TLSNotary Performance Benchmarks (August 2025)
· 5 min read
Over the past months, we’ve made major performance leaps in TLSNotary. We implemented the VOLE-based IZK backend (QuickSilver) and introduced control-flow and MPC optimizations across the stack.
Starting with v0.1.0-alpha.8, QuickSilver replaced the older garbled-circuit proof backend, reducing bandwidth usage and sensitivity to latency. Subsequent releases added transcript hash commitments, low-bandwidth modes, faster APIs, and more. (https://github.com/tlsnotary/tlsn/releases)
These changes yield significant performance gains in both native and browser builds.
In this post, we share results from our new benchmarking harness and highlight how different network conditions (bandwidth, latency, response size) affect real-world performance.
