Poolailler, stake pool

Poolailler is a Cardano stake pool operated in Europe. We operate our pool with a mix of on-premise and cloud infrastructures for optimal reliability.  We do not operate other pools and dedicate all our energy to Poolailler!

We provide high-quality, low fees stake service to our delegators.  Besides, we pay attention to our hardware power consumption to limit our environmental footprint.

Our personal mission statement

Further Decentralize Cardano

Our relays and block producer nodes are spread across three countries in Europe. Moreover, we rely on a mixed infrastructure. Half our relays run on servers that we fully own, while others are located in cloud environnement. This approach combines the full control of our servers, with the added redundancy of the cloud.

Reduce crypto-currencies environmental footprint

We love the blockchain technology and the groundbreaking applications relying on it. However, we are sensitive to the impact it may have on the environment. To limit our environmental footprint, we use low consumption hardware. All the servers we own use the latest generation of energy-efficient CPUs and SSDs, and have a thermal design power topping at 25W. We estimate our pool produces 40g of CO2 per day (source: https://www.eea.europa.eu/data-and-maps/daviz/sds/co2-emission-intensity-from-electricity-generation-3/@@view). We remain committed to further reduce our impact.


We pay extra attention to the hardware infrastructure we use. Our first concern is security and reliability. Nonetheless, we also calibrate our hardware to minimize power consumption.

First and foremost, we follow all official technical recommendations. Our private keys are store on a completely air-gapped laptop. We connected an extra relay on top of the two minimally required. We keep our systems up to date and regularly update our node using the latest Cardano software release.

Block Producer

Our Block Producer has 2 SSD mounted in RAID 1. We are going to add a second redundant alimentation soon. The producer is also protected behind a hardware firewall. It runs on an intel NUC.

Relay #1

Our first relay is located in Paris. Our relay run on a 8 Go. RAM Rasberry PI 4B. The board consumes around 5W. We use SSD storage.

Relay #2

Our second relay is located in the cloud (server is located near Munich). We use a 8 Go. RAM configuration with SSD storage.

Relay #3

We use an extra private relay for optimal reliability. Located in Palma, Spain. Having this private relay makes our pool virtually DoS-proof. The node runs on a intel NUC.


Cardano is a third-generation blockchain project and smart contract platform. It uses a Proof-of-Stake consensus that is provably secure as Proof-of-Work and at the same time, it ensures higher decentralization and scalability. The goal of the projects is to deliver a social and financial operating system that will provide digital financial identity to anybody who does not have one.


Most frequent questions and answers

Staking is a method of how to actively participate in network decentralization and governance. Instead of the electricity, that is used as a consumable decision resource in PoW, Cardano PoS uses native ADA coins. Thus, every holder of ADA coins is a stake-holder. A stakeholder can delegate coins to a pool and be rewarded.

By staking your ADA, you will assist the network with validating blocks and earn a passive return on investment, similar to a savings account.

Our “Fixed cost” per epoch is 340 ADA, this is the minimum allowed, as defined by the protocol parameters.

The margin is the percentage that the operator sets, to cover his operating costs. Every epoch, assuming at least one block is validated, the fixed cost + margin go to the pool operator, all the remainder is divided amongst our delegators. Each delegator reward will be proportional to his own stake.

“Live stake” is the current amount of delegated ADA to a pool

No, your funds are always safe on the blockchain! Basically, if you delegate, you register a certificate on the blockchain, that says, which stakepool your wallet belongs to.

That’s our bad, it’s a pun…in French. Basically, the word “pool”, sounds like the french word for chicken, “poule”. Then there’s “poulailler”, which’s a henhouse, and we liked the idea of keeping ADAs in a warm, cozy, and safe place. It’s funny in french, we promise!
