pb3-gen-sol is a proto3 to solidity library generator that supports proto3 native types and uses field option for solidity native types. Both the message and generated code are more efficient than other solutions. It also includes a library to decode protobuf wireformat.

Removing links to Erlang projects which are no longer maintained.

Added link to VSCode-Proto3 extension in Other Utilities section

I have added the xsrpcj RPC implementation for java

https://github.com/dcarp/protobuf-d is a conformance tested proto3
runtime library and code generator for D.

Add third-party RPC implementation: raster - a network framework supports pbrpc by 'service' keyword.

Add GDScript Protobuf implementation

Has support for protobuf v2.

Remove broken link to RPC implementation https://code.google.com/p/protorpc/. Going to this URL displays a 404 error message, with no indication that the project has a new location or still exists.

Add Awake Security's Haskell Protobuf and GRPC implementations

Add a link to my third party protobuf/gRPC implementation for GopherJS.

I added my project ProfaneDB, it is a database for Protocol Buffers objects. Written in C++, it uses gRPC as an interface for other languages.
It is still work in progress, but I'd love to get some feedback on it while I progress!

Github repo had moved, pointing to correct location.

* add Grpc Protobuf validation

Updated the location for `protobuf-maven-plugin`

Uses Google's C++ library for .proto parsing and uPB for protobuf
encoding/decoding; it supports both proto2 and proto3 syntax and
encoding/decoding is more than 10 times faster than pure-Perl
Google::ProtocolBuffers.

Add reference to Protocol Buffers Dynamic Schema (https://github.com/os72/protobuf-dynamic)

1.only support proto3
2.support oneof map
3.support nested message and enum for as3
