What is Ethereum? [The most detailed explanation of ETH virtual currency]

Surely you or those who see this article already know about Bitcoin? Ethereum (ETH) was once considered an alternative cryptocurrency to Bitcoin.

So is Ethereum special that can be compared with BTC? Why is it the second largest cryptocurrency on CoinMarketCap after Bitcoin?

How is it different from Bitcoin? Should I invest in this property or not?…

In this article, Blogtienao will bring you all the information about Ethereum.

Let's see the article together!

What is Ethereum (ETH)?

Ethereum is a blockchain distributed computing platform running on Blockchain technology, through the use of functionality smart contract (Smart Contract).

Ethereum can perform peer-to-peer network transactions and contracts through the cryptocurrency unit Ether (ETH).

Not only that, they are also considered a useful application platform and create their own distributed financial ecosystem.

Ethereum was introduced at the end of 2013 by Vitalik Buterin, with the desire to create a coin that overcomes the shortcomings of Bitcoin.

And with the above "mission", the capitalization of ETH has reached 25 million USD in the first sale.

According to the initial development roadmap, Ethereum will go through four important stages, including:

  1. Frontier
  2. Homestead
  3. Metropolis
  4. Serenity

As of December 12, Ethereum has completed 2019 phases and is about to enter phase 3.

However, there was an important change in this fourth phase when it was renamed Ethereum 2.0

What is Ethereum 2.0?

Ethereum 2.0 also known as Serentity. This is a collective name for several major Ethereum updates.

This update will solve Blockchain's trinity of impossibility: security, network scalability, and decentralization.

The main way to solve these 3 dilemmas:

  • Beacon Chain
  • Proof of Stake (PoS)
  • Sharding
  • eWASM

Ethereum 2.0 Chain Structure

Beacon Chain

Beacon chain is the core of Ethereum 2.0. This chain will run in parallel and cross-link between the Main chain and and the Shard Chain.

Proof of Stake (PoS)

PoS is a consensus mechanism that will replace the current mechanism of PoW (Proof of Work). The transition will be through a hybrid consensus mechanism between PoS and PoW – the Casper Friendly Finality Gadget (FFG).

You can roughly understand that the value and system of Ethereum will no longer depend much on miners and miners.

So the system will get stronger and stronger and will no longer be influenced or dominated by miners.

Normally, an Ethereum transaction needs a miner to confirm, otherwise the transaction will fail.

Watch now: What is Proof of stake?

Proof of Stake


Sharding is a method Scaling transaction throughput on-chain. The method is implemented by splitting the large database into small databases.

Small chunks of data are called 'shard'.


Ethereum-flavored WebAssembly (eWASM) is a limited subset of WebAssembly(Wasm) used for futures contracts.

Each shard will include 1 eWASM equivalent to the Ethereum virtual machine (Ethereum Virtual Machine).

Currently, there is no developer consensus for an EVM replacement. But the developer will have a plan.

How many stages to complete ETH 2.0?

To complete ETH 2.0, we need to go through 3 stages, including:

  • Stage XNXX
  • Stage XNXX
  • Stage XNXX

Stage XNXX

The first phase is the launch of Beacon Chain will deploy PoS on Chain. In this phase will also launch an asset class on the Beacon chain.

This asset class is called Beacon ether (BETH). BETH is considered as the authentic reward used to pay rewards to Staking people.

In addition, you can also own BETH by using ETH to buy. Each ETH will be equal to 1 Beacon ether.

At this stage, sharding, smart contracts and asset transfer are not supported yet. So you won't be able to withdraw BETH until sharding is possible in phase 2.

Stage XNXX

The next phase will shift focus to Shard Chain. Sharding breaks down state information into 'shards' to achieve scalability goals and improve network speed.

Stage XNXX

Phase 2 is considered the final stage of Serenity when it is completed base class upgrade and this phase is set to happen sometime around 2021.

During this phase, the shard chain will transition to a structured chain state that supports smart contracts and asset transfers.

What stage of ETH 2.0 are we at?

As shared by Vitalik at the 2049 Token Conference held in March 3, we have not yet entered any stage of ETH 2019 (as of December 2.0).

In the meantime, the Ethereum development team is finalizing the specifications. After that, the testnet was launched and some large companies tested the POS system.

However, according to Vitalik, the above stages can work in tandem without having to be in order.

Project's competitors

Ethereum used to be considered Bitcoin 2.0 but the success only stopped at the smart contract platform.

Although it is still the leader in smart contract platforms in terms of market capitalization, its influence is still small.

But the project competes with the one created to improve the limitations of the platform. Some of the names that can be mentioned are:

Nearly 60% of dapps run on the Ethereum network, 17% on EOS, 17% on Tron – according to DappRada. But the top 10 new dapps released on January 6, 1, Ethereum accounted for 2020% and Tron 40%.

ETH's Competitors

How does Ethereum work?

The Ethereum blockchain is essentially a transaction-based state recorder. In computer science, a state machine refers to something that will read a series of inputs and, based on those inputs, transition to a new state.

The state of Ethereum has millions of transactions. These transactions are grouped into blocks. A block contains a series of transactions and each block is connected to the previous block.

To make a transition from one state to the next, the transaction must be valid. For a transaction to be considered valid, it must go through a confirmation process known as mining. Mining is when a group of nodes (i.e. computers) use their computational resources to generate a block of valid transactions.

The process of validating each block by having a miner provide a mathematical proof is known as proof of work.

A miner who confirms a new block is rewarded with a certain amount of value for doing this work. That value is: The Ethereum blockchain uses an intrinsic digital token called Ether. Every time a miner proves a block, a new Ether token is generated and rewarded.

Client and node

The Ethereum network is made up of multiple nodes, each running compatible client software. There are two clients used by most nodes: Geth (written in Go) and Parity (written in Rust).

Application built on Etherreum

There are different types of applications that can be built on Ethereum. I will list for you the outstanding ones including:

  • Decentralized Finance (Defi)
  • Decentralized exchange (DEX)
  • Decentralized Application (Dapps)
  • ...

Let's evaluate each application together:

Decentralized Finance (Defi) and Ethereum


In the existing system all financial services are controlled by an intermediary. Whether it's transferring money, buying property, or making a loan, you have to go through an intermediary that charges a rental fee to mediate financial transactions.

Financial services, on the other hand, are based on Ethereum, connecting individuals peer-to-peer and allowing them to access assets more easily and at a more affordable cost.

Decentralized Finance Application on Ethereum

Ethereum is currently the platform with the most active defi applications. This section is probably also the applications you use the most, so I will list it first:

  • Stablecoin: Simply put, these are cryptocurrencies designed to minimize the impact of price fluctuations. The fiat-backed cryptocurrency is the most popular and the first stablecoin on the market.
  • Coinbase Wallet: A multi-currency wallet, Coinbase Wallet also provides access to Decentralized Web Applications (dApps) powered by Ethereum smart contracts.
  • Huobi Wallet: Multi-currency wallet, dApps browser and staking as a service for PoS networks.
  • MyEtherWallet: Free, open source, client-side interface for creating Ethereum wallets and interacting with dApps.
  • Trust wallet: Multi-currency wallet for storing BEP2, ERC20 and ERC721 tokens.
  • ...

These are the apps that people use the most. In addition, applications of ethereum with Defi can be listed such as: Lending, investment, Payment, insurance, prediction market, ...

Decentralized Exchange (DEX) and Ethereum


This form of understanding cuts the risk of asset hacks and many other risks.

Forms of decentralized exchange can be mentioned as: Peer-to-peer network... Along with the peer-to-peer network in addition to the decentralized application dapp, this is where users interact with smart contracts.

There is a very hot peer-to-peer trading platform called binance P2P. You can make purchases in VND.

Decentralized Applications (Dapps)

Decentralized application dapp with peer-to-peer network, this is where users interact with smart contracts. This section is the part that I expand to list more for you who are just starting to use Ethereum, which can be easily accessed:

What makes Ethereum dapps different

Applications built on Ethereum (dapps) can do things that regular applications cannot:

  • Create new digital currencies and assets.

  • Web applications are unstoppable and uncontrollable.

  • Build decentralized organizations, jointly managed assets or virtual worlds.

Dapps on Ethereum are web applications powered by Ethereum smart contracts. Instead of using a centralized server or database, these applications rely on blockchain as the backend for mathematical logic and program storage.

This leads to unstoppable potential uses: Anyone can deploy a clone and freely connect it to the public Ethereum network.

Ethereum Apps You Might Be Using 

Here is a list of Ethereum dapps you can use right now. Most are available to download for free through the Apple or Google Play stores or directly through their websites as demos, betas, or full releases.

Browsers, wallets and utilities:

  • MetaMask: Browser Plug-in application that allows to connect your device to the Ethereum network.
  • Status: Ethereum mobile browser with token wallet, chat and dApp portal.
  • Brave: A web and mobile browser integrated with BAT and ERC-20 tokens.
  • Opera: Dapp browser with built-in Ethereum wallet.
  • Ethereum Name Service: A utility for creating personalized and simple ETH wallet addresses.
  • Civic: Identity security and data management on the blockchain.
  • Alethio: Ethereum network analytics platform.

Other applications: 

In addition to wallets, websites or gadgets. The application of ethereum also spans many other fields such as: Platform, market, Social network, game, ...

Some examples for you to study are as follows:

  • IDEX: A decentralized exchange with real-time trading and high transaction throughput.
  • forkdelt to: A decentralized Ethereum token exchange.

Decentralized Ethereum Platform Review


  • Third parties cannot make any changes to the data.
  • Applications rely on a network formed around the principle of consensus, making censorship impossible.
  • Applications are well protected against hacking attacks and phishing activities.
  • The application never stops working and can never be shut down.
  • ...


Although it shows many benefits by decentralized applications. But besides that, we need to consider the following disadvantages:

Smart contract code is written by humans, so it's mostly only good for the people who write them. Code or oversight errors can lead to unintended adverse actions. If a bug in the code is exploited, the mining can be stopped apart from getting network consensus and having to rewrite the code.

This goes against the very nature of blockchain which is immutable. That is, no one can tamper with the data inside the blockchain.

You want to develop applications on Ethereum

Do you remember that I took the MetaMask application introduced above. It turns Google Chrome into an ethereum browser. MetaMask allows anyone to easily run or develop decentralized applications from their browser.

Although originally built as a Chrome plug-in, MetaMask also supports Firefox and the Brave Browser. MetaMask and a host of other browsers look set to make blockchain-based applications accessible to more people than ever before.

Even people without a technical background can now build blockchain applications. This is a revolutionary leap for blockchain technology that can bring decentralized applications to the flow like current technologies.

The Ethereum community consists of many technology developers, users, holders and enthusiasts around the world.

If you are a developer, there are many ways to participate in the Ethereum community: You can attend an event, join forums, contribute to a project on many levels.

Value of Ethereum

The mining source of the miners determines the value of ETH. Because this is a relatively young platform, often fluctuates in price, leading many people to think that they are of little value and should not be invested.

But if you are a person who learns and follows ETH closely, you will realize that it offers many opportunities for investors.

Ethereum is an open market that allows users to easily participate in buying and selling, exchanging with cash or Bitcoin through exchanges or between groups, organizations and individuals.

Especially in 2017 and 2018, Ethereum is the vehicle that helps many companies raise capital such as EOS, IOTA, etc.

In addition, in 2019, Ethereum still holds the 2nd position, but it is no longer a HOT channel to raise capital and is gradually being replaced by other channels.

Maybe they will use Bitcoin, Binance Coin or the Exchange Coins to raise capital. Therefore, the value of ETH will be changed, although the future is unknown.

So, remember to update the latest news from Blogtienao before making an investment decision!

Watch now: Binance Coin what?

Why does Ethereum not have a maximum supply?

Unlike Bitcoin, ETH has absolutely no supply limit. Why is that so? Will this have any effect on the price of ETH? In the future, will the supply of ETH be capped?

BTC and ETH supply

According to the development team, Ethereum will not have a limited supply. Because the team doesn't trust the same development path as Bitcoin.

For Bitcoin (built on algorithm Proof Of Work), for the network to be secure, miners need to work (create blocks).

In return, miners will be rewarded with BTC and transaction fees for successful mining. However, the reward budget is not permanent as the total supply of Bitcoin is only 21 million BTC.

When 21 million BTC are all mined, the reward for them is only transaction fees. At that time, there was no guarantee that miners would continue to work to secure the network.

That's why Vitalik Buterin realized that building ETH on the algorithm Proof Of Work and having a limited supply is not a wise move.

And the Ethereum 2.0 project was born, starting with the hardfork of Istanbul.

Ways to Earn Ethereum

Dig yourself or join mining groups

To mine ETH is a process of competing to solve a problem of miners. On average, every 10 minutes, one or a group of people will solve this problem and receive the corresponding amount of ETH.

However, the issue of investing in mining costs and electricity is something that needs to be carefully considered if you want to become a miner.

So you can find mining groups or pool capital with friends. In addition, you can also buy a digger yourself.

But, this form to payback capital, you need a lot of time and effort.

Invest money to buy Ethereum

In addition to becoming a miner, you can spend money to buy ETH to own them. You can buy from friends (if any) or go to reputable ETH trading sites.

In Vietnam, you can refer to these virtual currency trading pages in the next sections below.

Become an ETH trader

This method is called "Surf investment". Because the price of ETH is often volatile and there are times when the difference is up to several tens/hundreds of USD in a short time.

So many people rely on this point, take time to research, choose the right time to buy ETH at a low price and then sell it at a high price.

Should you invest in Ethereum or not?

Whether or not to invest in ETH depends on each person's point of view. In essence, you invest in this cryptocurrency just like you buy gold or play stocks.

If you know how to choose the right time to invest, the possibility of profit is very high; because the price of ETH is often volatile, similar to Bitcoin.

However, more and more countries accept Ethereum as a valid form of payment, even more so than Bitcoin.

Most countries do not accept Bitcoin because the management and security are not completely secure.

But with Ethereum, the developers have solved that problem, helping to ensure that transactions are safe, avoiding hacking.

The market for Ethereum is getting bigger and bigger. From a market capitalization of $25 million in 2014.

To date, the capitalization of ETH has grown to over $15.5 billion. For a rapidly growing market like Ethereum, investing in ETH seems like a very profitable opportunity.

Also you can watch Ethereum rate updated 24/7 by Blogtienao in real time to capture its price movements.

In addition, you should regularly update news about this coin if you have a direction to invest it. Because important news in the world is a factor that directly affects the price of any coin.

Buy and sell Ethereum at any exchange?

Ethereum coin is a very popular cryptocurrency. Most of the famous exchanges offer ETH trading pairs.

But with foreign exchanges, it will be more suitable for trading than buying and selling and long-term investment.

You can buy Ethereum at Vietnamese exchanges to be able to pay directly in VND through popular banks such as Vietcombank.

Some exchanges you can buy and sell ETH in VND: Vicuta floor, Coinhako exchange, Remitano floor, VCC.

The virtual currency blog would like to introduce to you some of the most reputable, cheap and best-supported Ethereum exchanges currently like Vicuta.

In which, Vicuta market is still the most reliable address for the majority of Vietnamese investors. If you are intending to invest in Ethereum, I also recommend using Vicuta exchange. .

Buy and sell Ethereum

Which wallet is safe to store Ethereum in?

Before buying Ethereum, what you need to do is create a wallet address (Wallet) to store your Ethereum.

So which wallet is safest and easiest for new investors to use? You can use “Online/hot wallet” or “Offline/cold wallet” depending on your needs.

If you often buy and sell, you should use a hot wallet, and if you plan to hold for a few months or a few years, you should use a cold wallet.

  • Hot wallet are web-based wallet platforms. Some of the most popular and widely used wallets are Blockchain.com, CoinBase or MyEtherWallet. In particular, MyEtherWallet is a specialized wallet to store tokens that are run on the Ethereum platform (ERC20).
  • Cold wallet are software wallets or USB wallets (shaped like a USB), which can be mentioned as Ledger Nano S, ledger nano X or Safe deposit.

However, one thing to keep in mind is that cold wallets are always safer than hot wallets.
