-
-## 0.20.0
-
-*June 6th, 2018*
-
-This is the first in a series of breaking releases coming to Tendermint after
-soliciting developer feedback and conducting security audits.
-
-This release does not break any blockchain data structures or
-protocols other than the ABCI messages between Tendermint and the application.

-
- - cmd: if there is no genesis, exit immediately instead of waiting around for one to show.
- - types: `Signer.Sign` returns an error.
- - state: every validator set change is persisted to disk, which required some changes to the `State` structure.
- - p2p: new `p2p.Peer` interface used for all reactor methods (instead of `*p2p.Peer` struct).
-
-FEATURES:
- - rpc: `/validators?height=X` allows querying of validators at previous heights.

-
-## 0.10.3 (August 10, 2017)

-  - new flag, `--consensus.create_empty_blocks`; when set to false, blocks are only created when there are txs or when the AppHash changes.
-  - new config option, `consensus.create_empty_blocks_interval`; an empty block is created after this many seconds.
-  - in normal operation, `create_empty_blocks = true` and `create_empty_blocks_interval = 0`, so blocks are being created all the time (as in all previous versions of tendermint). The number of empty blocks can be reduced by increasing `create_empty_blocks_interval` or by setting `create_empty_blocks = false`.
-  - new `TxsAvailable()` method added to Mempool that returns a channel which fires when txs are available.
-  - new heartbeat message added to consensus reactor to notify peers that a node is waiting for txs before entering propose step.
-- rpc: Add `syncing` field to response returned by `/status`. Is `true` while in fast-sync mode.

-
-IMPROVEMENTS:
-- Add a Code of Conduct
-- Variety of improvements as suggested by `megacheck` tool

-
-## 0.10.0 (June 2, 2017)
-
-Includes major updates to configuration, logging, and json serialization.
-Also includes the Grand Repo-Merge of 2017.
-
-BREAKING CHANGES:
-
-- Config and Flags:
-  - The `config` map is replaced with a [`Config` struct](https://github.com/tendermint/tendermint/blob/master/config/config.go#L11),
-containing substructs: `BaseConfig`, `P2PConfig`, `MempoolConfig`, `ConsensusConfig`, `RPCConfig`
-  - This affects the following flags:
-    - `--seeds` is now `--p2p.seeds`
-    - `--node_laddr` is now `--p2p.laddr`
-    - `--pex` is now `--p2p.pex`
-    - `--skip_upnp` is now `--p2p.skip_upnp`
-    - `--rpc_laddr` is now `--rpc.laddr`
-    - `--grpc_laddr` is now `--rpc.grpc_laddr`
-  - Any configuration option now within a substract must come under that heading in the `config.toml`, for instance:
-    ```
-    [p2p]
-    laddr="tcp://1.2.3.4:46656"
-
-    [consensus]
-    timeout_propose=1000
-    ```
-  - Use viper and `DefaultConfig() / TestConfig()` functions to handle defaults, and remove `config/tendermint` and `config/tendermint_test`
-  - Change some function and method signatures to
-  - Change some [function and method signatures](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) accomodate new config
-
-- Logger
-  - Replace static `log15` logger with a simple interface, and provide a new implementation using `go-kit`.
-See our new [logging library](https://github.com/tendermint/tmlibs/log) and [blog post](https://tendermint.com/blog/abstracting-the-logger-interface-in-go) for more details
-  - Levels `warn` and `notice` are removed (you may need to change them in your `config.toml`!)
-  - Change some [function and method signatures](https://gist.github.com/ebuchman/640d5fc6c2605f73497992fe107ebe0b) to accept a logger
-
-- JSON serialization:
-  - Replace `[TypeByte, Xxx]` with `{"type": "some-type", "data": Xxx}` in RPC and all `.json` files by using `go-wire/data`. For instance, a public key is now:
-    ```
-    "pub_key": {
-      "type": "ed25519",
-      "data": "83DDF8775937A4A12A2704269E2729FCFCD491B933C4B0A7FFE37FE41D7760D0"
-    }
-    ```
-  - Remove type information about RPC responses, so `[TypeByte, {"jsonrpc": "2.0", ... }]` is now just `{"jsonrpc": "2.0", ... }`
-  - Change `[]byte` to `data.Bytes` in all serialized types (for hex encoding)
-  - Lowercase the JSON tags in `ValidatorSet` fields
-  - Introduce `EventDataInner` for serializing events
-
-- Other:
-  - Send InitChain message in handshake if `appBlockHeight == 0`
-  - Do not include the `Accum` field when computing the validator hash. This makes the ValidatorSetHash unique for a given validator set, rather than changing with every block (as the Accum changes)
-  - Unsafe RPC calls are not enabled by default. This includes `/dial_seeds`, and all calls prefixed with `unsafe`. Use the `--rpc.unsafe` flag to enable.
-
-
-FEATURES:
-
-- Per-module log levels. For instance, the new default is `state:info,*:error`, which means the `state` package logs at `info` level, and everything else logs at `error` level
-- Log if a node is validator or not in every consensus round
-- Use ldflags to set git hash as part of the version
-- Ignore `address` and `pub_key` fields in `priv_validator.json` and overwrite them with the values derrived from the `priv_key`
-
-IMPROVEMENTS:
-
-- Merge `tendermint/go-p2p -> tendermint/tendermint/p2p` and `tendermint/go-rpc -> tendermint/tendermint/rpc/lib`
-- Update paths for grand repo merge:
-  - `go-common -> tmlibs/common`
-  - `go-data -> go-wire/data`
-  - All other `go-` libs, except `go-crypto` and `go-wire`, are merged under `tmlibs`
-- No global loggers (loggers are passed into constructors, or preferably set with a SetLogger method)
-- Return HTTP status codes with errors for RPC responses
-- Limit `/blockchain_info` call to return a maximum of 20 blocks
-- Use `.Wrap()` and `.Unwrap()` instead of eg. `PubKeyS` for `go-crypto` types
-- RPC JSON responses use pretty printing (via `json.MarshalIndent`)
-- Color code different instances of the consensus for tests
-- Isolate viper to `cmd/tendermint/commands` and do not read config from file for tests
-
-
-## 0.9.2 (April 26, 2017)
-
-BUG FIXES:
-
-- Fix bug in `ResetPrivValidator` where we were using the global config and log (causing external consumers, eg. basecoin, to fail).
-
-## 0.9.1 (April 21, 2017)
-
-FEATURES:
-
-- Transaction indexing - txs are indexed by their hash using a simple key-value store; easily extended to more advanced indexers
-- New `/tx?hash=X` endpoint to query for transactions and their DeliverTx result by hash. Optionally returns a proof of the tx's inclusion in the block
-- `tendermint testnet` command initializes files for a testnet
-
-IMPROVEMENTS:
-
-- CLI now uses Cobra framework
-- TMROOT is now TMHOME (TMROOT will stop working in 0.10.0)
-- `/broadcast_tx_XXX` also returns the Hash (can be used to query for the tx)
-- `/broadcast_tx_commit` also returns the height the block was committed in
-- ABCIResponses struct persisted to disk before calling Commit; makes handshake replay much cleaner
-- WAL uses #ENDHEIGHT instead of #HEIGHT (#HEIGHT will stop working in 0.10.0)
-- Peers included via `--seeds`, under `seeds` in the config, or in `/dial_seeds` are now persistent, and will be reconnected to if the connection breaks
-
-BUG FIXES:
-
-- Fix bug in fast-sync where we stop syncing after a peer is removed, even if they're re-added later
-- Fix handshake replay to handle validator set changes and results of DeliverTx when we crash after app.Commit but before state.Save()
-
-## 0.9.0 (March 6, 2017)
-
-BREAKING CHANGES:
-
-- Update ABCI to v0.4.0, where Query is now `Query(RequestQuery) ResponseQuery`, enabling precise proofs at particular heights:
-
-```
-message RequestQuery{
-	bytes data = 1;
-	string path = 2;
-	uint64 height = 3;
-	bool prove = 4;
-}
-
-message ResponseQuery{
-	CodeType          code        = 1;
-	int64             index       = 2;
-	bytes             key         = 3;
-	bytes             value       = 4;
-	bytes             proof       = 5;
-	uint64            height      = 6;
-	string            log         = 7;

-	Header  *Header `json:"header"`   // The block's Header
-}
-```
-

-	Hash        []byte        `json:"hash"`
-	PartsHeader PartSetHeader `json:"parts"`
-}
-```
-
-- `Vote` data type now includes validator address and index:

-## PreHistory
-
-Strict versioning only began with the release of v0.7.0, in late summer 2016.
-The project itself began in early summer 2014 and was workable decentralized cryptocurrency software by the end of that year.
-Through the course of 2015, in collaboration with Eris Industries (now Monax Indsutries),
-many additional features were integrated, including an implementation from scratch of the Ethereum Virtual Machine.
-That implementation now forms the heart of [Burrow](https://github.com/hyperledger/burrow).
-In the later half of 2015, the consensus algorithm was upgraded with a more asynchronous design and a more deterministic and robust implementation.
-
-By late 2015, frustration with the difficulty of forking a large monolithic stack to create alternative cryptocurrency designs led to the
-invention of the Application Blockchain Interface (ABCI), then called the Tendermint Socket Protocol (TMSP).
-The Ethereum Virtual Machine and various other transaction features were removed, and Tendermint was whittled down to a core consensus engine
-driving an application running in another process.
-The ABCI interface and implementation were iterated on and improved over the course of 2016,
-until versioned history kicked in with v0.7.0.

-# Conduct
-## Contact: adrian@tendermint.com
-
-* We are committed to providing a friendly, safe and welcoming environment for all, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, nationality, or other similar characteristic.
-
-* On Slack, please avoid using overtly sexual nicknames or other nicknames that might detract from a friendly, safe and welcoming environment for all.
-
-* Please be kind and courteous. There’s no need to be mean or rude.
-
-* Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
-
-* Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
-
-* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behaviour. We interpret the term “harassment” as including the definition in the [Citizen Code of Conduct](http://citizencodeofconduct.org/); if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don’t tolerate behavior that excludes people in socially marginalized groups.
-
-* Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact one of the channel admins or the person mentioned above immediately. Whether you’re a regular contributor or a newcomer, we care about making this community a safe place for you and we’ve got your back.

-# Moderation
-These are the policies for upholding our community’s standards of conduct. If you feel that a thread needs moderation, please contact the above mentioned person.
-
-1. Remarks that violate the Tendermint/COSMOS standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner.)
-
-2. Remarks that moderators find inappropriate, whether listed in the code of conduct or not, are also not allowed.
-
-3. Moderators will first respond to such remarks with a warning.
-
-4. If the warning is unheeded, the user will be “kicked,” i.e., kicked out of the communication channel to cool off.
-
-5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded.
-
-6. Moderators may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology.
-
-7. If a moderator bans someone and you think it was unjustified, please take it up with that moderator, or with a different moderator, in private. Complaints about bans in-channel are not allowed.
-
-8. Moderators are held to a higher standard than other community members. If a moderator creates an inappropriate situation, they should expect less leeway than others.
-
-In the Tendermint/COSMOS community we strive to go the extra step to look out for each other. Don’t just aim to be technically unimpeachable, try to be your best self. In particular, avoid flirting with offensive or sensitive issues, particularly if they’re off-topic; this all too often leads to unnecessary fights, hurt feelings, and damaged trust; worse, it can drive people away from the community entirely.
-
-And if someone takes issue with something you said or did, resist the urge to be defensive. Just stop doing what it was they complained about and apologize. Even if you feel you were misinterpreted or unfairly accused, chances are good there was something you could’ve communicated better — remember that it’s your responsibility to make your fellow Cosmonauts comfortable. Everyone wants to get along and we are all here first and foremost because we want to talk about cool technology. You will find that people will be eager to assume good intent and forgive as long as you earn their trust.
-
-The enforcement policies listed above apply to all official Tendermint/COSMOS venues.For other projects adopting the Tendermint/COSMOS Code of Conduct, please contact the maintainers of those projects for enforcement. If you wish to use this code of conduct for your own project, consider explicitly mentioning your moderation policy or making a copy with your own moderation policy so as to avoid confusion.

CONTRIBUTING.md

-# Contributing
-
-Thank you for considering making contributions to Tendermint and related repositories! Start by taking a look at the [coding repo](https://github.com/tendermint/coding) for overall information on repository workflow and standards.
-
-Please follow standard github best practices: fork the repo, branch from the tip of develop, make some commits, and submit a pull request to develop. See the [open issues](https://github.com/tendermint/tendermint/issues) for things we need help with!
-
-Please make sure to use `gofmt` before every commit - the easiest way to do this is have your editor run it for you upon saving a file.
-
-## Forking
-
-Please note that Go requires code to live under absolute paths, which complicates forking.
-While my fork lives at `https://github.com/ebuchman/tendermint`,
-the code should never exist at  `$GOPATH/src/github.com/ebuchman/tendermint`.
-Instead, we use `git remote` to add the fork as a new remote for the original repo,
-`$GOPATH/src/github.com/tendermint/tendermint `, and do all the work there.
-
-For instance, to create a fork and work on a branch of it, I would:
-
-  * Create the fork on github, using the fork button.
-  * Go to the original repo checked out locally (ie. `$GOPATH/src/github.com/tendermint/tendermint`)
-  * `git remote rename origin upstream`
-  * `git remote add origin git@github.com:ebuchman/basecoin.git`
-
-Now `origin` refers to my fork and `upstream` refers to the tendermint version.
-So I can `git push -u origin master` to update my fork, and make pull requests to tendermint from there.
-Of course, replace `ebuchman` with your git handle.
-
-To pull in updates from the origin repo, run
-
-    * `git fetch upstream`
-    * `git rebase upstream/master` (or whatever branch you want)
-
-Please don't make Pull Requests to `master`.
-
-## Dependencies
-
-We use [dep](https://github.com/golang/dep) to manage dependencies.
-
-That said, the master branch of every Tendermint repository should just build
-with `go get`, which means they should be kept up-to-date with their
-dependencies so we can get away with telling people they can just `go get` our
-software.
-
-Since some dependencies are not under our control, a third party may break our
-build, in which case we can fall back on `dep ensure` (or `make
-get_vendor_deps`). Even for dependencies under our control, dep helps us to
-keep multiple repos in sync as they evolve. Anything with an executable, such
-as apps, tools, and the core, should use dep.
-
-Run `dep status` to get a list of vendored dependencies that may not be
-up-to-date.
-
-## Vagrant
-
-If you are a [Vagrant](https://www.vagrantup.com/) user, you can get started
-hacking Tendermint with the commands below.
-
-NOTE: In case you installed Vagrant in 2017, you might need to run
-`vagrant box update` to upgrade to the latest `ubuntu/xenial64`.
-
-```
-vagrant up
-vagrant ssh
-make test
-```
-
-## Testing
-
-All repos should be hooked up to [CircleCI](https://circleci.com/).
-
-If they have `.go` files in the root directory, they will be automatically
-tested by circle using `go test -v -race ./...`. If not, they will need a
-`circle.yml`. Ideally, every repo has a `Makefile` that defines `make test` and
-includes its continuous integration status using a badge in the `README.md`.
-
-## Branching Model and Release
-
-User-facing repos should adhere to the branching model: http://nvie.com/posts/a-successful-git-branching-model/.
-That is, these repos should be well versioned, and any merge to master requires a version bump and tagged release.
-
-Libraries need not follow the model strictly, but would be wise to,
-especially `go-p2p` and `go-rpc`, as their versions are referenced in tendermint core.
-
-### Development Procedure:
-- the latest state of development is on `develop`
-- `develop` must never fail `make test`
-- no --force onto `develop` (except when reverting a broken commit, which should seldom happen)
-- create a development branch either on github.com/tendermint/tendermint, or your fork (using `git add origin`)
-- before submitting a pull request, begin `git rebase` on top of `develop`
-
-### Pull Merge Procedure:
-- ensure pull branch is rebased on develop
-- run `make test` to ensure that all tests pass
-- merge pull request
-- the `unstable` branch may be used to aggregate pull merges before testing once
-- push master may request that pull requests be rebased on top of `unstable`
-
-### Release Procedure:
-- start on `develop`
-- run integration tests (see `test_integrations` in Makefile)
-- prepare changelog/release issue
-- bump versions
-- push to release-vX.X.X to run the extended integration tests on the CI
-- merge to master
-- merge master back to develop
-
-### Hotfix Procedure:
-- start on `master`
-- checkout a new branch named hotfix-vX.X.X
-- make the required changes
-  - these changes should be small and an absolute necessity
-  - add a note to CHANGELOG.md
-- bumb versions
-- push to hotfix-vX.X.X to run the extended integration tests on the CI
-- merge hotfix-vX.X.X to master
-- merge hotfix-vX.X.X to develop
-- delete the hotfix-vX.X.X branch

-## Tendermint
-
-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 more background, see the [introduction](https://tendermint.readthedocs.io/en/master/introduction.html).
-
-To get started developing applications, see the [application developers guide](https://tendermint.readthedocs.io/en/master/getting-started.html).
-
-## How to use this image
-
-### Start one instance of the Tendermint core with the `kvstore` app
-
-A quick example of a built-in app and Tendermint core in one container.
-
-```
-docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint init
-docker run -it --rm -v "/tmp:/tendermint" tendermint/tendermint node --proxy_app=kvstore
-```
-
-## Local cluster
-
-To run a 4-node network, see the `Makefile` in the root of [the repo](https://github.com/tendermint/tendermint/master/Makefile) and run:
-
-```
-make build-linux
-make build-docker-localnode
-make localnet-start
-```
-
-Note that this will build and use a different image than the ones provided here.

-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications

-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-
-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).
-
-## A Note on Production Readiness
-
-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) :)
-
-## Security
-
-To report a security vulnerability, see our [bug bounty
-program](https://tendermint.com/security).
-
-For examples of the kinds of bugs we're looking for, see [SECURITY.md](SECURITY.md)
-

-## Contributing

-
-## Versioning
-
-### SemVer
-
-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
-
-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.
-
-That said, breaking changes in the following packages will be documented in the
-CHANGELOG even if they don't lead to MINOR version bumps:
-
-- types
-- rpc/client
-- config
-- node

-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.
-Functions, types, and values in any other package may also change at any time.
-
-### Upgrades
-
-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.
-
-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

-# Security
-
-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

-# Using ABCI-CLI
-
-To facilitate testing and debugging of ABCI servers and simple apps, we
-built a CLI, the `abci-cli`, for sending ABCI messages from the command
-line.
-
-## Install
-
-Make sure you [have Go installed](https://golang.org/doc/install).
-
-Next, install the `abci-cli` tool and example applications:
-
-    go get -u github.com/tendermint/abci/cmd/abci-cli
-
-If this fails, you may need to use [dep](https://github.com/golang/dep)
-to get vendored dependencies:
-
-    cd $GOPATH/src/github.com/tendermint/abci
-    make get_tools
-    make get_vendor_deps
-    make install
-
-Now run `abci-cli` to see the list of commands:
-
-    Usage:
-      abci-cli [command]
-
-    Available Commands:
-      batch       Run a batch of abci commands against an application
-      check_tx    Validate a tx
-      commit      Commit the application state and return the Merkle root hash
-      console     Start an interactive abci console for multiple commands
-      counter     ABCI demo example
-      deliver_tx  Deliver a new tx to the application
-      kvstore       ABCI demo example
-      echo        Have the application echo a message
-      help        Help about any command
-      info        Get some info about the application
-      query       Query the application state
-      set_option  Set an options on the application
-
-    Flags:
-          --abci string      socket or grpc (default "socket")
-          --address string   address of application socket (default "tcp://127.0.0.1:26658")
-      -h, --help             help for abci-cli
-      -v, --verbose          print the command and results as if it were a console session
-
-    Use "abci-cli [command] --help" for more information about a command.
-
-## KVStore - First Example
-
-The `abci-cli` tool lets us send ABCI messages to our application, to
-help build and debug them.
-
-The most important messages are `deliver_tx`, `check_tx`, and `commit`,
-but there are others for convenience, configuration, and information
-purposes.
-
-We'll start a kvstore application, which was installed at the same time
-as `abci-cli` above. The kvstore just stores transactions in a merkle
-tree.
-
-Its code can be found
-[here](https://github.com/tendermint/abci/blob/master/cmd/abci-cli/abci-cli.go)
-and looks like:
-
-    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
-    }
-
-Start by running:
-
-    abci-cli kvstore
-
-And in another terminal, run
-
-    abci-cli echo hello
-    abci-cli info
-
-You'll see something like:
-
-    -> data: hello
-    -> data.hex: 68656C6C6F
-
-and:
-
-    -> data: {"size":0}
-    -> data.hex: 7B2273697A65223A307D
-
-An ABCI application must provide two things:
-
--   a socket server
--   a handler for ABCI messages
-
-When we run the `abci-cli` tool we open a new connection to the
-application's socket server, send the given ABCI message, and wait for a
-response.
-
-The server may be generic for a particular language, and we provide a
-[reference implementation in
-Golang](https://github.com/tendermint/abci/tree/master/server). See the
-[list of other ABCI implementations](./ecosystem.html) for servers in
-other languages.
-
-The handler is specific to the application, and may be arbitrary, so
-long as it is deterministic and conforms to the ABCI interface
-specification.
-
-So when we run `abci-cli info`, we open a new connection to the ABCI
-server, which calls the `Info()` method on the application, which tells
-us the number of transactions in our Merkle tree.
-
-Now, since every command opens a new connection, we provide the
-`abci-cli console` and `abci-cli batch` commands, to allow multiple ABCI
-messages to be sent over a single connection.
-
-Running `abci-cli console` should drop you in an interactive console for
-speaking ABCI messages to your application.
-
-Try running these commands:
-
-    > echo hello
-    -> code: OK
-    -> data: hello
-    -> data.hex: 0x68656C6C6F
-
-    > info
-    -> code: OK
-    -> data: {"size":0}
-    -> data.hex: 0x7B2273697A65223A307D
-
-    > commit
-    -> code: OK
-    -> data.hex: 0x0000000000000000
-
-    > deliver_tx "abc"
-    -> code: OK
-
-    > info
-    -> code: OK
-    -> data: {"size":1}
-    -> data.hex: 0x7B2273697A65223A317D
-
-    > commit
-    -> code: OK
-    -> data.hex: 0x0200000000000000
-
-    > query "abc"
-    -> code: OK
-    -> log: exists
-    -> height: 0
-    -> value: abc
-    -> value.hex: 616263
-
-    > deliver_tx "def=xyz"
-    -> code: OK
-
-    > commit
-    -> code: OK
-    -> data.hex: 0x0400000000000000
-
-    > query "def"
-    -> code: OK
-    -> log: exists
-    -> height: 0
-    -> value: xyz
-    -> value.hex: 78797A
-
-Note that if we do `deliver_tx "abc"` it will store `(abc, abc)`, but if
-we do `deliver_tx "abc=efg"` it will store `(abc, efg)`.
-
-Similarly, you could put the commands in a file and run
-`abci-cli --verbose batch < myfile`.
-
-## Counter - Another Example
-
-Now that we've got the hang of it, let's try another application, the
-"counter" app.
-
-Like the kvstore app, its code can be found
-[here](https://github.com/tendermint/abci/blob/master/cmd/abci-cli/abci-cli.go)
-and looks like:
-
-    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
-    }
-
-The counter app doesn't use a Merkle tree, it just counts how many times
-we've sent a transaction, asked for a hash, or committed the state. The
-result of `commit` is just the number of transactions sent.
-
-This application has two modes: `serial=off` and `serial=on`.
-
-When `serial=on`, transactions must be a big-endian encoded incrementing
-integer, starting at 0.
-
-If `serial=off`, there are no restrictions on transactions.
-
-We can toggle the value of `serial` using the `set_option` ABCI message.
-
-When `serial=on`, some transactions are invalid. In a live blockchain,
-transactions collect in memory before they are committed into blocks. To
-avoid wasting resources on invalid transactions, ABCI provides the
-`check_tx` message, which application developers can use to accept or
-reject transactions, before they are stored in memory or gossipped to
-other peers.
-
-In this instance of the counter app, `check_tx` only allows transactions
-whose integer is greater than the last committed one.
-
-Let's kill the console and the kvstore application, and start the
-counter app:
-
-    abci-cli counter
-
-In another window, start the `abci-cli console`:
-
-    > set_option serial on
-    -> code: OK
-    -> log: OK (SetOption doesn't return anything.)
-
-    > check_tx 0x00
-    -> code: OK
-
-    > check_tx 0xff
-    -> code: OK
-
-    > deliver_tx 0x00
-    -> code: OK
-
-    > check_tx 0x00
-    -> code: BadNonce
-    -> log: Invalid nonce. Expected >= 1, got 0
-
-    > deliver_tx 0x01
-    -> code: OK
-
-    > deliver_tx 0x04
-    -> code: BadNonce
-    -> log: Invalid nonce. Expected 2, got 4
-
-    > info
-    -> code: OK
-    -> data: {"hashes":0,"txs":2}
-    -> data.hex: 0x7B22686173686573223A302C22747873223A327D
-
-This is a very simple application, but between `counter` and `kvstore`,
-its easy to see how you can build out arbitrary application states on
-top of the ABCI. [Hyperledger's
-Burrow](https://github.com/hyperledger/burrow) also runs atop ABCI,
-bringing with it Ethereum-like accounts, the Ethereum virtual-machine,
-Monax's permissioning scheme, and native contracts extensions.
-
-But the ultimate flexibility comes from being able to write the
-application easily in any language.
-
-We have implemented the counter in a number of languages [see the
-example directory](https://github.com/tendermint/abci/tree/master/example).
-
-To run the Node JS version, `cd` to `example/js` and run
-
-    node app.js
-
-(you'll have to kill the other counter application process). In another
-window, run the console and those previous ABCI commands. You should get
-the same results as for the Go version.
-
-## Bounties
-
-Want to write the counter app in your favorite language?! We'd be happy
-to add you to our [ecosystem](https://tendermint.com/ecosystem)! We're
-also offering [bounties](https://hackerone.com/tendermint/) for
-implementations in new languages!
-
-The `abci-cli` is designed strictly for testing and debugging. In a real
-deployment, the role of sending messages is taken by Tendermint, which
-connects to the app using three separate connections, each with its own
-pattern of messages.

-# Application Architecture Guide
-
-Here we provide a brief guide on the recommended architecture of a
-Tendermint blockchain application.
-
-The following diagram provides a superb example:
-
-<https://drive.google.com/open?id=1yR2XpRi9YCY9H9uMfcw8-RMJpvDyvjz9>
-
-The end-user application here is the Cosmos Voyager, at the bottom left.
-Voyager communicates with a REST API exposed by a local Light-Client
-Daemon. The Light-Client Daemon is an application specific program that
-communicates with Tendermint nodes and verifies Tendermint light-client
-proofs through the Tendermint Core RPC. The Tendermint Core process
-communicates with a local ABCI application, where the user query or
-transaction is actually processed.
-
-The ABCI application must be a deterministic result of the Tendermint
-consensus - any external influence on the application state that didn't
-come through Tendermint could cause a consensus failure. Thus *nothing*
-should communicate with the application except Tendermint via ABCI.
-
-If the application is written in Go, it can be compiled into the
-Tendermint binary. Otherwise, it should use a unix socket to communicate
-with Tendermint. If it's necessary to use TCP, extra care must be taken
-to encrypt and authenticate the connection.
-
-All reads from the app happen through the Tendermint `/abci_query`
-endpoint. All writes to the app happen through the Tendermint
-`/broadcast_tx_*` endpoints.
-
-The Light-Client Daemon is what provides light clients (end users) with
-nearly all the security of a full node. 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 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.
-

-# Application Development Guide
-
-## ABCI Design
-
-The purpose of ABCI is to provide a clean interface between state
-transition machines on one computer and the mechanics of their
-replication across multiple computers. The former we call 'application
-logic' and the latter the 'consensus engine'. Application logic
-validates transactions and optionally executes transactions against some
-persistent state. A consensus engine ensures all transactions are
-replicated in the same order on every machine. We call each machine in a
-consensus engine a 'validator', and each validator runs the same
-transactions through the same application logic. In particular, we are
-interested in blockchain-style consensus engines, where transactions are
-committed in hash-linked blocks.
-
-The ABCI design has a few distinct components:
-
--   message protocol
-    -   pairs of request and response messages
-    -   consensus makes requests, application responds
-    -   defined using protobuf
--   server/client
-    -   consensus engine runs the client
-    -   application runs the server
-    -   two implementations:
-        -   async raw bytes
-        -   grpc
--   blockchain protocol
-    -   abci is connection oriented
-    -   Tendermint Core maintains three connections:
-        -   [mempool connection](#mempool-connection): for checking if
-            transactions should be relayed before they are committed;
-            only uses `CheckTx`
-        -   [consensus connection](#consensus-connection): for executing
-            transactions that have been committed. Message sequence is
-            -for every block
-            -`BeginBlock, [DeliverTx, ...], EndBlock, Commit`
-        -   [query connection](#query-connection): for querying the
-            application state; only uses Query and Info
-
-The mempool and consensus logic act as clients, and each maintains an
-open ABCI connection with the application, which hosts an ABCI server.
-Shown are the request and response types sent on each connection.
-
-## Message Protocol
-
-The message protocol consists of pairs of requests and responses. Some
-messages have no fields, while others may include byte-arrays, strings,
-or integers. See the `message Request` and `message Response`
-definitions in [the protobuf definition
-file](https://github.com/tendermint/abci/blob/master/types/types.proto),
-and the [protobuf
-documentation](https://developers.google.com/protocol-buffers/docs/overview)
-for more details.
-
-For each request, a server should respond with the corresponding
-response, where order of requests is preserved in the order of
-responses.
-
-## Server
-
-To use ABCI in your programming language of choice, there must be a ABCI
-server in that language. Tendermint supports two kinds of implementation
-of the server:
-
--   Asynchronous, raw socket server (Tendermint Socket Protocol, also
-    known as TSP or Teaspoon)
--   GRPC
-
-Both can be tested using the `abci-cli` by setting the `--abci` flag
-appropriately (ie. to `socket` or `grpc`).
-
-See examples, in various stages of maintenance, in
-[Go](https://github.com/tendermint/abci/tree/master/server),
-[JavaScript](https://github.com/tendermint/js-abci),
-[Python](https://github.com/tendermint/abci/tree/master/example/python3/abci),
-[C++](https://github.com/mdyring/cpp-tmsp), and
-[Java](https://github.com/jTendermint/jabci).
-
-### GRPC
-
-If GRPC is available in your language, this is the easiest approach,
-though it will have significant performance overhead.
-
-To get started with GRPC, copy in the [protobuf
-file](https://github.com/tendermint/abci/blob/master/types/types.proto)
-and compile it using the GRPC plugin for your language. For instance,
-for golang, the command is `protoc --go_out=plugins=grpc:. types.proto`.
-See the [grpc documentation for more details](http://www.grpc.io/docs/).
-`protoc` will autogenerate all the necessary code for ABCI client and
-server in your language, including whatever interface your application
-must satisfy to be used by the ABCI server for handling requests.
-
-### TSP
-
-If GRPC is not available in your language, or you require higher
-performance, or otherwise enjoy programming, you may implement your own
-ABCI server using the Tendermint Socket Protocol, known affectionately
-as Teaspoon. The first step is still to auto-generate the relevant data
-types and codec in your language using `protoc`. Messages coming over
-the socket are Protobuf3 encoded, but additionally length-prefixed to
-facilitate use as a streaming protocol. Protobuf3 doesn't have an
-official length-prefix standard, so we use our own. The first byte in
-the prefix represents the length of the Big Endian encoded length. The
-remaining bytes in the prefix are the Big Endian encoded length.
-
-For example, if the Protobuf3 encoded ABCI message is 0xDEADBEEF (4
-bytes), the length-prefixed message is 0x0104DEADBEEF. If the Protobuf3
-encoded ABCI message is 65535 bytes long, the length-prefixed message
-would be like 0x02FFFF....
-
-Note this prefixing does not apply for grpc.
-
-An ABCI server must also be able to support multiple connections, as
-Tendermint uses three connections.
-
-## Client
-
-There are currently two use-cases for an ABCI client. One is a testing
-tool, as in the `abci-cli`, which allows ABCI requests to be sent via
-command line. The other is a consensus engine, such as Tendermint Core,
-which makes requests to the application every time a new transaction is
-received or a block is committed.
-
-It is unlikely that you will need to implement a client. For details of
-our client, see
-[here](https://github.com/tendermint/abci/tree/master/client).
-
-Most of the examples below are from [kvstore
-application](https://github.com/tendermint/abci/blob/master/example/kvstore/kvstore.go),
-which is a part of the abci repo. [persistent_kvstore
-application](https://github.com/tendermint/abci/blob/master/example/kvstore/persistent_kvstore.go)
-is used to show `BeginBlock`, `EndBlock` and `InitChain` example
-implementations.
-
-## Blockchain Protocol
-
-In ABCI, a transaction is simply an arbitrary length byte-array. It is
-the application's responsibility to define the transaction codec as they
-please, and to use it for both CheckTx and DeliverTx.
-
-Note that there are two distinct means for running transactions,
-corresponding to stages of 'awareness' of the transaction in the
-network. The first stage is when a transaction is received by a
-validator from a client into the so-called mempool or transaction pool
--this is where we use CheckTx. The second is when the transaction is
-successfully committed on more than 2/3 of validators - where we use
-DeliverTx. In the former case, it may not be necessary to run all the
-state transitions associated with the transaction, as the transaction
-may not ultimately be committed until some much later time, when the
-result of its execution will be different. For instance, an Ethereum
-ABCI app would check signatures and amounts in CheckTx, but would not
-actually execute any contract code until the DeliverTx, so as to avoid
-executing state transitions that have not been finalized.
-
-To formalize the distinction further, two explicit ABCI connections are
-made between Tendermint Core and the application: the mempool connection
-and the consensus connection. We also make a third connection, the query
-connection, to query the local state of the app.
-
-### Mempool Connection
-
-The mempool connection is used *only* for CheckTx requests. Transactions
-are run using CheckTx in the same order they were received by the
-validator. If the CheckTx returns `OK`, the transaction is kept in
-memory and relayed to other peers in the same order it was received.
-Otherwise, it is discarded.
-
-CheckTx requests run concurrently with block processing; so they should
-run against a copy of the main application state which is reset after
-every block. This copy is necessary to track transitions made by a
-sequence of CheckTx requests before they are included in a block. When a
-block is committed, the application must ensure to reset the mempool
-state to the latest committed state. Tendermint Core will then filter
-through all transactions in the mempool, removing any that were included
-in the block, and re-run the rest using CheckTx against the post-Commit
-mempool state (this behaviour can be turned off with
-`[mempool] recheck = false`).
-
-In go:
-
-    func (app *KVStoreApplication) CheckTx(tx []byte) types.Result {
-      return types.OK
-    }
-
-In Java:
-
-    ResponseCheckTx requestCheckTx(RequestCheckTx req) {
-        byte[] transaction = req.getTx().toByteArray();
-    
-        // validate transaction
-    
-        if (notValid) {
-            return ResponseCheckTx.newBuilder().setCode(CodeType.BadNonce).setLog("invalid tx").build();
-        } else {
-            return ResponseCheckTx.newBuilder().setCode(CodeType.OK).build();
-        }
-    }
-
-### Replay Protection
-
-To prevent old transactions from being replayed, CheckTx must implement
-replay protection.
-
-Tendermint provides the first defence layer by keeping a lightweight
-in-memory cache of 100k (`[mempool] cache_size`) last transactions in
-the mempool. If Tendermint is just started or the clients sent more than
-100k transactions, old transactions may be sent to the application. So
-it is important CheckTx implements some logic to handle them.
-
-There are cases where a transaction will (or may) become valid in some
-future state, in which case you probably want to disable Tendermint's
-cache. You can do that by setting `[mempool] cache_size = 0` in the
-config.
-
-### Consensus Connection
-
-The consensus connection is used only when a new block is committed, and
-communicates all information from the block in a series of requests:
-`BeginBlock, [DeliverTx, ...], EndBlock, Commit`. That is, when a block
-is committed in the consensus, we send a list of DeliverTx requests (one
-for each transaction) sandwiched by BeginBlock and EndBlock requests,
-and followed by a Commit.
-
-### DeliverTx
-
-DeliverTx is the workhorse of the blockchain. Tendermint sends the
-DeliverTx requests asynchronously but in order, and relies on the
-underlying socket protocol (ie. TCP) to ensure they are received by the
-app in order. They have already been ordered in the global consensus by
-the Tendermint protocol.
-
-DeliverTx returns a abci.Result, which includes a Code, Data, and Log.
-The code may be non-zero (non-OK), meaning the corresponding transaction
-should have been rejected by the mempool, but may have been included in
-a block by a Byzantine proposer.
-
-The block header will be updated (TODO) to include some commitment to
-the results of DeliverTx, be it a bitarray of non-OK transactions, or a
-merkle root of the data returned by the DeliverTx requests, or both.
-
-In go:
-
-    // tx is either "key=value" or just arbitrary bytes
-    func (app *KVStoreApplication) DeliverTx(tx []byte) types.Result {
-      parts := strings.Split(string(tx), "=")
-      if len(parts) == 2 {
-        app.state.Set([]byte(parts[0]), []byte(parts[1]))
-      } else {
-        app.state.Set(tx, tx)
-      }
-      return types.OK
-    }
-
-In Java:
-
-    /**
-     * Using Protobuf types from the protoc compiler, we always start with a byte[]
-     */
-    ResponseDeliverTx deliverTx(RequestDeliverTx request) {
-        byte[] transaction  = request.getTx().toByteArray();
-    
-        // validate your transaction
-    
-        if (notValid) {
-            return ResponseDeliverTx.newBuilder().setCode(CodeType.BadNonce).setLog("transaction was invalid").build();
-        } else {
-            ResponseDeliverTx.newBuilder().setCode(CodeType.OK).build();
-        }
-    
-    }
-
-### Commit
-
-Once all processing of the block is complete, Tendermint sends the
-Commit request and blocks waiting for a response. While the mempool may
-run concurrently with block processing (the BeginBlock, DeliverTxs, and
-EndBlock), it is locked for the Commit request so that its state can be
-safely reset during Commit. This means the app *MUST NOT* do any
-blocking communication with the mempool (ie. broadcast\_tx) during
-Commit, or there will be deadlock. Note also that all remaining
-transactions in the mempool are replayed on the mempool connection
-(CheckTx) following a commit.
-
-The app should respond to the Commit request with a byte array, which is
-the deterministic state root of the application. It is included in the
-header of the next block. It can be used to provide easily verified
-Merkle-proofs of the state of the application.
-
-It is expected that the app will persist state to disk on Commit. The
-option to have all transactions replayed from some previous block is the
-job of the [Handshake](#handshake).
-
-In go:
-
-    func (app *KVStoreApplication) Commit() types.Result {
-      hash := app.state.Hash()
-      return types.NewResultOK(hash, "")
-    }
-
-In Java:
-
-    ResponseCommit requestCommit(RequestCommit requestCommit) {
-    
-        // update the internal app-state
-        byte[] newAppState = calculateAppState();
-    
-        // and return it to the node
-        return ResponseCommit.newBuilder().setCode(CodeType.OK).setData(ByteString.copyFrom(newAppState)).build();
-    }
-
-### BeginBlock
-
-The BeginBlock request can be used to run some code at the beginning of
-every block. It also allows Tendermint to send the current block hash
-and header to the application, before it sends any of the transactions.
-
-The app should remember the latest height and header (ie. from which it
-has run a successful Commit) so that it can tell Tendermint where to
-pick up from when it restarts. See information on the Handshake, below.
-
-In go:
-
-    // Track the block hash and header information
-    func (app *PersistentKVStoreApplication) BeginBlock(params types.RequestBeginBlock) {
-      // update latest block info
-      app.blockHeader = params.Header
-    
-      // reset valset changes
-      app.changes = make([]*types.Validator, 0)
-    }
-
-In Java:
-
-    /*
-     * all types come from protobuf definition
-     */
-    ResponseBeginBlock requestBeginBlock(RequestBeginBlock req) {
-    
-        Header header = req.getHeader();
-        byte[] prevAppHash = header.getAppHash().toByteArray();
-        long prevHeight = header.getHeight();
-        long numTxs = header.getNumTxs();
-    
-        // run your pre-block logic. Maybe prepare a state snapshot, message components, etc
-    
-        return ResponseBeginBlock.newBuilder().build();
-    }
-
-### EndBlock
-
-The EndBlock request can be used to run some code at the end of every
-block. Additionally, the response may contain a list of validators,
-which can be used to update the validator set. To add a new validator or
-update an existing one, simply include them in the list returned in the
-EndBlock response. To remove one, include it in the list with a `power`
-equal to `0`. Tendermint core will take care of updating the validator
-set. Note the change in voting power must be strictly less than 1/3 per
-block if you want a light client to be able to prove the transition
-externally. See the [light client
-docs](https://godoc.org/github.com/tendermint/tendermint/lite#hdr-How_We_Track_Validators)
-for details on how it tracks validators.
-
-In go:
-
-    // Update the validator set
-    func (app *PersistentKVStoreApplication) EndBlock(req types.RequestEndBlock) types.ResponseEndBlock {
-      return types.ResponseEndBlock{ValidatorUpdates: app.ValUpdates}
-    }
-
-In Java:
-
-    /*
-     * Assume that one validator changes. The new validator has a power of 10
-     */
-    ResponseEndBlock requestEndBlock(RequestEndBlock req) {
-        final long currentHeight = req.getHeight();
-        final byte[] validatorPubKey = getValPubKey();
-    
-        ResponseEndBlock.Builder builder = ResponseEndBlock.newBuilder();
-        builder.addDiffs(1, Types.Validator.newBuilder().setPower(10L).setPubKey(ByteString.copyFrom(validatorPubKey)).build());
-    
-        return builder.build();
-    }
-
-### Query Connection
-
-This connection is used to query the application without engaging
-consensus. It's exposed over the tendermint core rpc, so clients can
-query the app without exposing a server on the app itself, but they must
-serialize each query as a single byte array. Additionally, certain
-"standardized" queries may be used to inform local decisions, for
-instance about which peers to connect to.
-
-Tendermint Core currently uses the Query connection to filter peers upon
-connecting, according to IP address or public key. For instance,
-returning non-OK ABCI response to either of the following queries will
-cause Tendermint to not connect to the corresponding peer:
-
--   `p2p/filter/addr/<addr>`, where `<addr>` is an IP address.
--   `p2p/filter/pubkey/<pubkey>`, where `<pubkey>` is the hex-encoded
-    ED25519 key of the node (not it's validator key)
-
-Note: these query formats are subject to change!
-
-In go:
-
-    func (app *KVStoreApplication) Query(reqQuery types.RequestQuery) (resQuery types.ResponseQuery) {
-      if reqQuery.Prove {
-        value, proof, exists := app.state.Proof(reqQuery.Data)
-        resQuery.Index = -1 // TODO make Proof return index
-        resQuery.Key = reqQuery.Data
-        resQuery.Value = value
-        resQuery.Proof = proof
-        if exists {
-          resQuery.Log = "exists"
-        } else {
-          resQuery.Log = "does not exist"
-        }
-        return
-      } else {
-        index, value, exists := app.state.Get(reqQuery.Data)
-        resQuery.Index = int64(index)
-        resQuery.Value = value
-        if exists {
-          resQuery.Log = "exists"
-        } else {
-          resQuery.Log = "does not exist"
-        }
-        return
-      }
-    }
-
-In Java:
-
-    ResponseQuery requestQuery(RequestQuery req) {
-        final boolean isProveQuery = req.getProve();
-        final ResponseQuery.Builder responseBuilder = ResponseQuery.newBuilder();
-    
-        if (isProveQuery) {
-            com.app.example.ProofResult proofResult = generateProof(req.getData().toByteArray());
-            final byte[] proofAsByteArray = proofResult.getAsByteArray();
-    
-            responseBuilder.setProof(ByteString.copyFrom(proofAsByteArray));
-            responseBuilder.setKey(req.getData());
-            responseBuilder.setValue(ByteString.copyFrom(proofResult.getData()));
-            responseBuilder.setLog(result.getLogValue());
-        } else {
-            byte[] queryData = req.getData().toByteArray();
-    
-            final com.app.example.QueryResult result = generateQueryResult(queryData);
-    
-            responseBuilder.setIndex(result.getIndex());
-            responseBuilder.setValue(ByteString.copyFrom(result.getValue()));
-            responseBuilder.setLog(result.getLogValue());
-        }
-    
-        return responseBuilder.build();
-    }
-
-### Handshake
-
-When the app or tendermint restarts, they need to sync to a common
-height. When an ABCI connection is first established, Tendermint will
-call `Info` on the Query connection. The response should contain the
-LastBlockHeight and LastBlockAppHash - the former is the last block for
-which the app ran Commit successfully, the latter is the response from
-that Commit.
-
-Using this information, Tendermint will determine what needs to be
-replayed, if anything, against the app, to ensure both Tendermint and
-the app are synced to the latest block height.
-
-If the app returns a LastBlockHeight of 0, Tendermint will just replay
-all blocks.
-
-In go:
-
-    func (app *KVStoreApplication) Info(req types.RequestInfo) (resInfo types.ResponseInfo) {
-      return types.ResponseInfo{Data: cmn.Fmt("{\"size\":%v}", app.state.Size())}
-    }
-
-In Java:
-
-    ResponseInfo requestInfo(RequestInfo req) {
-        final byte[] lastAppHash = getLastAppHash();
-        final long lastHeight = getLastHeight();
-        return ResponseInfo.newBuilder().setLastBlockAppHash(ByteString.copyFrom(lastAppHash)).setLastBlockHeight(lastHeight).build();
-    }
-
-### Genesis
-
-`InitChain` will be called once upon the genesis. `params` includes the
-initial validator set. Later on, it may be extended to take parts of the
-consensus params.
-
-In go:
-
-    // Save the validators in the merkle tree
-    func (app *PersistentKVStoreApplication) InitChain(params types.RequestInitChain) {
-      for _, v := range params.Validators {
-        r := app.updateValidator(v)
-        if r.IsErr() {
-          app.logger.Error("Error updating validators", "r", r)
-        }
-      }
-    }
-
-In Java:
-
-    /*
-     * all types come from protobuf definition
-     */
-    ResponseInitChain requestInitChain(RequestInitChain req) {
-        final int validatorsCount = req.getValidatorsCount();
-        final List<Types.Validator> validatorsList = req.getValidatorsList();
-    
-        validatorsList.forEach((validator) -> {
-            long power = validator.getPower();
-            byte[] validatorPubKey = validator.getPubKey().toByteArray();
-    
-            // do somehing for validator setup in app
-        });
-    
-        return ResponseInitChain.newBuilder().build();
-    }

-# Architecture Decision Records
-
-This is a location to record all high-level architecture decisions in the tendermint project.  Not the implementation details, but the reasoning that happened.  This should be refered to for guidance of the "right way" to extend the application.  And if we notice that the original decisions were lacking, we should have another open discussion, record the new decisions here, and then modify the code to match.

-# ADR 1: Logging
-
-## Context
-
-Current logging system in Tendermint is very static and not flexible enough.
-
-Issues: [358](https://github.com/tendermint/tendermint/issues/358), [375](https://github.com/tendermint/tendermint/issues/375).
-
-What we want from the new system:
-
-- per package dynamic log levels
-- dynamic logger setting (logger tied to the processing struct)
-- conventions
-- be more visually appealing
-
-"dynamic" here means the ability to set smth in runtime.
-
-## Decision
-
-### 1) An interface
-
-First, we will need an interface for all of our libraries (`tmlibs`, Tendermint, etc.). My personal preference is go-kit `Logger` interface (see Appendix A.), but that is too much a bigger change. Plus we will still need levels.
-
-```go
-# log.go
-type Logger interface {
-    Debug(msg string, keyvals ...interface{}) error
-    Info(msg string, keyvals ...interface{}) error
-    Error(msg string, keyvals ...interface{}) error
-
-	  With(keyvals ...interface{}) Logger
-}
-```
-
-On a side note: difference between `Info` and `Notice` is subtle. We probably
-could do without `Notice`. Don't think we need `Panic` or `Fatal` as a part of
-the interface. These funcs could be implemented as helpers. In fact, we already
-have some in `tmlibs/common`.
-
-- `Debug` - extended output for devs
-- `Info` - all that is useful for a user
-- `Error` - errors
-
-`Notice` should become `Info`, `Warn` either `Error` or `Debug` depending on the message, `Crit` -> `Error`.
-
-This interface should go into `tmlibs/log`. All libraries which are part of the core (tendermint/tendermint) should obey it.
-
-### 2) Logger with our current formatting
-
-On top of this interface, we will need to implement a stdout logger, which will be used when Tendermint is configured to output logs to STDOUT.
-
-Many people say that they like the current output, so let's stick with it.
-
-```
-NOTE[04-25|14:45:08] ABCI Replay Blocks                       module=consensus appHeight=0 storeHeight=0 stateHeight=0
-```
-
-Couple of minor changes:
-
-```
-I[04-25|14:45:08.322] ABCI Replay Blocks            module=consensus appHeight=0 storeHeight=0 stateHeight=0
-```
-
-Notice the level is encoded using only one char plus milliseconds.
-
-Note: there are many other formats out there like [logfmt](https://brandur.org/logfmt).
-
-This logger could be implemented using any logger - [logrus](https://github.com/sirupsen/logrus), [go-kit/log](https://github.com/go-kit/kit/tree/master/log), [zap](https://github.com/uber-go/zap), log15 so far as it
-
-a) supports coloring output<br>
-b) is moderately fast (buffering) <br>
-c) conforms to the new interface or adapter could be written for it <br>
-d) is somewhat configurable<br>
-
-go-kit is my favorite so far. Check out how easy it is to color errors in red https://github.com/go-kit/kit/blob/master/log/term/example_test.go#L12. Although, coloring could only be applied to the whole string :(
-
-```
-go-kit +: flexible, modular
-go-kit “-”: logfmt format https://brandur.org/logfmt
-
-logrus +: popular, feature rich (hooks), API and output is more like what we want
-logrus -: not so flexible
-```
-
-```go
-# tm_logger.go
-// NewTmLogger returns a logger that encodes keyvals to the Writer in
-// tm format.
-func NewTmLogger(w io.Writer) Logger {
-  return &tmLogger{kitlog.NewLogfmtLogger(w)}
-}
-
-func (l tmLogger) SetLevel(level string() {
-  switch (level) {
-    case "debug":
-      l.sourceLogger = level.NewFilter(l.sourceLogger, level.AllowDebug())
-  }
-}
-
-func (l tmLogger) Info(msg string, keyvals ...interface{}) error {
-  l.sourceLogger.Log("msg", msg, keyvals...)
-}
-
-# log.go
-func With(logger Logger, keyvals ...interface{}) Logger {
-  kitlog.With(logger.sourceLogger, keyvals...)
-}
-```
-
-Usage:
-
-```go
-logger := log.NewTmLogger(os.Stdout)
-logger.SetLevel(config.GetString("log_level"))
-node.SetLogger(log.With(logger, "node", Name))
-```
-
-**Other log formatters**
-
-In the future, we may want other formatters like JSONFormatter.
-
-```
-{ "level": "notice", "time": "2017-04-25 14:45:08.562471297 -0400 EDT", "module": "consensus", "msg": "ABCI Replay Blocks", "appHeight": 0, "storeHeight": 0, "stateHeight": 0 }
-```
-
-### 3) Dynamic logger setting
-
-https://dave.cheney.net/2017/01/23/the-package-level-logger-anti-pattern
-
-This is the hardest part and where the most work will be done. logger should be tied to the processing struct, or the context if it adds some fields to the logger.
-
-```go
-type BaseService struct {
-    log     log15.Logger
-    name    string
-    started uint32 // atomic
-    stopped uint32 // atomic
-...
-}
-```
-
-BaseService already contains `log` field, so most of the structs embedding it should be fine. We should rename it to `logger`.
-
-The only thing missing is the ability to set logger:
-
-```
-func (bs *BaseService) SetLogger(l log.Logger) {
-  bs.logger = l
-}
-```
-
-### 4) Conventions
-
-Important keyvals should go first. Example:
-
-```
-correct
-I[04-25|14:45:08.322] ABCI Replay Blocks                       module=consensus instance=1 appHeight=0 storeHeight=0 stateHeight=0
-```
-
-not
-
-```
-wrong
-I[04-25|14:45:08.322] ABCI Replay Blocks                       module=consensus appHeight=0 storeHeight=0 stateHeight=0 instance=1
-```
-
-for that in most cases you'll need to add `instance` field to a logger upon creating, not when u log a particular message:
-
-```go
-colorFn := func(keyvals ...interface{}) term.FgBgColor {
-		for i := 1; i < len(keyvals); i += 2 {
-			if keyvals[i] == "instance" && keyvals[i+1] == "1" {
-				return term.FgBgColor{Fg: term.Blue}
-			} else if keyvals[i] == "instance" && keyvals[i+1] == "1" {
-				return term.FgBgColor{Fg: term.Red}
-			}
-		}
-		return term.FgBgColor{}
-	}
-logger := term.NewLogger(os.Stdout, log.NewTmLogger, colorFn)
-
-c1 := NewConsensusReactor(...)
-c1.SetLogger(log.With(logger, "instance", 1))
-
-c2 := NewConsensusReactor(...)
-c2.SetLogger(log.With(logger, "instance", 2))
-```
-
-## Status
-
-proposed
-
-## Consequences
-
-### Positive
-
-Dynamic logger, which could be turned off for some modules at runtime. Public interface for other projects using Tendermint libraries.
-
-### Negative
-
-We may loose the ability to color keys in keyvalue pairs. go-kit allow you to easily change foreground / background colors of the whole string, but not its parts.
-
-### Neutral
-
-## Appendix A.
-
-I really like a minimalistic approach go-kit took with his logger https://github.com/go-kit/kit/tree/master/log:
-
-```
-type Logger interface {
-    Log(keyvals ...interface{}) error
-}
-```
-
-See [The Hunt for a Logger Interface](https://go-talks.appspot.com/github.com/ChrisHines/talks/structured-logging/structured-logging.slide). The advantage is greater composability (check out how go-kit defines colored logging or log-leveled logging on top of this interface https://github.com/go-kit/kit/tree/master/log).

-# ADR 2: Event Subscription
-
-## Context
-
-In the light client (or any other client), the user may want to **subscribe to
-a subset of transactions** (rather than all of them) using `/subscribe?event=X`. For
-example, I want to subscribe for all transactions associated with a particular
-account. Same for fetching. The user may want to **fetch transactions based on
-some filter** (rather than fetching all the blocks). For example, I want to get
-all transactions for a particular account in the last two weeks (`tx's block
-time >= '2017-06-05'`).
-
-Now you can't even subscribe to "all txs" in Tendermint.
-
-The goal is a simple and easy to use API for doing that.
-
-![Tx Send Flow Diagram](img/tags1.png)
-
-## Decision
-
-ABCI app return tags with a `DeliverTx` response inside the `data` field (_for
-now, later we may create a separate field_). Tags is a list of key-value pairs,
-protobuf encoded.
-
-Example data:
-
-```json
-{
-  "abci.account.name": "Igor",
-  "abci.account.address": "0xdeadbeef",
-  "tx.gas": 7
-}
-```
-
-### Subscribing for transactions events
-
-If the user wants to receive only a subset of transactions, ABCI-app must
-return a list of tags with a `DeliverTx` response. These tags will be parsed and
-matched with the current queries (subscribers). If the query matches the tags,
-subscriber will get the transaction event.
-
-```
-/subscribe?query="tm.event = Tx AND tx.hash = AB0023433CF0334223212243BDD AND abci.account.invoice.number = 22"
-```
-
-A new package must be developed to replace the current `events` package. It
-will allow clients to subscribe to a different types of events in the future:
-
-```
-/subscribe?query="abci.account.invoice.number = 22"
-/subscribe?query="abci.account.invoice.owner CONTAINS Igor"
-```
-
-### Fetching transactions
-
-This is a bit tricky because a) we want to support a number of indexers, all of
-which have a different API b) we don't know whenever tags will be sufficient
-for the most apps (I guess we'll see).
-
-```
-/txs/search?query="tx.hash = AB0023433CF0334223212243BDD AND abci.account.owner CONTAINS Igor"
-/txs/search?query="abci.account.owner = Igor"
-```
-
-For historic queries we will need a indexing storage (Postgres, SQLite, ...).
