If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Another way to prevent getting this page in the future is to use Privacy Pass. Bitcoin Cash was created back in August of last year. Many in the cryptocurrency community consider forks like these to be simple cash grabs at best, and potential scams at worst.
LCC as far as I can tell. Read on for a basic guide on how to safely sell your LCC. 0 of the popular miner was released about a week ago, and I’ve been running it on my own rigs for several days now with no issues. You can get the latest version here.

Note that you may have to whitelist it with your anti-virus software, as many flag Claymore as potential malware. If you rebooted your linux-based mining rig at some point in the last couple days, you may have noticed that your mining hashrate was drastically lower after your system restarted. Spectre vulnerabilities present in Intel CPUs was deployed on January 9th, and it had the unintended consequence of negatively impacting GPU mining speed. Thankfully, you can manually remove the update for now. Just follow these instructions and you should be back to normal. Thanks to the many readers that wrote in and made me aware of the issue! I intended to get this post up earlier, but I’ve been under the weather lately.
Now that we’re about a week into 2018, it’s probably a good time to talk about what’s in store for cryptocurrency as this decade winds down. I just don’t know what’s going to happen tomorrow. Just wanted to take a minute and wish everyone a happy holiday season! I’ve heard from quite a few of you over the past couple months, including some folks that started following my blog back in 2013. A few of you have indicated that you’re now crypto-millionaires, which is incredible. While I haven’t been able to respond to everyone individually, it’s been really amazing hearing all of your stories.
Hope everyone has an enjoyable holiday—look for my 2018 cryptocurrency predictions at some point in the coming week! Just a quick note that I finally sat down and updated the hardware, Linux, and Windows sections of my Ethereum mining guide today, bringing everything up-to-date with current best practices. The Linux setup guide especially deserves your attention if you set up your own rig in the recent past and have noticed a slow degradation in speed over time as the Ethereum DAG file has grown in size. Bitcoin’s value has been increasing steadily over the past 48 hours, hitting new all-time highs nearly hourly—and it doesn’t look like it’s slowing down.
Holidays are a prime opportunity for tech-saavy family members to extol the virtues of cryptocurrency to less technology-literate relatives. It’s not just Bitcoin that’s up—cryptocurrency in general has seen double-digit gains over the past week. I’ve been telling people for months that 2018 will be the year of the five-figure Bitcoin. Bitcoin Cash and Bitcoin Gold forks. Just a quick heads up that the Ethereum network will experience a planned hard fork at some point early tomorrow.
A few of you have emailed me with questions about what you need to do to prepare, and the short answer is that no action is immediately necessary if you’re primarily worried about the continued operation of your miners.

If you have a huge amount of cryptocurrency, you may not trust websites to hold your assets. Who could blame you, with the Mt Gox collapse still relatively fresh in the memory? 70 hardware wallet that the company says has been sold to millions worldwide. 300 byte bit of code that targets the device’s micro-controllers.
One of these stores the private key, and the other acts as a proxy, displaying functions and a USB interface. The latter is far less secure, and can’t tell the difference between genuine firmware and that written by a hacker. That means a preowned wallet could generate fake passwords for new owners, or an attacker could change wallet destinations and payments. Ledger’s chief security officer, Charles Guillemet.
Well, Matt Green, a Johns Hopkins University specialist in encryption security, seems to back Rashid. Ledger is trying to solve a fundamentally hard problem. They need to check the firmware running on a processor. But their secure chip can’t actually see the code running on that processor.
Crypto System Review: Missbräuchlicher Betrug
The number of people in the world who would recognise what the Ledger is, let alone know how to break into one, is vanishingly small. That’s true, but this argument also misses the point altogether. Ledger sells these devices specifically to offer protection against physical access attacks. If that protection is no longer guaranteed, would people still buy the hardware?
At the very least, it’s a helpful reminder that buying certain items preowned can have pretty unfortunate consequences for security, and buying direct or through a legitimate, trusted retailer is the way to go. Even if the companies tell you otherwise, spending a little extra for true peace of mind is a price worth paying. Cyberbullying: What can you do to prevent it?

No longer a fringe fantasy, sex robots are coming to the fore of society. What does this mean for humanity? Enter the characters you see below Sorry, we just need to make sure you’re not a robot. You don’t need to install it to a hard drive because it runs live from RAM. Under the hood it contains a swiss army knife of handy Bitcoin tools that support a wide range of usage models, including a few very secure ones which would otherwise be difficult to perform. We’re avid Bitcoin fans but after going to our first local Bitcoin meetup we discovered the elephant in the room was that there was no easy way to perform cold storage Bitcoin transactions where the wallet lives on an air-gapped system physically disconnected from the Internet.
USB stick with everything you need to perform Bitcoin transactions with as much security as you wanted – including highly secure air-gapped Bitcoin transactions. We’ve documented several common use cases right on this website’s usage section. Click on the various boot modes for instructions. Air-gapped systems raise the bar because they are physically prevented from communicating with the Internet. But like all other security measures air-gaps are no silver bullet, especially when you don’t trust the system behind the air-gap. Not if you don’t want to, or if you just don’t need the extra security.
See the usage section for details. Bitcoin users are getting from their web wallets and Bitcoin phone apps. In terms of security, it can provide equivalent or better security than a hardware wallet, depending on how you use it. In terms of convenience it’s hard to beat a hardware wallet. We call it the If I tell you I’ll have to kill you usage model.
Linguists – General Consideration
We understand that people routinely trade off security for convenience, otherwise they wouldn’t get anything done. We recognize that there is an inescapable trade off between convenience and security and that risk is proportional to the value of your wallet. So it doesn’t make sense to enforce any specific trade off. Also, adding support for locally attached printers so you can print paper wallets. But for a solution to be useful it doesn’t need to be perfect, just better than the alternatives for some use cases.
Unfortunately, the problem is many people currently using Bitcoin don’t understand the risks they are taking and place too much trust on incredibly insecure solutions such as web based Bitcoin wallets, accessed from a general purpose PC that is installed, configured and used by a person who is not and will never be a security expert. That might be OK for very low value wallets that you wouldn’t mind losing but beyond that it is very foolish. CDROMs are naturally read-only and tamper resistant. It expects your flash drive to be vfat formatted. This is the standard format for store bought drives.
USB supports three modes of operation selected from a boot time menu. If the instructions are carefully followed, cold storage modes creates an airgap which ensures that your wallet’s private keys are never loaded into RAM on a computer connected to the Internet. In hot online mode, the private keys are known to a computer connected to the Internet. This is the most convenient mode because you only need one computer. You rely on the magical power of wishful thinking. You’re not important enough to get hacked and any opportunistic malware infection you do get is not going to include any Bitcoin stealing functionailty. Paranoid brainwallet support Hardest to use but leaves no trace of wallet keys in any storage medium.
Your wallet keys are only stored in your head. This workflow is inspired by how Jason Bourne stores his Bitcoin. After generating wallet, you can send Bitcoin to this address. Unfortunately, Warpwallet makes it foolishly easy to skip the part where you input your e-mail as salt. Providing a salt mixes it in with the passphrase you provide. Non-experts may not realize how important this is.
Without the salt, attackers can attempt to crack all Warpwallets simultaneously. With a salt, they have to divide their cracking power amongst a list of suspected e-mails. Using a salt gets you much more security risk free. There are no privacy implications and your e-mail is never exposed anywhere.
In fact, you can use any e-mail you want, as long as you’re sure you won’t forget it. Humans are poor sources of randomness and much more predictable using statistical models than they think. Technology is ever moving forward and cracking techniques always get better, never worse. You may not be familiar with the state of the art, so be extra careful.

The ideal passphrase is 6 to 8 truly random diceware words. If you’re going to try and come up with a random passphrase yourself, be paranoid. They really are out to get you. At least use zxcvbn to measure passphrase strength. It’s not perfect, but it should give you a clue.
You’ll want at least 65 bits of entropy for a salted warpwallet, especially if you are going to be storing funds long-term. DO NOT USE KNOWN PHRASES, QUOTES OR SENTENCES FROM A BOOK. More wallets are lost to routine forgetfulness than sophisticated theft. If you’re not continually accessing your Warpwallet there is a very high likelyhood you will eventually forget your passphrase after a few months or a few years. You only need to forget a single character for your wallet to be lost forever.
Trade War in Focus
This risk needs to be balanced with the risks of making a paper backup. Consider making a paper backup of your passphrase and destroying it only when you are absolutely sure you will not forget it, then use spaced reptition learning to ensure it stays in memory until you want to access the funds. Thanks to Ryan Castellucci for inspiring this section. Insert USB stick where you stored unsigned transaction. Scan qrcode of signed transaction with phone and broadcast transaction to network.
Minimum privilege level policy: for example, if a component doesn’t need network access, don’t give it to it. If a mode doesn’t need network access, enforce lack of network access. Transparency and verifiability: only use open source components who’s integrity can be verified in principle and in which violations of integrity are more likely to be detected. Assume and attempt to compensate for human fallibility: avoid assuming users are advanced Bitcoin and security experts. Do the most to protect them from natural mistakes and lack of awareness with more secure defaults, friendly reminders, health warnings, tools for verifying against mistakes.
See README in source code for specifics. This mode trades off security for the convenience of not having to sign transactions on a separate offline computer. We recommend it for low-medium value wallets. It’s better than storing your wallet on a typical malware infested PC. This mode trades off convenience for the security of keeping your wallet offline in cold storage. Transactions are prepared in cold-online mode and signed in cold-offline mode. This usage model is appropriate for medium-high value Bitcoin wallets.
