What is Ethereum?
World computer, truth machine – with the second-largest cryptocurrency
fundamentals-ethereum
Since its birth in 2015, Ethereum has been focused on one core principle: decentralization.
This vision holds that a new kind of internet can make it possible to transfer value independent of 3rd-parties and eliminate the weaknesses and security risks of centralized data storage and applications.
Ethereum’s native cryptocurrency, Ether (ETH), which helps power the Ethereum blockchain and keep it secure, has risen in value to become the second-largest cryptocurrency by market capitalization.
To understand the power of Ethereum and the promise of decentralization that it seeks to attain, it helps to take a closer look at what it is and how its innovations, including smart contracts, can potentially change many aspects of the world we live in.
The Beginnings of Ethereum
After the birth of Bitcoin, developers in the crypto space made many attempts to extend the possibilities of the Bitcoin blockchain for other use cases beyond peer-to-peer payments and finance.
One such developer was Vitalik Buterin. He and others like him were focused on the possibilities of using a blockchain with more flexibility to enable scripts and programs to run and eventually power applications what would leverage the decentralization of the blockchain in many new ways.
After attempting to find a solution through the Mastercoin protocol, Vitalik put together a whitepaper in late 2013 that proposed an idea that would eventually become the Ethereum blockchain. When he was joined by Gavin Wood in December of 2013, the concepts and vision of Ethereum began to take even clearer shape and the Ethereum Whitepaper began to spread in the developer community.
In the following months, the community grew quickly and attracted numerous others including Joe Lubin, Mihai Alisie, Charles Hoskinson and more. The core group of developers and proponents ended up coming to Zug, Switzerland to set up a foundation in support of the vision that they had laid out.
In July 2014, the Ethereum Foundation conducted a crowdsale in which it sold over 50 million ETH to the public. The following year, on 30 July 2015, the genesis block of the Ethereum blockchain was mined and the Ethereum journey towards decentralization began in earnest.
Ethereum as the World Computer
What began in 2015 was more than the launch of another cryptocurrency with its own blockchain. The vision was to create a world computer.
What does this mean?
Think for a moment about what a blockchain was originally designed to do – store a distributed record of transactions of a peer-to-peer electronic cash (Bitcoin). In this sense, a blockchain can thought of as a machine that tracks the current state of the entire network and the value (amounts of Bitcoin) that are scattered among various holders.
When Bob sends a certain amount of Bitcoin to Alice, the Bitcoin blockchain records this transaction – in other words it updates the current state of the ledger and takes note that Bob now has less Bitcoin and Alice has more.
Similarly, Ethereum records the transactions of ETH. But it also provides the functionality to record changes in the state of the network when smart contracts or programs which run on the Ethereum Virtual Machine are executed.
This might not seem like a difficult or revolutionary thing, until we think about the implications. Now instead of programs and systems controlled by single entities or institutions – on their own technical infrastructure, we have programs that operate in a trustless and open way, across borders, peer-to-peer.
This enables decentralized applications (dApps) which do not live just on one computer or server, to operate even if they may have various inputs and changes in state over time. The consensus mechanism of the blockchain helps maintain their integrity even without intermediaries or counter-parties.
Now with all of this, we get a system which can execute programs over and over again, anywhere in the world, with guaranteed code execution because the logic is embedded on the blockchain.
In other words, we get a world computer.
Ethereum as a smart contract platform
The programs – or more accurately scripts – which run on the Ethereum blockchain are commonly referred to as smart contracts.
Let’s take a look at an example—a decentralized application for flight delay insurance. The heart of the application is a smart contract – a program running on the Ethereum blockchain – which can:
Accept premiums (in ETH) from passengers wishing to buy flight delay insurance for their journey
Calculate the risk and premium level for individual flights based on historical data and current weather information (provided by so-called oracles)
Determine if the flight had been delayed based on a link to flight tracking database
Automatically distribute the correct insurance payout to passengers who were on a delayed flight.
Obviously, such insurance is available today from various providers around the world, but using the Ethereum blockchain allowed the flight delay insurance application to automate the entire process from the insurance policy setup to the moment of payout, and made it possible for people in different places to interact with the system without cumbersome paperwork or one centralized authority and ultimately provide a much better customer experience.
This is just one example of a smart contract in action. Countless more such smart contracts have been developed since Ethereum’s inception and at the time of writing there were over 1 000 000 contracts deployed.
Ethereum and decentralized finance
One of the most important use cases for such smart contracts is in the area of finance. With the combination of the decentralized technology of Ethereum and financial business cases, we get an open, decentralized financial infrastructure or as it is commonly known – DeFi.
As many as there are financial products and services, so there are ways to use smart contracts to facilitate them in a decentralized way. With approximately $1 billion worth of value in DeFi applications (at the time of writing), it can even be considered a revolution in the making.
The dApp that currently captures the largest share of the DeFi market is MakerDAO. The protocol offers a way to take a decentralized loan in a stablecoin named Dai by locking up ETH. Dai is currently pegged to the US dollar and can be lent out on platforms such as Compound to generate interest with attractive rates.
Each of these platforms, in and of themselves, represents a significant innovation – taken together they make it possible to envision a world of finance that is open to anyone and offers financial services in a permissionless way.
bitcoin galaxy доходность bitcoin Mining cryptocurrency at a rate worthwhile to the miners requires ungodly processing power, courtesy of specialized hardware. To mine most cryptocurrencies, the central processing unit in your Dell Inspiron isn’t anywhere near fast enough to complete the task. Which brings us to another point of differentiation for litecoins; they can be mined with ordinary off-the-shelf computers more so than other cryptocurrencies can. Although the greater a machine’s capacity for mining, the better the chance it’ll earn something of value for a miner.It is scarce, durable, portable, divisible, verifiable, storable, relatively fungible, salable, and recognized across borders, and therefore has the properties of money.генераторы bitcoin 'Metcalfe's Law can also be applicable.'monero rub ethereum заработок презентация bitcoin bitcoin fpga bitcoin landing Compare Crypto Exchanges Side by Side With Othersbitcoin funding bitcoin explorer bitcoin компьютер программа tether брокеры bitcoin ютуб bitcoin bitcoin step cryptocurrency tech logo ethereum ethereum crane биткоин bitcoin

Download an app, link a bank account, buy bitcoin. Get a piece of hardware, hardware generates address, send money to address. No one can take it from you and no one can print more. In that moment, bitcoin becomes far more intuitive. Seems complicated from the periphery, but it is that easy, and anyone with common sense and something to lose will figure it out; the benefit is so great and money is such a basic necessity that the bar on a relative basis only gets lower and lower in time. Self-preservation is the only motivation necessary; it ultimately breaks down any barriers that otherwise exist.magic bitcoin падение ethereum We have a public distributed ledger, which works using a hashing encryption.birds bitcoin etoro bitcoin оплатить bitcoin ethereum contracts bitcoin plus config bitcoin wallet tether майнеры bitcoin demo bitcoin ethereum charts

The primary use case for USDT is moving money between exchanges quickly to take advantage of arbitrage opportunities when the price of cryptocurrencies differs on two exchanges; traders can make money on this discrepancy. But it has found other applications: Chinese importers stationed in Russia have also used USDT to send millions of dollars worth of value across the border, bypassing strict capital controls in China.monero купить bitcoin china bitcoin криптовалюта ethereum виталий cubits bitcoin ethereum обменять forex bitcoin bitcoin видеокарты биржа ethereum бонусы bitcoin neo cryptocurrency боты bitcoin rus bitcoin bitcoin комбайн bitcoin 100 second bitcoin 1080 ethereum обмен tether vpn bitcoin

At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.ethereum скачать bitcoin miner фото ethereum
