ETHER 101: Its History, Future, and Features Ethereum is an open-source platform running blockchain technology that is used for creating decentrali sed applications known as DApps. Meanwhile, Ether is the cryptocurrency required to use the Ethereum network therefore it is referred to it as the “fuel” for the network. DApps are smart contracts that facilitate transactions trustlessly (i.e., without trusted third-party acting as an intermediary). Ethereum is the world’s first programmable blockchain and Ether (ETH) is the token that power operations on the Ethereum network. Ether is the currency that is required to use the Ethereum network.
1.0 INTRODUCTION TO ETHEREUM ETHER SUMMARY STATISTICS With the success of Bitcoin, the founder of Because Bitcoin’s blockchain technology is Ethereum Vitalik Buterin foresaw the broader limited to perform a small set of functions As of May 18th, 2022 possibilities of the blockchain technology and such as who can send how much Bitcoin, the in 2013 proposed Ethereum in a white paper. founders of Ethereum were able to utilise Asset Ether (ETH/ETX) He was joined by likeminded individuals and Bitcoin’s decentralised ledger technology and Inception of Network July 2015 in 2015 they launched Ethereum.

2.0 A BRIEF HISTORY OF ETHEREUM Let us take a look at a brief history of Ethereum We will focus on three main components of its history 1. The period prior to the launch of Ethereum 2. The DAO exploit and 3. Ethereum 2.0 and the main four stages of network upgrades. 1. Prior to Ethereum Launch: marketplace of financial services, games and On November 27, 2013, Vitalik Buterin released 2013 – 2015 apps that cannot steal your data or censor you. the white paper where he proposed Ethereum. The following year on April 1, 2014, Dr. Gavin With the success of Bitcoin’s platform, We now know that Ethereum is the Wood released the Ethereum yellow paper Vitalik Buterin the co-founder of Bitcoin infrastructure for running DApps. It is very where he defined the technical definition of magazine, was able to foresee how blockchain important to understand that “Ethereum the Ethereum protocol. The same year on July technology could be utilised for more than just is a platform, not a currency, while Ether 22, 2014, Ethereum’s initial crowd sale raised the transfer of digital currencies. Bitcoin is (ETH) is the token that powers operations $18 million and lasted 42 days where ETH was written in a “turing incomplete” programming on the Ethereum network. Therefore, ETH bought using Bitcoin. The initial crowd sale language that is only able to complete small is the currency that incentivises the use of helped fund the continued development of sets of tasks primarily the transfer of Bitcoin Ethereum.” While ETH can be thought of as the software platform. A year later, on July 30, from one account to another. the cryptocurrency of the Ethereum network, 2015 the Ethereum network was launched with metaphorically speaking, it is more accurate to Vitalik and other Ethereum builders were a supply of 72 million ETH. refer to it as the “fuel” of the network. . −ETH’s able to set Ethereum up with Solidity, a main purposes serve to (1) to store value in “turing complete” programming language ETH, (2) settle transactions by allowing users that allows Ethereum’s blockchain to do more to send or receive payments in ETH, and than just transfer digital currencies. It allows (3) facilitate network operations (i.e., power for programs, known as smart contracts, DApps) via transaction fees paid in ETH, which to be uploaded onto the blockchain and are based on the computational costs of run autonomously.

Amazon. DApps are: Ethereum. While Ether can be thought of as A smart contract is a collection of code (i.e., the cryptocurrency of the Ethereum network, • Decentralised meaning they are functions) and data (i.e., state) that resides at a metaphorically speaking, it is more accurate to independent, and no one can control them specific address on the Ethereum blockchain. refer to it as the “fuel” of the network.

(DApps) The Ethereum network contains DApps in Smart Contracts A DApp is an application built on the Ethereum finance, arts and collectibles, gaming and network that combines a smart contract technology. Some of the most popular DApps Smart contracts are software programs that (back-end) and a front-end user interface. created on the Ethereum network are: Uniswap are written and then uploaded to the Ethereum A DApp has its backend code running on (finance), Dark Forest blockchain. Smart contracts can help you a decentralised peer-to-peer network like (gaming), Foundation (collectible), and Ethereum. Contrast this with an app where PoolTogether (finance). 6
4.0 IMPORTANT FEATURES OF ETHEREUM Decentralised Autonomous Decentralised Finance (DeFi) Ethereum Virtual Machine (EVM) Organisations (DAOs) DeFi is a collective term for financial products The EVM running on the Ethereum blockchain can be thought of as a global decentralised DAO is a decentralised autonomous and services that are accessible to anyone computer containing millions of executable organisation that is run through rules who can use Ethereum – anyone with an objects, each with its own permanent data encoded in smart contracts. A DAO’s financial internet connection. With DeFi, the markets store. It was created by Dr. Gavin Wood and transaction record and programmed rules are always open and there are no centralised detailed in the Ethereum yellow paper. The are maintained on a blockchain, that function gate keepers who can block payments or deny EVM handles the creation of DApps, DAOs and without a governing body. DAO governance is access. Services that were previously slow, smart contracts on the network. The EVM is a completely transparent and allows for unique arbitrary, or regional are automatic and safer quasi–Turing-complete state machine; “quasi” social coordination mechanisms not available now that they are handled by code that anyone because all execution processes are limited to in the corporate world. can inspect and scrutinise. a finite number of computational steps by the These are financial products that focus amount of gas available for any given smart Non-Fungible Tokens (NFTs) on building out financial services using contract execution. NFT stands for non-fungible token. Non- cryptocurrencies. They offer the likes of fungible is an economic term that you could lending, borrowing, earning interest, and use to describe things like baseball cards, private payments to anyone in the world at diamonds, and land. These things are not any time. interchangeable for other items because they have unique properties. “NFTs are tokens that can be used to represent ownership of unique items. They let us tokenise things like art, collectibles, and even real estate.” They can only have one official owner at a time, and they are secured by the Ethereum blockchain – no one can modify the record of ownership or copy/paste an existing NFT. 7
4.0 IMPORTANT FEATURES OF ETHEREUM Mining network. Originally the block rewards were It is interesting to note that as Ethereum moves 5 ETH per block then in 2016 they dropped to proof-of stake−the mechanism of “fee The word mining originates in the context of to 3 ETH per block and in 2017 the block burn” will be introduced into the network. This the gold analogy for crypto currencies. Gold reward dropped to 2 ETH. There is currently a means instead of the transaction fees going or precious metals are scarce and so are supply of 115.94 million ETH and in 2050 the to the miners they are burned, increasing digital tokens where, the only way to increase estimated ETH supply will be 135 million ETH. Ether’s scarcity . If fee burn exceeds the Ether the total volume is through mining. This is issued to stakers, this can lead to a decrease appropriate to the extent that in Ethereum too, in Ether supply. the only mode of issuance post launch is via mining. Unlike these examples however, mining is also the way to secure the network by creating, verifying, publishing and propagating Ethereum's Issuance Rate Perpetually Declining blocks in the blockchain. July 30, 2015 - May 27, 2021 Mining Ether = Securing the Network = 140,000,000 45,000 Verifying Computation 40,000 On July 30, 2015, at the inception of Ethereum 120,000,000 ETH Supply In Circulation 35,000 ETH Issued per Day 72 million Ether were created through the initial 100,000,000 crowd sale that took place from July 2014 that 30,000 lasted 42 days and raised $18 million. No more 80,000,000 25,000 than 18 million Ether were to be issued every 60,000,000 20,000 year, which is about 25 percent of the first 15,000 issue but a declining inflation rate thereafter. 40,000,000 In Ethereum the mining difficulty is adjusted so 10,000 there is one block mined every 12 seconds on 20,000,000 5,000 average.

It is a difficult computational puzzle used to produce new blocks that are added using specialised computers. of stake” was taken. This is a to the blockchain. The main goal of the proof- significant milestone for the of-work protocol is to deter attacks on the The amount of work done by network and ensure network security (e.g., a particular miner determines development of Ethereum, preventing “double spending” of tokens).

5.0 PROOF OF WORK VERSUS PROOF OF STAKE Proof-of-work consensus requires miners to Ethereum Energy Consumption solve very difficult mathematical equations of May 20, 2017 – May 2, 2021 trial and error in order to find the nonce for a 60 block. Only blocks with a valid nonce can be added to the blockchain. This process is very 50 costly, because many miners are battling to find the valid nonce for one block and only the 40 winner gets the reward. To put in perspective, TWh 30 “The Ethereum network currently uses 51TWh of electricity per year which is as much as the 20 country of Portugal under its proof-of-work consensus mechanism.” To solve the issue 10 of energy intensity and reduce its carbon 0 footprint, Ethereum will perform a network 5- 18 7- 18 9- 18 1- 19 7 7 11 -17 1- 17 3- 18 11 -18 1- 18 3- 19 5- 19 7- 19 9- 19 11 -19 3- 20 5- 20 7- 20 9- 20 11 -20 1- 20 3- 21 5- 1 21 -2 -1 -1 upgrade so that proof of work consensus will 0- - 2- - - - - 0- - - - - 0- - - - - 0- 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 -2 -2 -2 -2 5- 7- 9- be replaced via proof of stake.

Once a validator by 99.95% .” In addition to vastly reducing the same thing as miners in proof of work is selected, they have the exclusive right to Ethereum’s carbon footprint proof of stake as it relates to-creating new blocks. Vitalik create a block. In this context, proof of stake offers the potential to make Ethereum more Buterin said, “proof-of-stake operates under a requires virtually no energy relative to proof decentralised and more secure. fundamentally different principle than proof of work.

This gives Ethereum a tremendous High Gas Prices Ethereum is switching to proof of stake in late advantage over other protocols. During the first quarter of 2020, rising demand 2021 early 2022, which will greatly reduce the drove Ether gas prices to the point where energy expenditure on the network. This will transacting lower value transactions on the lead to drastically reduced inflation rate, which platform simply was not viable anymore. is expected to be under 1% per year. Fee burn is the mechanism where the transaction fees on the Ethereum network will be burned. This can have an interesting outcome where the Ether burned from transaction fees could surpass the amount of Ether issued to stakers which can lead to negative inflation rate and may lead to upward price pressure as demand outstrips supply. 12
7.0 WHAT IS THE DIFFERENCE BETWEEN ETHER AND BITCOIN? ETHER and Bitcoin are the two largest and Ethereum is the world’s first programmable not have a hard cap, but it does have a limit most popular cryptocurrencies. Although blockchain and Ether (ETH) is the native of 18 million units per year that makes Ether they have some similarities the two have currency of Ethereum. While Ether is the resistant to inflation. Currently Ethereum uses major differences. Comparing the two is like cryptocurrency of the Ethereum network, the proof-of-work consensus but soon it will comparing apples to oranges. metaphorically speaking it is more accurate switch over to proof-of-stake to help deal with to refer to Ether as the “fuel” to the network. scalability and energy consumption issues. Bitcoin is the largest cryptocurrency that Therefore, Ether is the digital token that Below we will outline the differences between was created in 2009 by Satoshi Nakamoto. incentivises the use of Ethereum. Ether does the two biggest cryptocurrencies. It is a decentralised digital currency that you can use to buy, sell and exchange without any intermediary involvement such as banks.
