-## Getting Pull Requests Merged
-
-There is no single person assigned to watching GitHub PR queue and ushering you
-through the process. Typically, you will ask the person that wrote a component
-to review changes to it. You can find the author using `git blame` or asking on
-Discord.  When working to get your PR merged, it's most important to understand
-that changing the code is your priority and not necessarily a priority of the
-person you need an approval from. Also, while you may interact the most with
-the component author, you should aim to be inclusive of others. Providing a
-detailed problem description is the most effective means of engaging both the
-component author and other potentially interested parties.
-
-Consider opening all PRs as Draft Pull Requests first. Using a draft PR allows
-you to kickstart the CI automation, which typically takes between 10 and 30
-minutes to execute. Use that time to write a detailed problem description. Once
-the description is written and CI succeeds, click the "Ready to Review" button
-and add reviewers. Adding reviewers before CI succeeds is a fast path to losing
-reviewer engagement. Not only will they be notified and see the PR is not yet
-ready for them, they will also be bombarded them with additional notifications
-each time you push a commit to get past CI or until they "mute" the PR. Once
-muted, you'll need to reach out over some other medium, such as Discord, to
-request they have another look. When you use draft PRs, no notifications are
-sent when you push commits and edit the PR description. Use draft PRs
-liberally.  Don't bug the humans until you have gotten past the bots.
-
-### What should be in my PR description?
-
-Reviewing code is hard work and generally involves an attempt to guess the
-author's intent at various levels. Please assume reviewer time is scarce and do
-what you can to make your PR as consumable as possible. Inspired by techniques
-for writing good whitepapers, the guidance here aims to maximize reviewer
-engagement.
-
-Assume the reviewer will spend no more than a few seconds reading the PR title.
-If it doesn't describe a noteworthy change, don't expect the reviewer to click
-to see more.
-
-Next, like the abstract of a whitepaper, the reviewer will spend ~30 seconds
-reading the PR problem description. If what is described there doesn't look
-more important than competing issues, don't expect the reviewer to read on.
-
-Next, the reviewer will read the proposed changes. At this point, the reviewer
-needs to be convinced the proposed changes are a *good* solution to the problem
-described above.  If the proposed changes, not the code changes, generates
-discussion, consider closing the PR and returning with a design proposal
-instead.
-
-Finally, once the reviewer understands the problem and agrees with the approach
-to solving it, the reviewer will view the code changes. At this point, the
-reviewer is simply looking to see if the implementation actually implements
-what was proposed and if that implementation is maintainable. When a concise,
-readable test for each new code path is present, the reviewer can safely ignore
-the details of its implementation. When those tests are missing, expect to
-either lose engagement or get a pile of review comments as the reviewer
-attempts to consider every ambiguity in your implementation.
-
-### The PR Title
-
-The PR title should contain a brief summary of the change, from the perspective
-of the user. Examples of good titles:
-
-* Add rent to accounts
-* Fix out-of-memory error in validator
-* Clean up `process_message()` in runtime
-
-The conventions here are all the same as a good git commit title:
-
-* First word capitalized and in the imperative mood, not past tense ("add", not
-  "added")
-* No trailing period
-* What was done, whom it was done to, and in what context
-
-### The PR Problem Statement
-
-The git repo implements a product with various features. The problem statement
-should describe how the product is missing a feature, how a feature is
-incomplete, or how the implementation of a feature is somehow undesirable. If
-an issue being fixed already describes the problem, go ahead and copy-paste it.
-As mentioned above, reviewer time is scarce. Given a queue of PRs to review,
-the reviewer may ignore PRs that expect them to click through links to see if
-the PR warrants attention.
-
-### The Proposed Changes
-
-Typically the content under the "Proposed changes" section will be a bulleted
-list of steps taken to solve the problem. Oftentimes, the list is identical to
-the subject lines of the git commits contained in the PR. It's especially
-generous (and not expected) to rebase or reword commits such that each change
-matches the logical flow in your PR description.
 
 ### When will my PR be reviewed?
 
-PRs are typically reviewed and merged in under 7 days. If your PR has been open
+PRs are typically reviewed and merged in under 7 days. If your PR has been open for longer,

-
-Do not add reviewers to draft PRs.  GitHub doesn't automatically clear

-# Building
+Blockchain Rebuilt for Scale
+===
 
-## **1. Install rustc, cargo and rustfmt.**
+Solana&trade; is a new blockchain architecture built from the ground up for scale. The architecture supports
+up to 710 thousand transactions per second on a gigabit network.
+
+Disclaimer
+===
+
+All claims, content, designs, algorithms, estimates, roadmaps, specifications, and performance measurements described in this project are done with the author's best effort.  It is up to the reader to check and validate their accuracy and truthfulness.  Furthermore nothing in this project constitutes a solicitation for investment.
+
+Introduction
+===
+
+It's possible for a centralized database to process 710,000 transactions per second on a standard gigabit network if the transactions are, on average, no more than 176 bytes. A centralized database can also replicate itself and maintain high availability without significantly compromising that transaction rate using the distributed system technique known as Optimistic Concurrency Control [\[H.T.Kung, J.T.Robinson (1981)\]](http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.65.4735). At Solana, we're demonstrating that these same theoretical limits apply just as well to blockchain on an adversarial network. The key ingredient? Finding a way to share time when nodes can't trust one-another. Once nodes can trust time, suddenly ~40 years of distributed systems research becomes applicable to blockchain!
+
+> Perhaps the most striking difference between algorithms obtained by our method and ones based upon timeout is that using timeout produces a traditional distributed algorithm in which the processes operate asynchronously, while our method produces a globally synchronous one in which every process does the same thing at (approximately) the same time. Our method seems to contradict the whole purpose of distributed processing, which is to permit different processes to operate independently and perform different functions. However, if a distributed system is really a single system, then the processes must be synchronized in some way. Conceptually, the easiest way to synchronize processes is to get them all to do the same thing at the same time. Therefore, our method is used to implement a kernel that performs the necessary synchronization--for example, making sure that two different processes do not try to modify a file at the same time. Processes might spend only a small fraction of their time executing the synchronizing kernel; the rest of the time, they can operate independently--e.g., accessing different files. This is an approach we have advocated even when fault-tolerance is not required. The method's basic simplicity makes it easier to understand the precise properties of a system, which is crucial if one is to know just how fault-tolerant the system is. [\[L.Lamport (1984)\]](http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.71.1078)
+
+Furthermore, and much to our surprise, it can be implemented using a mechanism that has existed in Bitcoin since day one. The Bitcoin feature is called nLocktime and it can be used to postdate transactions using block height instead of a timestamp. As a Bitcoin client, you'd use block height instead of a timestamp if you don't trust the network. Block height turns out to be an instance of what's being called a Verifiable Delay Function in cryptography circles. It's a cryptographically secure way to say time has passed. In Solana, we use a far more granular verifiable delay function, a SHA 256 hash chain, to checkpoint the ledger and coordinate consensus. With it, we implement Optimistic Concurrency Control and are now well en route towards that theoretical limit of 710,000 transactions per second.

+Remote Testnets
+---
+
+We maintain several testnets:
+
+* `testnet` - public stable testnet accessible via testnet.solana.com, with an https proxy for web apps at api.testnet.solana.com. Runs 24/7
+* `testnet-beta` - public beta channel testnet accessible via beta.testnet.solana.com. Runs 24/7

+* `testnet-perf` - permissioned stable testnet running a 24/7 soak test
+* `testnet-beta-perf` - permissioned beta channel testnet running a multi-hour soak test weekday mornings
+* `testnet-edge-perf` - permissioned edge channel testnet running a multi-hour soak test weekday mornings
+
+## Deploy process
+
+They are deployed with the `ci/testnet-manager.sh` script through a list of [scheduled
+buildkite jobs](https://buildkite.com/solana-labs/testnet-management/settings/schedules).
+Each testnet can be manually manipulated from buildkite as well.
+
+## How do I reset the testnet?
+Manually trigger the [testnet-management](https://buildkite.com/solana-labs/testnet-management) pipeline
+and when prompted select the desired testnet
+
+## How can I scale the tx generation rate?
+
+Increase the TX rate by increasing the number of cores on the client machine which is running
+`bench-tps` or run multiple clients. Decrease by lowering cores or using the rayon env
+variable `RAYON_NUM_THREADS=<xx>`
+
+## How can I test a change on the testnet?
+
+Currently, a merged PR is the only way to test a change on the testnet.  But you
+can run your own testnet using the scripts in the `net/` directory.
+
+## Adjusting the number of clients or validators on the testnet

+## Release Steps
 
-### Create the new branch
+### Changing channels
-1. Check out the latest commit on `master` branch:
+
-    ```
+When cutting a new channel branch these pre-steps are required:
-    git fetch --all

+1. Create the branch.  The name should be "v" + the first 2 "version" fields
-1. Determine the new branch name.  The name should be "v" + the first 2 version fields
    from Cargo.toml.  For example, a Cargo.toml with version = "0.9.0" implies
    the next branch name is "v0.9".

-unresolved issues still in the `X.Y.Z` milestone, then close the `X.Y.Z` milestone.

-### Verify release automation success
-Go to [Solana Releases](https://github.com/solana-labs/solana/releases) and click on the latest release that you just published.
-Verify that all of the build artifacts are present, then the uncheck **"This is a pre-release"** for the release.
-
-Build artifacts can take up to 60 minutes after creating the tag before
-appearing.  To check for progress:
-* The `solana-secondary` Buildkite pipeline handles creating the Linux release artifacts and updated crates.  Look for a job under the tag name of the release: https://buildkite.com/solana-labs/solana-secondary.
-* The macOS and Windows release artifacts are produced by Travis CI: https://travis-ci.com/github/solana-labs/solana/branches
-
-[Crates.io](https://crates.io/crates/solana) should have an updated Solana version.  This can take 2-3 hours, and sometimes fails in the `solana-secondary` job.
-If this happens and the error is non-fatal, click "Retry" on the "publish crate" job

-## 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
-```

+# Blockstreamer
+
+Solana supports a node type called an *blockstreamer*. This fullnode variation
+is intended for applications that need to observe the data plane without

+
+A blockstreamer runs without a vote signer, and can optionally stream ledger
+entries out to a Unix domain socket as they are processed. The JSON-RPC service
+still functions as on any other node.
+
+To run a blockstreamer, include the argument `no-signer` and (optional)
+`blockstream` socket location:
+
+```bash
+$ ./multinode-demo/fullnode-x.sh --no-signer --blockstream <SOCKET>

+# Blocktree
+
+After a block reaches finality, all blocks from that one on down
+to the genesis block form a linear chain with the familiar name
+blockchain. Until that point, however, the validator must maintain all
+potentially valid chains, called *forks*. The process by which forks
+naturally form as a result of leader rotation is described in
+[fork generation](fork-generation.md). The *blocktree* data structure
+described here is how a validator copes with those forks until blocks
+are finalized.
+
+The blocktree allows a validator to record every blob it observes
+on the network, in any order, as long as the blob is signed by the expected
+leader for a given slot.
+
+Blobs are moved to a fork-able key space the tuple of `leader slot` + `blob
+index` (within the slot).  This permits the skip-list structure of the Solana
+protocol to be stored in its entirety, without a-priori choosing which fork to
+follow, which Entries to persist or when to persist them.
+
+Repair requests for recent blobs are served out of RAM or recent files and out
+of deeper storage for less recent blobs, as implemented by the store backing
+Blocktree.
+
+### Functionalities of Blocktree
+
+1. Persistence: the Blocktree lives in the front of the nodes verification
+   pipeline, right behind network receive and signature verification.  If the
+blob received is consistent with the leader schedule (i.e. was signed by the
+leader for the indicated slot), it is immediately stored.
+2. Repair: repair is the same as window repair above, but able to serve any
+   blob that's been received. Blocktree stores blobs with signatures,
+preserving the chain of origination.
+3. Forks: Blocktree supports random access of blobs, so can support a
+   validator's need to rollback and replay from a Bank checkpoint.
+4. Restart: with proper pruning/culling, the Blocktree can be replayed by
+   ordered enumeration of entries from slot 0.  The logic of the replay stage
+(i.e. dealing with forks) will have to be used for the most recent entries in
+the Blocktree.
+
+### Blocktree Design
+
+1. Entries in the Blocktree are stored as key-value pairs, where the key is the concatenated
+slot index and blob index for an entry, and the value is the entry data. Note blob indexes are zero-based for each slot (i.e. they're slot-relative).
+
+2. The Blocktree maintains metadata for each slot, in the `SlotMeta` struct containing:
+      * `slot_index` - The index of this slot
+      * `num_blocks` - The number of blocks in the slot (used for chaining to a previous slot)
+      * `consumed` - The highest blob index `n`, such that for all `m < n`, there exists a blob in this slot with blob index equal to `n` (i.e. the highest consecutive blob index).
+      * `received` - The highest received blob index for the slot
+      * `next_slots` - A list of future slots this slot could chain to. Used when rebuilding
+      the ledger to find possible fork points.
+      * `last_index` - The index of the blob that is flagged as the last blob for this slot. This flag on a blob will be set by the leader for a slot when they are transmitting the last blob for a slot.
+      * `is_rooted` - True iff every block from 0...slot forms a full sequence without any holes. We can derive is_rooted for each slot with the following rules. Let slot(n) be the slot with index `n`, and slot(n).is_full() is true if the slot with index `n` has all the ticks expected for that slot. Let is_rooted(n) be the statement that "the slot(n).is_rooted is true". Then:
+
+      is_rooted(0)
+      is_rooted(n+1) iff (is_rooted(n) and slot(n).is_full()
+
+3. Chaining - When a blob for a new slot `x` arrives, we check the number of blocks (`num_blocks`) for that new slot (this information is encoded in the blob). We then know that this new slot chains to slot `x - num_blocks`.
+
+4. Subscriptions - The Blocktree records a set of slots that have been "subscribed" to. This means entries that chain to these slots will be sent on the Blocktree channel for consumption by the ReplayStage. See the `Blocktree APIs` for details.
+
+5. Update notifications - The Blocktree notifies listeners when slot(n).is_rooted is flipped from false to true for any `n`.
+
+### Blocktree APIs
+
+The Blocktree offers a subscription based API that ReplayStage uses to ask for entries it's interested in. The entries will be sent on a channel exposed by the Blocktree. These subscription API's are as follows:
+   1. `fn get_slots_since(slot_indexes: &[u64]) -> Vec<SlotMeta>`: Returns new slots connecting to any element of the list `slot_indexes`.
+
+   2. `fn get_slot_entries(slot_index: u64, entry_start_index: usize, max_entries: Option<u64>) -> Vec<Entry>`: Returns the entry vector for the slot starting with `entry_start_index`, capping the result at `max` if `max_entries == Some(max)`, otherwise, no upper limit on the length of the return vector is imposed.
+
+Note: Cumulatively, this means that the replay stage will now have to know when a slot is finished, and subscribe to the next slot it's interested in to get the next set of entries. Previously, the burden of chaining slots fell on the Blocktree.
+
+### Interfacing with Bank
+
+The bank exposes to replay stage:
+
+ 1. `prev_hash`: which PoH chain it's working on as indicated by the hash of the last
+    entry it processed
+ 2. `tick_height`: the ticks in the PoH chain currently being verified by this
+    bank
+ 3. `votes`: a stack of records that contain:
+
+    1. `prev_hashes`: what anything after this vote must chain to in PoH
+    2. `tick_height`: the tick height at which this vote was cast
+    3. `lockout period`: how long a chain must be observed to be in the ledger to
+       be able to be chained below this vote
+
+Replay stage uses Blocktree APIs to find the longest chain of entries it can
+hang off a previous vote.  If that chain of entries does not hang off the
+latest vote, the replay stage rolls back the bank to that vote and replays the
+chain from there.
+
+### Pruning Blocktree
+
+Once Blocktree entries are old enough, representing all the possible forks
+becomes less useful, perhaps even problematic for replay upon restart.  Once a
+validator's votes have reached max lockout, however, any Blocktree contents
+that are not on the PoH chain for that vote for can be pruned, expunged.
+
+Replicator nodes will be responsible for storing really old ledger contents,
+and validators need only persist their bank periodically.

+# Cluster Test Framework
+
+This document proposes the Cluster Test Framework (CTF).  CTF is a test harness
+that allows tests to execute against a local, in-process cluster or a
+deployed cluster.
+
+## Motivation
+
+The goal of CTF is to provide a framework for writing tests independent of where
+and how the cluster is deployed. Regressions can be captured in these tests and
+the tests can be run against deployed clusters to verify the deployment.  The
+focus of these tests should be on cluster stability, consensus, fault tolerance,
+API stability.
+
+Tests should verify a single bug or scenario, and should be written with the
+least amount of internal plumbing exposed to the test.
+
+## Design Overview
+
+Tests are provided an entry point, which is a `contact_info::ContactInfo`
+structure, and a keypair that has already been funded.
+
+Each node in the cluster is configured with a `fullnode::FullnodeConfig` at boot
+time.  At boot time this configuration specifies any extra cluster configuration
+required for the test. The cluster should boot with the configuration when it
+is run in-process or in a data center.
+
+Once booted, the test will discover the cluster through a gossip entry point and
+configure any runtime behaviors via fullnode RPC.
+
+## Test Interface
+
+Each CTF test starts with an opaque entry point and a funded keypair.  The test
+should not depend on how the cluster is deployed, and should be able to exercise
+all the cluster functionality through the publicly available interfaces.
+
+```rust,ignore
+use crate::contact_info::ContactInfo;
+use solana_sdk::signature::{Keypair, KeypairUtil};
+pub fn test_this_behavior(
+    entry_point_info: &ContactInfo,
+    funding_keypair: &Keypair,
+    num_nodes: usize,
+)
+```
+
+
+## Cluster Discovery
+
+At test start, the cluster has already been established and is fully connected.
+The test can discover most of the available nodes over a few second.
+
+```rust,ignore
+use crate::gossip_service::discover;
+
+// Discover the cluster over a few seconds.
+let cluster_nodes = discover(&entry_point_info, num_nodes);
+```
+
+## Cluster Configuration
+
+To enable specific scenarios, the cluster needs to be booted with special
+configurations.  These configurations can be captured in
+`fullnode::FullnodeConfig`.
+
+For example:
+
+```rust,ignore
+let mut fullnode_config = FullnodeConfig::default();
+fullnode_config.rpc_config.enable_fullnode_exit = true;
+let local = LocalCluster::new_with_config(
+                num_nodes,
+                10_000,
+                100,
+                &fullnode_config
+                );
+```
+
+## How to design a new test
+
+For example, there is a bug that shows that the cluster fails when it is flooded
+with invalid advertised gossip nodes.  Our gossip library and protocol may
+change, but the cluster still needs to stay resilient to floods of invalid
+advertised gossip nodes.
+
+Configure the RPC service:
+
+```rust,ignore
+let mut fullnode_config = FullnodeConfig::default();
+fullnode_config.rpc_config.enable_rpc_gossip_push = true;
+fullnode_config.rpc_config.enable_rpc_gossip_refresh_active_set = true;
+```
+
+Wire the RPCs and write a new test:
+
+```rust,ignore
+pub fn test_large_invalid_gossip_nodes(
+    entry_point_info: &ContactInfo,
+    funding_keypair: &Keypair,
+    num_nodes: usize,
+) {
+    let cluster = discover(&entry_point_info, num_nodes);
+
+    // Poison the cluster.
+    let mut client = create_client(entry_point_info.client_facing_addr(), FULLNODE_PORT_RANGE);
+    for _ in 0..(num_nodes * 100) {
+        client.gossip_push(
+            cluster_info::invalid_contact_info()
+        );
+    }
+    sleep(Durration::from_millis(1000));
+
+    // Force refresh of the active set.
+    for node in &cluster {
+        let mut client = create_client(node.client_facing_addr(), FULLNODE_PORT_RANGE);
+        client.gossip_refresh_active_set();
+    }
+
+    // Verify that spends still work.
+    verify_spends(&cluster);
+}

+# A Solana Cluster
+
+A Solana cluster is a set of fullnodes working together to serve client
+transactions and maintain the integrity of the ledger. Many clusters may
+coexist. When two clusters share a common genesis block, they attempt to
+converge. Otherwise, they simply ignore the existence of the other.
+Transactions sent to the wrong one are quietly rejected. In this chapter, we'll
+discuss how a cluster is created, how nodes join the cluster, how they share
+the ledger, how they ensure the ledger is replicated, and how they cope with
+buggy and malicious nodes.
+
+## Creating a Cluster
+
+Before starting any fullnodes, one first needs to create a *genesis block*.
+The block contains entries referencing two public keys, a *mint* and a
+*bootstrap leader*. The fullnode holding the bootstrap leader's secret key is
+responsible for appending the first entries to the ledger. It initializes its
+internal state with the mint's account. That account will hold the number of
+native tokens defined by the genesis block. The second fullnode then contacts
+the bootstrap leader to register as a *validator* or *replicator*. Additional
+fullnodes then register with any registered member of the cluster.
+
+A validator receives all entries from the leader and submits votes confirming
+those entries are valid. After voting, the validator is expected to store those
+entries until replicator nodes submit proofs that they have stored copies of
+it. Once the validator observes a sufficient number of copies exist, it deletes
+its copy.
+
+## Joining a Cluster
+
+Fullnodes and replicators enter the cluster via registration messages sent to
+its *control plane*. The control plane is implemented using a *gossip*
+protocol, meaning that a node may register with any existing node, and expect
+its registration to propagate to all nodes in the cluster. The time it takes
+for all nodes to synchronize is proportional to the square of the number of
+nodes participating in the cluster. Algorithmically, that's considered very
+slow, but in exchange for that time, a node is assured that it eventually has
+all the same information as every other node, and that that information cannot
+be censored by any one node.
+
+## Sending Transactions to a Cluster
+
+Clients send transactions to any fullnode's Transaction Processing Unit (TPU)
+port. If the node is in the validator role, it forwards the transaction to the
+designated leader. If in the leader role, the node bundles incoming
+transactions, timestamps them creating an *entry*, and pushes them onto the
+cluster's *data plane*. Once on the data plane, the transactions are validated
+by validator nodes and replicated by replicator nodes, effectively appending
+them to the ledger.
+
+## Confirming Transactions
+
+A Solana cluster is capable of subsecond *confirmation* for up to 150 nodes
+with plans to scale up to hundreds of thousands of nodes. Once fully
+implemented, confirmation times are expected to increase only with the
+logarithm of the number of validators, where the logarithm's base is very high.
+If the base is one thousand, for example, it means that for the first thousand
+nodes, confirmation will be the duration of three network hops plus the time it
+takes the slowest validator of a supermajority to vote. For the next million
+nodes, confirmation increases by only one network hop.
+
+Solana defines confirmation as the duration of time from when the leader
+timestamps a new entry to the moment when it recognizes a supermajority of
+ledger votes.
+
+A gossip network is much too slow to achieve subsecond confirmation once the
+network grows beyond a certain size. The time it takes to send messages to all
+nodes is proportional to the square of the number of nodes. If a blockchain
+wants to achieve low confirmation and attempts to do it using a gossip network,
+it will be forced to centralize to just a handful of nodes.
+
+Scalable confirmation can be achieved using the follow combination of
+techniques:
+
+1. Timestamp transactions with a VDF sample and sign the timestamp.
+2. Split the transactions into batches, send each to separate nodes and have
+   each node share its batch with its peers.
+3. Repeat the previous step recursively until all nodes have all batches.
+
+Solana rotates leaders at fixed intervals, called *slots*. Each leader may only
+produce entries during its allotted slot. The leader therefore timestamps
+transactions so that validators may lookup the public key of the designated
+leader. The leader then signs the timestamp so that a validator may verify the
+signature, proving the signer is owner of the designated leader's public key.
+
+Next, transactions are broken into batches so that a node can send transactions
+to multiple parties without making multiple copies. If, for example, the leader
+needed to send 60 transactions to 6 nodes, it would break that collection of 60
+into batches of 10 transactions and send one to each node. This allows the
+leader to put 60 transactions on the wire, not 60 transactions for each node.
+Each node then shares its batch with its peers. Once the node has collected all
+6 batches, it reconstructs the original set of 60 transactions.
+
+A batch of transactions can only be split so many times before it is so small
+that header information becomes the primary consumer of network bandwidth. At
+the time of this writing, the approach is scaling well up to about 150
+validators. To scale up to hundreds of thousands of validators, each node can
+apply the same technique as the leader node to another set of nodes of equal
+size. We call the technique *data plane fanout*; learn more in the [data plan
+fanout](data-plane-fanout.md) section.

+# Data Plane Fanout
+
+A Solana cluster uses a multi-layer mechanism called *data plane fanout* to
+broadcast transaction blobs to all nodes in a very quick and efficient manner.
+In order to establish the fanout, the cluster divides itself into small
+collections of nodes, called *neighborhoods*. Each node is responsible for
+sharing any data it receives with the other nodes in its neighborhood, as well
+as propagating the data on to a small set of nodes in other neighborhoods.
+
+During its slot, the leader node distributes blobs between the validator nodes
+in one neighborhood (layer 1). Each validator shares its data within its
+neighborhood, but also retransmits the blobs to one node in each of multiple
+neighborhoods in the next layer (layer 2). The layer-2 nodes each share their
+data with their neighborhood peers, and retransmit to nodes in the next layer,
+etc, until all nodes in the cluster have received all the blobs.
+
+<img alt="Two layer cluster" src="img/data-plane.svg" class="center"/>
+
+## Neighborhood Assignment - Weighted Selection
+
+In order for data plane fanout to work, the entire cluster must agree on how the
+cluster is divided into neighborhoods. To achieve this, all the recognized
+validator nodes (the TVU peers) are sorted by stake and stored in a list. This
+list is then indexed in different ways to figure out neighborhood boundaries and
+retransmit peers. For example, the leader will simply select the first nodes to
+make up layer 1. These will automatically be the highest stake holders, allowing
+the heaviest votes to come back to the leader first. Layer-1 and lower-layer
+nodes use the same logic to find their neighbors and lower layer peers.
+
+## Layer and Neighborhood Structure
+
+The current leader makes its initial broadcasts to at most `DATA_PLANE_FANOUT`
+nodes. If this layer 1 is smaller than the number of nodes in the cluster, then
+the data plane fanout mechanism adds layers below. Subsequent layers follow
+these constraints to determine layer-capacity: Each neighborhood contains
+`NEIGHBORHOOD_SIZE` nodes and each layer may have up to `DATA_PLANE_FANOUT/2`
+neighborhoods.
+
+As mentioned above, each node in a layer only has to broadcast its blobs to its
+neighbors and to exactly 1 node in each next-layer neighborhood, instead of to
+every TVU peer in the cluster. In the default mode, each layer contains
+`DATA_PLANE_FANOUT/2` neighborhoods. The retransmit mechanism also supports a
+second, `grow`, mode of operation that squares the number of neighborhoods
+allowed each layer. This dramatically reduces the number of layers needed to
+support a large cluster, but can also have a negative impact on the network
+pressure on each node in the lower layers. A good way to think of the default
+mode (when `grow` is disabled) is to imagine it as chain of layers, where the
+leader sends blobs to layer-1 and then layer-1 to layer-2 and so on, the `layer
+capacities` remain constant, so all layers past layer-2 will have the same
+number of nodes until the whole cluster is covered. When `grow` is enabled, this
+becomes a traditional fanout where layer-3 will have the square of the number of
+nodes in layer-2 and so on.
+
+#### Configuration Values
+
+`DATA_PLANE_FANOUT` - Determines the size of layer 1. Subsequent
+layers have `DATA_PLANE_FANOUT/2` neighborhoods when `grow` is inactive.
+
+`NEIGHBORHOOD_SIZE` - The number of nodes allowed in a neighborhood.
+Neighborhoods will fill to capacity before new ones are added, i.e if a
+neighborhood isn't full, it _must_ be the last one.
+
+`GROW_LAYER_CAPACITY` - Whether or not retransmit should be behave like a
+_traditional fanout_, i.e if each additional layer should have growing
+capacities. When this mode is disabled (default), all layers after layer 1 have
+the same capacity, keeping the network pressure on all nodes equal.
+
+Currently, configuration is set when the cluster is launched. In the future,
+these parameters may be hosted on-chain, allowing modification on the fly as the
+cluster sizes change.
+
+## Neighborhoods
+
+The following diagram shows how two neighborhoods in different layers interact.
+What this diagram doesn't capture is that each neighbor actually receives
+blobs from one validator per neighborhood above it. This means that, to
+cripple a neighborhood, enough nodes (erasure codes +1 per neighborhood) from
+the layer above need to fail.  Since multiple neighborhoods exist in the upper
+layer and a node will receive blobs from a node in each of those neighborhoods,
+we'd need a big network failure in the upper layers to end up with incomplete
+data.

+# Creating Signing Services with Drones
+
+This chapter defines an off-chain service called a *drone*, which acts as
+custodian of a user's private key. In its simplest form, it can be used to
+create *airdrop* transactions, a token transfer from the drone's account to a
+client's account.
+
+## Signing Service
+
+A drone is a simple signing service. It listens for requests to sign
+*transaction data*.  Once received, the drone validates the request however it
+sees fit. It may, for example, only accept transaction data with a
+`SystemInstruction::Move` instruction transferring only up to a certain amount
+of tokens. If the drone accepts the transaction, it returns an `Ok(Signature)`
+where `Signature` is a signature of the transaction data using the drone's
+private key. If it rejects the transaction data, it returns a `DroneError`
+describing why.
+
+
+## Examples
+
+### Granting access to an on-chain game
+
+Creator of on-chain game tic-tac-toe hosts a drone that responds to airdrop
+requests containing an `InitGame` instruction. The drone signs the transaction
+data in the request and returns it, thereby authorizing its account to pay the
+transaction fee and as well as seeding the game's account with enough tokens to
+play it. The user then creates a transaction for its transaction data and the
+drones signature and submits it to the Solana cluster. Each time the user
+interacts with the game, the game pays the user enough tokens to pay the next
+transaction fee to advance the game. At that point, the user may choose to keep
+the tokens instead of advancing the game. If the creator wants to defend
+against that case, they could require the user to return to the drone to sign
+each instruction.
+
+### Worldwide airdrop of a new token
+
+Creator of a new on-chain token (ERC-20 interface), may wish to do a worldwide
+airdrop to distribute its tokens to millions of users over just a few seconds.
+That drone cannot spend resources interacting with the Solana cluster. Instead,
+the drone should only verify the client is unique and human, and then return
+the signature. It may also want to listen to the Solana cluster for recent
+entry IDs to support client retries and to ensure the airdrop is targeting the
+desired cluster.
+
+
+## Attack vectors
+
+### Invalid recent_blockhash
+
+The drone may prefer its airdrops only target a particular Solana cluster.  To
+do that, it listens to the cluster for new entry IDs and ensure any requests
+reference a recent one.
+
+Note: to listen for new entry IDs assumes the drone is either a fullnode or a
+*light* client. At the time of this writing, light clients have not been
+implemented and no proposal describes them. This document assumes one of the
+following approaches be taken:
+
+1. Define and implement a light client
+2. Embed a fullnode
+3. Query the jsonrpc API for the latest last id at a rate slightly faster than
+   ticks are produced.
+
+### Double spends
+
+A client may request multiple airdrops before the first has been submitted to
+the ledger. The client may do this maliciously or simply because it thinks the
+first request was dropped. The drone should not simply query the cluster to
+ensure the client has not already received an airdrop. Instead, it should use
+`recent_blockhash` to ensure the previous request is expired before signing another.
+Note that the Solana cluster will reject any transaction with a `recent_blockhash`
+beyond a certain *age*.
+
+### Denial of Service
+
+If the transaction data size is smaller than the size of the returned signature
+(or descriptive error), a single client can flood the network.  Considering
+that a simple `Move` operation requires two public keys (each 32 bytes) and a
+`fee` field, and that the returned signature is 64 bytes (and a byte to
+indicate `Ok`), consideration for this attack may not be required.
+
+In the current design, the drone accepts TCP connections. This allows clients
+to DoS the service by simply opening lots of idle connections. Switching to UDP
+may be preferred. The transaction data will be smaller than a UDP packet since
+the transaction sent to the Solana cluster is already pinned to using UDP.

+## Attack Vectors
+
+### Colluding validation and replication clients
+
+A colluding validation-client, may take the strategy to mark PoReps from non-colluding replicator nodes as invalid as an attempt to maximize the rewards for the colluding replicator nodes. In this case, it isn’t feasible for the offended-against replicator nodes to petition the network for resolution as this would result in a network-wide vote on each offending PoRep and create too much overhead for the network to progress adequately. Also, this mitigation attempt would still be vulnerable to a >= 51% staked colluder.
+
+Alternatively, transaction fees from submitted PoReps are pooled and distributed across validation-clients in proportion to the number of valid PoReps discounted by the number of invalid PoReps as voted by each validator-client. Thus invalid votes are directly dis-incentivized through this reward channel. Invalid votes that are revealed by replicator nodes as fishing PoReps, will not be discounted from the payout PoRep count.
+
+Another collusion attack involves a validator-client who may take the strategy to ignore invalid PoReps from colluding replicator and vote them as valid. In this case, colluding replicator-clients would not have to store the data while still receiving rewards for validated PoReps. Additionally, colluding validator nodes would also receive rewards for validating these PoReps. To mitigate this attack, validators must randomly sample PoReps corresponding to the ledger block they are validating and because of this, there will be multiple validators that will receive the colluding replicator’s invalid submissions. These non-colluding validators will be incentivized to mark these PoReps as invalid as they have no way to determine whether the proposed invalid PoRep is actually a fishing PoRep, for which a confirmation vote would result in the validator’s stake being slashed.
+
+In this case, the proportion of time a colluding pair will be successful has an upper limit determined by the % of stake of the network claimed by the colluding validator. This also sets bounds to the value of such an attack. For example, if a colluding validator controls 10% of the total validator stake, transaction fees will be lost (likely sent to mining pool) by the colluding replicator 90% of the time and so the attack vector is only profitable if the per-PoRep reward at least 90% higher than the average PoRep transaction fee. While, probabilistically, some colluding replicator-client PoReps will find their way to colluding validation-clients, the network can also monitor rates of paired (validator + replicator) discrepancies in voting patterns and censor identified colluders in these cases.

+## Economic Sustainability
+
+Long term economic sustainability is one of the guiding principles of Solana’s economic design. While it is impossible to predict how decentralized economies will develop over time, especially economies with flexible decentralized governances, we can arrange economic components such that, under certain conditions, a sustainable economy may take shape in the long term. In the case of Solana’s network, these components take the form of the remittances and deposits into and out of the reserve ‘mining pool’.
+
+The dominant remittances from the Solana mining pool are validator and replicator rewards. The deposit mechanism is a flat, protocol-specified and adjusted, % of each transaction fee.
+
+The Replicator rewards are to be delivered to replicators from the mining pool after successful PoRep validation. The per-PoRep reward amount is determined as a function of the total network storage redundancy at the time of the PoRep validation and the network goal redundancy. This function is likely to take the form of a discount from a base reward to be delivered when the network has achieved and maintained its goal redundancy. An example of such a reward function is shown in **Figure 3**
+
+<!-- ![image alt text](porep_reward.png) -->
+<p style="text-align:center;"><img src="img/porep_reward.png" alt="==PoRep Reward Curve ==" width="800"/></p>
+
+**Figure 3**: Example PoRep reward design as a function of global network storage redundancy.
+
+In the example shown in Figure 1, multiple per PoRep base rewards are explored (as a % of Tx Fee) to be delivered when the global ledger replication redundancy meets 10X. When the global ledger replication redundancy is less than 10X, the base reward is discounted as a function of the square of the ratio of the actual ledger replication redundancy to the goal redundancy (i.e. 10X).
+
+The other protocol-based remittance goes to validation-clients as a reward distributed in proportion to stake-weight for voting to validate the ledger state. The functional issuance of this reward is described in [State-validation Protocol-based Rewards](ed_vce_state_validation_protocol_based_rewards.md) and is designed to reduce over time until validators are incentivized solely through collection of transaction fees. Therefore, in the long-run, protocol-based rewards to replication-nodes will be the only remittances from the mining pool, and will have to be countered by the portion of each non-PoRep transaction fee that is directed back into the mining pool. I.e. for a long-term self-sustaining economy, replicator-client rewards must be subsidized through a minimum fee on each non-PoRep transaction pre-allocated to the mining pool.  Through this constraint, we can write the following inequality:

+## Economic Design Overview
+
+Solana’s crypto-economic system is designed to promote a healthy, long term self-sustaining economy with participant incentives aligned to the security and decentralization of the network. The main participants in this economy are validation-clients and replication-clients. Their contributions to the network, state validation and data storage respectively, and their requisite remittance mechanisms are discussed below.
+
+The main channels of participant remittances are referred to as protocol-based rewards and transaction fees. Protocol-based rewards are protocol-derived issuances from a network-controlled reserve of tokens (sometimes referred to as the ‘mining pool’). These rewards will constitute the total reward delivered to replication clients and a portion of the total rewards for validation clients, the remaining sourced from transaction fees. In the early days of the network, it is likely that protocol-based rewards, deployed based on predefined issuance schedule, will drive the majority of participant incentives to join the network.
+
+These protocol-based rewards, to be distributed to participating validation and replication clients, are to be specified as annual interest rates calculated per, real-time, Solana epoch [DEFINITION]. As discussed further below, the issuance rates are determined as a function of total network validator staked percentage and total replication provided by replicators in each previous epoch. The choice for validator and replicator client rewards to be based on participation rates, rather than a global fixed inflation or interest rate, emphasizes a protocol priority of overall economic security, rather than monetary supply predictability. Due to Solana’s hard total supply cap of 1B tokens and the bounds of client participant rates in the protocol, we believe that global interest, and supply issuance, scenarios should be able to be modeled with reasonable uncertainties.
+
+Transaction fees are market-based participant-to-participant transfers, attached to network interactions as a necessary motivation and compensation for the inclusion and execution of a proposed transaction (be it a state execution or proof-of-replication verification). A mechanism for continuous and long-term funding of the mining pool through a pre-dedicated portion of transaction fees is also discussed below.
+
+A high-level schematic of Solana’s crypto-economic design is shown below in **Figure 1**. The specifics of validation-client economics are described in sections: [Validation-client Economics](ed_validation_client_economics.md), [State-validation Protocol-based Rewards](ed_vce_state_validation_protocol_based_rewards.md), [State-validation Transaction Fees](ed_vce_state_validation_transaction_fees.md) and [Replication-validation Transaction Fees](ed_vce_replication_validation_transaction_fees.md). Also, the chapter titled [Validation Stake Delegation](ed_vce_validation_stake_delegation.md) closes with a discussion of validator delegation opportunties and marketplace. The [Replication-client Economics](ed_replication_client_economics.md) chapter will review the Solana network design for global ledger storage/redundancy and replicator-client economics ([Storage-replication rewards](ed_rce_storage_replication_rewards.md)) along with a replicator-to-validator delegation mechanism designed to aide participant on-boarding into the Solana economy discussed in [Replication-client Reward Auto-delegation](ed_rce_replication_client_reward_auto_delegation.md). The [Economic Sustainability](ed_economic_sustainability.md) section dives deeper into Solana’s design for long-term economic sustainability and outlines the constraints and conditions for a self-sustaining economy. Finally, in chapter [Attack Vectors](ed_attack_vectors.md), various attack vectors will be described and potential vulnerabilities explored and parameterized.

+### Replication-client Reward Auto-delegation
+
+The ability for Solana network participant’s to earn rewards by providing storage service is a unique on-boarding path that requires little hardware overhead and minimal upfront capital. It offers an avenue for individuals with extra-storage space on their home laptops or PCs to contribute to the security of the network and become integrated into the Solana economy.
+
+To enhance this on-boarding ramp and facilitate further participation and investment in the Solana economy, replication-clients have the opportunity to auto-delegate their rewards to validation-clients of their choice. Much like the automatic reinvestment of stock dividends, in this scenario, a replicator-client can earn Solana tokens by providing some storage capacity to the network (i.e. via submitting valid PoReps), have the protocol-based rewards automatically assigned as delegation to a staked validator node and therefore earning interest in the validation-client reward pool.
