During March 2026, Troll Bellator contributed to the envoyproxy/envoy repository by implementing TLS certificate compression to optimize handshake efficiency for both QUIC and TCP connections. Using C++ and leveraging network programming expertise, Troll introduced Brotli and zlib-based compression in accordance with RFC 8879, reducing handshake size and bandwidth usage. The work involved refactoring the existing QUIC-specific handshake logic into a shared implementation for both QUIC and TCP TLS, maintaining backward compatibility and clean abstraction layers. This approach not only improved connection establishment speed but also facilitated easier future maintenance, demonstrating depth in protocol-level engineering and cross-protocol code reuse.
