Validate
the future

A staking team that kept two Kusama nodes in the Web3 Foundation’s 1KV programme. Today we validate on Ethereum, Kusama, Nibiru, Dymension and Celestia Mocha, and publish a transparency report for any Celestia wallet.

Our story

Built by
operators

Ledgera is the current name of Delega Pro, a staking team in crypto since 2022 and running nodes since 2023. Our first validator reached the active set on Kusama in 2024, and from March to November 2024 two of our nodes were in the Web3 Foundation's Thousand Validators Programme (1KV), until the Foundation closed it and replaced it with Decentralized Nodes.

Ledgera points the 1KV-style reporting at delegators. On Celestia it reads staking data for any wallet, and every morning it recounts what the largest wallets leave on the table: rewards nobody has claimed and stake still sitting on validators that left the active set. The Telegram bot watches commission, jailing and stake for its subscribers.

Today we validate on Ethereum, Kusama, Nibiru, Dymension and Celestia Mocha.

Spec sheet

What 1KV took

1KV re-checked every node each era and dropped anyone who broke a rule, so passing once was the easy part. Each line is a programme requirement and how we met it.

01

Hardware to the Polkadot validator reference

CPU
8 physical cores, 3.4 GHz or more, SMT off
Storage
NVMe, chosen for latency, not throughput
Memory
32 GB ECC
Network
500 Mbit/s symmetric

Cores picked for single-thread speed, because it decides how fast a node checks parachain blocks.

Before a server went live we ran the node's machine benchmark on it. The results go to the programme's telemetry, where a weak machine shows up straight away.

Polkadot validator requirements north_east
02

Location as part of the score

1KV geolocated every node from its telemetry and scored it higher for a less crowded country, region and provider.

We searched for servers that met the spec outside the usual European and US East Coast data centres. We run the same search for Celestia today.

Mocha validator and Fibre server: Jeddah, Saudi Arabia

03

Permanent telemetry

A permanent connection to the programme's dedicated telemetry. Every minute offline was recorded against the node, and a missed block or heartbeat in a session was logged as a fault.

Watching that by hand did not scale, so we wrote our own reporting in Element: per-era digests on block production, para-validator performance, commission changes and server drift. Other operators in the programme could subscribe to any validator, not just ours.

How the digests worked arrow_forward
04

Upgrades on a deadline

12 hCritical or high priority
24 hEvery other release

A standby node with its own name and its own session keys, upgraded first. Validation moved over by rotating session keys on chain, never by copying a keystore, so the same keys never ran on two machines.

Now

On Celestia we keep the same habits: hardware chosen against a published reference and benchmarked before use, servers in regions the network lacks, monitoring that never pauses, upgrades on a deadline, and keys that are never live in two places.

How the team splits the work

Signed entries

Entry 01

Our operators look after the servers, client upgrades, keys and signers, and take turns on call.

Every change to a node is planned and announced before it happens, and a key moves to a new host only after the old signer is stopped.

SignedOperators
Entry 02

Our developer builds the transparency report, the alerts bot and the install scripts, including the Fibre installer for Celestia validators.

The install scripts for operators are open on GitHub.

Commission and governance decisions are taken by the team lead and signed on a hardware wallet.
