Transaction fees. 3.1. Alice has a large number of coins each of small value v , which she would like to combine into one coin. She constructs a transaction to do this, but finds that the transaction fee shed have to spend equals the sum of her coin values. Based on this information (and the default transaction fee policy specified in slide 50), estimate v . 3.2. Can Alice somehow consolidate her coins without incurring any transaction fee under the default policy? 3.3. Compared to a fee structure that doesnt factor the age of the inputs into the transaction fee, what effect might the current default fee structure have on the behavior of users and services?
