Digital preservationist, David Rosenthal, has a blog post discussing his recent Coalition for Networked Information (CNI) talk about distributed ledger technology. CNI is a joint initiative of the Association of Research Libraries (ARL) and EDUCAUSE to promote the use of digital information technologies to advance scholarship and education. The discrepancy between the available capacity in transactions per second and what is actually needed, plus the excessive power consumption, suggests that many attempted uses for distributed ledgers are inappropriate and counterproductive.
I gave a talk at the Fall CNI meeting entitled Blockchain: What's Not To Like? The abstract was:
We're in a period when blockchain or "Distributed Ledger Technology" is the Solution to Everything™, so it is inevitable that it will be proposed as the solution to the problems of academic communication and digital preservation. These proposals typically assume, despite the evidence, that real-world blockchain implementations actually deliver the theoretical attributes of decentralization, immutability, anonymity, security, scalability, sustainability, lack of trust, etc. The proposers appear to believe that Satoshi Nakamoto revealed the infallible Bitcoin protocol to the world on golden tablets; they typically don't appreciate or cite the nearly three decades of research and implementation that led up to it. This talk will discuss the mis-match between theory and practice in blockchain technology, and how it applies to various proposed applications of interest to the CNI audience.
Below the fold, an edited text of the talk with links to the sources, and much additional material. The colored boxes contain quotations that were on the slides but weren't spoken.

I think you're missing the sarcasm in:
Of course that's not what blockchain is designed to do, that's the widely acknowledged (often mistakenly discounted) weakness in the original bitcoin protocol.
Loosely equating blockchain and bitcoin is kind of like loosely equating Republicans with blind fundamentalist racist idiot bigots. Of course that's not true of all Republicans, just the entertaining ones.

I know you're being a little sarcastic there, but the shitty Republicans hurt my brain on a logical and moral level. Entertaining they are not, their rhetoric is so obvious and bad I can not call it entertainment. Their views quite literally impact the freedom and safety of their fellow citizens.
For a group that doesn't like being compared to Nazis they sure are quick to label any opposition as Pol Pot style socialists, as if no one has enough of a brain to see through that comparison.

The #AmazonWashingtonPost [twitter.com] says I'm the worst guy since Pol Pot (RIP!!!). Because I promised to get the 11 million Illegals out of our Country -- something I'm working very hardon (very successfull meeting with Chuck & Nancy). So I invited Henry Kissinger -- big Pol Pot guy -- to my Washington White House. Something Crooked H would have loved to do. She couldn't do it, because she lost very badly. And I had a great talk with Henry. We talked about North Korea, China and the Middle East. So interesting! And I'm thinking, maybe Pol Pot wasn't so bad. He's not my enemy!!!

Don't you and Chuck and Nancy all basically agree on the immigration issue?
Have you outdone the Deporter in Chief yet?
Only crazy libertarians and socialists believe that labor should be able to move as freely as capital moves.
