No serious blockchain relies on proof-of-work. Bitcoin (being forked now) doesn't and ethereum (already forked twice) definitely doesn't. Blockchains are a social construct and what ultimately protects them are the participants. E

It's sort of a silly question. It's like asking how telephones can solve a problem. The blockchain is a network not unlike the web, the telephone network, and the highway network. Networks don't solve problems in themselves t

This is a common error. The blockchain itself doesn't make money. Just like the internet itself doesn't make money. People build collaboration models on top of the communication protocols and they make money. (You still need to pa

It's a public database. That's it. Anybody can write to the database and anybody can read from it. The problem is that whenever you have a public anything there will be spam. People will come along and they will fill the space u

It's because there is no meaningful parallel. Conversations are not economic transactions. Period. You can try to stretch analogies ("walking is illegal because of traffic lights!1") but that's stupid and unhelpful. The

Mutiny is likely. American officers in particular will tend not to follow orders to commit an obvious war crime. This isn't an extralegal check , it's very much legal. But the system will fail if "the whole chain is stupid.&q

This actually does look great. There's real value here. In a world being overrun with services what's desperately needed is an orchestration language. Such a language is severely focused on consuming services/messages, conver

There is no easy answer here. Where and when validation happens requires some careful analysis. I find it helps a lot to think carefully about (1) message validation -- is this a valid message? (2) entity validation -- is this entity in a v

Clean architecture is just repackaged DDD. I sympathize with what Bob is trying to do though -- for some reason this stuff often doesn't "click" with many developers until they see it and then it seems "obvious." I

See my comment below. The language of the business will almost always guide the design in the right direction. There are rare cases where the business is unaware of a more "essential truth." This isn't about OO it's abou

Registration is definitely not a property of the student. It's always a good idea in these situations to appeal to real life. The actual business will point the way of the business simulation. In the real world we don't ask stud

Everybody knows "exactly once" means deduplication. This is not exactly a new problem. That said it's still a difficult problem and I actually wish people would stop trying to roll their own schemes. For example, this scheme

> 60 years ago the US built the interstate highway system. I think this is the point. The US spent roughly half a trillion dollars to build ~40,000 miles of road. There was a great deal of corruption as well as massive political conflict

It's also worth noting Singapore is certainly not a market-based system. Singapore's healtcare efficiency is completely the result of mandatory saving programs, a government funded insurance scheme for the poor and strict price co

Cost disease is definitely a real thing but you should be very wary of the diagnoses proposed by these amateur (libertarian) bloggers. Even a cursory analysis reveals that attempts to blame regulation, utilization, or government spending do
