Coins have to get initially distributed somehow, and a constant rate seems like
the best formula.

It's not a problem if transactions have to wait one or a few extra cycles to
get into a block.

I'd like to call an end to the bitcoin e-cash discussion for now -- a
lot of discussion is happening that would be better accomplished by
people writing papers at the moment rather than rehashing things back
and forth. Maybe later on when Satoshi (or someone else) writes
something detailed u
basis,
and nodes can leave and rejoin the network at will, accepting the
longest proof-of-work chain as proof of what happened while they
were gone.

With the transaction fee based incentive system I recently posted, nodes would
have an incentive to include all the paying transactions they receive.

nce a transaction is hashed into a link that's a few links back in
the chain, it is firmly etched into the global history.

needed. It's based on open market competition, and there will
probably always be nodes willing to process transactions for free.

transaction comes back double-spent. If it's website access,
typically it wouldn't be a big deal to let the customer have access
for 5 minutes and then cut off access if it's rejected. Many such
sites have a free trial anyway.

Every transaction is one of these. Section 9, Combining and Splitting Value.

I appreciate your questions. I actually did this kind of backwards. I had to
write all the code before I could convince myself that I could solve every
