A review of the best platforms to create smart contracts Many platforms have emerged to create smart contracts, we chose the most famous to analyze them in-depth: how they work, characteristics, speed, scalability, and much more in this complete analysis on Ethereum, EOS, and TRON smart contracts. For some time now, the birth of new platforms aimed at the development of smart contracts -or smart contracts- and decentralized applications has spread throughout the cryptocurrency market. All of them offer particularities that make the difference when building in any of these systems. While there are a large number of platforms, at Cointelegraph we decided to focus on the 3 most renowned: Ethereum, EOS and TRON. Ethereum Ethereum (ETH) is a distributed ledger and decentralized computing platform with smart contract capabilities. It was proposed at the end of 2013 by Vitalik Buterin and financed through ICO in July and August 2014, which generated approximately USD 15,571,000 with a cost per token of $ 0.311, the ICO of ETH was one of the most profitable as far as there is a record. Subsequently, the main Ethereum network was launched on July 30, 2015, giving way to a variety of applications and development options to the community. Its consensus algorithm works through the Proof of work mechanism or proof of work that, through a coarse network of miners, transactions are validated and verified to be added to a block. After Bitcoin, Ethereum is the most valuable blockchain project by market capitalization. It is one of the first large blockchain networks built specifically for decentralized applications. Tron The development of TRON (TRX) is a smart contract platform in charge of granting a more optimal development for the execution and scalability of decentralized applications (Dapps). Founded by Justin Sun in mid-2017, TRON raised a total of $ 70 million through an ICO on the Ethereum network for a price per token of $ 0.00186 before launching its mainnet in May 2018. According to their whitepaper, the TRON codebase was originally pulled from an Ethereum fork and uses a copy of Solidity's smart contract language for the setup of its contracts. Solidity was the most commonly developed and used programming language on Ethereum. As a result, smart contracts and Ethereum token standards are compatible with the TRON ecosystem. TRON blockchain development uses a different consensus mechanism than Ethereum to aggregate and verify transactions on its network. Instead of using Proof of Work like Ethereum or Bitcoin where miners produce blocks for the network, TRON uses something called Delegated Proof of Stake (DPoS) where 27 elected Super Representatives produce blocks for the network. This consensus mechanism allows TRON to achieve much faster transaction rates than other chains. EOS EOS (EOS) is a smart contract computing platform designed to host decentralized application development (Dapps). Its operation began on June 14, 2018, after raising USD 4.2 billion in an ICO that lasted for one year and an average price per token of USD 5.74. The EOS blockchain uses a Delegated Proof-of-Stake (DPoS) consensus mechanism to confirm its consensus, where 21 community-chosen block producers actively maintain and build the network. https://www.blockchainx.tech/tron-token-development

Ethereum: the basis of the new web and the future of the Internet? Interested in an ether blockchain fired last year as developers turned to it to create various decentralized financial projects and digital tokens called non-fungible tokens (NFTs). The boom has created a powerful net effect, as increased activity draws more and more developers to Ether. This could make it the platform for web 3.0, where a host of decentralized applications may one day challenge Big Tech's offerings. “60% to 70% of the industry is powered by a development of ethereum, ” says Sandeep Nailwal, co-founder of Polygon, one of the many companies that trade in currencies. As a result, the price of the digital currency ethereum multiplied by nine. The value of the featured ether tokens is $ 350 billion, more than 40% of the value of bitcoins, and the percentage has more than doubled in the year. But there are still fundamental questions about whether Ethereum, which is far behind in its technical updates, will be able to compete with more agile rivals and whether there is consensus on its long-term role. Until there is an answer to this question, it is likely that the price of ethereum tokens is volatile. The increase in the price of Ethereum is due to two hopes. One is that it has entered a new phase where the number of tokens in circulation will increase much more slowly than before or even decrease. In fact, the offer has already been reduced after a change last month in the way of validating transactions on the network. Some of the tokens that were previously paid as commissions to people who validate transactions are being destroyed. Another big step could occur later this year or early next when the current "proof of work" system is replaced, which consists of coin miners contributing their computing power to the network in exchange for receiving cash. ethers - by "proof of stake", in which validators deposit on the development of ethereum network. This change has important monetary implications. At the end of last year, a gambling test chain was launched. Approximately 6% of the ether supply has already been deposited there by its holders to support transactions, thus obtaining an annual return of up to 5%. This is an indication of the amount of ether that will be out of circulation once the transition is complete. different bitcoin, ethereum was not created with a clear monetary vision nor was there an upper limit on the number of tokens that could be created. But a big reduction in the supply of tokens could change that, making it more attractive to investors. Its creator, Vitalik Buterin, stated that it will adapt to the needs of its users, as changes are made to the way in which tokens are created and therefore to its long-term offering. https://www.blockchainx.tech/erc20-token-development

TOKEN ERC: most common standards and implementation ERC-20 Token Currently, although its functionality is basic, it is the most widely used and most relevant standard due to its great interoperability in the environment. Provide the methods of token transfer (transfer), approval or authorization of use of your tokens to another Ethereum address (profit), authorized token transfer from another Ethereum address (transferFrom), current balance query (balanceOf), and query of the number of tokens possible to use on behalf of another Ethereum address (allowance). In addition, there are two types of events (Transfer and Approval) that are triggered when a transfer or approval is made. To characterize the token, a value must be assigned to a series of attributes in the form of a variable. The only mandatory parameter is the number of total available tokens (totalSupply), the others such as the name (name), the symbol (sym), and the number of decimals (decimals) are optional, although important if you want to give more detail to your token and distinguish it from others. The number of decimal places offers the ability to subdivide a token unit into 18 decimal places. But, where is the balance of each user who owns that token kept? Good question. To save the balances, a 'mapping' type variable is used, which relates an Ethereum address with its corresponding token balance: (mapping (Address => uint256) balances) In the 'Etherscan' explorer you can check the number of existing tokens deployed in the main Ethereum network, as well as their value and more information. At the time of writing this article, there were 125,699 ERC20 tokens. Probably when you look back at this number it has grown quite a bit, as new ones are being deployed every day. ERC-721 Token The ERC721 is the standard of NOT fungible token par excellence (called NFT, Non-Fungible Tokens). The concept of "NO fungibility" comes to say that it is unique and cannot be replaced by another. Another characteristic resulting from the above is its indivisibility, since it remains as a singular unit, unlike the ERC20. It is therefore a non-consumable token, but it is exchangeable. It can represent anything from ownership of a work of art to a loan or a traffic ticket. An example of a non-fungible token could be the owner of a house since it is something unique and indivisible that when you transfer it to another person it becomes part of their property and you would stop owning it. An example of a fungible token would be money, where a monetary unit (for example, a € 1 coin) is equal and has the same value as another monetary unit (another € 1 coin) Other possible implementations to carry out can be to reject transfers if the contract is paused, create a list of safe or authorized addresses, reject non-secure transfers, charge the cost of the transaction to both parties, etc. At the moment, its use is inferior to the ERC20, although it must be recognized that its future is very promising. In the 'Etherscan' explorer it can be seen that there are 262 ERC721 tokens deployed on the Ethereum mainnet. Token ERC-777 - New Advanced Token Standard It is an improvement of the ERC20 that incorporates more advanced functionalities such as: • Implement a send function: send (to, amount, data), instead of the usual transfer function: transfer (to, amount). • It allows to control and reject tokens sent/received by registering “hook” functions: tokensToSend (operator, from, to, amount, data, operator data), tokens received (operator, from, to, amount, data, operator data). It is useful, for example, to give the sender or recipient the option to intervene in the transfer and even reject it. Development of ERC20 that incorporates an exchange service facilitating cross payments of tokens. It allows the holder of an ERC20 token to exchange it with another ERC20 using an exchange token to make the transfers: exchange token (target contract, amount). It implements variables of type “mapping” to relate: address and amount of the exchanged token (exchanged with); address of the person initiating the exchange and the amount (exchanged); and the number of tokens received and the address of the person who issued it (exchanges received).

What are Ethereum ERC-20 tokens and why are they so useful? Ethereum is not just a type of cryptocurrency. It is the most popular engine that enables token creation. This development platform allows users to, for example, create DApps (decentralized applications) using smart contracts. It is also possible to devise tokens through smart contracts. Currently, Ethereum tokens have an implementation standard known as ERC-20 token (from Ethereum Request for Comments). Extensions to the standard are also developed, which improve the operation of the tokens: ERC-223 and ERC-721. Anyone who has been working on the topic of cryptocurrencies for some time has probably heard of the ERC-20 token. The ERC-20 implementation standard allows for uniform implementation of the functionality. Among other things, it offers advantages such as easier implementation by developers or the possibility of using tokens with third-party software. This is possible because the nomenclature is fixed and the developers simply know what to expect. What is ERC-20 Token? To put it in specialized terms, and in its simplest formulation, ERC-20 is a protocol that consists of a set of individual guidelines. With ERC-20 tokens are created on the Ethereum blockchain and use its technology. The main cryptocurrency based on the Ethereum network is Ether, but this does not mean that other tokens cannot exist in it. Thus, in simpler terms, ERC-20s are tokens that have been built on and use the Ethereum network. For this, a smart contract is essential. It is not only used to create tokens, but also to manage or monitor transactions. To receive the tokens in question, you have to spend a certain amount of ETH to the Smart Contract, in exchange for which the Smart Contract will send you these tokens. Thus, an ERC-20 token development can be done by any of us without having to be a programmer. You don't need specialized knowledge. You just have to use a smart contract to become the creator of your own token. It is important that you know that there are many more tokens than cryptocurrencies. A token is not always a cryptocurrency. These represent some fact, value, or quality. A token is often used, for example, in a casino as gift cards or vouchers. Why was such a unit of value created? Because the developers wanted to be able to manage the business model themselves. As a result, users on a given network are directly connected to its products. How do ERC-20 tokens work? ERC-20 tokens operate within the Ethereum blockchain. The ERC-20 token implementation is famous for the ability to independently create your own digital asset, as well as a smart contract. The process of bringing them to life is equipped with the ability to independently determine the maximum supply value, the possibility of divisibility of the new token, and basic information about the name or abbreviation of the newly created token. ERC-20 is a protocol that allows you to authorize the execution and execution of token transactions based on these principles, with the participation of third parties. An ERC-20 based token must define multiple functions. These include: Name. Symbol. Decimal places that determine the token's divisibility. The total amount of available tokens. The status in the indicated account and the function that allows you to make transactions. The ability to transfer tokens to other accounts through third parties, being able to consult and establish a maximum limit to the amount that a third party can manage. Of course, it should be noted that implementations of the ERC-20 interface may vary in detail. They can also be more elaborate, providing additional functionality (for example, such as freezing some funds, managing ETH transfers, or automatically granting tokens in exchange for cryptocurrencies). Depending on the goals of the creators, tokens created with the ERC-20 protocol can support security or put a strong emphasis on saving the gas consumption of the contract. Why were ERC-20 tokens created? There were many compatibility issues between the various forms of Ethereum tokens before the advent of the ERC-20 standard. Each token had only one smart contract. The platform had to write completely new code for every transaction and wallet in order to add a new token to its network. Maintaining a growing pool of tokens was becoming too troublesome and time-consuming. As a solution, the platform proposed a standard protocol for all the following tokens: ERC-20. The ERC-20 was created to make it easier for developers to create new tokens without having to start over every time. The ERC-20 protocol has functions that show how tokens can be transferred and how to access data related to tokens. The events, on the other hand, contain formatting guidelines for transfers and approvals. The ERC-20 token standard was introduced mainly due to the increased interest in ICOs. #erc20 token generator, erc20 token development company, ethereum token development

Cryptocurrency List: Discover 5 of the Top Digital Currencies! 1. Bitcoin Bitcoin is the best-known virtual currency. It was the first decentralized global payment system. This means that he is not directly linked to any country. Thus, the quotation is not subject to the laws of any specific government. Developed in 2008, bitcoin was the first major cryptocurrency released. It was aimed at replacing paper money and ending the need for the influence of banks to broker financial transactions. Bitcoin is mined and traded through technology. Currency transactions are recorded in a complex computer system called a blockchain. This system depends on several computers around the world to function. Mining (obtaining new currencies) and bitcoin transfers are recorded in the blockchain, which works like a ledger. It also ensures more security to operations, as it makes attacks by malicious people more difficult. Although bitcoin is an unbacked currency, it is increasingly accepted as a form of payment by companies and institutions around the world. For this reason, it remains one of the main cryptocurrencies on the market. 2. Ethereum There are some similarities and also differences between bitcoin and ethereum – which was originally called ether. However, in 2016, a hacker found a flaw in the cryptocurrency system. With that, he managed to steal the equivalent of $50 million worth of ether. This action caused several doubts about the future of the currency, so the community that maintained it decided to create another network. Thus, the original ether, which was the target of the robbery, came to be called ethereum classic. And the virtual currency that started to circulate in the new network was called ethereum. With the support of its community, it came to be worth more than the first version. Unlike bitcoin, ether was not created to be a digital currency. The goal was for it to become an asset to reward developers for their contributions to the Ehereum platform and their projects. Ethereum development is among the most traded virtual currencies in the world. The platform is decentralized and used to carry out smart contracts. That is, they are operations performed automatically when certain conditions are met. The blockchain is also the basis used for validating transactions with ethereum, ensuring security, and preventing fraud. As with bitcoin, the process of creating new cryptocurrencies is based on mining. 3. XRP Ripple was created in 2011 and is a distributed payment protocol. It has a currency native to its system, the XRP. The platform has the differential of supporting other tokens in its network, which can represent traditional currencies and other goods. The system seeks to allow secure and instant payments. In a way, Ripple is similar to banking institutions, as it accepts different assets and facilitates the execution of transactions. Thus, he moves away from the ideals of other cryptocurrencies. The speech aims to end the dependence on the traditional financial system to carry out transactions. Thus, the XRP virtual currency was conceived in 2012 by developer Ryan Fugger, programmer Jed McCaleb, and entrepreneur Chris Larsen. Most of the coins remain in their possession. Unlike other digital currencies such as bitcoin and ethereum, there is no mining process in Ripple. The system connects payment providers, banks, businesses, and digital asset exchanges to provide a frictionless experience and send money globally. 4. Litecoin Litecoin is a cryptocurrency created in 2011 by Charlie Lee – a former Google employee. The coin has many similar characteristics to bitcoin, but the main difference is in the mining process. The purpose of litecoin is to reduce the time it takes to confirm transactions made with the currency. The idea is to make it easier and simpler for anyone to participate in the process of developing new litecoins. Another intention of litecoin is to be a virtual currency accessible to the general population. To do this, Charlie Lee sold all his shares. Thus, he could not interfere with cryptocurrency prices. Due to the faster processing, litecoin is considered a more efficient alternative for carrying out day-to-day transactions. On the other hand, bitcoin is seen as a better source of the store of value. Also, litecoin was developed to produce more units. While bitcoin has a limit of 21 million coins, the limit for litecoin is 84 million. https://www.blockchainx.tech/erc20-token-development

12 Reasons to Invest in Ethereum 2021 Is it a good idea to invest in Ethereum? What does this cryptocurrency have that many see as the most powerful competitor to Bitcoin? Will it be able to surpass the crypto queen? Will it be a good investment? We will solve these and many other questions in this guide on this popular cryptocurrency. I anticipate that there are many who bet on this cryptocurrency but there are also many who say that it will not go too far. Of course, you will not think that everything is a bed of roses when it comes to investing in Ethereum. No investment is risk-free and neither is this currency. I'm going to cut to the chase and list the reasons why it is a good idea to invest in Ethereum and the reasons why it may not be such a good idea. Advantages and disadvantages of investing in Ethereum 1 It's more than a cryptocurrency Ethereum is not a cryptocurrency itself (Ether is the token that is used in it for exchanges), but a platform based on blockchain technology that allows to develop decentralized applications that use Blockchain in it, so its potential lies in its power as a kind of structure based on the programming of a possible virtual world. Bitcoin, on the other hand, is more of a pure currency. 2 Smart contracts It can be used to create Smart Contracts with which its potential is enormous. It seems increasingly clear that the future of crypto is going to be related to this type of contract. 3 He's behind DeFi This is one of the developments that are called to dominate the future of global finance and especially related to the virtual world. Many experts say that DeFi will eventually replace traditional centralized finance. At Harvard they are thinking that this may be the basis of future finances. 4 The NFT market depends on Ethereum Another of the trendy markets for cryptocurrencies and everything related to the Blockchain. Stories like those of cryptopunks and other platforms have meant that these tokens have risen to fame. These Non-Fungible Tokens that are based on smart contracts seem to be leading the way towards a new way of proving ownership of things, something that apparently can also be applied to physical goods, not just virtual ones. Why is Ethereum important here? Because a good part of the most important NFTs are built with the technology of this crypto. 5 The World Economic Forum bets on tokenization The controversial WEF has published that it is expected that by 2025-2027 10% of the world's GDP will be tokenized, that is, it works under blockchain technology transactions. And what is the most powerful blockchain technology in the token market? Ethereum. 6 It allows to diversify in cryptos Many investors are nervous about investing in only one or a few assets. Bitcoin is the cryptocurrency that attracts the most interest and investment, but many of the investors who enter this market look for other assets where they can maintain a more diversified profile. In crypto the best asset to get into after Bitcoin is the development of Ethereum, so any crypto portfolio that seeks to comply with this concept would do well to acquire this cryptocurrency in it. 7 It is a remedy against censorship As it is a decentralized technology on the Internet, it is capable of resisting censorship attempts by the authorities. For example, suppose a government wants to block access to a website in a country; something that is perfectly possible. What is not possible is that government eliminates a "transaction" recorded in the blockchain. In this way, a publication in the Ethereum system is recorded on a decentralized computer network to which the government has access. It is true that we can argue that the government can make it impossible for you to have a computer and therefore the above is of no use, but there we would already be in a more complicated form of dictatorship.
