Blockchain is one part of a series of interlocking pieces that are attempting to democratize core parts of our society.
Namely those pieces are blockchain, proof of work, and a system of rules that encourages competitive enforcement of the networks rules.
So to pick off the blockchain, it's a cryptographically secured record of every transaction that has ever occurred on the network. If the rules are properly enforced, nobody can unilaterally steal your ownership of the assets it secures. Nobody can shut down your account. Nobody can silence you. You see a lot of tepid development for a lot of blockchain based commerce, dns, etc. Basically lots of areas where regulatory capture has resulted in a small number of duopolies. Duopolies increasingly flexing their muscle, to all our detriment.
I keep saying "If the rules are properly enforced", and that is where proof of work and competition come in. How do you keep the rules of the network properly enforced? Well, you reward people for doing it. With Bitcoin, if you add a block to the blockchain, you get rewarded in more Bitcoin. But you don't want this happening whenever someone feels like. So you have the proof of work. It's arbitrary, but it slows things down, and forces participants to put their money where their mouth is. If you take all this time, equipment, and electricity successfully completing a proof of work, and then you do something fishy, the rest of the network will reject the block you attempted to add to the chain and you get nothing.
Now, there are certain downsides we're all living with here. The competition to add blocks to the chain has gotten a bit out of control, and is sucking all the air out of the room. Outside of speculative investing, the use cases for crypto assets has come up significantly short. I'd love to see blockchain secured DNS take off, like Namecoin. But it hasn't done shit. The current, centralized, monopolized systems we have for money and information infrastructure are still mostly preferable to most people. Even with massive censorship and massive observable inflation. Normies just go along to get along.
I'm not sure how this ends. I don't know if stable, useful blockchain technologies ever take off. I don't know if they always lurk in the background, keeping the monopolies they seek to replace honest. Or at least slightly more honest than they'd otherwise be. I don't know they'll vanish completely. The cynical part of me says regulatory capture manages to subvert them, and chain them to the same institutions they were supposed to free us from.
The value of bitcoin aside, we'd probably all be a lot better off if our fundamental human rights were secured through a series of blockchain technologies than resting in the hands of SV to allow us to speak, Mastercard to allow us to conduct commerce, and Bank of America to not place bullshit liens on our properties to attempt to fraudulently steal our homes. But it could still be that the negatives of blockchain (consumption of resources) outweighs the benefits too much for it to ever really happen at scale.
