NFT's and Blockchain for Engineering

Upcoming community pieces that look to be of interest, join in.  Below just an intro, click through for registration and more detail.  If I can I plan to.

Does the engineering world need to care about NFTs and blockchain?  in Venturebeat.

If the first question out of people’s mouths about either blockchain or NFTs is “What exactly are they?” the second question inevitably is “Is this something that I actually need to care about?”

If you’re an artist who makes a living selling art, the answer might be yes. But if you’re in the engineering world, the potential benefits are far less clear.

If you’re an artist, you can see where this might be useful: You can put your art up for sale, and a collector can purchase an NFT that says that they are the official owner of that piece of artwork. (In theory, anyway – more on this in a bit.)

So, how might this apply to the engineering software space?     ‘I did that’

Unlike the individuals in the art world, people in the engineering world don’t generally create 2D files and 3D files just for the purpose of artistic expression and then try to sell them. They’re creating these assets because they intend to do something with those files, like designing and manufacturing an actual real-world object.

So, strike one: not much utility to be found for NFTs and blockchain on that particular front. But maybe there’s some other application in the engineering space, perhaps around intellectual property and documentation of the product development process?

Picture a manufacturer that is designing an innovative new bicycle. One engineer is in charge of the bike frame. As they go through the development process, each time they make a new CAD file, they check it into the blockchain so that their work on this new product is documented on the blockchain. Years down the line, if they need to prove their work on this product for some reason, a permanent, publicly available record is there for all to see, and the engineer can say “I did that.”

It sounds like a nifty use case. But alas, here is where the “theoretical” benefits of blockchain quickly run into some buzzsaws.     Not so fast…

For starters, while there are a small handful of companies making technology that does this type of thing, they are few and far between. In terms of the innovation-adoption curve, this field is really still in its infancy – which is surprising since the underlying tech has been around for almost 15 years.

That’s not to say that there aren’t plenty of enthusiastic voices out there around the potential of blockchain and NFTs in the engineering world – but not all of them have saintly motives. If someone has purchased a boatload of Bitcoin or NFTs for purely speculative reasons, they’re likely to champion anything having to do with blockchain and its potential because it indirectly benefits the investments they’ve already made.

Then there’s the matter of blockchain’s environmental impact. Even the newer, more evolved blockchain protocols like Ethereum still consume gargantuan amounts of energy [subscription required] as they record and validate transactions across a distributed and decentralized ledger. With the “proof of stake” mechanism for validating entries, this energy usage is less of a problem, although it has other issues. The bottom line, however, is that, on a fast-warming planet [subscription required] staring down a climate emergency, blockchain is a hard technology to embrace unless transactions can be made radically more efficient.

All of this is to say nothing of the fact that much of what blockchain could enable the engineering space to do is already possible to do – and much more easily accomplished – via existing methods. Want to show proof of prior work on a product? Any time you check your CAD file into some kind of CAD or PLM system, there’s an audit trail of who accessed, created or modified the file. Need an indisputable patent? There’s a patent office that decides those types of things.

While it might be nice to get an “official” NFT saying that the work in a CAD file is officially yours, that NFT doesn’t mean you own it in any legal sense. It’s just a digital signature that means something in “the world of blockchain” but doesn’t necessarily mean something legally. ....  '
