Crypto Academy Season 2 Week 4 Homework Post for (@pelon53) - Tokens Part 2

This week, the professor examined the ERC-20 and ERC-771 standard tokens to the finest detail. He asked 3 questions for us to prepare homework. I read the professor's course article, started my research, and now I'm writing his homework.

P

ERC: means Ethereum Requests for Comments. They are technical documents created for decentralized applications (DApps) and smart contracts in the Ethereum network to interact with each other in an easier, faster and more efficient way.

TRC: We can say the same for TRC as we said for ERC. The only difference is with the ERC Ethereum network. TRC is related to the Tron network.

Token: In short, we can say that they are digital assets.

Explique en detalle el Token ERC-1155

There are many ERC type tokens on the Ethereum blockchain. These; Such as ERC-20, ERC-223, ERC-721, ERC-777, ERC-998, ERC-1155 ERC-1337, ERC-1400.

One of the ERC type tokens is ERC-1155. The ERC-1155 standard was created in 2018. Ethereum developers want to revolutionize the blockchain ecosystem. Ethereum developers are constantly working on issues that are lacking, inadequate, and solutions are not produced in the blockchain ecosystem.

The ERC-1155 standard is designed for the video game industry. Today, the number of game enthusiasts is quite high. For gamers, it was very important to create blockchain-based assets.

The ERC-1155 standard is called the Multi Token standard. This is because previously existing ERC standards are combined, comprehensive or created by adding new features.

It's pretty impressive when it comes to scalability. It has the ability to process a large number of transactions per transaction.

ERC-1155 standard provides convenience and practicality. Previously, we had to do a lot of processing to have a service. To purchase a service with ERC-1155, we only need to make a single transaction.

The difference between ERC-771 and ERC-1155 is this. The ERC-771 standard cannot be changed in any way. ERC-1155 tokens, on the other hand, are semi-exchangeable. The ERC-1155 standard can both create modifiable assets and create immutable assets. ERC-1155 is more extensive.

Example of ERC-1155 standard: Enjin

An example of an ERC-1155 based token is Enjin. Enjin is a project running on the Ethereum network. Apart from having an ERC-20 token, it also supports ERC-1155 smart contracts. As it is known, game lovers show a great interest in digital products used in game content. At this point, Enjin makes it easy for gamers to deliver digital products. They help those interested in games with practicality and reliability.

P

The digital currency of the Enjin blockchain is Enjin coin. Its current price is $ 2.68.
Market value: $ 2,247,372,710
Circulating Supply: 834,313,757 ENJ
Total Supply: 1,000,000,000 ENJ

Explain how you verify the amount of ERC-721 tokens existing at the time of doing your homework. Present screenshot (use etherscan)

The ERC-721 standard is a standard used for the creation of unique and unchangeable assets / tokens on the Ethereum blockchain. Another name is non-fungible token. It entered our lives in 2017. Especially this year they have become very popular. They have become the center of attention of investors.

We use https://etherscan.io/ to verify the ERC-721 token amount.

First, we click on the '' tokens '' tab on the top right, then click on the '' ERC721 top tokens '' tab.

As of now, 11,039 ERC-721 Token contract contracts have been found.

Explain the TRC20 Token and check the amount of TRC20 tokens existing at the time of doing your homework. Present screenshot (use tronscan)

The decentralized application is one of the TRC standard tokens created on the Tron network, which has the ability to create smart contracts. It is similar to ERC-20 tokens in the Ethereum network. It is fully compatible with ERC-20 tokens. WBTT, USDT, WIN TRC-20 are examples of tokens.

TRC's statement: Tron Requests Comments.

USDT, a dollar-pegged token, can be generated and transferred across many networks. There are also ERC-20 based USDTs, there are also TRC-20 based USDTs. However, transfers of USDTs produced on the Tron network are faster. Also, transfers are free. Therefore, tokens in the TRC-20 standard are costless and transfers faster than the tokens in the ERC-20 standard.

To create ERC-20 tokens, certain conditions must be met. In order to create TRC-20 tokens, it is necessary to organize according to the criteria. Some items are optional, while some items are required.

Token Name: The used name of the token.

Token Abbreviation: Token's symbol

Token Precision (Decimals): Indicates how many units the token will be split into.

Total Supply: Refers to the total coin supply.

Balance Of: Returns the token balance of any address.

Transfer: It functions as a transfer from any address to another address.

Approve: Authorize 3rd party applications.

Transfer From: It performs the transfer process of the 3rd party application between users.

Allowance: It is useful for querying the remaining balance for the 3rd party application to complete the transfer process between users.

Checking the amount of TRC-20 tokens available;

We log in to the website https://tronscan.org/#/. This website helps us access all the details with the Tron network.

First, we click on the "Tokens" tab in the upper left. Then we click on the "Token Tracker" tab.

Click on the "TRC20" tab to find the current TRC-20 token number. By clicking, we can learn that there are 15,797 tokens.

Conclusion:

In this lesson, I explained what the ERC-1155 token is, what it does, and how it differs from other ERC standard tokens.
I explained with screenshots what the ERC-721 standard tokens are and how the current ERC-721 token amount is verified.
What are TRC-20 tokens. I have specified the steps followed to create TRC-20 tokens.
