We will setup a blockchain with off-chain data and currency coin for a Storage service.
The blockchain-parameters are:
Our questions are:
1. We want normal transaction is free, but off-chain transactions need to pay. The parameter 'minimum-relay-fee=0' is OK?
2. There are two nodes, one is storage node and another is miner node. I put 1Mb file as off-chain data one the storage node ,and pay 1000 * minimum-offchain-fee = 100 currency coins. Who will charge the 100 currency coins ? the storage node or the miner node?
