+
+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.

+
+## 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

 ### 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
+     scripts/increment-cargo-version.sh patch
      ```
+1. Rebuild to get an updated version of `Cargo.lock`:
+    ```
+    cargo build
+    ```
 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
+    git co -b version_update
+    git ls-files -m | xargs git add
+    git commit -m 'Update Cargo.toml versions from X.Y.Z to X.Y.Z+1'
+    git push -u origin 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.
+1. 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.  This can take up to 90 minutes after creating the tag.
+1. The `solana-secondary` Buildkite pipeline handles creating the binary tarballs and updated crates.  Look for a job under the tag name of the release: https://buildkite.com/solana-labs/solana-secondary
+1. [Crates.io](https://crates.io/crates/solana) should have an updated Solana version.
 
-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
+### Update documentation
+TODO: Documentation update procedure is WIP as we move to gitbook
 
-[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
+Document the new recommended version by updating `book/src/running-archiver.md` and `book/src/validator-testnet.md` on the release (beta) branch to point at the `solana-install` for the upcoming release version.
 
-### Update software on devnet.solana.com/testnet.solana.com/mainnet-beta.solana.com
-See the documentation at https://github.com/solana-labs/cluster-ops/
+#### Publish updated Book
+We maintain three copies of the "book" as official documentation:
+
+1) "Book" is the documentation for the latest official release.  This should get manually updated whenever a new release is made.  It is published here:
+https://solana-labs.github.io/book/
+
+2) "Book-edge" tracks the tip of the master branch and updates automatically.
+https://solana-labs.github.io/book-edge/
+
+3) "Book-beta" tracks the tip of the beta branch and updates automatically.
+https://solana-labs.github.io/book-beta/
+
+To manually trigger an update of the "Book", create a new job of the manual-update-book pipeline.
+Set the tag of the latest release as the PUBLISH_BOOK_TAG environment variable.
+```bash
+PUBLISH_BOOK_TAG=v0.16.6
+```
+https://buildkite.com/solana-labs/manual-update-book
+
+### Update software on testnet.solana.com
+
+The testnet running on testnet.solana.com is set to use a fixed release tag
+which is set in the Buildkite testnet-management pipeline.
+This tag needs to be updated and the testnet restarted after a new release
+tag is created.
+
+#### Update testnet schedules
+
+Go to https://buildkite.com/solana-labs and click through: Pipelines ->
+testnet-management -> Pipeline Settings -> Schedules
+Or just click here:
+https://buildkite.com/solana-labs/testnet-management/settings/schedules
+
+There are two scheduled jobs for testnet: a daily restart and an hourly sanity-or-restart. \
+https://buildkite.com/solana-labs/testnet-management/settings/schedules/0efd7856-7143-4713-8817-47e6bdb05387
+https://buildkite.com/solana-labs/testnet-management/settings/schedules/2a926646-d972-42b5-aeb9-bb6759592a53
+
+On each schedule:
+1.  Set TESTNET_TAG environment variable to the desired release tag.
+    1. Example, TESTNET_TAG=v0.13.2
+1.  Set the Build Branch to the branch that TESTNET_TAG is from.
+    1. Example: v0.13
+
+#### Restart the testnet
+
+Trigger a TESTNET_OP=create-and-start to refresh the cluster with the new version
+
+1.  Go to https://buildkite.com/solana-labs/testnet-management
+2.  Click "New Build" and use the following settings, then click "Create Build"
+    1.  Commit: HEAD
+    1.  Branch: [channel branch as set in the schedules]
+    1.  Environment Variables:
+```
+TESTNET=testnet
+TESTNET_TAG=[same value as used in TESTNET_TAG in the schedules]
+TESTNET_OP=create-and-start
+```
+
+### Alert the community
+
+Notify Discord users on #validator-support that a new release for
+testnet.solana.com is available

+# Blockstreamer
+
+Solana supports a node type called an _blockstreamer_. This validator variation is intended for applications that need to observe the data plane without participating in transaction validation or ledger replication.
+
+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/validator-x.sh --no-signer --blockstream <SOCKET>
+```
+
+The stream will output a series of JSON objects:
+
+* An Entry event JSON object is sent when each ledger entry is processed, with the following fields:
+  * `dt`, the system datetime, as RFC3339-formatted string
+  * `t`, the event type, always "entry"
+  * `s`, the slot height, as unsigned 64-bit integer
+  * `h`, the tick height, as unsigned 64-bit integer
+  * `entry`, the entry, as JSON object
+* A Block event JSON object is sent when a block is complete, with the following fields:
+  * `dt`, the system datetime, as RFC3339-formatted string
+  * `t`, the event type, always "block"
+  * `s`, the slot height, as unsigned 64-bit integer
+  * `h`, the tick height, as unsigned 64-bit integer
+  * `l`, the slot leader id, as base-58 encoded string
+  * `hash`, the [blockhash](terminology.md#blockhash), as base-58 encoded string

+# Transaction
+
+## Components of a `Transaction`
+
+* **Transaction:**
+  * **message:** Defines the transaction
+    * **header:** Details the account types of and signatures required by
+
+      the transaction
+
+      * **num\_required\_signatures:** The total number of signatures
+
+        required to make the transaction valid.
+
+      * **num\_credit\_only\_signed\_accounts:** The last
+
+        `num_readonly_signed_accounts` signatures refer to signing
+
+        credit only accounts. Credit only accounts can be used concurrently
+
+        by multiple parallel transactions, but their balance may only be
+
+        increased, and their account data is read-only.
+
+      * **num\_credit\_only\_unsigned\_accounts:** The last
+
+        `num_readonly_unsigned_accounts` public keys in `account_keys` refer
+
+        to non-signing credit only accounts
+
+    * **account\_keys:** List of public keys used by the transaction, including
+
+      by the instructions and for signatures. The first
+
+      `num_required_signatures` public keys must sign the transaction.
+
+    * **recent\_blockhash:** The ID of a recent ledger entry. Validators will
+
+      reject transactions with a `recent_blockhash` that is too old.
+
+    * **instructions:** A list of [instructions](https://github.com/solana-labs/solana/tree/aacead62c0eb052068172eba6b53fc85874d6d54/book/src/instruction.md) that are
+
+      run sequentially and committed in one atomic transaction if all
+
+      succeed.
+  * **signatures:** A list of signatures applied to the transaction. The
+
+    list is always of length `num_required_signatures`, and the signature
+
+    at index `i` corresponds to the public key at index `i` in `account_keys`.
+
+    The list is initialized with empty signatures \(i.e. zeros\), and
+
+    populated as signatures are added.
+
+## Transaction Signing
+
+A `Transaction` is signed by using an ed25519 keypair to sign the serialization of the `message`. The resulting signature is placed at the index of `signatures` matching the index of the keypair's public key in `account_keys`.
+
+## Transaction Serialization
+
+`Transaction`s \(and their `message`s\) are serialized and deserialized using the [bincode](https://crates.io/crates/bincode) crate with a non-standard vector serialization that uses only one byte for the length if it can be encoded in 7 bits, 2 bytes if it fits in 14 bits, or 3 bytes if it requires 15 or 16 bits. The vector serialization is defined by Solana's [short-vec](https://github.com/solana-labs/solana/blob/master/sdk/src/short_vec.rs).

 A validator votes on a PoH hash for two purposes. First, the vote indicates it
 believes the ledger is valid up until that point in time. Second, since many
 valid forks may exist at a given height, the vote also indicates exclusive
 support for the fork. This document describes only the former. The latter is

-A Solana cluster is a set of validators 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 section, 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.

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 validators, one first needs to create a _genesis config_. The config references two public keys, a _mint_ and a _bootstrap validator_. The validator holding the bootstrap validator's private 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 config. The second validator then contacts the bootstrap validator to register as a _validator_. Additional validators then register with any registered member of the cluster.

That account will hold the number of native tokens defined by the genesis config. The second validator then contacts the bootstrap leader to register as a _validator_ or _archiver_. Additional validators 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 archiver 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
 
-Validators 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 validator'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, effectively appending them to the ledger.

 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.

 Note that only data from leader L3 will be accepted during leader slot L3. Data from L3 may include "catchup" ticks back to a slot other than L2 if L3 did not observe L2's data. L4 and L5's transmissions include the "ticks to prev" PoH entries.

+# Leader Rotation
 
 At any given moment, a cluster expects only one validator to produce ledger entries. By having only one leader at a time, all validators are able to replay identical copies of the ledger. The drawback of only one leader at a time, however, is that a malicious leader is capable of censoring votes and transactions. Since censoring cannot be distinguished from the network dropping packets, the cluster cannot simply elect a single node to hold the leader role indefinitely. Instead, the cluster minimizes the influence of a malicious leader by rotating which node takes the lead.
 
-Each validator selects the expected leader using the same algorithm, described below. When the validator receives a new signed ledger entry, it can be certain that an entry was produced by the expected leader. The order of slots which each leader is assigned a slot is called a _leader schedule_.

-## Storage epoch
-
-The storage epoch should be the number of slots which results in around 100GB-1TB of ledger to be generated for archivers to store. Archivers will start storing ledger when a given fork has a high probability of not being rolled back.
-
-## Validator behavior
-
-1. Every NUM_KEY_ROTATION_TICKS it also validates samples received from
-
-   archivers. It signs the PoH hash at that point and uses the following
-
-   algorithm with the signature as the input:
-
-   - The low 5 bits of the first byte of the signature creates an index into
-
-     another starting byte of the signature.
-
-   - The validator then looks at the set of storage proofs where the byte of
-
-     the proof's sha state vector starting from the low byte matches exactly
-
-     with the chosen byte\(s\) of the signature.
-
-   - If the set of proofs is larger than the validator can handle, then it
-
-     increases to matching 2 bytes in the signature.
-
-   - Validator continues to increase the number of matching bytes until a
-
-     workable set is found.
-
-   - It then creates a mask of valid proofs and fake proofs and sends it to
-
-     the leader. This is a storage proof confirmation transaction.
-
-2. After a lockout period of NUM_SECONDS_STORAGE_LOCKOUT seconds, the
-
-   validator then submits a storage proof claim transaction which then causes the
-
-   distribution of the storage reward if no challenges were seen for the proof to
-
-   the validators and archivers party to the proofs.
-
-## Archiver behavior
-
-1. The archiver then generates another set of offsets which it submits a fake
-
-   proof with an incorrect sha state. It can be proven to be fake by providing the
-
-   seed for the hash result.
-
-   - A fake proof should consist of an archiver hash of a signature of a PoH
-
-     value. That way when the archiver reveals the fake proof, it can be
-
-     verified on chain.
-
-2. The archiver monitors the ledger, if it sees a fake proof integrated, it
-
-   creates a challenge transaction and submits it to the current leader. The
-
-   transacation proves the validator incorrectly validated a fake storage proof.
-
-   The archiver is rewarded and the validator's staking balance is slashed or
-
-   frozen.
-
-## Storage proof contract logic
-
-Each archiver and validator will have their own storage account. The validator's account would be separate from their gossip id similiar to their vote account. These should be implemented as two programs one which handles the validator as the keysigner and one for the archiver. In that way when the programs reference other accounts, they can check the program id to ensure it is a validator or archiver account they are referencing.

-SubmitMiningProof {

-keys = [archiver_keypair]

-
-Archivers create these after mining their stored ledger data for a certain hash value. The slot is the end slot of the segment of ledger they are storing, the sha_state the result of the archiver using the hash function to sample their encrypted ledger segment. The signature is the signature that was created when they signed a PoH value for the current storage epoch. The list of proofs from the current storage epoch should be saved in the account state, and then transfered to a list of proofs for the previous epoch when the epoch passes. In a given storage epoch a given archiver should only submit proofs for one segment.
-
-The program should have a list of slots which are valid storage mining slots. This list should be maintained by keeping track of slots which are rooted slots in which a significant portion of the network has voted on with a high lockout value, maybe 32-votes old. Every SLOTS_PER_SEGMENT number of slots would be added to this set. The program should check that the slot is in this set. The set can be maintained by receiving a AdvertiseStorageRecentBlockHash and checking with its bank/Tower BFT state.
-
-The program should do a signature verify check on the signature, public key from the transaction submitter and the message of the previous storage epoch PoH value.
-
-### ProofValidation
-
-```text
-ProofValidation {
-   proof_mask: Vec<ProofStatus>,
-}
-keys = [validator_keypair, archiver_keypair(s) (unsigned)]
-```
-
-A validator will submit this transaction to indicate that a set of proofs for a given segment are valid/not-valid or skipped where the validator did not look at it. The keypairs for the archivers that it looked at should be referenced in the keys so the program logic can go to those accounts and see that the proofs are generated in the previous epoch. The sampling of the storage proofs should be verified ensuring that the correct proofs are skipped by the validator according to the logic outlined in the validator behavior of sampling.
-
-The included archiver keys will indicate the the storage samples which are being referenced; the length of the proof_mask should be verified against the set of storage proofs in the referenced archiver account\(s\), and should match with the number of proofs submitted in the previous storage epoch in the state of said archiver account.
-
-### ClaimStorageReward
-
-```text
-ClaimStorageReward {
-}
-keys = [validator_keypair or archiver_keypair, validator/archiver_keypairs (unsigned)]
-```
-
-Archivers and validators will use this transaction to get paid tokens from a program state where SubmitStorageProof, ProofValidation and ChallengeProofValidations are in a state where proofs have been submitted and validated and there are no ChallengeProofValidations referencing those proofs. For a validator, it should reference the archiver keypairs to which it has validated proofs in the relevant epoch. And for an archiver it should reference validator keypairs for which it has validated and wants to be rewarded.
-
-### ChallengeProofValidation
-
-```text
-ChallengeProofValidation {
-    proof_index: u64,
-    hash_seed_value: Vec<u8>,
-}
-keys = [archiver_keypair, validator_keypair]
-```
-
-This transaction is for catching lazy validators who are not doing the work to validate proofs. An archiver will submit this transaction when it sees a validator has approved a fake SubmitMiningProof transaction. Since the archiver is a light client not looking at the full chain, it will have to ask a validator or some set of validators for this information maybe via RPC call to obtain all ProofValidations for a certain segment in the previous storage epoch. The program will look in the validator account state see that a ProofValidation is submitted in the previous storage epoch and hash the hash_seed_value and see that the hash matches the SubmitMiningProof transaction and that the validator marked it as valid. If so, then it will save the challenge to the list of challenges that it has in its state.
-
-### AdvertiseStorageRecentBlockhash
-
-```text
-AdvertiseStorageRecentBlockhash {
-    hash: Hash,
-    slot: u64,
-}
-```
-
-Validators and archivers will submit this to indicate that a new storage epoch has passed and that the storage proofs which are current proofs should now be for the previous epoch. Other transactions should check to see that the epoch that they are referencing is accurate according to current chain state.

+# Managing Forks
 
-The ledger is permitted to fork at slot boundaries. The resulting data structure forms a tree called a _blockstore_. When the validator interprets the blockstore, it must maintain state for each fork in the chain. We call each instance an _active fork_. It is the responsibility of a validator to weigh those forks, such that it may eventually select a fork.
+The ledger is permitted to fork at slot boundaries. The resulting data structure forms a tree called a _blocktree_. When the validator interprets the blocktree, it must maintain state for each fork in the chain. We call each instance an _active fork_. It is the responsibility of a validator to weigh those forks, such that it may eventually select a fork.
 
-A validator selects a fork by submiting a vote to a slot leader on that fork. The vote commits the validator for a duration of time called a _lockout period_. The validator is not permitted to vote on a different fork until that lockout period expires. Each subsequent vote on the same fork doubles the length of the lockout period. After some cluster-configured number of votes \(currently 32\), the length of the lockout period reaches what's called _max lockout_. Until the max lockout is reached, the validator has the option to wait until the lockout period is over and then vote on another fork. When it votes on another fork, it performs an operation called _rollback_, whereby the state rolls back in time to a shared checkpoint and then jumps forward to the tip of the fork that it just voted on. The maximum distance that a fork may roll back is called the _rollback depth_. Rollback depth is the number of votes required to achieve max lockout. Whenever a validator votes, any checkpoints beyond the rollback depth become unreachable. That is, there is no scenario in which the validator will need to roll back beyond rollback depth. It therefore may safely _prune_ unreachable forks and _squash_ all checkpoints beyond rollback depth into the root checkpoint.

 ## Active Forks
 
 An active fork is as a sequence of checkpoints that has a length at least one longer than the rollback depth. The shortest fork will have a length exactly one longer than the rollback depth. For example:
 
-![Forks](/img/forks.svg)
+![Forks](../.gitbook/assets/forks.svg)
 
 The following sequences are _active forks_:
 
-- {4, 2, 1}
-- {5, 2, 1}
-- {6, 3, 1}
-- {7, 3, 1}
+* {4, 2, 1}
+* {5, 2, 1}
+* {6, 3, 1}
+* {7, 3, 1}
 
 ## Pruning and Squashing
 
 A validator may vote on any checkpoint in the tree. In the diagram above, that's every node except the leaves of the tree. After voting, the validator prunes nodes that fork from a distance farther than the rollback depth and then takes the opportunity to minimize its memory usage by squashing any nodes it can into the root.
 
-Starting from the example above, with a rollback depth of 2, consider a vote on 5 versus a vote on 6. First, a vote on 5:
+Starting from the example above, wth a rollback depth of 2, consider a vote on 5 versus a vote on 6. First, a vote on 5:
 
-![Forks after pruning](/img/forks-pruned.svg)
+![Forks after pruning](../.gitbook/assets/forks-pruned.svg)
 
 The new root is 2, and any active forks that are not descendants from 2 are pruned.
 
 Alternatively, a vote on 6:
 
-![Forks](/img/forks-pruned2.svg)
+![Forks](../.gitbook/assets/forks-pruned2.svg)
 
 The tree remains with a root of 1, since the active fork starting at 6 is only 2 checkpoints from the root.
