* @brief Specification for a /deposit operation. The combination of
|
||||
* the coin's public key, the merchant's public key and the
|
||||
* transaction ID must be unique. While a coin can (theoretically) be
|
||||
* deposited at the same merchant twice (with partial spending), the
|
||||
* merchant must either use a different public key or a different
|
||||
* transaction ID for the two transactions. The same coin must not
|
||||
* be used twice at the same merchant for the same transaction
|
||||
* (as determined by transaction ID). (Note: we might want to
|
||||
* fix #3819 and include at least h_contract as well.)
