# GOAL:
|
|
# In this script I tried to implement the ECDSA signature using zenroom
|
|
|
|
# However, the scripts are customizable and so with the same procedure
|
|
# we can implement more complex smart contracts
|
|
|
|
# PUBLIC IDENTITY
|
|
# The public identity of the users in this script (Bob and Alice)
|
|
# is the pair (ECDH public key, Testnet address)
