23 Jun Key #technology concepts behind @Faceboook #cryptocurrency are #openSource & documentation is available online- Move: A Language With Programmable Resources for #Libra #Blockchain
We present Move, a safe and flexible programming language for the Libra Blockchain. Move is an executable bytecode language used to implement custom transactions and smart contracts. The key feature of Move is the ability to define custom resource types with semantics inspired by linear logic: a resource can never be copied or implicitly discarded, only moved between program storage locations. These safety guarantees are enforced statically by Move’s type system. Despite these special protections, resources are ordinary program values — they can be stored in data structures, passed as arguments to procedures, and so on. First-class resources are a very general concept that programmers can use not only to implement safe digital assets but also to write correct business logic for wrapping assets and enforcing access control policies. The safety and expressivity of Move have enabled us to implement significant parts of the Libra protocol in Move, including Libra coin, transaction processing, and validator management.

WHY IT MATTERS: Facebook announcement of its cryptocurrency called LIBRA will generate many comments but I expect few will take time to look at the technology behind the solution. Here, the LIBRA new programming language MOVE is explained in a detailed whitepaper.
IMHO this is the most interesting piece as it lays out the required components to implement a blockchain solution. This will require knowledge and expertise that today few have. If LIBRA is a commercial success then expect others to leverage the same technology in their solutions. Thus, worth reading.
