Steemdb is a good template. It fits a lot of information into a small space. I'll try to keep more data in table form going forward hopefully making it more convenient to use. Thanks

Nice! I will definitely be using this to monitor my seed node and other witness related activities.

Hey again,
Thanks for all of the great feedback, and sorry for the delayed response. I have been working on a bare bones setup to start monitoring and reporting some of the metrics you suggested and switching servers took a little longer than expected. If you want to check it out here it is.

It should be easier to identify the individual feed now that the selected witness is highlighted. Also it now shows recently missed blocks for the last 1, 6 and 24 hours for the selected witness. It only has about 12 hours worth of data right now, so I limited the outputs to reflect that. I think moving forward it makes sense to keep one page as a sort of overview/recent activity(missed blocks, feed history, latency?, other info) and have some other pages for more detailed or historic information. That being said I do plan to eventually add some tables in order to monitor multiple witnesses at once. Also I'm open to locating it wherever it might get the most use, so whenever it seems presentable enough I'd be happy to move it. So, please let me know if you have any additional thoughts, suggestions or criticisms and thanks again for checking it out.

My concern with the idea of paying interest to USD is that it incentivizes activity which hasn't been proven to generate profit for the Dex. While the idea the locked collateral reduces supply makes sense, I think it provides minimal price support as those creating the assets are already in for the long haul and aren't any more likely to hold because of their leveraged position. If any thing thing these people are now less likely to hold as they now the chance of selling against their will from a margin call. In addition if you view the amount to of bitasset as somewhat fixed (finite number of shorters with finite amount of funds) then increased holding of bitassets puts additional strain on those shorters in their efforts to provide liquidity.

IMO the end goal of any new incentive should  be to make the Dex more profitable by increasing the number of actions and fees generated. I think increases in the speed which USD changes hands would be more beneficial than an increase in the amount held. I think the increase in liquidity lately has been encouraging and I think an incentive be to increase liquidity and market making might be a better choice. Just my thoughts. I don't want to discourage the pursuit of improvement, but at the same time wanted to express my concern.

Hi everyone,

I have working on some interactive graphs for data pulled from the blockchain  and I was hoping to get some feedback from the community.

First, do you think these types of graphs could be useful? They are not quite as real time as a block explorer(updated daily or maybe hourly), but I think they could be useful for specific datasets 

Second, are there specific topics which you would like to see displayed? One of my thoughts was to graph different witness performance metrics as that has been a recent topic of discussion, but if there were other topics more beneficial for new users, that might be better to focus on.

Any comments or questions are appreciated. Thanks

They made some posts on steemit a few months back. I think they might have another forum they use. You may want to start here.

Hi everyone, another update,

A little over a week ago I participated in the stress test and I am happy to say witness lafona2 processed over 100000 transactions and 500000 operations during the two hour stress test. It was capable of producing blocks with more than 3000 transactions in them or 1000 txs/sec, not bad for an Avoton based server. That being said I am still looking through the data, to better understand why blocks were missed and how to optimize the setup for the next run. If you would like to look at or  play around with some of the data, I made some charts which you can check out here. During the stress test, I was also runnning a node for transaction spamming purposes, but I do not currently have any data on that yet.

In addition to that I have been working on a graph of the price feed data from the blockchain, as that has been a pretty consistent discussion recently. It is still very much a work in progress(no historical data, only USD, etc) but if it is helpful I can work on adding other bitassets and including older data. Eventually I would like to be able to unpublished price feed data to help with testing of new witness setups or feed scripts, but that is still a little ways away. Please let me know if you have any thoughts or suggestions.

Feed History

The primary and backup witness nodes on the bitshares mainnet are now hosted in Paris and Amsterdam and and are running on 8 core Intel Avoton 16 gb machines.
Thanks for you time and attention.

The key difference lies in whether you are trading a UIA(user issued asset, open.btc, trade.btc, etc) or a (MPA market pegged asset/smartcoin, bitUSD, bitBTC, bitCNY). UIAs would carry similar counterparty risk to a normal exchange, however the MPAs are backed by on chain collateral and are thusnot subject to that risk. Depending on the market, you could have similar counterparty risk if it is UIA:UIA, half the risk(UIA:MPA) or none of the risk (MPA:MPA).

This sounds really interesting. Does the arbitrage opportunity always go the same direction? If not we could try to start the USDT:bitCNY market and remove one of the intermediate steps for those willing to take advantage of the arbitrage opportunity. Anyways it looks like the USDT:bitUSD market is pretty healthy now and hopefully people will start to use it more.

Hi Everyone,
Just wanted to give a quick update. I recently added a seed node at I had removed the old node after being voted out for an extended period, but with more affordable hosting I plan to keep this one up despite currently being on standby.  I am also currently running a two witness nodes(one as a backup) and should have price feeds set to go if I am voted in again. I also have a node running in the testnet ready to use as a witness or a spammer. Thanks for your time and please feel free to vote for delegate-1.lafona. Thanks

Hi guys, Thanks for the kind words. It looks like they worked. I have my feeds back up and running and will try to get a seed node up and added soon. Hope I don't disappoint. :)

And why does the website need to keep our private keys? That defeats the very purpose of private keys. And why do I need facebook to register? How can I create an account without facebook?
I dont believe the website keeps your private keys. From my understanding, the private key works the same way on steemit as it does with openledger. It is used to sign a transaction locally on your computer and then transmits the signed transaction. If you are concerned using your bitshares key, you can generate a new private key using suggest_brain_key in either the steem or bitshares cli wallet. How familiar/comfortable are you with the command line?

Also if you use the lite wallet, make sure you have the latest one i think it ends in 420 instead of 406. If you still cant find it you can use the memo field and follow the directions xeldal posted here:
