By now you've probably heard about the cryptocurrency craze. Either a family member, friend, neighbor, doctor, Uber driver, sales associate, server, barista, or passer-by on the street, has probably told you how he or she is getting rich quick with virtual currencies like bitcoin, Ethereum, Ripple, or one of the lesser-known 1,300-plus investable cryptocurrencies.
But how much do you really know about them? Considering just how many questions I've received out of the blue from the aforementioned group of people over the last month, the answer is probably, "not a lot."
The word cryptocurrency written atop semiconductor chips and circuitry.

Today, we'll change that. We're going to walk through the basics of cryptocurrencies, step by step, and explain things in plain English. No crazy technical jargon here. Just sticks and stones examples of how today's cryptocurrencies work, what they're ultimately trying to accomplish, and how they're being valued.
Let's get started.
What are cryptocurrencies?
Simply put, cryptocurrencies are electronic peer-to-peer currencies. They don't physically exist. You can't pick up a bitcoin and hold it in your hand, or pull one out of your wallet. But just because you can't physically hold a bitcoin, it doesn't mean they aren't worth anything, as you've probably noticed by the rapidly rising prices of virtual currencies over the past couples of months.
How many cryptocurrencies are there?
The number is always changing, but according to CoinMarketCap.com as of Dec. 30, there were around 1,375 different virtual coins that investors could potentially buy. It's worth noting that the barrier to entry is particularly low among cryptocurrencies. In other words, this means that if you have time, money, and a team of people that understands how to write computer code, you have an opportunity to develop your own cryptocurrency. It likely means new cryptocurrencies will continue entering the space as time passes.
Why were cryptocurrencies invented?
Technically, the idea of an electronic peer-to-peer currency was being tinkered with decades ago, but it wasn't truly successful until 2008, when bitcoin was conceived. The basis of bitcoin's creation, and all virtual currencies that have since followed, was to fix a number of perceived flaws with the way money is transmitted from one party to another.
What flaws? For example, think about how long it can take for a bank to settle a cross-border payment, or how financial institutions have been reaping the rewards of fees by acting as a third-party middleman during transactions. Cryptocurrencies work around the traditional financial system through the use of blockchain technology.

wiki ethereum bitcoin code bitcoin grant кошельки bitcoin Once step (1) has taken place, after a few minutes some miner will include the transaction in a block, say block number 270. After about one hour, five more blocks will have been added to the chain after that block, with each of those blocks indirectly pointing to the transaction and thus 'confirming' it. At this point, the merchant will accept the payment as finalized and deliver the product; since we are assuming this is a digital good, delivery is instant. Now, the attacker creates another transaction sending the 100 BTC to himself. If the attacker simply releases it into the wild, the transaction will not be processed; miners will attempt to run APPLY(S,TX) and notice that TX consumes a UTXO which is no longer in the state. So instead, the attacker creates a 'fork' of the blockchain, starting by mining another version of block 270 pointing to the same block 269 as a parent but with the new transaction in place of the old one. Because the block data is different, this requires redoing the proof of work. Furthermore, the attacker's new version of block 270 has a different hash, so the original blocks 271 to 275 do not 'point' to it; thus, the original chain and the attacker's new chain are completely separate. The rule is that in a fork the longest blockchain is taken to be the truth, and so legitimate miners will work on the 275 chain while the attacker alone is working on the 270 chain. In order for the attacker to make his blockchain the longest, he would need to have more computational power than the rest of the network combined in order to catch up (hence, '51% attack').вклады bitcoin ethereum news 1000 bitcoin bitcoin рейтинг создатель bitcoin
