I'm curious about the development of application of Identity management in Blockchain platform, but I'm a bit confused about the technologies to use.
In short words, when is more convenient to develop an application coding in script and when is it better to use a high-level library like BitcoinJ or a service as Blockchain.info API?
I'm a Java developer and I'm more confortable using a Java Library like bitcoinJ, but I don't understand if, in this way, I can lose something in performance or expressivity or "semantic power" in regard to most raw-level scripting system of Bitcoin (that is a kind of assembler).
Thanks you in advance
