That is the blockchain’s greatest strength: that it’s designed to survive when people are unreliable. Whether that failing is business-, ethics- or technology-related, the blockchain can survive.
But longevity isn’t the only thing that a non-repudiation service needs. While it’s a critical problem to solve, it’s far from the most important.
In the U.S., the usefulness of a third-party, non-repudiation service, blockchain or otherwise, is limited by the U.S. Copyright Office. In short, anyone who is serious enough about their copyright to consider filing a lawsuit needs an official registration just to get into court and they need a timely one if they’re to collect all of the desired damages.
Since U.S. Copyright Office registration serves as prima facie proof of ownership, in most cases, a third-party service is superfluous from a content protection standpoint.
While non-repudiation services can provide a public record of ownership and a means to track a work back to it’s author, something the U.S. Copyright Office can’t do as effectively, that capability relies upon people being aware of the database and knowing how to search within it.
More importantly, copyright is governed by a patchwork of local laws that differ in sometimes important ways.
In an article about Binded's ability to protect creator copyright’s, author Nate Hoffelder maintains that companies like it are still selling the illusion of protection. While companies like Binded aim to help establish a date of creation for copyright works, that is almost never the issue. The underlying and real problem is ostensibly having any ability to remove or act on offending content or intellectual property and that will still require legal intervention.
The bottom line is that these innovators are truly making the problem hot again and directing more attention to it, as signified by Spotify’s recent acqui-hire of Mediachain. More attention to a problem always means more money and time dedicated to solving it. More money and time will mean more potential solutions and more stakeholder buy-in. None of that is trivial.
