Instead of thinking in terms of blocking uneconomical transactions (how
would a node even determine what's economical?), what about thinking in
terms of paying for a feed of economical (i.e. profitable) transactions?
There is a market for fee bearing, profitable transactions...if there is no
one willing to pay to receive a transaction, then no one will bother
propagating it. Such a system would make it possible to determine the
probability of confirmation in a given timeframe for a given fee.

</div>There's been a lot of discussion about this issue, and many peopl=
e have<br>
asked that Bitcoin not arbitrarily block interesting potential uses of<br>
provably unspendable txouts for data applications, and similarly<br>
spendable txouts representing assets. I've changed my hardline position=
<br>
and now think we should support all that stuff. However, there is one<br>
remaining class of txout not yet talked about, unspendable but not<br>
provably so txouts. For instance we could make the following a standard<br>
transaction type:<br>
<br>
scriptPubKey: OP_HASH160 <20 byte digest> OP_EQUALVERIFY <data>=
<br>
scriptSig: <data><br>
<br>
Of course, usually the 20 byte digest would be picked randomly, but it<br>
might not be, and thus all validating nodes will always have a copy of<br>
the data. With the 10KB limit on script sizes you can fit 9974 bytes of<br>
data per transaction output with very little waste.<br>
<br>
A good application is timestamping, with the advantage over<br>
coinbase/merkle tree systems in that you don't have to wait until your<=
br>
timestamp confirms, or even store the timestamp at all. Another<br>
application, quite possible with large block sizes and hence cheap or<br>
free transactions, is secure data backups. In particular such a service,<br>
perhaps called Google Chain Storage, can offer the unique guarantee that<br>
you can know you're data is secure by simply performing a successful<br>
Bitcoin transaction.<br>
