Actually what is a cold storage (in bitcoins)? I didn't get it.. Cold storage doesn't have private keys or what? If it have a private key then cold storage can also be hacked by some malware, keyloggers, etc., right? An online wallet can be used as a cold storage? Or i should have any special equipments for cold storage? Cold storage is something like bit mixer/laundry? Cold storage transactions are off blockchain? ~Rude Boy Title: Re: Need to know more about cold storage Post by: dznuts85 on April 09, 2015, 02:22:57 AM Hello!

Title: Re: Need to know more about cold storage Post by: Amph on April 09, 2015, 06:18:41 AM cold storage are like hot storage, but they are disconnected from the internet , that's why they are called "cold" storage, they could be paper wallet or usb, or another desktop
you just put a backup and a new wallet there, for security purpose Title: Re: Need to know more about cold storage Post by: Muhammed Zakir on April 09, 2015, 06:24:44 AM Hello! Actually what is a cold storage (in bitcoins)? I didn't get it.. In general, cold storage means to keep the a thing in a place for preservation. For Bitcoin, cold storage means the same. Simple definition is storing Bitcoins in a thing which is not connected to internet. Cold storage doesn't have private keys or what? If it have a private key then cold storage can also be hacked by some malware, keyloggers, etc., right? Cold storage will contain private keys. Yes, cold storage can also be hacked by malwares and keyloggers. However, for this to happen you need to access directly or indirectly using a USB or other disks. This rule doesn't apply to every cold storage. For example, a paper wallet is a cold storage and obviously, it can't be hacked. An online wallet can be used as a cold storage? Like I said, online wallet will be connected to internet. So it can't be used as cold storage. NB: If you mean wallets like Blockchain.info, Coinbase, Xapo etc... by "online wallets", I highly recommend you not to store your coins in online wallets unless you know what you are doing. Or i should have any special equipments for cold storage? An offline computer or phone is enough for this. You can also use a paper wallet and use Mycelium to spend Bitcoins from it. If you have many Bitcoins to store, I highly recommend you to buy a Ledger or Trezor hardware wallet. Cold storage is something like bit mixer/laundry? No, they are mixers. Mixers help you to secure your privacy and cold storage help you to secure your Bitcoins. Cold storage transactions are off blockchain? ~Rude Boy No, it isn't. All transactions will be on-chain.

If yes, please correct it. This may confuse other users. A back up in a place never will be a cold storage. What you store in cold storage must not be in a hot/online storage. If yes, then there isn't a need for cold storage because cold storage is protect your Bitcoins from hackings and all but if you store this in a hot/online wallet, private keys are already exposed to danger.

The cold wallet question bring to my mind the Bter cone 'hack', they have said someone stolen 7'000 bitcoin from their cold storage but the unique way for hack and stole those Bitcoins was to be physically in front of that machine/device. Remember if you expose a cold wallet online also for 1 minute you can't continue to name it 'cold' Title: Re: Need to know more about cold storage Post by: Amph on April 09, 2015, 09:20:58 AM =snip= you just put a backup of your wallet there, for security purpose Maybe you didn't phrase this correctly.

But you can use a computer that is not a web surfing computer to load it and fill up your hot wallet if needed. You do try to make sure to use it as less as possible. And keep offline as much as possible. Title: Re: Need to know more about cold storage Post by: ChuckBuck on April 09, 2015, 12:42:09 PM Hello! Actually what is a cold storage (in bitcoins)?

Cold storage transactions are off blockchain? ~Rude Boy There already exists numerous answers to your questions. For you to not get confused, just keep in mind the terms offline and online. A hot wallet is a wallet that is always connected to the internet. The purpose of having a hot wallet is to move funds from one place to another quickly. Most of the time, these hot wallets contain a very little amount of bitcoins because it is more prone to hacking than the offline wallets. On the other hand, offline wallets, or "cold storage" are wallets that aren't connected to the internet and most of the time contains big amounts of bitcoins. Title: Re: Need to know more about cold storage Post by: tyz on April 10, 2015, 02:58:06 PM The best cold storage is to print your private keys on a paper (don't mention on it that it is Bitcoin-related), copy it several times and store these papers on several locations. To be safe, make a USB copy additionally. Finally, delete the private keys from your laptop, if you use it to get into the internet :)

If it is exposed online than it loss the cold property and it "is not more secure". For generate a real cold address you should choose a "secure" machine with windows (maybe better linux) and "use" bitAddress or client/wallet (downloaded from another machine, and transferred through USB or other storage supports) to generate your offline address. The final thing to do is send your bitcoin to that address and protect your laptop with several "copy" of your private key (into a sheet of paper, cd, floppy, sd,etc...); a real private key of a "cold" wallet address should never be exposed online.

You can also use a PC which is not and never will be connected to internet. But if there is already 2 PC/mobiles, I don't see the reason for using a paper wallet. However, if you are HODLing Bitcoins for a long time, paper wallet is good if you take enough precautions for preventing it from getting damaged. If you are using a paper wallet, Mycelium is recommended for spending Bitcoins from it.

Exactly. I'm surprised how many people think they have "cold storage" just because it isn't readily connected to the internet. Never let your private key touch an internet connected machine. If you spend from your cold wallet, it's no longer cold and you should move your remaining coins to a new cold address. Personally, I generate my cold addresses with dice, and then convert that base 6 key offline so I can get the public address. The private key is never saved or printed or connected to the internet, I have my private key written in my 99 dice rolls.

I will give an help, the bitcoin are stored in the blockchain so when you send a tx to a cold address (check any by block explorer) you will find that your btc is in that address. When you want to "move" the btc in that address (also if you don't see them in your offline wallet, you should only sign a raw transaction and push/broadcast it on any other device (connected to Internet). Title: Re: Need to know more about cold storage Post by: Muhammed Zakir on April 11, 2015, 06:43:07 AM See above, How to transfer BTC to an offline wallet which is never connected to internet (here don't bother about hard wallets). If yes, then this transaction is off-chain transaction right? ~Rude Boy See redsn0w's answer first. You misunderstood what is "off-chain" transaction. Off-chain transactions are transactions which isn't stored in "Blockchain". When you do an off-chain transaction, the Bitcoins aren't "really" being moved. You are only getting a confirmation receipt from the company. Off-chain transactions are generally bad and it contradicts some of Bitcoin rules: • You need to trust the company or person who handle off-chain transaction. • Off-chain transactions are reversible. • Off-chain transactions promote & focus on centralization. • Off-chain transactions don't have public proof(aka ledger). There maybe more but I think this is more than enough. If you didn't understand redsn0w's correctly, here is an answer from Stackexchange. Quote The "blockchain" is a constantly growing database of transaction information which is sent out to all nodes in the Bitcoin network. When you perform a transaction, that transaction is distributed to the network and assuming the transaction is valid, will be included in the next "block." This is where the coins themselves are stored. When you initiate a transaction, all previous transactions to or from that address are scanned and a balance is calculated. If your transaction exceeds this available balance, it will be rejected by the network and will not be included in a block. It's also important to note that the blockchain technically doesn't store "coins" it stores transaction information. The coins themselves are not discrete things which need storage - when coins are mined the miner's balance is credited via a "generate" transaction which adds to his or her available balance. When coins are sent from A to B, that transaction subtracts from A's balance and adds to B's balance. This is similar to the way that your employer may, via EFT, send "money" to your bank and you can use your debit card to spend that "money" in a store, all without anyone ever seeing a discrete physical dollar bill. Most money in the world today exists merely as transaction histories and balances - Bitcoin is no exception. Edit: Added few words.

So for your cold storage address all you need is the public key aka bitcoin address. This can be generated completely offline, the only thing you need to do is then go to your hot wallet and send coins to that cold address you just created. Now your coins are in an address where the private key has never seen the internet.
