Can I subscribe some address with bitc?
I mean if get incoming transaction for the my address bitd will send notification
or need to ping bitd each 5 seconds for example ?
Can I check bitd like online service ? I mean online API for testing

Thank you for recommendation!

Do you mean https://opensource.conformal.com/wiki/btcd ?

getTxOut by address
by
scalaz
on 12/03/2016, 13:43:42 UTC
Hello!
I'm trying to get transaction tx out by address with bitcoind. Current address does not contains in the bitcoin wallet.

Current solution

1. getblockhash
2. getblock
3. gettxout "a070c999b594d7b0922adebf00c74c69db5b2c1b6da08a83dad99c11f57c03d1" 0

Quote
{
"bestblock" : "000000000000000000ca1b3c58c26c016a1cf6331675bd4b7e303a2522a6f4ce",
"confirmations" : 231,
"value" : 0.17800000,
"scriptPubKey" : {
"asm" : "OP_DUP OP_HASH160 0596a9bc158e13ba4a75c800d317b748bfe3577a OP_EQUALVERIFY OP_CHECKSIG",
"hex" : "76a9140596a9bc158e13ba4a75c800d317b748bfe3577a88ac",
"reqSigs" : 1,
"type" : "pubkeyhash",
"addresses" : [
"1WYsDAYJBiLxLQKeSR8eLfpTumUYmuxgW"
]
},
"version" : 1,
"coinbase" : false
}

4. compare address from JSON with my address.

As you can see this is like brute force. O(n) complexity...

Do you know how to subscribe address for checking incoming tx_outs by address "address does not exist in the bitcoind wallet" 

Any Java libraries for this aims ?
Any free API ?
Any recommendations ?

Thanks!

bitcoind and new incomming block analyzing
by

on 11/03/2016, 01:05:15 UTC
Hello!

I want to analyze new incoming blocks about next data

Code:
[
{"address":"3NTyKSmiZqW8fNPnCoZgd1HwS2DqVXHKG6",
"txid":"90e3439211677936804a9190e5074db0ce3eb7468edac4f455e3a16b965804d9",

"amount":0.0005,
"confirmations":17269,
"confirmationsFromCache":false}
]

As you can see address monitoring.

I found next command

== Network ==
addnode "node" "add|remove|onetry"
getaddednodeinfo dns ( "node" )
getconnectioncount
getnettotals
getnetworkinfo
getpeerinfo
ping

So can get block by hash

How can I get all another data ?

I mean

next fields

Sorry, no so clear.

Do you mean run client like this ?

 sudo bin/bitcoind -datadir=.bitcoin -port=88888 -rpcport=99999 -rpcallowip=127.0.0.1 -rpcuser=bitcoinrpc -rpcpassword=password -blocknotify

Any examples ?

Hello!

Want to scan incoming blocks with native bitcoind client.

Could you please clarify

1. Can I connect to the bitcoind "pipe line with incoming blocks"
2. How can I process "parse" data blocks ? any libraries, solutions ?
3. Any advice how to make it KISS ?


Thanks!

Hello!

Bitcoin RPC return message like this - Nonzero exit code: 3

Could you please recommend link with all "Nonzero exit code: 3" for bitcoin ?

Thanks!

you can find all rpc error codes in  src/rpc/protocol.h

Thanks, yes, but how about detailed description ?
for example

RPC_TYPE_ERROR                  = -3,  //! Unexpected type was passed as parameter

Can I find more details about error code ?

Re: How to calculate and add FEE

How to calculate size. found


in*180 + out*34 + 10 plus or minus 'in'
For example, this transaction has 40 inputs and 16 outputs. That gives us a transaction size of

40*180 + 16*34 + 10 +- 40
i.e. 7754 +- 40 bytes. The actual size is 7761 bytes.

Could you please clarify about  +- 40

Thanks, read this.
But that article describes how to prepare RAW tx only with one multi-signature address.

How can I create RAW TX and sign it with a few addresses

multisigAddress1
multisigAddress2

Any examples ?

RAW TX with multisignature
by

on 02/12/2015, 11:12:22 UTC
hello!

I have a few multi-signature addresses, and want to send from that addresses coins

For example if I want to spent coins from one 3 of 2 address

Prepare raw TX like this

Code:
signrawtransaction
'rawTxHex'
'[{"txid":"id","vout":1,
"scriptPubKey":"key",
"redeemScript":"redem"}]' '[[b]"priv_key","priv_key[/b]"]'

What should I do if I want to prepare Raw TX from many addresses to the one destination address ? how can I sign it ?

Any examples ?

Thanks.
