In fact, Vitalik Buterin, the founder and spiritual leader of the Ethereum movement, was originally a bitcoiner, and he was only created Ethereum because the Bitcoin core developers at the time deliberately went out of their way to disable many of the functionalities which would allow for a programming language for smart contracts to be done on Bitcoin itself. So Vitalik did exactly what any good decentralist did when he was faced with oppression by the established regime. He left and did his own thing.
He went and started designing Ethereum. He wanted a turning complete language so that it would be easy for developers to write smart contracts. But a turning complete language would mean that infinite loops would be possible, which would be a bad thing in a globally decentralized blockchain. But this introduced a whole new category of complications: Relative to the total computational capacity of the whole network?
How would this scale as time went on? He decided that the protocol should just change the rates every so often, by edict given by the outside world.
Economically speaking, Ethereum was already becoming much more complex than Bitcoin, and writing and testing smart contracts could sometimes get costly, as your bugs will burn away your ETH as you make mistakes.
To further the issues, Ethereum has some serious scaling hurdles. Once many people start using the application at the same time, the network floods with transactions and the whole blockchain slows to a crawl. And what is worse, every Ethereum server is also doing all the calculations for the Crypto Kitten decentralized application, even if you are not using it.
No wonder they have such a doozy of a time trying to scale Ethereum past the point where one popular application can wreak havoc on the network. Well now, why do I bring up all these criticisms on ETH? In fact, I have great respect for Vitalik and many smart contract developers that I have met and know as they are truly breaking new ground in the space, and it is on the shoulders of their hard work that we will carve out the path to the digital frontier of the future.
But how you ask? Did Vitalik miss something? Because the Bitcoin that he left is still stuck exactly as he left it back in We are, of course talking about Bitcoin Cash, the offspring of legacy Bitcoin that decided that hard forks were an upgrade mechanism and that it would be OK to grow the network and add new or re-enable old features on it.
It is exactly the latter that will usher in the new age of smart contract development. For the technically inclined, the analogy would be the Bitcoin blockchain transactions effectively becomes a micro instruction table, a set of CPU registers, and a program stack pointer.
All the data, the code, and storage is elsewhere. This makes the Bitcoin model much simpler than the Ethereum model store and compute everything on the blockchain nodes. Everything else about the Bitcoin design is fairly simple and straight forward.
Understand that we can still leverage tools What's the point of front-end user validations if I have a public backend made by smart contracts hosted on the blockchain? As long as uPort isn't implemented as a Read uPort Persona from Registry I'm trying to read a profile via uport-persona. In doc it sounds easy but I can't access to my persona. Different uPort provider I'm trying to integrate uPort in one of my project and, the first thing that I noticed are the different ways to give a provider: Where find Uport mobile web app some one knows where I can find the Uport mobile App.
