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.

bitcoin вход status bitcoin bitcoin puzzle bitcoin skrill bitcoin bitrix Although technically transactions occur instantaneously on both the Bitcoin and Litecoin networks, time is required for those transactions to be confirmed by other network participants. Litecoin was founded with the goal of prioritizing transaction speed, and that has proven an advantage as it has grown in popularity. According to data from Blockchain.info, the Bitcoin network’s average transaction confirmation time is currently just under 9 minutes per transaction (the time it takes for a block to be verified and added to the blockchain), though this can vary widely when traffic is high.10 The equivalent figure for Litecoin is roughly 2.5 minutes.11 In principle, this difference in confirmation time could make Litecoin more attractive for merchants. For example, a merchant selling a product in exchange for Bitcoin would need to wait nearly four times as long to confirm payment as if that same product were sold in exchange for Litecoin. On the other hand, merchants can always opt to accept transactions without waiting for any confirmation at all. The security of such zero-confirmation transactions is the subject of some debate.12халява bitcoin

Authorities, including the European Banking Authority, the FBI, South African Reserve Bank and the Financial Action Task Force of the G7 have expressed concerns that bitcoin may be used for money laundering. In early 2014, an operator of a U.S. bitcoin exchange, Charlie Shrem, was arrested for money laundering. Subsequently, he was sentenced to two years in prison for 'aiding and abetting an unlicensed money transmitting business'. Alexander Vinnik, an alleged owner of BTC-e was arrested in Greece July 25 of 2017 on $4 billion money laundering charges for flouting anti-money laundering (AML) laws of the US. A report by the UK's Treasury and Home Office named 'UK national risk assessment of money laundering and terrorist financing' (2015 October) found that, of the twelve methods examined in the report, bitcoin carries the lowest risk of being used for money laundering, with the most common money laundering method being the banks.кошельки ethereum bitcoin 3d bistler bitcoin monero hardware

Then, when the price drops again, you can buy back your ETH and repeat the cycle to lock in more profits.Today intermediaries are everywhere.
