decentralized operating system supporting industrial-scale decentralized

applications is the aim of the EOS blockchain. One of the common roles of

tokens within the ecosystem, which can help create an internal economic

system within the application, is a value exchange. The User Experience

(UX) enhancement enables its holders to enrich the U X inside the confines

of the particular environment. An example of this and holders of BAT is

Brave (a Web browser). The tokens used in Brave obtain the rights to enrich

the customer experience by using their tokens to add advertisements or

other attention-based services on the Brave platform. As a currency, it can

be used as a store of value for conducting transactions both inside and

outside the given ecosystem.

ERC-20

A technical standard on the Ethereum blockchain used in smart contracts

for implementing tokens is ERC-20, and a maj ority of tokens are issued on

the Ethereum blockchain are ERC-20 compliant. For issuing tokens on

Ethereum’s network, it is a protocol standard defining the rules and

standards. ERC is the abbreviation for Ethereum Request for Comments,

and the number 20 in ERC-20 stands for a unique ID number to distinguish

this standard from others; it is a guide to the rules and regulations that help

in creating a model for Ethereum-based smart contracts to create their

tokens. A smart contract that follows some common rules like

implementing a standard set of functions that all other token contracts share

is a token, keeping track of who owns how much of that token, and some

functions so those users can transfer their tokens to other addresses. The

Ethereum blockchain enables the use of tokens that can be bought, sold, and

traded by its users; digital assets or programs are based on the blockchain

tokens. The purpose of attributing a value to them, such as promissory

notes, profit participation rights, services, or real obj ects, is served by these

tokens.

Rules for ERC-20 Token

The mandatory and optional rules that ERC-20 tokens follow so that they

can be shared, exchanged for other tokens, or transferred to a crypto-wallet

are:
