With its proprietary blockchain platform, JD.com will distribute commemorative NFT certificates to attendees at the JDD 2021 event in Beijing, the new Chinese agency Sina Finance reported on Oct.

JD.com will specially give a free NFT to anyone who signs up for the JDD 2021 conference from October 18 through November 22 through the WeChat gadget on the event’s official website.

According to the report, the NFT series includes a number of seven NFT models, with each model containing different images that are used to identify different forums of JDD events.
