Designing a transaction oriented programming language


Blockchain programming languages have to be transaction oriented by design. Ideas might be taken from transaction oriented programming languages or early artificial intelligence approaches to implement procedural knowledge, like scripts or frames. Blockchain programming language has to have to following two main feature:

1. Even if the core can be realized by an imperative approach, each transaction must be supported by a strong declarative description providing elements for possible: 
- defining the input and output parameters of the transaction
- defining before and after safety checks for both the input and the output parameters
- defining the states that the transaction will change
- defining after and before safety checks for implied states.
- defining the list of cooperating transactions 
- defining advanced security model in a declarative way. 

2. The transaction must have a good and easy human readable approach. As blockchain implementations describe collaboration models between several actors, the best way would be to use and advanced hierarchical approach of artificial intelligence for representing procedural knowledge, like scripts. Such a formalism might have the following properties:
- the spot
- the scene
- the roles - actors
- properties and objects 
- scenes 
- activities - set of actions
