Extremely large transactions with lots of inputs can cost the network
almost as much to process as they cost the sender in fees.
We would never create transactions larger than 100K big; this change
makes transactions larger than 100K non-standard, so they are not
relayed/mined by default. This is most important for miners that might
create blocks larger than 250K big, who could be vulnerable to a
make-your-blocks-so-expensive-to-verify-they-get-orphaned attack.
- this change allows us to keep the translation without the need to
re-translate any string, when we update the copyright year
- copyright symbol is changed to HTML to ensure we get no encoding
issues and it's removed from the translation string so translators don't
break it by mistake
The current default URL doesn't seem to exist.
Unsure wether this should be updated to point to 0.7.2 now or wether
just to wait untill 0.8.0 is out and point there?
Commit also fixes a minor typo in the macdeploy notes.txt
* updated references to files which have since been moved
* added reference to licensing
* added brief summary in case a non-technical user happens upon repo first
* miscellaneous Markdown-isms to make the doc more attractive
* remove unused symlink README -> README.md
I double-checked the makefiles and whatnot to ensure that the README symlink is
not being referenced. It is not. Rather, `doc/README` and
`doc/README_windows.txt` are copied for distribution.
At least one service that accepted zero-confirmation transactions
was vulnerable because an attacker could send a transaction
with a lock time far in the future, and then have plenty of time in
which to get a double-spend mined (perhaps from a miner who wasn't
on the network when the first transaction was broadcast).
That is a variation on the "Finney attack". We still don't
recommend anybody accept 0-confirmation transactions as final
payment for anything. This change keeps non-final transactions
from appearing in the wallet, and, assuming most of the network
accepts this change, will prevent them from being relayed until
they are final.
