antonopoulos lifted up everyone’s hope by discussing how bitcoins will eventually survive and flourish. He managed to do so with no graphics or presentations to prove his claim, just his utmost confidence and conviction that it really will no matter what.
On the currency being weak
There have been statements about Bitcoin’s technology surviving, but not the currency itself. Antonopoulos, however, argues that Bitcoin’s technology, network, and currency are interdependent with each other, which means that one element won’t work without the other. He said: “A consensus network that bases its value on the currency does not work without the currency.”
On why Bitcoin works
Antonopoulos underscores the fact that Bitcoin works because it is a dumb, transaction-processing network. Calling Bitcoin dumb is far from disparaging Bitcoin’s image as he actually thinks of this dumbness as Bitcoin’s true source of strength. According to him, it is a dumb network that supports smart devices, pushing all of the intelligence to the edge. It’s an innovation without permission.
On being 2014’s worst investment
Antonopoulos also argues that those who believe bitcoins to be a bad investment only considers the price when there are other equally important factors to be looked upon such as continuous investments and technological innovations.
For instance, 500 startups were created in 2014, which generated $500 million worth of investments and produced thousands of jobs, some portion from Bitcoin gambling. This was also the year that two remarkably genuine technologies were created, the multi-sig and hierarchal deterministic (HD) wallets.
On waiting for Bitcoin to flourish in 2017
Antonopoulos then stated with unwavering certainty: “Give us two years. Now what happens when you throw 500 companies and 10,000 developers at the problem? Give (it) two years and you will see some pretty amazing things in bitcoin.”
On mining updates
Meanwhile, mining for bitcoins prove to be more challenging than before. A Bitcoin mining facility in China, for instance, generates 4,050 bitcoins every month, which is equivalent to around $1.5 million, but not without repercussions and complexities. The entrepreneurs in the mining facility realize that as the level of difficulty and computing power increase, the ratio also gradually changes.
Typically, the entire mining procedure utilizes about 1,250 kilowatt-hours of electricity, putting the factory’s electricity bill to about $80,000 every month. Nowadays, their miners produce 20–25 bitcoins a day, significantly lesser compared with their previously 100 mined bitcoins per day.
On leaving a thought
The confidence for Bitcoin’s bright future has been regained, thanks to Antonopoulos’ contagious exhilaration and resolute belief in its potential. However, we can only wonder what the increasing difficulties in mining for bitcoins entail to the cryptocurrency’s overall performance and future, though Bitcoin’s unique features have been proven to be strong and resilient enough to surpass any challenges.

Cameron and Tyler Winklevoss aren’t shy about issuing bold predictions for Gemini, their recently revealed bitcoin exchange project.
Calling it the “NASDAQ or Google of bitcoin”, the president and CEO, respectively, believe Gemini will be the fully regulated, fully compliant and fully banked institution the US bitcoin ecosystem needs to develop to its full potential.
In a new interview with CoinDesk, the brothers – prominent bitcoin investors and two of the largest-known holders of bitcoin – opened up about Gemini, discussing why they feel the exchange can become the market leader in what has been an increasingly active part of the bitcoin space.

Bitcoin’s ideological foe is becoming its saving grace.
To many Bitcoin enthusiasts, the decentralized currency’s allure was that it was designed to exist beyond the reach of government regulation. Free from central banks, its value wasn’t tied to government policies or geopolitical factors.
But now it seems the very regulation its creator or creators (since we don’t actually know who first minted Bitcoin) guarded against is what’s now buoying the cryptocurrency’s price. Read more
Bitcoin as a cryptocurrency has had its moments of strength and weakness. The technology behind bitcoins, however, is a different story. While skeptics don’t expect a lot from Bitcoin as an alternative currency because of its volatility, they do have high hopes for the technological innovation that powers it, believing that it can be further developed to create something much powerful than Bitcoin itself.
To those who know Bitcoin as a great way of transacting online, but don’t completely understand its dynamics, it’s time to get acquainted with the cryptocurrency’s mathematical wonders that make anonymous, faster, and cheaper transactions of moving funds on the internet possible.
Most of us know that Bitcoin uses the SHA-256 hashing algorithm, but hashing serves a different function and purpose from that of digital signatures. Hashing actually provides proof that a message has not been changed because running the same hash always generates similar result.
Any message, regardless of the size can go into a hash function where the algorithm breaks it down, combines the parts, and “digests” it until it makes a fixed-length outcome called “digest”. However, a good hashing algorithm possesses some critical characteristics, in which the same message always produces the same result, as mentioned above, and it only works in one direction.
This means that even the smallest change creates a completely different digest. This is called the “avalanche effect”. Also, the chances of generating the same digest from a transformed message are a tad rare. This is called “collision resistance”.
Such nature of Bitcoin’s hash function makes it impossible to change records and transactions once they have been documented. As soon as the hashes are hashed together within the blockchain, counterfeiting records of transactions is no way near possible.
Then there’s the technology of wallet software. This is where people store bitcoins and use for making transactions. The wallet system is set in which users are prohibited from spending the same units twice (double-spending) by checking new transactions against the blockchain and against other new transactions to ensure the same units are not being cited more than once.
Though this system was established to avoid fraudulent activities and has proven to be an effective one, it also became an ideal scenario for hacking attacks on a Bitcoin exchange that aim to steal bitcoins. It’s because once bitcoins are lost, they’re gone for good and there’s no way of reclaiming them, especially that cryptocurrency usage is not covered by the central government and other intermediary parties like banks. Nonetheless, it’s not totally the Bitcoin’s fault; it’s the Bitcoin exchanges’ security measures.

It is January 2014 and at least 400 people are packed into a conference hall in Miami Beach. High-profile journalists stand against the walls. Powerful venture capitalists crouch in the aisles. Banking and finance gurus crane their necks from the back of the room. They’re waiting for one of the most anticipated presentations of the 2014 North American Bitcoin Conference. A massive surge in interest from the media has just pushed the price of a single Bitcoin to around $900, up nearly 800 per cent in three months. Bitcoin Miami is the largest ever conference of its kind. In this moment, the possibilities for Bitcoin seem limitless.
What appears to be a teenage boy mounts the stage. The crowd goes quiet. In fact, Vitalik Buterin – all acne-splotched face, spidery fingers and shining eyes – is just a few days shy of 20. He surveys the audience nervously for a moment, then kicks off his presentation by lauding the benefits of the Bitcoin payment network – its speed, security, economy and autonomy.
Bitcoin exchange Coinbase has brought innovation to the next level by opening the first ever licensed US Bitcoin exchange. Backed by $106 million from the New York Stock Exchange, banks, and venture-capital firms, Coinbase’s newly launched US exchange, said to be named Lunar, will provide greater security features; so as not to repeat the mistakes of Mt. Gox and Bitstamp, the former of which declared bankruptcy last year while the latter has sustained hacking attacks and is now back in the game.
Coinbase has already acquired licenses from 50% of the states in the country, which includes New York. The remaining 50% is still in the works and is necessary to complete to be able to provide full nationwide services. Also, Coinbase does not only look at expanding nationwide, it also looks at expanding worldwide in offering their Bitcoin-related services.
Of this plan, Coinbase CEO Brian Armstrong said: “Our goal is to become the world’s largest exchange”.
For this vision to be realized, Coinbase must make sure that no security attacks will ever threaten the safety of every user’s bitcoins, which is something that the company seeks and proves to show.
On the other hand, Coinbase is not the only one that has the same vision. Entrepreneurs Tyler and Cameron Winklevoss, widely known for their work on Facebook, are also eyeing on the same project.
The twins have already taken the necessary steps such as hiring engineers, enlisting a bank, and engaging with regulators to begin the process of opening their own Bitcoin exchange in the next months to come. The exchange will be named Gemini, Latin for twins.
Despite the volatile prices and security attacks on other exchanges, the Winklevoss twins haven’t lost their confidence in bitcoins and the technology that powers it, which is why they consider a reliable and regulated exchange extremely necessary to bring bitcoins up on its feet again.

Quoted: “Looking at the misinformation, speculation, and confusion about bitcoin and blockchain technology: it’s the same conversation we had 20 years ago with the Internet. In the early 90s, the only way you could check your email was through a command line prompt. Then, web browsers were developed, small websites were created, and…well, as you can see, a lot has changed since. It’s looking as though bitcoin is just the first app to use blockchain technology, just like email was the first app to use the Internet.”
