soon I'm going to be removing the old electrum deterministic wallet commands. people should switch to using the newer HD commands which all wallets (electrum included) are adopting.

I want to add Litecoin and Dogecoin to libbitcoin. Might be a month or so before it happens, but we want this in DW and SX.
Right now I have to focus on optimising the blockchain.

In the install-sx.sh script, in the function called install_libbitcoin, change ./configure with --enable-testnet I think I did that. Also added "--enable-testnet" for libwallet I'm looking at config.log in libbitcoin-git and libwallet-git - they both show "ENABLE_TESTNET 1" But the "sx stealth-show-addr" still says "Invalid stealth address" for any testnet stealth. At the other hand it has no problems to decode a non-testnet stealth addresses. EDIT: I think I know where is the problem. In libwallet-git/src/stealth.cpp, there should be: #ifdef ENABLE_TESTNET
constexpr uint8_t stealth_version_byte = 0x2b;
#else
constexpr uint8_t stealth_version_byte = 0x2a;
#endif
I added that in git. Also now there is a --develop switch: bash install-sx.sh PREFIX --develop |

btw, can I have the sx tools for testnet? the ones I finally managed to build cannot even do $ sx stealth-show-addr waPV5rHToBq3NoR7y5J9UdE7aUbuqJybNpE88Dve7WgWhEfvMrcuaSvF6tSQ3Fbe8dErL6ks8byJPcp3QCK2HHviGCSjg42VgMAPJb
sx: Invalid stealth address. In the install-sx.sh script, in the function called install_libbitcoin, change ./configure with --enable-testnet this line: https://github.com/spesmilo/sx/blob/master/install-sx.sh#L313install_libbitcoin(){
...
./configure --enable-leveldb --prefix $INSTALL_PREFIX --with-libsecp256k1=$INSTALL_PREFIX --enable-testnet
...
}

Yep, I saw it already - thx.
But it seems to be already working well in my s/w (sending and receiving).
I can exchanging coins via stealth addresses with DW - don't need sx for it anymore.
Unfortunately sx nor DW support stealth addresses with non-zero length prefixes ATM, so I cannot test that part of mine.
But zero length prefixes seem to work just fine.
correct. glad to hear that. |

I want to clear up some facts which I'm seeing propagated around this community about the CoinJoin trustless mixing used in Dark Wallet. Dark Wallet coinjoin goes through a server, but the server cannot see any details of your transaction nor can they steal your coins. All details are encrypted for the counterparty, and all signing happens in the client. The only weakness here is that a server gets taken down stopping the service in which case you switch to another service. Even if the NSA controlled the server, they wouldn't be able to steal your coins or observe your transaction at all. Lastly the server is sharing messages with other servers (we are improving this too), so it isn't really centralised. It is federated kind of like how different email providers inter-operate with each other. The decentralised aspect will only improve over time as we develop standards and deploy technology. More info: https://bitcointalk.org/index.php?topic=279249.msg6526623#msg6526623DW dev |

piotr you will need to eventually upgrade anyway  we're on freenode irc #darkwallet too if you have any questions https://webchat.freenode.net/ or use XChat I'm currently improving the stealth commands in SX then will merge to master after. |

Terrorist is in the eye of the beholder. It's a term that has been used to. Bitcoin is in fact not anonymous. The entire ledger of every transaction ever made since its inception is publicly replicated online, it's probably the least anonymous system ever created and used.
blaa blaa keep trotting this tired and untrue lie like a parrot. bitcoin can be very anonymous, and will only get more so as we make the tools more user friendly. this propaganda is spoonfed to people on a plate of bitcoin legitimisation and acceptance. you are being manipulated for some group's own ends. |

good idea, i'll ask the other wallets about something like this. it should be fair and open though.

@dabura667 cheers. so the prefix length cannot be bigger than 32 bits? and if it was all 32 bits, but I could not find a matching nonce - what then? pick up a different "ephemkey"? @genjix yeah, I had gone through these specs. none of them was even close to be as useful as one post from dabura667  btw, building the tools on my old ubuntu 12.04 was a real fight. first I needed gcc 4.7 (I had 4.6) then leveldb version was apparently too old and libbboost - I also had to upgrade this one to 1.49. the biggest problem was that the errors I saw did not help much to diagnose the problems. the second biggest: this version of ubuntu would not just upgrade any of these packages in a simple way. cmon man upgrade your ubuntu. that is super old! ubuntu 14 is a new LTS |
