Title: how to use wallet notify (bitcoind) ? Post by: HackerBOSS on April 19, 2016, 02:50:25 PM Hello,
how to use wallet notify (bitcoind) ? I generate new address by json-rpc.. I need update info in MySQL after 3 confirmations. how think how much need confirmations for receive payments? Title: Re: how to use wallet notify (bitcoind) ? Post by: danda on April 20, 2016, 05:25:45 AM -alertnotify=<cmd> Execute command when a relevant alert is received or we see a really long fork (%s in cmd is replaced by message)
-blocknotify=<cmd> Execute command when the best block changes (%s in cmd is replaced by block hash) -walletnotify=<cmd> Execute command when a wallet transaction changes (%s in cmd is replaced by TxID) So for individual transactions, you would want to use walletnotify, eg: Code: bitcoind -walletnotify=/path/to/script.php %s Then in script.php, you could do something like: Code: <?phpIf you are likely to have more than one tx in a given block, a more efficient way to do it can be to include the block-hash with the tx in the db, so you can look up all tx by block. Then use blocknotify instead of walletnotify. edit: and don't forget that the txid can change due to transaction malleability. Title: Re: how to use wallet notify (bitcoind) ?

Post by: belcher on April 20, 2016, 12:15:32 PM -walletnotify will run twice per transaction, when it's first seen on the network as unconfirmed, and when it gets it's first confirmation.
To track more than one confirmation you need to use -blocknotify Title: Re: how to use wallet notify (bitcoind) ?

Post by: shorena on April 21, 2016, 07:41:28 AM -snip- my script get hash, amount etc.. but i need wallet of player. There is no simple way to get the "sending address"[1]. You have to check the inputs, but more often than not there will be several inputs. Its better to let the user set an address you store in your database along with their other information. Code: txid = dc8697d1afd6c7ac2f667cd3239e19bf227a7b5ce8be64b2f8bb3c626979425b # "random" one from the block to the hash that Polyatomic posted. within decoded_tx you will find a "vin" section with a value "vout" and a txid. If you check each of the txids you will see that they have a "vout" section. The outputs that created the inputs that are used in the TX you received. Find the one where "vout" matches "n" and look up its address. In this example there are 4 inputs, all "from" the address "1NgrpJJj2PMj9RsHutVK7vf8dchcpfM4YZ", but you need to decide how you want to handle different addresses. IIRC the data is mixed formatted, arrays within JSON, but that might be different for PHP. [1] there is no such thing Title: Re: how to use wallet notify (bitcoind) ?

You cant get the users address from the blockchain, because the blockchain does not store user information. You can either guess like secondstrade etc. (bad) or ask the user. If you ask the user they will need accounts and passwords. That adds complexity to your service. Both are viable ways to handle this, depending who you ask. I personally think that the guesswork approach is a sign of a bad concept. You are transferring funds for other people, you should never have to guess where they want the funds to go. Title: Re: how to use wallet notify (bitcoind) ? Post by: danda on April 27, 2016, 10:26:43 PM WARNING: This method can go wrong if the user sent from an exchange account or some other method that the user does not directly control, or if they sent an old-style multisig tx, or a non-standard tx. It is NOT recommended. But you asked.
The basic idea is to look at the first address entry of the vout structure of the first vin of the transaction the user sent to you. ie: tx.vin[0].vout.addresses[0] This is a little convoluted to obtain with stock bitcoind, because gettransactions does not include any vout.addresses field. So we need to do it in two steps. Step 1. Code: ./bitcoin/src/bitcoin-cli getrawtransaction <txid> 1 Quote { "txid" : "...", "version" : 1, "locktime" : 0, "vin" : [ { "txid" : "<first_vin_txid>", "vout" : 0, "scriptSig" : { "asm" : "...", "hex" : "..." }, "sequence" : 0 }, ... } Notice the vout in this case is 0. So now, let's find the matching vout for <first_vin_txid>. Step 2. Code: ./bitcoin/src/bitcoin-cli getrawtransaction <first_vin_txid> 1 Ok, we find the vout where "n" matches "vout" from the vin we looked at in the orig transaction. In this case "n" and "sequence" are both 0. Therefore 1GN... is the address associated with the first input of the orig transaction. ie, this address contributed <amount> of funds. Note that: 1) There may be one vin or multiple vin in the orig tx. ie, outputs from multiple tx may have been consolidated into one. It should be relatively safe to always choose the first vin. 2) There may be multiple values in the "addresses" field, eg if type = multisig. in this case, you should probably abort. again, don't do this. ;-) but luckyb.it too, no need enter wallet.. i think that can get player wallet, but i don't know how.. do you have idea?

If multiple values in the "addresses" field, eg if type = multisig... Can i choose any address or first? Title: Re: how to use wallet notify (bitcoind) ?

I really want to study it because i want to make a website dice game or lotto game in altcoin or crypto currency.. i hope that you can finished this and give me a sample of your work too.. Thanks..

If multiple values in the "addresses" field, eg if type = multisig... Can i choose any address or first? Well, you could, but it does not seem "correct". Consider that a multisig transaction may have multiple signers. As in, different people or businesses. which is which? The safest thing is to abort in this case, and follow up with user manually. But you might not ever see this type of tx. |
