Introduction
Ethereum builds on blockchain and cryptocurrency concepts, so if you are not familiar with these, it’s worth reading a gentle introduction to bitcoin and a gentle introduction to blockchain technology first. This article assumes the reader has a basic familiarity with how Bitcoin works.
What is Ethereum?
Ethereum is software running on a network of computers that ensures that data and small computer programs called smart contracts are replicated and processed on all the computers on the network, without a central coordinator. The vision is to create an unstoppable censorship-resistant self-sustaining decentralised world computer. The official website is https://www.ethereum.org
It extends the blockchain concepts from Bitcoin which validates, stores, and replicates transaction data on many computers around the world (hence the term ‘distributed ledger’). Ethereum takes this one step further, and also runs computer code equivalently on many computers around the world.
What Bitcoin does for distributed data storage, Ethereum does for distributed data storage plus computations. The small computer programs being run are called smart contracts, and the contracts are run by participants on their machines using a sort of operating system called a “Ethereum Virtual Machine”.
How do you run Ethereum?
You can download (or write yourself if you have the patience) some software called an Ethereum client. Just like BitTorrent or Bitcoin, the Ethereum client will connect over the internet to other people’s computers running similar client software and start downloading the Ethereum blockchain from them to catch up. It will also independently validate that each block conforms to the Ethereum rules.
What does the Ethereum client software do? You can use it to:
Connect to the Ethereum network
Explore Ethereum’s blockchain
Create new transactions and smart contracts
Run smart contracts
Mine for new blocks
Your computer becomes a ‘node’ on the network, running an Ethereum Virtual Machine, and behaves equivalently to all the other nodes. Remember in a peer-to-peer network there is no ‘master’ server and any computer has equivalent powers or status to any other.

Smart contracts play a huge role when it comes to how to create a cryptocurrency. For those who don’t know what a smart contract is, let me briefly explain:IRC FreeNode network channels #litecoin (for general users) and #litecoin-dev (for developers).конвертер ethereum equihash bitcoin bitcoin xt bitcoin луна galaxy bitcoin shot bitcoin bitcoin сервисы ethereum buy bitcoin collector

habr bitcoin ethereum casino dwarfpool monero видеокарты bitcoin Hash rate is the number of calculations that your hardware can perform every second as it tries to crack the mathematical problem we described in our mining section. Hash rates are measured in megahashes, gigahashes, and terahashes per second (MH/sec, GH/sec, and TH/sec). The higher your hash rate (compared to the current average hash rate), the more likely you are to solve a transaction block. The bitcoin wiki’s mining hardware comparison page is a good place to go for rough information on hash rates for different hardware.deep bitcoin In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producing orphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.However, given a limited amount of transactions that can be stored in a block, making the block time too long would decrease the number of transactions the network can process per second, negatively affecting network scalability.bitcoin комиссия количество bitcoin india bitcoin ethereum russia bitcointalk monero If you’ve made it this far, then congratulations! There is still so much more to explain about the system, but at least now you have an idea of the broad outline of the genius of the programming and the concept. For the first time we have a system that allows for convenient digital transfers in a decentralized, trust-free and tamper-proof way. To understand the concept of 'what is a smart contract?' consider the purchase of a chocolate bar from a vending machine. The buyer deposits change then presses the button corresponding to the selection. That button, mapped against that particular slot, activates a lever in the machine to push out the candy. The transaction occurred without the need for a cashier or clerk. A smart contract is similar to a vending machine in that it eliminates the need for an intermediary. In this case, the vending machine is replacing a direct seller and allowing the consumer to make a purchase without a middleman.bitcoin youtube water bitcoin dapps ethereum ethereum цена bitcoin virus дешевеет bitcoin forbot bitcoin monero client bitcoin xyz трейдинг bitcoin qr bitcoin bitcoin index bitcoin js bitcoin даром bitcoin расчет coinder bitcoin bitcoin cudaminer mercado bitcoin net bitcoin бутерин ethereum
