-        Steps to add a new feature are outlined below. Note that these steps only cover
-        the process of getting a feature into the core Solana code.
-
-        - For features that are unambiguously good (ie bug fixes), these steps are sufficient.
-
-        - For features that should go up for community vote (ie fee structure changes), more
-        information on the additional steps to follow can be found at:
-        <https://spl.solana.com/feature-proposal#feature-proposal-life-cycle>
-
-        1. Generate a new keypair with `solana-keygen new --outfile feature.json --no-passphrase`
-            - Keypairs should be held by core contributors only. If you're a non-core contirbutor going
-            through these steps, the PR process will facilitate a keypair holder being picked. That
-            person will generate the keypair, provide pubkey for PR, and ultimately enable the feature.
-
-        2. Add a public module for the feature, specifying keypair pubkey as the id with
-        `solana_sdk::declare_id!()` within the module. Additionally, add an entry to `FEATURE_NAMES` map.
-
-        3. Add desired logic to check for and switch on feature availability.

 ### How big is too big?
 
-If there are no functional changes, PRs can be very large and that's no
-problem. If, however, your changes are making meaningful changes or additions,
-then about 1,000 lines of changes is about the most you should ask a Solana
-maintainer to review.

+however, your changes are making meaningful changes or additions, then about 1,000 lines of
+changes is about the most you should ask a Solana maintainer to review.
 
 ### Should I send small PRs as I develop large, new components?
 
-Add only code to the codebase that is ready to be deployed. If you are building
-a large library, consider developing it in a separate git repository. When it
-is ready to be integrated, the Solana maintainers will work with you to decide
-on a path forward. Smaller libraries may be copied in whereas very large ones
-may be pulled in with a package manager.
-
-## 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 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.
-
-### The PR / Issue Labels
-Labels make it easier to manage and track PRs / issues.  Below some common labels
-that we use in Solana.  For the complete list of labels, please refer to the
-[label page](https://github.com/solana-labs/solana/issues/labels):
-
-* "feature-gate": when you add a new feature gate or modify the behavior of
-an existing feature gate, please add the "feature-gate" label to your PR.
-New feature gates should also always have a corresponding tracking issue
-(go to "New Issue" -> "Feature Gate Tracker [Get Started](https://github.com/solana-labs/solana/issues/new?assignees=&labels=feature-gate&template=1-feature-gate.yml&title=Feature+Gate%3A+)")
-and should be updated each time the feature is activated on a cluster.
-
-* "automerge": When a PR is labelled with "automerge", the PR will be
-automically merged once CI passes.  In general, this label should only
-be used for small hot-fix (fewer than 100 lines) or automatic generated
-PRs.  If you're uncertain, it's usually the case that the PR is not
-qualified as "automerge".
-
-* "good first issue": If you happen to find an issue that is non-urgent and
-self-contained with moderate scope, you might want to consider attaching
-"good first issue" to it as it might be a good practice for newcomers.
-
-* "rust": this pull request updates Rust code.
-
-* "javascript": this pull request updates Javascript code.

+library, consider developing it in a separate git repository. When it is ready to be
+integrated, the Solana maintainers will work with you to decide on a path forward. Smaller
+libraries may be copied in whereas very large ones may be pulled in with a package manager.
 
 ### When will my PR be reviewed?
 
-PRs are typically reviewed and merged in under 7 days. If your PR has been open
-for longer, it's a strong indicator that the reviewers aren't confident the
-change meets the quality standards of the codebase. You might consider closing
-it and coming back with smaller PRs and longer descriptions detailing what
-problem it solves and how it solves it. Old PRs will be marked stale and then
-closed automatically 7 days later.

-### How to manage review feedback?
-
-After a reviewer provides feedback, you can quickly say "acknowledged, will
-fix" using a thumb's up emoji. If you're confident your fix is exactly as
-prescribed, add a reply "Fixed in COMMIT\_HASH" and mark the comment as
-resolved. If you're not sure, reply "Is this what you had in mind?
-COMMIT\_HASH" and if so, the reviewer will reply and mark the conversation as
-resolved. Marking conversations as resolved is an excellent way to engage more
-reviewers. Leaving conversations open may imply the PR is not yet ready for
-additional review.
-
-### When will my PR be re-reviewed?
-
-Recall that once your PR is opened, a notification is sent every time you push
-a commit.  After a reviewer adds feedback, they won't be checking on the status
-of that feedback after every new commit. Instead, directly mention the reviewer
-when you feel your PR is ready for another pass.

-* For variable names, when in doubt, spell it out. The mapping from type names

-each capital letter. Variable names should *not* be abbreviated unless being

+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.
+
+Architecture
+===
+
+Before you jump into the code, review the online book [Solana: Blockchain Rebuilt for Scale](https://solana-labs.github.io/book/).
+
+(The _latest_ development version of the online book is also [available here](https://solana-labs.github.io/book-edge/).)
+
+Developing
+===
+
+Building
+---
+
+Install rustc, cargo and rustfmt:
 
 ```bash
 $ curl https://sh.rustup.rs -sSf | sh
 $ source $HOME/.cargo/env
-$ rustup component add rustfmt
+$ rustup component add rustfmt-preview
 ```
 
-When building the master branch, please make sure you are using the latest stable rust version by running:
+If your rustc version is lower than 1.34.0, please update it:
 
 ```bash
 $ rustup update
 ```
 
-When building a specific release branch, you should check the rust version in `ci/rust-version.sh` and if necessary, install that version by running:
-```bash
-$ rustup install VERSION
-```
-Note that if this is not the latest rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.
-
 On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, etc.  On Ubuntu:
 
 ```bash
-$ sudo apt-get update
-$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make
+$ sudo apt-get install libssl-dev pkg-config zlib1g-dev llvm clang
 ```
 
-## **2. Download the source code.**

 ```bash
 $ git clone https://github.com/solana-labs/solana.git
 $ cd solana

+* `testnet-edge` - public edge channel testnet accessible via edge.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
+Edit `ci/testnet-manager.sh`
+
+
+## Metrics Server Maintenance
+Sometimes the dashboard becomes unresponsive. This happens due to glitch in the metrics server.
+The current solution is to reset the metrics server. Use the following steps.
+
+1. The server is hosted in a GCP VM instance. Check if the VM instance is down by trying to SSH
+ into it from the GCP console. The name of the VM is ```metrics-solana-com```.
+2. If the VM is inaccessible, reset it from the GCP console.
+3. Once VM is up (or, was already up), the metrics services can be restarted from build automation.
+    1. Navigate to https://buildkite.com/solana-labs/metrics-dot-solana-dot-com in your web browser
+    2. Click on ```New Build```
+    3. This will show a pop up dialog. Click on ```options``` drop down.
+    4. Type in ```FORCE_START=true``` in ```Environment Variables``` text box.
+    5. Click ```Create Build```
+    6. This will restart the metrics services, and the dashboards should be accessible afterwards.
+
+## Debugging Testnet
+Testnet may exhibit different symptoms of failures. Primary statistics to check are
+1. Rise in Confirmation Time
+2. Nodes are not voting
+3. Panics, and OOM notifications
+
+Check the following if there are any signs of failure.
+1. Did testnet deployment fail?
+    1. View buildkite logs for the last deployment: https://buildkite.com/solana-labs/testnet-management
+    2. Use the relevant branch
+    3. If the deployment failed, look at the build logs. The build artifacts for each remote node is uploaded.
+       It's a good first step to triage from these logs.
+2. You may have to log into remote node if the deployment succeeded, but something failed during runtime.
+    1. Get the private key for the testnet deployment from ```metrics-solana-com``` GCP instance.
+    2. SSH into ```metrics-solana-com``` using GCP console and do the following.
+    ```bash
+    sudo bash
+    cd ~buildkite-agent/.ssh
+    ls
+    ```
+    3. Copy the relevant private key to your local machine
+    4. Find the public IP address of the AWS instance for the remote node using AWS console
+    5. ```ssh -i <private key file> ubuntu@<ip address of remote node>```
+    6. The logs are in ```~solana\solana``` folder

+#### Create the new branch
+1. Pick your branch point for release on master.
+1. Create the branch.  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".
-1. Create the new branch and push this branch to the `solana` repository:
-    ```
-    git checkout -b <branchname>
-    git push -u origin <branchname>
-    ```
+    1.  Note the Cargo.toml in the repo root directory does not contain a version.  Look at any other Cargo.toml file.
+1. Create a new branch and push this branch to the solana repository.
+    1. `git checkout -b <branchname>`
+    1. `git push -u origin <branchname>`
 
-Alternatively use the Github UI.
+#### Update master with the next version
 
-### Update master branch to the next release minor version
+1. After the new branch has been created and pushed, update Cargo.toml on **master** to the next semantic version (e.g. 0.9.0 -> 0.10.0)
+   by running `./scripts/increment-cargo-version.sh`, then rebuild with
+   `cargo build` to cause a refresh of `Cargo.lock`.
+1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
+   master branch
 
-1. After the new branch has been created and pushed, update the Cargo.toml files on **master** to the next semantic version (e.g. 0.9.0 -> 0.10.0) with:
-     ```
-     $ scripts/increment-cargo-version.sh minor
-     $ ./scripts/cargo-for-all-lock-files.sh update

-## Steps to Create a Release
+### Updating channels (i.e. "making a release")
 
-### Create the Release Tag on GitHub
+We use [github's Releases UI](https://github.com/solana-labs/solana/releases) for tagging a release.
 
-1. Go to [GitHub Releases](https://github.com/solana-labs/solana/releases) for tagging a release.
+1. Go [there ;)](https://github.com/solana-labs/solana/releases).
 1. Click "Draft new release".  The release tag must exactly match the `version`
-   field in `/Cargo.toml` prefixed by `v`.
-   1.  If the Cargo.toml version field is **0.12.3**, then the release tag must be **v0.12.3**
-1. Make sure the Target Branch field matches the branch you want to make a release on.
-   1.  If you want to release v0.12.0, the target branch must be v0.12
-1. Fill the release notes.
+   field in `/Cargo.toml` prefixed by `v` (ie, `<branchname>.X`).
+   1.  If the Cargo.toml verion field is **0.12.3**, then the release tag must be **v0.12.3**
 1. If this is the first release on the branch (e.g. v0.13.**0**), paste in [this
-   template](https://raw.githubusercontent.com/solana-labs/solana/master/.github/RELEASE_TEMPLATE.md).  Engineering Lead can provide summary contents for release notes if needed.
-   1. If this is a patch release, review all the commits since the previous release on this branch and add details as needed.
-1. Click "Save Draft", then confirm the release notes look good and the tag name and branch are correct.
-1. Ensure all desired commits (usually backports) are landed on the branch by now.
-1. Ensure the release is marked **"This is a pre-release"**.  This flag will need to be be removed manually after confirming the the Linux binary artifacts appear at a later step.
-1. Go back into edit the release and click "Publish release" while being marked as a pre-release.
-1. Confirm there is new git tag with intended version number at the intended revision after running `git fetch` locally.
-
-
-### Update release branch with the next patch version
-
-1. After the new release has been tagged, update the Cargo.toml files on **release branch** to the next semantic version (e.g. 0.9.0 -> 0.9.1) with:
-     ```
-     $ scripts/increment-cargo-version.sh patch
-     $ ./scripts/cargo-for-all-lock-files.sh tree
-     ```
-1. Push all the changed Cargo.toml and Cargo.lock files to the **release branch** with something like:
-    ```
-    git co -b version_update origin/vX.Y
-    git add -u
-    git commit -m 'Bump version to X.Y.Z+1'
-    git push -u <user-remote> version_update
-    ```
-1. Open a PR against origin/vX.Y and then merge the PR after passing CI.
-
-### Prepare for the next release
-1.  Go to [GitHub Releases](https://github.com/solana-labs/solana/releases) and create a new draft release for `X.Y.Z+1` with empty release notes.  This allows people to incrementally add new release notes until it's time for the next release
-    1. Also, point the branch field to the same branch and mark the relese as **"This is a pre-release"**.
-1.  Go to the [Github Milestones](https://github.com/solana-labs/solana/milestones).  Create a new milestone for the `X.Y.Z+1`, move over
-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
-
-### Update software on testnet.solana.com
-See the documentation at https://github.com/solana-labs/cluster-ops/. devnet.solana.com and mainnet-beta.solana.com run stable releases that have been tested on testnet. Do not update devnet or mainnet-beta with a beta release.
+   template](https://raw.githubusercontent.com/solana-labs/solana/master/.github/RELEASE_TEMPLATE.md)
+   and fill it in.
+1. Test the release by generating a tag using semver's rules.  First try at a
+   release should be `<branchname>.X-rc.0`.
+1. Verify release automation:
+   1. [Crates.io](https://crates.io/crates/solana) should have an updated Solana version.
+   1. ...
+1. After testnet deployment, verify that testnets are running correct software.
+   http://metrics.solana.com should show testnet running on a hash from your
+   newly created branch.
+1. Once the release has been made, update Cargo.toml on the release branch to the next
+   semantic version (e.g. 0.9.0 -> 0.9.1) by running
+   `./scripts/increment-cargo-version.sh patch`, then rebuild with `cargo
+   build` to cause a refresh of `Cargo.lock`.
+1. Push your Cargo.toml change and the autogenerated Cargo.lock changes to the
+   release branch.

-## Reporting security problems to Solana
-
-**DO NOT CREATE AN ISSUE** to report a security problem. Instead, please send an
-email to security@solana.com and provide your github username so we can add you
-to a new draft security advisory for further discussion.
-
-Expect a response as fast as possible, typically within 72 hours.
-
-<a name="bounty"></a>
-## Security Bug Bounties
-We offer bounties for critical security issues. Please see below for more details.
-
-Loss of Funds:
-$2,000,000 USD in locked SOL tokens (locked for 12 months)
-* Theft of funds without users signature from any account
-* Theft of funds without users interaction in system, token, stake, vote programs
-* Theft of funds that requires users signature - creating a vote program that drains the delegated stakes.
-
-Consensus/Safety Violations:
-$1,000,000 USD in locked SOL tokens (locked for 12 months)
-* Consensus safety violation
-* Tricking a validator to accept an optimistic confirmation or rooted slot without a double vote, etc..
-
-Other Attacks:
- $400,000 USD in locked SOL tokens (locked for 12 months)
-* Protocol liveness attacks,
-* Eclipse attacks,
-* Remote attacks that partition the network,
-
-DoS Attacks:
-$100,000 USD in locked SOL tokens (locked for 12 months)
-* Remote resource exaustion via Non-RPC protocols
-
-RPC DoS/Crashes:
-$5,000 USD in locked SOL tokens (locked for 12 months)
-* RPC attacks
-
-Out of Scope:
-The following components are out of scope for the bounty program
-* Metrics: `/metrics` in the monorepo as well as https://metrics.solana.com
-* Explorer: `/explorer` in the monorepo as well as https://explorer.solana.com
-* Any encrypted credentials, auth tokens, etc. checked into the repo
-* Bugs in dependencies. Please take them upstream!
-* Attacks that require social engineering
-
-Eligibility:
-* The participant submitting the bug report shall follow the process outlined within this document
-* Valid exploits can be eligible even if they are not successfully executed on the cluster
-* Multiple submissions for the same class of exploit are still eligible for compensation, though may be compensated at a lower rate, however these will be assessed on a case-by-case basis
-* Participants must complete KYC and sign the participation agreement here when the registrations are open https://solana.com/validator-registration. Security exploits will still be assessed and open for submission at all times. This needs only be done prior to distribution of tokens.
-
-Payment of Bug Bounties:
-* Payments for eligible bug reports are distributed monthly.
-* Bounties for all bug reports submitted in a given month are paid out in the middle of the
-following month.
-* The SOL/USD conversion rate used for payments is the market price at the end of
-  the last day of the month for the month in which the bug was submitted.
-* The reference for this price is the Closing Price given by Coingecko.com on
-  that date given here:
-  https://www.coingecko.com/en/coins/solana/historical_data/usd#panel
-* For example, for all bugs submitted in March 2021, the SOL/USD price for bug
-  payouts is the Close price on 2021-03-31 of $19.49.  This applies to all bugs
-  submitted in March 2021, to be paid in mid-April 2021.
-* Bug bounties are paid out in
-[stake accounts](https://solana.com/staking) with a
-[lockup](https://docs.solana.com/staking/stake-accounts#lockups)
-expiring 12 months from the last day of the month in which the bug was submitted.

-<a name="process"></a>
-## Incident Response Process
-
-In case an incident is discovered or reported, the following process will be
-followed to contain, respond and remediate:
-
-### 1. Establish a new draft security advisory
-In response to an email to security@solana.com, a member of the `solana-labs/admins` group will
-1. Create a new draft security advisory for the incident at https://github.com/solana-labs/solana/security/advisories
-1. Add the reporter's github user and the `solana-labs/security-incident-response` group to the draft security advisory
-1. Create a private fork of the repository (grey button towards the bottom of the page)
-1. Respond to the reporter by email, sharing a link to the draft security advisory
-
-### 2. Triage
-Within the draft security advisory, discuss and determine the severity of the
-issue. If necessary, members of the `solana-labs/security-incident-response`
-group may add other github users to the advisory to assist.
-
-If it is determined that this not a critical network issue then the advisory
-should be closed and if more follow-up is required a normal Solana public github
-issue should be created.
-
-### 3. Prepare Fixes
-For the affected branches, typically all three (edge, beta and stable), prepare
-a fix for the issue and push them to the corresponding branch in the private
-repository associated with the draft security advisory.
-
-There is no CI available in the private repository so you must build from source
-and manually verify fixes.
-
-Code review from the reporter is ideal, as well as from multiple members of the
-core development team.
-
-### 4. Notify Security Group Validators
-Once an ETA is available for the fix, a member of the
-`solana-labs/security-incident-response` group should notify the validators so
-they can prepare for an update using the "Solana Red Alert" notification system.
-
-The teams are all over the world and it's critical to provide actionable
-information at the right time. Don't be the person that wakes everybody up at
-2am when a fix won't be available for hours.
-
-### 5. Ship the patch
-Once the fix is accepted, a member of the
-`solana-labs/security-incident-response` group should prepare a single patch
-file for each affected branch. The commit title for the patch should only
-contain the advisory id, and not disclose any further details about the
-incident.
-
-Copy the patches to https://release.solana.com/ under a subdirectory named after
-the advisory id (example:
-https://release.solana.com/GHSA-hx59-f5g4-jghh/v1.4.patch). Contact a member of
-the `solana-labs/admins` group if you require access to release.solana.com
-
-Using the "Solana Red Alert" channel:
-1. Notify validators that there's an issue and a patch will be provided in X minutes
-2. If X minutes expires and there's no patch, notify of the delay and provide a
-   new ETA
-3. Provide links to patches of https://release.solana.com/ for each affected branch
-
-Validators can be expected to build the patch from source against the latest
-release for the affected branch.
-
-Since the software version will not change after the patch is applied, request
-that each validator notify in the existing channel once they've updated. Manually
-monitor the roll out until a sufficient amount of stake has updated - typically
-at least 33.3% or 66.6% depending on the issue.
-
-### 6. Public Disclosure and Release
-Once the fix has been deployed to the security group validators, the patches from the security
-advisory may be merged into the main source repository. A new official release
-for each affected branch should be shipped and all validators requested to
-upgrade as quickly as possible.
-
-### 7. Security Advisory Bounty Accounting and Cleanup
-
-If this issue is eligible for a bounty, prefix the title of the security
-advisory with one of the following, depending on the severity:
-* `[Bounty Category: Critical: Loss of Funds]`
-* `[Bounty Category: Critical: Loss of Availability]`
-* `[Bounty Category: Critical: DoS]`
-* `[Bounty Category: Critical: Other]`
-* `[Bounty Category: Non-critical]`
-* `[Bounty Category: RPC]`
-
-Confirm with the reporter that they agree with the severity assessment, and
-discuss as required to reach a conclusion.
-
-We currently do not use the Github workflow to publish security advisories.
-Once the issue and fix have been disclosed, and a bounty category is assessed if
-appropriate, the GitHub security advisory is no longer needed and can be closed.
-
-Bounties are currently awarded once a quarter (TODO: link to this process, or
-inline the workflow)

+## 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 trade requests to
+the exchange.  A broker monitors the exchange and posts swap requests for
+matching trade 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.
+- Token pair
+  - A unique ordered list of two tokens.  For the four types of tokens used in
+    this demo, the valid pairs are AB, AC, AD, BC, BD, CD.
+- Direction of trade
+  - Describes which token in the pair the investor wants to sell and buy and can
+    be either "To" or "From".  For example, if an investor issues a "To" trade
+    for "AB" then they which to exchange A tokens to B tokens.  A "From" order
+    would read the other way,  A tokens from B tokens.
+- Price ratio
+  -  An expression of the relative prices of two tokens.  They consist of the
+     price of the primary token and the price of the secondary token.  For
+     simplicity sake, the primary token's price is always 1, which forces the
+     secondary to be the common denominator.  For example, if token A was worth
+     2 and token B was worth 6, the price ratio would be 1:3 or just 3.  Price
+     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)
+- Trade request
+  - A Solana transaction executed by the exchange requesting the trade of one
+    type of token for another.  Trade requests are made up of the token pair,
+    the direction of the trade, 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 trade requests result in a trade order.
+- Trade order
+  - The result of a successful trade request.  Trade orders are stored in
+    accounts owned by the submitter of the trade 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 trade request.
+- Price spread
+  - The difference between the two matching trade orders. The spread is the
+    profit of the broker initiating the swap request.
+- Swap requirements
+  - Policies that result in a successful trade swap.
+- Swap request
+  - A request to exchange tokens between to trade orders
+- Trade swap
+  - A successful trade.  A swap consists of two matching trade orders that meet
+    swap requirements.  A trade swap may not wholly satisfy one or both of the
+    trade orders in which case the trade orders are adjusted appropriately.  As
+    long as the swap requirements are met there will be an exchange of tokens
+    between accounts.  Any price spread is deposited into the broker's profit
+    account.  All trade swaps are recorded in a new 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 trade requests.  Investors post
+    transactions to the exchange in order to request tokens and post or cancel
+    trade requests.
+- Broker
+  - An agent who facilitates trading between investors.  Brokers operate as
+    Solana thin clients who monitor all the trade orders looking for a trade
+    match.  Once found, the broker issues a swap request to the exchange.
+    Brokers are the engine of the exchange and are rewarded for their efforts by
+    accumulating the price spreads of the swaps they initiate.  Brokers 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 Brokers.
+
+## Exchange startup
+
+The exchange is up and running when it reaches a state where it can take
+investor's trades and broker's swap requests.  To achieve this state the
+following must occur in order:
+
+- Start the Solana blockchain
+- Start the broker thin-client
+- The broker 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 broker starts responding to queries for bid/ask price and OHLCV
+
+The broker 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 broker could come and go without missing a trade.  One way to achieve
+this is for the broker to read the current state of all accounts looking for all
+open trade 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.  Brokers 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 brokers 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),
+}
+```
+
+## Trade requests
+
+When an investor decides to exchange a token of one type for another, they
+submit a transaction to the Solana Blockchain containing a trade request, which,
+if successful, is turned into a trade order.  Trade orders do not expire but are
+cancellable. <!-- Trade orders should have a timestamp to enable trade
+expiration -->  When a trade order is created, tokens are deducted from a token
+account and the trade order acts as an escrow.  The tokens are held until the
+trade 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.  Trade 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 trade orders, so trade 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 TradeRequestInfo {
+    /// 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 {
+    /// Trade 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 trade 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,
+}
+```
+
+## Trade 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 {
+    /// Trade cancellation
+    /// key 0 - Signer
+    /// key 1 -Trade order to cancel
+    TradeCancellation,
+}
+```
+
+## Trade swaps
+
+The broker is monitoring the accounts assigned to the exchange program and
+building a trade-order table.  The trade order table is used to identify
+matching trade orders which could be fulfilled.  When a match is found the
+broker 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 trade order valid for further swap requests in
+the future.
+
+Matching trade 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
+broker's account equal to the difference in the price ratios or the two orders.
+These tokens are considered the broker's profit for initiating the trade.
+
+The broker 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
+  - Broker 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 broker 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
+  - Broker 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 broker 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
+  - Broker 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 broker 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
+  - Broker takes 4 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' trade order
+    /// key 3 - `From` trade 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 brokers profit from the swap.
+    SwapRequest,
+}
+
+/// Swap accounts are populated with this structure
+pub struct TradeSwapInfo {
+    /// Pair swapped
+    pub pair: TokenPair,
+    /// `To` trade order
+    pub to_trade_order: Pubkey,
+    /// `From` trade order
+    pub from_trade_order: Pubkey,

+    /// 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),
+
+    /// Trade request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - Token account associated with this trade
+    TradeRequest(TradeRequestInfo),
+
+    /// Trade cancellation
+    /// key 0 - Signer
+    /// key 1 -Trade order to cancel
+    TradeCancellation,
+
+    /// Trade swap request
+    /// key 0 - Signer
+    /// key 1 - Account in which to record the swap
+    /// key 2 - 'To' trade order
+    /// key 3 - `From` trade 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 brokers profit from the swap.
+    SwapRequest,
+}
+```
+
+## Quotes and OHLCV
+
+The broker 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
+```
