CB1 is a small node, that hasn't minted any blocks yet. Nevertheless, our goal is long lasting reliability. That's why we continue in our effort.

If you want to delegate a small amount of ADA to the CB1 pool you are most welcomed! However it's fair to mention that you can receive larger one-time rewards, but not in every epoch. If you want regular immediate rewards, we recommend you to choose some other pool with a bigger live stake. You can choose some pool from Mission Driven Pools [MDP] - you can earn ADA as well as support some meaningful charity project.

If you are a big whale, you are also most welcomed! We are a safe pool based on powerful bare metal servers with 100 % uptime. We are working on NFT rewards for you.

We are:

  • Single Pool
  • With 50 % of future pool income going to charitable donations
  • Without any income already supporting MDF and Prague NGO Automat
  • With at-least 30 % of future pool income re-invested back to pledge

Charitable donations

Martin already supports Médecins Sans Frontières and Prague NGO AutoMat on a regular monthly basis. You can find payment information below.

Every 3 months 50 % of pool income will be given to charitable donations. CB1 pool doesn't have any income yet.

We have informed both organizations about our plan (in the case of MSF we have contacted a local Czech organization).

At-least 30 % of pool income will be re-invested back to pledge.

30 % to MSF

Médecins Sans Frontières is an international humanitarian medical NGO of French origin best known for its projects in conflict zones and in countries affected by endemic diseases.

We are two brothers that grew up in former Czechoslovakia (today Czech rep.). Since our first Atari computer in the 80's, over the wild and free 90's, then over our pirate FM radio broadcasting in 2007, we are still enthusiastic in discovering new technologies.

We have been in touch with cryptocurrencies since 2013 and although living on different continents at the moment (Prague, Czech Rep.- Chicago, IL), we are cooperating together in building this pool. Why? Because it's our hobby, it's fun and it's an investment opportunity.

Be cool, bee free, be good!


My family and my work as a healthcare professional - these are the most fulfilling things in my life.

However my life wouldn't be complete without my hobbies - literature, music, yoga, bicycling, analogue photography...and many others. Since the 80's, when I shared an Atari 800 XE with my brother, I've been interested in computers. During my life in student's dormitory in the 00's I discovered the world of open source software and Linux and a few years later this experience led me to discovery of cryptocurrencies.

I see Cardano as the 3rd generation and ecologically sustainable cryptocurrency with a huge potential. I made some investments in ADA and right now I'm building a Cardano node.
