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?
thanks

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?

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!

Thanks for the info!

We have almost completed the release of the patch.

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

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

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

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

its not a "error message", only a warning. just ignore it.

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!

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:

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.

Yes, it's really cool!
Do you have anyone in mind? A programmer who is able to write plugins for the browser?

Great job!

When could EMC Dev release a new DNS server that public browser can reach .coin domain without any plug.

The *.coin domains are already reachable through a gateway such as emergate.net. But to have direct public access to the .coin domain will require your DNS provider support it.

It will take time, but I believe the EMC team are already working on seeing the domains supported by some DNS providers.

Until then, you would need to rely on a gateway such as emergate.net, or set up your own local DNS server as described in the 0.3 release notes.

EMC

Use EmerCoin NVS to deploy and manage Public Key Infrastructure!

Users can manage their own login credentials (public keys) by submitting and modifying records in the EMC blockchain (using the standard EmerCoin GUI or daemon). Similarly, admins can manage user groups for their services that may contain references to other groups as well as individual users - allowing for the creation of recursive authentication trees. Records are considered secure and unalterable due to the nature of blockchain technology.

Comparing to the most popular alternative - storing public keys in the LDAP server, this system has the following advantages:

This is first world-wide PKI system. Not just enterprise-level, but real world wide.
Not needed setup of dedicated LDAP-server(s) as domain controller - info retrieved from local wallet program.
Impossible situation, when user cannot login to server, because of LDAP server is unavailable or down.
Impossible situation, when attacker insert into LAN fake LDAP server, and get access to all computers at once.
Sensitive information retrieved from a wallet locally, and cannot be blocked/intercepted/alerted in the network.
Easy to configure, no troubles. Just plug and play.
WorldWidePKI - for WorldWideWEB. System can be used for authentication to another services - e.g. for WWW-servers.

Congratulations to the EMC team on this important update. The domain names are already extremely useful!

Is update required? Particularly I am wondering if exchanges must be notified... or is it safe to continue using previous version?

Messy, sorry, I didn't understand from the first time.
Sure, to see all new features you have to download the new version.

No you are right the first time

I'm just making sure that coins are safe and on correct chain when using old wallet (otherwise, exchanges would need to be notified).
