Add panic = 'abort' to all profiles (not just release) to avoid undefined behaviour

2

See https://trac.torproject.org/projects/tor/ticket/27199 , and the upstream Rust bug https://github.com/rust-lang/rust/issues/52652 (in particular my comment [here](https://github.com/rust-lang/rust/issues/52652#issuecomment-694952684)). We currently do set `panic = 'abort'` in the *release* profile of librustzcash, which is why...

See https://github.com/dalek-cryptography/subtle/issues/74#issuecomment-678401913

### Describe the issue In general, processors may have data operand-dependent timing for certain instructions, which results in a potential timing side channel for cryptographic code, even when that code...

Post-quantum privacy for Zcash

Split from #805, which considers a fully post-quantum Zcash, i.e. one that would be post-quantum secure for balance, spendability, etc. This issue focusses on post-quantum privacy, and in particular, changing...

Shielded transaction aggregates

## Is your feature request related to a problem? Please describe. If Zcash achieves significantly higher usage, then the overall verification and transaction bandwidth cost will become a problem. In...

Fully post-quantum Zcash

33

There are three components necessary for a post-quantum Zcash: - a plausibly post-quantum [PPQ] public key encryption scheme; - reanalysis of symmetric crypto parameter choices against quantum attacks; - a...

## Is your feature request related to a problem? Please describe. Sometimes we want to return either a success result or error information from a C++ function. Existing ways to...
