Storage Server Donations
|
|
========================
|
|
|
|
The following is a configuration convention which allows users to anonymously support the operators of storage servers.
|
|
Donations are made using `Zcash shielded transactions`_ to limit the amount of personal information incidentally conveyed.
|
|
|
|
Sending Donations
|
|
=================
|
|
|
|
To support a storage server following this convention, you need several things:
|
|
|
|
* a Zcash wallet capable of sending shielded transactions
|
|
(at least until Zcash 1.1.1 this requires a Zcash full node)
|
|
* a shielded address with sufficient balance
|
|
* a running Tahoe-LAFS client node which knows about the recipient storage server
|
|
|
|
For additional protection, you may also wish to operate your Zcash wallet and full node using Tor.
|
|
|
|
Find Zcash Shielded Address
|
|
---------------------------
|
|
|
|
To find an address at which a storage server operator wishes to receive donations,
|
|
launch the Tahoe-LAFS web UI::
|
|
|
|
$ tahoe webopen
|
|
|
|
Inspect the page for the storage server area.
|
|
This will have a heading like *Connected to N of M known storage servers*.
|
|
Each storage server in this section will have a nickname.
|
|
A storage server with a nickname beginning with ``zcash:`` is signaling it accepts Zcash donations.
|
|
Copy the full address following the ``zcash:`` prefix and save it for the next step.
|
|
This is the donation address.
|
|
Donation addresses beginning with ``z`` are shielded.
|
|
It is recommended that all donations be sent from and to shielded addresses.
|
|
|
|
Send the Donation
|
|
-----------------
|
|
|
|
First, select a donation amount.
|
|
Next, use a Zcash wallet to send the selected amount to the donation address.
|
|
Using the Zcash cli wallet, this can be done with commands like::
|
|
|
|
$ DONATION_ADDRESS="..."
|
|
$ AMOUNT="..."
|
|
$ YOUR_ADDRESS="..."
|
|
$ zcash-cli z_sendmany $YOUR_ADDRESS "[{\"address\": \"$DONATION_ADDRESS\", \"amount\": $AMOUNT}]"
|
|
|
|
Remember that you must also have funds to pay the transaction fee
|
|
(which defaults to 0.0001 ZEC in mid-2018).
|
|
|
|
Receiving Donations
|
|
===================
|
|
|
|
To receive donations from users following this convention, you need the following:
|
|
|
|
* a Zcash shielded address
|
|
|
|
Configuring Tahoe-LAFS
|
|
----------------------
|
|
|
|
The Zcash shielded address is placed in the storage server's ``nickname`` field.
|
|
Edit ``tahoe.cfg`` and edit the ``nickname`` field in the ``node`` section like so::
|
|
|
|
[node]
|
|
nickname = zcash:zcABCDEF....
|
|
|
|
Then restart the storage server.
|
