301  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [XMR] Monero - A secure, private, untraceable cryptocurrency on: July 28, 2014, 12:47:21 PM
Hello

I am a Monero holder mostly because it has mixed transactions and many others also think that the coin of the future has this feature.

There anyway are some other coin with mixing feature.
https://cryptonote.org/
Bytecoin (BCN)
Aeon (AEON)
Boolberry (BBR)
Dashcoin (DSH)
duckNote (XDN)
Fantomcoin (FCN)
MonetaVerde (MCN)
OneEvilCoin (OEC)
Quazarcoin (QCN)

I hope Monero will be the one who survives and many others think so. I just do not yet know what is the advantage of Monero in relation to these other coins?

I have been looking for Linux GUI wallet for Monero. Great to see there is some activity to create such.

I tried these.
https://github.com/Neozaru/bitmonero-qt
https://github.com/jwinterm/cryptonoteRPCwalletGUI
https://github.com/BitKoot/CryptoNoteWallet

Unfortunately I was unable to make them work yet. Bitmonerod and simplewallet did not work either, I had problems in updating the blockchain.

When do you think there would be available a Linux-GUI-Wallet for Monero? It would be great if there was everything, like daemon, GUI and all other necessary files in one downloadable zip-file to make installation as easy as it could be.

Okay, there was a reason why I wrote on alts. Cause I have just made my first altcoin investment ever! Monero has a trait which pretty much all other alts lack: slow and geometrically decreasing issuance.

Hello Risto.
How do you store your Monero? Mac or Windows? Would you offer any Monero holding services?

I am Linux user and have been unable to install working Monero wallet, not daemon or GUI. Can anyone help on this? Are Monero-wallets easy to install on Mac or Windows? I would not trust much on exchanges or on-line-wallets but is there anyway anything at least somehow reliable ones available?

Great to see there is some activity to bring Linux GUI wallet for Monero.

I tried these.
https://github.com/Neozaru/bitmonero-qt
https://github.com/jwinterm/cryptonoteRPCwalletGUI
https://github.com/BitKoot/CryptoNoteWallet

Did not work yet.

Bitmonerod and simplewallet did not work either, so it would be great if there was everything in one downloadable zip-file. Daemons, wallets, GUIs and so on, whithout need to install bitmonerod's and simplewallet's first and try to combine them to the GUI-Wallet.

When do you think there would be available a Linux-GUI-Wallet for Monero?

Well, there could be a simple solution for too big block chain.

The block chain is there to prevent the double spendings. Well. Before the very first one block in January 2009 there is no blocks or transactions. And still no double spendings have detected.

So lets start new bitcoin system and create a new first block. From the old bitcoin system we just copy all existing bitcoin-addresses to the new bitcoin system's first block and transact exactly same amount of bitcoins to those addresses. And then we just start the new Bitcoin system running.

The old bitcoin system, blocks and transactions can be forgetten.

That very first new block contains one transaction per one created address, so it is quite big, but still just a fraction of the size of the old bitcoin system's block chain.

This could work?

There is something of block chain size in the bitcoin paper.

Quote
7. Reclaiming Disk Space

Once the latest transaction in a coin is buried under enough blocks, the spent transactions before
it can be discarded to save disk space. To facilitate this without breaking the block's hash,
transactions are hashed in a Merkle Tree [7][2][5], with only the root included in the block's hash.
Old blocks can then be compacted by stubbing off branches of the tree. The interior hashes do
not need to be stored.

A block header with no transactions would be about 80 bytes. If we suppose blocks are
generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems
typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of
1.2GB per year, storage should not be a problem even if the block headers must be kept in
memory.

bitcoin.org/bitcoin.pdf

So now when the bicoin has been running for almost five years, the size of the block chain could be as small as 5x4,2MB=21MB.

But it is not. It is almost 12500MB.

So what is true? Is it possible to reduce the size of a one block to 80 bytes?

What do you think?

There are plenty of threads on this site, so I do not want start a new one.

Newbie on this site, but not newbie with the bitcoin. I am happy owner of many coins. Also I understand the things like bitcoin-address private-key, paper wallet, online wallet, wallet applications, difficulty factor, decentralized network and such.

Still one basic thing is not clear for me.

Mining is there for creating the new bitcoins until all are created. Mining is also there for maintaining the bitcoin-network by managing the transactions and adding them to the blockchain. So I was wondering  both the creation of new coins and the maintenance of the bitcoin-network is done by the same software.

But it looks like they are two separate softwares?

Here is available original bitcoin source code. Can you give me link for a brand new one?
http://www.bitcointrading.com/forum/bitcoin-clients/original-bitcoin-source-code-archives/

And here is avalable bitcoin mining software.
https://github.com/luke-jr/bfgminer
https://github.com/ckolivas/cgminer

So the miner and bitcoin-source code are two different softwares? I know the low profit of mining, so I hardly start mining right now, I am just interested of relation between maintenance and mining.
