What is Stake Delegation?

Cardano's willingness to assign or promise a stake is essential to its operation. ADA holders can earn rewards by delegating their stake to a stake pool run by someone else or running their stake pool.

What is Cardano Stake Delegation?

Ada held on the network Cardano represents a stake in the system, with stake size proportional to the amount of ADA held. The amount of stake assigned to a stake pool is the primary way the Ouroboros protocol decides to add the next block to the blockchain and earn a monetary reward. More and more stake is allocated to a pool of stakeholders (up to a certain amount), and the more possible it is to make the next block – and the benefits are shared with those who allocated their stake to that pool.

What is a Stake Pool?

Stake Pools Operators manage stake pools. They are network members with the expertise to consistently ensure a node's continuous uptime, which is key to ensuring the performance of the Ouroboros protocol and the entire Cardano network. With each position, the protocol uses a probabilistic process to pick a leader who is supposed to build the next block in the chain. The probability of choosing a stake pool node as the slot leader increases proportionately with the amount of stake assigned to that node.


When a stake pool node is chosen as a slot leader and a block is generated successfully, a reward is earned, which is shared with the pool proportionate to the amount every member has delegated. Stake pool operators may subtract their operating costs from the ADA they are given and determine a profit margin for the operation.



What is the delegation mechanism?

Delegation is the mechanism by which ADA holders assign to a pool of stakes the stake associated with their ADA. It requires ADA holders not having the skills or the ability to run a node to participate in the network and will be awarded in proportion to the amount of stake assigned.


Incentives preserve the integrity and protection of the environment and the Cardano network. Scientific research underpins the incentive mechanism by combining mathematics, economics, and game theory.


Many consider the Delegated Proof of Stake (DPoS) consensus algorithm a more efficient and democratic version of the previous PoS mechanism. PoS and DPoS can be used as a substitute for the consensus algorithm for Proof of Work since a POW process requires plenty of external resources by design. The Proof of Work algorithm uses a vast amount of computational research to create a distributed ledger that is static, decentralized, and transparent. PoS and DPoS, by comparison, need fewer resources and are more competitive and environmentally friendly by nature. The fundamentals of the Work Proof and Stake Proof Algorithms that preceded it must first be grasped to understand how Delegated Stake Proof works.

DPoS vs PoS

Although PoS and DPoS are identical in the stakeholder context, DPoS introduces a novel democratic voting mechanism, which elects block producers. Since the voters maintain a DPoS structure, delegates are encouraged to be fair and effective or voted out. Furthermore, the DPoS blockchain tends to be faster than the PoS ones in terms of transactions per second.


DPoS vs POW

Where PoS aims to fix PoW's faults, DPoS looks to streamline the block-creation process. Despite this, DPoS systems can rapidly handle large quantities of blockchain transactions. Today DPoS is not being used in the same manner as PoW or PoS. PoW is still considered the most reliable consensus algorithm and is where most money transmittance takes place. PoS is faster than PoW and possibly has more use cases. DPoS restricts staking use to the preference of block producers.


Its actual block production is predetermined, unlike PoW's competitive system. At block production, each witness gets a switch. Some people claim that DPoS should be considered a Proof of Authority system. DPoS differs substantially from POW and even PoS. Its integration of stockholder voting assists in deciding and motivating honest and efficient delegates.


However, genuine block production differs from PoS systems and, in most cases, grants a sophisticated performance in terms of transactions per second. The inclusion of voting by stakeholders acts as a way of evaluating and encouraging fair and successful delegates (or witnesses). The actual block output, however, is very different from PoS systems and shows higher performance in terms of transactions per second in the majority of cases.


What is Stake Pool Performance?

The efficiency metric measures how well a pool of stakes performs. This is given as a percentage and is determined according to how many blocks the stake pool has produced relative to how many it was supposed to make. For instance, if a pool provides only half the number of blocks for which it has been nominated, its output rating is 50%. This could be because the pool has a poor network connection or its operator has turned it off.


For a more extended period, performance scores have more meaning. In the current epoch, if a pool has not yet been selected to produce a block, its output rating would be 0 percent, even if it were likely to generate blocks later in the epoch. Its 100% performance ratings are only possible if pools generated more blocks than it was ever nominated to create.
