-# Roadmap
-
-BREAKING CHANGES:
-- Better support for injecting randomness
-- Upgrade consensus for more real-time use of evidence
-
-FEATURES:
-- Use the chain as its own CA for nodes and validators
-- Tooling to run multiple blockchains/apps, possibly in a single process
-- State syncing (without transaction replay)
-- Add authentication and rate-limitting to the RPC
-
-IMPROVEMENTS:
-- Improve subtleties around mempool caching and logic
-- Consensus optimizations:
-	- cache block parts for faster agreement after round changes
-	- propagate block parts rarest first
-- Better testing of the consensus state machine (ie. use a DSL)
-- Auto compiled serialization/deserialization code instead of go-wire reflection
-
-BUG FIXES:
-- Graceful handling/recovery for apps that have non-determinism or fail to halt
-- Graceful handling/recovery for violations of safety, or liveness

-As part of our [Coordinated Vulnerability Disclosure
-Policy](https://tendermint.com/security), we operate a bug bounty.
-See the policy for more details on submissions and rewards.
-
-Here is a list of examples of the kinds of bugs we're most interested in:
-
-## Specification
-
-- Conceptual flaws
-- Ambiguities, inconsistencies, or incorrect statements
-- Mis-match between specification and implementation of any component
-
-## Consensus
-
-Assuming less than 1/3 of the voting power is Byzantine (malicious):
-
-- Validation of blockchain data structures, including blocks, block parts,
-  votes, and so on
-- Execution of blocks
-- Validator set changes
-- Proposer round robin
-- Two nodes committing conflicting blocks for the same height (safety failure)
-- A correct node signing conflicting votes
-- A node halting (liveness failure)
-- Syncing new and old nodes
-
-## Networking
-
-- Authenticated encryption (MITM, information leakage)
-- Eclipse attacks
-- Sybil attacks
-- Long-range attacks
-- Denial-of-Service
-
-## RPC
-
-- Write-access to anything besides sending transactions
-- Denial-of-Service
-- Leakage of secrets
-
-## Denial-of-Service
-
-Attacks may come through the P2P network or the RPC:
-
-- Amplification attacks
-- Resource abuse
-- Deadlocks and race conditions
-- Panics and unhandled errors
-
-## Libraries
-
-- Serialization (Amino)
-- Reading/Writing files and databases
-- Logging and monitoring
-
-## Cryptography
-
-- Elliptic curves for validator signatures
-- Hash algorithms and Merkle trees for block validation
-- Authenticated encryption for P2P connections
-
-## Light Client
-
-- Validation of blockchain data structures
-- Correctly validating an incorrect proof
-- Incorrectly validating a correct proof
-- Syncing validator set changes

+# The core consensus algorithm.
+
+* state.go - The state machine as detailed in the whitepaper
+* reactor.go - A reactor that connects the state machine to the gossip network
+
+# Go-routine summary
+
+The reactor runs 2 go-routines for each added peer: gossipDataRoutine and gossipVotesRoutine.
+
+The consensus state runs two persistent go-routines: timeoutRoutine and receiveRoutine.
+Go-routines are also started to trigger timeouts and to avoid blocking when the internalMsgQueue is really backed up.
+
+# Replay/WAL
+
+A write-ahead log is used to record all messages processed by the receiveRoutine,
+which amounts to all inputs to the consensus state machine:
+messages from peers, messages from ourselves, and timeouts.
+They can be played back deterministically at startup or using the replay console.

+localnode
+=========
+
+It is assumed that you have already `setup docker <https://docs.docker.com/engine/installation/>`__.
+
+Description
+-----------
+Image for local testnets.
+
+Add the tendermint binary to the image by attaching it in a folder to the `/tendermint` mount point.
+
+It assumes that the configuration was created by the `tendermint testnet` command and it is also attached to the `/tendermint` mount point.
+
+Example:
+This example builds a linux tendermint binary under the `build/` folder, creates tendermint configuration for a single-node validator and runs the node:
+```
+cd $GOPATH/src/github.com/tendermint/tendermint
+
+#Build binary
+make build-linux
+
+#Create configuration
+docker run -e LOG="stdout" -v `pwd`/build:/tendermint tendermint/localnode testnet --o . --v 1
+
+#Run the node
+docker run -v `pwd`/build:/tendermint tendermint/localnode
+```
+
+Logging
+-------
+Log is saved under the attached volume, in the `tendermint.log` file. If the `LOG` environment variable is set to `stdout` at start, the log is not saved, but printed on the screen.
+
+Special binaries
+----------------
+If you have multiple binaries with different names, you can specify which one to run with the BINARY environment variable. The path of the binary is relative to the attached volume.
+
+docker-compose.yml
+==================
+This file creates a 4-node network using the localnode image. The nodes of the network are exposed to the host machine on ports 46656-46657, 46659-46660, 46661-46662, 46663-46664 respectively.

 Application Architecture Guide
 ==============================
 
-Here we provide a brief guide on the recommended architecture of a Tendermint blockchain
+Overview
-application.
+--------
 
-The following diagram provides a superb example:
+A blockchain application is more than the consensus engine and the
+transaction logic (eg. smart contracts, business logic) as implemented
+in the ABCI app. There are also (mobile, web, desktop) clients that will
+need to connect and make use of the app. We will assume for now that you
+have a well designed transactions and database model, but maybe this
+will be the topic of another article. This article is more interested in
+various ways of setting up the "plumbing" and connecting these pieces,
+and demonstrating some evolving best practices.
 
-https://drive.google.com/open?id=1yR2XpRi9YCY9H9uMfcw8-RMJpvDyvjz9
+Security
+--------
 
-The end-user application here is the Cosmos Voyager, at the bottom left.
+A very important aspect when constructing a blockchain is security. The
-Voyager communicates with a REST API exposed by a local Light-Client Daemon.
+consensus model can be DoSed (no consensus possible) by corrupting 1/3
-The Light-Client Daemon is an application specific program that communicates with
+of the validators and exploited (writing arbitrary blocks) by corrupting
-Tendermint nodes and verifies Tendermint light-client proofs through the Tendermint Core RPC.
+2/3 of the validators. So, while the security is not that of the
-The Tendermint Core process communicates with a local ABCI application, where the
+"weakest link", you should take care that the "average link" is
-user query or transaction is actually processed.
+sufficiently hardened.
 
-The ABCI application must be a deterministic result of the Tendermint consensus - any external influence
+One big attack surface on the validators is the communication between
-on the application state that didn't come through Tendermint could cause a
+the ABCI app and the tendermint core. This should be highly protected.
-consensus failure. Thus *nothing* should communicate with the application except Tendermint via ABCI.
+Ideally, the app and the core are running on the same machine, so no
+external agent can target the communication channel. You can use unix
+sockets (with permissions preventing access from other users), or even
+compile the two apps into one binary if the ABCI app is also writen in
+go. If you are unable to do that due to language support, then the ABCI
+app should bind a TCP connection to localhost (127.0.0.1), which is less
+efficient and secure, but still not reachable from outside. If you must
+run the ABCI app and tendermint core on separate machines, make sure you
+have a secure communication channel (ssh tunnel?)
 
-If the application is written in Go, it can be compiled into the Tendermint binary.
+Now assuming, you have linked together your app and the core securely,
-Otherwise, it should use a unix socket to communicate with Tendermint.
+you must also make sure no one can get on the machine it is hosted on.
-If it's necessary to use TCP, extra care must be taken to encrypt and authenticate the connection.
+At this point it is basic network security. Run on a secure operating
+system (SELinux?). Limit who has access to the machine (user accounts,
+but also where the physical machine is hosted). Turn off all services
+except for ssh, which should only be accessible by some well-guarded
+public/private key pairs (no password). And maybe even firewall off
+access to the ports used by the validators, so only known validators can
+connect.
 
-All reads from the app happen through the Tendermint `/abci_query` endpoint.
+There was also a suggestion on slack from @jhon about compiling
-All writes to the app happen through the Tendermint `/broadcast_tx_*` endpoints.
+everything together with a unikernel for more security, such as
+`Mirage <https://mirage.io>`__ or
+`UNIK <https://github.com/emc-advanced-dev/unik>`__.
 
-The Light-Client Daemon is what provides light clients (end users) with nearly all the security of a full node.
+Connecting your client to the blockchain
-It formats and broadcasts transactions, and verifies proofs of queries and transaction results.
+----------------------------------------
-Note that it need not be a daemon - the Light-Client logic could instead be implemented in the same process as the end-user application.
 
-Note for those ABCI applications with weaker security requirements, the functionality of the Light-Client Daemon can be moved
+Tendermint Core RPC
-into the ABCI application process itself. That said, exposing the application process to anything besides Tendermint over ABCI
+~~~~~~~~~~~~~~~~~~~
-requires extreme caution, as all transactions, and possibly all queries, should still pass through Tendermint.
 
-See the following for more extensive documentation:
+The concept is that the ABCI app is completely hidden from the outside
-- [Interchain Standard for the Light-Client REST API](https://github.com/cosmos/cosmos-sdk/pull/1028)
+world and only communicated through a tested and secured `interface
-- [Tendermint RPC Docs](https://tendermint.github.io/slate/)
+exposed by the tendermint core <./specification/rpc.html>`__. This interface
-- [Tendermint in Production](https://github.com/tendermint/tendermint/pull/1618)
+exposes a lot of data on the block header and consensus process, which
-- [Tendermint Basics](https://tendermint.readthedocs.io/en/master/using-tendermint.html)
+is quite useful for externally verifying the system. It also includes
-- [ABCI spec](https://github.com/tendermint/abci/blob/master/specification.rst)
+3(!) methods to broadcast a transaction (propose it for the blockchain,
+and possibly await a response). And one method to query app-specific
+data from the ABCI application.
+
+Pros:
+* Server code already written
+* Access to block headers to validate merkle proofs (nice for light clients)
+* Basic read/write functionality is supported
+
+Cons:
+* Limited interface to app. All queries must be serialized into
+[]byte (less expressive than JSON over HTTP) and there is no way to push
+data from ABCI app to the client (eg. notify me if account X receives a
+transaction)
+
+Custom ABCI server
+~~~~~~~~~~~~~~~~~~
+
+This was proposed by @wolfposd on slack and demonstrated by
+`TMChat <https://github.com/wolfposd/TMChat>`__, a sample app. The
+concept is to write a custom server for your app (with typical REST
+API/websockets/etc for easy use by a mobile app). This custom server is
+in the same binary as the ABCI app and data store, so can easily react
+to complex events there that involve understanding the data format (send
+a message if my balance drops below 500). All "writes" sent to this
+server are proxied via websocket/JSON-RPC to tendermint core. When they
+come back as deliver\_tx over ABCI, they will be written to the data
+store. For "reads", we can do any queries we wish that are supported by
+our architecture, using any web technology that is useful. The general
+architecture is shown in the following diagram:
+
+Pros: \* Separates application logic from blockchain logic \* Allows
+much richer, more flexible client-facing API \* Allows pub-sub, watching
+certain fields, etc.
+
+Cons: \* Access to ABCI app can be dangerous (be VERY careful not to
+write unless it comes from the validator node) \* No direct access to
+the blockchain headers to verify tx \* You must write your own API (but
+maybe that's a pro...)
+
+Hybrid solutions
+~~~~~~~~~~~~~~~~
+
+Likely the least secure but most versatile. The client can access both
+the tendermint node for all blockchain info, as well as a custom app
+server, for complex queries and pub-sub on the abci app.
+
+Pros: All from both above solutions
+
+Cons: Even more complexity; even more attack vectors (less
+security)
+
+Scalability
+-----------
+
+Read replica using non-validating nodes? They could forward transactions
+to the validators (fewer connections, more security), and locally allow
+all queries in any of the above configurations. Thus, while
+transaction-processing speed is limited by the speed of the abci app and
+the number of validators, one should be able to scale our read
+performance to quite an extent (until the replication process drains too
+many resources from the validator nodes).

 After a few seconds, all the nodes should connect to each other and start
 making blocks! For more information, see the Tendermint Networks section
 of `the guide to using Tendermint <using-tendermint.html>`__.
 
-But wait! Steps 3 and 4 are quite manual. Instead, use `this script <https://github.com/tendermint/tendermint/blob/develop/docs/examples/init_testnet.sh>`__, which does the heavy lifting for you. And it gets better.
-
-Instead of the previously linked script to initialize the files required for a testnet, we have the ``tendermint testnet`` command. By default, running ``tendermint testnet`` will create all the required files, just like the script. Of course, you'll still need to manually edit some fields in the ``config.toml``. Alternatively, see the available flags to auto-populate the ``config.toml`` with the fields that would otherwise be passed in via flags when running ``tendermint node``. As you might imagine, this command is useful for manual or automated deployments.

 Automated Deployments
 ---------------------
 
-The easiest and fastest way to get a testnet up in less than 5 minutes.
+While the manual deployment is easy enough, an automated deployment is
+usually quicker. The below examples show different tools that can be used
+for automated deployments.
 
-Local
+Automated Deployment using Kubernetes
-^^^^^
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-With ``docker`` and ``docker-compose`` installed, run the command:
+The `mintnet-kubernetes tool <https://github.com/tendermint/tools/tree/master/mintnet-kubernetes>`__
+allows automating the deployment of a Tendermint network on an already
+provisioned Kubernetes cluster. For simple provisioning of a Kubernetes
+cluster, check out the `Google Cloud Platform <https://cloud.google.com/>`__.
+
+Automated Deployment using Terraform and Ansible
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The `terraform-digitalocean tool <https://github.com/tendermint/tools/tree/master/terraform-digitalocean>`__
+allows creating a set of servers on the DigitalOcean cloud.
+
+The `ansible playbooks <https://github.com/tendermint/tools/tree/master/ansible>`__
+allow creating and managing a ``basecoin`` or ``ethermint`` testnet on provisioned servers.
+
+Package Deployment on Linux for developers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``tendermint`` and ``basecoin`` applications can be installed from RPM or DEB packages on
+Linux machines for development purposes. The packages are configured to be validators on the
+one-node network that the machine represents. The services are not started after installation,
+this way giving an opportunity to reconfigure the applications before starting.
+
+The Ansible playbooks in the previous section use this repository to install ``basecoin``.
+After installation, additional steps are executed to make sure that the multi-node testnet has
+the right configuration before start.
+
+Install from the CentOS/RedHat repository:
 
 ::
 
-    make localnet-start
+    rpm --import https://tendermint-packages.interblock.io/centos/7/os/x86_64/RPM-GPG-KEY-Tendermint
+    wget -O /etc/yum.repos.d/tendermint.repo https://tendermint-packages.interblock.io/centos/7/os/x86_64/tendermint.repo
+    yum install basecoin
 
-from the root of the tendermint repository. This will spin up a 4-node local testnet.
