How is Ethereum similar to Bitcoin?
I think it’s easiest to understand Ethereum by exploring the similarities and differences between Ethereum and a simpler system, Bitcoin. So what are the similarities?
Ethereum has a blockchain
Like Bitcoin, Ethereum has a blockchain, which contains blocks of data (transactions and smart contracts). The blocks are created or mined by some participants and distributed to other participants who validate them.
You can explore this blockchain here: https://etherscan.io
Blocks form a chain by referring to the hash or fingerprint of the previous block. See a gentle introduction to blockchain technology for a primer.
Ethereum is public and permissionless
Like Bitcoin, the main Ethereum network is a public, permissionless network – ie anyone can download or write some software to connect to the network and start creating transactions and smart contracts, validating them, and mining blocks without needing to log in or sign up with any other organisation.
In general, when people talk about Ethereum they mean the main public permissionless instance (version) of the network. However, like Bitcoin, you can take Ethereum software, modify it slightly and create private networks that aren’t connected to the main public network. The private tokens and smart contracts won’t be compatible with the public tokens though, for now. For more on the difference between public permissionless and private permissioned networks, see confused by blockchains? Revolution vs Evolution
Ethereum has Proof-of-Work (PoW) mining
Like Bitcoin, mining participants create valid blocks by spending electricity to find solutions to a mathematical puzzle. Ethereum’s PoW maths challenge called Ethash works slightly differently to Bitcoin’s, and this allows common hardware to be used for mining. This reduces the efficiency edge of task-specific hardware known as ASICs, which are common in Bitcoin mining.
For more on mining see a gentle introduction to bitcoin mining.
On Ethereum’s roadmap there is a plan to move from electricity-expensive Proof-of-Work mining to a more energy-efficient Proof-of-Stake protocol called Casper, in a future release of the Ethereum software called Serenity.
Ethereum has an inbuilt cryptocurrency
Ethereum’s token is called Ether, shortened to ETH. This is a cryptocurrency that can be traded for other cryptocurrencies or other sovereign currencies, just like BTC. Its current value is around US$13 per ETH token (Oct 2016). Token ownership is tracked on the Ethereum blockchain, just like BTC ownership is tracked on Bitcoin’s blockchain, though at a technical level they track them in slightly different ways.
For more on cryptocurrencies and tokens see a gentle introduction to digital tokens.
This is where the action’s really at. Application Specific Integrated Circuits (ASICs) are specifically designed to do just one thing: mine bitcoins at mind-crushing speeds, with relatively low power consumption. Because these chips have to be designed specifically for that task and then fabricated, they are expensive and time-consuming to produce – but the speeds are stunning. At the time of writing, units are selling with speeds anywhere from 5-500 GH/sec (although actually getting some of them to ship has been a problem). Vendors are already promising ASIC devices with far more power, stretching up into the 2 TH/sec range.bot bitcoin bitcoin bat bitcoin видео

If you want to index your currency to that of another state, you either become its monetary vassal, or you undertake the herculean task of stopping your citizens from exporting funds abroad.ферма ethereum blacktrail bitcoin мастернода bitcoin kupit bitcoin options bitcoin ethereum swarm bitcoin plugin bitcoin gpu криптовалют ethereum bitcoin games майнинг monero ставки bitcoin amazon bitcoin home bitcoin ethereum raiden bitcoin neteller coinmarketcap bitcoin bitcoin 2017 bitcoin описание bitcoin vizit wallet cryptocurrency

This is what made creating the block so difficult; a hash that begins with many zeros is much more difficult to find than a hash with few or no zeros. The computer that generated this block had to try many Nonce values (also listed on the block's page) until it found one that generated this run of zeros. Next, see the line titled Previous block. Each block contains the hash of the block that came before it. This is what forms the chain of blocks. Now take a look at all the transactions the block contains. The first transaction is the income earned by the computer that generated this block. It includes a fixed amount of coins created out of 'thin air' and possibly a fee collected from other transactions in the same block.putin bitcoin bitcoin china bitcoin пополнить майнер bitcoin secp256k1 ethereum приложение tether security bitcoin bitcoin update monero wallet

bitcoin начало дешевеет bitcoin Also, be sure you are in a country where bitcoins and bitcoin mining is legal.In all perceived-to-be successful applications today, money is issued by a central bank; it is relatively stable and capable of near infinite transaction throughput; it facilitates day-to-day commerce; and by the grace of god, its supply can be rapidly inflated to meet the needs of an ever-changing economy. Bitcoin has none of these traits (some not presently, others not ever), and as a result, it is most often dismissed as not meeting the standards of modern-day money. This is where overthinking a problem can cripple the highest of IQs. Pattern recognition fails because the game fundamentally changed, but the players do not yet realize it. It is akin to getting lost in the weeds or failing to see the forest through the trees. Bitcoin is finitely scarce, it is highly divisible and it is capable of being sent over a communication channel (and on a permissionless basis). There will only ever be 21 million bitcoin. Rocket scientists and the most revered investors of our time could look at this equation relative to other applications in the market and be confounded, not seeing its value. While at the same time, if posed with a very simple question, would you rather be paid either in a currency with a fixed supply that cannot be manipulated or in a currency that is subject to persistent, systemic and significant debasement, an overwhelming majority of individuals would choose the former all day, every day.cubits bitcoin bitcoin терминалы майнер monero wikipedia bitcoin bitcoin explorer bitcoin asic bitcoin microsoft usb bitcoin hardware bitcoin дешевеет bitcoin carding bitcoin ethereum алгоритм адрес ethereum bitcoin rt bitcoin кошелек moto bitcoin ethereum метрополис bitcoin change криптовалюта monero twitter bitcoin bitcoin cny калькулятор bitcoin bitcoin спекуляция bitcoin neteller bitcoin рубль bazar bitcoin падение ethereum bitcoin loan wifi tether dat bitcoin transaction bitcoin bitcoin gold mine ethereum пополнить bitcoin bitcoin currency bitcoin wm bitcoin easy nxt cryptocurrency gadget bitcoin transactions bitcoin calculator cryptocurrency asics bitcoin продажа bitcoin bitcoin рублях
