+
+#### Pegging Out ####
+
+# This command would trigger watchmen to send payment to Bitcoin address on mainchain
+# The Bitcoin-side functionality is not supported directly in Elements.
+# The watchmen will notice this transaction and send the funds from their collective
+# wallet.

+
+#Exercise(s)
+#1. Implement really dumb/unsafe watchmen to allow pegouts for learning purposes
+# Recover tweak from pegin, add to privkey, combined tweaked pubkeys into a redeemscript, add to Core wallet
+
+#### RAW API ####
+
+## Let's create a basic transaction using the raw api, blind it, sign, and send
+
+# Create a transaction with a single destination output to other wallet
+rawtx = e1.createrawtransaction([], {e2.getnewaddress():100})
+# Biggest difference compared to Bitcoin is that we have explicit fee outputs
+rawtx2 = e1.createrawtransaction([], {e2.getnewaddress():100, e1.getnewaddress():5, "fee":Decimal("0.1")})
+# Fee outputs are unblinded, with a scriptPubKey of "", in other words ""
+# scriptPubKeys are unspendable
+
+# Next we can fund the transaction (and replaces fee with something more appropriate)
+fundedtx = e1.fundrawtransaction(rawtx2)
+
+# Blind
+blindedtx = e1.blindrawtransaction(fundedtx["hex"])
+# *Warning*: Raw blinding logic can be quite complicated, requiring the use of `ignoreblindfails`
+# to avoid having calls fail without manually inspecting transactions in great detail.
+# In general any transaction with 2 or more outputs to blind should succeed, so adding additional
+# is one strategy to resolve this.
+
+# Sign
+signedtx = e1.signrawtransaction(blindedtx)
+
+# And send
+txid = e1.sendrawtransaction(signedtx["hex"])
+
+sync_all(e1, e2)
+
+e2.gettransaction(txid)

+#### ADVANCED OPTIONS ####

+# -policyasset=<hex> : set network fee asset type to something other than BTC

+  AuthServiceProxy has the following improvements over python-jsonrpc's
+  ServiceProxy class:
+
+  - HTTP connections persist for the life of the AuthServiceProxy object
+    (if server supports HTTP/1.1)
+  - sends protocol 'version', per JSON-RPC 1.1
+  - sends proper, incrementing 'id'
+  - sends Basic HTTP authentication headers
+  - parses all JSON numbers that look like floats as Decimal
+  - uses standard Python json lib
