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.

monero ico The second point is important. Usually, banks are in charge of keeping accurate records of digital transactions. They ensure that money isn’t created out of thin air, and that users don’t cheat and spend their money more than once.ETH is digital, global money.Because it generates blocks about four times faster than Bitcoin, Litecoin can confirm the legitimacy of transactions more quickly and process more transactions in the same timeframe.ethereum faucet кошелек tether poloniex monero платформы ethereum zcash bitcoin Bitcoin is an adaptive and evolving system; it is not static. No one controls the network and there are no leaders capable of forcing changes onto the network. It is decentralized at every layer, and as a result, it has shown to be immune to any type of attack. However, it is not just immune to attack or errors, bitcoin actually becomes stronger as: i) external forces attempt to influence or coopt the network; ii) as individuals within the network make errors; and, iii) as a very function of its volatility, which is often perceived to be a limiting, if not critical, flaw. As bitcoin survives shocks and as individuals learn from errors and adapt to its volatility, bitcoin becomes tangibly more reliable; its demonstration of resilience and immunity causes trust to be reinforced in the network, which increases adoption and makes bitcoin more resistant to future attack or individual errors. It is a positive, self-reinforcing feedback loop. With every failed attempt to coopt or coerce the network, the bitcoin protocol hardens and confidence increases. Every time bitcoin doesn’t die, that very event propels bitcoin forward, and in a fundamentally stronger state than previously existed.bitcoin sec bitcoin kazanma bitcoin knots cudaminer bitcoin bitcoin доходность ethereum farm ethereum майнеры котировки bitcoin

Established names, such as Goldman Sachs (GS), are conspicuously absent from the list of names offering cryptocurrency solutions. Their entry could shake up the nascent market. Some of that is already happening with Coinbase and Fidelity Investments taking the lead in offering or designing cryptocurrency custody services. ShareThe main problem with all these schemes is that proof of work schemes depend on computer architecture, not just an abstract mathematics based on an abstract 'compute cycle.' (I wrote about this obscurely several years ago.) Thus, it might be possible to be a very low cost producer (by several orders of magnitude) and swamp the market with bit gold. However, since bit gold is timestamped, the time created as well as the mathematical difficulty of the work can be automatically proven. From this, it can usually be inferred what the cost of producing during that time period was.Before we can understand cold storage, we must first explore the concept of a bitcoin wallet. 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.monero новости earn bitcoin добыча ethereum

For financial contracts for difference, it may actually be possible to decentralize the data feed via a protocol called SchellingCoin. SchellingCoin basically works as follows: N parties all put into the system the value of a given datum (eg. the ETH/USD price), the values are sorted, and everyone between the 25th and 75th percentile gets one token as a reward. Everyone has the incentive to provide the answer that everyone else will provide, and the only value that a large number of players can realistically agree on is the obvious default: the truth. This creates a decentralized protocol that can theoretically provide any number of values, including the ETH/USD price, the temperature in Berlin or even the result of a particular hard computation.loco bitcoin monero pool знак bitcoin казино ethereum bitcoin click hash bitcoin вложения bitcoin total cryptocurrency продажа bitcoin bitcoin nedir bitcoin code

It can be tempting to join the biggest pool since it likely offers the greatest chance of finding blocks frequently and turning a profit. If your pool reaches half the network's hashing power, though, it represents a risk to the litecoin network itself. The pool likely has no incentive to carry out a 51% attack itself – that would erode confidence in litecoin and hurt the price – but, as Lee points out, 'with centralized mining, then there are a few parties where governments or malicious entities can actually approach those parties and coerce them into doing something bad for the coin.'ethereum clix bitcoin комиссия капитализация bitcoin amazon bitcoin amazon bitcoin bitcoin wmx ethereum supernova keepkey bitcoin email bitcoin шахта bitcoin bitcoin nvidia bitcoin япония

On 5 December 2013, the People's Bank of China prohibited Chinese financial institutions from using bitcoins. After the announcement, the value of bitcoins dropped, and Baidu no longer accepted bitcoins for certain services.
