Whitelist as a term has various meanings. In the blockchain and cryptocurrency space, a whitelist is a term associated with Initial Coin Offering (ICO) events, or withdrawal addresses for exchanges.
With regards to an ICO event, a whitelist is a list of registered and approved participants that are given exclusive access to contribute to an ICO or a pre-sale. A form is usually distributed to limited individuals to collect a list of emails of potential investors for an ICO,
Some cryptocurrency projects may offer a whitelisting phase for investors that are interested in taking part in the public sale of their tokens. Such Crypto project owners make use of the whitelisting process to enable them to verify potential token buyers and ensure they are compliant with the terms of the token sale.
For many ICOs that are done on Ethereum, the smart contract that governs distribution of the coins will only allow a ‘whitelisted’ person to participate and be allowed to receive tokens.
Whitelisting is similar to pre-registering for a product launch (think about signing up for the new iPhone or a sneaker launch) where potential buyers can indicate their interest in a company’s new product. When new projects are launched, verified whitelisted users will be allowed to take part in the initial sale of the token. Other investors will still be able to buy such coin later once the official sale begins, but they may buy it at a higher price.
In regards to withdrawal addresses, a whitelist refers to a list of cryptocurrency addresses that users consider credible to transact with. In that case, they would only be able to withdraw funds from their exchange account to the addresses that are already whitelisted. Only addresses that appear on such lists can withdraw funds from exchange accounts.
