Hi,
I would like to introduce my blockchain explorer.
emercoin.mintr.org

If you are using an opennicproject.org DNS:
mintr.emc

Github: emercoin-blockchain-explorer

In addition to this blockchain explorer there is an online wallet (beta). USE ON YOUR OWN RISK!
This wallet also provides a Proof-of-Stake pool. Therefore you will receive regular interest for your coins!
The payout for stake-coins is bi-monthly (01 & 15). The amount of stake-coins for your account will be calculated daily.
You can withdraw your coins at all time. Your coins won't be hold back while staking.

Please leave me a comment for bug reports or feature requests.
I will try to update it in my spare time.

Great to see so many additions in the changelog!

a suggestion: it would be useful to see some statistics on the use of EmerCoin Name->Value System, particularly stats on the use of the DNS. *.coin, *.emc, *.lib, etc. Statistics on how many domains registered (maybe even list them), and also other statistics about use of EmerCoin's NVS (interesting to know how many NVS transactions are not involving DNS). I think there's a lot of interesting data that could be displayed in this area.

I'll try to implement some statistics and a NVS browser as well. But I don't know if it will be possible to identify NVS transactions in the blockchain and the current emercoind version only provides listing the whole NVS at once. Therefore it won't be possible to identify the transaction at which one value was added or changed (or maybe I'm currently not aware of the feature which will provide this).

--
Just found out that there is a "registered_at" value. That might help Wink. I've overseen that the whole time...

--
A first version of the NVS browser has been released.

Hi,

here is a short description of the new tracing feature.
It will visualize the addresses and coins which were affected in sending those coins to a desired address.

You can access this trace by clicking the new icon within the block detail page, next to each EMC input or output:


Additionally there is a link within the transaction detail page:


It will trace with a maximum depth of three transactions.
No matter how complex...


...or simple the trace will be

How to use this EmerBoard release:

The EmerBoard is designed to display messages which are stored in the value field of the NVS within the  blockchain.

How to write a message?
You can use the Emercoin client and add a new name:value pair to the NVS.
The name should look like this: channel:type:subject
If you don't use this name scheme it might not be accessible with this EmerBoard version.
The message has to be entered in the value field.

How to browse through specific messages?
Please access: http://emer.coinchains.info/emerboard
At least you have to specify a channel to access the latest messages within this channel.
Additionally, you can add a type and a subject. The subject is also capable of wildcards (*).

For example:
If you want to offer some potatoes.
Name: "ads:sell:5 potatoes"
Value: "I want to sell 5 potatoes for 5 EMC only. Please contact potatoes@eat.me"

The EmerBoard will try to identify hyperlinks or email addresses to make them clickable. Additionally, it will look for pictures behind links to create an image link.
Returns/New-lines within the value field are possilble too.

You will also earn coins when other users use this service because a part of all fees will be send into the stake-pool.

I am excited by this. In addition to Proof-of-Stake wallet, you're also providing ability to register NVS entries? That's great.

Do incoming deposits show up? and how many confirmations are required?

I sent some coins to https://emercoin.mintr.org/address/EVvSRL18rZvGBy1RmpRo47ZKhNMHRNqtrW That's my wallet address but none are showing in the wallet

I'm currently checking why your coins are not credited.
I can see the incoming transaction but no entry within the database.
I'll fix this asap.

-- Update --
Your coins are now transferred to your account. Min. confirmations are three.
I'll have to check a script which is collecting these coins. After a server reboot it didn't come up automatically. I've started it manually and it's working now.

--Update--
It's working fine now. I've created cronjob to check every minute for incoming transactions.

To use the minting chance feature, click on the leaf icon in the address detail page:


The minting chance is based on the current PoS difficulty and shows your chance to mint within 24 hours.
If you think the code might be wrong, please let me know. I've used parts of the JS code of this page: http://poscalculator.peercointalk.org/ to write my PHP sktipt. In PHP I'm calculating with 16 decimal places which might explane some slight differences to the original JS skript.

Have you thought about providing an interface in your online wallet to manage emcLNX advertisements, both from ad Buyer & Hoster points of view? I think it would be a attractive/convenient option for maintainers of lightweight websites that can't justify running an EMC full node on their servers. You could provide an interface for updating advertisement text and links, language, keywords, etc, and provide stats of how many advertisements were displayed/clicked/etc.. to make money, you could add your own small commission on top of all referrals.

Yes, that sounds very intresting.
I haven't found the time to evaluate emcLNX for me. But I'll do it later. Wink
I'll let you know if/when I have made something like this.

Thank you for your report.

There was a bug in the coin collection script. This should be fixed now.
Could you please check your balance again?

This bug has affected a few other users too. Please check your balance if you have sent coins within the last three days to your wallet address.
