Ecash TIDES using Cashu and Stratum v2

The discussion emphasizes the critical nature of prompt redemption by the receiver to mitigate the risk of a sender attempting to double spend in the context of electronic cash (ecash) transactions. It highlights that during such transactions, the sender shares the root secret associated with the blinded signature, necessitating the receiver to act swiftly to redeem the value, even though these transfers can occur offline.

Furthermore, an important aspect mentioned is the share window concept introduced in the TIDES documentation. This concept pertains to the necessity for a constantly updating list of electronic hashes (ehash) that must be monitored by the pool. This mechanism ensures the integrity and tracking of transactions within the system, providing a safeguard against potential fraud or duplication by keeping an ongoing record of all ehashes in circulation.
