+ * 2. The node operator hands this transaction to Alex, who then gives it to the council to sign
+ * 3. When signed and submitted, the server will verify that account 2 keys have signed, and the keys on the operator account have signed.
+ * Hedera council should have ability to make all edits in addition to add/remove nodes
