How Long Would It Take to Mine Bitcoin by Hand?

Posted by in category: bitcoin

Written By: — Singularity Hub

Bitcoin is a decentralized, digital currency. It was invented by a mysterious individual known by the handle, Satoshi Nakamoto. A bitcoin is volatile but is currently worth about $380; regulators are increasingly interested; retailers too—true believers believe.

These headlines you’ve likely read. But where the hell do bitcoins come from anyway? They’re mined by computers making calculations lightning fast—or in this case, by a man with sixteen minutes’ free time, a pencil, and pad of paper.

BitCoin, Cryptocurrency, and Blockchain Technology — The Ethereum Primer

Quoted: “Ethereum will also be a decentralised exchange system, but with one big distinction. While Bitcoin allows transactions, Ethereum aims to offer a system by which arbitrary messages can be passed to the blockchain. More to the point, these messages can contain code, written in a Turing-complete scripting language native to Ethereum. In simple terms, Ethereum claims to allow users to write entire programs and have the blockchain execute them on the creator’s behalf. Crucially, Turing-completeness means that in theory any program that could be made to run on a computer should run in Ethereum.” And, quoted: “As a more concrete use-case, Ethereum could be utilised to create smart contracts, pieces of code that once deployed become autonomous agents in their own right, executing pre-programmed instructions. An example could be escrow services, which automatically release funds to a seller once a buyer verifies that they have received the agreed products.”

Bitcoin, Cryptocurrency, and Blockchain Technology — Voting Systems

Posted by in categories: automation, big data, bitcoin, business, complex systems, computing, disruptive technology, economics, encryption, engineering, ethics, geopolitics, government, hacking, hardware, information science, innovation, law, materials, open access, open source, philosophy, policy, polls, privacy, science, security, software, supercomputing, transparency, treaties

Quoted: “Bitcoin technology offers a fundamentally different approach to vote collection with its decentralized and automated secure protocol. It solves the problems of both paper ballot and electronic voting machines, enabling a cost effective, efficient, open system that is easily audited by both individual voters and the entire community. Bitcoin technology can enable a system where every voter can verify that their vote was counted, see votes for different candidates/issues cast in real time, and be sure that there is no fraud or manipulation by election workers.”

BitCoin, Cryptocurrency, and Blockchain Technology — FACTOM

Posted by in categories: automation, big data, biotech/medical, bitcoin, business, complex systems, computing, disruptive technology, economics, education, encryption, engineering, environmental, ethics, finance, futurism, geopolitics, hacking, information science, law, materials, open access, policy, science, security, software, supercomputing, transparency

Quoted: “The Factom team suggested that its proposal could be leveraged to execute some of the crypto 2.0 functionalities that are beginning to take shape on the market today. These include creating trustless audit chains, property title chains, record keeping for sensitive personal, medical and corporate materials, and public accountability mechanisms.

During the AMA, the Factom president was asked how the technology could be leveraged to shape the average person’s daily life.”

Kirby responded:

“Factom creates permanent records that can’t be changed later. In a Factom world, there’s no more robo-signing scandals. In a Factom world, there are no more missing voting records. In a Factom world, you know where every dollar of government money was spent. Basically, the whole world is made up of record keeping and, as a consumer, you’re at the mercy of the fragmented systems that run these records.”

A New Economic Layer — BitCoin, Cryptorcurrency, and Blockchain Technology

Preamble: Bitcoin 1.0 is currency — the deployment of cryptocurrencies in applications related to cash such as currency transfer, remittance, and digital payment systems. Bitcoin 2.0 is contracts — the whole slate of economic, market, and financial applications using the blockchain that are more extensive than simple cash transactions like stocks, bonds, futures, loans, mortgages, titles, smart property, and smart contracts

Bitcoin 3.0 is blockchain applications beyond currency, finance, and markets, particularly in the areas of government, health, science, literacy, culture, and art.

BitCoin, Cryptocurrency, and Blockchain Technology — A Brief Q&A

Posted by in categories: bitcoin, disruptive technology, economics, finance, geopolitics, government, information science, innovation, law, open source, transparency

My Brief Q&A session with Christoffer De Geer, about BitCoin, Cryptocurrency, and Blockchain Technology.

This Q&A was first published by Mr. Geir Solem, Director of Cryptor Trust Inc., on the Cryptor Primary Investor Blog (Date: October 31, 2014).

Quote: “BitCoin was the first small step in what I believe will be a truly transformational journey, for each and every one of us. In 10 Years Cryptocurrency and Blockchains have every chance to have the same, or greater, impact on our lives, society, and civiliation, as the creation of Email had to the Postal Service, and the Fax Machine as compared to the Internet; in 25 Years Monetary Systems, Systems of Trade and Exchange, Systems of Transaction of Goods, Ledger and Recordation Systems, Everything You Know – Will – Be – Different – and, Unrecognizable relative to what we know today at the end of the year 2014.”

Bitcoin gains support of cryptography think tank

Posted by in category: bitcoin

by - c/net

Bitcoin, the best known form of virtual currency, faces numerous obstacles to widespread acceptance and adoption, but a new group called Coin Center has added a voice of support.

The organization is led by Jerry Brito, a law professor and a former research fellow at George Mason’s Mercatus Center. In an announcement made Thursday, Brito said Coin Center is a “new non-profit research and advocacy center focused on the public policy issues facing cryptocurrency technologies.” Bitcoin was the first and still the best known virtual currency or crytocurrency, which means that cryptography is used for its transactions and its creation.

Hayley Tsukayama — WashingtonPost

United Way Worldwide announced Monday that it will begin taking donations in Bitcoin, the digital currency.

Bitcoin users can now use the currency for donations to the United Way’s Innovation Fund, a part of the United Way dedicated to updating the organization through “technology, relationships and efficiency.” Coinbase, one of the leading Bitcoin payment platforms, is partnering with the charity to let those interested donate directly from their digital Bitcoin wallets to the fund. According to a page on the United Way’s Web site, anyone from around the world can donate to the fund using Bitcoin.

Celebgate Could Inspire More Bitcoin Blackmail

bitcoin hacker blackmail

The Celebgate incident is still unfolding, and we are already seeing mainstream media report on the connection between the “nude celebrity photos” and Bitcoin. The original leaker of the pictures returned to 4chan recently to respond to the uproar he had caused. An excerpt from his post highlights Bitcoin’s involvement in Celebgate:

People wanted **** for free. Sure, I got $120 with my bitcoin address, but when you consider how much time was put into acquiring this stuff (i’m not the hacker, just a collector), and the money (i paid a lot via Bitcoin as well to get certain sets when this stuff was being privately traded Friday/Saturday) I really didn’t get close to what I was hoping.
