Scalable Privacy
summary
Proposal pairs quadratic sharding of the payment layer with recursive SNARKs built on a no-trusted-setup lower layer (bulletproof-like) so the chain scales horizontally without leaking the Zcash-grade shielded graph. Shards publish succinct per-period summaries that miners recursively aggregate à la Coda, replacing full broadcast with mixed nets to stop every wallet decrypting every transaction. Target is mobile-friendly 192-byte proofs, preserved nullifier/commitment correctness, and reduced cryptographic trust while keeping script complexity off-chain.
