Not really, it is pretty much the other way around. :-) We're basically building the simplest thing that could possibly work, they are rebuilding a lot of infrastructure that they have to use, but we can use where it makes sense. So, they are kinda trying to implement the Web, which is a much bigger task than adding access control and identity... :-) There's also been quite a lot of overlap between people working on Solid and working on Blockchains in the past, so we know it well. But we're not really in competition, we'd be fine coexisting.
