The bitcoin book boom

by

For all the media coverage, and for all the venture capitalist interest, the average person on the street still knows nothing about bitcoin.

According to a study released by the nonprofit Coin Center last month, 65% of the general public is “not at all familiar” with the digital currency or its underlying technology. Of those who do have some awareness, 84% have never used it.

That hasn’t stopped authors from rushing in to churn out books on bitcoin. In 2014, hundreds of books were published on the topic. Why are business writers so intrigued? Fortune spoke to the authors of three recent serious books on the topic. Below are five questions from each conversation.

Popular torrent client can steal your CPU cycles to mine bitcoins

— Engadget

If you recently installed or updated uTorrent on your PC, you may have have picked up an unwanted passenger: a bitcoin miner called Epic Scale. If you don’t pay attention, that piece of code can be inadvertently installed with the latest uTorrent build (version 3.4.2). It can then use your computer as part of a bitcoin farm (Litecoin, to be exact) to generate revenue for third parties. Users first reported the situation on uTorrent’s forums, and it was quickly confirmed by a senior support manager. He said that the app “cannot be installed without permission,” but one user claimed that there was “never a warning about it,” even though he opted out of other bundled software.

Could Abra be Bitcoin’s “Killer App”?

Quoted: “At the event, CEO Bill Barhydt said: “Our mission with Abra is to turn every smartphone into a teller that processes withdrawals. This is not just another bitcoin app. The wallet is a full-fledged digital asset management system, and you don’t have to understand it.”

Use of the application is straightforward and relies on a network of people around the world who act as tellers, charging small fees to help people transfer money abroad. A user can deposit funds into his or her account using a debit card or by meeting up with a teller in person and handing them cash. Then those funds can be instantly — the power of Bitcoin — transferred anywhere in the world. The person receiving the money has only to find a teller, show that he or she is the recipient of the funds, and exchange the digital cash (denominated in USD) back for their local currency.”

Blockchains as a Granular Universal Transaction System

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.”

A Rare Look Inside A Massive Bitcoin Mine

by John Biggs — TechCrunch

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.

Bitcoin’s Unique Features Lighten Up its Ambiguous Future


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.

Gemini
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 libertarians now desperately need the government’s help

Quartz

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

The Mathematical Wonders behind Bitcoin


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.
