I would like to use EOS to guarantee the integrity of my data stored in a database. Each time I save the data in BD I send the corresponding hash in the Blochain. My questions are as follows:

1- Is it possible to compare hash directly in the Blockchain using the smart contract? if yes how can we do it

2- How many nodes must I use at least to work well the network is what I must put them in a single PC or separate
