Transaction too large #28

Open cryptozeny opened 4 years ago

cryptozeny commented 4 years ago 
    // Extremely large transactions with lots of inputs can cost the network
    // almost as much to process as they cost the sender in fees, because
    // computing signature hashes is O(ninputs*txsize). Limiting transactions
    // to MAX_STANDARD_TX_WEIGHT mitigates CPU exhaustion attacks.

Workaround image

rakutens: Transaction too large is not very serious in sugar, because transfer records can be selected from wallet
