  8 2018-12-25T00:53:52  <gmaxwell> sipa: I think we're more likely to remove GBT entirely in favor of e.g. Betterhash (which always knows the coinbase size exactly when it makes the template) than significantly change how GBT works relative to space reserved.

 89 2018-12-25T16:36:22  <Guest14218> I just want to drop two ideas here, what would make a difference in the future of bitcoin and crypto in general. 1. Solving real world problems through mining, like miners being tied to BOINC projects, so all the computing power is put to good use. 2. Wallets with AI budgeting, that takes care of your money for you, learns your expenses, auto-allocates budgets for economies, has investment schemes for low, medium and hig
 90 2018-12-25T16:36:40  <Guest14218> These 2 will give bitcoin and crypto the edge it needs over banks.

117 2018-12-25T20:38:36  <jimmysong> question about neutrino: is there a way to get the input script pubkeys with a network message?
118 2018-12-25T20:39:25  <jimmysong> if not, would it make sense to make those available with the block download to make sure the filter hash matches?
119 2018-12-25T20:39:46  <jimmysong> the client can also validate the script part of every transaction input
120 2018-12-25T20:40:09  <jimmysong> this is getting input script pubkeys for all the transactions for a given block

145 2018-12-25T23:49:35  <harding> jimmysong: when a node is validating a newly received block, it gets the prevout scripts (what I think you're calling input script pubkeys) from its utxo set.  After the block has be verified, the now-spent UTXOs are purged from the set and the node no longer has fast access to them, so it can't provide the info you want.  Furthermore, for a third party to verify that the prevout hasn't been tampered requires getting the whole
146 2018-12-25T23:49:35  <harding> transaction that contained that prevout to check its txid against the outpoint (txid:vout).  Since the max size of a tx is almost the max size of a block, that means you might need to download data equal to as many blocks as a block can have inputs (~16,000 maybe, times 4MB, or ~64GB), making this method impractical in pathological cases.
147 2018-12-25T23:53:38  <jimmysong> i guess i have to wait for a cfilter coinbase commitment then?
148 2018-12-25T23:53:46  <jimmysong> it would be nice to be able to verify a specific hash
149 2018-12-25T23:54:11  <jimmysong> though now that i think about it, you're not giving away much info by requesting *every* transaction from the inputs to a block
