Look...It's easy to make fun of blockchains...

Step 1: You have a problem Step 2: You introduce a blockchain to solve problem Step 3: You now have an incentives problem, a trust distribution problem, a community management problem, a regulation problem, a speculation problem, an upgrade path problem...

What did one blockchain say to the other? . . . . . Hey you wanna fork hard?

Blockchains convert the problem of <trusting a centralized body with maintaining system state> to the problem of <trusting a centralized body to maintain code to maintain system state>.

The IOTA people are very clear that their system is not a blockchain, which is very fair, blockchains actually work in an adversarial environment.

You can generally split blockchains into 2 camps...and then 4 camps...and then 8 camps...and then 16 camps....

Some people think that blockchains are a hugely inefficient waste of precious energy resources, and other people have an incorrect opinion.

[Since some people are already being a tiny bit complainy in my mentions here is a thread explaining my blockchain opinions in a more nuanced and serious way, because jokes on the internet are hard. https://twitter.com/SarahJamieLewis/status/971482061520257024 … ]

Things were much easier in 1990: Step 1: You have a problem Step 2: Yo, I'll solve it Step 3: Check out the hook while my DJ revolves it (And yet, this approach makes possibly more sense than many proposed blockchain solutions I have seen.)

People just don't have the time to stop, collaborate and listen

Guess its cause Blockchains here and everyone thinks its a brand new invention!

Something grabs a hold of me tightly Then invest like a VC daily and nightly Will it ever stop? Yo, I don't know I trade coins and watch my portfolio grow To the extreme, bluetooth mic like a psycho Light up a stage, fleece a chump with an ICO

Who introduces new blockchains to solve specific problems though? That's why these platforms are generalised. Introducing a blockchain to solve a specific problem is like introducing a new operating system for your Web app.

I've literally sat across the table from people who have told me: "We have this problem. *explains problem in a few words* Can we use blockchain to solve that?" and I thought they were trolling me but they were serious.

My proudest moment last year was stopping an internal team considering the blockchain for a problem they had.

Can anyone explain blockchain? I keep getting laughed at for not knowing about this thing no one will tell me about because people are too busy laughing at my not knowing.

Structure for distributing computing among many hosts so that no one of them is in control. Kind of like torrents for processing
-
I am not sure the distributed nature of blockchain is either central nor required to its definition. Its "chain of custody" is its core definer imho.
-
what's the point of a blockchain if it's not distributed?
-
Security. The secure chain of immutable and auditable data. Distributing the effort of maintenance and processing is the gravy, if your solution can benefit from it. I have situations where a private blockchain has proven to be the perfect solution.
-
Interesting. Could you give me an example?
-
I am using it in a private network, to digitally sign(ature), secure & make auditable, HR documents and employment contracts that might end up in court years later. Data is super R-PII that needs to be stored at the level of court evidence. Its about security 1st, Pub & Dist 2nd.

How is immutability guaranteed?
