@neo-project/core Please take special look into HashAlgorithm.None I think that is well implemented and it can't produce a state difference in other places

* Implement NotaryAssisted transaction attribute Close #2896. Use a stub for native Notary contract hash since this contract is not implemented yet. Thus, technically, NotaryAssisted attribute verification will always fail on real network until native Notary is implemented. Signed-off-by: Anna Shaleva <[email protected]> * Payloads: add doc to CalculateNetworkFee method of NotaryAssisted attribute Signed-off-by: Anna Shaleva <[email protected]> * Native: add NotaryAssisted attributes handler to Gas OnPersist Transactions network fee should be split between Primary node and Notary nodes. Signed-off-by: Anna Shaleva <[email protected]> * Payloads: adjust comment to NotaryAssisted attribute Signed-off-by: Anna Shaleva <[email protected]> * Payloads: temporary use hard-coded Notary contract hash Once Notary contract is implemented, this hash will be replaced by a proper Notary contract hash. The exact value won't be changed since Notary contract has constant hash as any other native contract. Signed-off-by: Anna Shaleva <[email protected]> * Payloads: replace hard-coded Notary hash value with calculated one No functional changes, just a refactoring for better code readability. Signed-off-by: Anna Shaleva <[email protected]> * NeoModules: integrate NotaryAssisted attribute Port the neo-project/neo-modules#884.

Signed-off-by: Roman Khimov <[email protected]> * WitnessCondition: unify nesting checks, fix MaxNestingDepth 1. We have some duplication around "maxNestDepth <= 0" checks. 2. If we're to fix them by moving to DeserializeFrom() and thereby affecting all types of conditions we can discover a simple truth about conditions that was hidden previously: our real supported MaxNestingDepth is 3, not 2. 3. Test_WitnessCondition_Nesting works as before, check it there, we have And->And->Boolean and other nesting cases, 3-4 elements in the chain, not 2.
