[Bitcoin-development] determining change addresses using the least significant digits
Hi there, traditionally, the Bitcoin client strives to hide which output addresses are change addresses going back to the payer. However, especially with today's dynamically calculated miner fees, this may often be ineffective: A user sending a payment using the Bitcoin client will usually enter the payment amount only up to the number of digits which are considered to be significant enough. So, the least significant digits will often be zero for the payment. With dynamically calculated miner fees, this will often not be the case for the change amount, making it easy for an observer to classify the output addresses. A possible approach to handle this issue would be to add a randomized offset amount to the payment amount. This offset amount can be small in comparison to the payment amount. Any thoughts?

Re: [Bitcoin-development] Merged mining a side chain with proof of burn on parent chain
Hi there, comments in-line: I later wrote up the idea in the context of adding Zerocoin to Bitcoin: http://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/msg02472.html For the sake of maximum clarity with respect to modelling the value of a Bitcoin, I don't think that approaches which change the number of coins that can possibly be circulated should be encouraged. So, I like the idea of having the sacrificed coins appearing in the mining fees in a future block. But what is meant with OP_DEPTH in this context? From what I read, this operation just manipulates the stack size when evaluating the script, so I don't see how it would affect miner incentives.
