-# Solana AccountsDb Plugin Interface
-
-This crate enables an AccountsDb plugin to be plugged into the Solana Validator runtime to take actions
-at the time of each account update; for example, saving the account state to an external database. The plugin must implement the `AccountsDbPlugin` trait. Please see the detail of the `accountsdb_plugin_interface.rs` for the interface definition.
-
-The plugin should produce a `cdylib` dynamic library, which must expose a `C` function `_create_plugin()` that
-instantiates the implementation of the interface.
-
-The `solana-accountsdb-plugin-postgres` crate provides an example of how to create a plugin which saves the accounts data into an
-external PostgreSQL databases.
-
-More information about Solana is available in the [Solana documentation](https://docs.solana.com/).

+## Overview
+
+An exchange is a marketplace where one asset can be traded for another.  This
+demo demonstrates one way to host an exchange on the Solana blockchain by
+emulating a currency exchange.
+
+The assets are virtual tokens held by investors who may post order requests to
+the exchange.  A Matcher monitors the exchange and posts swap requests for
+matching orders.  All the transactions can execute concurrently.
+
+## Premise
+
+- Exchange
+  -  An exchange is a marketplace where one asset can be traded for another.
+     The exchange in this demo is the on-chain program that implements the
+     tokens and the policies for trading those tokens.
+- Token
+  - A virtual asset that can be owned, traded, and holds virtual intrinsic value
+    compared to other assets.  There are four types of tokens in this demo, A,
+    B, C, D.  Each one may be traded for another.
+- Token account
+  - An account owned by the exchange that holds a quantity of one type of token.
+- Account request
+  - A request to create a token account
+- Token request
+  - A request to deposit tokens of a particular type into a token account.
+- Asset pair
+  - A struct with fields Base and Quote, representing the two assets which make up a 
+    trading pair,  which themselves are Tokens. The Base or 'primary' asset is the
+    numerator and the Quote is the denominator for pricing purposes.
+- Order side
+  - Describes which side of the market an investor wants to place a trade on. Options
+    are "Bid" or "Ask", where a bid represents an offer to purchase the Base asset of
+    the AssetPair for a sum of the Quote Asset and an Ask is an offer to sell Base asset
+    for the Quote asset.
+- Price ratio
+  -  An expression of the relative prices of two tokens. Calculated with the Base
+     Asset as the numerator and the Quote Asset as the denominator. Ratios are 
+     represented as fixed point numbers.  The fixed point scaler is defined in
+     [exchange_state.rs](https://github.com/solana-labs/solana/blob/c2fdd1362a029dcf89c8907c562d2079d977df11/programs/exchange_api/src/exchange_state.rs#L7)
+- Order request
+  - A Solana transaction sent by a trader to the exchange to submit an order. 
+    Order requests are made up of the token pair, the order side (bid or ask),
+    quantity of the primary token, the price ratio, and the two token accounts
+    to be credited/deducted.  An example trade request looks like "T AB 5 2" 
+    which reads "Exchange 5 A tokens to B tokens at a price ratio of 1:2"  A fulfilled trade would result in 5 A tokens
+    deducted and 10 B tokens credited to the trade initiator's token accounts.
+    Successful order requests result in an order.
+- Order
+  - The result of a successful order request.  orders are stored in
+    accounts owned by the submitter of the order request.  They can only be
+    canceled by their owner but can be used by anyone in a trade swap.  They
+    contain the same information as the order request.
+- Price spread
+  - The difference between the two matching orders. The spread is the
+    profit of the Matcher initiating the swap request.
+- Match requirements
+  - Policies that result in a successful trade swap.
+- Match request
+  - A request to fill two complementary orders (bid/ask), resulting if successful,
+    in a trade being created.
+- Trade
+  - A successful trade is created from two matching orders that meet
+    swap requirements which are submitted in a Match Request by a Matcher and
+    executed by the exchange. A trade may not wholly satisfy one or both of the
+    orders in which case the orders are adjusted appropriately. Upon execution,
+    tokens are distributed to the traders' accounts and any overlap or 
+    "negative spread" between orders is deposited into the Matcher's profit
+    account.  All successful trades are recorded in the data of a new solana 
+    account for posterity.
+- Investor
+  - Individual investors who hold a number of tokens and wish to trade them on
+    the exchange.  Investors operate as Solana thin clients who own a set of
+    accounts containing tokens and/or order requests.  Investors post
+    transactions to the exchange in order to request tokens and post or cancel
+    order requests.
+- Matcher
+  - An agent who facilitates trading between investors.  Matchers operate as
+    Solana thin clients who monitor all the orders looking for a trade
+    match.  Once found, the Matcher issues a swap request to the exchange.
+    Matchers are the engine of the exchange and are rewarded for their efforts by
+    accumulating the price spreads of the swaps they initiate.  Matchers also
+    provide current bid/ask price and OHLCV (Open, High, Low, Close, Volume)
+    information on demand via a public network port.
+- Transaction fees
+  - Solana transaction fees are paid for by the transaction submitters who are
+    the Investors and Matchers.
+
+## Exchange startup
+
+The exchange is up and running when it reaches a state where it can take
+investors' trades and Matchers' match requests.  To achieve this state the
+following must occur in order:
+
+- Start the Solana blockchain
+- Start the  thin-client
+- The Matcher subscribes to change notifications for all the accounts owned by
+  the exchange program id.  The subscription is managed via Solana's JSON RPC
+  interface.
+- The Matcher starts responding to queries for bid/ask price and OHLCV
+
+The Matcher responding successfully to price and OHLCV requests is the signal to
+the investors that trades submitted after that point will be analyzed.  <!--This
+is not ideal, and instead investors should be able to submit trades at any time,
+and the Matcher could come and go without missing a trade.  One way to achieve
+this is for the Matcher to read the current state of all accounts looking for all
+open orders.-->
+
+Investors will initially query the exchange to discover their current balance
+for each type of token.  If the investor does not already have an account for
+each type of token, they will submit account requests.  Matcher as well will
+request accounts to hold the tokens they earn by initiating trade swaps.
+
+```rust
+/// Supported token types
+pub enum Token {
+    A,
+    B,
+    C,
+    D,
+}
+
+/// Supported token pairs
+pub enum TokenPair {
+    AB,
+    AC,
+    AD,
+    BC,
+    BD,
+    CD,
+}
+
+pub enum ExchangeInstruction {
+    /// New token account
+    /// key 0 - Signer
+    /// key 1 - New token account
+    AccountRequest,
+}
+
+/// Token accounts are populated with this structure
+pub struct TokenAccountInfo {
+    /// Investor who owns this account
+    pub owner: Pubkey,
+    /// Current number of tokens this account holds
+    pub tokens: Tokens,
+}
+```
+
+For this demo investors or Matcher can request more tokens from the exchange at
+any time by submitting token requests. In non-demos, an exchange of this type
+would provide another way to exchange a 3rd party asset into tokens.
+
+To request tokens, investors submit transfer requests:
+
+```rust
+pub enum ExchangeInstruction {
+    /// Transfer tokens between two accounts
+    /// key 0 - Account to transfer tokens to
+    /// key 1 - Account to transfer tokens from.  This can be the exchange program itself,
+    ///         the exchange has a limitless number of tokens it can transfer.
+    TransferRequest(Token, u64),
+}
+```
+
+## Order Requests
+
+When an investor decides to exchange a token of one type for another, they
+submit a transaction to the Solana Blockchain containing an order request, which,
+if successful, is turned into an order.  orders do not expire but are
+cancellable. <!-- orders should have a timestamp to enable trade
+expiration -->  When an order is created, tokens are deducted from a token
+account and the order acts as an escrow.  The tokens are held until the
+order is fulfilled or canceled. If the direction is `To`, then the number
+of `tokens` are deducted from the primary account, if `From` then `tokens`
+multiplied by `price` are deducted from the secondary account.  orders are
+no longer valid when the number of `tokens` goes to zero, at which point they
+can no longer be used. <!-- Could support refilling orders, so order
+accounts are refilled rather than accumulating -->
+
+```rust
+/// Direction of the exchange between two tokens in a pair
+pub enum Direction {
+    /// Trade first token type (primary) in the pair 'To' the second
+    To,
+    /// Trade first token type in the pair 'From' the second (secondary)
+    From,
+}
+
+pub struct OrderRequestInfo {
+    /// Direction of trade
+    pub direction: Direction,
+
+    /// Token pair to trade
+    pub pair: TokenPair,
+
+    /// Number of tokens to exchange; refers to the primary or the secondary depending on the direction
+    pub tokens: u64,
+
+    /// The price ratio the primary price over the secondary price.  The primary price is fixed
+    /// and equal to the variable `SCALER`.
+    pub price: u64,
+
+    /// Token account to deposit tokens on successful swap
+    pub dst_account: Pubkey,
+}
+
+pub enum ExchangeInstruction {
+    /// order request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - Token account associated with this trade
+    TradeRequest(TradeRequestInfo),
+}
+
+/// Trade accounts are populated with this structure
+pub struct TradeOrderInfo {
+    /// Owner of the order
+    pub owner: Pubkey,
+    /// Direction of the exchange
+    pub direction: Direction,
+    /// Token pair indicating two tokens to exchange, first is primary
+    pub pair: TokenPair,
+    /// Number of tokens to exchange; primary or secondary depending on direction
+    pub tokens: u64,
+    /// Scaled price of the secondary token given the primary is equal to the scale value
+    /// If scale is 1 and price is 2 then ratio is 1:2 or 1 primary token for 2 secondary tokens
+    pub price: u64,
+    /// account which the tokens were source from.  The trade account holds the tokens in escrow
+    /// until either one or more part of a swap or the trade is canceled.
+    pub src_account: Pubkey,
+    /// account which the tokens the tokens will be deposited into on a successful trade
+    pub dst_account: Pubkey,
+}
+```
+
+## Order cancellations
+
+An investor may cancel a trade at anytime, but only trades they own.  If the
+cancellation is successful, any tokens held in escrow are returned to the
+account from which they came.
+
+```rust
+pub enum ExchangeInstruction {
+    /// order cancellation
+    /// key 0 - Signer
+    /// key 1 -order to cancel
+    TradeCancellation,
+}
+```
+
+## Trade swaps
+
+The Matcher is monitoring the accounts assigned to the exchange program and
+building a trade-order table.  The order table is used to identify
+matching orders which could be fulfilled.  When a match is found the
+Matcher should issue a swap request.  Swap requests may not satisfy the entirety
+of either order, but the exchange will greedily fulfill it.  Any leftover tokens
+in either account will keep the order valid for further swap requests in
+the future.
+
+Matching orders are defined by the following swap requirements:
+
+- Opposite polarity (one `To` and one `From`)
+- Operate on the same token pair
+- The price ratio of the `From` order is greater than or equal to the `To` order
+- There are sufficient tokens to perform the trade
+
+Orders can be written in the following format:
+
+`investor direction pair quantity price-ratio`
+
+For example:
+
+- `1 T AB 2 1`
+  - Investor 1 wishes to exchange 2 A tokens to B tokens at a ratio of 1 A to 1
+    B
+- `2 F AC 6 1.2`
+  - Investor 2 wishes to exchange A tokens from 6 B tokens at a ratio of 1 A
+    from 1.2 B
+
+An order table could look something like the following. Notice how the columns
+are sorted low to high and high to low, respectively.  Prices are dramatic and
+whole for clarity.
+
+|Row| To          | From       |
+|---|-------------|------------|
+| 1 | 1 T AB 2 4  | 2 F AB 2 8 |
+| 2 | 1 T AB 1 4  | 2 F AB 2 8 |
+| 3 | 1 T AB 6 6  | 2 F AB 2 7 |
+| 4 | 1 T AB 2 8  | 2 F AB 3 6 |
+| 5 | 1 T AB 2 10 | 2 F AB 1 5 |
+
+As part of a successful swap request, the exchange will credit tokens to the
+Matcher's account equal to the difference in the price ratios or the two orders.
+These tokens are considered the Matcher's profit for initiating the trade.
+
+The Matcher would initiate the following swap on the order table above:
+
+  - Row 1, To:   Investor 1 trades 2 A tokens to 8 B tokens
+  - Row 1, From: Investor 2 trades 2 A tokens from 8 B tokens
+  - Matcher takes 8 B tokens as profit
+
+Both row 1 trades are fully realized, table becomes:
+
+|Row| To          | From       |
+|---|-------------|------------|
+| 1 | 1 T AB 1 4  | 2 F AB 2 8 |
+| 2 | 1 T AB 6 6  | 2 F AB 2 7 |
+| 3 | 1 T AB 2 8  | 2 F AB 3 6 |
+| 4 | 1 T AB 2 10 | 2 F AB 1 5 |
+
+The Matcher would initiate the following swap:
+
+  - Row 1, To:   Investor 1 trades 1 A token to 4 B tokens
+  - Row 1, From: Investor 2 trades 1 A token from 4 B tokens
+  - Matcher takes 4 B tokens as profit
+
+Row 1 From is not fully realized, table becomes:
+
+|Row| To          | From       |
+|---|-------------|------------|
+| 1 | 1 T AB 6 6  | 2 F AB 1 8 |
+| 2 | 1 T AB 2 8  | 2 F AB 2 7 |
+| 3 | 1 T AB 2 10 | 2 F AB 3 6 |
+| 4 |             | 2 F AB 1 5 |
+
+The Matcher would initiate the following swap:
+
+  - Row 1, To:   Investor 1 trades 1 A token to 6 B tokens
+  - Row 1, From: Investor 2 trades 1 A token from 6 B tokens
+  - Matcher takes 2 B tokens as profit
+
+Row 1 To is now fully realized, table becomes:
+
+|Row| To          | From       |
+|---|-------------|------------|
+| 1 | 1 T AB 5 6  | 2 F AB 2 7 |
+| 2 | 1 T AB 2 8  | 2 F AB 3 5 |
+| 3 | 1 T AB 2 10 | 2 F AB 1 5 |
+
+The Matcher would initiate the following last swap:
+
+  - Row 1, To:   Investor 1 trades 2 A token to 12 B tokens
+  - Row 1, From: Investor 2 trades 2 A token from 12 B tokens
+  - Matcher takes 2 B tokens as profit
+
+Table becomes:
+
+|Row| To          | From       |
+|---|-------------|------------|
+| 1 | 1 T AB 3 6  | 2 F AB 3 5 |
+| 2 | 1 T AB 2 8  | 2 F AB 1 5 |
+| 3 | 1 T AB 2 10 |            |
+
+At this point the lowest To's price is larger than the largest From's price so
+no more swaps would be initiated until new orders came in.
+
+```rust
+pub enum ExchangeInstruction {
+    /// Trade swap request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - 'To' order
+    /// key 3 - `From` order
+    /// key 4 - Token account associated with the To Trade
+    /// key 5 - Token account associated with From trade
+    /// key 6 - Token account in which to deposit the Matcher profit from the swap.
+    SwapRequest,
+}
+
+/// Swap accounts are populated with this structure
+pub struct TradeSwapInfo {
+    /// Pair swapped
+    pub pair: TokenPair,
+    /// `To` order
+    pub to_trade_order: Pubkey,
+    /// `From` order
+    pub from_trade_order: Pubkey,
+    /// Number of primary tokens exchanged
+    pub primary_tokens: u64,
+    /// Price the primary tokens were exchanged for
+    pub primary_price: u64,
+    /// Number of secondary tokens exchanged
+    pub secondary_tokens: u64,
+    /// Price the secondary tokens were exchanged for
+    pub secondary_price: u64,
+}
+```
+
+## Exchange program operations
+
+Putting all the commands together from above, the following operations will be
+supported by the on-chain exchange program:
+
+```rust
+pub enum ExchangeInstruction {
+    /// New token account
+    /// key 0 - Signer
+    /// key 1 - New token account
+    AccountRequest,
+
+    /// Transfer tokens between two accounts
+    /// key 0 - Account to transfer tokens to
+    /// key 1 - Account to transfer tokens from.  This can be the exchange program itself,
+    ///         the exchange has a limitless number of tokens it can transfer.
+    TransferRequest(Token, u64),
+
+    /// order request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - Token account associated with this trade
+    TradeRequest(TradeRequestInfo),
+
+    /// order cancellation
+    /// key 0 - Signer
+    /// key 1 -order to cancel
+    TradeCancellation,
+
+    /// Trade swap request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - 'To' order
+    /// key 3 - `From` order
+    /// key 4 - Token account associated with the To Trade
+    /// key 5 - Token account associated with From trade
+    /// key 6 - Token account in which to deposit the Matcher profit from the swap.
+    SwapRequest,
+}
+```
+
+## Quotes and OHLCV
+
+The Matcher will provide current bid/ask price quotes based on trade actively and
+also provide OHLCV based on some time window.  The details of how the bid/ask
+price quotes are calculated are yet to be decided.
+
+## Investor strategies
+
+To make a compelling demo, the investors needs to provide interesting trade
+behavior.  Something as simple as a randomly twiddled baseline would be a
+minimum starting point.
+
+## Running the exchange
+
+The exchange bench posts trades and swaps matches as fast as it can.  
+
+You might want to bump the duration up
+to 60 seconds and the batch size to 1000 for better numbers.  You can modify those
+in client_demo/src/demo.rs::test_exchange_local_cluster.
+
+The following command runs the bench:
+
+```bash
+$ RUST_LOG=solana_bench_exchange=info cargo test --release -- --nocapture test_exchange_local_cluster
+```
+
+To also see the cluster messages:
+
+```bash
+$ RUST_LOG=solana_bench_exchange=info,solana=info cargo test --release -- --nocapture test_exchange_local_cluster
+```

-# Leader Duplicate Block Slashing
-
-This design describes how the cluster slashes leaders that produce duplicate
-blocks.
-
-Leaders that produce multiple blocks for the same slot increase the number of
-potential forks that the cluster has to resolve.
-
-## Primitives
-1. gossip_root: Nodes now gossip their current root
-2. gossip_duplicate_slots: Nodes can gossip up to `N` duplicate slot proofs.
-3. `DUPLICATE_THRESHOLD`: The minimum percentage of stake that needs to vote on a fork with version `X` of a duplicate slot, in order for that fork to become votable.
-
-## Protocol
-1. When WindowStage detects a duplicate slot proof `P`, it checks the new `gossip_root` to see if `<= 1/3` of the nodes have rooted a slot `S >= P`. If so, it pushes a proof to `gossip_duplicate_slots` to gossip. WindowStage then signals ReplayStage about this duplicate slot `S`. These proofs can be purged from gossip once the validator sees > 2/3 of people gossiping roots `R > S`.
-
-2. When ReplayStage receives the signal for a duplicate slot `S` from `1)` above, the validator monitors gossip and replay waiting for`>= DUPLICATE_THRESHOLD` votes for the same hash which implies the same version of the slot. If this conditon is met for some version with hash `H` of slot `S`, this is then known as the `duplicate_confirmed` version of the slot.
-
-Before a duplicate slot `S` is `duplicate_confirmed`, it's first excluded from the vote candidate set in the fork choice rules. In addition, ReplayStage also resets PoH to the *latest* ancestor of the *earliest* `non-duplicate/confirmed_duplicate_slot`, so that block generation can start happening on the earliest known *safe* block.
-
-Some notes about the `DUPLICATE_THRESHOLD`. In the cases below, assume `DUPLICATE_THRESHOLD = 52`:
-
-a) If less than `2 * DUPLICATE_THRESHOLD - 1` percentage of the network is malicious, then there can only be one such `duplicate_confirmed` version of the slot. With `DUPLICATE_THRESHOLD = 52`, this is
-a malcious tolerance of `4%`
-
-b) The liveness of the network is at most `1 - DUPLICATE_THRESHOLD - SWITCH_THRESHOLD`. This is because if you need at least `SWITCH_THRESHOLD` percentage of the stake voting on a different fork in order to switch off of a duplicate fork that has `< DUPLICATE_THRESHOLD` stake voting on it, and is *not* `duplicate_confirmed`. For `DUPLICATE_THRESHOLD = 52` and `DUPLICATE_THRESHOLD = 38`, this implies a liveness tolerance of `10%`.
-
-For example in the situation below, validators that voted on `2` can't vote any further on fork `2` because it's been removed from fork choice. Now slot 6 better have enough stake for a switching proof, or the network halts.
-
-```text
-    |-------- 2 (51% voted, then detected this slot was a duplicate and removed this slot from fork choice)
-0---|
-    |---------- 6 (39%)
-
-```
-
-3. Switching proofs need to be extended to allow including vote hashes from different versions of the same same slot (detected through 1). Right now this is not supported since switching proofs can
-only be built using votes from banks in BankForks, and two different versions of the same slot cannot
-simultaneously exist in BankForks. For instance:
-
-```text
-    |-------- 2
-    |
-0------------- 1 ------ 2'
-    |
-    |---------- 6
-
-```
-
-Imagine each version of slot 2 and 2' have `DUPLICATE_THRESHOLD / 2` of the votes on them, so neither duplicate can be confirmed. At most slot 6 has `1 - DUPLICATE_THRESHOLD / 2` of the votes
-on it, which is less than the switching threshold. Thus, in order for validators voting on `2` or `2'` to switch to slot 6, and make progress, they need to incorporate votes from the other version of the slot into their switching proofs.
-
-
-### The repair problem.
-Now what happens if one of the following occurs:
-
-1) Due to network blips/latencies, some validators fail to observe the gossip votes before they are overwritten by newer votes? Then some validators may conclude a slot `S` is `duplicate_confirmed` while others don't.
-
-2) Due to lockouts, no version of duplicate slot `S` reaches `duplicate_confirmed` status, but one of its descendants may reach `duplicate_confirmed` after those lockouts expire, which by definition, means `S` is also `duplicate_confirmed`.
-
-3) People who are catching up and don't see the votes in gossip encounter a dup block and can't make progress.
-
-We assume that given a network is eventually stable, if at least one correct validator observed `S` is `duplicate_confirmed`, then if `S` is part of the heaviest fork, then eventually all validators will observe some descendant of `S` is duplicate confirmed.
-
-This problem we need to solve is modeled simply by the below scenario:
-
-```text
-1 -> 2 (duplicate) -> 3 -> 4 (duplicate)
-```
-Assume the following:
-
-1. Due to gossiping duplciate proofs, we assume everyone will eventually see duplicate proofs for 2 and 4, so everyone agrees to remove them from fork choice until they are `duplicate_confirmed`.
-
-2. Due to lockouts, `> DUPLICATE_THRESHOLD` of the stake votes on 4, but not 2. This means at least `DUPLICATE_THRESHOLD` of people have the "correct" version of both slots 2 and 4.
-
-3. However, the remaining `1-DUPLICATE_THRESHOLD` of people have wrong version of 2. This means in replay, their slot 3 will be marked dead, *even though the faulty slot is 2*. The goal is to get these people on the right fork again.
-
-Possible solution:
-
-1. Change `EpochSlots` to signal when a bank is frozen, not when a slot is complete. If we see > `DUPLICATE_THRESHOLD` have frozen the dead slot 3, then we attempt recovery. Note this does not mean that all `DUPLICATE_THRESHOLD` have frozen the same version of the bank, it's just a signal to us that something may be wrong with our version of the bank.
-
-2. Recovery takes the form of a special repair request, `RepairDuplicateConfirmed(dead_slot, Vec<(Slot, Hash)>)`, which specifies a  dead slot, and then a vector of `(slot, hash)` of `N` of its latest parents.
-
-3. The repairer sees this request and responds with the correct hash only if any element of the `(slot, hash)` vector is both `duplicate_confirmed` and the hash doesn't match the requester's hash in the vector.
-
-4. Once the requester sees the "correct" hash is different than their frozen hash, they dump the block so that they can accept a new block, and ask the network for the block with the correct hash.
-
-Of course the repairer might lie to you, and you'll get the wrong version of the block, in which case you'll end up with another dead block and repeat the procedure.
