The cheapest Cardano stake pool out there!

TECH pool is a bare-metal setup running on an ASUS PN51, powered by clean Norwegian hydro energy with one relay located in Sortland/Norway, TECH pool is maintained by an expert with ~10 years of experience in Linux OS server maintenance. Due to the minimal fixed fee of 170 ADA we are prohibided to set the pool fees any lower, we have therefore developed a custom software to automatically refund most of the fixed fee to the pool delegators (read more). The remaing pool fees will be split between server maintainace (67%) and donations to open source projects (33%).

Pool mission

We at TECH pool belives that open source projects deserves more credit, the truth is that open source projects are making the world a better place because of open source tools like e.g., Python and Tensorflow/PyTorch are used for cancer research, or Raspberry Pi used in education in Africa. Therefore, will we at TECH pool donate 33% of pool fees to open source projects, this could be projects like: Which projects that will receive donations will be voted on via the official TECH pool twitter account (@CardanoTech).

Refunds

It is not easy to attract delegators as a small pool operator and this is due to the minimum 170 ADA fixed fee and here is why.

The problem

At the time of writing (August 11th, 2024), the reward for minting a block on the Cardano blockchain is ~420 ADA and due to the minimum fixed fee of 170 ADA the actual pool fee per epoch with one minted block will be 40% (170/420*100). For stake pools big enough to mint e.g., 15 blocks per epoch the fixed fee will account for only ~3% in fees, but this will also require about 15M ADA in total stake, here is a plot that illustrates the impact of the fixed fee per August 11th, 2024. Actual pool fee with fixed fee

We at TECH pool belives that this is unfair for our delegators, so we have come up with a solution.

The solution

TECH pool will refund the fixed fee to its delegators. This can now be achieved because we have developed a Python based refund software that will automatically refund the fixed fee, delegators are not required to send their receiver address, all they need to do is stake with TECH pool and the refund will happen automatically when they receive the staking rewards.

How it works

The software will refund the fees proportional to the delegators stake, here is an example for a recalculated 3% fee with one block produced:

To refund: 640*0.97 - (640 - 340) = 320 ADA

Stake Refunded
Delegator 1: 100.000 ADA 94 ADA
Delegator 2: 40.000 ADA 38 ADA
Delegator 3: 200.000 ADA 188 ADA
Total: 340.000 ADA 320 ADA

Refunds that are less than 1.5 ADA will be accumulated, only once the total refund owed is above 1.5 ADA will the refund be sent. For example, if a delegator will on average receive 0.5 ADA per epoch, a refund of 1.5 ADA will be sent every third epoch. Paste your staking address (starts with 'stake...') below to find out what TECH Pool owes you in fee refunds.

PLEASE NOTE:
As the total stake of TECH Pool is currently 25.81M ADA, the total pool fee is currently below 3%, this means there will be no refunds. The refund mechanism will automacially get activated if the total stake drops below 15M ADA.

About

About TECH Pool

TECH pool is running on a ASUS PN51 (4 core, 32 GB RAM), a low-power computer drawing less than 45W of power - less than the power consumtion as a non-LED light bulb. TECH pool utilizes one relay, located in Sortland/Norway, the relay is rented trough a Norwegian VPS provider (www.deploi.no). By running both stake pool and relay in Norway we assure that (i) the whole TECH pool infrastructure is powered by 100% renable energy like hydro or wind and (ii) we aid the decetralization of the Cardano blockchain by avoiding popular VPS service like Amazon AWS or DigitalOcean. This infrastructure has prooven reliable as the pool has been online ready to mint blocks 24/7 since its deployment in 15th of April 2021.

For any questions you can contact us on X or Discord.
