Q: Outside of IBC, are there any other promising cross-chain messaging standards that you are seeing? If so, why?

Polynya: I’m not an expert on bridges - IMO, only rollup bridges are good enough, so that’s all I know about. However, my semi-informed opinion is that more promising solutions than light client bridges are optimistic bridges and validity proof bridges. (see: Nomad; Ethereum <> Mina bridge by =nil;). These bridges verify full state transitions, so as long as you assume the weaker chain is not compromised, they are as good as rollup bridges. Of course, rollup bridges continue to work even if the weaker chain is compromised, and are as such the only acceptable solution. Once again, obviously all sorts of...
