Understanding Decentralization and Blockchain Technologies. Bitcoin: How its core technology will change the world - tech - 05 February 2014. At the coalface: mining for money (Image: Stephen Lam/Reuters) The virtual currency is about more than money – the real innovation is what people are doing with the technology it is based on BITCOIN has been called many things, from the future of money to a drug dealer's dream and everything else in between.

Bitcoin: How its core technology will change the world - tech - 05 February 2014

But beyond creating the web's first native currency, the true innovation of Bitcoin's mysterious designer, Satoshi Nakamoto, is its underlying technology, the "block chain". That fundamental concept is being used to transform Bitcoin – and could even replace it altogether. So what is the block chain? Miners, people who run the peer-to-peer Bitcoin software, randomly generate hashes, competing to produce one with a value below a certain target difficulty and thus complete a new block and receive a reward, currently 25 bitcoins.

One of those tapping into its power is Vitalik Buterin, a 19-year-old developer from Toronto, Canada. Buterin says Ethereum is much more flexible. Bitcoin and the Three Laws of Robotics. By Stan Larimer, President, Invictus Innovations, Inc.

Bitcoin and the Three Laws of Robotics

You may not have considered it, but Bitcoin can be viewed as an unmanned company – or a Distributed Autonomous Corporation (DAC) if you prefer. Unlike passive currencies, Bitcoin derives much of its tangible value by performing a trustworthy confidential fiduciary service. Essentially, it keeps private books for customer “checking” accounts and will transfer credits between accounts upon receipt of a properly signed “check”. Aren’t these some of the same private services for which Swiss banks were once famous – back when privacy was something they could really offer? Isn’t Bitcoin more like a bygone Swiss Bank than a commodity or a colorful piece of paper? Would a DAC metaphor fit Bitcoin even better than its current coin metaphor?

Distributed Autonomous Corporations (DAC) run without any human involvement under the control of an incorruptible set of business rules. Asimov’s Three Laws of Robotics Steely-Eyed Geek(Homo Technosapien) The Proof-of-Work Concept. The Search Perhaps the least intuitive aspect of the Bitcoin network is the proof-of-work concept it uses to define the requirement for the generation of a new set of transactions (“block“) to be added to the distributed transaction database (“block chain“).

The Proof-of-Work Concept

This concept, which grew out of ideas from the early cypherpunk movement, is new to monetary theory and feels a little out of place in computer science too. I will show that biology gives us the most suitable framework for understanding it. Wall Street Analysts: Bitcoin Could Revolutionise the Non-Financial World Too. Bitcoin technology has the potential to revolutionise the way we buy and sell property, enforce legal documents and even place bets, according to a new report from financial services and investment firm Wedbush Securities.

The system of decentralized trust, meaning that there is no central authority, that underpins bitcoin could have applications beyond the payments world that is most commonly associated with the cryptocurrency, write the report’s authors Gil Luria and Aaron Turner. The report reads: “We see the potential for bitcoin technology to digitize and decentralize trust. The implications of eliminating the need for centralized trust may go beyond payment networks to areas such as securities markets, sports gambling and even legal contracts.” Decentralized Trust At its core, bitcoin is merely a way of recording transactions without the need for a central authority to confirm or verify those transactions.

Therefore it is decentralized. Goodbye Lawyers Regulation and investment in 2014. Block-chains and Bitcoin. Alex Payne quotes Chris Dixon: The press tends to portray Bitcoin as either a speculative bubble or a scheme for supporting criminal activity.

Block-chains and Bitcoin

In Silicon Valley, by contrast, Bitcoin is generally viewed as a profound technological breakthrough. and says: Now working at vogue venture capital firm Andreessen Horowitz, Dixon is in a fine position to speak for Silicon Valley. But to the extent that the Valley is a placeholder for the technology industry at large, I beg to differ. On the merits of Bitcoin as a currency or as an asset, technologists are split between optimists, who believe it (or a derivative of it) will be the default currency of the future, and skeptics (such as Payne), who see it as a flawed experiment with troubling political implications.

I don’t wish to comment on that debate, but I believe that, regardless of its usefulness as a financial asset, Bitcoin is a significant technological breakthrough. This is why I think alternative crypto-currencies are so interesting. Momentum accounting and triple-entry bookkeeping.
