Geoblocks implemented by crypto services like cryptocurrency exchanges usually block the IP addresses of large collections of users from connecting to their websites or mobile applications. These blocks are accomplished by comparing a user's IP address to a list of allowed and not allowed IP addresses. IP addresses identify a person's location in the world, and crypto services can use that information to block specific locations by country, region, state, city, or even just an individual IP address
Example
“A trader in the U.S. was unable to access a DeFi protocol because the platform had implemented geoblocking to restrict access from jurisdictions with strict crypto regulations.”
