Data Brokerage

Data brokerage in the cryptocurrency context refers to the collection, aggregation, and sale of on-chain data to third parties, including governments, marketing firms, and security agencies. These brokers scrape public blockchain data and combine it with off-chain datasets to create comprehensive profiles of crypto users.

This information is highly valuable for tracking financial behavior and targeting advertising or law enforcement efforts. The commodification of this data creates a secondary market that operates largely outside the view of the average user.

It underscores the importance of minimizing one's digital footprint and using privacy-enhancing tools. As the industry grows, the ethics and legality of crypto data brokerage are becoming a major point of contention.
