[Cryptography] Quillon Graph: A private, post-quantum electronic cash system

[Viktor S. Kristensen]

  Z,
  Fair question. The 680K figure is find crates -name "*.rs" | xargs wc -l on our 81-crate workspace—no stdlib, no
  vendored deps, just our code. The Cargo.lock pulls in ~400 external crates; those aren't counted.

  Breakdown of what's actually there:

  q-api-server      93K   (REST/SSE, block production, mining API)
  q-storage         65K   (RocksDB layer, turbo-sync, state applicator)
  q-vm              53K   (WASM VM, sandboxed contract execution)
  q-network         45K   (libp2p, Kademlia, gossipsub, Tor transport)
  q-tor-client      27K   (circuit management, Dandelion++, bridges)
  q-quantum-mixing  26K   (ring signatures, Bulletproofs integration)
  q-ai-inference    20K   (distributed inference, tensor parallel)
  q-types           18K   (blocks, transactions, crypto primitives)
  tests             71K   (across all crates)
  ...61 other crates

  Could this be smaller? Certainly. A minimal "just consensus + signatures" implementation would be maybe 30-50K lines.
  But we're shipping:

  - Full ZK-STARK prover (no trusted setup)
  - Four-phase Tor integration with pluggable transports
  - WASM VM with gas metering and dual-sig auth
  - DEX with constant-product AMM
  - Height-gated upgrade system for mainnet safety

  The honest answer: we optimized for auditability and feature-completeness over minimalism. Each crate is independently
  testable with clear boundaries. A svelte implementation would be valuable for formal verification—not opposed to that as
   a future effort.

  If you want to dig in, the full source is at code.quillon.xyz (no auth required).

> Out of genuine curiosity (absolutely no critique): 680,000+ lines of Rust feels extraordinarily large, even for a reference implementation and even including tests, examples, tooling, and vendored deps. Do you include Rust core libs in the line count? Have you considered a minimal implementation (like a few hundred lines)?
