Achievement NFTs: why blockchain makes sense for cyclists

A sticker inside an app disappears if the company shuts down or resets its database. An achievement NFT issued on a public chain keeps existing and remains verifiable regardless of whether Carbona keeps operating — ownership belongs to the cyclist, not the platform.

That changes how long-term achievements (like total distance ridden or accumulated CO₂) are treated: they become an asset the cyclist can display, transfer, or even sell — not just a number on a profile.
