I recently built a simple web app that estimates Cardano stake pools’ desirabilities. It might be useful for those who are interested in running a stake pool. Here is the github repo: https://github.com/cffls/cardano-stake-pool-desirability.
What is this project?
This project estimates desirabilities of Cardano stack pools, as well as rewards for stack pool leaders and stack pool members.
The calculation is based on cardano delegation design specification. A compiled pdf version is available here.
What is desirability?
Desirability of a stake pool shows how desirable it is for participants to delegate their stakes to. More desirable a pool is, more ADA rewards people will get by delegating to the pool.
Why should I care about desirabilities?
After Cardano enters Shelley (decentralization), people will be able to delegate their stake or run their own stake pools. Stake pools will be ranked by their desirabilities and be shown on Daedalus. Participants will be delegating their stakes to pools that have higher desirabilities for more rewards. Desirability is important if you are interested in:
- running your own stake pools
- experimenting your choices of cost and fee(margin) for your pools
What are “Myopic desirability” and “Non-Myopic desirability”?
Myopic desirability is proportional to immediate stake member rewards in the current epoch. In contrast, non-myopic desirability is proportional to long-term stake member rewards when a pool is saturated. Myopic desirability will be equal to non-myopic desirability in a saturated pool.
What is pool leader influence factor?
Pool leader influence factor is the degree of influence a pool operator’s pledged stake has on pool rewards. This factor is used in reward calculation to prevent sybil attacks, where malicious attackers can possibly create dozens or even hundreds of small pools to produce majority of blocks.
