Podcast Notes | A Conversation with the Zcash Core Team: Breaking Through 50,000 TPS and Quantum-Resistant Defense, Evaluating the Long-Term Growth Poten

Zcash core developers Sean Bowe and Dev Ojha outlined the protocol's full technical roadmap on a Bankless podcast, headlined by the Tachyon architecture, which recursively folds millions of zero-knowledge proofs into a single ZKP to decouple full-node validation costs from transaction volume. The roadmap targets a throughput leap from the current ~60 KB/s to 100 MB/s—supporting roughly 50,000 TPS—via 25-second block times, erasure-coded sharding, and Celestia-style gossip propagation. It also introduces Private Information Retrieval (PIR) so light wallets can sync with unhosted RPC servers without leaking metadata, addressing a long-standing scanning vulnerability. Quantum resilience is planned through three pillars: quantum-recoverable shielded funds, quantum-resistant transparent mempools, and a full transition to lattice-based proof systems, backed by formal verification of core circuits. The team reiterated its refusal of any "backdoored" or partial privacy compromises and is pursuing governance changes including coinholder voting and a Network Sustainability Module. Watch for Tachyon implementation milestones and whether Zcash's privacy-scaling blueprint, which has historically influenced Ethereum's zk ecosystem, drives broader adoption of similar designs.
