Blockchain anonymity is a characteristic of certain blockchain networks that obscures the identities of participants. While all transactions on a blockchain are publicly recorded, pseudonymous addresses are used instead of personal information. This means that, although the transaction history is transparent and accessible, the identities of the parties involved remain hidden unless additional information is matched with the blockchain data. Several blockchain technologies, such as Monero and Zcash, use advanced cryptographic techniques to enhance anonymity, including stealth addresses and zk-SNARKs, making it increasingly difficult to link transactions to individuals.
