How to discover startup flags or command-line options for bitcoind? I'd like to query the Bitcoin daemon (bitcoind) to find out what startup flags (command-line options) were sent to it on startup (or the current state if it has changed, e.g. -server=0/1 changing). For example, I may want to know if -addresstype, -disablewallet, -rescan, or -uacomment=<cmt> or some other flag has been set. Or for Namecoin, it would be very useful to know if -namehistory has been set. Is there an RPC or any other method to find out? Or, to ask the question a different way... src/bitcoind.cpp's bool AppInit(int argc, char* argv[]) method calls ParseParameters(argc, argv);, which is in src/util.cpp. In src/util.cpp we have: map<string, string> mapArgs; static map<string, vector<string> > _mapMultiArgs; const map<string, vector<string> >& mapMultiArgs = _mapMultiArgs; To store flags/options/args. I'd basically just like to get whatever is in tho...

Bitcoin HD Wallets with hardened derivation and watch-only addresses I'm learning about the details of how HD wallets work. After reading the BIP32 and BIP44 documents thoroughly and supplementing it with Mastering Bitcoin there's still on aspect that I can't figure out. Say I derive an extended private key with the BIP44 first account, first address path path: m/44'/0'/0'/0/0 and then I convert the extended private key into an extended public key. Based on what I've read so far proper way would be to take the extended public key and work with an entirely non-hardened path like: M/0/1 , M/0/2 ? Is this the correct way to do it ? My problem is that a public key of M/44'/0'/0'/0/1 will not be the same as M/0/1. I'm just trying to make sure I'm using the derivation paths correctly. Thanks a lot! http://bit.ly/2DpBKlI
