+This project is a demonstration of the Cosmos Hub staking functionality; it is
+designed to get validator acquianted with staking concepts and procedures.
 
 Potential validators will be declaring their candidacy, after which users can
 delegate and, if they so wish, unbond. This can be practiced using a local or
 public testnet.
 
+This example covers initial setup of a two-node testnet between a server in the cloud and a local machine. Begin this tutorial from a cloud machine that you've ``ssh``'d into.
+
 Install
 -------
 
-The ``gaia`` tooling is an extension of the Cosmos-SDK; to install:
+The ``basecoind`` and ``basecli`` binaries:
 
 ::
 
-    go get github.com/cosmos/gaia
-    cd $GOPATH/src/github.com/cosmos/gaia
+    go get github.com/cosmos/cosmos-sdk
+    cd $GOPATH/src/github.com/cosmos/cosmos-sdk
     make get_vendor_deps
     make install
 
-It has three primary commands:
+Let's jump right into it. First, we initialize some default files:
 
 ::
 
-    Available Commands:
-      node        The Cosmos Network delegation-game blockchain test
-      rest-server REST client for gaia commands
-      client      Gaia light client
-                        
-      version     Show version info
-      help        Help about any command
+    basecoind init
 
-and a handful of flags that are highlighted only as necessary.
+which will output:
 
-The ``gaia node`` command is a proxt for running a tendermint node. You'll be using
-this command to either initialize a new node, or - using existing files - joining
-the testnet. 
+::
 
-The ``gaia rest-server`` command is used by the `cosmos UI <https://github.com/cosmos/cosmos-ui>`__.

+    citizen hungry tennis noise park hire glory exercise link glow dolphin labor design grit apple abandon
 
-Lastly, the ``gaia client`` command is the workhorse of the staking module. It allows
-for sending various transactions and other types of interaction with a running chain.
-that you've setup or joined a testnet.
+This tell us we have a ``priv_validator.json`` and ``genesis.json`` in the ``~/.basecoind/config`` directory. A ``config.toml`` was also created in the same directory. It is a good idea to get familiar with those files. Write down the seed.
 
-Generating Keys
----------------
+The next thing we'll need to is add the key from ``priv_validator.json`` to the ``basecli`` key manager. For this we need a seed and a password:
 
-Review the `key management tutorial <../key-management.html>`__ and create one key
-if you'll be joining the public testnet, and three keys if you'll be trying out a local
-testnet.
+::
+
+    basecli keys add alice --recover
+
+which will give you three prompts:
+
+::
+
+    Enter a passphrase for your key:
+    Repeat the passphrase:
+    Enter your recovery seed phrase:
+
+create a password and copy in your seed phrase. The name and address of the key will be output:
+
+::
+
+    alice           67997DD03D527EB439B7193F2B813B05B219CC02
+
+You can see all available keys with:
+
+::
+
+    basecli keys list
+
+See the `key management tutorial <../key-management.html>`__ for more information on managing keys.
 
 Setup Testnet
 -------------
 
-The first thing you'll want to do is either `create a local testnet <./local-testnet.html>`__ or
-join a `public testnet <./public-testnet.html>`__. Either step is required before proceeding.
+Next, we start the daemon (do this in another window):
 
-The rest of this tutorial will assume a local testnet with three participants: ``alice`` will be
-the initial validator, ``bob`` will first receives tokens from ``alice`` then declare candidacy
-as a validator, and ``charlie`` will bond then unbond to ``bob``. If you're joining the public
-testnet, the token amounts will need to be adjusted.
+::
+
+    basecoind start
+
+and you'll see blocks start streaming through.
+
+For this example, we're doing the above on a cloud machine. The next steps should be done on your local machine or another server in the cloud, which will join the running testnet then bond/unbond.
+
+Accounts
+--------
+
+We have:
+
+- ``alice`` the initial validator (in the cloud)
+- ``bob``  receives tokens from ``alice`` then declares candidacy (from local machine)
+- ``charlie`` will bond and unbond to ``bob`` (from local machine)
+
+Remember that ``alice`` was already created. On your second machine, install the binaries and create two new keys:
+
+::
+
+    basecli keys add bob
+    basecli keys add charlie
+
+both of which will prompt you for a password. Now we need to copy the ``genesis.json`` and ``config.toml`` from the first machine (with ``alice``) to the second machine. This is a good time to look at both these files.
+
+The ``genesis.json`` should look something like:
+
+::
+
+    {
+      "app_hash": "",
+      "app_state": {
+        "accounts": [
+          {
+            "address": "1FEADCDC8CCB22244769B9CC93C1F6D7489FC5AF",
+            "coins": [
+              {
+                "denom": "mycoin",
+                "amount": 9007199254740992
+              }
+            ]
+          }
+        ]
+      },
+      "chain_id": "test-chain-EsYka3",
+      "genesis_time": "0001-01-01T00:00:00Z",
+      "validators": [
+        {
+          "pub_key": {
+            "type": "ed25519",
+            "data": "57B89D41F18FE3FE69250B44693A7D68DE4E03EC563F54C27F9A86CE8B81A4B7"
+          },
+          "power": 10,
+          "name": ""
+        }
+      ]
+    }
+
+To notice is that the ``accounts`` field has a an address and a whole bunch of "mycoin". This is ``alice``'s address (todo: dbl check). Under ``validators`` we see the ``pub_key.data`` field, which will match the same field in the ``priv_validator.json`` file.
+
+The ``config.toml`` is long so let's focus on one field:
+
+::
+
+    # Comma separated list of seed nodes to connect to
+    seeds = ""
+
+On the ``alice`` cloud machine, we don't need to do anything here. Instead, we need its IP address. After copying this file (and the ``genesis.json`` to your local machine, you'll want to put the IP in the ``seeds =  "138.197.161.74"`` field, in this case, we have a made-up IP. For joining testnets with many nodes, you can add more comma-seperated IPs to the list.
+
+
+Now that your files are all setup, it's time to join the network. On your local machine, run:
+
+::
+
+    basecoind start
+
+and your new node will connect to the running validator (``alice``).

+# Cosmos Testnet Setup
+
+## Installment
+
+Requirement :
+
+ [Go 1.9+](https://golang.org/dl/)
+
+ [dep](https://github.com/golang/dep)
+
+###  STEPS
+
+**Get Source Code**
+
+```
+go get github.com/cosmos/cosmos-sdk
+```
+
+Now we can fetch the correct versions of each dependency by running:
+
+```
+cd $GOPATH/src/github.com/cosmos/cosmos-sdk
+git fetch --all
+git checkout develop
+make get_tools
+make get_vendor_deps
+make install
+make install_examples
+```
+
+The latest cosmos-sdk should now be installed. Verify that everything is OK by running:
+
+```
+gaiad version
+```
+You should see:
+
+```
+0.15.0-rc1-9d90c6b
+```
+
+And also:
+
+```
+basecli version
+```
+
+You should see:
+
+```
+0.15.0-rc1-9d90c6b
+```
+
+### Local-Test Example
+
+Here is a quick example to get you off your feet:
+
+First, generate a new key with a name, and save the address:
+```
+MYNAME=<your name>
+basecli keys new $MYNAME
+basecli keys list
+MYADDR=<your newly generated address>
+```
+Now initialize a gaia chain:
+```
+gaiad init --home=$HOME/.gaiad1
+```
+
+you should see seed phrase for genesis account in the output & config & data folder int the home directory
+
+In the config folder, there will be the following file: config.toml , genesis.json, node_key.json ,priv_validator.json 
+
+The genesis file should look like this:
+
+```
+{
+  "genesis_time": "0001-01-01T00:00:00Z",
+  "chain_id": "test-chain-0TRiTa",
+  "validators": [
+    {
+      "pub_key": {
+        "type": "AC26791624DE60",
+        "value": "<value>"
+      },
+      "power": 10,
+      "name": ""
+    }
+  ],
+  "app_hash": "",
+  "app_state": {
+    "accounts": [
+      {
+        "address": "<ADDR>",
+        "coins": [
+          {
+            "denom": "steak",
+            "amount": 9007199254740992
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+**Note: ** We need to change the denomination of token from default to `steak` in genesis file.
+
+Then, recover the genesis account with `basecli`
+
+```
+basecli keys add <name> --recover
+```
+
+By now, you have set up the first node. This is great!
+
+We can add a second node on our local machine by initiating a node in a new directory, and copying in the genesis.
+
+```
+gaiad init --home=$HOME/.gaiad2
+```
+
+Replace the genesis file and toml file to another folder
+
+```
+cp $HOME/.gaiad/config/genesis.json $HOME/.gaiad2/config
+cp $HOME/.gaiad/config/config.toml $HOME/.gaiad2/config
+```
+
+Get the node id of first node.
+```
+gaiad show_node_id --home=$HOME/.gaiad1
+```
+We need to also modify $HOME/.gaiad2/config.toml to set new seeds and ports. It should look like:
+```
+proxy_app = "tcp://127.0.0.1:46668"
+moniker = "anonymous"
+fast_sync = true
+db_backend = "leveldb"
+log_level = "state:info,*:error"
+
+[rpc]
+laddr = "tcp://0.0.0.0:46667"
+
+[p2p]
+laddr = "tcp://0.0.0.0:46666"
+persistent_peers = "<node1-ID>@0.0.0.0:46656"
+```
+Great, now that we've initialized the chains, we can start both nodes in the background:
+```
+gaiad start --home=$HOME/.gaiad1  &> gaia1.log &
+NODE1_PID=$!
+gaia start --home=$HOME/.gaiad2  &> gaia2.log &
+NODE2_PID=$!
+```
+Note we save the PID so we can later kill the processes. Of course, you can peak at your logs with tail gaia1.log, or follow them for a bit with tail -f gaia1.log.
+Nice. We can also lookup the validator set:
+
+```
+basecli validatorset
+```
+There is only **one** validator now. Let's add another one! 
+First, we need to create a new account:
+
+```
+basecli keys new <NAME>
+```
+Check that we now have two accounts:
+```
+basecli keys list 
+```
+Then, we try to transfer some `strak` to another account:
+```
+basecli send --amount=1000steak --to=$MYADDR2 --name=$NAME --chain-id=<CHAIN-ID> --node=tcp://localhost:46657 --sequence=0
+```
+**Note** We need to be careful with the `chain-id` & `sequence`
+
+Check the balance & sequence by :
+```
+basecli account $MYADDR
+```
+We can see the balance of $MYADDR2 is 1000 now. 
+
+Findally, let's bind the validator in `$HOME/gaiad2`, get the pubkey first
+```
+cat $HOME/.gaiad2/config/priv_validator.json | jq .pub_key.value
+```
+
+Go to [this website](http://tomeko.net/online_tools/base64.php?lang=en)  to change pubkey from base64 to Hex. 
+Ok, now we can bond some coins to that pubkey:
+```
+basecli bond --stake=1steak --validator=<validator-pubkey-hex> --sequence=0 --chain-id=<chain-id> --name=test
+```
+Nice. We can see there are two validators:
+
+```
+basecli validatorset
+```
+Check the balance of $MYADDR2 to see the difference: it has 1 less `steak`!
+```
+basecli account $MYADDR2
+```
+To confirm for certain the new validator is active, check tendermint:
+```
+curl localhost:46657/validators
+```
+Finally, to relinquish all your power, unbond some coins. You should see your VotingPower reduce and your account balance increase.
+```
+basecli unbond  --sequence=# --chain-id=<chain-id> --name=test
+```
+

 Great, now that we've initialized the chains, we can start both nodes in the background:
-```
-gaiad start --home=$HOME/.gaiad1  &> gaia1.log &
-NODE1_PID=$!
-gaia start --home=$HOME/.gaiad2  &> gaia2.log &
-NODE2_PID=$!
-```
-Note we save the PID so we can later kill the processes. Of course, you can peak at your logs with tail gaia1.log, or follow them for a bit with tail -f gaia1.log.

+
+    gaiad start --home=$HOME/.gaiad1  &> gaia1.log &

+
+Note that we save the PID so we can later kill the processes. You can peak at your logs with ``tail gaia1.log``, or follow them for a bit with ``tail -f gaia1.log``.

 Nice. We can also lookup the validator set:

-```
-**Note** We need to be careful with the `chain-id` & `sequence`

 BREAKING CHANGES
 
@@ -17,6 +18,9 @@ BREAKING CHANGES
 * [store] Add `SubspaceIterator` and `ReverseSubspaceIterator` to `KVStore` interface
 * [basecoin] NewBasecoinApp takes a `dbm.DB` and uses namespaced DBs for substores
 * All module keepers now require a codespace, see basecoin or democoin for usage
+* Many changes to names throughout 
+  * Type as a prefix naming convention applied (ex. BondMsg -> MsgBond) 
+  * Removed redundancy in names (ex. stake.StakeKeeper -> stake.Keeper)
 
 BUG FIXES
 * Gaia now uses stake, ported from github.com/cosmos/gaia

 # IBC Specification
 
-IBC(Inter-Blockchain Communication) protocol is used by multiple zones on Cosmos. Using IBC, the zones can send coins or arbitrary data to other zones.
+The IBC (Inter Blockchain Communication) protocol specifies how tokens, 
+non-fungible assets and complex objects can be moved securely between different
+zones (independent blockchains). IBC is conceptually similar to TCP/IP in the 
+sense that anyone can implement it in order to be able to establish IBC
+connections with willing clients.

-How IBC module treats incoming IBC packets is simillar with how BaseApp treats incoming transactions. Therefore, the components of IBC module have their corresponding pair in BaseApp.

 Testnet Setup
 =============
 
+**Note:** THIS DOCUMENT IS OUT OF DATE
+
 See the `installation guide <../sdk/install.html>`__ for details on installation.
 
 Here is a quick example to get you off your feet:
 
-First, generate a new key with a name, and save the address:
+First, generate a couple of genesis transactions to be incorparated into the genesis file, this will create two keys with the password ``1234567890``
 
 ::
 
-    MYNAME=<your name>
-    gaiacli keys new $MYNAME
+    gaiad init gen-tx --name=foo --home=$HOME/.gaiad1
+    gaiad init gen-tx --name=bar --home=$HOME/.gaiad2
     gaiacli keys list
-    MYADDR=<your newly generated address>
 
-
-Now initialize a gaia chain:
+**Note:** If you've already run these tests you may need to overwrite keys using the ``--OWK`` flag
+When you list the keys you should see two addresses, we'll need these later so take note. 
+Now let's actually create the genesis files for both nodes:
 
 ::
 
-    gaiad init --home=$HOME/.gaiad1
-
-you should see seed phrase for genesis account in the output & config & data folder in the home directory.
-
-In the config folder, there will be the following files: ``config.toml``, ``genesis.json``, ``node_key.json``, and ``priv_validator.json``.
-
-The genesis file should look like this:
-
-::
-
-    {
-      "genesis_time": "0001-01-01T00:00:00Z",
-      "chain_id": "test-chain-0TRiTa",
-      "validators": [
-        {
-          "pub_key": {
-            "type": "AC26791624DE60",
-            "value": "<value>"
-          },
-          "power": 10,
-          "name": ""
-        }
-      ],
-      "app_hash": "",
-      "app_state": {
-        "accounts": [
-          {
-            "address": "<ADDR>",
-            "coins": [
-              {
-                "denom": "steak",
-                "amount": 9007199254740992
-              }
-            ]
-          }
-        ]
-      }
-    }
-
-**Note:** We need to change the denomination of token from default to ``steak`` in the genesis file.
-
-Then, recover the genesis account with ``gaiacli``:
-
-::
-
-    gaiacli keys add <name> --recover
-
-By now, you have set up the first node. This is great!
-
-We can add a second node on our local machine by initiating a node in a new directory, and copying in the ``genesis.json``:
-
-::
-
-    gaiad init --home=$HOME/.gaiad2
-
-and replace the ``genesis.json`` and ``config.toml`` files:
-
-::
-
-    cp $HOME/.gaiad/config/genesis.json $HOME/.gaiad2/config
-    cp $HOME/.gaiad/config/config.toml $HOME/.gaiad2/config
-
-then, get the node id of first node:
-
-::
-
-    gaiad show_node_id --home=$HOME/.gaiad1
-
-We need to also modify $HOME/.gaiad2/config.toml to set new seeds and ports. It should look like:
-
-::
-
-    proxy_app = "tcp://127.0.0.1:46668"
-    moniker = "anonymous"
-    fast_sync = true
-    db_backend = "leveldb"
-    log_level = "state:info,*:error"
-    
-    [rpc]
-    laddr = "tcp://0.0.0.0:46667"
-    
-    [p2p]
-    laddr = "tcp://0.0.0.0:46666"
-    persistent_peers = "<node1-ID>@0.0.0.0:46656"
+    cp -a ~/.gaiad2/config/gentx/. ~/.gaiad1/config/gentx/
+    cp -a ~/.gaiad1/config/gentx/. ~/.gaiad2/config/gentx/
+    gaiad init --gen-txs --home=$HOME/.gaiad1 --chain-id=test-chain
+    gaiad init --gen-txs --home=$HOME/.gaiad2 --chain-id=test-chain
 
+**Note:** If you've already run these tests you may need to overwrite genesis using the ``-o`` flag
+What we just did is copy the genesis transactions between each of the nodes so there is a common genesis transaction set; then we created both genesis files independantly from each home directory. Importantly both nodes have independantly created their ``genesis.json`` and ``config.toml`` files, which should be identical between nodes.

-FEATURES
-
-* Context now has access to the application-configured logger
+## 0.16.0 (TBD)
 
 BREAKING CHANGES
 
+* Move module REST/CLI packages to x/[module]/client/rest and x/[module]/client/cli
+* Gaia simple-staking bond and unbond functions replaced 
+* [stake] Delegator bonds now store the height at which they were updated
+* All module keepers now require a codespace, see basecoin or democoin for usage
+* Many changes to names throughout 
+  * Type as a prefix naming convention applied (ex. BondMsg -> MsgBond)

 ## 0.15.0 (April 29, 2018)
 
+NOTE: v0.15.0 is a large breaking change that updates the encoding scheme to use
+[Amino](github.com/tendermint/go-amino). 
+
+For details on how this changes encoding for public keys and addresses,
+see the [docs](https://github.com/tendermint/tendermint/blob/v0.19.1/docs/specification/new-spec/encoding.md#public-key-cryptography).
+
+BREAKING CHANGES
+
+* Remove go-wire, use go-amino
+* [store] Add `SubspaceIterator` and `ReverseSubspaceIterator` to `KVStore` interface
+* [basecoin] NewBasecoinApp takes a `dbm.DB` and uses namespaced DBs for substores
+
 FEATURES:
 
 * Add CacheContext
 * Add auto sequencing to client
 * Add FeeHandler to ante handler
-* Gaia stake commands include, DeclareCandidacy, EditCandidacy, Delegate, Unbond
-* MountStoreWithDB without providing a custom store works.
