The better question is whether blockchain is worth implementing 
in D? ;) It wastes a ton of energy with the most common 
proof-of-work approach and, as I've pointed out here before, 
there are better ways to do it:

But some decentralized approach, if not blockchain, is 
undoubtedly going to be a huge winner, and of course D would be a 
great language with which to build it.  The lead developer of 
Bitcoin Cash, currently the fourth-most valuable cryptocurrency 
(https://coinmarketcap.com), gave a talk on doing crypto in D at 
the last DConf:

I don't think he's using D since they forked the Bitcoin source 
though.
