By applying the Crystal of BitFury and leveraging ERC20 token transfer functions, it has opened up a new path for investors and the financial community. 70% of the revenue of the commissions generated from the Trading Platform will be paid daily to investors participating in entrustment to KFCE.<\/p>\n<p>KFC Exchange applies high technology to its trading methods as well as its platform. And we will learn about the technology applied in this exchange.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"ERC20_standard\"><\/span>ERC20 standard<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Firstly, ERC20 standard, like other token standards, only defines the interface \/ API of the smart contract, not the implementation.<\/p>\n<p>In smart contracts, code is organized into logical groups called functions. The smart contract interface is a description of what its functions should do and its implementation is the actual code of the functions.<\/p>\n<p>ERC20 token is a smart contract that respects ERC20 standard. In fact, it means that smart contract functions respect the interface defined in ERC20 standard.<\/p>\n<p>There is a group of functions that define smart contract metadata, such as:<\/p>\n<ul>\n<li>Name<\/li>\n<li>Symbols<\/li>\n<li>Decimal number<\/li>\n<\/ul>\n<p>The software of ERC20 standard is the account system. ERC20 ledger manages Ethereum addresses and token balances, just like the bank manages the account owner\u2019s ledger and identifier money balances.<\/p>\n<article class=\"text-token-text-primary w-full\" dir=\"auto\" data-testid=\"conversation-turn-4\" data-scroll-anchor=\"true\">\n<div class=\"text-base my-auto mx-auto py-5 [--thread-content-margin:--spacing(4)] @[37rem]:[--thread-content-margin:--spacing(6)] @[72rem]:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:32rem] @[34rem]:[--thread-content-max-width:40rem] @[64rem]:[--thread-content-max-width:48rem] mx-auto flex max-w-(--thread-content-max-width) flex-1 text-base gap-4 md:gap-5 lg:gap-6 group\/turn-messages focus-visible:outline-hidden\" tabindex=\"-1\">\n<div class=\"group\/conversation-turn relative flex w-full min-w-0 flex-col agent-turn\">\n<div class=\"relative flex-col gap-1 md:gap-3\">\n<div class=\"flex max-w-full flex-col grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"eec75f9b-b1e3-4a18-9313-c5f0b975328b\" data-message-model-slug=\"gpt-4o\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose dark:prose-invert w-full break-words light\">\n<h3 data-start=\"0\" data-end=\"37\"><span class=\"ez-toc-section\" id=\"ERC20_Token_Transfers_and_Delegation\"><\/span>ERC20: Token Transfers and Delegation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<p>In addition to storing the tokens, ERC20 tokens must also be able to transfer tokens. There are 2 functions in the ERC20 standards for that:<\/p>\n<ul>\n<li>Bank transfer<\/li>\n<li>Transfer from<\/li>\n<\/ul>\n<p>The first function allows the token owner (identified by someone\u2019s Ethereum address) to transfer the token to another Ethereum address. The cryptographic system of the Ethereum blockchain will ensure that the legal owner of the tokens has activated the function.<\/p>\n<p>The second function allows the third party\u2019s Ethereum address to carry out token transfers on behalf of the true owner of this currency. This is very similar to credit cards where merchants may be allowed to debit credit cards on behalf of their owners. The big difference is that in the case of ERC20 tokens, we only allow third parties to spend a specific number of tokens, but not large or unlimited amounts, as with credit cards.<\/p>\n<p>The entire third-party payment process consists of 2 steps:<\/p>\n<ul>\n<li>First, the token owner approves a third party to spend the token money on their behalf.<\/li>\n<li>After that, the approved third party can spend the maximum amount of this token. These tokens can be sent to any Ethereum address.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Crystal_of_Bitfury\"><\/span>Crystal of Bitfury<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Along with ERC20, Crystal of Bitfury is also used by KFCE.<\/p>\n<p data-pm-slice=\"1 1 []\">The Bitfury Group is the largest full-service blockchain technology company in the world.

The Bitfury Group believes it is incumbent on them to set a safe and responsible path forward for people who use this technology. By supporting secure protocols like ERC20 token transfer functions, the company helps ensure safer blockchain adoption. They always work to ensure that their reputation and that of blockchain companies\u2014especially KFCE\u2014is a top priority.<\/p>\n<p>Crystal of Bitfury analytics enhances due diligence and AML compliance procedures for organizations involved with cryptocurrency.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Comply_with_AMLCFT_regulations_when_dealing_with_cryptocurrencies\"><\/span>Comply with AML\/CFT regulations when dealing with cryptocurrencies<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Integrate Crystal analytics with existing AML\/CTF procedures and mitigate risks of dealing with blacklisted coins.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Build_automated_evidence-based_AML_procedures\"><\/span>Build automated, evidence-based AML procedures<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Improve your AML tools with Crystal blockchain and crypto-asset due diligence.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Keep_KFCE_data_secure\"><\/span>Keep KFCE data secure<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Deploy Crystal Pro in your corporate IT infrastructure to keep all sensitive data within the secure network perimeter.
