📝 Original message:I'm a big proponent of a testing project.
I think if one could self organize that Gavin and team wanted to bless we
could put up some BTC as bounties or funding. We won't have our heads
around the foundation budget for a few more weeks, but self-organization is
often slower than budgeting. :)
This is just my opinion, but I would like very, very much to move the
current specification into unit tests so that anyone could validate their
alternate bitcoin implementation. This is a lot of work, some of which has
been done, much of which hasn't.
So, my two cents, plus an offer to bring it up at our next budgeting
meeting.

📝 Original message:We just implemented our own mining tool, soup-to-nuts, and I would say that
the likely motivation for what I presume are botnet owners is just economic.
It's a lot more work to make sure your merkleing and keeping up-to-date are
happening than it is to just get an 80 byte header from a central server,
and re-calc a single transaction merkle client-side.
Not to mention the extra work to keep track of what version of
getmemorypool output you're receiving work for in a broadly distributed
pool.
For what it's worth, we did this extra engineering work since we care about
Bitcoin, but if I just wanted to pull value out of the ecosystem, we would
have skipped it.
The only solutions to this are economic solutions -- making such 'cheater'
blocks less valuable, or increasing the value of the transactions.
Also note that botnet operators likely care, in the end, about fiat
currency, so going to 25 btc per block in what I think of as transaction
fee subsidies won't necessarily impact this -- it's a matter of what
happens to exchange rates vs generation rates that will matter.
I think we also have to moderate this consideration against the rights (and
arguable benefits) of someone wanting to build an express-delivery mining
service, one that will provide provably faster certification for those
adding a transaction fee of, say, 1 btc.
My own experience now in the MMO world is that we have to carefully
understand how we deal with griefers who control massive resources (compute
or gold-farmers). It may not be a winning battle to choose a solution which
harms the rest of the network in exchange for harming the griefers.
This is definitely out of the box, but one solution might be to change the
difficulty calculations to just ignore 1tx blocks; that would minimize
impact on others to a great extent, and would let someone set up an express
block service if they chose. I guess we'd have to settle on whether or not
such blocks counted towards the issuance countdown as well. Or, we could
allow only 1/10 generation fees on such blocks.
