// 01 — About Cosmos Hub
What is Cosmos Hub?
Cosmos Hub (ATOM) is the foundational chain of the Cosmos ecosystem — a network of more than 70 sovereign blockchains connected through the Inter-Blockchain Communication protocol (IBC). Launched in March 2019, the Hub uses a delegated-proof-of-stake model where ATOM holders stake their tokens with validators who produce blocks and finalise consensus on behalf of the network.
The Hub's role has evolved beyond just being the original Cosmos chain. Through Interchain Security, ATOM now provides shared security to consumer chains like Neutron and Stride — meaning ATOM staked at the Hub also secures applications running on those chains, and earns additional rewards for doing so.
Cosmos Hub validators are limited to the top 200 in the active set, ranked by total stake. Staking with a validator outside the active set produces no rewards, so position matters. Commission rates and uptime track records are the main differentiators among the top-tier operators.
// 02 — Why stake with 01node
Receipts, not promises.
02
Zero slashing record
Across 40+ Cosmos-ecosystem mainnets we've operated, zero slashing events. Cosmos Hub included.
03
Active governance
We participate in every governance vote with published rationale. Our Yes vote on Proposal D (extending the validator set to 125, activating community pool) is on-chain since 2019.
04
ICS rewards passed through
ATOM staked with us automatically earns rewards from consumer chains via Interchain Security — no separate action required from you.
05
Horcrux threshold signing
Our Cosmos signing infrastructure runs on Horcrux 2-of-3 threshold signers behind YubiHSM-custodied keys. No single node compromise can produce a slashable signature.
// 03 — How to stake
Four steps, two minutes.
- 01
Open Keplr (or Leap, Cosmostation)
Install the wallet from keplr.app if you don't have it. Cosmos Hub is supported natively.
- 02
Click "Stake" on this page
The button deep-links to Keplr with the 01node validator address pre-selected on cosmoshub-4. No need to copy-paste anything.
- 03
Choose amount and confirm
Enter how much ATOM you want to delegate. Keep a small buffer for transaction fees and future actions. Confirm the transaction.
- 04
Rewards accrue per block
Rewards start the next block and compound at your discretion. Claim or restake any time — there's no cliff.
// 04 — Risks & trade-offs
What you should know.
Unbonding lock
If you decide to undelegate, your ATOM is locked for 21 days during which it earns no rewards and cannot be transferred or sold.
Slashing risk
Validator double-sign or extended downtime triggers protocol-level token slashing. Our zero-slashing record means we have never caused a delegator loss in 6 years of Hub operation.
Commission changes
Validators can change their commission via on-chain transaction with a 24-hour notice. Always confirm the current rate in your wallet before signing.
// 05 — Frequently asked
Cosmos Hub staking FAQ.
What is the unbonding period for Cosmos Hub (ATOM)?expand_more
21 days. During this window your ATOM is locked, earns no rewards, and cannot be transferred or sold. Plan your liquidity accordingly.
What's the current commission of 01node on Cosmos Hub?expand_more
5% — one of the lowest in the active set. The current rate is always shown live in your wallet before you confirm the delegation.
How safe is staking ATOM with 01node?expand_more
01node has operated on Cosmos Hub since the 2019 mainnet genesis with zero slashing events. Validator keys are held in dual-DC YubiHSM and signed via Horcrux 2-of-3 threshold signers — see /security for the full architecture.
Do I keep custody of my ATOM when I stake?expand_more
Yes. Delegation does not transfer your ATOM to 01node — your tokens stay in your wallet, you sign delegation messages with your own keys, and you can undelegate at any time. The validator only signs blocks on your behalf, never your tokens.
What rewards do I earn beyond the base ATOM inflation?expand_more
ATOM staked with us automatically earns rewards from Interchain Security consumer chains (e.g., Neutron). These accrue in the consumer chain's native token alongside ATOM rewards from the Hub itself.
How is my APR calculated?expand_more
APR depends on total ATOM staked across the network, current inflation rate (governance-adjusted), and your validator's commission. The figure on this page is a current estimate; actual rewards vary daily.

On Validator Setup: Seven Years Later
In June 2019 we published our validator architecture on Medium — YubiHSM dual-DC, VPN-only access, sentries per network. Seven years, forty mainnets, and zero slashing events later, here is what we kept, what we changed, and what we would do differently if we started today.
11 MIN READ→EngineeringWhy a Validator Is Not a Server
Five years ago a validator was a server. Today it is a cluster of signers, and the math is the entire reason solo operators still slash themselves. A focused walk-through of the 2/3 signing architecture, the slashing-protection check that runs before every block, and the key-sharding property that makes a single compromised node useless.
