WHAT IS ETHEREUM

Decentralized and open-source, Ethereum is a blockchain that supports smart contracts. The platform’s native cryptocurrencies is ether, abbreviated as ETH and represented by the [a] sign. Ether’s market valuation is second only to that of bitcoin among cryptocurrencies.2013 saw the creation of Ethereum by programmer Vitalik Buterin.

Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin were additional Ethereum founders. Crowdfunding for the network’s development work began in 2014, and on July 30, 2015, the network launched. Anyone can upload permanent, irreversible, decentralized programs to Ethereum, allowing users to communicate with them.
Without the use of conventional financial intermediaries like brokerages, exchanges, or banks, decentralized finance (DeFi) applications offer a wide range of financial services, such as enabling cryptocurrency owners to borrow money against their holdings or lend them out for interest. Users of Ethereum can also create and exchange NFTs, which are distinctive tokens that indicate ownership of a related asset or privilege and are accepted by a variety of institutions. On top of the Ethereum blockchain, numerous other cryptocurrencies use the ERC-20 token standard, and they have made use of the Ethereum platform for ICOs.

In an upgrading procedure known as “the Merge,” Ethereum switched from proof-of-work (PoW) to proof-of-stake (PoS) on September 15, 2022.
As a result, Ethereum’s energy consumption rate dropped by around 99.95%, saving an estimated 110 TWh of energy annually (110 billion kilowatt-hours). Users of Ethereum don’t need to do anything to activate the upgrade. During the Merge, the Beacon Chain, a proof-of-stake blockchain network protected by validators staking ether, took the place of Ethereum’s proof-of-work mining system.
Programmer and co-founder of Bitcoin Magazine Vitalik Buterin first introduced Ethereum in a late 2013 white paper that outlined a method for creating decentralized applications.
Buterin argued to the Bitcoin Core developers that blockchain technology and Bitcoin might be used for purposes other than just monetary exchange and that a more robust language was required for application development.
that might result in real-world assets like stocks and real estate being linked to the blockchain. [19] Buterin produced the Colored Coins project’s white paper explaining potential use cases for blockchain technology in 2013 while working briefly with eToro CEO Yoni Assia on it. [20] He advocated the creation of a new platform with a more sophisticated scripting language—a Turing-complete programming language—that would later become Ethereum, but after failing to secure agreement on how the project should move forward.
In January 2014, Ethereum was introduced during the North American Bitcoin Conference in Miami. Gavin Wood, Charles Hoskinson, and Anthony Di Iorio, the project’s financier, rented a home in Miami alongside Buterin during the conference so they could have a better understanding of what Ethereum might develop into.
Di Iorio asked his buddy Joseph Lubin, who then asked journalist Morgen Peck, to testify. [22] Peck later wrote in Wired about the encounter. [23] The founders reconvened in Zug, Switzerland, six months later, where Buterin informed them that the project would move forward as a non-profit. At that point, Hoskinson quit the project and soon after started IOHK, a blockchain business that created Cardano.

Ether

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. Ether is represented in the state as an unsigned integer associated with each account, this being the account’s ETH balance denominated in wei (1018 wei = 1 ether).Each block, new ETH is generated by the addition of a protocol-specified amount, currently 2 × 1018 wei (equal to 2 ETH), to the balance of any account of the miner’s choosing. 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.e. 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.
The founders of Ethereum make up an extremely extensive list.

Writing as Anthony Di Iorio: “In December 2013, Vitalik Buterin, myself, Charles Hoskinson, Mihai Alisie, and Amir Chetrit (the original five) created Ethereum. Early in 2014, founders Joseph Lubin, Gavin Wood, and Jeffrey Wilcke were added.” Buterin looked through a list of science fiction components on Wikipedia before settling on the name Ethereum.

“I quickly recognized that I liked it better than any of the other choices that I had seen,” he remarked, “I believe it was the fact that [it] sounded pleasant and it featured the word ‘ether,’ referring to the supposed invisible medium that permeates the world and permits light to travel.” Buterin aimed for his platform to serve as the invisible foundation for any applications built upon it.

Development (2014)

Early in 2014, a Swiss firm called Ethereum Switzerland GmbH formally started developing the software that underpins Ethereum (EthSuisse).
Before it could be implemented in software, the concept of storing executable smart contracts in the blockchain needed to be defined.
Gavin Wood, who was the chief technical officer at the time, completed this work for the Ethereum Yellow Paper, which described the Ethereum Virtual Machine. A non-profit Swiss foundation called the Ethereum Foundation (Stiftung Ethereum) was subsequently established. From July to August 2014, a public online crowd sale was held to raise money for development. Participants purchased the Ethereum value token (ether) with bitcoin, another type of digital currency. While Ethereum’s technical advances were first praised, concerns regarding its security and scalability were also voiced.
In the final month of the year, two network upgrades were made after the Constantinople upgrade on February 28, 2019. Istanbul on December 8, 2019, and Muir Glacier on January 2, 2020.
Virgil Griffith, an employee of the Ethereum Foundation, was detained by the US government in 2019 after giving a speech at a blockchain conference in North Korea. In 2021, he would ultimately enter a guilty plea to the charges[clarification required].
Visa Inc. declared in March 2021 that it had started using Ethereum to settle stablecoin transactions. JP Morgan Chase, UBS, and MasterCard stated in April 2021 that they were investing US$65 million in ConsenSys, a software development company that creates infrastructure connected to Ethereum.
In 2021, there were two network upgrades. The first was “Berlin,” which went into effect on April 14, 2021. The second went into effect on August 5th and was called “London.” The Ethereum Improvement Proposal (“EIP”) 1559, a system for lowering transaction fee volatility, was a part of the London upgrade. The technique reduces the rate of ether inflation and may result in periods of deflation by causing a portion of the ether paid in transaction fees for each block to be destroyed rather than distributed to the miner.
A temporary fork in the blockchain occurred on August 27, 2021 as a result of clients using incompatible software versions.

Bitcoin 2.0 (old roadmap)

A series of three or more updates, commonly referred to as “phases,” known as Ethereum 2.0 (Eth2) were designed to switch the network’s consensus algorithm from proof-of-work to proof-of-stake and to extend the network’s transaction throughput via execution sharding and an enhanced EVM architecture.
On December 1st, 2020, the proof-of-stake Beacon Chain was deployed as the first of these three improvements, also referred to as “phase 0.”
There were ideas for a “early Merge” to speed up the transfer of proof-of-stake to Ethereum after it became clear that the Beacon Chain will be released considerably sooner than the latter phases of the Eth2 timeline.
Most crucially, the early Merge would continue to use the well-proven mainnet Ethereum clients alongside the new proof-of-stake consensus clients without requiring any transfer from Ethereum’s applications or users.

The phrase “Ethereum 2.0”

This was dropped in early 2022 in an effort to emphasize that there is only one Ethereum network and one ether cryptocurrency. The Eth1 blockchain was renamed to the “execution layer” as a result of the endeavor, and the Eth1 clients that it was connected to were reclassified as execution clients. Similar to this, the Eth2 blockchain’s related Eth2 clients were rebranded as consensus clients, and the Eth2 blockchain itself was renamed to the consensus layer.
In Ethereum, all smart contracts are publicly stored on each blockchain node, incurring expenses. Since a blockchain is a distributed computer system with great Byzantine fault tolerance, it is secure by default. A new block, which is linked to earlier and later blocks in a chain, records every new transaction. Fraudsters who wish to tamper with one transaction or block would have to tamper with all of the blocks before and after it, which is technically doable but very challenging.
The drawback is that because each node calculates each smart contract in real time, performance concerns can occur. The Ethereum protocol could handle roughly 25 transactions per second as of January 2016. The Visa payment platform, in contrast, processes 45,000 payments every second. This has caused some people to wonder if Ethereum is scaleable. The first day that Ethereum had more than a million transactions was December 19, 2016. Additionally, Visa has expressed interest in handling NFT and Ethereum transactions.
The second phase (Ethereum 2), which has been the focus of Ethereum engineers, was introduced at Ethereum’s Devcon 3 in November 2017.
Merkle trees are used on the Ethereum blockchain for security, scalability, and transaction hashing purposes. This offers storage savings, set membership proofs (also known as “Merkle proofs”), and light client synchronization, just like any other Merkle tree implementation. The network has had issues with congestion, such as those caused by Cryptokitties in 2017.
Ethereum is a permissionless, non-hierarchical network of computers (nodes) that constructs and reaches consensus on the blockchain, a continuously expanding collection of “blocks” (batches of transactions). Each block has a unique identifier for the chain that must come before it in order for it to be regarded as genuine. The ETH balances and other storage values of Ethereum accounts are changed whenever a node adds a block to its chain by carrying out the transactions in the block in the order they are listed. The “state,” or collection of these balances and values, is kept on the node independently of the blockchain in a Merkle tree.
