Or lets turn the question more philosophical: What does it mean for your app to be decentralized? What are the requirements and what advantages does it bring?

Hi .. I finally found a solution: I've declared some application variables for my APP, normally APEX doesn't allow you to declare items as NONCE[0] (the brackrt signs are not not authorized n in names so I've created variables NONCE1, NONCE2 (and few others) then I've updated the database directly (the APP definition) to rename them as NONCE[0] and NONCE[1], and it's working.. (I know this is not super clean but at least it work until i find a better solution) ..
