Sprout MPC mirror
=================

- For Sprout MPC we mirror files referenced at
  https://github.com/zcash/mpc#assets with the following SHA256 hashes:

  r1cs: 6111c2bce234867201d887170d68712c8f8785a1c97d43ab4ca540d7704ee8f7

Sapling and powers-of-tau MPC mirror
====================================

- For powers-of-tau ceremony (used in Sapling) we mirror its final
result referenced at
https://www.zfnd.org/blog/conclusion-of-powers-of-tau/ and
https://lists.zfnd.org/pipermail/zapps-wg/2018/000362.html
as well as its transcript (https://archive.org/download/transcript_201804/):

   SHA256: transcript: 605609b98e339554832394181a3aa5880c48cffb0b603ca0dd7ce47760ca2cbe

This server runs a BitTorrent client uploading the two powers-of-tau
torrents. We also provide a metalink file
powers-of-tau/transcript.meta4 for faster downloads of the 100GB
transcript file; a good command line client for metalink is "aria2".
The metalink file references the original torrent, Internet Archive
copy, and our HTTPS mirror here.

Powers of Tau attestantions are available here
https://github.com/ZcashFoundation/powersoftau-attestations
and are also posted on zapps-wg mailing list:
https://lists.zfnd.org/pipermail/zapps-wg/

- For Sapling MPC we mirror the Sapling parameters referenced at
https://z.cash/blog/completion-of-the-sapling-mpc/

See also https://lists.zfnd.org/pipermail/zapps-wg/2018/000380.html
for randomness beacon and
https://github.com/zcash-hackworks/sapling-mpc/wiki for attestations.

Sean Bowe of Zcash has written a guide to verifying powers-of-tau + Sapling MPC:
