About this link preview
The Hashgraph Association (hashgraph.swiss) is filed under Business in the LinkPreview gallery. Its meta title is just 25 characters, well short of the 50–60 that usually show in full on Google, so there is room to add a keyword or a clearer promise. The description runs 167 characters, past 160, so the end will likely be cut off on Google. The Open Graph image is 1200 × 630 pixels, the standard size for X, LinkedIn, Slack and WhatsApp cards.
