Logo Proposal for CryptoKernel

Hello! @mit-dci
I'm a graphic designer and I like to support open source projects. I would like to design a logo for your project if you interested, I will be happy to work with you! :)

Failed to load lz4

When compiling on a fresh Ubuntu 16.04.2 LTS Server install, I get this warning:

/usr/bin/ld: warning: libcrypto.so.1.0.0, needed by //usr/lib/x86_64-linux-gnu/libcurl.so.4, may conflict with libcrypto.so.1.1

and after running ./ckd when syncing I get this presumably at block 5774:

Tue Jul 11 14:39:53 2017 INFO Network(): Downloading blocks 5773 to 5973
Tue Jul 11 14:39:54 2017 INFO Network(): Attempting to connect to 18.238.7.30
terminate called after throwing an instance of 'std::runtime_error'
  what():  Failed to load lz4
Aborted (core dumped)

lz4.so was successfully copied to /usr/lib and I ran ldconfig (checked to make sure it was configured to look in /usr/lib) for good measure.

Not sure what is depending on lz4, maybe lua? Any hints?

Thanks.

This progam is very hard to navigate through

Most of the times there are errors or problem to connect to IP. so i chose the password from the very beginning but the daemon didn't start itself, thats why i input ckd -daemon and it says daemon started. does that mean i am already mining? also i am not sure if it linked the password to the account correctly.
I read an article on coin desk regarding ck320 and i am very interested in this concept since it can be a real currency which can be used for everyday life.

Thank you in advance,
Regards,
Givi

Daemon crashes if you use an account command on `./ckd` and the daemon doesn't have a wallet set up

Try doing ./ckd listaccounts if the daemon has walletdb set to null.

client_key_25519 / server_key_25519

How are local keys supposed to be generated? Getting this on the console:

keys/client_key_25519.pub: No such file or directory
keys/client_key_25519: No such file or directory
keys/server_key_25519: No such file or directory

CMake support

Would be nice to have CMake support for this project, I'm already inspecting ways to integrate this, can really be nice with JetBrains tools (CLion)...

Genesis creation

Hello again I see you have made good progress on this project. 😄
Just a quick question I should change bool newGenesisBlock to true and run ./ckd to generate a new genesis correct or am I missing something? It doesn't seem to work

Running multiple instances of ckd

At the moment it looks like I'm able to run only one instance of ckd on my network in connected mode.

When I run the second instance (not on the same machine as the first one of course) this second instance can't connect to peers.

Is this intentional (maybe as they are both sharing the same external IP)? Even when one of them is not mining (has miner=false in config)?

Mined blocks not accepted on the production network

The production network doesn't seem to be accepting newly mined blocks for the past few weeks. Additionally, few production peers from peers.txt seem to be accepting connections. (CryptoKernel version 0.1.0-alpha-rc4)

In particular, the public node 18.250.7.224 syncs to block 141,682 but won't accept newly mined blocks beyond that.

I can confirm that a private network with two 0.1.0-alpha-rc4 peers works as expected.

Have an option/envvar to specify install directory during installdeps.sh

Just blindly running ./configure && make install on Debian has a chance to break things, especially if there's packages for the program/library being installed. Like as is the case for libmicrohttpd.

"blockdb" parameter not honored

For some reason, when i specify a full path in the "blockdb" parameter of the config.json, it is still writing to the blockdb subdirectory of the working directory, in stead of the actual path configured. The weird thing is when i added a log statement to the Blockchain constructor, it prints out the correct path for dbDir

There is also a database in that folder, but it's empty whilst the folder under the working directory keeps growing.

Strange balance

Started second ckd instance on another computer. Sent more than 1k of balance to it's address (from another ckd account, height >70k), then first time started this new ckd instance with mining, and checking the status with getinfo I've got a strange balance output at height 6:

(height 2 still 0)

ckd getinfo
{
   "balance" : "0.00000000",
   "ck_version" : "0.0.1-alpha",
   "connections" : 1,
   "height" : 2,
   "mempool" : {
      "count" : 0,
      "size" : "0.000 MB"
   },
   "rpc_version" : "2.0.0-dev"
}

(and here is the strange balance)

ckd getinfo
{
   "balance" : "99.99973893",
   "ck_version" : "0.0.1-alpha",
   "connections" : 1,
   "height" : 6,
   "mempool" : {
      "count" : 0,
      "size" : "0.000 MB"
   },
   "rpc_version" : "2.0.0-dev"
}

Seconds after and also all consequent getinfo calls return (correct) balance 0:

(notice same height here)

ckd getinfo
{
   "balance" : "0.00000000",
   "ck_version" : "0.0.1-alpha",
   "connections" : 1,
   "height" : 6,
   "mempool" : {
      "count" : 0,
      "size" : "0.000 MB"
   },
   "rpc_version" : "2.0.0-dev"
}

(and soon after)

ckd getinfo
{
   "balance" : "0.00000000",
   "ck_version" : "0.0.1-alpha",
   "connections" : 1,
   "height" : 11,
   "mempool" : {
      "count" : 0,
      "size" : "0.000 MB"
   },
   "rpc_version" : "2.0.0-dev"
}

Any explanation of the strange balance 99.99973893 there?

Running make doc gave me a "doxygen: Command not found" error.

Can you add Doxygen to the dependencies?
