He stated, "I immediately realized that I liked it better than all of the other alternatives that I had seen; I suppose it was the fact that [it] sounded nice and it had the word ' ether ', referring to the hypothetical invisible medium that permeates the universe and allows light to travel.

Formal development of the software underlying Ethereum began in early through a Swiss company, Ethereum Switzerland GmbH EthSuisse. This work was done by Gavin Wood, then the chief technology officer , in the Ethereum Yellow Paper that specified the Ethereum Virtual Machine. Development was funded by an online public crowd sale from July to August , in which participants bought the Ethereum value token Ether with another digital currency, Bitcoin.

While there was early praise for the technical innovations of Ethereum, questions were also raised about its security and scalability. Several codenamed prototypes of Ethereum were developed over 18 months in and by the Ethereum Foundation as part of their proof-of-concept series.

The Olympic network gave users a bug bounty of 25, Ether for stress-testing the Ethereum blockchain. On 30 July , "Frontier" marked the official launch of the Ethereum platform, and Ethereum created its "genesis block.

After the hard fork, Ethereum subsequently forked twice in the fourth quarter of to deal with other attacks. In March , various blockchain startups, research groups, and Fortune companies announced the creation of the Enterprise Ethereum Alliance EEA with 30 founding members.

Morgan , Cooley LLP , Merck KGaA , DTCC , Deloitte , Accenture , Banco Santander , BNY Mellon , ING , and National Bank of Canada. In January , Ethereum was the second-largest cryptocurrency in terms of market capitalization , behind Bitcoin. After the Constantinople upgrade on 28 February , [26] there were two network upgrades made within a month late in the year: Istanbul on 8 December and Muir Glacier on 2 January In , Ethereum Foundation employee Virgil Griffith was arrested by the US government for presenting at a blockchain conference in North Korea.

In March , Visa Inc. announced that it began settling stablecoin transactions using Ethereum. There were two network upgrades in The first was "Berlin", implemented on 14 April The mechanism causes a portion of the Ether paid in transaction fees for each block to be destroyed rather than given to the miner, reducing the inflation rate of Ether and potentially resulting in periods of deflation.

On 27 August , the blockchain experienced a brief fork that was the result of clients running different incompatible software versions. In August , three Israeli researchers Aviv Yaish , Gilad Stern and Aviv Zohar disclosed that they found the first instance of an in-the-wild attack on a major cryptocurrency, specifically on Ethereum.

The attack, which they call "Uncle Maker", was executed by the F2Pool mining pool starting in October and lasting at least until August This attack enabled F2Pool to game Ethereum's proof of work mechanism in a manner that ensures F2Pool's blocks win in case they are tied with blocks mined by other pools.

Open-source development is currently underway for a multi-year major upgrade to Ethereum known as Ethereum 2. The main purpose of the upgrade is to increase transaction throughput for the network from the current rate of about 15 transactions per second [ citation needed ] to, theoretically, up to tens of thousands of transactions per second. Ethereum is a permissionless, [a] non-hierarchical network of computers nodes that build and come to a consensus on an ever-growing series of "blocks", or batches of transactions, known as the blockchain.

Each block contains an identifier of the chain that must precede it if the block is to be considered valid. Whenever a node adds a block to its chain, it executes the transactions in the block in the order they are listed, thereby altering the ETH balances and other storage values of Ethereum accounts. These balances and values, collectively known as the "state", are maintained on the node separately from the blockchain , in a Merkle tree.

Each node communicates with a relatively small subset of the network—its "peers". Whenever a node wishes to include a new transaction in the blockchain, it sends a copy of the transaction to each of its peers, who then send a copy to each of their peers, and so on. In this way, it propagates throughout the network.

Certain nodes, called miners, maintain a list of all of these new transactions and use them to create new blocks, which they then send to the rest of the network. Whenever a node receives a block, it checks the validity of the block and of all of the transactions therein and, if it finds the block to be valid, adds it to its blockchain and executes all of those transactions. Since block creation and broadcasting are permissionless, a node may receive multiple blocks competing to be the successor to a particular block.

The node keeps track of all of the valid chains that result from this and regularly drops the shortest one: According to the Ethereum protocol, the longest chain at any given time is to be considered the canonical one. Ether ETH is the cryptocurrency generated in accordance with the Ethereum protocol as a reward to miners in a proof-of-work system for adding blocks to the blockchain. This is known as the block reward.

Additionally, Ether is the only currency accepted by the protocol as payment for a transaction fee, which also goes to the miner. The block reward together with the transaction fees provide the incentive to miners to keep the blockchain growing i. to keep processing new transactions. Therefore, ETH is fundamental to the operation of the network. Ether may be "sent" from one account to another via a transaction, which simply entails subtracting the amount to be sent from the sender's balance and adding the same amount to the recipient's balance.

Ether is often erroneously referred to as "Ethereum". Ether is listed on exchanges under the abbreviation ETH. The Greek uppercase Xi character Ξ is sometimes used for its currency symbol. The shift to Ethereum 2. There are two types of accounts on Ethereum: user accounts also known as externally-owned accounts and contracts. Both types have an ETH balance, may send ETH to any account, may call any public function of a contract or create a new contract, and are identified on the blockchain and in the state by an account address.

User accounts are the only type of account that may create transactions. For a transaction to be valid, it must be signed using the sending account's private key, the character hexadecimal string from which the account's address is derived. The algorithm used to produce the signature is ECDSA.

Importantly, this algorithm allows one to derive the signer's address from the signature without knowing the private key. Contracts are the only type of account that has associated code a set of functions and variable declarations and contract storage the values of the variables at any given time.

A contract function may take arguments and may have return values. In addition to control flow statements, the body of a function may include instructions to send ETH, read from and write to the contract's storage, create temporary storage memory that vanishes at the end of the function, perform arithmetic and hashing operations, call the contract's own functions, call public functions of other contracts, create new contracts, and query information about the current transaction or the blockchain.

Ethereum addresses are composed of the prefix " 0x " a common identifier for hexadecimal concatenated with the rightmost 20 bytes of the Keccak hash of the ECDSA public key the curve used is the so-called secpk1. In hexadecimal, two digits represent a byte, and so addresses contain 40 hexadecimal digits, e. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce.

The Ethereum Virtual Machine EVM is the runtime environment for transaction execution in Ethereum. It includes a stack , memory, gas balance see below , program counter , and the persistent storage for all accounts including contract code.

When a transaction calls a contract's function, the arguments in the call are added to the stack and the EVM translates the contract's bytecode into stack operations.

The EVM is isolated from the other files and processes on the node's computer to ensure that for a given pre-transaction state and transaction, every node produces the same post-transaction state, thereby enabling network consensus. The formal definition of the EVM is specified in the Ethereum Yellow Paper.

Gas is a unit of account within the EVM used in the calculation of a transaction fee, which is the amount of ETH a transaction's sender must pay to the miner who includes the transaction in the blockchain. Each type of operation which may be performed by the EVM is hardcoded with a certain gas cost, which is intended to be roughly proportional to the amount of resources computation and storage a node must expend to perform that operation.

When a sender creates a transaction, the sender must specify a gas limit and gas price. The gas limit is the maximum amount of gas the sender is willing to use in the transaction, and the gas price is the amount of ETH the sender wishes to pay to the miner per unit of gas used.

The higher the gas price , the more incentive a miner has to include the transaction in their block, and thus the quicker the transaction will be included in the blockchain. The sender buys the full amount of gas i. their ETH balance is debited the amount: gas limit × gas price up-front, at the start of the execution of the transaction, and is refunded at the end for any unused gas. If at any point the transaction does not have enough gas to perform the next operation, the transaction is reverted but the sender is only refunded for the unused gas.

This fee mechanism is designed to mitigate transaction spam, prevent infinite loops during contract execution, and provide for a market-based allocation of network resources.

Our governance is inherently social, people who are more connected in the community have more power, a kind of soft power.

Vlad Zamfir, Ethereum core developer, The New Yorker [18]. In October , [69] a development governance was proposed as the Ethereum Improvement Proposal EIP , standardized on EIP The difficulty bomb is an Ethereum protocol feature that causes the difficulty of mining a block to increase exponentially over time after a certain block is reached, with the intended purpose being to incentivize upgrades to the protocol and prevent miners from having too much control over upgrades.

As the protocol is upgraded, the difficulty bomb is typically pushed further out in time. The protocol has included a difficulty bomb from the beginning, and the bomb has been pushed back several times. Bitcoin's primary use case is as a store of value and a digital currency. Ether can also be used as a digital currency and store of value, but the Ethereum network also makes it possible to create and run decentralized applications and smart contracts.

Although both Bitcoin and Ethereum can be mined through proof-of-work, in Ethereum blocks are validated approximately every 12 seconds as opposed to approximately every 10 minutes on Bitcoin, as Ethereum relies on a slightly different mechanism called "Modified GHOST", which is based on a protocol created by Yonatan Sompolinsky and Aviv Zohar.

Additionally, Bitcoin has a fixed supply of 21,, coins, whereas Ether has no supply cap. The EVM's instruction set is Turing-complete. initial coin offerings , decentralized finance , decentralized exchanges , decentralized autonomous organizations DAOs , games, prediction markets , and gambling.

Ethereum's smart contracts are written in high-level programming languages and then compiled down to EVM bytecode and deployed to the Ethereum blockchain. They can be written in Solidity a language library with similarities to C and JavaScript , Serpent similar to Python , but deprecated , Yul an intermediate language that can compile to various different backends — EVM 1.

There was also [ when? One issue related to using smart contracts on a public blockchain is that bugs, including security holes, are visible to all but cannot be fixed quickly.

There is ongoing research on how to use formal verification to express and prove non-trivial properties. A Microsoft Research report noted that writing solid smart contracts can be extremely difficult in practice, using The DAO hack to illustrate this problem. The report discussed tools that Microsoft had developed for verifying contracts, and noted that a large-scale analysis of published contracts is likely to uncover widespread vulnerabilities.

The report also stated that it is possible to verify the equivalence of a Solidity program and the EVM code. The ERC Ethereum Request-for-Comments 20 Token Standard allows for fungible tokens on the Ethereum blockchain. The standard, proposed by Fabian Vogelsteller in November , implements an API for tokens within smart contracts.

Smart contracts that correctly implement ERC processes are called ERC Token Contracts, and they keep track of created tokens on Ethereum. Ethereum also allows for the creation of unique and indivisible tokens, called non-fungible tokens NFTs. Decentralized finance DeFi is a use case of Ethereum. Examples of DeFi platforms include MakerDAO and Compound. Ethereum-based software and networks, independent from the public Ethereum chain , are being tested by enterprise software companies.

Ethereum-based permissioned blockchain variants are used and being investigated for various projects:. In Ethereum, all smart contracts are stored publicly on every node of the blockchain, which has costs. Being a blockchain means it is secure by design ; it is an example of a distributed computing system with high Byzantine fault tolerance.

Every new transaction is recorded on a new block, which is connected to previous and future blocks in a chain. The downside is that performance issues arise because every node calculates all the smart contracts in real-time.

As of January [update] , the Ethereum protocol could process about 25 transactions per second. In comparison, the Visa payment platform processes 45, payments per second. This has led some to question the scalability of Ethereum.

Ethereum engineers have been working on sharding the calculations, and the next step Ethereum 2 was presented at Ethereum's Devcon 3 in November Ethereum's blockchain uses Merkle trees for security reasons, to improve scalability, and to optimize transaction hashing.

The network has faced congestion problems, such as in in relation to Cryptokitties. In August the Digital Commodities Consumer Protection Act announced that the government would be treating Ethereum and other cryptocurrencies as commodities and be regulated by the Commodity Futures Trading Commission CFTC.

Like other cryptocurrencies, Ethereum has been heavily criticised for its environmental impact. household uses in a workweek.

doi : No one can predict the price of Ethereum ETH , but the token has climbed steeply in the past, thanks to the enduring popularity of DApps and NFTs. A part of every transaction fee the base fee is burned and removed out of circulation. This blockchain is validated by a network of automated programs that reach a consensus on the validity of transaction information. By default, Ethereum uses the Proof-of-Work PoW consensus mechanism, but the network is slowly migrating to a Proof-of-Stake PoS as part of its Ethereum 2.
