Satoshi, in his invention of the blockchain, had given us the inch, what is preventing other bodies or organization from taking the ell?
The fact that this whole "Blockchain technology" isn't really useful and Bitcoin is really the only succesful use so far. All the attempts to build something other than a cryptocurrency on blockchain has failed, and cryptocurrencies fail to compete with Bitcoin because they have far worse security both in terms of network fundamentals and in terms of code quality. So it's actually very hard to compete with Bitcoin because it's being developed by the most skilled people in the world in the field of cryptocurrency.
