About

CBROS is a small mission driven cardano pool based on powerful bare metal servers.

50 % of pool rewards goes to charitable donations - mainly to Médecins Sans Frontières - Doctors Without Borders.

Delegators rewards are not affected by donations.


Every delegator is most welcomed! We have NFT rewards for all delegators that will delegate more than 10 ADA for more than 3 epochs.


It's fair to mention that right now you can receive larger one-time rewards when delegating to our pool, but not in every epoch.

However the long-term average percentage of rewards is simillar for all pools (4 - 6 %) as you can see here.


We are:

  • Single Pool
  • With 50 % of pool rewards going to charitable donations
  • Supporting mainly Médecins Sans Frontières - Doctors Without Borders
  • With at-least 30 % of future pool income re-invested back to pledge
  • Patron of ADApools.org

NFTs



Unique delegators NFTs (mp4) and Atari Quotes NFTs (gif and mp4) were created in Atari BASIC programming language and although they may seem very old-school, we see some 8-bit poetics in them.


Nikon FM2 NFTs are unique analogue photos that were created by Martin just for fun.


As an reward for our delegators we distribute Atari NFTs after at least 3 epochs of delegation:


  • Every delegator - unique delegator NFT.
  • 10 - 100 ADA delegated - 1 of each atari quote - random color.
  • 100 - 1000 ADA delegated - 10 of each atari quote - random color.
  • More than 1000 ADA delegated - 20 of each atari quote - random color.

All NFTs here.

SPOs

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!


Martin


My family and my work as a medical doctor - 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.
