In reply to climbingkid:
The only constructive suggestion I can make is to use the UKC logbook facility. If the route / mountain isn’t on it, you can add it. Plus Facebook and Instagram.
An old lady used to record details of all Himalayan expeditions. Mostly of interest for statistical / historical purposes.
Obviously if an ascent is newsworthy, ie first ascent or rare repeat, it may well be mentioned in the climbing media.
Other than that, the climbing community doesn’t really do certificates. People tend to trust others to tell the truth when they claim to have done a route (although these days it would be rare not to have any photos etc if it’s anything significant). For the climbers themselves, a personal sense of achievement, (usually) happy memories and perhaps some photos and a log on UKC and/or social media tend to be sufficient.
Memory fades with time (well at least mine does), which is where photos, logs and social media posts come in handy, particularly at this difficult time when we can look back on past experiences and look forward to new ones.
