Blockchains need reliable ways for everyone on the network to reach agreement on the state of the chain. More granularly, that means that each transaction needs to be validated and added to a block, and that the ledger of transactions must match across nodes (or computers running its software) on the network. This process of validation, transmission, and agreement is called a consensus mechanism.
While there are many types of consensus mechanism, Proof of Stake (PoS) has become a dominant one, especially after Ethereum’s Merge event in September 2022. PoS networks comprise multiple participants, called validators or stakers, who earn the right to validate transactions by locking up some of their own digital assets as a “stake.” In return for processing transactions on the network, they receive a reward.
How does crypto staking work?
On Proof of Stake blockchains like Ethereum or Polkadot, users who wish to validate transactions can opt to run a node. This usually entails obtaining the proper hardware (sometimes simply a personal computer) and running the necessary software (or client) while connected to the internet. Successful nodes are reliable and are always connected to the network, validating transactions and securing the chain without interruption.
Validators must lock up a predetermined amount of crypto (called a stake) to prove they have “skin in the game” and therefore will act only in the best interest of maintaining the network.
To compensate validators for validating the blockchain, they are eligible to receive staking rewards in the form of the chain’s native cryptocurrency. The rules that govern these rewards—the percentage yield, how often they are paid out, which validators are paid when—vary among blockchains. Crypto staking is considered one of the most reliable ways of generating yield in the crypto space.
In an ideal world, validators are trusted to validate transactions correctly and to always be online. However, should they become bad actors or prove unreliable (like going offline or attempt to validate transactions that are nonexistent), many blockchains impose a penalty called slashing. This generally results in the loss of some or all of a validator’s stake and removes them from their position on the network.
Validator pools
Since faster, more advanced, and more popular blockchains demand increasingly complex hardware and software, running a validator node is not always easy for the average crypto enthusiast. Further, there may be a minimum stake which average participants may not be able to afford. On Ethereum, for instance, someone wishing to participate as a validator must deposit a minimum of 32 ETH into the chain’s designated smart contract.
To get around this limitation, staking pools are often created. These are either centralized services or automated protocols that allow any users to contribute smaller amounts of cryptocurrency to reach the minimum staking threshold on a chain. Staking rewards are then distributed among these services’ depositors based on their contribution.
What are the variations of staking?
Not every PoS blockchain works the same way. In fact, there are many types of PoS networks that aim to solve different problems. Three of the most common ones are:
- Proof of Stake (PoS) – Validators put up a stake and are chosen to process transactions, or create blocks, based on parameters such as the size of the stake or how long the validator has been staking their assets. The most notable example of a standard PoS is Ethereum.
- Delegated Proof of Stake (DPoS): Average blockchain users can delegate their coins to trusted validators who create new blocks on their behalf and receive a portion of the rewards for doing so. Cardano, TRON, and EOS are all examples of blockchains that use DPoS.
- Nominated Proof of Stake (NPoS): NPoS encourages stakeholders (called nominators) to vote for validators they trust to validate transactions. If the validator they voted for is picked, each nominator will share a portion of the reward with them. Polkadot is an example of a blockchain that uses the NPoS consensus mechanism.
Other variations, such as Leased Proof of Stake (LPoS) and Bonded Proof of Stake (BPoS), take the concepts of the three consensus mechanisms and tweak them in slightly different ways.
What are the risks of staking?
Staking is one of the most reliable ways to generate cryptocurrency rewards. However, in addition to the volatility inherent to cryptocurrency markets, there are a few unique risks associated with staking itself.
One of the downsides to crypto staking is that funds must be locked, meaning that those coins are removed from a user’s liquid assets and cannot be used for other purposes, such as in DeFi protocols or for active trading.
Additionally, staking sometimes requires a minimum lock-up period, and users may not be able to access their assets immediately upon the decision to stop staking. In other words, crypto staking carries the potential risk of opportunity loss.
Lastly, rewards may be subject to vesting, making them unavailable to users for a prespecified amount of time before they can be cashed out.
Staking with Bitstamp
When staking with Bitstamp Earn, customers maintain full ownership of their crypto assets. Bitstamp does not impose any lock-up periods or conditions for staking independently from the protocol, but lock-up periods and conditions may apply and vary depending on the PoS network.
Bitstamp acts as a service provider and charges a transparent commission of 15% on all rewards received from the underlying protocol. The estimated rewards rate reflects this commission.
Bitstamp offers a platform that allows you to stake your assets and earn crypto rewards for doing so.
Staking essentials
- Staking is a way for users to validate a network and receive cryptocurrency rewards in return.
- Whereas Proof of Work (PoW) systems use miners that expend energy to prove their on-chain engagement, Proof of Stake (PoS) systems host validators that lock up digital assets as their “stake,” earning them the right to collect rewards.
- Risks of staking include opportunity loss, market volatility, lock up periods, vesting of rewards, and slashing.
- There are multiple types of PoS systems that include Delegated PoS and Nominated PoS, lowering the threshold for user participation and democratizing network validation.
