[ZcF-general] Riemann status update

[James Prestwich]

Hi All,

We wrote a brief transaction parsing and manipulation example
<https://github.com/prestwich/riemann/blob/master/riemann/examples/sapling_tx_parsing.py>.
Riemann tx objects parse ever documented Sapling tx datastructure. Each
element of each input, output, joinsplit, and shielded spend/output is
available for inspection and manipulation.

We recently wrote a Bitcoin light client called zeta
<https://github.com/summa-tx/riemann-zeta> using Electrum servers. If Zcash
Electrum makes good progress, it can be easily extended to support Zcash
main and testnets as well.

We are continuing to look for support on proof validation tools.

Best,
James
