RE: 328 GRC bounty: notify users in Gridcoin wallet about important issues (new mandatory version, ...)
There are two good channels to send such message:
- alert protocol
- contract message
Note that the transaction does not need to be sent to each individual, wallet will pick up the contract even if sent to burn address.
Do you see any problems with this method of sending messages out to all active users?
At face value it appears like a very simple way to reach everyone who is active on the network, but your familiarity with the code base may yield a better alternative.
Alert protocol is perfect for this situations, it is fully implemented, except that the messages are not shown on the GUI.
Contract messages are not, but only a little work is needed to get them done. But Alerts are better: they work across forks.
