Title: coalesced transactions, is it possible? why want?
Post by: radixprax on November 08, 2014, 06:28:31 PM

I have thought a good deal about a way for those who receive donations ( or any form of regular voluntary funds ) to overcome the accounting / regulatory burdens of micro-transactions. With crypto-currencies as an option, I think it opens up some innovative solutions.

The solution I imagined was if transactions could be scheduled for a specific time and date. For some accounting practices I imagine this could suffice as one could record total income in a 24 hr period and not get alot of flack from auditors. But, it would be ideal I imagine if many transactions could be merged into one at a specific time and then sent to the desired destination. Is this possible with block-chain tech?

A re-statement of the question: could several transactions from several unrelated people, initiated at different times but targeted at the same time and address be coalesced into one transaction before execution, so that on the recipients end it only appears as one lump sum and transaction.

Imagine your favorite podcaster ( https://www.youtube.com/watch?v=i7gTWHebfNk ) advertising the regular time and day of the month that they would like for you to send your donations.

Thanks all

Yes, coinjoin [1], shared coin [2], darkwallet mixing [3] and many more do something similar or exactly this. The only thing thats not possible from what I read here is that you will not know in advance when exactly the TX will confirm, since you cant predict when a block will be found. As long as the time is only roughly important (e.g. after X, or any time on day Y) its fine.

...and on that hour the miners just cant find a block and any TX will have to wait for 2 hours to get a confirmation. Its rare but it happens. I dont exactly see why the time is important though.

Ah!, thank you so much Shorena. I understand  :)

Now to convince those who receive and send mTX, to practice and request large scale coin-joining.

Any recommendations on which wallet / service, I see sharedcoin might not be the best;

Currently? Id either not bother or test darkwallet with small (!) amounts. Its still alpha.
