When I look at this :
https://chainz.cryptoid.info/phr/#What does the "Value Out" column mean?
Is that amount of phore in the wallet which found the block?
eg: I have 500 phores, now if I hit a pos block and successfully win some coins, will my staked 500 phores show up on that list as "value out"?
The value out contains all transactions in a block, including generation, fees, and any transaction sent.
Look at this block for example:
https://chainz.cryptoid.info/phr/block.dws?134559.htmThe first line shows 6.99 PHR generated (2.69 POS + 4.2 MN).
The second line shows the POS winning pile (829.99 PHR => 832.79 PHR)
and the MN winner (4.2 PHR). Note that the value out in the second line shows the input pile + POS reward + MN reward, even though POS and MN rewards went to different addresses.
The third line shows a transaction, I believe 70 PHR were sent and the remaining 243 were returned to a change address, but it might be the other way around, 243 sent, 70 returned, not sure.
Either way, the value out shows 1151, the total of all the above.
For your example, if you had 500 PHR hit the POS reward
and there was no other transaction in this block, it should show up as value out 506.99, your 500 + your 2.69 POS reward + the 4.2 MN reward for this block. If there were other transactions as well they would all be added together with your 506.99 for the value out.
