06:10 dermoth Hummmmm I'm not able to find the right way to compute vsize on segwit transactions... is there any example out there? ( I can't even seem to find which BIP defines it)
06:14 dermoth Ah nm found my error... was adding 200 instead of the full tx len :)
12:30 BW^- gmake:ing bitcoinD 0.14.2 (UASF): "*** Warning: This system can not link to static lib archive secp256k1/libsecp256k1.la.
12:30 BW^- *** I have the capability to make that library automatically link in when
12:30 BW^- *** you link to this library. But I can only do this if you have a
12:30 BW^- *** shared version of the library, which you do not appear to have."
12:30 BW^- umm
12:30 BW^- wtf
12:31 BW^- oh it built. hm.
12:31 BW^- let's see if it works.
12:33 BW^- ah, failure via FailRandom(), https://github.com/UASF/bitcoin/blob/0.14-BIP148/src/random.cpp - someone has wiped the OS logics for the same, sigh.
12:34 BW^- https://github.com/bitcoin/bitcoin/blob/master/src/random.cpp - they use another version. weird.
12:43 BW^- sigh, https://github.com/UASF/bitcoin is behind the Bitcoin mainchain, so its src/random.cpp is heavily out of date.
17:58 dermoth hey there... anyone has handy a few segwit transactions where I could link outputs to inputs?
17:59 dermoth i.e. sample transactions... signed, as they would appear on mainnet
18:00 dermoth or testnet
21:35 dakk Hi, I'm writing a library to parse/serialize bitcoin related data-structures with OCaml (https://github.com/dakk/bitcoinml/); I'm stuck trying to find some examples of hex encoded segwit transactions, someone can help me?
