Ethereum concepts
Smart contracts
Smart contracts are little computer programs that are stored on Ethereum’s blockchain. They can be activated, or run, by funding them with some ETH. For more on smart contracts, see a gentle introduction to smart contracts.
Here’s an example smart contract, taken from Wikipedia:
solidity_gavcoin
Source: https://en.wikipedia.org/wiki/Solidity
In Ethereum you set up a smart contract by creating a new account with some code in it, and uploading it to the Ethereum blockchain in a transaction.
Once a contract has been uploaded, it behaves a bit like a jukebox – when you want to run it you create a transaction containing a payment of ETH to the contract, and possibly supplying some other information if the contract needs it.
Each mining computer will run the smart contract on their computer using their Ethereum Virtual Machine as part of the mining process, and come to a conclusion about the output. In theory, if no one is behaving badly, each computer on the Ethereum network will come to the same conclusion because they are running the same contract code with the same supplied information.
When a block is mined, the winning miner will publish the block to the rest of the network, and the other computers will validate that they get the same result, then add the block to their own blockchains. This is how the state of Ethereum’s blockchain gets updated.
Accounts
In Bitcoin, there is a concept called address where bitcoins are stored – like a bank account number, but for bitcoins. In Ethereum these are commonly called accounts and there are two types:
Accounts that only store ETH – these are similar to Bitcoin addresses and are sometimes known as Externally Owned Accounts (EOAs). You make payments from these accounts by signing transactions with the appropriate private key.
Here’s an example of an account that stores ETH:
https://etherscan.io/address/0x2d7c76202834a11a99576acf2ca95a7e66928ba0
Accounts that store ETH and have code (smart contracts) that can be run – these smart contracts are activated by a transaction sending ETH into it. Once the smart contract has been uploaded, it sits there waiting to be activated.
Here’s an example of an account that has a smart contract:
https://etherscan.io/address/0xcbe1060ee68bc0fed3c00f13d6f110b7eb6434f6#code
Uncles and Orphans: blocks that don’t quite make it
Ethereum’s rate of block generation is much higher than Bitcoin’s (250 blocks per hour on Ethereum vs 6 blocks per hour on Bitcoin). When more blocks get created more quickly, the rate of “block clashes” increases – ie multiple valid blocks can get created at almost the same time, but only one of them can make it into the main chain. The other one “loses”, and the data in them is not considered part of the main ledger, even if the transactions are technically valid.
In Bitcoin these non-mainchain blocks are called orphans or orphaned blocks and they do not form part of the main chain in any way and are never referenced again by any subsequent blocks.
In Ethereum they are called uncles. Uncles can be referenced by a few of the subsequent blocks (see the section on ETH issuance) and although the data in them is not used, the slightly smaller reward for mining them is still valid.
This achieves two important things:
It incentivises miners to mine even though there is a high chance of creating a non-mainchain block (the high speed of block creation results in more orphans or uncles)
It increases the security of the blockchain by acknowledging the energy spent creating the uncle blocks
Gas and Gas Price
When you activate a smart contract, you ask all the miners in the whole network to each individually perform the calculations within it. This costs them time and energy, and Gas is the mechanism by which you pay them for that service.
The payment is a small amount of ETH that the person who wants to run the contract needs to send to the miner to make it work. This is similar to putting a coin in a jukebox.
Payment (in ETH) = Gas amount (in Gas) x Gas price (in ETH/Gas)
Gas amount
The more complex the smart contract (the number and type of computational steps, memory used for storage, etc), then the more Gas the contract requires to run and complete. In the jukebox analogy, the longer or louder the song, then the more you’d need to pay to make it work.
Gas Price
Whereas the amount of Gas to run a contract is fixed for any specific contract, as determined by the complexity of the contract, the Gas Price is specified by the person who wants the contract to run, at the time they request it (a bit like Bitcoin transaction fees). Each miner will look at how generous the gas price is, and will determine whether they want to run the contract as part of the block. If you want miners to run your contract, you offer a high Gas Price. In this way it’s a competitive auction driven by how much someone is willing to pay to have a contract run.
Why Gas?
Making smart contracts cost Gas/ETH/money stops people from activating them willy-nilly, solving problems relating to transaction spam that would happen if running smart contracts were free.
ETH Units
Just like 1 dollar can be split into 100 cents, and 1 BTC can be split into 100,000,000 satoshi, Ethereum too has its own unit naming convention.
The smallest unit is a wei and there are 1,000,000,000,000,000,000 of them per ETH. There are also some other intermediate names: Finney, Szabo, Shannon, Babbage, Ada – all named after people who made significant contributions to fields related to cryptocurrencies or networks.
Wei and Ether are the two most common denominations.

Smart Contract languages: Solidity / Serpent, LLL
There are three common languages smart contracts are written in, which can be compiled into smart contracts and run on Ethereum Virtual Machines. They are:
Solidity – similar to the language Javascript. This is currently the most popular and functional smart contract scripting language.
Serpent – similar to the language Python, and was popular in the early history of Ethereum.
LLL (Lisp Like Language) – similar to Lisp and was only really used in the very early days. It is probably the hardest to write in.
Ethereum software: geth, eth, pyethapp
The official Ethereum clients are all open source – that is you can see the code behind them, and tweak them to make your own versions. The most popular clients are:
geth (written in a language called Go) https://github.com/ethereum/go-ethereum
eth (written in C++) https://github.com/ethereum/cpp-ethereum
pyethapp (written in Python) https://github.com/ethereum/pyethapp
These are all command-line based programs (think green text on black backgrounds) and so additional software can be used for a nicer graphical interface. Currently the official and most popular graphical one is Mist (https://github.com/ethereum/mist), which runs on top of geth or eth.
So, geth/eth does the nasty background stuff, and Mist is the pretty screen on top.

Given what we know about the moral quality of the Cypherpunks’ struggle against institutional oversight, it’s easy to see why a sense of righteousness might be on display in the most fervent Bitcoin advocacy groups.

Because every transaction published into the blockchain imposes on the network the cost of needing to download and verify it, there is a need for some regulatory mechanism, typically involving transaction fees, to prevent abuse. The default approach, used in Bitcoin, is to have purely voluntary fees, relying on miners to act as the gatekeepers and set dynamic minimums. This approach has been received very favorably in the Bitcoin community particularly because it is 'market-based', allowing supply and demand between miners and transaction senders determine the price. The problem with this line of reasoning is, however, that transaction processing is not a market; although it is intuitively attractive to construe transaction processing as a service that the miner is offering to the sender, in reality every transaction that a miner includes will need to be processed by every node in the network, so the vast majority of the cost of transaction processing is borne by third parties and not the miner that is making the decision of whether or not to include it. Hence, tragedy-of-the-commons problems are very likely to occur.bux bitcoin

Concerns about bitcoin's environmental impact relate bitcoin's energy consumption to carbon emissions. The difficulty of translating the energy consumption into carbon emissions lies in the decentralized nature of bitcoin impeding the localization of miners to examine the electricity mix used. The results of recent studies analyzing bitcoin's carbon footprint vary. A study published in Nature Climate Change in 2018 claims that bitcoin 'could alone produce enough COThis can be done via many smartphone apps, such as the Bitcoin Wallet app by Andreas Schildbach, on Android.

Providing physical products is more difficult as the anonymity is more easily broken when crossing into the physical world: The vendor needs to know where to send the physical goods. Untraceable money makes it possible to ignore some of the laws of the physical world, as the laws cannot be enforced without knowing people's physical identities. For instance, tax on income for online services provided via the crypto-anarchists networks can be avoided if no government knows the identity of the service provider.криптовалюту bitcoin bitcoin india консультации bitcoin bitcoin io кран bitcoin 10 bitcoin пулы bitcoin bitcoin tm bitcoin virus express bitcoin

Within one integrated function, miners validate history, clear transactions and get paid for security on a trustless basis; the integrity of bitcoin’s fixed supply is embedded in its security function, and because the rest of the network independently validates the work, consensus can be reached on a decentralized basis. If a miner completes valid work, it can rely on the fact that it will be paid on a trustless basis. Conversely, if a miner completes invalid work, the rest of the network enforces the rules, essentially withholding payment until valid work is completed. And supply of the currency is baked into validity; if a miner wants to be paid, it must also enforce the fixed supply of the currency, further aligning the entire network. The incentive structure of the currency is so strong that everyone is forced to adhere to the rules, which is the chief facilitator of decentralized consensus.calculator bitcoin bitcoin analysis ethereum node dark bitcoin bitcoin депозит bitcoin group As the blockchain is a trusted peer-to-peer network,adbc bitcoin bitcoin расшифровка
