*Understanding blinded signatures and eCash Transactions *
Blinded signatures enable a privacy-preserving system where a user can receive transactions, such as tokens, without revealing their identity. In a fairground analogy, cash is exchanged for tokens that represent value and can be freely used for various activities without limits, ensuring quick and private transactions. The introduction of envelopes with unique identifiers allows users to request the desired amount while preserving anonymity, as the kiosk operator only verifies the official stamp on the returned notes and not the identity of the requester. This technique resolves privacy concerns linked to transactions, allowing users to maintain confidentiality from the initial cash exchange to the final redemption of tokens. The concept parallels digital cash systems like eCash, where the intuitive understanding of money as tangible notes contrasts with the complexities of blockchain technologies like Bitcoin, prompting a reevaluation of how digital currency functions and its privacy implications.
