Micropayments on the blockchain can be revolutionary in two ways. The first is that donation recipients can easily set up accounts to receive funds, which will allow donations to be made directly to them, reducing all intermediary and administrative fees.
Fraudsters can also easily set up fake accounts to lure donors. Ratings and audits will be required, similar to current online services that rate charities based on multiple criteria (e.g. Charity Navigator, Smart Giving, Nonprofit Council, etc.) to ensure and provide better visibility for donors .
