Stake Pools and Delegation
How staking works in Cardano without lock-in or risk of loss.
What is a Stake Pool?
To participate in block production, the Ouroboros protocol must be executed. This requires reliable servers, good internet connections, and technical knowledge. Not every Cardano user wants to or can operate such a node around the clock. For this reason, there are so-called Stake Pools.
Stake Pools are server nodes operated by community members (Stake Pool Operators, SPOs). They aggregate the 'stake' of many different users to increase the probability of being selected in the Ouroboros lottery and validating blocks for the network.
Delegation: Liquid & Secure
Cardano's staking system is one of the most user-friendly in the entire crypto industry. When you stake your ADA, you do so via delegation to a stake pool. The following outstanding characteristics apply here:
- Non-Custodial (Security of Funds): You never transfer your coins when delegating! Your ADA always remains 100% in your wallet and under your control. You merely delegate the "voting power" of your coins to the pool. The pool operator has absolutely no access to your wealth.
- No Lock-in (Fully Liquid): On many other blockchains, your coins are "locked" during staking and become unavailable for weeks. In Cardano, there is no lock-in. You can send, sell, or use your delegated ADA immediately at any time. The network simply takes an automated snapshot of the current state at regular intervals.
- No Slashing (No Penalties): In systems like Ethereum, you can be penalized ("slashing" - loss of coins) if the server you delegated to misbehaves or goes offline. In Cardano, there is no slashing. In the worst case, if the pool is offline, you simply receive no rewards for that period, but you never lose your invested capital!
Rewards & Pool Metrics
In return for your contribution to network security via delegation, you are regularly compensated. These Rewards (staking rewards) are automatically distributed directly into your wallet every 5 days at the end of an epoch.
A healthy stake pool thrives on transparency. SPOs can define:
- Pledge: Their own ADA that they invest in the pool themselves as a proof of confidence.
- Margin Fee & Fixed Fee: The percentage share and the fixed portion (usually 170 or 340 ADA per epoch) of the block rewards that are held back by the pool operator as server costs before the rest is distributed among the delegators.
