ELI5: the human genome is fully mapped, but who’s genome is this?

There are differences between everyone’s genome, so when the human genome was mapped, who were they basing it off of?

Research shows that that the DNA of human beings is 99.9 percent alike. That being said, for the genome project scientists used DNA from five individuals of varying ethnicity. The five people whose genomes were used in sequencing came from a pool of 21 donors. It was agreed that donors names would never be made public. So we never will really know the identity of the DNA used.
