Pool Score
The following table shows the operational results of JSP. Please note that the “pre-allocated block numbers” are allocated randomly by Cardano, so it is entirely based on luck. This does not affect ROS. ROS will converge to about 3.5% annually.
The important indicator to choose a delegation pool is the “block generation success rate.” Even if a lot of blocks are assigned by chance, if the server fails to generate the blocks, ROS will decrease. So far, JSP has operated and maintained its servers appropriately and has been able to generate almost 100% of assigned blocks. We recommend checking this “block generation success rate” when selecting a pool.

Operational Pool Basic Information
Maximizing Profit Returns
At our pool, we set the lowest possible cost and fee to ensure maximum profit returns for everyone. The pool operator can set the cost starting from 340ADA or more, but we have set it to the minimum value of 340ADA, and our fee is 0%, ensuring maximum rewards for those who delegate to us.
Thorough Examination of Updates’ Impact
Regarding cardano-node updates, we take the time to consider the effects before responding rather than immediately upgrading. This ensures that we can confirm there are no initial issues or inconveniences and safely proceed with the update.
Updates Performed Outside of Block Generation Time
We conduct updates outside of block generation time, avoiding any potential impact on rewards earned through block creation. Furthermore, we provide advance notice when conducting updates.
Constant Monitoring with Monitoring Tools
We constantly monitor the pool’s operational status using monitoring tools to ensure immediate action in case of any issues. We are committed to maintaining a stable pool operation to minimize any inconvenience to our users.
Using AWS(AmazonWebService)
We use AWS (Lightsail) for our server, providing high-speed communication and robustness. AWS has the highest security standards and is constantly updated with the latest security measures, ensuring swift response in case of any issues and peace of mind for our users.
Experienced engineers operate with transparency
Our stake pool server uses Linux, my most proficient OS. Additionally, I have five years of experience in operating and maintaining the business system of a major convenience store, ensuring stable server operation. We will report on the pool’s operational status and rewards payment through our website and twitter regularly.
