I feel it is necessary to mention that there's an enormous amount of snakeoil in the blockchain/appcoin/altcoin industry, and that there are hundreds if not thousands of people who have invented broken "solutions" to blockchain problems that they are trying to sell. Many of these solutions come from people who genuinely believe that they've solved fundamental problems with Bitcoin. But by and large, they have missed important security vectors. Writing a blockchain is a lot like rolling your own crypto - leave it to the experts, and don't trust one unless you've got a bunch of experts who agree that it seems sound. These problems are very hard. If you are wondering why Bitcoin has not adopted some interesting new technology despite years of dozens of experts doing their best to get scaling into Bitcoin, it's probably because the interesting new technology has some fatal flaw.
