SEEDCARD project introduces a new approach to creating Bitcoin keys for physical bitcoin cards.
The project is still in the pre-development stage.
The main concern is to understand if ECC (elliptic curve cryptography) can be used to add private and public partial keys, generated on separate devices.
A user received an email explaining that it is possible to combine two private keys and get the same result as adding their respective public keys, enabling the generation of a full public key.
