Nakamoto Coefficient Calculator

AIM

The aim of this project is to calculate the nakamoto coefficients for various popular blockchains.

Nakamoto coefficient is a way to calculate the level of decentralization in a particular chain.

Read this amazing messari report on operational decentralization of Proof-of-stake networks.

Disclaimer

Please note that the values should be interpreted with context since the same objective treatment is applied for all the chains included here, ie, we simply calculate:

nakamoto-coefficient: no of validators controlling 33% of the total network stake

Note that the threshold may be different for some blockchains, for example, 50%. So, I would suggest users to understand the context, cross-verify and examine the results. For any feedback, please join this discord.

Programming Languages

Golang

Steps to run

1. Build docker image

docker build . --platform=linux/amd64 -t xenowits/nc-calc:v0.1.4

2. Run the image

docker run --rm \

Notes

The actual logic is present inside /core. A goroutine runs every 6 hours which updates the nakamoto coefficients for all the chains.

Future Work

To add support for multiple other chains in /v1.
