Bitcoin has prompted many people to expect a revolution in the means by which we make and settle everyday payments. Our view is that Bitcoin and other "virtual currency schemes" (VCS) lack critical features of money, so their use is likely to remain very limited.
As an early adopter of the internet (I got AOL in 1993), I have watched with fascination as Bitcoin has become more and more popular: with the media, ...
Since its introduction in 2008, Bitcoin, the world's most recognized and frequently used crypto-currency has continued to grow in popularity. Bitcoin's peer-to-peer decentralized structure has steadily attracted global users seeking to make purchases and transfers of money digitally, privately, and with minimal transaction costs.
BitNation is using the blockchain to help refugees in Europe. The organization's new series of Refugee Emergency Response services allow refugees to create a digital identity, which can be used to cryptographically prove their existence and who their families are.
A blockchain is public ledger of transactions that is distributed among all participants in a market or system. Each transaction that happens within a market or system must be verified by a strong majority of participants. It's very difficult to falsify transactions in a blockchain because each transaction generates a strong cryptographic signature.
If your kid downloads Tor or knows other kids who are on it, it's important to talk about the implications. The Deep Web isn't a safe place to hang out.
The blockchain is a key part of the system that underlies recordkeeping and transactions for Bitcoin, the virtual currency. But there are much bigger opportunities ahead for this decentralized recordkeeping system.

Activists can improve their alternative media success by embracing alternative currencies like Bitcoin. I live in Britain where I've just witnessed an entire generation of activists get their clock's cleaned by a Conservative sweep in the May 7th Parliamentary elections.
Just as a true artist lives by his or her art--creating and being remembered through a legacy of masterpieces--Nakamoto's anonymity perfectly mirrors the anonymity of his Bitcoin masterpiece.
The Comcast-Time Warner Cable deal may have been killed because regulators didn't believe that the resultant mega-ISP could be trusted as a central authority, but we are just a few years away from the emergence of a trustless society where digital citizens, like you and me, would have taken away that danger.
At the core of the next generation of the Internet is the technology underlying the digital currency Bitcoin: the blockchain. At its most basic, the blockchain is a global spreadsheet, an incorruptible digital ledger of financial transactions that can be programmed to record virtually everything of value and importance to humankind.
The notion of national currencies and fiat money is central to modern economies and government financing. I can't see a world in the foreseeable future, where sovereign nation states give up the control over what currency must be used for conducting its business.
