I published my entry on the HIVE and STEEM blockchains instead of Medium.
The link for HIVE (via the Peakd front-end) is: NFTs: More than Games and Artwork | PeakD
The link for STEEM (via the SteemPeak front-end): NFTs: More than Games and Artwork | PeakD
Just to clear any possible confusion, these are blockchain blogging platforms, so other front ends (such as steemit and Hive.blog) will also display the same content. I will put a comment under the post to this link to prove ownership.
