VIZ is an DPOS blockchain with an unproven consensus algorithm.

Code is Documentation
Rather than attempt to describe the rules of the blockchain, it is up to each individual to inspect the code to understand the consensus rules.
Just want to get up and running quickly? Try deploying a prebuilt dockerized container. Both common binary types are included.
Dockerized p2p Node
To run a p2p node (ca. 2GB of memory is required at the moment):
docker run \ -d -p 2001:2001 -p 8090:8090 --name viz-default \ viz-world/viz-world docker logs -f viz-default # follow along
Dockerized Full Node
To run a node with all the data (e.g. for supporting a content website) that uses ca. 14GB of memory and growing:
docker run \ --env USE_WAY_TOO_MUCH_RAM=1 \ -d -p 2001:2001 -p 8090:8090 --name viz-full \ viz-world/viz-world docker logs -f viz-full
A list of some seed nodes to get you started can be found in documentation/seednodes.
This same file is baked into the docker images and can be overridden by
VIZD_SEED_NODES in the container environment at
time to a whitespace delimited list of seed nodes (with port).
How to produce blocks
The produce blocks algorithm used by VIZ requires the owner to have access to the private key used by the account.
./vizd --witness="accountname" --seed-node="126.96.36.199:2225"
