What is blocks rewrite limit?

Hello,

What is the block rewrite limit(a maximum number of the blocks that can be rolled back) in Cardano? Or after how many blocks, blocks cannot be reversed?

I don’t know what a lower bound would be but Kraken.com uses 15 for their confirmations of Cardano. Usually exchanges go a little more extreme than necessary.

Ok. Thanks!
