Also:
1. steal n coins from Bob
2. steal n coins from Alice
3. move these 2*n coins to the same addresse.
4. give n coins to Charlie: these are stolen from both Alice and Bob.
5. the remaining n coins are clean.
- rocqua 9y agoNope, after step 3, the first 2*n coins coming out of that address are tainted.
- ogoffart 9y agoOnly if they are tainted with the same "tag". What if one of the theft is only recognized in one jurisdiction? What if Alice and Bob separatly track their coins?
- rocqua 9y agoSo, say Alice her money was transferred first, and bob's money second. Then, after you've spend N coins, anyone looking for bob's coins sees you no longer have them. Anyone looking for Alice's coins sees they are still with you. This is because it is FIFO, so the outgoing transaction is only spending from Bob's coins.
