Bitsign Federation blockchain is a special type of blockchain (PoA algorithm) that lets you use features of blockchain/smart contracts like notarization, timestamping, escrow/crowdsale contracts but with low to zero fee and costs. Also we've created an abstraction layer on top of our EVM based blockchain that can be used to integrate business models with blockchain and smart contract features using only RESTful APIs.
Bitsign Federation block explorer can be found here
Statistic explorer can be found here
To connect to Bitsign Federation Blockchain you need to use genesis.json for settings and initial conditions.

Also public nodes need to be queried to sync Federation blockchain to update to its latest state. You can use:
enode://a891225909f70a4ee3f40c1dac05da763fe0354d5f259922abf841db51706283d2957c09fc7266e5f4633583a34dbef3f38a769eb35551788740a06e387dfa2a@159.203.176.160:30303

Parity software can be downloaded here (version 1.9.x+ recommended)
For a quick run you can use the simple yet working config file to start Parity below: config.toml
For running Parity on Bitsign Federation an example command line can be:
$ parity --config config.toml
To Parity from a Docker container, you must clon this repository and then build the image with this command:
$ docker build -t bitsign-federation .
To persist the blockchain data you can create a named volume:
docker volume create --name=bitsign-federation-data
Then when the image building process finish, create the container with this command:
$ docker run --name=bitsign-federation-node \
-v bitsign-federation-data:/data \
-e NODE_NAME=some-name \
bitsign-federation --config config.toml
The NODE_NAME
environment variable is for set an references name for the
statistic explorer, you can choose whatever you want.
Note: If you want a quick run you can use config.toml
file, or you can replace --config config.toml
with the configuration you need.
