Live peers for XRPL EVM: keeping node connectivity practical 🌐 Running an XRPL EVM node means dealing with one of the most common infrastructure problems: peer connectivity. Static peer lists can be useful as a starting point, but they become outdated very quickly. A peer that was visible from one node yesterday may not be reachable from the outside today, and when a node starts struggling to connect, that difference matters. That is the reason behind Cumulo Live Peers ⚡ We built it as a live peer checker for XRPL EVM mainnet and testnet, updated every 30 minutes and available through both a public dashboard and API. The goal is simple: continuously detect which peers are actually reachable, remove unstable entries, and provide node operators with a peer list that is useful in real operational situations. How Cumulo Live Peers works 🛠️ Every 30 minutes, the system creates a new candidate pool using several sources: 🧩 Our own XRPL EVM nodes 🌐 RPC endpoints from validators in the ecosystem 📚 Addrbooks and peer lists collected from validator resources 🤝 Peers contributed directly by operators Each candidate is then tested through a direct TCP check against its P2P port. If a peer cannot be reached from the outside, it is not included in the published list. We also avoid adding peers just because they appeared once. To be included, a peer needs to show consistent stability across roughly the last 5 hours of observations. If it disappears, becomes unreachable or stops behaving reliably, it is automatically removed after a few cycles. A useful list, not just a longer one 🔎 It is designed to publish a peer list that operators can actually trust when they need to recover or improve connectivity. Peers are scored based on: 📈 Recent stability 🔁 Outbound activity ✅ How many independent sources confirmed the same peer 🌍 Geographic diversity This helps reduce noise and avoid peer lists filled with random entries that may not be helpful in practice. For operators, especially during a connectivity issue, quality matters more than quantity. Ready to use 🚀 The live peer lists are already available here: 🔗 Mainnet: cumulo.pro/services/xrplevm_… 🔗 Testnet: cumulo.pro/services/xrplevm/… 📖 Full technical documentation: github.com/Cumulo-pro/Cumulo… Why this matters 🧠 At Cumulo, we operate validator infrastructure across XRPL EVM, Cosmos and modular networks, and peer connectivity is one of those topics that looks simple until something breaks. Cumulo Live Peers is our way to make this part of node operations more practical for the XRPL EVM ecosystem: live checks, public data, reproducible logic and continuously updated peer lists without manual maintenance. We hope this becomes useful for XRPL EVM validators, node operators and infrastructure teams. Feedback, suggestions and validator contributions are very welcome 🤝

🗳️ We voted YES to Starknet v0.14.3 Voting is now active to approve @Starknet v0.14.3 as a minor upgrade, and Cumulo has already cast its vote in favor. This upgrade brings key improvements to the network: ⚡️ More frequent blocks and lower latency with SNIP-40 💸 Dynamic L2 gas base fee tied to the STRK price through SNIP-35, improving fee predictability ⚠️ RPC 0.8 deprecation: teams should migrate to RPC 0.9 or 0.10.1 / 0.10.2 📅 Sepolia testnet: June 9 📅 Mainnet target: June 22, 2026 As validators on Starknet, we continue supporting upgrades that make the network more efficient, predictable, and ready for its next stage of decentralization.

⚛️ What really happens with gas when you pay many recipients at once on @cosmos ? We published a new article exploring multi-send on @cosmoshub through a real testnet case study, using actual transactions to measure how gas behaves as the number of recipients increases 📊 With Gaia v27.0.0, multi-send gas is no longer purely linear. It now includes a quadratic surcharge designed to make large-scale spam increasingly expensive, while keeping legitimate use cases accessible 🛡️ In the article, we cover: 🔹 What multi-send is and why it matters 🔹 How gas works in Cosmos Hub 🔹 The quadratic surcharge introduced in Gaia v27.0.0 🔹 Real gas data from testnet transactions 🔹 The empirical formula behind the total gas cost 🔹 Why this matters for validators, developers, protocols and users At Cumulo, we are validators on @cosmoshub ⚛️ and for us, running infrastructure also means testing, measuring and explaining how the network behaves in practice.

🌐 Cumulo Live Peers: from static peer lists to real-time peer lists Cumulo Live Peers for @celestia is a live peer checker for Celestia mainnet and Mocha testnet, designed to help validators and infrastructure teams find peers that are actually reachable and useful right now. When a node starts having connectivity issues, a static list is often not enough. What operators need in that moment is simple: peers that are reachable from the outside, stable over time, and ready to use. Cumulo Live Peers checks peer availability every 30 minutes and builds updated lists using multiple sources: 🔎 Our own Celestia nodes 🌐 RPC endpoints from validators in the ecosystem 📚 Addrbooks and public peer lists 🤝 Peers contributed directly by operators Each candidate peer is tested through a direct TCP check against its P2P port. If a peer is not reachable from the outside, it does not make it into the published list. We also avoid publishing peers just because they appeared once. To be included, a peer needs to show consistent stability across several observation cycles. The goal is not to publish the biggest possible peer list. The goal is to publish a useful one. Peers are scored based on: ✅ Recent stability ✅ Outbound activity ✅ Confirmation from independent sources ✅ Geographic diversity You can use the live peer lists here: Mainnet: cumulo.pro/services/celestia… Mocha testnet: cumulo.pro/services/celestia… Full technical documentation: github.com/Cumulo-pro/Cumulo… We also maintain validator resource lists for Celestia mainnet and Mocha, so validators can contribute RPCs, addrbooks and peers via PR. The more validators contribute, the better the system becomes for everyone. We shared the full explanation on the Celestia Forum 👇 forum.celestia.org/t/cumulo-… This is part of how we approach our role as @celestia validators at Cumulo: building tools that reflect our vision of solid, transparent and reliable infrastructure, while adding real technical value to the networks we support.🌌

An important step for making XRPL EVM easier to use beyond the technical crowd 🌱 As XRPL EVM validators, we’re excited to keep supporting this ecosystem as it grows 🚀💪

Massive week @sedaprotocol

🌐 Tokenization is moving from narrative to real institutional infrastructure. In our latest article, we analyze the Beyond Cosmoverse conversation with Anina Milanović from the World Bank, and what it means for @cosmos, capital markets and the future of regulated digital assets. The key idea is clear: Tokenization is not here to replace traditional capital markets. It is here to upgrade them. In the article, we cover: 🔹 How Serbia built one of the earliest digital asset regulatory frameworks before MiCA 🔹 Why stablecoins pushed traditional finance to take blockchain infrastructure seriously 🔹 The three institutional requirements for tokenized assets: legal certainty, trusted infrastructure and secondary liquidity 🔹 Why emerging markets may have a unique opportunity to move faster 🔹 How Cosmos-IBC architecture, sovereignty and interoperability fits naturally into this new financial landscape For the @cosmos community, this conversation matters. If regulated financial assets start moving across digital infrastructure, networks like Cosmos can play a key role in making those assets interoperable, auditable and usable across jurisdictions. At Cumulo, we are validators in @cosmoshub and we believe this is exactly the type of long-term infrastructure narrative that matters for the ecosystem. 📖 Read the full article: 🇬🇧 English version: medium.com/cumulo-pro/regula… 🇪🇸 Spanish version: medium.com/cumulo-pro/regula…
