Abstract: Recently an idea for computing the entropy of black holes in the spin foamformalism has been introduced. Particularly complete calculations for the threedimensional euclidean BTZ black hole were done. The whole calculation is basedon observables living at the horizon of the black hole universe. Departing fromthis idea of observables living at the horizon, we now go further and computethe entropy of BTZ black hole in the spirit of statistical mechanics. Wecompare both calculations and show that they are very interrelated and equallyvalid. This latter behaviour is certainly due to the importance of theobservables.
