Do you expect to see this patent apply to Bitcoin, or will developers come up with a different solution?
Patents are not something native to the Bitcoin world, but that isn’t keeping companies from trying to file them anyway. Bank of America has been trying to patent various blockchain-based solutions in the recent months, and now Verisign is looking to do the same. Based on a recent Medium post, we can see how Verisign wants to address the double spend scenario in the digital currency world.
