Key Technical Parameters
Pledging Mechanism
There is no required minimum pledge amount. However, pool operators can optionally pledge some or all of their stake to their pool to make their pool more attractive. The higher the amount of ada pledged, the more rewards the pool will receive, which will attract more delegation. The a0 protocol parameter defines the influence of the pledge on the pool reward.
Saturation Parameter (K)
Saturation indicates that a particular stake pool has more stake delegated to it than is ideal for the network. Meanwhile, k is the targeted number of desired pools. Once a pool reaches the point of saturation, it will offer diminishing rewards. The saturation mechanism aims to prevent centralization. First, it encourages delegators to delegate to different stake pools. Second, it incentivizes operators to set up alternative pools so that they can continue earning maximum rewards. Saturation, therefore, exists to preserve the interests of both ada holders delegating their stake and stake pool operators. It also prevents any single pool from becoming too large.
Desirability Index
To calculate the desirability of a pool, take the pledged owner’s stake, costs, and margin. Then combine them with an influence from saturation and pool performance. Daedalus and Yoroi will use this number to rank pools. It also indicates how ‘desirable’ or ‘attractive’ the pool is to potential delegators.
Decentralization Parameter
This tunable parameter will control the ratio of slots the federation of nodes creates compared to the slots stake pool nodes create. It will apply at the beginning of Shelley’s deployment to the mainnet. Note that during this transition period, operating stake pools will receive all rewards and the federated nodes will receive none. Implementing the decentralization parameter allows the network to stabilize.
WHAT IS STAKING?
WHAT IS STAKING?
Ada held on the Cardano network represents a stake in the network. The size of the stake is proportional to the amount of ada held.
Also, the ability to delegate or pledge a stake is fundamental to how Cardano works.
An ada holder can earn rewards in two ways. First, they can delegate their stake to a stake pool that someone else runs. Second, they can run their own stake pool.
The Ouroboros protocol chooses who should add the next block to the blockchain. That stake pool also receives a monetary reward for doing so. The primary factor in this choice is the amount of stake delegated to a given stake pool.
The more stake delegated to a stake pool (up to a certain point), the more likely it is to make the next block. Everyone who delegated their stake to that stake pool shares the rewards that it earns.
WHAT IS A STAKE POOL?
WHAT IS A STAKE POOL?
Stake pools may be either public or private. A public stake pool is a Cardano network node with a public address. In addition, other users can delegate to it and receive rewards. In contrast, private stake pools only deliver rewards to their owners.
A reliable operator runs each stake pool. That operator is an individual or business with the knowledge and resources to run the node on a consistent basis. Ada holders can delegate to public stake pools if they wish to participate in the protocol and receive rewards. This works for holders who do not wish to operate a Cardano network node themselves.
The more stake delegated to a stake pool, the greater chance it has of becoming a slot leader. Each time the pool becomes a slot leader and produces a block that the blockchain accepts, it earns a reward. The stake pool operator and stake pool delegators share these rewards.
Extensive research and development has gone into ensuring a fair, competitive marketplace. This marketplace proportionately incentivizes participation and rewards the investment of time, energy, and resources. The key technical parameters influencing stake pools and the rewards they receive are:
How Do I Set Up A Cardano Stake Pool?
It’s important to remember the role of a stake pool operator: to ensure reliable, 24/7 operation of a network node.
In addition, as a stake pool operator, you have a responsibility to the ada holders who delegate to you but also to the health of the network itself. This requires a stable and reliable network infrastructure. Ideally, it also requires system operation and server administration skills along with experience in development and operations.
Anybody can learn how to operate a stake pool. However, it requires a degree of technical familiarity and knowledge.
Cardano Stake Pool FAQs
How much Can i Make? What is the potential profit?
You can use the rewards calculator to get an idea of the rewards you will earn. Note that the calculator produces only reward estimates. Also, do not consider them definitive or a guarantee of reward amounts. Over time, parameters may change in ways that could affect reward margins. Amounts calculated are therefore subject to change, but they represent a realistic and sensible level of return.
What skills do 'Stake Pool Operators' Need to Have?
As a stake pool operator, you will typically have:
- Operational knowledge of how to run and maintain a Cardano node on a 24/7 basis
- System operation skills
- Experience of development and operations (DevOps)
- Server administration skills (operational and maintenance)
Which operating system(s) does Cardano (ADA) support?
We support Linux, Berkeley Software Distribution (BSD), Mac, and Windows platforms. Each platform needs one of the following versions:
- Linux (2.6.18 or later)
- BSD (NetBSD 8.x and FreeBSD 12.x)
- OSX (10.7 Lion or later)
- Windows 10
Private Pools and Delegators
Can I run a Private Stake Pool?
Yes, this is technically possible. You can achieve it by registering a stake pool and setting the operator rewards percentage to 100%. Then anybody that delegates to your stake pool will not receive any rewards. This will disincentive delegators from delegating to you. However, it gives you the ability to stake your ada and singly reap the rewards, while testing your stake pool operations.
How Can I Attract ADA 'Delegators' to my Pool?
The network will rank stake pools by performance, so it is important that your stake pool is online and active when the network elects it to create blocks. Stake pool operators can also pledge – through delegation – their personal stake to their own pool. In addition, when operators provide a pledge address while registering the pool, users will be able to see which pools their operators have pledged to. Additionally, stake pool operators can inform users about:
- Security: details of how the operator has secured a stake pool against hackers
- Team: information on the operator’s team and experience in managing stake pools
- Communication and social media: regular updates and support for delegators
- Website: stake pool information and marketing
Pledging, Bugs and Rewards
What is Pledging?
Pledging refers to stake pool owners’ ability to delegate personal stake to their pool. There is no required minimum pledge amount. However, pool operators can optionally pledge some or all of their stake to their pool to make their pool more attractive. The higher the amount of ada pledged, the more rewards the pool will receive, which will attract more delegation. The a0 protocol parameter defines the influence of the pledge on the pool reward. Read more on pledging on the IOHK blog.
How will ``bugs`` effect my Stake Pool?
Stake pool operators will need to be available as much as possible to respond to any network or performance alerts. Also, it is important that pools ensure their node is running the latest software.
Characteristics of a ``good`` stake pool?
The network ranks stake pools based on their overall performance and other key information. The performance metric is a calculation based on the number of blocks the pool had to create compared with the number of blocks it actually created. In addition, the network records it over time. We recommend that ada holders also do their own independent research when choosing where to delegate their stake.
Are Rewards ``guaranteed`` ?
You can earn rewards for delegation if you delegate to a stake pool that shares rewards. Nobody can guarantee the amount you earn, which will ultimately depend on the stake pool, the amount of rewards shared, and its performance. Note that rewards only begin from the end of the epoch in which you delegated the associated stake.
