Question about the wallet:
So, in the more recent wallet releases there's been a graph on the overview tab of Stake Weight vs. Blocks. Can we get some explication of this indicator? How does that graph relate, mathematically, the amount of HYPER you own vs. how tall the HYPER blockchain is?
The graph just shows your staking weight on the network at a particular time. The higher your stake weight on the graph at any point in time, the higher your stake weight and therefore the higher your chance of minting a new block at 5% monthly proof of stake interest with your coins. Stake weight itself is calculated with the number of HYPER in one input you have trying to stake (the more coins in one input the higher your stake weight) as well as their coin-age (anything over 24 hour coin-age leads to higher stake weight). So if you have a large amount of coins, say 10 000, and you do not open your wallet for a month, as soon as you open it you will get your 5% monthly stake straight away as you have a very high stake weight both from number of coins in the input (10 000 which is quite high) and from very old coinage (one month when minimum staking is 24 hours). The graph will shot up in this scenario.
If you leave the wallet open all the time the graph will go up and down within a range, as it is low just after you have staked and is higher just before you stake which is when you have the highest stake weight possible.
As for the exact formula I would need to check with Palm Detroit our developer who added the stake weight graph into the latest versions.
