It seems a pretty interesting project, ICO is pretty good, but I'm not sure to join,
I'll keep seeing the next developments and within a few days left to join the signature campaign, I'll keep seeing until I decide to join or not, good luck

Thanks a lot for the interest. Currently tearing my hairs out while fighting with Visual Studio to compile the Windows wallet.  

Also I found out that you NEVER should use walletd to open a wallet created with simplewallet, as walletd will save the wallet in a different format that can't be opened with simplewallet anymore. Luckily it's possible to export the keys and import them back into simplewallet.

Inserting data into the tx_extra field requires the use of walletd RPC commands at the moment, which is new to me, I have a lot to learn. See https://wiki.bytecoin.org/wiki/Send_transaction_-_Bytecoin_RPC_Wallet_API . If an experienced dev wants to help, shoot me a PM.

Also to clarify: There will be no ICO.

The good news: The test network is running smoothly and I mined a ton of worthless coins.
The bad news: I am so far unable to add extra data to a transaction.

According to https://wiki.bytecoin.org/wiki/Send_transaction_-_Bytecoin_RPC_Wallet_API, this should work:

Code:

curl -X POST -i -H "Accept: application/json" -d '
{  
  "params":
	{  
	"anonymity":0,
	"fee":1000000,
	"unlockTime":0,
	"paymentId":"",
	"addresses":
	[  
	"iz4Z1u39PLbg3djCXo9CBGdXRLrBtf7ceTfmZAsvhaANUBQixShfRXV8eyaoAQJmqhZYuZyar6ptbXUBNufDi6c51yxiqr8wJ"
	],
	"transfers":
		[  
        	{  
           	"amount":10,
           	"address":"iz5NJ4B5Rc6AmtoiVFoJy2jWGDvKPMGuoGCmNxL2t9sXZ2LUXUJPZLrX3pLau4P9tjY4M2VyoYGPWjn6mETrNsqJ2T21YtMtx"
        	}
		],
	"changeAddress":""
	},
	"extra":"HELLOWORLD",
	"jsonrpc":"2.0",
	"id":"test",
	"method":"sendTransaction"}
' http://127.0.0.1:8070/json_rpc

This is the output I get from walletd:

Code:

HTTP/1.1 200 OK
Content-Length: 773
Server: CryptoNote-based HTTP server

{"id":"test","jsonrpc":"2.0","result":{"transaction":{"amount":-1000010,"blockIndex":4294967295,"extra":"016d7bb13f30dffd6e62361abbf0eb64b1d946455bd5d2d4bf37f63c11fbece5f0","fee":1000000,"isBase":false,"paymentId":"","state":0,"timestamp":0,"transactionHash":"23dabee38c0354bc8dbd4c800e19d9df1295c5a2fc237969cf8fb3e67c45793a","transfers":[{"address":"iz5NJ4B5Rc6AmtoiVFoJy2jWGDvKPMGuoGCmNxL2t9sXZ2LUXUJPZLrX3pLau4P9tjY4M2VyoYGPWjn6mETrNsqJ2T21YtMtx","amount":10,"type":0},{"address":"iz4Z1u39PLbg3djCXo9CBGdXRLrBtf7ceTfmZAsvhaANUBQixShfRXV8eyaoAQJmqhZYuZyar6ptbXUBNufDi6c51yxiqr8wJ","amount":8999052258,"type":2},{"address":"iz4Z1u39PLbg3djCXo9CBGdXRLrBtf7ceTfmZAsvhaANUBQixShfRXV8eyaoAQJmqhZYuZyar6ptbXUBNufDi6c51yxiqr8wJ","amount":-9000052268,"type":0}],"unlockTime":0}}}

As you can see, the extra field contains no "HELLOWORLD"...
When I put the extra field above the transaction, like this:

Code:

curl -X POST -i -H "Accept: application/json" -d '
{  
  "params":
	{  
	"extra":"HELLOWORLD",
	"anonymity":0,
	"fee":1000000,
	"unlockTime":0,
	"paymentId":"",
	"addresses":
	[  
	"iz4Z1u39PLbg3djCXo9CBGdXRLrBtf7ceTfmZAsvhaANUBQixShfRXV8eyaoAQJmqhZYuZyar6ptbXUBNufDi6c51yxiqr8wJ"
	],
	"transfers":
		[  
        	{  
           	"amount":10,
           	"address":"iz5NJ4B5Rc6AmtoiVFoJy2jWGDvKPMGuoGCmNxL2t9sXZ2LUXUJPZLrX3pLau4P9tjY4M2VyoYGPWjn6mETrNsqJ2T21YtMtx"
        	}
		],
	"changeAddress":""
	},
	"jsonrpc":"2.0",
	"id":"test",
	"method":"sendTransaction"}
' http://127.0.0.1:8070/json_rpc

I get:

Code:

{"error":{"code":-32600,"message":"Invalid Request"},"id":"test","jsonrpc":"2.0"}

If somebody could tell me what tag to use, I would be forever grateful. I tried a lot, like extra_padding, tx_extra_tag_padding, basically all variations  of the tags seen in: https://github.com/euleausberlin/infocoin/blob/master/src/CryptoNoteCore/TransactionExtra.h I could think of.

Unfortunately, while there is some information on why and how tx-extra is supposed to be used, there is very little information on how to actually do it. A little push in the right direction from someone who actually knows Cryptonote would be much appreciated.

TODO: Insert data into transactions
Fix evil Cryptonote bug from a few months ago (already have the commit with the necessary changes thanks to moneromoo, but no need to do that until data can be inserted)
Windows wallet

Keep in mind how dangerous a currency like this can be.

Here is why you should not do it as of now :

You have no tools to protect this decentralized blockchain.

Great project all in all, but the name.. not really,
it's already been taken: https://bitcointalk.org/index.php?topic=1967550.0
(Note that this Info coin is already listed on some exchange)
So, I would suggest another name. Maybe Datacoin? 

[bugreporterr]

https://bitcointalk.org/index.php?topic=325735.0

Datacoin already taken and still active

[GameKyuubi]

Datacoin already exists and is still alive in the shadows.  Maybe you should work with the Datacoin community?  There are still quite a few dedicated supporters remaining.
