I tried figuring out how to redeem them, but couldn't get any transactions to be accepted by sendrawtransaction or https://blockchain.info/pushtx even through decoderawtransaction made me think I was doing it right.

But somebody figured out how to take the coins: https://blockchain.info/tx-index/36395409?show_adv=true

Looks like that person screwed up though, see tx af32bb06f12f2ae5fdb7face7cd272be67c923e86b7a66a76ded02d954c2f94d Same idea, but an earlier attempt with the wrong endian and hence unspendable.

The one with the correct endian has been spent by tx 09f691b2263260e71f363d1db51ff3100d285956a40cc0e4f8c8c2c4a80559b1 Curiously I'm seeing it as unconfirmed right now, which implies that either that Blockchain.info has a server ignoring the IsStandard check or it does in fact pass. For a scriptSig input, as opposed to a scriptPubKey output the actual check is AreInputsStandard, although looking at that code I don't see how it could have passed the test. The transaction also hasn't propagated to any of my Bitcoin nodes, which implies the former explanation.

EDIT: oops, didn't see you saying you sent that TX... you might also want to try re-sending it directly to Eligius, who accept non-standard TX's for mining. See the wiki page Free transaction relay policy. I think you can trigger that resend by re-running sendrawtransaction

That block has another interesting set of transactions; e1a1a0242d46fb515a3aaaef713104832384a0f30a4fcdfefb982d1c06e56860 is one example. p2pool includes a zero-valued output in every one of their coinbase transactions that just pushes the hash of the current share in the p2pool sharechain to the stack. While zero-valued those outputs are spendable as they are evaluated to true. Looks like this person has gone off and found every (?) such p2pool output and spent it. With pruning that's actually kind-of a public service by reducing the tx-out set...


They'd also make good examples for the wiki.

Interesting! So how exactly do you do to complete the transaction?

As I said, get it to a miner who will mine it. According to the wiki Eligius will, so use -addnode=173.242.112.53 or post the raw hex for your transaction here and I'm sure someone will be able to forward it for you.


Doesn't look like it. The scriptPubKey consists of a single OP_TRUE opcode, while the createrawtransaction command only allows you to specify outputs as valid addresses, or nothing at all. The latter would leave scriptPubKey totally empty.

Yeah, but in this case anyone can trivially replicate the transaction already anyway. It's just a race to see who gets it mined first. Heck, I'd do it myself, but sebicas was pretty clever for figuring it out so I think he deserves the BTC a lot more than I do.

I saw this post yesterday just before going to bed and was going to claim it first thing in the morning (was dead tired), now it is taken. You snooze you loose 

I know that output 0 of transaction cdb553214a51ef8d4393b96a185ebbbc2c84b7014e9497fea8aec1ff990dae35 was already claimed, but this post triggered me to experiment with manually constructing transactions.

Here is a piece of code that uses bitlib and bccapi to build the exact same transaction:
http://code.google.com/p/bccapi/source/browse/trunk/bccapi/src/com/bccapi/ng/example/CustomBuiltTransaction.java

Here is the gist:
   public static void main(String[] args) throws ScriptParsingException, MalformedURLException, ApiException {
     / Build transaction input
      Sha256Hash txHash = new Sha256Hash(
            HexUtils.toBytes("cdb553214a51ef8d4393b96a185ebbbc2c84b7014e9497fea8aec1ff990dae35"));
      OutPoint outPoint = new OutPoint(txHash, 0);
      ScriptInput si = ScriptInput.fromScriptBytes(new byte[] { 1, Script.OP_FALSE, Script.OP_DROP });
      TransactionInput ti = new TransactionInput(outPoint, si);

     / Build transaction output
      Address receiver = Address.fromString("1LqTjBzMRdXQqXpRQo1zDYRiUobAVS55Lo", NetworkParameters.productionNetwork);
      ScriptOutput so = new ScriptOutputStandard(receiver.getTypeSpecificBytes());
      TransactionOutput to = new TransactionOutput(99950000, so);

     / Build transaction
      Transaction tx = new Transaction(1, new TransactionInput[] { ti }, new TransactionOutput[] { to }, 0);
      System.out.println("Our transaction hash: " + tx.getHash().toString());

     / Broadcast transaction (here we depend on the BCCAPI server, you can use
     / whatever API you like for this)
      URL url = new URL("http://bqs1.bccapi.com:80");
      BitcoinClientApi api = new BitcoinClientApiImpl(url, NetworkParameters.productionNetwork);
      BroadcastTransactionResponse response = api.broadcastTransaction(new BroadcastTransactionRequest(tx));
      System.out.println("Broadcasted transaction with hash: " + response.hash.toString());
   }


Hope you find it useful.
