Whitelist refers to a list of individuals, organizations, computer programs, or cryptocurrency addresses that have passed a particular approval process and will contribute to a specific event, such as an initial coin offering (ICO) or a presale.

Whitelist is a list created by companies, platforms or networks for various purposes, by adding a certain number of users. In the crypto ecosystem, it is usually created before ICO processes and grants users on the list to be informed early and participate in the pre-sale process at a lower price.

Basically, a whitelist is divided into types such as;

• Email whitelists,
• Advertising whitelists,
• Network whitelists,
• Crypto whitelists.

An email whitelist is an approved list of senders that is intended to prevent spam filters and/or emails from being sent to the spam folder. In this regard, predetermined sender IP addresses, email addresses, or domains are included in the whitelist to prevent such a problem. In this method, which aims to enable companies to communicate with their customers more securely and smoothly, if there is any complaint, the relevant company's whitelist operator also has the right to remove a server from the list.

As is known, advertisements, which are one of the important sources of income for websites, can be easily blocked by some applications used. Some companies that detect these ad-blocking applications activate the advertising whitelist and add their own websites to the whitelist, so that their ads continue to appear even if the user is using an ad-blocker.

Another type of whitelist, network whitelist, is one of the methods used to control the accessed networks. Network whitelist can also be divided into LAN whitelists, firewall whitelists, and application whitelists.

What Is Whitelist in the Cryptocurrency Ecosystem?

In the cryptocurrency world, the term whitelist refers to a list of approved participants, individuals, institutions, computer programs, or cryptocurrency addresses who have contributed to a certain event such as Initial Coin Offerings (ICO) or presales.

Whitelist allows access to an event for participants who have met certain requirements and have certain qualifications.

What Happens When You Are Whitelisted?

When you are whitelisted, you have priority access to an Initial Exchange Offering (IEO), an Initial DEX Offering (IDO), or a pre-sale of a cryptocurrency and as a result, it gives you a more advantageous position in terms of cost.

The whitelisted process includes providing personal information such as your name, email address, and necessary identification. Completing these steps to verify your identity is essential. Then it is determined whether you are eligible for the sale in question, so you become ready to be whitelisted.

After being whitelisted, you will receive an email with detailed instructions on the steps to follow during the initial sale.

What Is the Difference Between Whitelist and Blacklist?

Unlike whitelists, a blacklist is a list that includes users or wallets whose access to the platform is restricted.

Whitelists or blacklists created according to the commercial needs of companies can provide many advantages when used for their purpose.

For example, users who are identified as a threat to the platform's security or who do not comply with usage terms are added to the blacklist and blocked. This minimizes the potential dangers that companies or networks may face in the future.

Also, blacklists can be data-based, IP-based, or URL-based.
