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/*****p-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.
Bitcoin is not an official currency. That said, most jurisdictions still require you to pay income, sales, payroll, and capital gains taxes on anything that has value, including bitcoins. It is your responsibility to ensure that you adhere to tax and other legal or regulatory mandates issued by your government and/or local municipalities.Why is cryptocurrency the future of finance?Suppose person A wants to pay person B 10 ethers. The transaction will be sent to the EVM using a smart contract for a fund transfer from A to B. To validate the transaction; the Ethereum network will perform the proof-of-work consensus algorithm.bitcoin bux bitcoin 20 займ bitcoin

microsoft ethereum As noted, digital currencies are what investors are buying. In nearly all instances, buying a cryptocurrency won't give an investor any ownership in the underlying blockchain technology. This happens to be one of the biggest differences between cryptocurrencies and traditional investments, like stocks. If you buy stock in a publicly traded company, you own a fractional percentage of that business. That's not the case with nearly all cryptocurrencies.monero algorithm bitcoin reserve bitcoin vector bitcoin отзывы сложность monero coindesk bitcoin escrow bitcoin block bitcoin calculator bitcoin и bitcoin bitcoin stealer cryptocurrency capitalisation tether mining bitcoin bloomberg

monero logo bitcoin инвестирование Although radically different from most other payment systems today, these ideas are quite old, dating back to David Chaum, the father of digital cash. In fact, Chaum also made seminal contributions to anonymity networks, and it is in this context that he invented this idea. In his 1981 paper, 'Untraceable Electronic Mail, Return Addresses, and Digital Pseudonyms,'9 he states: 'A digital 'pseudonym' is a public key used to verify signatures made by the anonymous holder of the corresponding private key.'bitcoin home ethereum org bitcoin спекуляция

bitcoin деньги tether пополнить Issuance rate is also impacted by the speed of blocks. There have been a few other events in Ethereum's history which has impacted the issuance rate. Some planned and some not planned.If you are serious about Monero mining, then using a GPU is a better option. Even though it requires a larger investment, it offers a significantly higher hash rate.The bitcoin payment system is purely peer-to-peer, meaning that users are able to send and receive payments to or from anyone on the network around the world without requiring approval from any external source or authority.In the early 20th century, the new and trendy field of 'management science' was greatly influenced by Fordism: the practices of Henry Ford. Fordist mass production was characterized by a rigorous and somewhat dreary focus on efficiency, specialization, mass production, reasonable hours, and living wages. But when the Great Depression came, owners like Ford laid off workers by the tens of thousands. Wages dropped, but the punishing nature of the work remained.Durability is a major issue for fiat currencies in their physical form. A dollar bill, while sturdy, can still be torn, burned, or otherwise rendered unusable. Digital forms of payment are not susceptible to these physical harms in the same way. For this reason, bitcoin is tremendously valuable. It cannot be destroyed in the same way that a dollar bill could be. That's not to say, however, that bitcoin cannot be lost. If a user loses his or her cryptographic key, the bitcoins in the corresponding wallet may be effectively unusable on a permanent basis.12 However, the bitcoin itself will not be destroyed and will continue to exist in records on the blockchain.Main Ethereum termsbitcoin coins dog bitcoin bitcoin ocean blake bitcoin remix ethereum dwarfpool monero casper ethereum mikrotik bitcoin
