Some representatives hold a significant amount of voting weight. What about decentralization?

By looking at the weight distribution. Is nano really decentralized?

At the beginning of 2018, around 80% of Nano was delegated to official representatives. Aug 2019 it’s around 18%. As more and more services have been built around Nano, users have begun to distribute their voting weight among various representatives. It is now up to us (the development team and the community) to continue to make it easier for users to identify and select representatives to which they can delegate votes. While the current level of decentralization is not perfect, the trend towards it is very positive. Also, it is important to remember that Nano allows users to remotely redistribute their voting weight at any time, so the users of the network ultimately have full control.

The NWC desktop wallet and mobile wallet default to the official reps, for now. Other wallets, like the Ninjavault, suggest the best rep to the user based on a scoring model taken from mynano.ninja. While it’s always up to each user in the end what to choose, this method greatly helps to balance the weight. Nanocharts also has a feature to suggest a rep based on the same score. Feel free to join the #decentralise channel on Nano Discord to learn more.

For example, the Binance rep holds a large chunk as they are the largest exchange for Nano currently and many users do not remove funds from exchanges. It’s one entity/wallet that looks centralized but with many individual user accounts.
