Nah, BLIK from Poland was there earlier and is in many ways better, Wero was unfairly lobbied for by the old European guard, so most of Eastern Europe walked away.
They are now hesitantly joining Wero, supporting it only to downplay and to lobby ECB for an API platform and not for a product.
I've used BLIK once, for an online payment from the Netherlands to Poland, and for that it was terrible. I assume it's much better integrated into the Polish system.

BLIK was launched in 2015 according to Wikipedia; iDeal is from 2005.
