🚀 Cumulo weekly validator & infrastructure report

Summer may be kicking in on this side, but validator infrastructure doesn´t know about seasons: the best way to start the week is still by checking the technical work done in the last one.

Even when the market feels quieter on the surface, things remain very active under the hood.

🌌 @celestia / mainnet: submitted the on-chain signal for the v9 upgrade and continued tracking the quorum process for activation

🟡 @AvailProject / mainnet: migrated our validator to a new host, including session key rotation and full verification of block signing on the new environment

🟢 @quicksilverzone / mainnet: monitored the chain halt triggered by the team as an emergency response to an active exploit

🌌 @celestia / Mocha testnet: upgraded validator, RPC, and consensus nodes to celestia-app v9.0.4-mocha

🟠 @cosmos / testnet: voted YES on Prop #302, a text proposal on testnet

🌌 @celestia / Mocha testnet: upgraded the bridge node to celestia-node v0.31.3-mocha

🌌 @celestia / mainnet: upgraded the bridge node to celestia-node v0.31.3

🟠 @cosmoshub / testnet: voted YES on Prop #305 regarding funding for the public testnet program

⚡ @Starknet / mainnet + testnet: upgraded our RPC nodes to Juno v0.16.3, the new minimum required version ahead of the v0.14.3 protocol upgrade

At Cumulo, we treat validation as production infrastructure work: upgrade readiness, controlled migrations, governance tracking, incident response, and continuous operational verification.

It is not just about keeping nodes online, but about operating critical infrastructure with technical judgment, discipline, and traceability.

That is why we maintain our Activity Tracker: a public, JSON-backed record where we continuously document upgrades, governance votes, incidents, and operational changes in a transparent and auditable format.

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Static peer lists can be useful as a starting point, but they become outdated very quickly.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:

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 🤝

⚛️ 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:

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.

TL;DR 👇
Static peer lists get outdated fast. Cumulo Live Peers keeps checking which Cosmos Hub peers are reachable, stable and useful for node operators.

When you run a @cosmoshub node and connectivity starts failing, a static peer list is often not enough.

What you need in that moment is simple: peers that are actually reachable from the outside right now. Not peers that were visible from one node a few days ago.

That is why we built Cumulo Live Peers 🌐

A live peer checker for @cosmos Hub mainnet and testnet, updated every 30 minutes and available through both a public dashboard and API.

The idea is simple:

🔎 keep checking which peers are really reachable
🧹 filter out unstable ones
🛠️ give node operators a list they can actually use

How it works ⚙️
Every cycle, Cumulo Live Peers builds a candidate pool from several sources:

🟢 Our own Cosmos Hub node
🟢 RPC endpoints from validators in the ecosystem
🟢 Addrbooks and peer lists collected from validator resources
🟢 Peers contributed directly by operators

Then we test each candidate with 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.

Simple rule:
✅ reachable peers stay in the process
❌ unreachable peers are filtered out

Not just “more peers” 📡

The goal is not to publish the biggest possible list.
The goal is to publish a useful one.

Peers are scored based on recent stability, outbound activity, how many independent sources confirmed the same peer, geographic diversity.

This helps avoid lists full of random peers that may not help much in practice, especially when an operator is trying to recover connectivity quickly.
