Today's post is more about marketing the idea of blockchain. The word sounds intimidating to many people. That's probably because attempts to explain it often make use of a highly technical trade language that few people understand. My goal here is to think of ways to communicate the idea of blockchain in a manner that will make people feel like the concept is familiar to them. Indeed, I believe that the broad conceptual idea of blockchain should be familiar to us all.
Renowned Bitcoin expert Andreas Antonopoulos writes here:It will take time for the idea of decentralized trust through computation to become a part of mainstream consciousness, and until then, the idea creates cognitive dissonance for those accustomed to centralized trust systems. With thousands of years of practical use, centralized systems of trust are accepted unconditionally and without much thought as the only model of trust.
It's an excellent article and I highly recommend you read it. What I want to do here is push back a little on the notion that decentralized trust systems should necessarily create cognitive dissonance. In particular, I should like to point out that we've had tens of thousands of years of experience with decentralized trust systems. Alright, so let's get started.….Very worthwhile read if you don't know much about blockchain already. It's a simple explanation that David Graeber might have written. It's basically how decentralized systems based on mutual trust work and have since prehistory, and how digital networking allows this to be scaled.
Notice how the blockchain described above could serve a very useful economic purpose. In particular, notice that the act of consumption (medical services) in [1], John is effectively using [2] as currency. At least, this is how things work in what anthropologists describe as "gift-giving societies." And if you think about it for a while, you'll notice that the same principle is at work in the various groups you interact with on a daily basis (your friends, your family, coworkers, etc.). Much, quite possibly most, economic exchange occurs via such localized trust networks.
The problem with this ancient blockchain technology is that it doesn't scale very well. There's only so much data we can fit in our brains. So as populations grew and as people started forming large communities, a new type of record-keeping system was needed. The model that came to dominate is one in which databases are collected and maintained by trusted third parties. Much effort is expended in keeping these private databases secure (not always successfully). It is often difficult for these agencies to communicate and reconcile their databases (as in when you try to send money from your bank account to your friend's foreign bank account overseas).
And so enter the "new" technology, blockchain. I hope I have convinced you what is new here is not the principle of the blockchain. The new technological developments are: [1] bigger brains (increased capacity for data storage and processing via computers); [2] better communications (the Internet); and [3] computer-based algorithms to serve as communal consensus mechanisms (e.g., proof-of-work).
These innovations will permit a revolution in the truest sense of the word: we are traveling back to where we began--but with planet earth as our village.
