### How to upgrade your hypernode ###
There are currently many hypernodes stuck at height 76,170. A hypernode update has been released. All hypernode operators are advised to update their hypernode.

### Bismuth Hypernodes
The goal of the Bismuth Hypernodes is to provide added value to the network. Some basic masternodes implementations are merely staking or check for a ”ping” answer.

The **Bismuth Hypernodes** do operate on an entire different layer. They use a chain on their own, with no currency but metrics - Key Performance Indicators (KPIs) - instead. Both chains are loosely coupled and operate in an almost inde- pendent manner, with very different rules. 

The Hypernodes operate on a Proof of Stake (PoS) chain, with no mining and no competition between the Hypernodes. They observe and store their KPIs in the PoS chain. Since the Hypernodes are not part of the PoW chain, they do not add extra attack vectors.

Eligible Hypernodes are derived from immutable info stored in the PoW chain. Quality index and bad behavior from both PoS and PoW nodes is recorded, im- mutable also, in the PoS chain for later action.

**The independence of the two chains ensures:**
a/ It is way harder to manipulate the network, since it requires to forge both chains in very different ways.
b/ Bad actors and cheating attempts are recorded in an independent and immutable way. You cannot cheat unnoticed.

Bismuth may be the first crypto-currency to come with an integrated but in- dependent KPIs dedicated side chain that monitors the network and ensures actors fair play.
