About Staking on Tezos
Tezos is a self-amending blockchain that launched as one of the first Proof-of-Stake networks in 2018, establishing one of the first ecosystems of node operators. Tezos differentiates itself through a sophisticated on-chain governance mechanism and formal verification of smart contracts.
Tezos uses a DPoS staking (known as ‘baking’ in Tezos) mechanism for its blockchain. In Tezos, there are validators and delegators. To participate in attesting to new blocks in Tezos without running a node, delegators can delegate their rights to a validator (‘baker’) such as Chorus One and will receive staking rewards in return. Chorus One pays out rewards every cycle when they are received.
Why Stake with Chorus One ?
The Chorus One infrastructure and surrounding processes are highly specialized to guarantee reliable and fault-tolerant operation of our nodes, as well as safekeeping of associated cryptographic key material.

Frequently Asked Questions
Tezo’s staking mechanism is known as ‘Liquid Proof-of-Stake’. This is because validators who are creating blocks must lock up a certain amount of Tezos to participate in consensus whereas delegators who have delegated their rights to validators are able to move their tokens around freely with no lock-up.
- Rewards: Bakers share rewards from baking (publishing new blocks) and endorsing (attesting new blocks) with delegators.
- Epoch length (cycles): Epochs in Tezos are measured in cycles. One cycle is 4096 blocks on the Tezos network, which equals ~4,096 minutes (or between 2 ½ - 3 days depending on network performance).
- Rolls: A roll is 8,000 XTZ. A validator can have either their own XTZ or XTZ that has been delegated to them. The more rolls a validator has in proportion to the rest of the network, the higher chance they will have to validate and attest new blocks.
- Snapshots: Snapshots are taken of all ‘rolls’ that exist in the network 16 times per epoch (every 256 blocks), which is around ~4 hours in real-time. A snapshot is like a photograph the blockchain takes of how many XTZ rolls belong to users at a given time.
- Validating rights: The right to publish a block in a given cycle is assigned to a randomly selected roll in a randomly selected roll snapshot. For example, the rights and priority a validator receives to publish the next block on Tezos is calculated by assessing all snapshots in a given cycle (~16 in a cycle) taken by the network 7 cycles ago (~3 weeks). This means that baking slots are assigned to validators ~3 weeks before their opportunity to publish a new block, making the staking mechanism backwards-looking.
- New delegation and/or re-delegation: Because of the abovementioned backwards-looking staking mechanism that Tezos uses, if a new delegation or re-delegation is made to Chorus, it would take ~21 days before a user would start receiving XTZ rewards.
- Lock-up: There is no lock-up period of XTZ, delegators are able to transfer their Tezos at any time whilst staking, ensuring their XTZ remain liquid.
- Payout: Tezos does not automatically pay-out rewards to delegators, we do payouts in the cycle when rewards are received.
- Slashing: There is zero slashing risk for delegators.
Proof-of-Stake (PoS) is an umbrella term for Sybil resistance mechanisms that use native cryptoassets as collateral to determine participation in the consensus process of a blockchain network. Staking enables token holders to earn a share of network income (e.g. from transaction fees) in return for placing their capital in escrow and helping to maintain the network.
In comparison to Proof-of-Work, where participants are rewarded for solving cryptographic puzzles in order to validate transactions and create new blocks, Proof-of-Stake relies on economic skin in the game (“stake”) in the form of network tokens.
Generally speaking, protocols that use some form of staking do so to enforce that the interests of participants are aligned with what the network aims to achieve. To learn more about the different types of staking, check out our framework here.
Validators in staking networks are nodes backed by collateral in the form of cryptocurrency tokens (“stake”). Token holders that stake (“stakers”) contribute to the network security by selecting trustworthy validators (“delegation”) and increasing the cost of a potential attack. They receive tokens as compensation for this in proportion to their stake backing (“staking rewards”). The size of these rewards is also impacted by additional factors such as network issuance rates (inflation), transaction (and sometimes storage) fees spent within the network, staking participation rates, as well as validator-specific factors such as uptime, commission rates, etc.

To ensure that the nodes (in Proof-of-Stake: validators) participating in a network behave as intended, many protocols enforce penalties if a node provably deviates from pre-defined rules. Penalties can mean that locked (staked) collateral in the form of tokens is taken from the balances of stakers backing that node. This is usually referred to as slashing. Other forms of penalties including excluding a misbehaving node from participating in the protocol, or temporarily lowering the rewards stakers receive. Such penalties pose the main risk of participating in staking. Read our Proof-of-Stake 102 post to learn more about other risks and tradeoffs to consider before getting involved in staking.
A critical component in the staking process is the need to lock tokens in escrow. In many networks there is an additional enforced delay that needs to pass before staked tokens can be withdrawn. This withdrawal delay is often referred to as the unbonding or lockup period.
One reason for these liquidity limitations is that protocols with staking need to ensure that slashings or other penalties can be enforced after the offense took place. If these limitations would not exist, a node could misbehave and instantly withdraw his stake, thereby avoiding penalties. In addition, lockup periods help with a variety of other goals like ensuring the safety of light clients, limiting validator turnover, and enforcing correlated penalties.
There are new designs emerging to mitigate the downsides of liquidity restrictions associated with staking through tokenization of staked positions, which is often referred to as liquid staking or staking derivatives. To learn more about these topics, check out our comprehensive liquid staking report.
Most staking network tokens are listed on various centralized exchanges such as Binance, Coinbase, Bittrex, Kraken, Poloniex, Huobi, etc. We recommend using Coingecko to figure out on which markets the token you are looking for is available. Staking with Chorus One will require you to move tokens from the exchange you bought them from to your personal wallet.
You can use our services and stake in a non-custodial manner by setting up a wallet and taking control of your private keys. If you bought tokens on a centralized exchange platform, this will mean you will need to withdraw your tokens to your own wallet. Refer to our staking guide to learn about wallet options and how to stake in a non-custodial manner.
Depending on your jurisdiction, staking reward taxation may vary. One approach that some industry groups are lobbying for is that staking rewards should be taxed only at the point when they are liquidated. Another view is that staking rewards should be accounted for when they are earned, which could be as often as every block! Many jurisdictions do not have clear guidelines yet on how staking rewards should be taxed. We are a founding member of the European Blockchain Association’s Proof of Stake Working Group (EUPoS) that seeks to educate European legislators about Proof-of-Stake to foster an innovation-friendly jurisdiction.
We recommend using services like CoinTracking, or if you are using a tax advisor, working with crypto taxation-focused firms like Pekuna in Germany to ensure you stay compliant while minimizing your tax burden.
To get a high-level overview, we recommend reading this article on the basics of staking and this post that covers the ecosystem of parties involved in staking networks. For other staking-related information, the recently launched Staking Academy is aggregating and curating high quality content and events in the space.
We are also producing a variety of content to keep you up-to-date on what is happening in the staking ecosystem:
