Custom monitoring graphs for xrp.ninja validator

Custom monitoring graphs for xrp.ninja validator

As you may know, my rippled validator runs on GCE. So I use stackdriver to monitor it. I created two custom metrics for it.

One metric is uptime with rippled version as a label. Here's a live graph for this metric. From this graph, you can easily tell what the current version is and when it was upgraded to that version. You can also correlate this with other graphs to see if new version may have caused certain changes in rippled behavior.
The other metric is the percentage of current uptime that rippled has been in a certain state. Normally the curve for "full" state should asymptotically approach 100. If it is not, then rippled is in trouble.

Information about this version can be found here https://ripple.com/dev-blog/rippled-version-0-81-0/.

There were some behavior changes after the upgrade:

How exactly is XRP going to work as a bridging digital asset?

Maybe this is obvious all along to some people. Anyway, I just figured this out. So I thought maybe it's worth sharing.

Previously I thought the bridging consists of two transactions, both on XRP ledger. One from fiat currency A IOU to XRP, the other from XRP to fiat currency B IOU.

Then I saw this:

So Miguel Vias said in the pilot they used liquidity on bitstamp and bitso. However it's seems the trading volume of XRP/bitso.MXN since the beginning of 2017 is so low that it's virtually no liquidity there. See this:

Then I realized, just like bitstamp, bitso has its own exchange and the liquidity there is much better.

So now it's clear to me there is another way for XRP to bridge cross-border payments. The originat…

You have to know these about ripple wallet and secret key

TL;DR:

It's possible to find out others' secret keys but it's so improbable that it's almost impossible. Make sure you have a good entropy source when generating your address/secret key.Use multi-sign https://ripple.com/build/how-to-multi-sign/
