Hashgraph 10.0.0-beta5

Version 10.0.0 includes upgraded gRPC support libraries; preliminary support for Moniker (EVM Public Key Address Hash), and other additions to the HAPI 0.35. Also includes a new client feature for submitting externally created transactions with the new SubmitExternalTransactionAsync method, a new Gossip Node PingAsync method and enhancements in Private and Public import options.

Breaking Changes: Since, the native .NET DateTime object does not provide sufficient time resolution to properly represent an Hedera Consensus Time Stamp, most portions of the API surface area have swapped a new object ConsensusTimeStamp in place of DateTime. This is a sweeping and large change to the SDK. The ConsensusTimeStamp object provides an implicit cast from a DateTime to help aid in the transition from 9.0 sdk versions to 10.0. Be advised: converting a ConsensusTimeStamp to a native DateTime object can cause a loss of information (the HAPI smallest unit of time is the nano seconds, the DateTime’s smallest unit of time is 100 nanoseconds). The ConsensusTimeStamp was introduced in Beta 2 and is still a work in progress and may continue to have breaking changes in upcoming beta releases. Additionally, Endorsment has removed the PublicKey property in favor of a new ToBytes() method providing additional options when converting endorsement key values to byte array outputs.
