1 2015-03-15 10:00:39 <Muis> Did someone ever implemented this: https://en.bitcoin.it/wiki/User:DiThi/MTUT#PROPOSAL:_Merkle_tree_of_unspent_transactions_.28MTUT.29.2C_for_serverless_thin_clients_and_self-verifiable_prunned_blockchain.  ?
 2 2015-03-15 10:00:51 <Muis> and if not, is there a good reason for that?
 3 2015-03-15 10:42:31 <Adlai> Muis: generating and maintaining that datastructure places a lot of overhead on the nodes that don't really benefit from it... so there don't seem to be strong incentives towards this right now
 4 2015-03-15 10:55:21 <Muis> Adlai: thanks
 5 2015-03-15 11:57:34 <Eliel> Adlai: Implementing something like that would remove the need for full nodes to keep a full history.
 6 2015-03-15 11:58:24 <Eliel> or even, any history if you move the responsibility to store the transactions to the wallets.
 7 2015-03-15 11:59:32 <Hasimir> and almost certainly introduce other problems ...
 8 2015-03-15 12:05:41 <Eliel> I'm sure many would still archive all the transactions... especially people interested in compromising people's privacy :P
 9 2015-03-15 13:29:32 <da2ce7> hello all
10 2015-03-15 13:30:19 <da2ce7> is there any progress to start include opportunistic encryption for the bitcoin network?
11 2015-03-15 13:30:56 <da2ce7> this will make passive attacks harder.
12 2015-03-15 15:20:52 <Ostkaka> Hiamatta Hiamatta HO! HO! HO!

16 2015-03-15 23:18:00 <ahmed_> hi all
17 2015-03-15 23:18:19 <ahmed_> how do i check the fee attached to a transaction?
18 2015-03-15 23:34:22 <BladeMcCool> ahmed_: I'm a noob still but I'm pretty sure its the difference between the sum of the inputs and the sum of the outputs.
19 2015-03-15 23:34:48 <ahmed_> BladeMcCool: yeah trying to figure out how to check what the value of the inputs are
20 2015-03-15 23:35:19 <belcher> getrawtransaction(tx_id_of_input_here)
21 2015-03-15 23:35:37 <belcher> deserialize that, then look in the output of that at index vout
22 2015-03-15 23:35:43 <belcher> since an input is made up of a txid and an index
23 2015-03-15 23:36:06 <belcher> ahmed_ ^
24 2015-03-15 23:36:30 <belcher> you could also look up with a blockchain explorer, although they probably use getrawtransaction behind the scenes
25 2015-03-15 23:36:43 <ahmed_> belcher: great thanks :)
26 2015-03-15 23:49:40 <Luke-Jr> ahmed_: a given transaction has no information about its input values, and therefore it is impossible to determine the fee outside of context
27 2015-03-15 23:50:20 <ahmed_> Luke-Jr: .... so after a tx has been broadcasted onto the network theres no way to check the tx fee?
28 2015-03-15 23:51:13 <Luke-Jr> ahmed_: not from just that transaction, no; that's why only full nodes relay transactions
29 2015-03-15 23:51:48 <ahmed_> Luke-Jr: well i am running a full node. so i can just query the blockchain for the input's and then calculate the value right?
30 2015-03-15 23:52:08 <Luke-Jr> the blockchain is not queriable. you'd query the chainstate (UTXO) and mempool, though, yes
31 2015-03-15 23:52:21 <ahmed_> exactly
