[Bitcoin-development] Framework for modular input selection policy for Bitcoin wallets

2014-02-10 Thread Justus Ranvier
One of the areas that isn't as well developed as it could be in terms of wallet design is fine-grained control over input selection policy. Coin control is great when a human is manually crafting transactions, but that's not really a very scalable solution. The attached image is a possible way to

If you've got any ideas for a better forum, let me know. MtGox is one of the largest public faces of the code being developed here. If the public perception is that this is a bitcoin protocol flaw, then we need some damned strong and compelling public arguments about why it ain't so. But after som

I cannot judge the competence of code I've never seen, so I have no position on that. What I HAVE seen quite clearly is both overt and covert market manipulation under cover of blame for 'the developers', or 'the exchange' You're doing it yourself with the phrase 'incompetence'. When you run an

You must be new here. MtGox very rarely comments on things like this publicly, outside of irc or their website. Second, MtGox problem is a MtGox problem. You have no right to demand access to their private code. If you feel wronged as a customer, sue them. Otherwise, they have no obligation to

Hi all, I was a bit surprised to see MtGox's announcement. The malleability of transactions was known for years already (see for example the wiki article on it, https://en.bitcoin.it/wiki/Transaction_Malleability it, or mails on this list from 2012 and 2013). I don't consider it a very big problem

What is the official response from the Bitcoin Core developers about MtGox's assertion that their problems are due to a fault of bitcoin, as opposed to a fault of their own? The technical analysis preluding this mess, was that MtGox was at fault for their faulty wallet implementation. Drak --
