A whitelist is a database containing a set of names that are verified and considered trustworthy by a group or an authority. In general, a whitelist may include IP addresses, e-mails, domains or telephone numbers. It is a tool mainly used in the cybersecurity field.
Whitelisting can also be used for email marketing, i.e. the sending of promotions or communications through the use of email, and in the management of computer software.
In the world of cryptocurrencies, the whitelist can be used to indicate all addresses to which it is safe to send withdrawals or transactions, or to grant selected users early access to NFTs (acronym for Non-Fungible Token) collections or ICOs (Initial Coin Offerings).
An NFT whitelist is a database of users whose wallet address has been verified and approved by the creator of the NFT collection. Generally used for the launch of a new NFT initiative, the whitelist allows supporters of a project to have early access to digital works or to receive exclusive content, without having to deal with competitors. The further in advance someone is of other interested buyers, the greater the likelihood that they have access to rare NFTs.
Whitelists also allows project creators to bond with their community by rewarding the most active users.
An ICO, i.e. the funding of a crypto project prior to its actual launch, can also involve a whitelist. Users registered in an ICO whitelist are guaranteed to participate in the ICO and are generally given the opportunity to purchase tokens related to the project in advance of the general public.
Becoming part of a whitelist requires significant research work, focusing on emerging crypto projects. Once an ICO or NFT initiative has been identified, it is important to interact with the relevant community by accessing the social channels shared by the project creator.
Each initiative has its own rules for inclusion on the whitelist: in some cases it will be sufficient to share the required information, in others active participation in the community will be rewarded.
In general, each user must implement protective measures to avoid running into scams or frauds that may hide behind fake ICOs or NFTs.
