A single transaction can create multiple outputs, as would be the case when sending to multiple addresses, but each output of a particular transaction can only be used as an input once in the block chain. Must be strictly greater than the median time of the previous 11 blocks. If the five transactions in this block were all at the maximum size, downloading the entire block would require over , bytes�but downloading three hashes plus the block header requires only bytes. Costs can rack up per terabyte on the chain per transaction, with fees each time you want to read that data.
