How Chain Analytics Firms Build Their Labels

Much of what is known about who owns what on a blockchain is not read from the chain directly but supplied by a small industry that exists to label it. These firms turn anonymous addresses into named, categorised entities, and they sell the result.

Their method is patient aggregation. They cluster addresses that behave as one, attach labels from exchange data, leaks, public posts and their own research, and build a map that grows more confident with every transaction. An address unlabelled today may be named tomorrow.

Their customers are exchanges, banks, authorities and investigators. The labels feed compliance checks, freezes and investigations, which means a label, right or wrong, can have real consequences for the person behind the address.

What makes this matter to a private holder is that the labelling happens whether or not they are aware of it, and they rarely get to see or correct what is held. The map is built about them, not with them.

We understand how these firms reason, and read a client's exposure as they would, so the picture being assembled about them is known to them too, rather than only to those who buy it.
