While blockchain is known for its ability to provide secure and immutable digital ledgers, it is also possible to trace transactions within a blockchain using sophisticated data analysis techniques.
In the case of public blockchains such as Bitcoin, the pseudonymous nature of the ledger makes it difficult to trace users without some additional information or metadata.If a user’s identity can be linked to one or more addresses on the blockchain, however, then it may be possible to trace their transactions across multiple blocks.
