What is Ethereum? How to buy Ethereum and its wallets
Imagine a decentralized world. A world where people directly, without the need to trust corrupt intermediaries, deal with decentralized programs, sign contracts, and use a variety of financial and non-financial services; Systems controlled by the people never stop and no one can interfere in their work. Atrium has stepped in to achieve this goal. In this article, we will first explain the simple atrium and its various aspects so that you can better understand this complex network. Then we review the history of Atrium and its future plans. We also take a look at the price of Atrium. At the end of this article, you will get acquainted with the best wallets of this digital currency and learn how to buy Atrium.
At its simplest, Atrium is a free infrastructure based on China Blockchain technology on which decentralized computer applications can run. Atrium decentralization means that the system alone does not belong to anyone and is not controlled by one or more specific individuals. Everyone can own this network and everyone can play a role in controlling it. Thanks to the distributed and decentralized structure of Atrium, once a program is implemented on the Atrium network, it can no longer be stopped and manipulated, even if its creator wishes.
“Atrium is a decentralized platform for smart contracts,” Atrium’s official website said. “There is no possibility of malfunction, censorship, fraud, or interference by third parties for programs running on this network.”
In the following article, you will get acquainted with the concept of the smart contract.
What is the purpose of Ethereum?
When asked about the purpose of creating the network, Joseph Lubin, one of Atrium’s major developers, replied:
Atrium was created so that we would not need any bank, company or institution other than ourselves to do my life.
In 2008, an anonymous person named Satoshi Nakamoto introduced Bitcoin. It can be said that Bitcoin is the first decentralized, digital and distributed monetary system. With the help of a concept called “blockchain”, the Bitcoin network distributes money transaction information to computers around the world instead of banking and central servers, allowing it to deploy value (money) anywhere, regardless of companies, governments or intermediaries. Transmit from the world.
Atrium goes one step further and enables decentralized execution of computer code (smart contract) so that we can decentralize other processes in addition to money.
The introduction paper (idea) or Whitepaper of this project was published in 2013 and in 2015, the Atrium network officially started operating. The main protagonist of the project is a young Russian-Canadian named Vitalik Buterin, who was a supporter of Bitcoin and, inspired by Bitcoin, came up with the idea of “decentralizing everything”.
Decentralize everything
To better understand Atrium, consider a program like Telegram or Instagram. Today, millions of people around the world use these useful communication and messaging programs. But there is one very fundamental issue about them that few people pay attention to: these programs are focused.
For example, Instagram belongs to Facebook. The company may, in accordance with its policies, delete content, block access to certain people, or even sell users’ private data. Theoretically, with Atrium, this decentralized platform could create an Instagram where, instead of Facebook, the real owner is its users and they control their data only themselves.
Of course, it should not be forgotten that Atrium is still at the beginning of the road, and at least at the present time, its technical problems do not allow us to build a large system like Instagram on it.
As another example, with the help of this network (if there are some necessary conditions), free and transparent elections can be held; An election in which there is no possibility of fraud.
Any other centralized service can be decentralized with Atrium. Important matters such as payments, insurance, voting, banking, lending and many of the services that intermediaries now provide will be decentralized to this network.
Anyone can develop their own decentralized application (Dapp) in the open atrium network. Before the advent of Atrium, developers had to code a separate Chinese blockchain from scratch to build their own digital currency, but today everyone can easily use the Atrium China blockchain for their own independent digital currency projects or tokens without building a new blockchain. (Token) Make.
Ether; Atrium Digital Currency
The digital currency of the Atrium network is called “Ether” and its abbreviation is ETH. This asset is considered as the monetary unit of the network as well as a way to pay expenses and commissions. Therefore, as the acceptance of the Atrium network increases, so does the value of ether in theory.
Among the members of the digital currency community, the digital currency of the Atrium network is also called Atrium, but in fact it is called Ether. So if you see “Atrium Purchase”, “Atrium Analysis” and جایی somewhere, it means the same ether.
Atrium: A blockchain-based network
Ether: Atrium’s digital currency.
Many people today are investing in this digital currency in the hope of Atrium’s future. Ether can be purchased from digital currency exchange sites and stored on wallet software on a mobile phone or personal computer. Read more about ether and how to store and buy it.
Similarities and differences between Atrium and Bitcoin
Since Bitcoin is the first Chinese blockchain network and the first decentralized digital currency, the best way to fully understand Atrium is to examine its similarities and differences with Bitcoin.
Atrium and Bitcoin similarities
Atrium also has its own independent China bloc
Like Bitcoin, Atrium also has a blockchain. Information about smart transactions and contracts is recorded on the Chinese block. Blockchain is a secure, unchanging digital notebook for storing data and information.
Atrium is also public and without a permit
Like Bitcoin, the Atrium network is public and accessible to anyone. Anyone can use this network to create smart transactions or contracts, without having to get permission from anywhere. Of course, if one wants, one can create private platforms on the Atrium network, but the Atrium blockchain itself is transparent, free and public.
Atrium is also based on proof of work (extraction)
Like Bitcoin, Atrium is based on mining. Individuals wishing to participate in the blockchain process must allocate the processing power of computer hardware to the network to participate in the mining operation, and the network will reward the extractors in return for this processing power, which will ultimately secure and verify the transactions. he does.
Of course, according to a pre-defined program and in a project called “Atrium 2.0” (ETH 2.0), this network is supposed to be more scalable (faster and cheaper transactions), instead of the Proof Of Work algorithm from the stock proof algorithm ( Proof Of Stake). The exact time of implementation of this update is not known, but atrium mining will continue at least until the end of 2020.
In the stock proof method, individuals must purchase ether and allocate it to the network in a wallet to participate in transaction validation and block creation. In this way, they can participate in the verification of transactions and receive new units of digital currency (ether). Participants charge a fee for network transactions. According to this approach, you no longer need to buy expensive hardware to participate in the network.
Phase Zero Atrium 2.0 will be implemented in 2020. Atrium stock proofing will be activated in this phase, but mining will continue. In Phase One, the Atrium China blockchain is set to fully demonstrate small stocks and end mining, but as we said, the timing of Phase One is not yet clear. More about the future of Atrium is provided in the following article.
Atrium has its own digital equivalent
The internal digital currency is the Atrium Ether network, which can be exchanged for other currencies and assets. Ether ownership is tracked just like Bitcoin (BTC) ownership on the Chinese blockchain. Ether is also called “Atrium Network Fuel” because its main use is the fee and motivation to participate in the network.
Atrium and Bitcoin differences
Atrium transactions are faster
In Bitcoin, on average, blocks containing a transaction are created every 10 minutes, but in Atrium this time is only 14 seconds. Of course, the size of the block is also
important in discussing the speed of transactions, which is limited to 1 MB in Bitcoin. Looking at block time and block size, it can be said that Bitcoin currently performs a maximum of 7 transactions per second, but Atrium can process up to 16 transactions per second. As promised by the Atrium Development Team, this number could reach hundreds of transactions in future updates.
Atrium can easily execute smart contracts
Bitcoin can also be used to create smart contracts, but the network language of the script is very rudimentary and makes it difficult for developers. On Atrium, programming code can be implemented much faster and easier. Atrium smart contracts are so-called “complete Turing”; That is, they can perform any calculations and operations that are needed.
The number of ether units will be unlimited
One of the main differences between Bitcoin and Atrium is the number of units (supply) of the two. Bitcoin has supply restrictions, but unlimited ether will be available.
According to the Bitcoin protocol, only 21 million units of this digital currency are extracted. Currently, bitcoin miners receive a reward of 6.25 bitcoins per 10 minutes from the bitcoin network, which is called a “block reward”. The Bitcoin block reward is halved every four years during an event called “Hawing”, and for this reason, the extraction of all bitcoins will take until 2140. After that, miners will only earn money with transaction fees.
There are no restrictions on Atrium, and more than 112 million ethers have been extracted at the time of writing. Of course, this does not mean rampant inflation in Atrium, but proponents of the project believe that a little inflation is needed to have a perfect monetary system. The atrium block reward is currently 2 units of ether, so an average of 2 ethers is extracted every 14 seconds, and by these criteria we can say that the annual inflation of atrium is currently about 4%. In the Atrium 2.0 update, inflation is expected to be greatly reduced to the minimum required to motivate network participants.
What is an Atrium Smart Contract?
A smart contract is a code (software) that runs on a blockchain. The software executes a series of commands automatically if a predetermined situation occurs. Once a contract is signed on a free China block such as Atrium, no one can prevent it from being implemented, and in fact the contract has an enforcement guarantee.
Before we go into more detail about the smart contract, let’s first review the description of a normal contract.
A normal contract is an agreement between two or more people that commits them to something in the future. For example, Behzad undertakes to pay Majid a monthly fee for using the house for one
year, which is called a lease or “lease”. As another example, Amir Company guarantees that in exchange for a sum of money, it will pay for possible damages to Saeed’s car in future accidents, which is called an insurance contract or “insurance policy”.
What makes the difference between a regular contract and a smart contract is that in smart contracts, computer code solves the problem of the need for trust. As we have said, once a smart contract is executed on a free China block like Atrium, it can no longer be stopped and no one can stop it. With smart contracts, you can create programs and projects that continue to work without any intermediaries and disabling, so that even
the smart contract developer herself can not change the smart contract code registered in the Chinese block.
For example, using a smart contract can make the lease process decentralized and smart. Suppose Behzad rents Majid’s house with a deposit of 100 million Tomans and a monthly rent of 2 million Tomans for one year. Therefore, with the help of programming languages in the smart contract code, it is stipulated that Behzad first pays 100 million Tomans and 2 million Tomans per month in the form of digital currency (for example, Atrium) for rent to the smart contract address. We can adjust the contract so that if the rent is delayed, it will deduct from the deposit until the deposit expires. Then we can
specify in the smart contract code that if the deposit is over and Behzad still does not pay the rent, she will be notified to vacate the house.
Atrium Smart Contracts can be used in the areas of financial transactions, record keeping, property ownership, collateral, insurance, scientific research, medicine, elections, product development, supply chain, and in all areas where we want to minimize the need for trust. Today, developers can use smart contracts to build their own projects using the Atrium China block and even create a digital currency (token) without the need to create a new China block. The programming language for smart contracts is Atrium Solidity.
It should be noted that at the present time, smart contracts are struggling with many problems and still can not be used as they should be in many areas. The most important current problems of smart contracts are the following:
Legal and Governmental Problems: At present, governments do not recognize smart contracts, and for example, owning a home with digital currency and tokens is not yet legally accepted.
Human error: Although smart contracts have a performance guarantee, the contract cannot detect whether a code is malicious or not, and executes it without commas. Therefore, if there is a bug or critical problem in the contract code, the contract will not be executed according to the wishes of the parties.
Implementation costs: Flawless smart contracts have to be written by skilled programmers, and there is still no proper service that even ordinary users can sign at low cost.
Attention:
Many fraudulent schemes, including Doubleway, Eco Smart, Bank of Thrones, and others, are trying to empty the pockets of ignorant people by misusing the name of smart contracts and promising astronomical profits. Remember that a smart contract is an underlying innovation and, like a content-free website, is completely useless if there is no economic activity in the smart contract.

How does Atrium work?
A detailed description of Atrium’s work is not included in this article, and of course you do not need to know exactly how this network works to work with Atrium, just as you do not need to be familiar with the Internet infrastructure to work with the Internet. However, in the following, we will briefly review how this network works without technical details. For a detailed and technical study of the Atrium network, you can read the article “How does Atrium work?” Read.
Blockchain and nodes
The Atrium network consists of thousands of computers around the world that maintain a digital office (blockchain). Transaction information is written on this digital ledger and each computer has a copy of it. These nodes are connected to each other and check every transaction sent to the Atrium network to make sure it is valid. The distribution of these nodes means that the network does not have a central point of penetration, that is, the output or error of a node does not cause a problem to the network.
Mining
To prevent fraud, Chinese blockchain data, and system attacks, a decentralized solution is needed so that a saboteur can not proceed without the permission of the majority.
Mining, scientifically known as Proof Of Work, is one of the most common methods for consensus building and security of Chinese blockchain networks. According to this algorithm, the process of creating blocks is competitive, and anyone who wants to be involved in creating blocks containing transactions must solve a complex mathematical equation with the processing power of computer hardware. Whoever gets the answer sooner will be the winner of this competition and will receive a reward after creating the block.
This reward in the Atrium network is Ether digital currency. Miners also receive transaction fees. Currently, the extraction bonus for each block is 2 units of ether, which is given to the miners approximately every 14 seconds.
Therefore, miners (or mining nodes) allocate a large amount of processing power to the network, which is equal to the power of several supercomputers. In this case, if someone wants to attack the network or change the blockchain, she has to have the processing power of more than half of the miners, which has no economic justification for large networks such as Atrium. In other words, in addition to the fact that it is very difficult to provide such processing power, if someone has this processing power, she can extract it herself instead of attacking the the network and get a lot of rewards.
The more the number of miners increases, the security of the network will also increase, and so trust will increase.
Therefore, do not forget to do any change in the Atrium network, contributors must declare their agreement, and accordingly, any sabotage or effort will fail to change the registered information.
In the Atrium network, it is designated every 14 seconds of new blocks. Now, for example, a powerful miner will enter the network and can find the answer to the blocks in 5 seconds. In this case, the network makes the math equation harder to increase the “hardness of extraction”. In the fact that the number of mines, the network reduces the extraction hardness network to find an average response in the same 14 seconds.
Since we deal with computer codes with computer codes, Aryum intelligent contracts are first written in a high-level language (language that can understand), such as saline, and then turn into bytes to bytes. Finally, these codes are implemented in a virtual space called “Atrium Virtual Machine.” Any computer that connects to the Atrium network runs a smart contract inside its virtual machine. Using the virtual machine, any processing is applicable and the Australian network does not harm malicious code.
Ether
Ether like Bitcoin (BTC) is a digital currency that can easily be transferred value. However, the goal is slightly different with Bitcoin. This digital currency has been made to pay for costs and incentives for contributors to continue the activity of Atrium. If the ether was not a key asset, who would attend work as a minister or contributor to the network? That is why they also say to the ether “Atrium Fuel”. If Bitcoin is “digital gold”, ether is “digital oil”.
The use of the Atrium Network Services and the creation of the program requires the payment of fees and this fee should be paid ether. Attests paid for fees are awarded to minors that maintain network security.
Unlike Bitcoin, which is limited to 21 million units, the production of ether is currently no limits. At the time of writing this, 120 million ether units have been extracted. Of course, although the number of ether units is unlimited, the production of new units is not very fast, and its inflation is about 4%. In the eterium 2.0 update, only as much as the network needs.
Ether like Bitcoin is sold and sold in digital currency exchange and its price is constantly fluctuating. This digital currency is stored and transferred on the wallets. In the following, you read about the history of Ether price, the wallets and how to buy this cryptocurrency.
