The text was updated successfully, but these errors were encountered:. Hi Milos19, the same thing happened to me. I opened my wallet last night, tried to send bitcoin and was prompted with an update box.

I checked Electrum. This is in order to prevent user exposure to phishing messages. Do not download Electrum from any another source than electrum. So when I saw the prompt asking me to update to 4. It showed my wallet transferring 0. Many wont know that they have sent it to a scammer, because it mimics your account and even makes it look like you are doing everything correct.

Sorry, something went wrong. Over the months, since we have learned about the issue , we have done many things to mitigate it, as best as possible. A lot of time was spent on this. This mitigation when it was first deployed turned out to be extremely effective. Unfortunately around 2 weeks later, the attacker s started a massive DDOS against all honest servers as a countermeasure so that they cannot keep crashing the old clients. This DDOS is still ongoing.

Almost all server operators have been notified that they should upgrade if possible, to take advantage of 1 and 4 ; and later 2. We are constantly identifying evil servers, and checking what URLs they are sending their victims to.

There are two categories: GitHub repositories, and domain names. As soon as we detect the first, we are notifying GitHub to take down the malicious repo, and they do take it down fairly soon. When detecting the latter, we send reports to the domain registrar, and depending on their cooperation, take down those domain. In case of domains, we also report them to Google Safe Browsing. These announcements are signed, so they cannot be spoofed. I appreciate your comment, although too many have been hurt.

I am deleting "the safest offline wallet" from my PC as its too dangerous. Sorry, but many lost their retirement funds today, their kids university money, their house deposits. Crypto is for the stupid and the hackers, not the general person. I wanted to ask if my computer is still at risk. Other bank accounts, other electronic wallets, etc. Thank you. What about e-police. As all exchanges require ID confirmation, hacker might be not so smart and just cash out the money.

Maybe they have insurance or something, like binance had? We did not leave a hole in our system; the vulnerability was patched as soon as it was discovered. Please understand that if we had the power to trigger software upgrades automatically, we would also have the power to steal bitcoins from our users.

That is not what we want; we are a software provider, not a bank. Any person who has lost bitcoins because of phishing or malware should report it to the police and please inform us about it. I ve reported to the FBI expecting that helps, at least by finding the criminals. They stole me 0. With the current trend of btc going up, it makes me even worse. I waited for almost 2 years before the trend turns and now everything is gone.

There should be an API where you could report on stolen bitcoin. Merchants and exchange could use this api to discard transactions originating from stolen funds. This is however, not something electrum should develop. But what about other electronic wallets? Today I noticed that all of the Bittrex foreign exchange was gone.

Is it possible for them to steal these, too? I have already sent a question to Bittrex but so far no answer. With great delay, I learned about the theft of 16 bitcoins!!! Circumstances look mystical, because to uncomment a clean comparative system was unlikely due to a rare inclusion. This is more than a nightmare loss, doubly offensive from the fact that the criminal appropriated the coins.

В году во время краха денежной промышленности - и, может быть, чрезвычайно кстати - никому не узнаваемый Сатоши Накамото сделал документ - протокол для цифровой валюты с внедрением базисной криптовалюты , названной Биткойн. Эта криптовалюта дозволила обеспечить надёжность и оперировать без посредников. In an ICO campaign, a percentage of the cryptocurrency usually in the form of "tokens" is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.

В ЧЕМ ОТЛИЧИЕ КРИПТОВАЛЮТ

The Bitcoin reward that miners receive is an incentive that motivates people to assist in the primary purpose of mining: to legitimize and monitor Bitcoin transactions, ensuring their validity. Because these responsibilities are spread among many users all over the world, Bitcoin is a "decentralized" cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation. Miners are getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions.

By verifying transactions, miners are helping to prevent the " double-spending problem. Double spending is a scenario in which a Bitcoin owner illicitly spends the same bitcoin twice. While there is the possibility of counterfeit cash being made, it is not exactly the same as literally spending the same dollar twice. With digital currency, however, as the Investopedia dictionary explains, "there is a risk that the holder could make a copy of the digital token and send it to a merchant or another party while retaining the original.

What a Bitcoin miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice. Only 1 megabyte of transaction data can fit into a single bitcoin block.

The 1 MB limit was set by Satoshi Nakamoto, and this has become a matter of controversy as some miners believe the block size should be increased to accommodate more data, which would effectively mean that the bitcoin network could process and verify transactions more quickly. That is correct.

To earn bitcoins, you need to be the first miner to arrive at the right answer, or closest answer, to a numeric problem. This process is also known as proof of work PoW. The good news: No advanced math or computation is really involved.

And the number of possible solutions only increases the more miners that join the mining network known as the mining difficulty. In order to solve a problem first, miners need a lot of computing power. Other web resources offer similar tools.

In addition to lining the pockets of miners and supporting the Bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of September , there were around Aside from the coins minted via the genesis block the very first block, which was created by founder Satoshi Nakamoto , every single one of those bitcoins came into being because of miners.

In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. This does not mean that transactions will cease to be verified. Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol.

In other words, miners have some degree of influence on the decision-making process on such matters as forking. The rewards for Bitcoin mining are reduced by half roughly every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC. By , this was halved again to On May 11, , the reward halved again to 6.

Not a bad incentive to solve that complex hash problem detailed above, it might seem. If you want to keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real-time. Interestingly, the market price of Bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and historically the price has risen with it.

If you are interested in seeing how many blocks have been mined thus far, there are several sites, including Blockchain. The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks.

When there is more computing power collectively working to mine for bitcoins, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases.

All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC. Some miners—particularly Ethereum miners—buy individual graphics cards GPUs as a low-cost way to cobble together mining operations.

And there is no limit to how many guesses they get. If B and C both answer simultaneously, then the analogy breaks down. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block.

Here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? The decimal system uses as its base factors of e. This, in turn, means that every digit of a multi-digit number has possibilities, zero through ninety-nine. In computing, the decimal system is simplified to base 10, or zero through nine.

In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. If you are mining Bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash. Remember that analogy, where the number 19 was written on a piece of paper and put it in a sealed envelope?

In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many " nonces " as possible, as fast as possible. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.

In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that? The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block was mined.

The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block.

If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with a string of leading zeroes. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:. The winning hash for a bitcoin miner is one that has at least the minimum number of leading zeroes defined the mining difficulty. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:.

To find such a hash value, you have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined Bitcoin. Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings. A disproportionately large number of blocks are mined by pools rather than by individual miners. You cannot guess the pattern or make a prediction based on previous target hashes.

Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem. They must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution. All told, Bitcoin mining is largely unprofitable for most individual miners as of this writing.

The site Cryptocompare offers a helpful calculator that allows you to plug in numbers such as your hash speed and electricity costs to estimate the costs and benefits. Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own.

For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. The protocol established by Satoshi Nakamoto dictates that only 21 million bitcoins can ever be mined -- about 12 million have been mined so far -- so there is a limited supply, like with gold and other precious metals, but no real intrinsic value.

There are numerous mathematical and economic theories about why Nakamoto chose the number 21 million. Without a government or central authority at the helm, controlling supply, "value" is totally open to interpretation.

Bitcoin has made Satoshi Nakamoto a billionaire many times over, at least on paper. Getting started is about as complicated as setting up a Paypal account. With Coinbase, for example, you can use your bank or Paypal account to make a deposit into a virtual wallet, of which there are many to choose from. Once your account is funded, which usually takes a few days, you can then exchange traditional currency for bitcoin. You can use bitcoin to buy things from more than , merchants , though still few major ones.

You can sell it. Or you can just hang on to it. Note that there are no inherent transaction fees with bitcoin, although exchanges like Coinbase typically charge a fee when you buy or sell. For instance, bitcoin was the sole currency accepted on Silk Road, the Dark Web marketplace for drugs and other illicit goods and services that was shuttered by the FBI in Legal and regulatory hazards aside, as both an investment and currency, bitcoin is very risky.

When you wake up in the morning, you know pretty precisely how much a dollar can buy. The financial value of a bitcoin, however, is highly volatile and may swing widely from day to day and even hour to hour. Exhibit A: December Bitcoin transactions cannot be traced back individuals -- they are secured but also obscured through the use of public and private encryption keys. This anonymity can be appealing, especially with companies and marketers increasingly tracking our every purchase, but it also comes with drawbacks.

You can never be certain who is selling you bitcoin or buying them from you. Opportunities for money laundering abound; in , authorities in the Netherlands arrested 10 men for just this. Theft is also a risk. There are few avenues for pursuing refunds, challenging a transaction or recovering such losses. Because bitcoin is so new and decentralized, there is plenty of murkiness and many unknowns.

Even the technical rules for mining are still evolving and up for debate. The IRS views bitcoins as property, not currency. Even Coinbase, the most established of them all has struggled to keep up with demand, plagued by site outages, scaling issues and customer service complaints. In August , different sects within the bitcoin mining community had a disagreement about the rules governing the mining process -- specifically, what constitutes the appropriate size in megabytes of a block.

Unable to form a consensus, there was a fork in the blockchain , with the bitcoin originalists going one way and the group favoring larger blocks going another to start Bitcoin Cash. Though they share a common digital ancestry, each now has its own individual blockchain with slightly different protocols. Forking is almost assured to happen again in the future. More than a thousand , with more sprouting up every day.
