VIZ is an DPOS blockchain with an unproven consensus algorithm (Fair DPOS with witness penalty for missing block).

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.
See documentation/building.md for detailed build instructions, including compile-time options, and specific commands for Linux (Ubuntu LTS) or macOS X.
Just want to get up and running quickly? Try deploying a prebuilt dockerized container. Both common binary types are included. 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
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 share/vizd/seednodes.
This same file is baked into the docker images and can be overridden by
setting VIZD_SEED_NODES in the container environment at docker run
time to a whitespace delimited list of seed nodes (with port).
