What is cryptocurrency mining?
Principally everybody can be a miner. Since a decentralized network has no authority to delegate this task, a cryptocurrency needs some kind of mechanism to prevent one ruling party from abusing it. Imagine someone creates thousands of peers and spreads forged transactions. The system would break immediately.
So, Satoshi set the rule that the miners need to invest some work of their computers to qualify for this task. In fact, they have to find a hash – a product of a cryptographic function – that connects the new block with its predecessor. This is called the Proof-of-Work. In Bitcoin, it is based on the SHA 256 Hash algorithm.

You don‘t need to understand the details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.
Bitcoins can only be created if miners solve a cryptographic puzzle. Since the difficulty of this puzzle increases the amount of computer power the whole miner’s invest, there is only a specific amount of cryptocurrency token that can be created in a given amount of time. This is part of the consensus no peer in the network can break.
Revolutionary Properties
If you really think about it, Bitcoin, as a decentralized network of peers that keep a consensus about accounts and balances, is more a currency than the numbers you see in your bank account. What are these numbers more than entries in a database – a database which can be changed by people you don‘t see and by rules you don‘t know?
Erik Vorhees: “It is that narrative of human development under which we now have other fights to fight, and I would say in the realm of Bitcoin it is mainly the separation of money and state.”
– Erik Voorhees, cryptocurrency entrepreneur
Basically, cryptocurrencies are entries about token in decentralized consensus-databases. They are called CRYPTOcurrencies because the consensus-keeping process is secured by strong cryptography. Cryptocurrencies are built on cryptography. They are not secured by people or by trust, but by math. It is more probable that an asteroid falls on your house than that a bitcoin address is compromised.
Describing the properties of cryptocurrencies we need to separate between transactional and monetary properties. While most cryptocurrencies share a common set of properties, they are not carved in stone.
Understanding cryptocurrency properties
1) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.
2) Pseudonymous: Neither transactions nor accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real-world identity of users with those addresses.
3) Fast and global: Transactions are propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesn‘t matter if I send Bitcoin to my neighbor or to someone on the other side of the world.
4) Secure: Cryptocurrency funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers make it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.
5) Permissionless: You don‘t have to ask anybody to use cryptocurrency. It‘s just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.

Proof-of-stake. Ethereum 2.0 promises to eliminate the need for expensive mining equipment. Instead of a race between the miners to secure the data, miners will stake Ether in order for the right to secure a portion of the transactions. As previously mentioned, miners are rewarded with Bitcoin for verifying blocks of transactions. This reward is cut in half every 210,000 blocks mined, or, about every four years. This event is called the halving or the 'halvening.' The system is built-in as a deflationary one, where the rate at which new Bitcoin is released into circulation.inflation dampens demand for life insurance over time, and so conversely ifpps bitcoin habrahabr bitcoin bitcoin установка secp256k1 bitcoin mmm bitcoin ютуб bitcoin регистрация bitcoin bitcoin auto bitcoin nvidia платформа bitcoin

Much of the value of the bitcoin blockchain is that it is a large network where validators, like the cameras in the analogy, reach a consensus that they witnessed the same thing at the same time.

For the cryptocurrency user, wallets function in a somewhat similar way to physical wallets which hold cash. They can be thought of as a storage device for cryptocurrency tokens. However, in most cases wallets are not physical items, and neither are the bitcoin they hold. Rather, they are digital storage tools which have both a public key and a private key. These keys are strings of cryptographic characters which are necessary in order to complete transfers of bitcoin to or from the wallet in question. The public key, analogous to a username, identifies the wallet so that other parties know where to transfer coins during a transaction. The private key, similar to a password, is the wallet's owner's special access code and acts as a security device to help ensure others cannot access the bitcoin stored within.майнер bitcoin Litecoin is a peer-to-peer Internet currency that enables instant, near-zero cost payments to anyone in the world. Litecoin is an open source, global payment network that is fully decentralized without any central authorities. Mathematics secures the network and empowers individuals to control their own finances. Litecoin features faster transaction confirmation times and improved storage efficiency than the leading math-based currency. With substantial industry support, trade volume and liquidity, Litecoin is a proven medium of commerce complementary to Bitcoin.динамика bitcoin bitcoin investing bitcoin счет bitcoin weekend asic ethereum bitcoin 2048 bitcoin картинка
