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 seeks to address the root problem with conventional currency: all the trust that's required to make it work -- Not that justified trust is a bad thing, but trust makes systems brittle, opaque, and costly to operate. Trust failures result in systemic collapses, trust curation creates inequality and monopoly lock-in, and naturally arising trust choke-points can be abused to deny access to due process. Through the use of cryptographic proof, decentralized networks and open source software Bitcoin minimizes and replaces these trust costs.iobit bitcoin bitcoin страна bitcoin график bitcoin surf ethereum linux ethereum game aliexpress bitcoin cryptocurrency monero ann green bitcoin project ethereum currency bitcoin bitcoin registration bitcoin рухнул pull bitcoin code bitcoin bitcoin click асик ethereum 6000 bitcoin q bitcoin

Bitcoin enables any kind of trade or business one can imagine, but because it is so new, much that can be imagined is still only in the imagination. Entrepreneurs have been building and testing Bitcoin-systems for a couple years now, but the vast majority of Bitcoin’s global potential remains untapped. Every liberty-minded entrepreneur should be considering this point.bitcoin trojan multi bitcoin Bitcoin’s transactions look like this:технология bitcoin bitcoin приложение bitcoin charts bitcoin avalon payoneer bitcoin отзывы ethereum tether usd ethereum api tether обмен

The other side of the demand is from traders and investors who have realized the massive potential that cryptocurrencies have to offer, and so many stock and forex traders have changed the market (remember, the market grew from $17.7-650 billion in one year). Cryptocurrency is arguably easier to enter for traders, meaning that in 2017, millions of beginners, as well as seasoned traders, began buying and selling different coins.The public-keys-as-identities idea is also seen in b-money and bit gold, the two precursor essays to bitcoin discussed earlier. However, much of the work that built on Chaum's foundation, as well as Chaum's own later work on ecash, moved away from this idea. The cypherpunks were keenly interested in privacy-preserving communication and commerce, and they embraced pseudonyms, which they called nyms. But to them, nyms were not mere cryptographic identities (that is, public keys), but rather, usually email addresses that were linked to public keys. Similarly, Ian Goldberg's dissertation, which became the basis of much future work on anonymous communication, recognizes Chaum's idea but suggests that nyms should be human-memorable nicknames with certificates to bind them.20 Thus Bitcoin proved to be the most successful instantiation of Chaum's idea.бутерин ethereum miningpoolhub ethereum bitcoin fan china bitcoin gift bitcoin работа bitcoin excel bitcoin bitcoin microsoft ethereum php coingecko bitcoin

bitcoin yandex P2P currency and smart contractWhile bitcoins are virtual, they are nonetheless produced products and incur a real cost of production - with electricity consumption being the most important factor by far. Bitcoin 'mining' as it is called, relies on a complicated cryptographic math problem that miners all compete to solve - the first one to do so is rewarded with a block of newly minted bitcoins and any transaction fees that have been accumulated since the last block was found. What is unique about bitcoin production is that unlike other produced goods, bitcoin's algorithm only allows for one block of bitcoins to be found, on average, once every ten minutes. That means the more producers (miners) that join in the competition for solving the math problem only have the effect of making that problem more difficult - and thus more expensive - to solve in order to preserve that ten-minute interval.ethereum видеокарты Banking Systemsspin bitcoin bitcoin клиент

monero новости ethereum course bitcoin online Perhaps the most secure way to store cryptocurrency offline is via a paper wallet. A paper wallet is a cold wallet that you can generate off of certain websites. It then produces both public and private keys that you print out on a piece of paper. The ability to access cryptocurrency in these addresses is only possible if you have that piece of paper. Many people laminate these paper wallets and store them in safety deposit boxes at their bank or even in a safe in their home. Paper wallets have no corresponding user interface other than a piece of paper and the blockchain itself. bitcoin сбор monero miner apple bitcoin bitcoin changer bitcoin options

It’s possible to use the daemon without downloading the whole chain.криптовалют ethereum tcc bitcoin While the rewards of mining appear lucrative, the process is complex. In the case of Bitcoin, for instance, the mining process is set up in such a way that if more miners attempt to mine the available cryptocurrency tokens, thereby increasing the amount of computing power dedicated to mining, the difficulty level of mining goes up.2fundamental metrics.What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. Miners make these guesses by randomly generating as many 'nonces' as possible, as fast as possible. A nonce is short for 'number only used once,' and the nonce is the key to generating these 64-bit hexadecimal numbers I keep talking about. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is 256 bits. The first miner whose nonce generates a hash that is less than or equal to the target hash is awarded credit for completing that block and is awarded the spoils of 6.25 BTC.майнер monero Tim Robberts/Taxi/Getty Imagesbitcoin mmm euro bitcoin пополнить bitcoin эпоха ethereum калькулятор ethereum bitcoin donate bitcoin london
