I have this question, say I have my coins in my local wallet and 1 of 2 things can happen, say I somehow delete the wallet.dat file or some kind of malware deletes the file. I have the password private key to the wallet, would I need the wallet.dat file to recover the bitcoins or could I just recover with the private key to the address? Would I need both?
Do they write wrappers around bitcoind or is there a better solution out there? Some exchanges handle dozens of digital currencies, does this mean they are running bitcoind, litecoind, dogecoind, etc concurrently?
I’ve been poking around https://en.bitcoin.it/wiki/Target and I’ve found the current target, but I can’t seem to find how it’s generated. It’s supposedly generated when the difficulty is adjusted, as stated here: https://en.bitcoin.it/wiki/Block_hashing_algorithm, but what exactly is the algorithm for generating the target? If someone could show me some psuedocode that would be great.
"addr": "typicalbitcoinaddress",
"compressed": true,
"encrypted_privkey": "this is my private key that is 96 characters long",
"label": "Wallet",
"pubkey": "Public key of the address",
"salt": "random small set of digits not sure what this is"
I dont know how to convert my private key that is under “encrypted_privkey” (96 characters long) (Not sure what it is encrypted to) to a Wallet Import Format like to import it into blockchain.info….Any help on the process to convert this to a WIF private key would be greatly appreciated, I am unable to provide the private key of course…
I’m having a hard time understanding how nLockTime works. The Bitcoin wiki has an explanation that is confusing to me:
nLockTime is a parameter that can be attached to a transaction, that mandates a minimal time (specified in either unix time or block height), that before this time, the transaction cannot be accepted into a block.
Can someone explain it in plain English, with an example?
I’ve recently reformatted my Mac, and reinstalled Hive. I have a back up to Dropbox option enabled in Hive, and my old bitcoin wallet file is there. But I cannot find any way to recover my old bitcoin wallet to my new installation. Being able to back up but not recover doesn’t make much sense to me right now, can anyone help me with this process?
We are developing UI for coin trading. We have a plan to use all the coins present in coinmarketcap. I am greatly confused how to generate coin address for all coins. I knew that from cryptsy.com, it is possible to generate address for all coins from bitcoin but I don’t know how to implement it. Is there any easiest way to generate coin address for all coins or can anybody tell how cryptsy do this for all coins? We are doing this in Ruby. Can you please suggest some more ideas to implement this. Any help is appreciated.
Blockchain has great documentation for PHP, but nothing really for node!
Does anyone here have any projects,where they used the blockchain.info Receive Payments API, in their node apps, to receive money / check for confirmations?
I learn a lot better by viewing / recreating example code so any you have would help me out tons!
I want to create a brainwallet using a custom diceware since I don’t like the original one. Instead of 7776 words it has 46656 because I use 6 dice for each word instead of 5.
So this is what I got so far, please tell me if I made a mistake:
2 ^ (log2(46656) * 5) / (1 * 10^15) / (60 * 60 * 24 * 365) = 7 years
I have to admit I don’t fully understand the Bitcoin protocol. But from what I do understand, transactions are traceable — it is the main reason decentralization works: the world can watch and confirm that a transaction is legit.
Why then can’t we observe when a thief tries to cash out or otherwise exchange a Bitcoin that we know to have been stolen?
1 out of every 14 Bitcoins is now stolen property, and there are
plenty of laws governing stolen property.
What am I missing here? With so many Bitcoins identified as “stolen,” why can’t they be traced, recovered and returned to their rightful owner?
