Wow, this is beautifully done.
The site mentions the decryption key is released when the note is "cut". Does that mean there's something enclosed in the bill, and you have to physically cut it open to extract it?
- throwaway4aday 4y agoI'm guessing it means you need to destroy the note in order to redeem it which makes sense as a way of remotely "redeeming" the note with the issuer. I'm interested in how secure this process is since the entire system would hinge on it.
- ccamrobertson 4y agoThank you -- then chip has a tamper trace that needs to be cut (you cut roughly 1/4 of the note to slice it). Once the trace is cut the app can report that fact to us at which point we release the decryption key.
