1. I send you BTC using address for which I have a private key
2. I sign message by Crypti team using private key and reedem Crypti coins to address X
3. I complain to you that I have not received my Crypti coins to address Y
1. I send you BTC using address for which I have a private key
2. I sign message by Crypti team using private key and reedem Crypti coins to address X
3. Crypti team instead reedem coins to address Z
In above cases, you have no way to prove that either me or Crypti team cheated.
Just what? How do you do step 2?
1. You sign a message using your donation BTC address's PK that contains your Crypti address.
2. Crypti confirms the signature and sends CRY to that address
3. The Crypti is sent to that address
4. It is provable in the Crypti blockchain.
