Parallel Vote Tabulation
A random sample, sealed
Before election day we draw a random sample of polling units and publish only its fingerprint. Nobody can know which units are in it.
Observers report
Trained observers photograph the result at each sampled unit.
Estimate and check
The sample gives each party's share with a margin of error. We compare it with INEC's declared result, then reveal the seed so anyone can re-draw the sample.
