This is a greatly simplified and slightly tweaked version of
af2e3713e2
Their version will detect duplicate zkproofs across transactions while
this code will only detect duplicate zkproofs in a single ztx. If dupes
are found, the tx will be denied entry into the mempool.
This provides most of the benefit (increased CPU cost to attackers) with the
least code change and no annoyance to full node operators. Detecting
duplicate zkproofs across transactions requires a one-time reindex of
all of history, which means significant downtime for nodes.
Since Hush + HSCs have a much more strict policy on number of shielded
outputs and shielded inputs, only detecting duplicate zkproofs in
individual ztxs seems sufficient for now.
No correctly functioning node or wallet will ever create duplicate
zkproofs, so there is no worry of this accidentally affecting normal
users. Currently this is not a consensus rule but it could become one
in the future.
Hush
What is Hush?
Hush implements Extreme Privacy via blockchain tech. We have our own genesis block. We are not a chain fork (copy) of another coin. We are based on Bitcoin code, with sophisticated zero-knowledge mathematics added for privacy. This keeps your transaction metadata private!
This repository
This software is the Hush node and command-line client. It downloads and stores the entire history of Hush transactions; depending on the speed of your computer and network connection, it will likely take a few hours at least, but some people report full nodes syncing in less than 1.5 hours. A competing privacy coin takes over 24 hours to sync their full nodes because of Sprout Transactions, lulz.
BANNED BY GITHUB
In working on this release, Duke Leto was suspended from Github, which gave Hush developers the impetus to completely leave that racist and censorship-loving platform.
Hush now has it's own git.hush.is Gitea instance, because we will not be silenced by Microsoft.
All Hush software will be released from git.hush.is and hush.is, downloads from any other domains should be assumed to be backdoored.
Hush is unfinished and highly experimental. Use at your own risk! Just like Bitcoin.
