+I released https://github.com/Ayms/bitcoin-transactions
+
+As you can see the restart of this project (started one year ago) was
+motivated by the epic launch of bitcoin gold and many people still
+desperately trying to sync, not understanding there was no need to
+'transfer' their bitcoins to btg, getting robbed, etc, but there is more
+some long term intent
+
+This is somewhere bitcoin-cli outside of bitcoin-qt with a non
+synced/outside wallet (where https://github.com/Ayms/bitcoin-wallets can
+be used), not only for btg but for any network based on bitcoin
+
+While implementing BIP143 I noticed during the tests/doublechecks with
+cli that scriptSig was <signature>< pubkey>
+
+This was not the case one year ago, scriptSig was <signature> since you
+can get the <pubkey> from the signature, that's what I did thinking of
+some lack of optimization in the bgold client, but this behavior is very
+the same for bitcoin core
+
+Then my first transactions did not include the pubkey and I was
+immediately banned by my own node (who btw did not realize that it was
+banning itself...), I got a reject message stating that OP_EQUALVERIFY
+failed
+
+So, the questions are: for basic p2pkh transactions why is pubkey back,
+since when and why txs without it are rejected?
+
+At this time where everything is made to reduce the tx's size while the
+fees/byte are quite high, this adds 34 useless bytes in each input
