full node.

+[Full nodes](https://en.bitcoin.it/wiki/Full_node) wallets are important in

+a full node wallet is your own personal goldsmith who checks for you that

Full node wallets are also important for privacy. Using Electrum under default
configuration requires it to send (hashes of) all your bitcoin addresses to some
server. That server can then easily spy on your transactions. Full node
wallets like Electrum Personal Server would download the entire blockchain and
scan it for the user's own addresses, and therefore don't reveal to anyone else

-transactions which can link the IP address of the user to the transaction. If

+* Maximally lightweight. Very low CPU, RAM and disk space requirements. Only a
+full node required.

+ * [Blocksonly](https://bitcointalk.org/index.php?topic=1377345.0)
+ * Disabled txindex
+* Scriptable transaction broadcasting. When the user click "Send" the server
+can be configured to run a system call with the new transaction:
+ * Broadcast transactions through Tor, for [resisting traffic analysis](https://en.bitcoin.it/wiki/Privacy#Tor_and_tor_broadcasting).
+ * By writing a shell script (eg. `send-tx-over-sms.sh`) the server can

* Research and develop an easier way of rescanning the wallet when blockchain
pruning is enabled. See issue [#85](https://github.com/chris-belcher/electrum-personal-server/issues/85).

* Developing some way for Electrum servers to authenticate clients, so that
Electrum Personal Server can accept connections from the entire internet but
without a fear of privacy loss.

* Dynamic adding of wallet master public keys. Perhaps by polling for changes
in the config file.
