Podcast Notes | Interview with the Zcash Core Team: Breaking Through 50,000 TPS and Post-Quantum Defense, Evaluating ZEC’s Long-Term Bull Case
Compiled & Adapted by: TechFlow
TechFlow Editorial: In today's rapidly evolving landscape of AI models and on-chain clustering analysis, the originally touted "transparent ledger" of public chains is swiftly becoming an inescapable surveillance nightmare. Every on-chain interaction, centralized exchange deposit/withdrawal record, or even a simple IP leak can be cross-correlated by advanced automated algorithms, completely stripping ordinary users' real-world identities, business dealings, and entire asset trails. At this historical inflection point, privacy cryptography pioneer Zcash is witnessing its most critical technological leap since its inception ten years ago.
This episode of Bankless features Zcash co-founder and Halo proof system inventor alongside Tachyon lead developer Sean Bowe, and Osmosis core architect alongside Tachyon cryptography researcher Dev Ojha.
The two core builders provide an in-depth analysis of Zcash's comprehensive technical roadmap covering scalability, user experience, and long-term security: from the Tachyon architecture, which recursively folds millions of proofs into a single ZKP for full-node verification loads, to engineering breakthroughs pushing full-chain throughput to 100 MB/s and supporting 50,000 TPS; from addressing the industry-wide pain point of light wallet scanning leaks via Private Information Retrieval (PIR), to establishing three phased pillars for post-quantum migration to secure quantum recoverability.
They firmly reiterate that in a future where global digital surveillance and centralized censorship are tightening their grip, only uncompromising cryptographic hard privacy serves as the ultimate defense line for safeguarding humanity's free financial transactions.

Original Title: The Complete Zcash Roadmap
Air Date: 2026-11-02
Key Takeaways
Transparent Ledgers Become One-Way Surveillance Hell in the AI Era: As on-chain tracking probes evolve in tandem with large language models, every leaked centralized exchange address becomes an anchor for correlating a user's entire network assets. Transparent public chains can no longer provide basic transaction security. Strong privacy protection is no longer a niche preference but a foundational necessity for all economic activity.
Refusing to Compromise on Privacy Protocol Foundations: The Zcash team explicitly rejects any backdoor-laden or 99.9% compromised privacy solutions. Weak privacy and mixing pools fall apart under long-term, multi-dimensional meta-analysis. Only mathematically perfect zero-knowledge proofs can withstand cross-sovereign censorship and de-anonymization probes.
Tachyon Architecture Reshapes Full-Node Verification Compute Model: Historically, if a block contained 1 million transactions, full nodes had to verify 1 million independent zero-knowledge proofs one by one. Tachyon introduces a novel recursive ZKP framework that recursively folds millions of proofs into a single minimal ZKP, completely decoupling full-node verification costs from total transaction volume.
Throughput Engineering Leaps to 50K TPS: Zcash's current full-chain data throughput is only ~60 KB/s. The Tachyon roadmap reduces block times to 25 seconds, introduces erasure coding sharding, and leverages advanced Gossip propagation mechanisms similar to Celestia, pushing data bandwidth to 100 MB/s and sprinting toward global payment network scale (50K TPS).
Private Information Retrieval (PIR) Solves Light Wallet Scanning Bottlenecks: Previously, mobile light wallets had to download massive amounts of on-chain blocks and locally decrypt/probe transactions, facing deadlocks of computational exhaustion and traffic leakage. By introducing PIR, light wallets can make anonymous queries to non-custodial RPCs, with servers returning matched assets without ever knowing the query target, achieving extreme lightness and zero metadata leakage.
Three Pillars of Defense Against Quantum Threats: Zcash has established a clear post-quantum migration route: Pillar 1 is "Quantum Recoverability," ensuring that even if future quantum computers break discrete log signatures, hidden fund ownership cannot be forged; Pillar 2 upgrades the transparent transaction pool to post-quantum cryptography; Pillar 3 transitions entirely to lattice-based cryptography proof systems.
Formal Verification and Multi-Hypothesis Defense-in-Depth: Facing dimensional strikes from AI automated hackers and vulnerability mining tools, Tachyon's core circuits implement rigorous formal mathematical verification. The protocol also avoids binding security to a single cryptographic assumption, constructing highly resilient, redundant multiple defense layers.
Prioritizing Private Payments First & Governance Reform: Zcash insists on peer-to-peer private e-cash as the absolute core, avoiding sacrificing security by blindly adopting general-purpose Turing-complete smart contracts. On governance, the team is driving Coinholder Voting and Network Sustainability Modules (NSM) to摆脱 traditional development fund centralization dependencies.
Key Insights
Sean Bowe: "Every time you initiate a transfer on a transparent ledger, you should feel profound anxiety. In the era of large models, every on-chain interaction permanently exposes your entire wallet's income/expense logs, counterparty information, and real-life trajectory to thousands of automated data crawlers."
Dev Ojha: "Throughout the history of technological evolution, whenever Zcash makes major decisions on cryptographic architecture, the entire industry follows suit, especially the Ethereum ecosystem. From zk-SNARKs to trustless initialization Halo recursion, Zcash has consistently pioneered cutting-edge technological high grounds for the industry."
Sean Bowe: "We will never bow down on privacy底线. Leaving even a sliver of a so-called compliance backdoor in an encryption system, or attempting to create some '99.9% privacy,' would instantly collapse the system's trust foundation. Mathematics is the only arbiter, and pure privacy is our core value."
Dev Ojha: "Anonymity always depends on system activity. The entropy of the privacy set in a network processing a thousand payments per second is vastly higher than in an isolated island with one weekly transaction. Scalability itself is privacy's strongest armor. Global-scale high throughput is the necessary path to absolute anonymity."
Sean Bowe: "Coinholders are the blood of the entire protocol. No matter how elegant the cryptography or flawless the academic papers, what ultimately determines Zcash's direction is the global supporters who hold firm and use ZEC over long cycles. Developers' mission is to forge the most reliable tools for freedom for them."
Dev Ojha: "If full-node verification is the backbone of blockchain, light client experience is the lifeline to billions of users. We cannot expect average people to download tens of gigabytes of data every time they open a mobile wallet. Through PIR, we have achieved millisecond-level instant synchronization without revealing any identity information to the server for the first time."
Main Article
1. Why Privacy Has Never Been More Urgent Than Now: The Fall of Transparent Ledgers in the AI Era
David Hoffman: Welcome to Bankless. Today we sit down to deeply explore one of crypto's oldest yet most controversial topics: private currency. We're joined by Zcash co-founder and cryptography pioneer Sean Bowe, and renowned cryptography researcher Dev Ojha. For past cycles, many felt numbness toward privacy, believing transparent ledgers were sufficient. But with the rise of artificial intelligence, reality seems to be undergoing a violent disruption. Sean Bowe, why do you feel unprecedented urgency at this exact node?
Sean Bowe: To be frank, if you are still frequently using transparent ledgers for daily transfers, you should genuinely feel your spine chill. About a decade ago, when I first entered this space, transparent blockchains looked merely like slightly flawed public databases; everyone thought generating different addresses could mask identities. But now, it's completely different. On-chain analytics firms possess enormously large physical tagging libraries, and combined with state-of-the-art AI large language models, the precision of on-chain data clustering has reached horrifying levels.
Dev Ojha: That is precisely the core pain point. The issue isn't just the blockchain's own transaction records; it's that every other data leak event in the world creates a multiplier effect. For example, if a centralized exchange suffers a user data leak and one of your deposit addresses gets bound to your real identity, AI algorithms can traverse forward and backward through your entire transaction graph in seconds, linking every friend you've transferred to, every project you've participated in, and every asset you've purchased over the past five years. It can even infer your daily routine and physical activity range.
Sean Bowe: In the past, only national intelligence agencies possessed this graph analysis capability, and ordinary people didn't think they'd be targets. But after AI model普及, the marginal cost of this global surveillance capability dropped to near zero. Any commercial rival, or even malicious ransomware operators, can acquire such on-chain intelligence at extremely low cost. We once thought transparency was an advantage, but against modern surveillance technology, transparent ledgers have directly turned into an omni-directional monitoring hell for all legitimate holders.
2. Refusing to Compromise on Privacy Protocol Foundations: Why 99.9% Privacy Equals Zero
David Hoffman: In recent years, regulatory pressure has been ubiquitous. Many teams began compromising, attempting "restricted privacy" or adding backdoors/key-sharing inspection mechanisms. Other projects claim that merely achieving 99.9% mixing or obfuscation is sufficient. How does Zcash view this philosophy of compromise?
Sean Bowe: Within Zcash's values, we resolutely refuse to bow down on privacy matters. There is an extremely brutal cryptographic truth: in privacy engineering, 99.9% privacy is indistinguishable from 0%. If a system claims it is private in 99.9% of scenarios, it means that 0.1% metadata leakage becomes the first domino to topple the entire system.
Dev Ojha: Mixers are the most typical negative examples. Many assume throwing tokens into a mixing pool and withdrawing them is safe. But as long as analysts possess a sufficiently long time horizon, coupled with minute differences in deposit/withdrawal amounts, network-layer IP traffic timestamps, and off-chain correlated data, de-anonymization is merely a matter of time. More importantly, in that model, your funding pool is extremely narrow. If anyone in the pool is suspected of illegal activity, all compliant participants' funds get indiscriminately tainted.
Sean Bowe: From day one, Zcash has stood on the purest zero-knowledge proofs. Inside the Shielded Pool, transaction amounts, senders, and receivers are all encrypted, leaving only an unforgeable, untraceable mathematical proof on-chain. Mathematics has no political bias, nor does it know how to submit to coercion. Once developers leave backdoors at the protocol level, those backdoors will inevitably be breached by hackers, authoritarian governments, and abusers of power. Pure hard privacy is our unshakable bottom line.
3. From Zero-Knowledge Proofs to Halo: How Zcash Shaped the Industry's Cryptographic Paradigm
David Hoffman: Many likely haven't realized that today's entire Ethereum Layer 2 ecosystem, modular execution layers, and various ZK-Rollups rely heavily on infrastructure originating from Zcash's early R&D. Dev Ojha, as a cross-ecosystem researcher, how do you evaluate Zcash's radiation across the cryptography field?
Dev Ojha: Without exaggeration, over the past decade, whenever Zcash made major decisions on technical routes and underlying cryptography, the entire crypto industry subsequently followed suit. The most typical case is Ethereum. When Zcash launched in 2016, the whole industry doubted whether zk-SNARKs could run in production environments, but Zcash proved their feasibility.
Sean Bowe: The thorniest problem back then was Trusted Setup. In early ZK constructions, generating public parameters required an incredibly complex ceremony. If secret key shards weren't utterly destroyed, the system faced fatal risks of infinite minting. We organized famous cryptographic ceremonies in 2017 and 2018, but deep down we knew relying on trusted setup remained a major compromise.
Dev Ojha: Later, Sean Bowe invented the Halo proof system, definitively ending the era of trusted setups. Halo enabled recursive proof composition for the first time without any initial trust assumptions. This achievement not only upgraded Zcash itself but directly inspired the entire modern ZK ecosystem including Mina, Polygon Zero, Scroll, and Starknet. Zcash has always been the beacon of cryptography innovation across the blockchain industry. While others chased short-term narratives, Zcash researchers chewed on the hardest mathematical bones at the lowest layer.
4. Scalability Is Privacy: Why Private Currency Must Possess Global-Scale Throughput
David Hoffman: This brings us to this podcast's heaviest technical core: scalability. Many hold a fixed mindset thinking Bitcoin's slowness allows it to be digital gold, so why must Zcash, as a store of value and private currency, pursue hundreds of thousands or even millions in TPS?
Sean Bowe: This is a massive cognitive fallacy. In the context of private currency, scalability isn't merely for fee reduction or speed boosts; scalability itself is the physical foundation of privacy.
Dev Ojha: Consider a simple logic: in a network with one transaction per week versus a network processing a thousand payments per second, which network's anonymity set is safer? Obviously the latter. If network processing capacity is exceedingly low, every user's hidden transfer stands isolated in time. Analysts can speculate participants through crude temporal correlation. High throughput means massive, dense transaction flows interweave continuously within extremely short windows, mathematically providing each user exponentially expanded cover populations.
Sean Bowe: Furthermore, if private currency aims to truly serve the globe, becoming a tool against hyperinflation and financial oppression, we must face the daily收支 scenarios of billions of ordinary people. If every transfer requires tens of dollars in fees and waits half an hour for confirmation, it degenerates into a niche toy for geeks. Without global-scale throughput, so-called financial freedom remains empty rhetoric.
5. Tachyon Core Decoded: Recursively Compressing Million Proofs into a Single ZKP
David Hoffman: So what exactly is Tachyon? How does it fundamentally rewrite Zcash's verification compute model? Please, Sean Bowe, meticulously dismantle this new architecture for us.
Sean Bowe: Tachyon is our flagship initiative to completely restructure Zcash's full-node load and transaction pipeline. To understand Tachyon, let's first examine the compute bottleneck traditional blockchains face. Imagine a block packs 1 million private transactions. Under existing architecture, full nodes must sequentially verify 1 million independent zero-knowledge proofs. Verifying one might take mere milliseconds, but multiplied by a million, a full node's compute resources and network bandwidth are instantly shattered, paralyzing the entire network.
Dev Ojha: Tachyon's core breakthrough precisely utilizes recursive zero-knowledge proofs. Put simply, while transactions are packed and propagated, proofs fold and nest within each other. When a block finally generates, the originally scattered millions of ZKPs are fully aggregated and distilled at the mathematical level into a single standalone ZKP. What does this mean? It means regardless of whether a block carries 10 or 1 million transactions, your verification workload as a network full node remains verifying that 1 final proof.
Sean Bowe: This completely alters the cost equation for blockchain full nodes. Verification complexity drops from O(N) straight to O(1). Full-node verification latency is compressed to microsecond levels. This drastically lowers hardware thresholds for running nodes and completely shatters the throughput ceiling constraining private transactions on-chain.
6. From 60 KB/s to 100 MB/s: Stress-Testing Engineering Limits at 50K TPS
David Hoffman: Verification compute is compressed to constant time, but another realistic constraint exists: physical network bandwidth. Today Zcash processes roughly 60 KB of data per second. To push throughput to global payment network scale, commonly called 50K TPS, underlying data throughput needs to reach a staggering 100 MB/s. How is this engineered?
Dev Ojha: 60 KB to 100 MB represents a multi-order-of-magnitude leap. We cannot rely on blindly amplifying block sizes, which causes severe orphan blocks and centralization. Our engineering implementation divides into clear tiers: Step one is the imminent network upgrade. Maintaining stable single-block size, we significantly compress block time, shrinking the average interval from slow cycles to around 25 seconds, immediately delivering triple baseline bandwidth gains.
Sean Bowe: But to sprint toward 100 MB/s, we must introduce core engineering weapons from modern modular data availability layers: Erasure Coding and Data Sharding Propagation. Mechanisms Ethereum introduced for Blobs, alongside Celestia's advanced broadcast structures, prove large-scale data doesn't require every node downloading linearly in full.
Dev Ojha: Combined with highly efficient Gossip topologies akin to Celestia Fiber, block data is segmented at the network layer and undergoes redundant erasure encoding. Nodes merely sample grab fragments to reconstruct global data states. Coupled with PoW block-time variance smoothing algorithms, we effectively counteract network traffic jitter caused by 1% ultra-fast blocks (250ms) and 1% ultra-slow blocks (>110s). This combination equips Zcash with immense bandwidth elasticity capable of bearing global commerce payment scales.
7. Light Client Scanning Deadlock: Breakthrough via Private Information Retrieval (PIR)
David Hoffman: Having covered full nodes, let's discuss the segment impacting ordinary users most: mobile wallets. Users of past Zcash mobile light wallets often complained: why does opening the wallet take minutes or more to sync and scan blocks? What's the mechanism behind this, and how do you plan to fix it?
Dev Ojha: This is a隐秘 deadlock plaguing the entire privacy public chain sector for nearly a decade. On transparent chains (like Ethereum or Solana), querying balances on a mobile wallet is straightforward: send an RPC request to Infura or Alchemy asking "how much is in this address," and the server instantly returns results. But Zcash is fully encrypted. Chain transactions lack plaintext addresses, and full nodes have no idea which transaction belongs to you.
Sean Bowe: So the old method was: the mobile wallet must download every Note Commitment from transaction outputs since last open, then locally attempt decryption with your private key one by one to see if it's yours. Feasible at low volumes, but once chain throughput reaches dozens of megabytes or even 100 MB/s, your phone battery drains in half an hour, and traffic explodes. Moreover, outsourcing your private key to a remote server to save trouble eradicates your privacy entirely.
Dev Ojha: Our ultimate solution introduces Private Information Retrieval (PIR), a frontier cryptographic primitive. PIR allows light clients to launch encrypted queries to full nodes or specialized RPCs: the server, completely unaware of which account or funds you're querying, returns your exact transaction data slices through homomorphic mathematical computation.
Sean Bowe: This completely decouples light wallets from full-chain throughput. Mobile terminals no longer bear heavy data downloads and local traversal computes. Syncing shrinks to milliseconds, simultaneously eliminating metadata leakage risks where RPC nodes speculate user behavior via request frequency patterns. This is the truly seamless privacy experience capable of supporting hundreds of millions of ordinary daily users.
8. Comprehensive Post-Quantum Defense: From Quantum Recoverability to Lattice-Based Migration
David Hoffman: Next enters the hardcore segment most geeks focus on: Post-Quantum. With quantum computing research breakthroughs, the industry harbors massive concerns over traditional cryptography based on elliptic curves and discrete log problems. Which Zcash components currently face quantum threats, and what's your defense blueprint?
Sean Bowe: Many assume quantum computers will crack everything overnight upon问世. But from a cryptographic engineering perspective, threats are layered. In existing Zcash, the perfect secrecy of private transactions relies on Pedersen commitments. From an information-theoretic standpoint, even facing arbitrarily powerful quantum computers, the contents of past shielded transactions remain absolutely secure and irreversibly decrypted. The actual risk lies in discrete log assumptions within digital signatures and proof systems.
Dev Ojha: If quantum computers mature, attackers can break current elliptic curve signatures to forge spending permissions for unspent assets. To counter this long-term threat, we formulated a three-phase post-quantum migration blueprint. Pillar One is the "Quantum Recoverability" we recently advanced.
Sean Bowe: The brilliance of Quantum Recoverability lies in pre-installing post-quantum resistant hash locks and multi-factor identity credentials within the protocol. Even in worst-case scenarios where a lower-tier discrete log signature scheme is suddenly broken by undisclosed quantum compute, attackers cannot directly steal user assets. Users can securely migrate assets to new defense pools at the protocol level backed by their retained post-quantum credentials.
Dev Ojha: Pillar Two upgrades currently residing transparent pool assets and interaction interfaces entirely to post-quantum native structures. Pillar Three smoothly transitions the entire zero-knowledge proof base toward Lattice-based Cryptography and pure hash construction proof systems. This is a profound defense requiring meticulous deployment years in advance. Zcash will establish unbreachable post-quantum barriers among mainstream public chains.
9. Rise of AI Automated Hackers & Formal Verification Defenses
David Hoffman: We discussed quantum threats, but many point out AI brings security dangers faster and more directly than quantum computing. When AI possesses极强的 mathematical deduction and code auditing capabilities, will automated vulnerability mining tools deliver devastating blows to complex ZK circuits?
Sean Bowe: This is a profoundly insightful and sobering reality. Discovering esoteric cryptographic circuit vulnerabilities previously demanded top mathematicians laboring months or years manually bounding conditions. Now we see state-of-the-art code large models and symbolic reasoning engines demonstrating astonishing automated vulnerability scanning abilities. Hackers needn't even understand the whole system; they deploy AI to hunt under-constrained circuit flaws.
Dev Ojha: Precisely why from Day One of developing Tachyon, we elevated Formal Verification to our highest priority standard. We can no longer rely on traditional human peer reviews or routine reports from audit firms. Within Tachyon's codebase, all constraint equations, state transition logics, and recursive folding steps must compile strict machine-proven mathematical certificates.
Sean Bowe: Formal verification operates like rigorously proving via computer programs that under any input combination, circuit behavior complies 100% with mathematical norms, harboring zero undefined edge states. Using mathematical tools to combat automated AI probes is our sole solution for maintaining absolute security in high-dimensional offense-defense博弈.
10. Multiple Cryptographic Assumptions: The Philosophy of Redundant Defense-in-Depth
David Hoffman: Many crypto systems bet everything on a single mathematical puzzle. If a specific bilinear pairing encounters trouble, the entire system collapses. How does Zcash practice "defense-in-depth" in system design?
Dev Ojha: In security engineering, never put all eggs in one basket. Our core principle builds systems founded on multiple mutually independent cryptographic assumptions. For example, in our asset protection design, even if theoretical breakthroughs later challenge the zero-knowledge completeness of proof systems, as long as the underlying hiding commitments for assets remain solid, funds absolutely won't inflate from thin air.
Sean Bowe: In other words, through layered decoupling, we separate the security of "anti-double-spend/anti-inflation" from the security of "privacy masking" onto entirely distinct mathematical assumptions. Should even one theoretical pillar show flaws decades later, the system retains second and third defense lines to halt catastrophic collapse. This multi-redundancy philosophy is fundamentally why Zcash survived multiple hard forks and tech iterations without a single inflation disaster.
11. Why Private E-Cash Must Precede General-Purpose Smart Contracts
David Hoffman: Many in the industry constantly ask: why did Zcash avoid joining Turing-complete smart contracts early on to build complex DeFi and massive ecosystems like Ethereum? Why persistently place "payments" in absolute priority?
Sean Bowe: Look at what unfolded on general-purpose smart contract chains over the past five years. Almost every week protocols lose billions to hackers via reentrancy bugs, oracle manipulations, and intricate interaction combos. If your underlying currency cannot guarantee ironclad peer-to-peer payment security, blindly stacking tens of thousands of lines of unverified contract code atop it merely transforms the system into a hacker ATM.
Dev Ojha: Currency must be minimalist, robust, and flaw-proof. Once you introduce a Turing-complete execution environment, system state explosion, verification complexity, and attack surfaces diffuse geometrically. Zcash's historical mission is foremost to become humanity's best peer-to-peer private e-cash. Build an indestructible private payment engine first. Future connectivity to other ecosystems happens safely via restricted Intents or cross-chain modules. Never invert cause and effect.
12. PoW Security Budgets, Network Sustainability Module & Community Governance
David Hoffman: Governance is the most discussed, contentious topic in Zcash history. Early Dev Funds subsidized massive foundational R&D via block reward splits, but sparked fierce博弈 over centralization and miner利益 dilution. With existing cycles approaching limits, how does Zcash solve long-term security budgets and development funding next?
Dev Ojha: This is the maturing labor pains decentralized protocols must endure. The early fixed-ratio block reward subsidy model fulfilled its historical mission, but long term, any centralized distribution entity inevitably becomes a single-point regulatory attack target.
Sean Bowe: We are actively advancing the Network Sustainability Module (NSM) and more transparent coinholder governance mechanisms. We aim to explore dynamic security budget models perfectly combining transaction fee capture with block rewards. Crucially, decision-making power must return decisively to the community.
Dev Ojha: We are stress-testing cryptography-verified Coinholder Voting. Holders can directly vote on major protocol upgrades and fund allocation by showcasing shielded holding proofs without exposing real addresses or balances. Handing protocol direction control to true stakeholders is the most effective path ending governance infighting.
13. ZEC Market Value, Regulatory Confrontation & Ultimate Vision
David Hoffman: Final question reserved for macro trends. Recently, several centralized exchanges delisted privacy tokens under compliance pressure, and ZEC endured prolonged market grinding. Facing potential sovereign regulatory blockade and market skepticism, what confidence do you two harbor for Zcash's future?
Sean Bowe: Every truly civilization-altering disruptive technology faces vehement resistance and suppression from incumbent beneficiary systems early on. When crypto initially emerged, mainstream mocked it as worthless foam. Now that transparent public chains are fully integrated into现行 financial surveillance frameworks, pure privacy currencies naturally become the final, fiercest battlefield.
Dev Ojha: Exchange delistings never strangle genuine cryptographic freedom. With decentralized non-custodial liquidity, cross-chain intent protocols, and smoother mobile wallets landing, private asset circulation on peer-to-peer networks becomes as physically unstoppable as sending emails. Market cyclical volatility is temporary. True underlying demand is erupting irrevocably.
Sean Bowe: When the future inevitably slides toward CBDCs and全天候 algorithmic surveillance, people will suddenly realize only assets like Zcash, welded with uncompromising privacy at the mathematical base and bearing zero backdoors, preserve personal sovereignty and wealth dignity as last sanctuaries. We spent a decade forging mathematical defenses precisely to welcome that moment's arrival.
