Ethereum performance in .NET Core
summary
Nethermind is a .NET Core Ethereum client that proves high-performance parity with Go and Rust by shipping concrete optimizations: native C crypto where needed, a custom 256-bit struct plus BigInteger improvements (30–40% on .NET Core 2.1), AVX2 intrinsics, Span/BinaryPrimitives and dotnetty-style pooled buffers. A persistent 100,000-block integration benchmark and live sync peaks of ~17,000 blocks/sec demonstrate real gains; a hand-tuned BLAKE2 compress yields ~20x faster and 30x less allocation versus naive code. State size: ~40 GB across ~300M nodes.
