[EMC] EMERCOIN — Blockchain Service Platform. PoS&PoW | BTC merge-mined

[Valermos]

Hi,

just want to announce my new online wallet feature. With this change I've also changed the URL (and the server):
emercoin.mintr.org
(previosly: emercoin-blockchain.info or emer.conchains.info. To save costs I won't renew them in the future. At the moment they point to the wrong server.)

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

The online wallet comes with a proof-of-stake pool. Additionally, you will earn a part of the service fees too.
It also supports EMCSSL after registration. EMCSSL registration is not possible and also not really necesary, since all you need is a username and a password.

The stake will be calculated daily. Payouts are bi-montly (01 and 15).

Please use with caution. It's not tested on the long run (early beta). Some planned features are still missing. I'll add them in the future.

[Fixx]

Excellent, great idea!

Now we have the opportunity to very easily manage record name NVS.

But there are fears login registration (for prevent registration spam). It is better to make it safer (CAPTCHA, google) A perfect - use system EMCSSL!

[Valermos]

Thanks for your feedback.
I'll have a look on how to address this spam problem.

[BitcoinFX]

wow - EmerCoin project has some really great additions since I last checked in - good stuff.

- I operate 3 Tor Exit Servers (Russian hosted) which are using DNS resolvers from OpenNIC Project.

Thus, these .exits will resolve .emc domains over Tor. You can select using only said servers by editing your torrc (Tor Browser config.) adding the following;

Code:

ExitNodes startor0ru,startor1ru,startor2ru

and maybe:

Code:

StrictNodes 1

See: https://www.torproject.org/docs/tor-manual.html

Just remember to remove the above when you finish visiting or testing .emc domain's over Tor - to revert back to normal default 'random' operation.

Cheers!

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

Here's some thoughts for you:

1. It could be a good idea to provide a web form specifically for domain registration, with a similar feel to conventional domain registrars.  e.g. a form with fields for "name servers" "mail exchange", etc (for editing the complete "zone file" like in this image: https://www.linode.com/docs/assets/1121-dns9.png) Then you could parse the form and submit the appropriate data to the NVS, without requiring users to know the NVS innards. This way, you could present/market the service as a domain registrar in a similar way to how https://getdotbit.com/ or https://www.netki.com/ do for namecoin.

I'm sure you've already thought about this

2. A small thing: Firefox didn't offer to save my login credentials for me, like it does almost all other sites. Some people do use that for convenience.

3. It's great that EMCSSL can be used after registration, although I couldn't see EMCSSL mentioned anywhere on the site (perhaps it could say something under the login form like "...or login to existing account with EMCSSL" with a link to http://emercoin.com/EMCSSL_GUIDE , or just include some clarifying information about how EMCSSL can be used on the site)

4. I've updated the link to your service at emercoin.com, under EXPLORER#1 and also added a new link under "Mining pools". I've been helping the team with the main emercoin website so you're welcome to PM me with better ideas for how you'd like your service mentioned.

Cheers.

Exactly. 
I'll put this on the list and keep your other points in mind. As soon as I have some spare time again I'll work on this and on the captcha Fixx has mentioned.

Thank you for your feedback!

Released EmerCoin wallet, v 0.3.4.
Download here: http://sourceforge.net/projects/emercoin/files/

This version is 100% compatible with old one.

Added minor improvements:

1. Added and activated config option -walletnotify.
This is useful for integrate EMC wallet into complex system, like automatic payment collectors, exchnages, etc.
Details here: https://en.bitcoin.it/wiki/Running_Bitcoin

2. Improved PoS minting. Added delay ~3 minutes after successfully closed PoS block.
This preserve series of block closing from correlated UTXOs. PoS reward will be unchanged.

3. Added alternative seed search mechanism, based on emcDNS system.
In hypothetical case, if domain emercoin.com will be blocked, client can just switch DNS to OpenNIC
(https://www.opennicproject.org/),  and fetch seed info from distributed EMC DNS system.

I've updated my node to the current git master.

Once i see this in my logfile, 1 thread of emercoid (niced at 19) uses 100% cpu until i kill -9 it. emercoind is stuck.

Code:

uint256HashMap:Set(517/1024) data=56 sz=57344

also this only happens when i unlock my wallet for minting!

[maxihatop]

> Once i see this in my logfile, 1 thread of emercoid (niced at 19) uses 100% cpu until i kill -9 it. emercoind is stuck.

Is this always happening? Maybe, after restart, there is not deadloop?
We cannot reproduce this bug on our wallets - on Linux, BSD and Windows everything seems OK.

If you can repeat the bug, please note us, where it happening. To do this, run (without daemon mode):

$gdb emercoind
(gdb) r
[wait till deadloop]
CTRL/C
(gdb) where

This command shows us runtime stack.
Another option - give us ssh-access to your machine, and we try debug ourself.

> uint256HashMap:Set(517/1024) data=56 sz=57344

This is OK. This is just our new container created, used for caching minting.
This code had been added into 0.3.3, and has not been changed in 0.3.4

For assistance, contact us: team@emercoin.com


So, I assume, problem isn't relevant to this container. However, need debug more deep.

[maxihatop]

Site clone!!!

We noticed, there is appeared a new site emercoin.net.
This is copy of our main page, without working links. However, there is exist the new button "LOGON" in upper-right corner.

We, EmerCoin group, note: That site is irrelevant to our project, and we do not control or responsible for that site content.
Also, owners of that site did not contacted us.

Perhaps, this is phishing or another kind of fraud scheme. Please, be alerted.

its running in gdb now (had to set args daemon=0 so it dosnt go into background) with debugging symbols.
i also see lots of those

Code:

i've used v2.2 before i tried 3.3

[maxihatop]

> i've used v2.2 before i tried 3.3

2.2 is too old version. Since 3.0 there is many changes. Maybe, some old file has conflict with new engine.
Try to reload blockchain.

For do this:
 - backup your wallet.dat
 - in directory .emercoin, delete everything, but emercoin.conf or wallet.dat
 - run emercoind, and refresh blockchain.

If it will not help, I suggest:
  - create fresh emercoin wallet.
  - move all funds from old wallet to new one.
  - forget about 2.2

its a problem with minting...

Code:

uint256HashMap:Set(327677/524288) data=64 sz=33554432
ThreadRPCServer method=listtransactions

Once the size/set is getting too big, it deadlocks. no more RPC commands are possible.

The bt isnt helpfull either

the other threads dont show anything obvious (syscalls)

i will resync from scratch in this case.

[maxihatop]

Maybe, need just wait for minutes, until huge list of UTXOs will be load into cache?
For 1st glance, uint256HashMap must keep up to 1,000,000,000 records.
Your list much less. So, this is not it. What is it - I don't know.
as result, I see 2 possible ways:
1. You move funds into another wallet, and decrease TX qty by this way.
2. You will provide me access to your machine, and I will try to debug on your wallet.

Thanks for the warning. This is a mystery, why anyone would clone the emc website like this. Hopefully they plan to use it for some good purpose and didn't announce it yet.

In secret laboratories gradually completed miner (mining rig) with EmerCoin wallet and blockchain on board.

By the way - the world's first use of blokchain in embedded system.



This solution gives 4 new features:

 

1. Control terminal access Miner (array miners) through emcSSH.

2. Management WEB-access through a secure emcSSL to the same array of miners.

3. Management of the ACL for the [2] through the subsystem [1].

4. The ability to solo to the local Mining purse, located directly inside the miners. That is a miner becomes fully self-sufficient.

 

In the photo you can see the control unit miner (raspberry pi), which displays the solo mined balance :

 



 

Miner series will be produced by HashCoins (https://www.hashcoins.com/).

There will also be released firmware, which allow owners of miners previously purchased upgrade to make this company and get new features.

emcLNX

EmerCoin Link Exchanger (emcLNX) is a new innovation from the EmerCoin developers:

emcLNX is a peer-to-peer text-advertisement network based on a pay-per-click model, running on the EMC blockchain.

If you have a website or a product to advertise, you should give this a look.

Full details are at http://emercoin.com/EMCLNX

I merely helped to brush up the text for better English, but if anyone has any good questions please ask them here. I will be glad to help find answers or add to the FAQ on the emcLNX page.

It will be very interesting to see how use of emcLNX develops!
