With the efforts of our engineers and Parity developers, we brainstormed further on the best solution. Our initial thought was that a governance proposal was inevitable, as the header was now incorrect on Kusama and would conflict between our collators and Kusama’s validators. On the contrary, thanks to Basti, we figured this was not necessary. The system does not use the para_id in the genesis header. As we controlled the collators, we had to revert the para_id change to start producing blocks again. Definitely, a new discovery for our team, as it implies that the para_id in the genesis header is not used by the system everywhere. We have planned out for Q1 2022 to change this, and as far as we know, this does not pose any security challenge.
