I`m curious about whether 28 era is a particular number, why not 26 or 27 or some else?

The unbonding period has to be longer than or equal to the grace period of slashes. Otherwise the nominator would be able to send their DOTs out and avoid them being slashed.

I believe that the 28 days-long grace period for slashes is to allow enough time for community discussion and to cancel the slashes in case they were unjustified

    also, 28 eras is relevant for long-range attacks.

  • thanks a lot for answering that question, it's helpful to know the number should be divisible by 7, meantime I just can't stop thinking about why is 28, and why other options like 35 days (5 weeks) are too long for that. Feb 16, 2023 at 10:12
