Proposal: add contract assertions to C++ Widget getWidget (index i) pre (i > 0) // precondition assertion post (w: w.index() == i); // postcondition assertion ## Proposal: add contract assertions to add contract assertions to C++ Widget getWidget (index i) pre (i > 0) // precondition assertion post (w: w.index() == i) // postcondition assertion { auto* db = getDatabase(); contract_assert high bar set for level of consensus. The proposal includes syntax for specifying three kinds of contract assertions: precondition assertions, postcondition assertions, and assertion statements. In addition

consensus protocols that do not require a native cryptocurrency to incent costly mining or to fuel smart contract execution. Avoidance of a cryptocurrency reduces some significant risk/attack vectors, and absence permissioned context, the risk of a participant intentionally introducing malicious code through a smart contract is diminished. First, the participants are known to one another and all actions, whether submitting submitting application transactions, modifying the configuration of the network or deploying a smart contract are recorded on the blockchain following an endorsement policy that was established for the network
