ERC-20, BEP-20, TRC-20, WRC-20 standards
What is a network?

For the cryptosphere, the network is the blockchain. There are a large number of definitions that describe this technology in different ways. If we generalize as much as possible, a network is a digital space distributed between the nodes (nodes) of the network, which allows work to be carried out with maximum trust in data.
This space can be used for a variety of purposes: transactions, computation, data storage, etc.
For a long time the concept of decentralization was discussed by a small circle of cryptographers. In academic circles, there was active work on creating technologies that could make it a reality.
Very often technologies appear before a request from a mass user is created. The 2008 crisis and the response of central banks to issue new money made people think about the risks of excessive centralization of power.

In response, the first crypto-network, Bitcoin, was created with the task of creating a decentralized payment system.
The most popular Ethereum network
Bitcoin's popularity was actively growing, active users and enthusiasts began to think about wider application of the technology.

As noted above, the technology was first used to create a payment system, but Vitalik Buterin and his colleagues went further and proposed to create a network on which smart contracts (programs) could be run.
Explosive growth has begun, entailing the emergence of various crypto segments.

Development of the ERC-20 technical standard
There were more and more tokens on the Ethereum network, there was a compatibility issue as they used separate smart contracts.
To simplify the life of developers, the Ethereum team decided to unify the rules for token deployment. On November 19, 2015, Vitalik Buterin and Fabian Vogelsteller published the new ERC-20 standard.
This further enhanced the growth of the projects as they were able to simplify the development.
1275 core tokens created on the basis of the ERC-20 standard.

Since then, the market has continued to evolve, new approaches to working with tokens have emerged, which has led to the creation of new technical standards on the Ethereum network.
- ERC-721 is the father of the NFT. Any NFT is created using this standard.
- ERC-777 - allows you to create additional features on top of tokens. For example, increased confidentiality of transactions or disaster recovery to bail you out if you lose your private keys. Due to certain technical problems, it has not spread.
- ERC-1155 - allows for more efficient transfers by combining transactions, thereby reducing costs. It also allows combining NFT and interchangeable tokens as a single token.
- ERC-4626 is a tokenized storage standard designed to optimize and unify the technical parameters of revenue vaults in DeFi.
- And many others.

Why so many standards, you may ask. The field is constantly evolving, new ideas appear, which forces to come up with solutions for their realization. That is why new technical standards are constantly appearing to simplify the work.
Because of the basic limitations of the Ethereum network, many projects have released modified copies of Ethereum that solve these problems (scalability, speed). The token standards and operating principles remain the same, so Ethereum and the new systems are interconnected. The projects improved the disadvantages described above and also took advantages - developers, community, volumes and so on.
Technical Standard BEP-20
Supported by the BNB Chain network. The project followed the way of improving and optimizing the shortcomings of Ethereum. Cheap commissions, fast speed, simplified development environment. Unfortunately, we had to sacrifice decentralization.
BNB Chain leads in the number of active users among all networks, but lags behind Ethereum in terms of transaction volume, number of active developers and projects.
1208 core tokens created based on the BEP-20 standard out of 3.4 million tokens.

BNB Chain has also adopted many of the technical standards from the Ethereum network.
- BEP-20 is a tokenization standard in the BNB Chain network that extends the functionality of the ERC-20 standard.
- BEP-721 is the analog of ERC-721 and is used for NFT operations.

Technical Standard TRC-20
Supported by the Tron network. The project went the same way as BNB Chain - increasing the speed of transactions, making commissions cheaper. However, Tron failed to create a serious competitor for Ethereum or BNB Chain. The main use of this network is transfers of USDT token, which is actively used by users.
77710 tokens created based on the TRC-20 standard.

Powered by Ethereum, Tron has also adopted many technical standards.
TRC-10 is the underlying standard for Tron blockchain tokens.
TRC-20 is a standard used to create smart contracts.
TRC-721 is the standard for working with the NFT.
TRC-1155 - allows for more efficient transfers by aggregating transactions, thereby reducing costs.

WRC-20 Technical Standard
The WhiteBIT exchange is launching its WB Network blockchain to host both its own and third-party projects. It is currently undergoing testing, in which anyone can participate.
The active development and introduction of new services attracts a large number of users, which will ensure the adoption of the new ecosystem.
7478 test tokens created based on the WRC-20 standard.

The WB Network is likely to borrow the core technical standards of the Ethereum blockchain.
WRC-20 is a standard used to create smart contracts.
WRC-721 is the standard for dealing with the NFT.
