Hushlist: Censorship Resistant Metadata-Minimizing Multi-Blockchain Communication

Hush, little baby, don't say a word,
Mama's going to buy you a mockingbird.
And if that mockingbird don't sing,
Mama's going to buy you a diamond ring.
And if that diamond ring turns brass,
Mama's going to buy you a looking glass.

Examples of using Hush:

# create a new Hush contact
hushlist contact add alice z123
hushlist contact add bob z456

# see an overview of your local hushlist infoz
hushlist status

# create a new private hushlist, which exists locally only
# and has no cost associated, since nothing is sent to the blockchain
hushlist new listname

# see the status of a list
hushlist status listname
hushlist add listname alice bob
hushlist send listname "A beginning is the time for taking the most delicate care that the balances are correct."

# send using a non-default chain
hushlist send listname --chain tush "If wishes were fishes, we'd all cast nets. -- Stilgar"

# show overview of lists and messages
hushlist log

# show most recent messages for listname
hushlist log listname

# donate 5 HUSH to the nice dev Duke Leto who write this software
hushlist donate 5 hush

In development commands

This will rely on z_embedstring RPC which will hopefully be in the Hush 1.0.13 release, it is currently in the dev branch:

# make an already created private hushlist PUBLIC, i.e.
# publish it's privkey to the blockchain. This costs HUSH, since
# we need to send an xtn to the blockchain
hushlist public listname
