Bitcoin / Development & Technical Discussion / raw tx and change address

on: November 03, 2015, 09:50:15 AM

Hello

Want to prepare raw TX with change address.
according to the manual https://bitcoin.org/en/developer-examples#simple-raw-transaction

input had 50.0000 bitcoins and our output ($NEW_ADDRESS) is being paid 49.9999 bitcoins, so the transaction will include a fee of 0.0001 bitcoins. If we had paid $NEW_ADDRESS only 10 bitcoins with no other changes to this transaction, the transaction fee would be a whopping 40 bitcoins

I should add change address if I want to save change.

prepared Raw tx like this

Code:

./bitcoin-cli createrawtransaction 
'[{"txid":"fba4b0a1e11b68c587aae3578844d68131c807913767a1efc9a699d38ecd9f06",

Could you please share example how to prepare raw tx with address for the change and fee ?

Thanks.

Bitcoin / Development & Technical Discussion / Re: incomming transaction understanding

on: October 10, 2015, 12:50:36 PM

Thanks a lot for the explanation. It is rely interesting and cool!

Let me clarify my vision.

For example I have an address

Code:

https://blockexplorer.com/address/3GWQ24JVWjVCT4uDKnvNJEbYJSwySQM4d7

The address has 4 input tx

Code:

ba3141908a631be74dea503c6f0cdbb364e0a28df9d53f0a027b4cdeef673e9d
4c2da413bbeef2f1dd56a3d7e67af11d63eddd97906dd70afdbbcebdf9a589e7
3266dcc46b422d58b273ffd2acaf9dc2e72e26e3ec7fb82f25611341c7aea5d2
6ab8ac462b08b7883d82b69b2e8ae2e3008522ca50302f5c403dbfd16d9dc97b

So as you can see the address has positive balance.

Now, want to spend coins from the address 3GWQ24JVWjVCT4uDKnvNJEbYJSwySQM4d7

Used next command got tx info by address

https://blockexplorer.com/api/txs/?address=3GWQ24JVWjVCT4uDKnvNJEbYJSwySQM4d7

Also I can give all unspent outputs by address like this

https://blockexplorer.com/api/addrs/3GWQ24JVWjVCT4uDKnvNJEbYJSwySQM4d7/utxo?noCache=1

Code:

	"scriptPubKey": "a914a287c1558aec11c6499dea08962cee0144be3eb587",
	"amount": 0.00001,

	"confirmationsFromCache": false
}]

So in my vision if I want to spend all coins from the address 3GWQ24JVWjVCT4uDKnvNJEbYJSwySQM4d7

I should prepare rawTx with ALL Unspent Outputs is it correct ? Any cases how can I simplify it?

createrawtransaction

Code:

Hello! Do I have any chance to get hte same private key on the separated service like http://bip32.org/ or some open source HD wallet by same Mnemonic seed or pathShare ? For example: Code: DeterministicSeed seed = new DeterministicSeed("crazy horse battery staple", null, "crazy horse battery staple", new Date().getTime()); DeterministicKeyChain keyChain = DeterministicKeyChain.builder().seed(seed).build(); // Get 0H/0/5 key System.out.println(keyChain.getKeyByPath(ImmutableList.of(ChildNumber.ZERO_HARDENED, ChildNumber.ZERO, new ChildNumber(5)), true).getPrivateKeyAsWiF(MainNetParams.get())); Have got - KybWiYVNf6TsjHKqfJFeX7QaNLBppLqJiuRL84MuzXKQ2jcJuHe9 Next go to the http://bip32.org/ set paths share "crazy horse battery staple" select Derivation Path - simple and set 5 Got different private key. How can I get same private key by mnemonic code or pathshare on the separated service like http://bip32.org/ or some another one. For example some open source HD wallet. Thank you!

on: September 28, 2015, 06:08:08 PM

Hello! Want to implement BIP32 tree generation from root seed 1) Set root seed 2) Transform root seed with step N + 1 3) Generate pair of keys "private / public" based on seed "tail seed into BIP32 tree" Could you please recommend some java open sources project for this aim ? Could you please recommend online HD wallet "want to check my own implementation"?. Which does BIP32 algorithm use for generate new seed in the tree ? for example: step 1 - root seed step 2 - root seed step 2 - ? step n - root seed step n - ? BR!

hello! Can I send remain coins after delay to the default address for example 1. create raw TX and get address = "p2shaddresstest" 2. prepare TX which send all coins from "p2shaddresstest" to the "defaultaddress" 3. set timeout, for example 24h 4. send TX to the bitcoin network The main aim, prepare some transaction which will send all remained coins from one address to the another after time out.

Bitcoin / Development & Technical Discussion / Re: NLockTime with RawTx

on: September 01, 2015, 12:10:34 PM

Quote from: knightdk on September 01, 2015, 11:25:01 AM First of all, that only made you a multisig address, not a transaction. To create a transaction you need to use createrawtransaction and modify the hex to add the locktime. Then you need to sign it with signrawtransaction. Thanks for you answer. Yes I can create rawTx by the next command Quote ./bitcoin-cli createrawtransaction '[{"txid":"fba4b0a1e11b68c587aae3578844d68131c807913767a1efc9a699d38ecd9f06","vout":1,"scriptPubKey":"a914e8fa0f97c663ba132bd81e6d657c46825d390e6c87", "redeemscript":"524104d9546728bb1d1bf309ef3c2c7278d8d306052ecf7dc81443f16e75ae607099dfcfc573a3e 71553bd8321d91c209bab03aa999befa6e77734c0f4dd34ef78ebfd41041050ff637a97fa462dff a19d0bc013869f6231895019bd9f263a0a55a067665cfca4473aab1dc38e8aecf359e23ce6bb35f f900bc84fdd890a3b982ea50dd92f4104e086dce7893384cbfa89fbbf7d33de3f1ee01279a1e981 0d952f1c440e91fc7ee7cb9cf070dfbdee397e123c363d140221e81610b7bd695905fbf198edfd7 1a153ae"}]' '{"motbFuaf7Q7xWqBbo7zFu83sdNBspvYkFY":0.0001}' Do you have any example how to put NLockTime to the createrawtransaction ?
