Looks like a bug in how HN parses URLs. That's the URL I used but it seems like it was changed between when I pasted it and when it showed up.
It’s a probably bug on your website.
HN uses the canonical URL tag on the page linked by your post.
This is often misconfigured to point the root of the blog rather than the individual post.
It's not my website.
I wonder if you can have a full Mina node on any device including low-end phones, keep full network state and do payments in same time? It sounds too good to be true...
Highly unlikely. SNARKs have parameters that determine the probability of validating an incorrect proof and as the volume of transactions grows the probability that a node will accept an incorrect proof does as well. So as the network and transaction volumes grows the size of the proofs will also need to increase to remain within the tolerance level required to avoid validating incorrect proofs.
