Maybe you should take a break from implementing stuff until this innovation-storm settles down

Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet

on: June 24, 2015, 08:19:44 AM

I have recently installed mycelium on my phone, but am having some issues regarding privacy. I want to restore my old wallet, but before I do I want to enable syncing the wallet via tor. This is not possible AFAIK. I tried doing a workaround by creating a new wallet, enabling tor and then restoring my backup, but I cannot find any way to restore a backup after I have created a new wallet.

Bitcoin / Armory / Re: Two questions: Trezor and libbitcoinconsensus

on: January 17, 2015, 06:25:53 PM

Yeah I don't think libbitcoinconsensus will be ready anytime soon. From what I understand it is just a first step with the 0.10 release and more needs to be done. I was merely wondering if you had planned (or at least thought about) ditching core when it is finished and deemed safe to use. Good to know that you are thinking about it

Bitcoin / Armory / Two questions: Trezor and libbitcoinconsensus

on: January 17, 2015, 10:10:52 AM

1. Long time ago since I heard about trezor compatability in armory. How is it going? 2. Will Armory eventually use libbitcoinconsesus and ditch the dependency it has on bitcoin core?

Is this implemented in any current PoS systems?

Bitcoin / Development & Technical Discussion / A(nother) downside to Proof-of-Stake?

on: October 30, 2014, 09:48:33 AM

Please correct me if I'm wrong, but doesn't PoS require the miners to keep their private keys online on the machine doing block validation? Isn't this a major security flaw, since if a vulnerability in the software is found that allows an attacker to extract the private key, he can clean out pretty much all miners wallets, making it a breeze to gain >50% stake?

Thanks for the help. There is nothing wrong with the permissions. I am able to read/write from/to the share without issues. I tried symlinking, as you suggested, but with the same results... Will definately check out the memory optimizations once I get up and running. Thanks for the tip.

I dont specify a datadir. I start bitcoind with the user bitcoin so the datadir is /home/bitcoin/.bitcoin, which is where I mount the share.

Bitcoin / Bitcoin Technical Support / Full node on a raspberry pi with blockchain data on a samba share

on: October 16, 2014, 08:17:48 PM

I am trying to get a full node running on a raspberry pi. However, because of the storage requirements I dont want to save the blockchain locally, which means I mounted a remote share which included the blockchain data files. When starting bitcoind I get the following error message:

Code:

: 
Error opening block database.

Do you want to rebuild the block database now?

More verbose from the log file:

When running bitcoind with a local datadir it runs as normal with no error message. Someone who might know what the issue might be?

I am running a slim archlinux install and mounted the remote share with:

Code:

mount.cifs //<ip-address>/bitcoin /home/bitcoin/.bitcoin -o username=<username>,uid=bitcoin

Good to know! Are there any plans for watch-only addresses?

Bitcoin / Wallet software / Re: A more configurable SPV client for Android

on: September 30, 2014, 02:31:20 PM

Thanks for the tip. Didn't know Bitcoin Wallet could do that. However last I heard Bitcoin Wallet doesn't support encryption of the private keys, HD Wallets or watch-only addresses. But good to know in case they fix those things in future updates. I was planning to connect to my node through my VPN, so no issues there.

Bitcoin / Wallet software / A more configurable SPV client for Android

on: September 26, 2014, 09:49:43 PM

I was wondering if there is any highly configurable SPV client for Android? The most important thing I want to configure is what nodes I should connect to, i.e, my own node, as this would provide me with greater financial privacy when broadcasting transactions. Or maybe if there is a client that may include this feature some day?

What is the reason for not checking the entire blockchain for UTXOs for my watch addresses? I find this very annoying in an otherwise awesome wallet.

Great! Is the increase in ScriptSig length to account for greater M and N values of M-of-N multisig transactions?
