Raftify is a Go implementation of the Raft leader election algorithm without the Raft log and enables the creation of a self-managing cluster of nodes by transforming an application into a Raft node. It is meant to be a more cost-efficient small-scale alternative to running a validator cluster with a separate full-fledged Raft consensus layer.

It is designed to be directly embedded into an application and provide a direct way of communicating between individual nodes, omitting the overhead caused by replicating a log. Raftify was built with one particular use case in mind: running a self-managing cluster of Cosmos validators.

Configuration Reference

The configuration is to be provided in a raftify.json file and must be located in the working directory specified in the second parameter of the InitNode method.

ℹ️ For Gaia, the working directory is ~/.gaiad/config/ by default.

Key Value Description
id string (Mandatory) The node's identifier.
Must be unique.
max_nodes int (Mandatory) The self-imposed limit of nodes to be run in the cluster.
Must be greater than 0 and must never be exceeded.
expect int (Mandatory) The number of nodes expected to be online in order to bootstrap the cluster and start the leader election. Once the expected number of nodes is online, all cluster members will be started simultaneously.
Must be 1 or higher and must never exceed the self-imposed max_nodes limit.
⚠️ Please use expect = 1 for single-node setups only. If you plan on running more than one node, set the expect value to the final cluster size on ALL nodes.
encrypt string (Optional) The hex representation of the secret key used to encrypt messages.
The value must be either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
Use this tool to generate a key.
performance int (Optional) The modifier used to multiply the maximum and minimum timeout and ticker settings. Higher values increase leader stability and reduce bandwidth and CPU but also increase the time needed to recover from a leader failure.
Must be 1 or higher. Defaults to 1 which is also the maximum performance setting.
log_level string (Optional) The minimum log level for console log messages.
Can be DEBUG, INFO, WARN, ERR. Defaults to WARN.
bind_addr string (Optional) The address to bind the node application to.
Defaults to
bind_port string (Optional) The port to bind the node application to.
Defaults to 7946.
peer_list []string (Optional) The list of IP addresses of all cluster members (optionally including the address of the local node). It is used to determine the quorum in a non-bootstrapped cluster.
For example, if your peerlist has n = 3 nodes then math.Floor((n/2)+1) = 2 nodes will need to be up and running to bootstrap the cluster.
Addresses must be provided in the host:port format.
Must not be empty if more than one node is expected.
