OK, what the heck is blockchain?
Blockchain is the digital ledger where all transactions involving a virtual currency are stored. If you buy bitcoin, sell bitcoin, use your bitcoin to buy a Subway sandwich, and so on, it'll be recorded, in an encrypted fashion, in this digital ledger. The same goes for other cryptocurrencies.
Think of blockchain technology as the infrastructure that underlies virtual coins. It's the foundation of your home, while the tethered virtual coin represents all the products built on top of that foundation.
Why is blockchain a potentially better choice than the current system of transferring money?
Blockchain offers a number of potential advantages, but is designed to cure three major problems with the current money transmittance system.
First, blockchain technology is decentralized. In simple terms, this just means there isn't a data center where all transaction data is stored. Instead, data from this digital ledger is stored on hard drives and servers all over the globe. The reason this is done is twofold: 1.) it ensures that no one person or company will have central authority over a virtual currency, and 2.) it acts as a safeguard against cyberattacks, such that criminals aren't able to gain control of a cryptocurrency and exploit its holders.
Secondly, as noted, there's no middleman with blockchain technology. Since no third-party bank is needed to oversee these transactions, the thought is that transaction fees might be lower than they currently are.
Finally, transactions on blockchain networks may have the opportunity to settle considerably faster than traditional networks. Let's remember that banks have pretty rigid working hours, and they're closed at least one or two days a week. And, as noted, cross-border transactions can be held for days while funds are verified. With blockchain, this verification of transactions is always ongoing, which means the opportunity to settle transactions much more quickly, or perhaps even instantly.

How are transactions verified on a blockchain?
You might be wondering how these blockchain transactions are verified. After all, there are logistics involved, such as making sure that the same virtual coin isn't being spent twice. Often this verification falls onto a group of folks known as "miners."
Cryptocurrency miners are nothing more than people with high-powered computers who are competing against other people with high-powered computers to solve complex math equations. These equations are a product of the encryption designed to protect transaction data on the digital ledger.
The first miner to solve these equations, and in the process verify transactions on the ledger, gets a reward, which is known as a "block reward." This reward is paid out in virtual coins, and is an example of how bitcoin transactions are verified. This process is referred to as "proof of work."
The only other major verification process in place is known as "proof of stake." Instead of having people use tons of resources trying to solve complex equations to verify transactions, the proof of stake model chooses who gets to verify the next block of transactions based on their ownership in a virtual currency. In essence, the more you own, the better chance you have of getting to verify transactions. With proof of stake, there is no competition among your peers and no excessive energy usage while solving complex equations, which can make it much more cost-effective.
The proof of stake model also rewards those folks who verify transactions differently. Instead of being paid in virtual coins, the stakeholder earns the transaction fees tied to that block of transactions.

Are blockchain networks public or private?
The interesting thing is that blockchain has the opportunity to be public or private. As you might imagine, a private blockchain would appeal most to businesses, while public blockchains are most appealing to consumers who might want to use their virtual currency to buy goods or services, or to cryptocurrency investors.
A private blockchain, just as it sounds, allows a business to place restrictions on who has access to data, and who can make transactions on the network. Meanwhile, public blockchains allow anyone to join and participate. Bitcoin is an example of a public blockchain.
Is it true that cryptocurrency transactions are anonymous?
The answer to this is, "it depends." Most cryptocurrencies aren't as anonymous as you'd think. Sure, you don't have to supply your Social Security number or bank account to begin trading or investing in cryptocurrencies, but any transaction you make is still going to be recorded in the underlying digital ledger.
Recently, the Internal Revenue Service (IRS) won a court case against cryptocurrency exchange Coinbase that required the exchange to turn over information on 14,355 users who, between 2013 and 2015, exchanged at least $20,000 worth of bitcoin. While the IRS primarily sought this info to go after possible capital-gain tax evaders, the bigger idea here is that these transactions aren't as anonymous as you'd think.
There is, however, a group of cryptocurrencies known "privacy coins" that have a sole purpose of beefing up the anonymity and privacy of a transaction. They use specialized protocols to help hide the identity of the sender of a payment. Monero and Dash are examples of coins that belong to this specialized group.

How do virtual coins fit into all of this?
As noted, digital currencies are what investors are buying. In nearly all instances, buying a cryptocurrency won't give an investor any ownership in the underlying blockchain technology. This happens to be one of the biggest differences between cryptocurrencies and traditional investments, like stocks. If you buy stock in a publicly traded company, you own a fractional percentage of that business. That's not the case with nearly all cryptocurrencies.
So, what do the virtual coins do exactly? In many instances, the coins are required to pay for transactions fees on a blockchain. Ethereum, which is one of the largest cryptocurrencies by market cap behind bitcoin, requires users of its blockchain to pay transaction fees in its coin, known as Ether. But there are other potential applications.
For example, Ripple's coin, known as the XRP, may serve as an intermediary that'll allow transactions to settle faster. Ripple is a blockchain company that's focused on partnering with big banks and financial institutions. Imagine that a customer in Japan wants to make a payment to a business in the U.K. If this payment were routed through Ripple's blockchain, it could take the payment in Japanese yen, convert that payment into XRP coins, then convert those coins into British pounds. All of this could theoretically be done instantly, or at the very least considerably faster than traditional banks (and hopefully for a lower cost).
How should cryptocurrencies be valued?
Truth be told, no one knows the answer to this, because it's dependent on a number of factors. These include:
How quickly blockchain technology is adopted by bigger businesses;
How quickly merchants are willing to accept virtual currencies as a form of payment;
Whether governments around the world will accept cryptocurrencies as legal tender, or choose to ban them entirely.
It's also unclear at times how cohesive a virtual coin and its underlying blockchain are. The example above involving Ripple's blockchain and its XRP shows how the two work pretty well hand-in-hand. Not all cryptocurrencies have a coin that has a clear-cut use or enhances the value of its underlying blockchain. This is why valuing cryptocurrencies often proves difficult.

Why have cryptocurrencies gone up so much?
Again, there's no 100% correct answer here, but the key in their success remains two factors. First, retail investors (i.e., non-professional investors) have accounted for most virtual currency trading. Institutional investors have kept to the sidelines because either their company won't allow them to invest in cryptocurrencies, or they're simply too volatile to merit an investment. Retail investors tend to be more reliant on their emotions relative to institutional investors, leading to moves that tend to overshoot to the upside, and downside.
The second factor is that this isn't exactly a "fair" market. Among traditional equities, like the stock market, an investor has the opportunity to buy, sell, and even bet against an equity. Money can be made if an equity moves up or down. With nearly all cryptocurrencies, except bitcoin, buying or selling is the only option. There is no way to make money if a cryptocurrency goes down, which naturally tends to incentivize buying. This probably won't last forever, but it's played a key role in pushing prices higher.

client ethereum bitcoin отзывы bitcoin cgminer Far from being a novelty or prototype, Bitcoin has shown itself to be a threatening alternative to present-day organizational conventions and to the large commercial businesses that rely on them. It may spur a radical unbundling of corporate business as it lowers transaction costs for the institutions that adopt it. While the effects of such unbundling are unpredictable, value seems most likely to accumulate in cryptocurrency services businesses; in hardware makers and operators that rent computing resources to the network; and in building businesses on the layer 2 networks.'The requirement for a central server became the Achilles’ heel of digital cash. While it is possible to distribute this single point of failure by replacing the central server’s signature with a threshold signature of several signers, it is important for auditability that the signers be distinct 10 and identifiable. This still leaves the system vulnerable to failure, since each signer can fail, or be made to fail, one by one.'secp256k1 bitcoin ethereum asic sell ethereum проекта ethereum tether coin torrent bitcoin bitcoin change bitcoin шахты bitcoin ключи space bitcoin
