Ethereum has an unusually long list of founders. 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.
Author Laura Shin documents exciting and sometimes tense situations involving the project's founding, the first-ever " DAO " Decentralized Autonomous Organization , and the cryptocurrency craze of 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. In 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.
In January , Ethereum was the second-largest cryptocurrency in terms of market capitalization , behind Bitcoin. After the Constantinople upgrade on 28 February ,  there were two network upgrades made within a month late in the year: Istanbul on 8 December and Muir Glacier on 2 January In March , Visa Inc. 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. Open-source development is currently [ may be outdated as of March ] underway for a major upgrade to Ethereum known as Ethereum 2.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 to up to tens of thousands of transactions per second.
Ethereum 2. Ethereum is a permissionless [ clarification needed ] , 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 of multiple competing chains is to be considered the canonical one. Ether ETH is the cryptocurrency generated by the Ethereum protocol as a reward to miners in a proof-of-work system for adding blocks to the blockchain.
It is the only currency accepted to pay for transaction fees, which also go to miners. The block-addition reward together with the transaction fees provide the incentive to miners to keep the blockchain growing i. Therefore, ETH is fundamental to the operation of the network. Ether is listed on exchanges under the currency code ETH. 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.
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.
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.
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. If at any point the transaction does not have enough gas to perform the next operation, the transaction is reverted but the sender still pays for the gas used. 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. 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.
Blocks are validated approximately every 12 seconds on Ethereum as opposed to approximately every 10 minutes on Bitcoin. Additionally, Bitcoin has a fixed supply of 21,, coins, whereas Ether has no supply cap. The EVM's instruction set is Turing-complete.
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. 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. 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. Like other crypto currencies, Ethereum faces criticism about its environmental impact.

The freedom to accomplish these things without the control or interference of third parties like governments, lawyers, and bankers is the why of getting into cryptocurrency for many people. Because the Ethereum blockchain use cases are so varied, the Ethereum community of developers is the largest among blockchains, and the community of users is among the most active. This article explains how to become a participant in this community, and by extension the entire crypto space, from zero knowledge to full awareness.
However, if you really are new to the space, this article can help you feel comfortable with crypto and save you the considerable hassle of learning from your own mistakes. Use a bookmark and come back to it — like actual books used to work, remember? However, you will also be directed to excellent guides for specific goals on the way, so - onwards! This means that any action on the Ethereum blockchain requires a small fee called gas.
You do not need ETH to receive transfers, though. You are welcome to explore the other blockchains, but you may not need to because the Ethereum environment covers many of things you may have heard about in relation to crypto: - smart contracts - tokens - DeFi - NFTs - yield farming, and much more. Because it allows you to try many different blockchain applications on one platform, setting up just one type of wallet and having an easily accessible, active community of users that you can turn to for answers.
Where can this community be reached? Twitter and Reddit tend to be the platforms where most crypto news and discussion takes place. You can also find MEW on Telegram , another messaging platform popular in the crypto space. You can always receive targeted support in the MEW Reddit community and look for groups that specifically address beginner concerns.
Truly, there are a lot of people out there willing to help Ethereum newbies. Before you can do anything in the crypto market, on any blockchain, you need a wallet. When you enter the Ethereum market, whether you are there to buy, sell, or trade — you need money and some form of ID. In the crypto space, your wallet is both but does NOT necessarily reveal your actual ID beyond the crypto market — more on this later.
For any interaction with the blockchain — sending or receiving money, playing a game, casting a vote or exchanging information — there are no email sign-ups or profile setups, much less logins with Facebook… Your point of entry and connection is always your wallet. Different blockchains will require different blockchain-specific wallets.
We will focus on Ethereum wallets here. Web Web-based wallets may also offer browser extensions, PWAs progressive web apps or be natively integrated in a browser. Desktop Desktop wallets are applications installed on the computer. While some consider these to be safer than web wallets, this is arguable: you still need to be online for transactions to go through, and a PWA from a web wallet can serve much the same purpose as a desktop app namely, prevent you from going to a phishing site by accident.
Besides, desktop apps may not be updated as frequently or reliably as websites and mobile apps, which can set them behind in terms of security features. Hardware Hardware wallets, used in combination with a web interface, are still the highest standard of security in crypto.
They will keep your private keys from being exposed on the internet without the need for an offline computer. Mobile Depending on design and philosophy custodial vs non-custodial , mobile wallet apps can vary in level of security and amount of control over your assets. However, with the world moving to mobile as the default way to use internet services, mobile app security is improving considerably and can have certain advantages over desktop and web wallets.
Paper A method of 'cold storage', which means wallets that are always kept offline. A paper wallet is a private-public key pair, or a mnemonic phrase, printed on a card and kept stored in a safe location, without ever accessing it online. Choice of wallet depends a lot on individual needs and goals, but for your first wallet, try to avoid being impetuous or lazy.
Crypto may not be a chunk of gold yet , but you are putting in your own money into it, so choose the best security for your hard earned coins right from the start. The principle of Do Your Own Research applies here, as it does — very strongly — in the rest of the crypto space. You can read more about different types of Ethereum wallets here , and why using a secure wallet solution is important here.
The procedure for creating a wallet will vary depending on the method and service provider you are going to use, but in all cases you will be required to copy some information and then keep it very safe. Usually, the information — also known as your wallet keys — will consist of two items:. It is NOT recommended to use those directly online — read on to find out why.
The hardware wallet manufacturer will provide specific instructions, but generally you will make a pin or password to access the device and confirm transactions, and write down a word recovery phrase to use if the device breaks, an update goes wrong, or you lose it. The recovery phrase will always lead back to the same addresses, as long as you use the same HD derivation path What path, now? It's one of the options available with hardware wallets. Read about paths here.
Just take note of which path you are using at the very beginning. In an emergency, you want to have all the information about how you created the wallet. Once you have the hardware wallet set up, you will need to use it in combination with a web interface like MEW. Some devices have native application interfaces, but they usually offer fewer functions.
When blockchains and cryptocurrencies were first introduced, there were no hardware wallets or wallet interface apps to help people interact with the blockchain. It was accessible only to developers familiar with the command line, and wallet generation was not adapted for regular users and good security practices. At that point, most users created wallets via private key or encrypted keystore file, and more rarely via mnemonic phrase.
These software wallet creation methods are still available, but using them online means greatly increasing the chances of being phished. In fact, some wallet interfaces and services are planning to discontinue access via these methods altogether. If you need more convincing, read this. You can read about the offline procedure as used in MEW here. The general purpose of offline access is to keep your private keys from being exposed on the internet. Hardware wallets or a good mobile wallet will do this for you without the complex setup.
Increasingly, as more applications are built on Ethereum, web browsers and browser extensions are providing integrated wallet and Web3 services. What does this mean? By downloading a specific browser like Opera or Brave or installing a browser extension like MetaMask , you will be continuously connected to your wallet while using the browser so you can interact with decentralized applications seamlessly. It's important to keep in mind that with browser wallets, you still need to keep track of your keys and store them in a safe location.
Browser wallets are a better choice than direct software access, but hardware wallets are still the most secure solution for holding large amounts of currency for long periods. Browser wallets are more suitable for holding small amounts for the purpose of daily interaction with applications.
MEW's mobile app, MEW wallet , is a truly non-custodial solution — you remain in full control of your keys and assets. You can use the app both as a standalone wallet and by connecting to the MEW web interface via a QR code. Most of the time, a non-custodial wallet will give you your private key or seed phrase and will not require KYC. A custodial wallet, like Coinbase, will let you create a password only, will not give you the private key or seed phrase, and will require you to submit identification for KYC.
Before using a mobile wallet app, figure out what kind of custodianship is involved, and make your decision according to the setup which works best for your needs. It seems that a fair number of crypto beginners have heard of paper wallets as a safe method for cold storage, as well as a good way to gift crypto to someone.
What makes it safe is that after creation, the wallet is never accessed online. The public address can be used to deposit more assets to the wallet and to view the wallet balance on a blockchain explorer. However, using that private key or seed phrase even once to access the wallet online and send a transaction will null its cold storage status and leave it vulnerable to being phished. Once you have an Ethereum address, you can start receiving ETH and tokens. Copy your public address only it starts with 0x and has 40 more alpha-numeric characters, like this: 0x29cAbc05c5Fca8d8cDd56bceFda and give to people so they can send you crypto.
There is no harm in receiving free token airdrops, although most of them are obscure and will not have any real market value for a long time, if ever. No one ever gives away valuable currency. For anything besides receiving assets, you will need some ETH in your wallet to pay for gas. Gas prices can vary Eth Gas Station will have the current rates , and some operations like swapping will require more gas than simply sending ETH, but most wallets will calculate gas for your transaction automatically.
One way to get ETH is to buy it with a credit card through an exchange. Take note that when you do this, you will have to go through the KYC Know Your Customer procedure which will essentially connect your Ethereum wallet to your real identity. But it does mean that your government and bank can know your cryptocurrency history, if they choose to take interest and investigate.
More on this later…. There is an alternative way of getting ETH: receiving it from another user a friend, a client, an employer paying for services, or even a stranger on Reddit who sends you a few bucks to pay for gas and help you move your assets. For now, these are not widely available, and their reliability is not well-established. Of course, ETH can also be mined, but that requires sophisticated blockchain knowledge and equipment. Frequently, people come into crypto after being inspired by a particular project and deciding to invest in it.
Good news! Most of the time, the tokens of such projects are in the ERC20 format, based on Ethereum. Sometimes projects distribute tokens for free airdrop them , in which case all you need to do is provide your public address. If the tokens have market value, you can use an exchange to swap ETH for the token of your choice. If you are using a custodial exchange wallet like Coinbase, your assets are already on the exchange, so you just have to check which tokens are supported.
MEW is a non-custodial wallet, but it is partnered with decentralized exchanges that provide swaps within the MEW interface. When you use non-custodial wallets that do not integrate any exchanges, or you need to swap a token not supported by the integrated exchanges, you will have to move your assets to a wallet on the exchange first, conduct the swap there, and then move the swapped coins back to your non-custodial wallet.
Swaps are not limited to ETH and tokens. Regardless of which wallet interface you are using, if you are ever in doubt about your balance or unsure about the status of a transaction, there is one source of blockchain truth you can always turn to — the blockchain explorer. Wallet interfaces may have errors that prevent seeing correct balances, or they may fail to show the most recent transaction details.
The block explorer will always have that information up to date. At the moment, the most popular explorer for Ethereum is Etherscan. If you put your public address in the search field, you can view your ETH and token balances, as well as the full transaction history. You can also explore token prices, average gas fees, latest block information, transaction volume, miner rewards, and lots of other data.
Learning to use the block explorer is very helpful for navigating the crypto space with confidence. So when you use your online wallet, only keep what you need to buy and sell on this type of wallet. You can then move the majority of your Ether investment to an offline or hardware wallet for safe keeping.
Popular wallets for ways to store Ethers offline include Exodus , or the hardware wallet Ledger Nano S. You can read our full guide on how to store cryptocurrency and what type of online, offline or hardware wallets would work best for your needs. After setting up your wallet, the next step in buying Ethereum is to register for an exchange. While there are many international exchange platforms on the market, depending on which country you are in, there may be a preferred exchange for purchasing your cryptocurrency of choice.
Be sure to look into this as this may be more compatible for your needs. Otherwise, there are a few options with how to buy Ethereum:. This option usually includes you purchasing Ether from a seller directly and without a middleman such as an exchange. Here, the seller will sell Ethers at an exchange rate set by him or herself and you would have to agree or disagree on the price. From there they will transfer the designated Ethers to your wallet directly. Usually, people who opt for this know someone who they can purchase from.
In some cases, there may be countries with certain regulations on the buying and selling of cryptocurrency, making direct trading the most viable option. For those learning how to buy Ethereum but not wanting to jump head first into a full marketplace, cryptocurrency brokers provide an easy medium to get started. Unlike a trading platform where buyers and sellers list their bids, cryptocurrency brokers list one set exchange rate based on what the buyers and sellers agree to.
With it being a more straightforward option, many people learning how to buy Ethereum may choose this route and register for popular brokers like eToro to start. Trading platforms like eToro and Coinbase are generally seen as the marketplace for buying, selling, and making money with cryptocurrency : This is where buyers and sellers can make bids on their desired trading price, either a specific price or a range of prices depending on the market value of cryptocurrencies like Ether.
Here, you may have to wait a few seconds to several minutes for someone to match your bid price to make the sale. By using trading platforms, you also can get a sense of how much people are willing to pay for cryptocurrencies like Ether from a play-by-play perspective. For both brokers and trading platforms, you can purchase Ether through trading other cryptocurrencies like Bitcoin, Litecoin or Ripple.
You can also attach a debit or credit card, bank account or maybe even a PayPal account so you can purchase Ether directly from a fiat currency. Get a cheat code to making money trading. Copy pro-traders with the click of a button. One thing to note about learning how to buy Ethereum are the transaction fees involved: Usually with a trading platform, the fee is listed in cryptocurrency. Make sure to compare the cryptocurrency value to a fiat currency value to make sure you agree to the fee.
This is an extreme example. But, it is important to always check the value of the trading platform transactions fees before proceeding. There are a few safety tips and tricks to keep in mind while learning how to buy Ethereum. When you first set up your accounts, add any security options available to you so you can keep your account safe. This includes regularly changing your password. While this may sound like overkill, these are steps you can take to ensure the safety of your investments!
Many online wallets, offline wallets, hardware wallets and exchange accounts will also have a 2-factor authentication option. Enable this as an extra layer of security at login so anyone who may try to access your account will still need authentication from your mobile or other computer to confirm a login request. In addition to adding security measures when possible, make sure to backup all wallets and enable recovery options for offline or hardware wallets.
While all wallets and exchanges aim for the best security possible, there is little you can do if your computer or hardware wallet is affected by malware, damaged, stolen or lost. By making backups of your wallet and enabling recovery options, you can regain access.
Even though scenarios like these sound a little far fetched and maybe even near impossible, do what it takes to keep your Ether investments safe. Most trading platforms and brokers will let you register for an account for free. This is done for a few reasons: The first is for safety of each account. The second is so that the exchange can confirm that each user is a verifiable person and not a bot or someone creating fake accounts. Most exchanges will require 2 things to confirm your identity: a copy of a current ID and a current photo.
They may have specifications like having the name of the exchange written on a piece of paper next to you. In any case, after you submit both for review and the application is approved, you will have full access to the exchange platform. You can then add a payment option and learn how to buy Ethereum through experience! Ether is the second largest cryptocurrency traded on the market today.
