This is a lightweight daemon that allows mining to a local (or remote) karlsen node using stratum-base miners.
This daemon is confirmed working with the miners below in both dual-mining and karlsen-only modes (for those that support it) and Windows, Linux, macOS and HiveOS.

Shares-based work allocation with miner-like periodic stat output:
===============================================================================
worker name | avg hashrate | acc/stl/inv | blocks | uptime
-------------------------------------------------------------------------------
lemois | 0.13GH/s | 3/0/0 | 0 | 6m48s
-------------------------------------------------------------------------------
| 0.13GH/s | 3/0/0 | 0 | 7m20s
========================================================= kls_bridge_v2.2.0 ===
Multiple miners with significantly different hashrates can be connected to the same stratum bridge instance, and the appropriate difficulty will automatically be decided for each one. Default settings target 15 shares/min, resulting in high confidence decisions regarding difficulty adjustments, and stable measured hashrates (1hr avg hashrates within +/- 10% of actual). The minimum share difficulty is 64 and optimized for GPUs.
The grafana monitoring UI is an optional component but included for convenience. It will help to visualize collected statistics.
If the app is run with the -prom={port} flag the application will host
stats on the port specified by {port}, these stats are documented in
the file prom.go. This is intended to be use
by prometheus but the stats can be fetched and used independently if
desired. curl http://localhost:2114/metrics | grep kls_ will get a
listing of current stats. All published stats have a kls_ prefix for
ease of use.

Install go 1.18 or later using whatever package manager is approprate for your system, or from https://go.dev/doc/install.
cd cmd/karlsenbridge
go build .
Modify the config file in ./cmd/karlsenbridge/config.yaml with your setup,
the file comments explain the various flags.
./karlsenbridge
To recap the entire process of initiating the compilation and launching the karlsen dridge, follow these steps:
cd cmd/karlsenbridge
go build .
./karlsenbridge
Best option for users who want access to reporting, and aren't already using Grafana/Prometheus. Requires a local copy of this repository, and docker installation.
Install Docker using the appropriate method for your OS. The docker commands below are assuming a server type installation - details may be different for a desktop installation.
The following will run the bridge assuming a local karlsend node with default port settings, and listen on port 5555 for incoming stratum connections.
git clone https://github.com/karlsen-network/karlsen-stratum-bridge.git
cd karlsen-stratum-bridge
docker compose -f docker-compose-all-src.yml up -d --build
These settings can be updated in the config.yaml
file, or overridden by modifying, adding or deleting the parameters in the
command section of the docker-compose-all-src.yml file. Additionally,
Prometheus (the stats database) and Grafana (the dashboard) will be
started and accessible on ports 9090 and 3000 respectively. Once all
services are running, the dashboard should be reachable at
http://127.0.0.1:3000/d/x7cE7G74k1/klsb-monitoring with default
username and password admin.
These commands builds the bridge component from source, rather than
the previous behavior of pulling down a pre-built image. You may still
use the pre-built image by replacing docker-compose-all-src.yml with
docker-compose-all.yml, but it is not guaranteed to be up to date, so
compiling from source is the better alternative.
