What is the minimun ADA required to stake pool?

Does anyone know if there is a minimum requirements of ADA for a stake pool.

What will be consider a Heavyweights, Medium or Solo stake pool?

Thanks in advance. :+1:

Check out the official channel at https://staking.cardano.org/faq/

To operate a public competitive stake pool, the owners of the pool have to pledge ada to their pool. The details of this are covered in the documentation on staking incentives. No minimum amount of ada is required to run a pool or to delegate to a pool, though you do need some ada to pay the transaction fees.

Thanks for your response @Adaizen, I just checked the link you just reply.

I do have more questions regarding the information posted on the Incentive and Staking webpage.


“This policy should prevent stake pools from growing too large, ensuring there is decentralization of users”.

How this is calculated?

“Attacks like selfish mining or block withholding cannot work, because the pools are fenced off from each other. The actions of one pool only affect its own rewards”.

What pool actions are they referring to? in order to affect its reward.


“As a consequence, there will be a predicate that, looking at the slots a given stake pool was elected for as leader and the number of blocks it actually created, will decide whether the stake pool is eligible for its share of the rewards pool”.

How this is calculated, is there an equation for that? in order to decide if a stake pool is eligible

“This predicate might also not be all-or-nothing, but instead award a certain percentage of available rewards based on adherence to the protocol”.

“The way the distribution of funds works means that there is no competition between pools: There is nothing one pool can do to increase its rewards by decreasing another pool’s rewards”.

“Note also that the way distribution of funds works implies that there is no competition between pools: There is nothing one pool can do to increase its rewards by decreasing another pool’s rewards”.

“Neither is there any incentive for any pool to sabotage another pool’s work”.

“The predicate cannot be as simple as “created at least x% of the blocks it was supposed to”, because this could lead to nobody being online towards the end of an epoch”.

Also, How the protocol comes up with a percentage?
Is it a gambling process randomly assigned to a Stake Pool?, the number of ADAs at stake?, or as in some way as ‘Bitcoin Mining’, the proportion of the reward is equivalent to the hardware power in use, to be a factor in the eligibility process?

If the selection, is a gambling process, will having multiples pools across different locations will increase the probability of eligibility?

Once again, Thank you in advance for your consideration.

Cardano’s reward sharing scheme

k = 100 desired pools

k pools can move between stages:

  1. Growth
  2. Stabilization

Growth stage <–> Saturation point <–> Stabilization stage

The saturation point is that middle ground between the two stages.

Saturation Point = k / k = 1

k is both a number of desired pools and the distribution of rewards over same number k

Saturation Point = 100 / 100 = 1

Using their example of two pools out of k (100)
A = 0.3%
B = 1.2%

IF a pool is less than or equal to 1 then rewards to pool are proportional to stake
Else a pool is greater than 1 then rewards are 1

Pool A can grow 0.7% more where as pool B should have -0.2% of its delegates move to a pool in growth phase.

Actions that are adversarial in nature.

Any pool that does not fulfill its slot will lower the rewards of all pools, not just theirs.



@Adaizen , thank you very much for your time! Appreciate it.

Your article just answer what I was looking for.
