As far as I know, yes. When you initialise your hardware wallet, it generates a new private key with new associated addresses. While you could perhaps import your old MEW privkey into the wallet by using the seed phrase-based restore function of the HW, this would defeat the HW’s secure privkey generation… so it would be a bad idea.
The blockchain, originally called the block chain is a public journal that contains records or blocks that are all linked and encrypted by the use of cryptography. Data is kept securely, hence, no access by unauthorized personnel or hackers. Besides, it is protected from central failures and other unexpected occurrences.
Some miners pool resources, sharing their processing power over a network to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A “share” is awarded to members of the mining pool who present a valid partial proof-of-work.
Years of regulation have stifled tech development in medical data management, while an array of incompatible back-end systems and fragmented data trails limit patients’ ability to engage with their medical history. We have developed MedRec, an open-source program that applies blockchain smart contracts to create a decentralized content-management system for healthcare data, and have piloted the project with Beth Israel Deaconness Medical Center. MedRec sets up an authentication log to govern medical record access, while providing means for auditability and data sharing. Its modular design integrates with providers’ existing, local data storage solutions, enabling interoperability. The system engages directly with medical researchers, who provide the “mining” needed to secure and sustain the authentication log on a private, Ethereum network. Read the whitepaper here.
A DCI team, working with students and faculty from the MIT Sloan Management school and MIT Engineering Department, is exploring using digital currency and distributed-ledger technology to securitize transactions among users and owners of blockchain-managed solar microgrids. The goal is to create a secure form of reliable, executable collateral to lower risks for lenders and reduce the cost of financing decentralized renewable energy infrastructure, especially in developing countries. The team is developing an Ethereum-based smart contract that triggers timed access to a solar electricity resource while payments by the user are up to date. The idea is to create a form of “smart property” whose usage rights can be managed remotely. The team is exploring different investment structures to manage these resources, including a cooperatively owned microgrid in which power generation, sharing and usage, as well as payments and administrative protocols are governed via decentralized, blockchain-based mechanisms. Pilot sites are being explored in India and other parts of the developing world. The long-term objective is to create a platform upon which financial engineers can create structured securities backed by solar generation revenues, allowing higher level capital to flow down to local projects and finance the ongoing rollout of a decentralized renewable infrastructure in the developing world.
However, because cryptocurrencies are virtual and do not have a central repository, a digital cryptocurrency balance can be wiped out by a computer crash if a backup copy of the holdings does not exist. Since prices are based on supply and demand, the rate at which a cryptocurrency can be exchanged for another currency can fluctuate widely.

In what world has any technology only been used soley for good, legal, activities? Criminals use computers, cell phones, etc. The internet itself supports trillions of $ worth of illegal activities. If the ban/illegalize logic is based on use of XYZ by criminals, many things “should be illegal”… there’s not many ways to eliminate criminals from profiting from technology. Many countries have death penalty for dealing drugs, yet there are those willing to PROFIT and risk their life, it’s human nature.
But like when I ignore a bill, it doesn’t go away, by the time I deal with it, it usually costs me more, maybe a fine. I think you may have the same problem. Go and look at Circle, they just bought this exchange we use called Poloniex for $400m. I guarantee this is going to look cheap in a year or two. Like when Facebook bought Instagram for $1bn and then a few years later paid $19bn for Whatsapp.
Open-source and global, Litecoin, like Bitcoin, is also fully decentralized, with mathematics securing the network. Some people point to Litecoin’s faster transaction times as an improvement over Bitcoin.
Here we are again and I’ve seen this movie before. New platform, new ideas, but a LACK of applications… so far. Ripple’s application to me looks like a key piece marrying fiat currency with digital currencies. Function, available supply and mission. Of the more than 1,300 crypto currencies out there many have very limited function…I want broad function, everyday transactions. XRP could have that.
But there remains no bigger mania among tech investors than cryptocurrency, which some see as an eventual replacement for traditional, government-issued money. Even with the recent declines, the price of Bitcoin has more than tripled this year; another cryptocurrency, Ethereum, has gained more than 2,300 percent. The success of these currencies has minted a new class of “crypto-millionaires” and spawned hundreds of other digital currencies, called altcoins. In addition, it has given rise to an entire category of start-ups that take advantage of cryptocurrency’s public ledger system, known as the blockchain.
Bitfinex is a well established exchange that allows you to buy Ethereum if you live outside of the US. Another issue is that the exchange recently halted fiat deposits so you’ll need to have some sort of cryptocurrency if you want to buy Ethereum through this platform.
This is another open source cryptocurrency which introduces something new into the crypto world: instant transactions. Originally introduced to the cryptocurrency market as Darkcoin, this currency was renamed Dash on March 25th, 2015. Unlike other currencies, Dash uses X11 as a chain hashing algorithm for its proof-of-work system. It was one of the currencies which started with a set of pre-mined coins, estimated to be about 1.9 million coins which are equal to about a quarter of the current Dash coin supply. The developer of Dash faced his fair share of issues when working with Dash, one of which was known as an “instamine” error. After resolving the problem, the developer suggested a re-launch of the cryptocurrency but the community strongly insisted on leaving everything as it is and progressing with the development of the currency. At one point, Evan Duffield, the lead developer and creator of Dash, suggested that an airdrop of Dash was needed to broaden the initial distribution of the coin. This was also overwhelmingly rejected by the community. The Dash community is one of the most active around the cryptocurrency side of the internet, and the current capitalization of Dash is over $500 million USD.
Report rules violations. The rules are only as good as they are enforced. Mods cannot be everywhere at once so it is up to you to report rule violations when they happen. Do not fall victim to the Bystander Effect and think someone else will report it.
What you really have when you own a bitcoin is the collective agreement of every other computer on the bitcoin network that your bitcoin was legitimately created by a bitcoin “miner”, and then passed on to you through a series of legitimate transactions. If you want to actually own some bitcoin, there are exactly two options: either become a miner (which involves investing a lot of money in computers and electricity bills – probably more than the value of the bitcoin you’ll actually make, unless you’re very smart), or simply buy some bitcoin from someone else using conventional money, typically through a bitcoin exchange such as Coinbase or Bitfinex.
