What is Ethereum?
Ethereum is both a cryptocurrency and a functional blockchain in one. Ethereum is an open universal platform for developing decentralized applications based on blockchain and smart contracts. Ethereum has taken the potential of blockchain technology in the financial industry to a new level. The main value of Ethereum is its Ethereum Virtual Machine (EVM), which allows developers to create various projects using a Solidity programming language.
To date, Ethereum still works with the Proof of Work (PoS) consensus mechanism. Nevertheless, to reduce energy consumption and enable Ethereum unlimited scalability and low gas fees, the developers plan to switch to Proof of Stake (PoS). The full transition to PoS is planned for around September 15, 2022. As a result of the transition, the Ethereum mainnet will merge with the PoS-based beacon chain.

Ethereum Use Cases
- Various blockchain projects are being built on the Ethereum platform, including DeFi apps, crypto lending platforms, yield farming and many others. The most famous Ethereum-based projects are MakerDAO, Lido, Uniswap, Aave and Compound.
- Many ICOs (Initial Coin Offerings) are held on the basis of the Ethereum platform. Developers use a single standard for issued tokens – ERC-20. In addition, Ethereum is used to tokenize real-world assets (pegged to precious metals, fiat currencies, etc.). Thousands of NFTs based on the ERC-721 standard are also being mined.
- Ethereum is the leading platform for launching DAOs. Hundreds of projects are using Ethereum for various targeted DAOs: charity, freelance, venture investing and more. All this is due to the widely recognized reliability, decentralization and security of the platform.
- ETH is accepted as a payment option by thousands of traders worldwide. Users can pay for airBaltic trips, Time Magazine subscriptions, Phillip Plein clothes and many other goods and services.
- Despite slow transactions, ETH is often used for peer-to-peer transactions. Users send ETH to their friends, relatives and business owners to business partners. With the move to PoS, fees are expected to decrease and transaction speeds to increase, making ETH an even more popular coin.
- Since Ethereum is the second most popular cryptocurrency and the first major smart contract platform, many users use ETH to store value. The value of ETH is expected to grow only with the transition to PoS.
ETH token
A key component of the network is the ETH coin. In fact, it is the “fuel” that runs the network and the EVM. ETH is used to pay gas fees and access all Ethereum-based applications and services. With Ethereum, there is no clear mechanism for determining the number of coins in the system and the reward for the block. Instead, the minimum required emission is used. Ethereum automatically reduces the block reward to the level needed to keep the network safe. Thus, the number of coins in the system is not fixed, but the required minimum.
After the merger, ETH will become a PoS coin that users can wager to keep the network secure.
How do I store ETH?
The rules for storing ETH are no different from storing other cryptocurrencies. It is important to always remember that whoever holds the private keys also owns the cryptocurrency. There are four main types of wallets:
- Hardware. Hardware crypto wallets are physical devices. The devices themselves do not allow cryptocurrency transactions. To access transactions, developers of such vaults usually create separate applications.
- mobile phone, mobile phone. Such wallets belong to the software category. They are downloaded and installed on customers’ smartphones or tablets. Typically, mobile wallet developers only create versions for iOS and Android. Such wallets are very convenient, since transactions can be carried out on the go.
- Writing desk. They can be downloaded and installed on personal computers (PCs). At the same time, developers of desktop crypto wallets often create three versions – Windows, Linux and macOS.
- Browser based. This type is often referred to as web storage. From a technical point of view, these are software wallets. Such cryptocurrency products do not need to be downloaded and installed. They are available in common browsers.
Most users save ETH in hot wallets to have quick access to the Ethereum blockchain. So if you need a wallet to carry out everyday transactions, a mobile or browser wallet is your best bet. SimpleHold is a non-custodial wallet that has two versions: mobile application and browser extension. Our wallet is characterized by simplicity, transparency and security as we do not have access to your keys or transactions, giving you maximum privacy.
