notes on the build
Snapshot
SP-DIFFER is a correctness project: compare multiple Silent Payments implementations, catch divergence, and turn every mismatch into a minimal reproducible case.
That is the right level of seriousness for protocol tooling. Instead of treating interoperability as an afterthought, the repository makes normalization, determinism, and repeatable failures part of the design itself.
Why I find it exciting
Even in scaffold form, it reflects the kind of engineering I trust: deterministic, careful, and more interested in correctness than noise.
what mattered
- Deterministic normalization contract for cross-implementation comparison.
- Reproducible mismatch artifacts as a first-class output.
- Documentation and repository structure laid out around maintainers, testing, and CI use.
