Thanks for your contribution. Cardano has this limit: the protocol has maximum parameters per block, it admits up to 65,536 bytes per block, or 64 Kb (1024 bytes = Kb), that is to say that no more tx can be validated than this total weight in each one. Each tx cannot weigh more than 16,384 (16 Kb). The header of each block has a maximum of 1,100 bytes (1.07 Kb).
