+Solana Coding Guidelines
+===
+
+The goal of these guidelines is to improve developer productivity by allowing developers to
+jump any file in the codebase and not need to adapt to inconsistencies in how the code is
+written. The codebase should appear as if it had been authored by a single developer. If you
+don't agree with a convention, submit a PR patching this document and let's discuss! Once
+the PR is accepted, *all* code should be updated as soon as possible to reflect the new
+conventions.
+
+Rust coding conventions
+---
+
+* All Rust code is formatted using the latest version of `rustfmt`. Once installed, it will be
+  updated automatically when you update the compiler with `rustup`.
+
+* All Rust code is linted with Clippy. If you'd prefer to ignore its advice, do so explicitly:
+
+  ```rust
+  #[cfg_attr(feature = "cargo-clippy", allow(too_many_arguments))]
+  ```
+
+  Note: Clippy defaults can be overridden in the top-level file `.clippy.toml`.
+
+* For variable names, when in doubt, spell it out. The mapping from type names to variable names
+  is to lowercase the type name, putting an underscore before each capital letter. Variable names
+  should *not* be abbreviated unless being used as closure arguments and the brevity improves
+  readability. When a function has multiple instances of the same type, qualify each with a
+  prefix and underscore (i.e. alice_keypair) or a numeric suffix (i.e. tx0).
+
+* For function and method names, use `<verb>_<subject>`. For unit tests, that verb should
+  always be `test` and for benchmarks the verb should always be `bench`. Avoid namespacing
+  function names with some arbitrary word. Avoid abreviating words in function names.
+
+* As they say, "When in Rome, do as the Romans do." A good patch should acknowledge the coding
+  conventions of the code that surrounds it, even in the case where that code has not yet been
+  updated to meet the conventions described here.
+
+
+Terminology
+---
+
+Inventing new terms is allowed, but should only be done when the term is widely used and
+understood. Avoid introducing new 3-letter terms, which can be confused with 3-letter acronyms.
+
+Some terms we currently use regularly in the codebase:
+
+* fullnode: n. A fully participating network node.
+* hash: n. A SHA-256 Hash.
+* keypair: n. A Ed25519 key-pair, containing a public and private key.
+* pubkey: n. The public key of a Ed25519 key-pair.
+* sigverify: v. To verify a Ed25519 digital signature.
+

 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)]. 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! Furthermore, and much to our surprise, it can 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 in route towards that theoretical limit of 710,000 transactions per second.

+
+> 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)

+This image may be manually updated by running `CI=true ./build.sh` if you are a member
 of the [Solana Labs](https://hub.docker.com/u/solanalabs/) Docker Hub
 organization, but it is also automatically updated periodically by
 [this automation](https://buildkite.com/solana-labs/solana-ci-docker-rust-nightly).
+
+## Moving to a newer nightly
+
+We pin the version of nightly (see the `ARG nightly=xyz` line in `Dockerfile`)
+to avoid the build breaking at unexpected times, as occasionally nightly will
+introduce breaking changes.
+
+To update the pinned version:
+1. Run `ci/docker-rust-nightly/build.sh` to rebuild the nightly image locally,
+   or potentially `ci/docker-rust-nightly/build.sh YYYY-MM-DD` if there's a
+   specific YYYY-MM-DD that is desired (default is today's build).
+1. Run `SOLANA_DOCKER_RUN_NOSETUID=1 ci/docker-run.sh --nopull solanalabs/rust-nightly:YYYY-MM-DD ci/test-nightly.sh`
+   to confirm the new nightly image builds.  Fix any issues as needed
+1. Run `docker login` to enable pushing images to Docker Hub, if you're authorized.
+1. Run `CI=true ci/docker-rust-nightly/build.sh YYYY-MM-DD` to push the new nightly image to dockerhub.com.
+1. Modify the `solanalabs/rust-nightly:YYYY-MM-DD` reference in `ci/buildkite.yml` from the previous to
+   new *YYYY-MM-DD* value, send a PR with this change and any codebase adjustments needed.
+
+## Troubleshooting
+
+### Resource is denied
+
+When running `CI=true ci/docker-rust-nightly/build.sh`, you see:
+
+```
+denied: requested access to the resource is denied
+```
+
+Run `docker login` to enable pushing images to Docker Hub. Contact @mvines or @garious
+to get write access.

+semver_bash is a bash parser for semantic versioning
+====================================================
+
+[Semantic Versioning](http://semver.org/) is a set of guidelines that help keep
+version and version management sane. This is a bash based parser to help manage
+a project's versions. Use it from a Makefile or any scripts you use in your
+project.
+
+Usage
+-----
+semver_bash can be used from the command line as:  
+
+    $ ./semver.sh "3.2.1" "3.2.1-alpha"  
+    3.2.1 -> M: 3 m:2 p:1 s:  
+    3.2.1-alpha -> M: 3 m:2 p:1 s:-alpha  
+    3.2.1 == 3.2.1-alpha -> 1.  
+    3.2.1 < 3.2.1-alpha -> 1.  
+    3.2.1 > 3.2.1-alpha -> 0.
+
+
+Alternatively, you can source it from within a script:
+
+    . ./semver.sh  
+    
+    local MAJOR=0  
+    local MINOR=0  
+    local PATCH=0

+Solana JSON RPC API
+===
+
+Solana nodes accept HTTP requests using the [JSON-RPC 2.0](https://www.jsonrpc.org/specification) specification.
+
+To interact with a Solana node inside a JavaScript application, use the [solana-web3.js](https://github.com/solana-labs/solana-web3.js) library, which gives a convenient interface for the RPC methods.
+
+RPC Endpoint
+---
+
+**Default port:** 8899  
+eg. http://localhost:8899, http://192.168.1.88:8899
+
+Methods
+---
+
+* [confirmTransaction](#confirmtransaction)
+* [getAddress](#getaddress)
+* [getBalance](#getbalance)
+* [getLastId](#getlastid)
+* [getTransactionCount](#gettransactioncount)
+* [requestAirdrop](#requestairdrop)
+* [sendTransaction](#sendtransaction)
+
+Request Formatting
+---
+
+To make a JSON-RPC request, send an HTTP POST request with a `Content-Type: application/json` header. The JSON request data should contain 4 fields:
+
+* `jsonrpc`, set to `"2.0"`
+* `id`, a unique client-generated identifying integer
+* `method`, a string containing the method to be invoked
+* `params`, a JSON array of ordered parameter values
+
+Example using curl:
+```bash
+curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0", "id":1, "method":"getBalance", "params":["83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri"]}' 192.168.1.88:8899
+```
+
+The response output will be a JSON object with the following fields:
+
+* `jsonrpc`, matching the request specification
+* `id`, matching the request identifier
+* `result`, requested data or success confirmation
+
+Requests can be sent in batches by sending an array of JSON-RPC request objects as the data for a single POST.
+
+Definitions
+---
+
+* Hash: A SHA-256 hash of a chunk of data.
+* Pubkey: The public key of a Ed25519 key-pair.
+* Signature: An Ed25519 signature of a chunk of data.
+* Transaction: A Solana instruction signed by a client key-pair.
+
+JSON RPC API Reference
+---

+# TestNet debugging info
+
+Currently we have two testnets, 'perf' and 'master', both on the master branch of the solana repo. Deploys happen
+at the top of every hour with the latest code. 'perf' has more cores for the client machine to flood the network
+with transactions until failure.
+
+## Deploy process
+
+They are deployed with the `ci/testnet-deploy.sh` script. There is a scheduled buildkite job which runs to do the deploy,
+look at `testnet-deploy` to see the agent which ran it and the logs. There is also a manual job to do the deploy manually..
+Validators are selected based on their machine name and everyone gets the binaries installed from snap.
+
+## Where are the testnet logs?
+
+For the client they are put in `/tmp/solana`; for validators and leaders they are in `/var/snap/solana/current/`.
+You can also see the backtrace of the client by ssh'ing into the client node and doing:
+
+```bash
+$ sudo -u testnet-deploy
+$ tmux attach -t solana
+```
+
+## How do I reset the testnet?
+
+Through buildkite.
+
+## 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.
+
+## Adjusting the number of clients or validators on the testnet
+
+1. Go to the [GCP Instance Group](https://console.cloud.google.com/compute/instanceGroups/list?project=principal-lane-200702) tab
+2. Find the client or validator instance group you'd like to adjust
+3. Edit it (pencil icon), change the "Number of instances", then click "Save" button
+4. Refresh until the change to number of instances has been executed
+5. Click the "New Build" button on the [testnet-deploy](https://buildkite.com/solana-labs/testnet-deploy/)
+   buildkite job to initiate a redeploy of the network with the updated instance count.

+# Network Management
+This directory contains scripts useful for working with a test network.  It's
+intended to be both dev and CD friendly.
+
+### User Account Prerequisites
+
+Log in to GCP with:
+```bash
+$ gcloud auth login
+```
+
+Also ensure that `$(whoami)` is the name of an InfluxDB user account with enough
+access to create a new database.
+
+## Quick Start
+```bash
+$ cd net/
+$ ./gce.sh create -n 5 -c 1  #<-- Create a GCE testnet with 5 validators, 1 client (billing starts here)
+$ ./init-metrics.sh $(whoami)   #<-- Configure a metrics database for the testnet
+$ ./net.sh start             #<-- Deploy the network from the local workspace
+$ ./ssh.sh                   #<-- Details on how to ssh into any testnet node
+$ ./gce.sh delete            #<-- Dispose of the network (billing stops here)
+```
+
+## Tips
+
+### Running the network over public IP addresses
+By default private IP addresses are used with all instances in the same
+availability zone to avoid GCE network engress charges.  However to run the
+network over public IP addresses:
+```bash
+$ ./gce.sh create -P ...
+```
+
+### Deploying a Snap-based network
+To deploy the latest pre-built `edge` channel Snap (ie, latest from the `master`
+branch), once the testnet has been created run:
+
+```bash
+$ ./net.sh start -s edge
+```
+
+### Enabling CUDA
+First ensure the network instances are created with GPU enabled:
+```bash
+$ ./gce.sh create -g ...
+```
+
+If deploying a Snap-based network nothing further is required, as GPU presence
+is detected at runtime and the CUDA build is auto selected.
+
+If deploying a locally-built network, first run `./fetch-perf-libs.sh` then
+ensure the `cuda` feature is specified at network start:
+```bash
+$ ./net.sh start -f "cuda,erasure"
+```
+
+### How to interact with a CD testnet deployed by ci/testnet-deploy.sh
+
+Taking **master-testnet-solana-com** as an example, configure your workspace for
+the testnet using:
+```
+$ ./gce.sh config -p master-testnet-solana-com
+$ ./ssh.sh                                     # <-- Details on how to ssh into any testnet node
+```

 In Figure 1 an untrusted client, creates a program in the front-end language of her choice, (like C/C++/Rust/Lua), and compiles it with LLVM to a position independent shared object ELF, targeting BPF bytecode. Solana will safely load and execute the ELF.
 
-## Bytecode
-
-Our bytecode is based on Berkley Packet Filter. The requirements for BPF overlap almost exactly with the requirements we have:
-
-1. Deterministic amount of time to execute the code
-2. Bytecode that is portable between machine instruction sets
-3. Verified memory accesses
-4. Fast to load the object, verify the bytecode and JIT to local machine instruction set
-
-For 1, that means that loops are unrolled, and for any jumps back we can guard them with a check against the number of instruction that have been executed at this point.  If the limit is reached, the program yields its execution.  This involves saving the stack and current instruction index.
-
-For 2, the BPF bytecode already easily maps to x86–64, arm64 and other instruction sets. 
-
-For 3, every load and store that is relative can be checked to be within the expected memory that is passed into the ELF.  Dynamic load and stores can do a runtime check against available memory, these will be slow and should be avoided.
-
-For 4, Fully linked PIC ELF with just a single RX segment. Effectively we are linking a shared object with `-fpic -target bpf` and with a linker script to collect everything into a single RX segment. Writable globals are not supported.
-
-### Address Checks
-
-The interface to the module takes a `&mut Vec<Vec<u8>>` in rust, or a `int sz, void* data[sz], int szs[sz]` in `C`.  Given the module's bytecode, for each method, we need to analyze the bounds on load and stores into each buffer the module uses.  This check needs to be done `on chain`, and after those bounds are computed we can verify that the user supplied array of buffers will not cause a memory fault.  For load and stores that we cannot analyze, we can replace with a `safe_load` and `safe_store` instruction that will check the table for access.
-
-## Loader
-The loader is our first smart contract. The job of this contract is to load the actual program with its own instance data.  The loader will verify the bytecode and that the object implements the expected entry points.
-
-Since there is only one RX segment, the context for the contract instance is passed into each entry point as well as the event data for that entry point.
-
-A client will create a transaction to create a new loader instance:
-
-`Solana_NewLoader(Loader Instance PubKey, proof of key ownership, space I need for my elf)`
-
-A client will then do a bunch of transactions to load its elf into the loader instance they created:
-
-`Loader_UploadElf(Loader Instance PubKey, proof of key ownership, pos start, pos end, data)`
-
-At this point the client can create a new instance of the module with its own instance address:
-
-`Loader_NewInstance(Loader Instance PubKey, proof of key ownership, Instance PubKey, proof of key ownership)`
-
-Once the instance has been created, the client may need to upload more user data to solana to configure this instance:
-
-`Instance_UploadModuleData(Instance PubKey, proof of key ownership, pos start, pos end, data)`
-
-Now clients can `start` the instance:
-
-`Instance_Start(Instance PubKey, proof of key ownership)`
-
 ## Runtime
 
-Our goal with the runtime is to have a general purpose execution environment that is highly parallelizable and doesn't require dynamic resource management. We want to execute as many contracts as we can in parallel, and have them pass or fail without a destructive state change.
+The goal with the runtime is to have a general purpose execution environment that is highly parallelizeable and doesn't require dynamic resource management. The goal is to execute as many contracts as possible in parallel, and have them pass or fail without a destructive state change.
-
-### State and Entry Point
-
-State is addressed by an account which is at the moment simply the PubKey.  Our goal is to eliminate dynamic memory allocation in the smart contract itself, so the contract is a function that takes a mapping of [(PubKey,State)] and returns [(PubKey, State')].  The output of keys is a subset of the input.  Three basic kinds of state exist:
-
-* Instance State
-* Participant State
-* Caller State
-
-There isn't any difference in how each is implemented, but conceptually Participant State is memory that is allocated for each participant in the contract.  Instance State is memory that is allocated for the contract itself, and Caller State is memory that the transactions caller has allocated.
 
 
-### Call
+### State
 
+State is addressed by an account which is at the moment simply the Pubkey.  Our goal is to eliminate memory allocation from within the smart contract itself.  Thus the client of the contract provides all the state that is necessary for the contract to execute in the transaction itself.  The runtime interacts with the contract through a state transition function, which takes a mapping of [(Pubkey,State)] and returns [(Pubkey, State')].  The State is an opeque type to the runtime, a `Vec<u8>`, the contents of which the contract has full control over.
+
+### Call Structure
 ```
-void call(
+/// Call definition
-    const struct instance_data *data,
+/// Signed portion
-    const uint8_t kind[],  //instance|participant|caller|read|write
+#[derive(Serialize, Deserialize, Debug, PartialEq, Eq, Clone)]
-    const uint8_t *keys[],
+pub struct CallData {
-    uint8_t *data[],
+    /// Each Pubkey in this vector is mapped to a corresponding `Page` that is loaded for contract execution
-    int num,
+    /// In a simple pay transaction `key[0]` is the token owner's key and `key[1]` is the recipient's key.
-    uint8_t dirty[],        //dirty memory bits
+    pub keys: Vec<Pubkey>,
-    uint8_t *userdata,      //current transaction data
+
-);
+    /// The Pubkeys that are required to have a proof.  The proofs are a `Vec<Signature> which encoded along side this data structure
+    /// Each Signature signs the `required_proofs` vector as well as the `keys` vectors.  The transaction is valid if and only if all
+    /// the required signatures are present and the public key vector is unchanged between signatures.
+    pub required_proofs: Vec<u8>,
+
+    /// PoH data
+    /// last PoH hash observed by the sender
+    pub last_id: Hash,
+
+    /// Program
+    /// The address of the program we want to call.  ContractId is just a Pubkey that is the address of the loaded code that will execute this Call.
+    pub contract_id: ContractId,
+    /// OS scheduling fee
+    pub fee: i64,
+    /// struct version to prevent duplicate spends
+    /// Calls with a version <= Page.version are rejected
+    pub version: u64,
+    /// method to call in the contract
+    pub method: u8,
+    /// usedata in bytes
+    pub userdata: Vec<u8>,
+}
+
+#[derive(Serialize, Deserialize, Debug, PartialEq, Eq, Clone)]
+pub struct Call {
+    /// Signatures and Keys
+    /// (signature, key index)
+    /// This vector contains a tuple of signatures, and the key index the signature is for
+    /// proofs[0] is always key[0]
+    pub proofs: Vec<Signature>,
+    pub data: CallData,
+}
 ```
 
-To call this operation, the transaction that is destined to the contract instance specifies what keyed state it should present to the `call` function.  To allocate the state memory or a call context, the client has to first call a function on the contract with the designed address that will own the state.
+At it's core, this is just a set of Pubkeys and Signatures with a bit of metadata.  The contract Pubkey routes this transaction into that contracts entry point.  `version` is used for dropping retransmitted requests.
 
-At its core, this is a system call that requires cryptographic proof of ownership of memory regions instead of an OS that checks page tables for access rights.
+Contracts should be able to read any state that is part of runtime, but only write to state that the contract allocated.
-
-* `Instance_AllocateContext(Instance PubKey, My PubKey, Proof of key ownership)`
-
-Any transaction can then call `call` on the contract with a set of keys.  It's up to the contract itself to manage ownership:
-
-* `Instance_Call(Instance PubKey, [Context PubKeys], proofs of ownership, userdata...)`
-
-Contracts should be able to read any state that is part of solana, but only write to state that the contract allocated.
-
-#### Caller State
-
-Caller `state` is memory allocated for the `call` that belongs to the public key that is issuing the `call`.  This is the caller's context.
-
-#### Instance State
-
-Instance `state` is memory that belongs to this contract instance.  We may also need module-wide `state` as well.
-
-#### Participant State
-
-Participant `state` is any other memory.  In some cases it may make sense to have these allocated as part of the call by the caller.
-
-### Reduce
-
-Some operations on the contract will require iteration over all the keys.  To make this parallelizable the iteration is broken up into reduce calls which are combined.
-
-```
-void reduce_m(
-    const struct instance_data *data,
-    const uint8_t *keys[],
-    const uint8_t *data[],
-    int num,
-    uint8_t *reduce_data,
-);
-
-void reduce_r(
-    const struct instance_data *data,
-    const uint8_t *reduce_data[],
-    int num,
-    uint8_t *reduce_data,
-);
-```
 
 ### Execution
 
-Transactions are batched and processed in parallel at each stage.

-
 
 ```
-The `debit verify` stage is very similar to `memory verify`.  Proof of key ownership is used to check if the callers key has some state allocated with the contract, then the memory is loaded and executed.  After execution stage, the dirty pages are written back by the contract.  Because know all the memory accesses during execution, we can batch transactions that do not interfere with each other.  We can also apply the `debit undo` and `credit commit` stages of the transaction.  `debit undo` is run in case of an exception during contract execution, only transfers may be reversed, fees are commited to solana.

-### GPU execution
+```
 
-A single contract can read and write to separate key pairs without interference.  These separate calls to the same contract can execute on the same GPU thread over different memory using different SIMD lanes.
+At the `execute` stage, the loaded pages have no data dependencies, so all the contracts can be executed in parallel. 
+## Memory Management
+```
+pub struct Page {
+    /// key that indexes this page
+    /// prove ownership of this key to spend from this Page
+    owner: Pubkey,
+    /// contract that owns this page
+    /// contract can write to the data that is in `memory` vector
+    contract: Pubkey,
+    /// balance that belongs to owner
+    balance: u64,
+    /// version of the structure, public for testing
+    version: u64,
+    /// hash of the page data
+    memhash: Hash,
+    /// The following could be in a separate structure
+    memory: Vec<u8>,
+}
+```
+
+The guarantee that runtime enforces:
+    1. The contract code is the only code that will modify the contents of `memory`
+    2. Total balances on all the pages is equal before and after exectuion of a call
+    3. Balances of each of the pages not owned by the contract must be equal to or greater after the call than before the call.
+
+## Entry Point
+Exectuion of the contract involves maping the contract's public key to an entry point which takes a pointer to the transaction, and an array of loaded pages.
+```
+// Find the method
+match (tx.contract, tx.method) {
+    // system interface
+    // everyone has the same reallocate
+    (_, 0) => system_0_realloc(&tx, &mut call_pages),
+    (_, 1) => system_1_assign(&tx, &mut call_pages),
+    // contract methods
+    (DEFAULT_CONTRACT, 128) => default_contract_128_move_funds(&tx, &mut call_pages),
+    (contract, method) => //... 
+```
+
+The first 127 methods are reserved for the system interface, which implements allocation and assignment of memory.  The rest, including the contract for moving funds are implemented by the contract itself.
+
+## System Interface
+```
+/// SYSTEM interface, same for very contract, methods 0 to 127
+/// method 0
+/// reallocate
+/// spend the funds from the call to the first recipient's
+pub fn system_0_realloc(call: &Call, pages: &mut Vec<Page>) {
+    if call.contract == DEFAULT_CONTRACT {
+        let size: u64 = deserialize(&call.userdata).unwrap();
+        pages[0].memory.resize(size as usize, 0u8);
+    }
+}
+/// method 1
+/// assign
+/// assign the page to a contract
+pub fn system_1_assign(call: &Call, pages: &mut Vec<Page>) {
+    let contract = deserialize(&call.userdata).unwrap();
+    if call.contract == DEFAULT_CONTRACT {
+        pages[0].contract = contract;
+        //zero out the memory in pages[0].memory
+        //Contracts need to own the state of that data otherwise a use could fabricate the state and
+        //manipulate the contract
+        pages[0].memory.clear();
+    }
+} 
+```
+The first method resizes the memory that is assosciated with the callers page.  The second system call assignes the page to the contract.  Both methods check if the current contract is 0, otherwise the method does nothing and the caller spent their fees.
+
+This ensures that when memory is assigned to the contract the initial state of all the bytes is 0, and the contract itself is the only thing that can modify that state.
+
+## Simplest contract
+```
+/// DEFAULT_CONTRACT interface
+/// All contracts start with 128
+/// method 128
+/// move_funds
+/// spend the funds from the call to the first recipient's
+pub fn default_contract_128_move_funds(call: &Call, pages: &mut Vec<Page>) {
+    let amount: u64 = deserialize(&call.userdata).unwrap();
+    if pages[0].balance >= amount  {
+        pages[0].balance -= amount;
+        pages[1].balance += amount;
+    }
+}
+``` 
+
+This simply moves the amount from page[0], which is the callers page, to page[1], which is the recipient's page.

+
+Two players want to play tic-tac-toe with each other on Solana.
+
+The tic-tac-toe program has already been provisioned on the network, and the
+program author has advertised the following information to potential gamers:
+* `tictactoe_publickey` - the program's public key
+* `tictactoe_gamestate_size` - the number of bytes needed to maintain the game state
+
+The game state is a well-documented data structure consisting of:
+- Player 1's public key
+- Player 2's public key
+- Game status. An 8-bit value where:
+  * 0 = game uninitialized
+  * 1 = Player 1's turn
+  * 2 = Player 2's turn
+  * 3 = Player 1 won
+  * 4 = Player 2 won
+- Current board configuration.  A 3x3 character array containing the values '\0', 'X' or 'O'
+
+### Game Setup
+
+1. Two players want to start a game.  Player 2 sends Player 1 their public key,
+`player2_publickey` off-chain (IM, email, etc)
+
+2. Player 1 creates a new keypair to represent the game state, `(gamestate_publickey,
+gamestate_privatekey)`.
+
+3. Player 1 issues an allocate_memory transaction, assigning that memory page to the
+tic-tac-toe program.  The `memory_fee` is used to *rent* the memory page for the
+duration of the game and is subtracted from current account balance of Player
+1:
+```
+allocate_memory(gamestate_publickey, tictactoe_publickey, tictactoe_gamestate_size, memory_fee)
+```
+
+
+4. Game state is then initialized by issuing a *new* call transaction to the
+tic-tac-toe program.  This transaction is signed by `gamestate_privatekey`, known only
+to Player 1.
+```
+call(tictactoe_publickey, gamestate_publickey, 'new', player1_publickey, player2_publickey)
+```
+
+5. Once the game is initialized, Player 1 shares `gamestate_publickey` with
+Player 2 off-chain (IM, email, etc)
+
+Note that it's likely each player prefer to generate a game-specific keypair
+rather than sharing their primary public key (`player1_publickey`,
+`player2_publickey`) with each other and the tic-tac-toe program.
+
+### Game Play
+
+Both players poll the network, via a **TBD off-chain RPC API**, to read the
+current game state from the `gamestate_publickey` memory page.
+
+When the *Game status* field indicates it's their turn, the player issues a
+*move* call transaction passing in the board position (1..9) that they want to
+mark as X or O:
+```
+call(tictactoe_publickey, gamestate_publickey, 'move', position)
+```
+The program will reject the transaction if it was not signed by the player whose
+turn it is.
+
+The outcome of the *move* call is also observed by polling the current game state via
+the **TBD off-chain RPC API**.
+
+### Game Cancellation
+
+At any time Player 1 may conclude the game by issuing:
+```
+call(tictactoe_publickey, gamestate_publickey, 'abort')
+```
+causing any remaining *rent* tokens assigned to the `gamestate_publickey` page
+to be transferred back to Player 1 by the tic-tac-toe program.  Lastly, the
+network recognizes the empty account and frees the `gamestate_publickey` memory
+page.

+## Branches and Tags
+
+### master branch
+All new development occurs on the `master` branch.
+
+Bug fixes that affect a `vX.Y` branch are first made on `master`.  This is to
+allow a fix some soak time on `master` before it is applied to one or more
+stabilization branches.
+
+Merging to `master` first also helps ensure that fixes applied to one release
+are present for future releases.  (Sometimes the joy of landing a critical
+release blocker in a branch causes you to forget to propagate back to
+`master`!)"
+
+Once the bug fix lands on `master` it is cherry-picked into the `vX.Y` branch
+and potentially the `vX.Y-1` branch.  The exception to this rule is when a bug
+fix for `vX.Y` doesn't apply to `master` or `vX.Y-1`.
+
+Immediately after a new stabilization branch is forged, the `Cargo.toml` minor
+version (*Y*) in the `master` branch is incremented by the release engineer.
+Incrementing the major version of the `master` branch is outside the scope of
+this document.
+
+### v*X.Y* stabilization branches
+These are stabilization branches for a given milestone.  They are created off
+the `master` branch as late as possible prior to the milestone release.
+
+### v*X.Y.Z* release tag
+The release tags are created as desired by the owner of the given stabilization
+branch, and cause that *X.Y.Z* release to be shipped to https://crates.io,
+https://snapcraft.io/, and elsewhere.
+
+Immediately after a new v*X.Y.Z* branch tag has been created, the `Cargo.toml`
+patch version number (*Z*) of the stabilization branch is incremented by the
+release engineer.
+
+## Channels
+Channels are used by end-users (humans and bots) to consume the branches
+described in the previous section, so they may automatically update to the most
+recent version matching their desired stability.
+
+There are three release channels that map to branches as follows:
+* edge - tracks the `master` branch, least stable.
+* beta - tracks the largest (and latest) `vX.Y` stabilization branch, more stable.
+* stable - tracks the second largest `vX.Y` stabilization branch, most stable.
