An open-source, fair, and auditable Signum mining pool software where miners can choose their Share Model freely.
- PoC+ boost calculated by the pool using recent deadlines (no boost drops)
- Pool can be audited by API (all information is available to the public)
- Miners can set individually their share model
- Miners can set individually their donation fraction
- Miners can set individually their minimum payout
- Payouts by multi-out transactions with the current standard fee (variable)
- Support for multiple pool IDs (a primary and many secondaries)
Using this pool software, each miner can have a different share model, ranging from 0 % (solo mining) up to 100 %.
Further, miners can change their share model at any moment.
As an example, let's consider a miner with 10 TiB of capacity, and that this miner has chosen a share model of 80 %.
So, this miner actually has 20 % of his capacity solo mining (2 TiB) and 80 % going to the pool (8 TiB).
Let's also assume the pool has a total shared capacity (the sum of all shared capacities of all miners) of 160 TiB.
Since our miner is sharing 8 TiB he also has 5 % of the pool share (8/160).
Now, when this miner forges a block, the block reward (assumed to be 100 Signa here) would be distributed as follows:
As can be seen, when our miner forges a block, the reward is split between the shared fraction (80% in this case) and the forger fraction (20%) in this case. After that, the shared fraction is further split among all miners in the pool accordingly to their pool shares. In this case, the forger has 5 % of the shared capacity, so he also gets additional 4 Signa (5% of 80).
Just to simplify the share computations, in the above analysis the pool fees were assumed to be zero. Actually the pool fees are subtracted from the block reward before anything else. Additionally, each miner can configure a donation fraction, subtracted from their individual payments.
As already discussed, the amount each miner contribute to the pool share is a function of their share model.
In the following image, the schematics for a case where four different miners with 100 TiB capacity each have different share models:
Miners can configure not only the share model but also the percent they want to donate and the minimum payout. Configuration changes are accomplished by sending text messages to the pool.
Additionally, multiple pool IDs can be managed in a single pool. There is the primary ID, which makes the payments and receives the miner's commands and there can be multiple secondary IDs. Whenever a secondary ID forges a block, its balance is transfered automatically to the primary ID so it can manage the payments.

- Synced Signum node
- Java 64 Bits version 8 or 11
- MariaDB (Optional, but recommended for advanced users)
- Download The Latest Release
- Extract the zip file
- Configure
pool.propertiesto suit your needs - Run the jar file:
$ java -jar signum-pool.jar
You will need to wait some blocks before miners start to show their capacity
You need to modify the pool.properties file to suit your needs. Properties are explained in that file.
In addition to the above steps:
- Create a new MariaDB Database and create a user to access it
- Configure
pool.propertiesto use your database (server address, user, password, etc.)
Create a file named /etc/systemd/system/signum-pool.service with the following contents (edit the user and paths):
[Unit]
Description=Signum Pool
After=network.target
StartLimitIntervalSec=0
[Service]
Type=simple
Restart=always
RestartSec=1
User=user
WorkingDirectory=/home/user/signum-pool-v1.7.0
ExecStart=/usr/bin/java -jar /home/user/signum-pool-v1.7.0/signum-pool.jar
[Install]
WantedBy=multi-user.target
Now you should be able to start the service with:
sudo service signum-pool start
Similarly you can also stop the service with:
sudo service signum-pool stop
Additionally, it will automatically restart if your machine reboots.
Logs will be available by running:
journalctl -u signum-pool.service
Check the react-pool folder.
Before making customizations, be sure to visit that folder and read it's readme.md, discover tips that could give you a better development experience.
The software provides a public API that can be used to audit the pool. The same API is used by the website user interface.
The API will be available at your pool address:port, similar to http://testnet.btfg.space:9000/api/, with the following endpoints:
- http://testnet.btfg.space:9000/api/getConfig (returns the pool configuration details, fees, etc.)
- http://testnet.btfg.space:9000/api/getCurrentRound (returns the details of the current round/block)
- http://testnet.btfg.space:9000/api/getWonBlocks (returns the list of recently blocks won by the pool)
- http://testnet.btfg.space:9000/api/getMiners (returns the list of miners with recent valid deadlines)
- http://testnet.btfg.space:9000/api/getTop10Miners (returns the list with the top 10 miners)
- http://testnet.btfg.space:9000/api/getMiner/S-F6NV-CCGG-ER7W-99BRL (returns the details of a specific miner address)
All the capacities returned are in TiB.
- Gradle
- JDK 8 or superior
