🛡️ Privacy is becoming essential infrastructure for DeFi trading. @AvailProject launches ShieldTX, its first perpetual trading application built on Avail's zero-knowledge privacy layer, designed to protect traders on @HyperliquidX from copy-trading bots. 🔍 The problem: On Hyperliquid, every position is public. Bots can track profitable wallets and replicate their trades within seconds, affecting execution prices and profitability. 📊 According to ShieldTX's research, copy-trading cost top traders a median of 63 basis points per trade over 30 days. 🔐 The solution: ShieldTX opens each position through a fresh wallet with no visible onchain link to the trader's identity or other positions, while preserving a complete transaction history for audits and compliance. 🚀 Why it matters: ShieldTX brings Avail's zero-knowledge privacy technology into a real trading application, demonstrating how privacy can become a core component of DeFi infrastructure rather than an optional feature. As validators securing Avail, we're excited to see the ecosystem expanding into practical applications that address real market challenges. 🔎 Check if someone is copying your trades: scanner.shieldtx.xyz 📰 Full coverage by The Block: theblock.co/news/defi/2026-1… more info 👀👇

☕🚀 1 million TPS with subsecond finality. @EspressoSys is pushing the boundaries of blockchain scalability. Espresso has demonstrated impressive performance in its latest benchmark: ⚡ ~1M TPS, equivalent to one million stablecoin transfers per second. 📊 181 MB/s of data throughput. ⏱️ 337 ms average finality, remaining below one second (778 ms) at full load. 🌍 Tested across 100 nodes with emulated global network latency. 🔍 What makes this possible? Espresso focuses on what it does best: consensus on transaction ordering and data availability, leaving execution to the chains built on top of it. As transaction sizes grow with post-quantum signatures and privacy proofs, and AI agents drive increasingly higher volumes, infrastructure must deliver performance not only under normal conditions, but also under peak demand. 🛠️ At Cumulo, we're proud to be Espresso validators, contributing to the infrastructure securing the network and supporting its continued evolution. 🔗 Read the full benchmark results: medium.com/@espressosys/scal…

🚀 The $GEN Airdrop registration is officially OPEN! An exciting milestone for the @GenLayer ecosystem and everyone who has contributed to its development. 🛠️ At Cumulo, we've been supporting GenLayer as validators since the early testnet stages, contributing infrastructure, technical expertise, and community support. It's great to see the project moving forward and recognizing its early contributors! 💪 📅 Registration closes October 26. ⚠️ Always use official links and never share your seed phrase. 👇

🚀 Celestia Fibre is LIVE on Mainnet! A major milestone for @celestia. With the activation of v10, Fibre is officially live, introducing a new validator-operated protocol for high-throughput blob publishing. ⚙️ How does Fibre work? Validators register Fibre servers on-chain to receive, sign and retain published data. Once signatures representing at least 2/3 of the stake are collected, the blob payment can be settled. 🛠️ Cumulo is live from day one! Our Fibre server is registered on-chain and has been operational since mainnet activation, contributing to the infrastructure supporting Celestia's new data availability capabilities. 📊 Transparency matters. We've made our Fibre Mainnet Report publicly available, providing visibility into: 🔹 Stake ready to settle blob payments 🔹 Registered and active Fibre servers 🔹 Data retention and availability 🔹 Published blobs and associated fees 🔎 Explore Fibre's activity on mainnet: cumulo.pro/services/celestia… 🔧 Explore all our Fibre services, already live and available to the community: cumulo.pro/services/celestia… 💜 As a Celestia validator, Cumulo remains committed to reliable infrastructure, operational transparency and the continued growth of the network. Fibre is live. We're building and validating alongside it.

🗳️ Cumulo votes YES to exploring @Starknet as an independent post-quantum L1! We've voted YES on the governance proposal "Should Starknet become an independent post-quantum L1?" 🔍 What does this vote mean? This is a vote to research the possibility, not to approve the transition itself. Starknet already has a strong foundation for quantum resistance thanks to its hash-based STARK proofs and native account abstraction. However, some critical components, including bridging and data availability, still depend on Ethereum. Exploring greater independence could give Starknet more control over its long-term security roadmap. 🛠️ Cumulo's commitment As an active Starknet validator and infrastructure provider, we're ready to contribute to this research through: 🔹 Validator infrastructure on Mainnet and Sepolia. 🔹 Public RPC and WebSocket endpoints for developers. 🔹 Early participation in potential testnets. 🔹 Technical testing, issue reporting and operational feedback. We believe validators should do more than secure the network. They should actively contribute to its technical evolution and long-term resilience. 🤝 Starknet's future security is a collective responsibility. We encourage the community to review the proposal, participate in the discussion and cast their vote. 🗳️ Vote: governance.starknet.io/#/s:s… 💬 Discussion: community.starknet.io/t/shou… 🔐 Stake your STRK with Cumulo and support a validator committed to security, transparency and the evolution of Starknet.

🚀 @celestia v10 (Fibre): the mainnet activation process is underway Fibre introduces a new data availability protocol that runs alongside Layer 1, targeting 1 Tb/s of blockspace. A leap in capacity that opens the door to applications needing to publish large volumes of data at low cost: AI agent payments, micropayments and financial applications at global scale. 🗳️ Where are we now? The upgrade is in the signaling phase: validators confirm on-chain that they are ready to upgrade, with their support weighted by voting power. 📊 Progress in this report: 🔹 52.32% of voting power 🔹 41 of 95 validators ⏳ When does it activate? Once 83.33% of voting power (5/6) is reached, a 7-day countdown begins. The upgrade activates automatically at the end of that period. The threshold depends on accumulated voting power, not the number of validators. 🔐 If you have TIA staked, no action is required. 🔎 Follow the process through Cumulo’s Signal Tracker: see which validators have confirmed their readiness and at which block height. cumulo.pro/services/celestia… 🛠️ Cumulo, as a committed validator to the project, we are ready for v10.

💳 @Concordium joined the Mastercard Crypto Partner Program. Payments are already moving on-chain: 🔹 Stablecoins. 🔹 B2B transactions. 🔹 Cross-border payments. 🔹 AI agents making payments on their own. One question connects all these flows: Who is behind the transaction, and who is accountable? 🔐 Concordium brings verifiable identity to the protocol: • Identity proofs without exposing personal data. • Agents linked to verified owners. • Verification without sharing documents with the counterparty. 🌐 Now it brings that technology into payment standards discussions with Mastercard and its ecosystem. 🛠️ At Cumulo, as Concordium validators, we help secure the network supporting this identity layer.🤝 Stake your CCD with Cumulo and help secure Concordium. On-chain payments. Verifiable identity. Accountability.

🚀 Fibre reaches 3.07 Tb/s @celestia’s Fibre just demonstrated what scaling data availability can look like. 💳 The scale? Enough capacity to publish a volume of data equivalent to EVERY transaction Visa processed in 2025 in just over two minutes. ⚙️ This measured the full pipeline: 🔹 Encoding fresh blobs 🔹 Distributing and storing data pieces 🔹 Collecting validator signatures 🔹 Recording commitments onchain Only blob data confirmed onchain counted toward the result. 🌍 Why does this matter? AI agents making payments. Global finance moving onchain. Applications generating far more data than today’s blockchains can support. They all need room to grow. Fibre sends blob data directly to validators, while Celestia records the commitments and signatures. That separation opens the door to much greater data availability capacity. 🔬 Context matters: this benchmark used an experimental performance branch and settings that will differ from the initial mainnet release. The result demonstrates potential. Mainnet capacity will start aligned with early demand and grow as usage increases. ☁️ At Cumulo, we operate validator infrastructure on Celestia and follow the technical advances that make larger-scale applications possible. You can stake your TIA with us. 👇 Read Celestia’s post below for the full benchmark breakdown and Fibre’s next steps.
