A whitelist is a list of addresses or entities that have been pre-approved to participate in a specific blockchain or cryptocurrency project. These addresses or entities have been vetted and deemed trustworthy by the project’s developers or community. The whitelist is often used to limit participation in a project to a specific group of people or organizations.
A whitelist is important for several reasons. First, it helps to prevent fraud and scams by limiting participation in a project to trusted individuals or organizations. Second, it can help to ensure that the project is not overwhelmed with too many participants, which can lead to network congestion and other issues. Finally, it can help to ensure that the project is able to achieve its goals by limiting participation to those who are most likely to contribute to its success.
A blacklist is a list of addresses or entities that have been banned from participating in a specific blockchain or cryptocurrency project. This can be due to fraudulent or malicious activity, or simply because the project’s developers or community do not trust them. While a blacklist is designed to prevent bad actors from participating in a project, a whitelist is designed to ensure that only trusted individuals or organizations are able to participate.
Many blockchain and cryptocurrency projects use whitelists to limit participation in their projects. For example, the popular decentralized finance (DeFi) project, Uniswap, uses a whitelist for its governance token, UNI. To participate in the UNI governance process, users must be on the whitelist. Similarly, the blockchain project, Polkadot, uses a whitelist for its parachain auctions, which allows projects to connect to the Polkadot network.
