The BitHalo / BlackHalo multi-sig smart contracting wallet is out. I can’t believe that I missed it but after having posted about the BitBay Halo update I could have figured that Halo2 was out for Blackcoin and Bitcoin as well. The cool part is, Halo2 comes with BTC and BLK support (multi-coin wallet).
The wallet uses multi-sig for all addresses and you can now also embed your keys into 2 different images, store those separately and restore your wallet(s) at any time by loading the image files. Love that!
You can switch between BTC and BLK with one single click and create offers on the decentralized marketplace, trustless coin exchange through double deposit escrow and the client also allows for secure multi-sig joint account.
There is much more to it and I’m still syncing both chains but here some screenshots.
Also, we tested the contracts in Linux and that build is now working. I did a fix to highlevelcrypto so now it works in Linux and Mac. So that is what we are working on and expect that to be available soon. Again Mac and Linux users, excuse the delay, being the only coder I had to make sure we solved some of the user friendliness first.
The home screen (the same for BTC or BLK)
Send Screen including “two step send”
Two step send is used for joined accounts. Typically you would put in your private key and link it up with the other persons public key. He will then receive a request to authorize the transaction and confirm by linking his private key with your public key on his end.
Receive a payment
This tab also contains the options for Bitmessage or email which is required for smart contracts or two step payments. I don’t use Bitmessage since the protocol itself used to be quiet bugged and I’m not sure if it has been fixed. Instead I’ve setup a gmail address that I only use for Halo. The reason being that you need to authenticate with google by entering your password.
Thus if you want to be on the safe side, just create a new gmail account and add the profile to your chrome so you can switch between your accounts.
Integrated Irc chat
Smart Contracts tab
This is where the magic happens. Unbreakable smart contracts and trustless double-deposit escrows with time stamp and so on. I’m looking forward to chat about this
Decentralized Marketplace (not live yet)
NightTrader decentralized marketplace. Trade pretty much anything with anyone without every needing an escrow again.
I can only recommend to at least download Halo to check it out. It’s currently not my main wallet but it might be very soon. At the latest when Blackcoin support for colored coins.
