Stake Harmony with Kiln, enterprise-grade staking

What is Harmony?

Harmony is an open blockchain built to be fully scalable and energy efficient. Through a sharding-based blockchain, the protocol achieves a 2 seconds transaction finality for very low fees. Harmony also has a built-in Zero-Knowledge Proofs functionality enabling research and innovations around privacy.

How is Harmony Delegated Proof-of-Stake implemented?

Anyone can delegate some ONE tokens to a validator that participates to the consensus of the Harmony. The more stake assigned to the validator, the more often it is chosen to write new transactions, and therefore the more it earns rewards.

Why should you stake your assets?

Staking generates one of the safest and most predictable ways to get rewarded in the crypto space. It is the most natural reward feature in crypto as the value originates from the blockchain native currency inflation and a share of transaction fees. You help secure the network and earn rewards by staking your ONE.

If you do not stake, your assets token share will be diluted among other people’s tokens that are being staked and accumulating new tokens into the network.

You can stake your ONE as well as other (d)PoS cryptocurrencies to:
  • Put your treasury to work
  • Diversify and earn, while contributing to blockchains decentralization
  • Bring new opportunities by enabling your users to earn staking rewards

Stake Harmony FAQ

What does Proof-of Stake mean?


Proof-of-Stake (PoS) is a type of consensus mechanism used to validate cryptocurrency transactions. Through PoS, validators can contribute to the block production of a chain while keeping environmental concerns to a minimum, which is becoming an increasingly large issue in Proof-of-Work, the consensus algorithm used in Bitcoin.

By staking capital rather than energy, validators risk losing a portion of their value and future potential for staking by misbehaving while creating blocks. This incentivizes collaboration and minimizes malicious activity in the consensus process.

What is the difference between PoS and dPoS?


Both are consensus algorithms, helping to democratize participation in securing a blockchain. DPoS is an iteration of PoS combining real-time voting with a system based on reputation to reach consensus across the blockchain. Voting power is still determined by how many tokens they have however.

When will I receive ONE rewards?


ONE rewards are issued every block in the same ONE address you are staking with.

Does interest compound when staking ONE?


ONE rewards are not compounded. You have to claim rewards and add them to your stake to compound ONE tokens.

What are the risks associated with staking ONE?


Harmony implements a slashing mechanism. This includes downtime for validators and their delegators and for nodes that attempt to vote on two separate attestations at the same time. Slashed validators will add bonded tokens to the staking pool.

Slashing also occurs if Harmony’s Proof-of-Stake generates an invalid hash.

The main risk on the Harmony blockchain as of today is downtime. To prevent this risk, you can outsource your blockchain services to a dedicated infrastructure provider such as Kiln, which has a 99.95% effective uptime. You can now focus on your business while our experts take care of the infrastructure.

Is there a minimum and maximum amount to stake for Harmony?


There is no minimum and maximum to stake ONE.

Do I maintain custody of my ONE tokens? Is ONE staking non-custodial?


While you may maintain self-custody of your staked ONE (ideally using a Ledger hardware wallet), you may also choose a third-party custodian to control the withdrawal of your staked ONE (i.e. Fireblocks).

What is the lockup period to stake Harmony? When can I unstake and withdraw my ONE?


The maximum lockup period for Harmony is 1 epoch, and one epoch is ~18h.

How do rewards and penalties work?


For every slot, the validator is expected to sign attestations. If submitted attestations are good, the validator receives rewards, otherwise it receives penalties. In case the validator is offline it will also receive penalties.

What is the average block time on Harmony?


The average block time on Harmony is 2 seconds.

What is a Gross Reward Rate (GRR) and how is it different from a Net Reward Rate (NRR)?


In the context of Proof-of-Stake blockchains, the gross reward rate (GRR) refers to the total or gross amount of rewards earned from staking before deducting any fees or expenses. This is a reward rate that fluctuates with the operations of the protocol and the performance of validators, it is not set by Kiln. The net reward rate (NRR), on the other hand, takes into account the deductions or expenses, providing a measure of the actual rewards received after subtracting fees or costs.

Gross Reward Rate (GRR) may change over time and vary depending on the open source blockchain protocol code. In addition, fees might be deducted from the gross effective rewards earned.
