-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!

 crypto is the cryptographic package adapted for Tendermint's uses

 ## Importing it
+To get the interfaces,
 `import "github.com/tendermint/tendermint/crypto"`

+For any specific algorithm, use its specific module e.g.
+`import "github.com/tendermint/tendermint/crypto/ed25519"`
+
+If you want to decode bytes into one of the types, but don't care about the specific algorithm, use
+`import "github.com/tendermint/tendermint/crypto/amino"`
+
 ## Binary encoding

 For Binary encoding, please refer to the [Tendermint encoding spec](https://github.com/tendermint/tendermint/blob/master/docs/spec/blockchain/encoding.md).
