Zakura Client Launches to Scale Zcash

Curated by · TechCapsules ·

AI-summarised brief · reviewed before publication

Zakura, a new Zcash full node client, has launched to facilitate scaling the network toward Visa- and Mastercard-level transaction throughput. Maintained independently by Sean Bowe and Dev Ojha, Zakura is a pruned, fast-syncing fork of the Zebra client, ensuring compatibility with the legacy zcashd software before its July 18 end of life. The release supports the upcoming Ironwood (NU6.3) upgrade, activating July 28, which introduces a turnstile mechanism to cap Orchard shielded pool withdrawals and mitigate risks from a historical soundness bug. By significantly reducing disk usage through pruning, Zakura allows nodes to download smaller, ready-made chain copies rather than syncing entire histories. This software represents the first live component of a broader strategy, including Project Tachyon, aimed at removing wallet performance bottlenecks and shrinking verification data. The initiative seeks to elevate Zcash from roughly one private transaction per second to handling tens of thousands, preserving strong privacy guarantees while achieving payment-network scale through independent development funded by private ZEC donations.

💡 Why It Matters

  • · Independent development challenges the Zcash Foundation's monopoly on node software, proving that community-led engineering can drive critical infrastructure upgrades.
  • · This decentralization of maintenance reduces single points of failure while directly addressing the technical bottlenecks preventing Zcash from competing with global payment giants.

Land-Based iGaming Infrastructure Sees Shift Toward Blockchain Integration Across New Platform Providers

Operators in the land‑based iGaming sector are increasingly testing hybrid models that blend traditional betting systems with blockchain technology. The goal is to use distributed ledgers for settlement, verification, and data parity across both physical and online platforms. Early pilots focus on real‑time data synchronization between retail terminals and digital sportsbooks, aiming to streamline reconciliation and risk management. Global investment in blockchain for gaming surpassed $19 billion in 2024, prompting firms to evaluate regulatory frameworks and the compatibility of legacy payment processors with new ledger‑based solutions.

💡 By unifying on‑premise and online betting data, operators can reduce reconciliation errors and enhance audit transparency, positioning themselves ahead of tightening regulatory scrutiny.

XRP Price Stays Near $1 as XRPL Growth and US Regulations Drive Optimism

XRP Price Stays Near $1 as XRPL Growth and US Regulations Drive…

XRP has maintained a price above the critical $1 support level, trading between $1.11 and $1.12 amid recent market swings. The token’s resilience is attributed to the XRP Ledger’s expanding use cases, including fast, low‑cost payments, tokenization, and stablecoin services, which have attracted enterprise interest. Investor sentiment has improved following progress in U.S. crypto regulation, notably the CLARITY Act, which promises clearer legal guidance. With a market cap near $70 billion and daily volume around $1.2 billion, XRP’s steady performance has drawn attention from traders and institutional investors alike.

💡 The combination of a robust ledger ecosystem and emerging regulatory clarity positions XRP as a more credible infrastructure asset, potentially accelerating institutional adoption and reshaping the broader crypto market’s perception of blockchain viability.

Web 3.0 adoption accelerates as decentralized digital infrastructure expands beyond early blockchain applications

Web 3.0 adoption accelerates as decentralized digital infrastructure expands beyond early blockchain…

The global Web 3.0 market, valued at $6.20 billion in 2025, is projected to surge to $161.21 billion by 2035, reflecting a 38.5% compound annual growth rate. Enterprises across finance, healthcare, gaming and supply‑chain are investing in decentralized platforms to gain tighter control over digital assets, identity and data ownership. Growth is fueled by broader blockchain adoption, the rise of decentralized applications, and the convergence of AI, cloud and IoT with distributed ledgers. Government programs, such as the European Blockchain Services Infrastructure, and corporate initiatives like Google Cloud’s expanded Blockchain Node Engine, are bolstering infrastructure readiness. Despite the upside, regulatory ambiguity, scalability limits, interoperability hurdles and a talent shortage pose notable constraints on widespread deployment.

💡 The rapid market expansion signals a shift from niche blockchain pilots to core business infrastructure, forcing regulators and tech talent pipelines to adapt at unprecedented speed.

XRP Ledger Secures Validator Approval For Landmark Update

XRP Ledger Secures Validator Approval For Landmark Update

The XRP Ledger (XRPL) is poised to activate a critical software patch that restructures ledger management, pending final validator approval. The update triggers a 14‑day countdown once a majority of validators signal readiness, marking the network’s first major protocol change since its 2012 launch. While consensus among core validators appears strong, a sizable portion of node operators have yet to install the patch, creating a disparity between governance decisions and on‑chain execution. This lag underscores the broader challenge of coordinating decentralized infrastructure upgrades without service interruption. XRPL’s developers emphasize that successful deployment will demonstrate the ledger’s capacity for sustainable evolution, balancing technical innovation with community‑driven governance mechanisms.

💡 The upgrade tests whether a mature blockchain can harmonize rapid technical change with decentralized coordination, a litmus test for long‑term resilience.

Inside Zcash’s new node that targets Visa-scale privacy at 50,000 transactions per second

Inside Zcash’s new node that targets Visa-scale privacy at 50,000 transactions per…

Zakura, a new Zcash full node client, launched at version 1.0.0 as a pruned, fast-syncing fork of Zebra. Maintained independently by Sean Bowe and Dev Ojha, the software supports the upcoming Ironwood upgrade activating July 28. This upgrade introduces a turnstile mechanism to cap withdrawals from the Orchard shielded pool, addressing a long-standing soundness bug that may have created counterfeit ZEC. Zakura replaces the legacy zcashd client, which ends support on July 18. The release is part of a broader initiative, including Project Tachyon, to scale Zcash to Visa-level throughput of 50,000 transactions per second. By shrinking verification data and removing wallet bottlenecks, the team aims to match global payment networks while preserving privacy. The project is funded by private ZEC donations rather than foundation grants, marking a significant shift in development structure and technical capability for the privacy-focused cryptocurrency network.

💡 Independent maintenance by cryptography founders signals a structural shift away from foundation reliance, potentially increasing network resilience. The Ironwood upgrade’s turnstile mechanism directly mitigates inflation risks from historical bugs, restoring trust in Zcash’s monetary policy.
