Namecoin DNS proxy for Chrome is very good, and EMC Dev should research it.

https://chrome.google.com/webstore/detail/boghalnjcplaepdogcbcfjgbaooakkik

Github link to similar NameCoin plugin for Firefox. https://github.com/namecoin/Convergence

Never used it myself, just posting for info. Looks like it stores a local copy of the blockchain.

Hi,

I tried to compile the latest source (0.3.0) on a RaspberryPi with raspbian running.
The dependencies are installed except for miniupnpc, but I disabled UPNP in the makefile.unix

I got error messages when executing "make -f makefile.unix" and don't know what to read from them:

Try to set ENV variablese, defined in the file bldFreeBSD.sh (maybe, different pats on your system):

export BOOST_INCLUDE_PATH=/usr/local/include
export BDB_INCLUDE_PATH=/usr/local/include/db48
export BOOST_LIB_PATH=/usr/local/lib

I tried to alter that -  no success. It doesn't look like bldFreeBSD.sh is used when making with the makefile.unix.

The compiler doesn't come to an end after this warning. The last time I tried the whole RaPi got stuck and I thought I better as for help. I'll try it again!

Thank you!

[edit]
Seems to have been an issue with the RaPi when it got stuck. Tried the compiling again and it worked fine.
Thank you!

Another 2 topics that crossed my mind:
Is a testnet available? I haven't found any information in this thread nor on the homepage...
What are IP addresses of testnet nodes to put into the emercoin.conf?

And regarding security: http://emercoin.com/#specs (tab#2 "Security") states
Quote
For a successful attack on the network, the attacker must accumulate 51% of the computing power, and 51% of M1 aggregate (total coin supply). This task is much more difficult than just to accumulate 51% of the network's computational capacity.

Is the block trust value of PoW blocks significant?
I don't remember in which file of the source code to look after the calculation, but as Emercoin seems to be a fork of Peercoin, I'd wonder if the PoW blocks have a significant block trust value...
To attack PoS 51% of all actively minting should be enough, right?

There is a local testnet which you can create by writing testnet=1 to emercoin.conf. But you will need at least two testnet wallets connected to each other to start mining blocks. Here is an example of two such configs:

1st config:

# Run on the test network instead of the real bitcoin network.
testnet=1

# server=1 tells Bitcoin to accept JSON-RPC commands.
server=1
daemon=1

# You must set rpcuser and rpcpassword to secure the JSON-RPC api
rpcuser=testnet1
rpcpassword=testnet1

rpcallowip=127.0.0.1

# Listen for RPC connections on this TCP port:
port=9531
rpcport=9532

# add testnet wallet nr 2
addnode=127.0.0.1:9731

2nd config:

# Run on the test network instead of the real bitcoin network.
testnet=1

# server=1 tells Bitcoin to accept JSON-RPC commands.
server=1
daemon=1

# You must set rpcuser and rpcpassword to secure the JSON-RPC api
rpcuser=testnet2
rpcpassword=testnet2

rpcallowip=127.0.0.1

# Listen for RPC connections on this TCP port:
port=9431
rpcport=9432

# add testnet wallet nr 1
addnode=127.0.0.1:9531

Hi Fixx or Maxihatop,

Do you know any reason why EMC might not work in windows XP?

Someone was asking at the Cryprocointalk forum: ( https://cryptocointalk.com/topic/2144-emercoin-emc-information/page-2 )

I also tried to run in XP and it appears to crash immediately.

Thanks!

You are doing great job guys with emc in technical area.
It just needs more promotion and more exchanges.
About the F@H project, i haven't seen a payment for several days now. It is just me or you made any changes?

Thank you!
Unfortunately, I'm the only one who recharges Emerfor lately Sad
But understand? EMC coin without premine, thus I have had an equal chance with other participants of the mine. And that means that my reserves, though significant, but limited.

Perhaps in the future we shift funding to F@H enthusiasts?

I believe that pre-registration offer is over, since we can now register names directly in the EmerCoin software, as described at http://emercoin.com/2014-11-05-EmerCoin_0.3.0_Release_Notes

Costs to register a name in the system are currently about 260 EMC per name. That's due to the "early name penalty", but that's disappearing quickly.

Anyway, have sent you a few EMC to get your started. Wink

I registered news.coin domain and set the IP 192.227.235.xx, and at the day before yesterday, I use name_update to reset the IP to 138.128.120.111, the problem was happened!

When I visit news.coin site and the IP is still 192.227.235.xx, I tried some different computers and got the same wrong result, but i visit news.coin.emercoin.net and it is fine.  Are there caches for the old IP?

Please fix this problem DEV.

The problem in your local caches, where saved old IP.

With EMCDNS, your address resolved correctly:

$ dig news.coin @localhost -p5335

; <<>> DiG 9.8.3-P4 <<>> news.coin @localhost -p5335
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 51597
;; flags: qr rd; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; WARNING: recursion requested but not available

;; QUESTION SECTION:
;news.coin.                     IN      A

;; ANSWER SECTION:
news.coin.              86400   IN      A       138.128.120.111

Also, same work for emergate:

$ host news.coin.emergate.net
news.coin.emergate.net has address 138.128.120.111

Thus, you see, DNS system works OK.

I think, you did not specified TTL value for your record.
And, as written in the document: http://emercoin.com/DNS_and_Name-Value_Storage
The default value for TTL is 24 hours.


So, I assume, everything works, but old record exist in some your cache.
When it will be expired, a new value will be loaded.

> Please fix this problem DEV.

We cannot refresh caches on _your_ computers, sorry.
Just wait, please.

Pretty sure this was the stated intention of the devs from very early on, to avoid a speculative bubble / pump-n-dump.

I understand the devs don't actively look for exchanges, but of course, exchanges are welcome to add EMC.
