UI awareness of blockchain state: head block age & participation rate

[roadscape]

Before the site broadcasts any tx, it needs to check the current participation level, and alert the user if participation is below 75% (and potentially not broadcast at all). This is a rare occurrence but it's important to catch it early.

This is needed to prevent users posting, voting, making transfers/orders, etc on forks.

fyi: Dan and Ben put this in the back end so the steemd node will reject the transaction. This would depend on the node that your talking too..

[roadscape]

It did not fully work, and it has been replaced by the simpler --max-block-age, which does not take into account the participation rate.

Details: https://github.com/steemit/steem/issues/345

If we could get --min-participation-rate added in steemd, we may not need anything on the UI side.

It would be good if the node rejected transactions if the conditions weren't right.

However, users should also know right away if something is wrong with the node, even if they're just reading the site.

• Show a notice if the head block age is more than 9 seconds old
• Show a notice if participation rate is below 80%

These conditions should be very rare, but it's important that users can see them (and let us know).

I guess this is still happening every once in a while..

This usually happens when I have leave the web page up for to long. A simple refresh of the page fixes the problem and allows me to post. but it would be a lot easier if that weird string of character didn't show up in the first place.

Is this still an issue, or can it be closed?
