I don´t see why you would decentralize such big house rentings system... Servers and databases will still do it much faster...
If ETH Network got a bit bottleneck for a simple kitties website.. could you imagine how it would be for a monster like airbnb ?
Idiotic is that there are so many platforms, but everyone builds on Etehreum altho they know in advance that all projects will have huge problems exotically beacuse there will be to many on Ethereum. Ethereum Blockchain will hit 1 Tb next year. I just dont understand this guys why they do it.
