+
+Tendermint Core is Byzantine Fault Tolerant (BFT) middleware that takes a state transition machine, written in any programming language,
 and securely replicates it on many machines.
 
-For protocol details, see [the specification](/docs/spec).
+For more background, see the [introduction](https://tendermint.com/intro).
 
-## A Note on Production Readiness
+To get started developing applications, see the [application developers guide](https://tendermint.com/docs/guides/app-development).
 
-While Tendermint is being used in production in private, permissioned
-environments, we are still working actively to harden and audit it in preparation
-for use in public blockchains, such as the [Cosmos Network](https://cosmos.network/).
-We are also still making breaking changes to the protocol and the APIs.
-Thus we tag the releases as *alpha software*.
-
-In any case, if you intend to run Tendermint in production,
-please [contact us](https://riot.im/app/#/room/#tendermint:matrix.org) :)

-## Versioning
+## Resources
 
-### SemVer
+### Tendermint Core
 
-Tendermint uses [SemVer](http://semver.org/) to determine when and how the version changes.
-According to SemVer, anything in the public API can change at any time before version 1.0.0
+- [Introduction](https://tendermint.com/intro)
+- [Docs](https://tendermint.com/docs)
+- [Software using Tendermint](https://tendermint.com/ecosystem)
 
-To provide some stability to Tendermint users in these 0.X.X days, the MINOR version is used
-to signal breaking changes across a subset of the total public API. This subset includes all
-interfaces exposed to other processes (cli, rpc, p2p, etc.), but does not
-include the in-process Go APIs.
+### Sub-projects
 
-That said, breaking changes in the following packages will be documented in the
-CHANGELOG even if they don't lead to MINOR version bumps:
+* [ABCI](http://github.com/tendermint/abci), the Application Blockchain Interface
+* [Go-Wire](http://github.com/tendermint/go-wire), a deterministic serialization library
+* [Go-Crypto](http://github.com/tendermint/go-crypto), an elliptic curve cryptography library
+* [TmLibs](http://github.com/tendermint/tmlibs), an assortment of Go libraries
+* [Merkleeyes](http://github.com/tendermint/merkleeyes), a balanced, binary Merkle tree for ABCI apps
 
-- types
-- rpc/client
-- config
-- node
+### Tools
+* [Deployment, Benchmarking, and Monitoring](https://github.com/tendermint/tools)
 
-Exported objects in these packages that are not covered by the versioning scheme
-are explicitly marked by `// UNSTABLE` in their go doc comment and may change at any
-time without notice. Functions, types, and values in any other package may also change at any time.
+### Applications
 
-### Upgrades
+* [Ethermint](http://github.com/tendermint/ethermint): Ethereum on Tendermint
+* [Basecoin](http://github.com/tendermint/basecoin), a cryptocurrency application framework
 
-In an effort to avoid accumulating technical debt prior to 1.0.0,
-we do not guarantee that breaking changes (ie. bumps in the MINOR version)
-will work with existing tendermint blockchains. In these cases you will
-have to start a new blockchain, or write something custom to get the old
-data into the new chain.
+### More
 
-However, any bump in the PATCH version should be compatible with existing histories
-(if not please open an [issue](https://github.com/tendermint/tendermint/issues)).

-# 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)

-# Application BlockChain Interface (ABCI)
-
-[![CircleCI](https://circleci.com/gh/tendermint/abci.svg?style=svg)](https://circleci.com/gh/tendermint/abci)
-
-Blockchains are systems for multi-master state machine replication.
-**ABCI** is an interface that defines the boundary between the replication engine (the blockchain),
-and the state machine (the application).
-Using a socket protocol, a consensus engine running in one process
-can manage an application state running in another.
-
-Previously, the ABCI was referred to as TMSP.
-
-The community has provided a number of addtional implementations, see the [Tendermint Ecosystem](https://tendermint.com/ecosystem)
-
-## Specification
-
-A detailed description of the ABCI methods and message types is contained in:
-
-- [A prose specification](specification.md)
-- [A protobuf file](https://github.com/tendermint/abci/blob/master/types/types.proto)
-- [A Go interface](https://github.com/tendermint/abci/blob/master/types/application.go).
-
-For more background information on ABCI, motivations, and tendermint, please visit [the documentation](http://tendermint.readthedocs.io/en/master/).
-The two guides to focus on are the `Application Development Guide` and `Using ABCI-CLI`.
-
-
-## Protocl Buffers
-
-To compile the protobuf file, run:
-
-```
-make protoc
-```
-
-See `protoc --help` and [the Protocol Buffers site](https://developers.google.com/protocol-buffers)
-for details on compiling for other languages. Note we also include a [GRPC](http://www.grpc.io/docs)
-service definition.
-
-## Install ABCI-CLI
-
-The `abci-cli` is a simple tool for debugging ABCI servers and running some
-example apps. To install it:
-
-```
-go get github.com/tendermint/abci
-cd $GOPATH/src/github.com/tendermint/abci
-make get_vendor_deps
-make install
-```
-
-## Implementation
-
-We provide three implementations of the ABCI in Go:
-
-- Golang in-process
-- ABCI-socket
-- GRPC
-
-Note the GRPC version is maintained primarily to simplify onboarding and prototyping and is not receiving the same
-attention to security and performance as the others
-
-### In Process
-
-The simplest implementation just uses function calls within Go.
-This means ABCI applications written in Golang can be compiled with TendermintCore and run as a single binary.
-
-See the [examples](#examples) below for more information.
-
-### Socket (TSP)
-
-ABCI is best implemented as a streaming protocol.
-The socket implementation provides for asynchronous, ordered message passing over unix or tcp.
-Messages are serialized using Protobuf3 and length-prefixed with a [signed Varint](https://developers.google.com/protocol-buffers/docs/encoding?csw=1#signed-integers)
-
-For example, if the Protobuf3 encoded ABCI message is `0xDEADBEEF` (4 bytes), the length-prefixed message is `0x08DEADBEEF`, since `0x08` is the signed varint
-encoding of `4`. If the Protobuf3 encoded ABCI message is 65535 bytes long, the length-prefixed message would be like `0xFEFF07...`.
-
-Note the benefit of using this `varint` encoding over the old version (where integers were encoded as `<len of len><big endian len>` is that
-it is the standard way to encode integers in Protobuf. It is also generally shorter.
-
-### GRPC
-
-GRPC is an rpc framework native to Protocol Buffers with support in many languages.
-Implementing the ABCI using GRPC can allow for faster prototyping, but is expected to be much slower than
-the ordered, asynchronous socket protocol. The implementation has also not received as much testing or review.
-
-Note the length-prefixing used in the socket implementation does not apply for GRPC.
-
-## Usage
-
-The `abci-cli` tool wraps an ABCI client and can be used for probing/testing an ABCI server.
-For instance, `abci-cli test` will run a test sequence against a listening server running the Counter application (see below).
-It can also be used to run some example applications.
-See [the documentation](http://tendermint.readthedocs.io/en/master/) for more details.
-
-### Examples
-
-Check out the variety of example applications in the [example directory](example/).
-It also contains the code refered to by the `counter` and `kvstore` apps; these apps come
-built into the `abci-cli` binary.
-
-#### Counter
-
-The `abci-cli counter` application illustrates nonce checking in transactions. It's code looks like:
-
-```golang
-func cmdCounter(cmd *cobra.Command, args []string) error {
-
-	app := counter.NewCounterApplication(flagSerial)
-
-	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
-
-	// Start the listener
-	srv, err := server.NewServer(flagAddrC, flagAbci, app)
-	if err != nil {
-		return err
-	}
-	srv.SetLogger(logger.With("module", "abci-server"))
-	if err := srv.Start(); err != nil {
-		return err
-	}
-
-	// Wait forever
-	cmn.TrapSignal(func() {
-		// Cleanup
-		srv.Stop()
-	})
-	return nil
-}
-```
-
-and can be found in [this file](cmd/abci-cli/abci-cli.go).
-
-#### kvstore
-
-The `abci-cli kvstore` application, which illustrates a simple key-value Merkle tree
-
-```golang
-func cmdKVStore(cmd *cobra.Command, args []string) error {
-	logger := log.NewTMLogger(log.NewSyncWriter(os.Stdout))
-
-	// Create the application - in memory or persisted to disk
-	var app types.Application
-	if flagPersist == "" {
-		app = kvstore.NewKVStoreApplication()
-	} else {
-		app = kvstore.NewPersistentKVStoreApplication(flagPersist)
-		app.(*kvstore.PersistentKVStoreApplication).SetLogger(logger.With("module", "kvstore"))
-	}
-
-	// Start the listener
-	srv, err := server.NewServer(flagAddrD, flagAbci, app)
-	if err != nil {
-		return err
-	}
-	srv.SetLogger(logger.With("module", "abci-server"))
-	if err := srv.Start(); err != nil {
-		return err
-	}
-
-	// Wait forever
-	cmn.TrapSignal(func() {
-		// Cleanup
-		srv.Stop()
-	})
-	return nil

-# KVStore
-
-There are two app's here: the KVStoreApplication and the PersistentKVStoreApplication.
-
-## KVStoreApplication
-
-The KVStoreApplication is a simple merkle key-value store. 
-Transactions of the form `key=value` are stored as key-value pairs in the tree.
-Transactions without an `=` sign set the value to the key.
-The app has no replay protection (other than what the mempool provides).
-
-## PersistentKVStoreApplication
-
-The PersistentKVStoreApplication wraps the KVStoreApplication
-and provides two additional features:
-
-1) persistence of state across app restarts (using Tendermint's ABCI-Handshake mechanism)
-2) validator set changes
-
-The state is persisted in leveldb along with the last block committed,
-and the Handshake allows any necessary blocks to be replayed.
-Validator set changes are effected using the following transaction format:
-
-```
-val:pubkey1/power1,addr2/power2,addr3/power3"
-```
-
-where `power1` is the new voting power for the validator with `pubkey1` (possibly a new one).
-There is no sybil protection against new validators joining. 
-Validators can be removed by setting their power to `0`.

-ABCI Specification
-==================
-
-NOTE: this file has moved to `specification.md <./specification.md>`__. It is left to prevent link breakages for the forseable future. It can safely be deleted in a few months.
-
-Message Types
-~~~~~~~~~~~~~
-
-ABCI requests/responses are defined as simple Protobuf messages in `this
-schema
-file <https://github.com/tendermint/abci/blob/master/types/types.proto>`__.
-TendermintCore sends the requests, and the ABCI application sends the
-responses. Here, we provide an overview of the messages types and how they
-are used by Tendermint. Then we describe each request-response pair as a
-function with arguments and return values, and add some notes on usage.
-
-Some messages (``Echo, Info, InitChain, BeginBlock, EndBlock, Commit``), don't
-return errors because an error would indicate a critical failure in the
-application and there's nothing Tendermint can do.  The problem should be
-addressed and both Tendermint and the application restarted.  All other
-messages (``SetOption, Query, CheckTx, DeliverTx``) return an
-application-specific response ``Code uint32``, where only ``0`` is reserved for
-``OK``.
-
-Some messages (``SetOption, Query, CheckTx, DeliverTx``) return
-non-deterministic data in the form of ``Info`` and ``Log``. The ``Log`` is
-intended for the literal output from the application's logger, while the
-``Info`` is any additional info that should be returned.
-
-The first time a new blockchain is started, Tendermint calls ``InitChain``.
-From then on, the Block Execution Sequence that causes the committed state to
-be updated is as follows:
-
-``BeginBlock, [DeliverTx], EndBlock, Commit``
-
-where one ``DeliverTx`` is called for each transaction in the block.
-Cryptographic commitments to the results of DeliverTx, EndBlock, and
-Commit are included in the header of the next block.
-
-Tendermint opens three connections to the application to handle the different message
-types:
-
-- ``Consensus Connection - InitChain, BeginBlock, DeliverTx, EndBlock, Commit``
-
-- ``Mempool Connection - CheckTx``
-
-- ``Info Connection - Info, SetOption, Query``
-
-The ``Flush`` message is used on every connection, and the ``Echo`` message
-is only used for debugging.
-
-Note that messages may be sent concurrently across all connections -
-a typical application will thus maintain a distinct state for each
-connection. They may be referred to as the ``DeliverTx state``, the
-``CheckTx state``, and the ``Commit state`` respectively.
-
-See below for more details on the message types and how they are used.
-
-Echo
-^^^^
-
--  **Arguments**:
-
-   -  ``Message (string)``: A string to echo back
-
--  **Returns**:
-
-   -  ``Message (string)``: The input string
-
--  **Usage**:
-
-   -  Echo a string to test an abci client/server implementation
-
-Flush
-^^^^^
-
--  **Usage**:
-
-   -  Signals that messages queued on the client should be flushed to
-      the server. It is called periodically by the client implementation
-      to ensure asynchronous requests are actually sent, and is called
-      immediately to make a synchronous request, which returns when the
-      Flush response comes back.
-
-Info
-^^^^
-
--  **Arguments**:
-
-   -  ``Version (string)``: The Tendermint version
-
--  **Returns**:
-
-   -  ``Data (string)``: Some arbitrary information
-   -  ``Version (Version)``: Version information
-   -  ``LastBlockHeight (int64)``: Latest block for which the app has
-      called Commit
-   -  ``LastBlockAppHash ([]byte)``: Latest result of Commit
-
--  **Usage**:
-
-   - Return information about the application state.
-   - Used to sync Tendermint with the application during a handshake that
-     happens on startup.
-   - Tendermint expects ``LastBlockAppHash`` and ``LastBlockHeight`` to be
-     updated during ``Commit``, ensuring that ``Commit`` is never called twice
-     for the same block height.
-
-SetOption
-^^^^^^^^^
-
--  **Arguments**:
-
-   -  ``Key (string)``: Key to set
-   -  ``Value (string)``: Value to set for key
-
--  **Returns**:
-
-   -  ``Code (uint32)``: Response code
-   -  ``Log (string)``: The output of the application's logger. May be non-deterministic.
-   -  ``Info (string)``: Additional information. May be non-deterministic.
-
--  **Usage**:
-
-   - Set non-consensus critical application specific options.
-   - e.g. Key="min-fee", Value="100fermion" could set the minimum fee required for CheckTx
-     (but not DeliverTx - that would be consensus critical).
-
-InitChain
-^^^^^^^^^
-
--  **Arguments**:
-
-   -  ``Validators ([]Validator)``: Initial genesis validators
-   -  ``AppStateBytes ([]byte)``: Serialized initial application state
-
--  **Usage**:
-
-   - Called once upon genesis.
-
-Query
-^^^^^
-
--  **Arguments**:
-
-   -  ``Data ([]byte)``: Raw query bytes. Can be used with or in lieu of
-      Path.
-   -  ``Path (string)``: Path of request, like an HTTP GET path. Can be
-      used with or in liue of Data.
-   -  Apps MUST interpret '/store' as a query by key on the underlying
-      store. The key SHOULD be specified in the Data field.
-   -  Apps SHOULD allow queries over specific types like '/accounts/...'
-      or '/votes/...'
-   -  ``Height (int64)``: The block height for which you want the query
-      (default=0 returns data for the latest committed block). Note that
-      this is the height of the block containing the application's
-      Merkle root hash, which represents the state as it was after
-      committing the block at Height-1
-   -  ``Prove (bool)``: Return Merkle proof with response if possible
-
--  **Returns**:
-
-   -  ``Code (uint32)``: Response code.
-   -  ``Log (string)``: The output of the application's logger. May be non-deterministic.
-   -  ``Info (string)``: Additional information. May be non-deterministic.
-   -  ``Index (int64)``: The index of the key in the tree.
-   -  ``Key ([]byte)``: The key of the matching data.
-   -  ``Value ([]byte)``: The value of the matching data.
-   -  ``Proof ([]byte)``: Proof for the data, if requested.
-   -  ``Height (int64)``: The block height from which data was derived.
-      Note that this is the height of the block containing the
-      application's Merkle root hash, which represents the state as it
-      was after committing the block at Height-1
-
--  **Usage**:
-
-   - Query for data from the application at current or past height.
-   - Optionally return Merkle proof.
-
-BeginBlock
-^^^^^^^^^^
-
--  **Arguments**:
-
-   -  ``Hash ([]byte)``: The block's hash. This can be derived from the
-      block header.
-   -  ``Header (struct{})``: The block header
-   -  ``AbsentValidators ([]int32)``: List of indices of validators not
-      included in the LastCommit
-   -  ``ByzantineValidators ([]Evidence)``: List of evidence of
-      validators that acted maliciously
-
--  **Usage**:
-
-   - Signals the beginning of a new block. Called prior to any DeliverTxs.
-   - The header is expected to at least contain the Height.
-   - The ``AbsentValidators`` and ``ByzantineValidators`` can be used to
-     determine rewards and punishments for the validators.
-
-CheckTx
-^^^^^^^
-
--  **Arguments**:
-
-   -  ``Tx ([]byte)``: The request transaction bytes
-
--  **Returns**:
-
-   -  ``Code (uint32)``: Response code
-   -  ``Data ([]byte)``: Result bytes, if any.
-   -  ``Log (string)``: The output of the application's logger. May be non-deterministic.
-   -  ``Info (string)``: Additional information. May be non-deterministic.
-   -  ``GasWanted (int64)``: Amount of gas request for transaction.
-   -  ``GasUsed (int64)``: Amount of gas consumed by transaction.
-   -  ``Tags ([]cmn.KVPair)``: Key-Value tags for filtering and indexing transactions (eg. by account).
-   -  ``Fee (cmn.KI64Pair)``: Fee paid for the transaction.
-
--  **Usage**: Validate a mempool transaction, prior to broadcasting or
-   proposing. CheckTx should perform stateful but light-weight checks
-   of the validity of the transaction (like checking signatures and account balances),
-   but need not execute in full (like running a smart contract).
-
-   Tendermint runs CheckTx and DeliverTx concurrently with eachother,
-   though on distinct ABCI connections - the mempool connection and the consensus
-   connection, respectively.
-
-   The application should maintain a separate state to support CheckTx.
-   This state can be reset to the latest committed state during ``Commit``,
-   where Tendermint ensures the mempool is locked and not sending new ``CheckTx``.
-   After ``Commit``, the mempool will rerun CheckTx on all remaining
-   transactions, throwing out any that are no longer valid.
-
-   Keys and values in Tags must be UTF-8 encoded strings (e.g. "account.owner": "Bob", "balance": "100.0", "date": "2018-01-02")
-
-
-DeliverTx
-^^^^^^^^^
-
--  **Arguments**:
-
-   -  ``Tx ([]byte)``: The request transaction bytes.
-
--  **Returns**:
-
-   -  ``Code (uint32)``: Response code.
-   -  ``Data ([]byte)``: Result bytes, if any.
-   -  ``Log (string)``: The output of the application's logger. May be non-deterministic.
-   -  ``Info (string)``: Additional information. May be non-deterministic.
-   -  ``GasWanted (int64)``: Amount of gas requested for transaction.
-   -  ``GasUsed (int64)``: Amount of gas consumed by transaction.
-   -  ``Tags ([]cmn.KVPair)``: Key-Value tags for filtering and indexing transactions (eg. by account).
-   -  ``Fee (cmn.KI64Pair)``: Fee paid for the transaction.
-
--  **Usage**:
-
-   - Deliver a transaction to be executed in full by the application. If the transaction is valid,
-     returns CodeType.OK.
-   - Keys and values in Tags must be UTF-8 encoded strings (e.g. "account.owner": "Bob", "balance": "100.0", "time": "2018-01-02T12:30:00Z")
-
-EndBlock
-^^^^^^^^
-
--  **Arguments**:
-
-   -  ``Height (int64)``: Height of the block just executed.
-
--  **Returns**:
-
-   -  ``ValidatorUpdates ([]Validator)``: Changes to validator set (set
-      voting power to 0 to remove).
-   -  ``ConsensusParamUpdates (ConsensusParams)``: Changes to
-      consensus-critical time, size, and other parameters.
-
--  **Usage**:
-
-   - Signals the end of a block.
-   - Called prior to each Commit, after all transactions.
-   - Validator set and consensus params are updated with the result.
-   - Validator pubkeys are expected to be go-wire encoded.
-
-Commit
-^^^^^^
-
--  **Returns**:
-
-   -  ``Data ([]byte)``: The Merkle root hash
-
--  **Usage**:
-
-   - Persist the application state.
-   - Return a Merkle root hash of the application state.
-   - It's critical that all application instances return the same hash. If not,
-     they will not be able to agree on the next block, because the hash is
-     included in the next block!
