+
+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

-[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.solama.com/mainnet-beta.solana.com
-See the documentation at https://github.com/solana-labs/cluster-ops/
+### 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

+# Programming Model
+
+An _app_ interacts with a Solana cluster by sending it _transactions_ with one or more _instructions_. The Solana _runtime_ passes those instructions to user-contributed _programs_. An instruction might, for example, tell a program to transfer _lamports_ from one _account_ to another or create an interactive contract that governs how lamports are transfered. Instructions are executed sequentially and atomically. If any instruction is invalid, any changes made within the transaction are discarded.
+
+### Accounts and Signatures
+
+Each transaction explicitly lists all account public keys referenced by the transaction's instructions. A subset of those public keys are each accompanied by a transaction signature. Those signatures signal on-chain programs that the account holder has authorized the transaction. Typically, the program uses the authorization to permit debiting the account or modifying its data.
+
+The transaction also marks some accounts as _read-only accounts_. The runtime permits read-only accounts to be read concurrently. If a program attempts to modify a read-only account, the transaction is rejected by the runtime.
+
+### Recent Blockhash
+
+A Transaction includes a recent blockhash to prevent duplication and to give transactions lifetimes. Any transaction that is completely identical to a previous one is rejected, so adding a newer blockhash allows multiple transactions to repeat the exact same action. Transactions also have lifetimes that are defined by the blockhash, as any transaction whose blockhash is too old will be rejected.
+
+### Instructions
+
+Each instruction specifies a single program account \(which must be marked executable\), a subset of the transaction's accounts that should be passed to the program, and a data byte array instruction that is passed to the program. The program interprets the data array and operates on the accounts specified by the instructions. The program can return successfully, or with an error code. An error return causes the entire transaction to fail immediately.
+
+## Deploying Programs to a Cluster
+
+![SDK tools](../.gitbook/assets/sdk-tools.svg)
+
+As shown in the diagram above a client creates a program and compiles it to an ELF shared object containing BPF bytecode and sends it to the Solana cluster. The cluster stores the program locally and makes it available to clients via a _program ID_. The program ID is a _public key_ generated by the client and is used to reference the program in subsequent transactions.
+
+A program may be written in any programming language that can target the Berkley Packet Filter \(BPF\) safe execution environment. The Solana SDK offers the best support for C programs, which is compiled to BPF using the [LLVM compiler infrastructure](https://llvm.org).
+
+## Storing State between Transactions
+
+If the program needs to store state between transactions, it does so using _accounts_. Accounts are similar to files in operating systems such as Linux. Like a file, an account may hold arbitrary data and that data persists beyond the lifetime of a program. Also like a file, an account includes metadata that tells the runtime who is allowed to access the data and how. Unlike a file, the account includes metadata for the lifetime of the file. That lifetime is expressed in "tokens", which is a number of fractional native tokens, called _lamports_. Accounts are held in validator memory and pay "rent" to stay there. Each validator periodically scan all accounts and collects rent. Any account that drops to zero lamports is purged.
+
+If an account is marked "executable", it will only be used by a _loader_ to run programs. For example, a BPF-compiled program is marked executable and loaded by the BPF loader. No program is allowed to modify the contents of an executable account.
+
+An account also includes "owner" metadata. The owner is a program ID. The runtime grants the program write access to the account if its ID matches the owner. If an account is not owned by a program, the program is permitted to read its data and credit the account.
+
+In the same way that a Linux user uses a path to look up a file, a Solana client uses public keys to look up accounts. To create an account, the client generates a _keypair_ and registers its public key using the `CreateAccount` instruction. The account created by `CreateAccount` is called a _system account_ and is owned by a built-in program called the System program. The System program allows clients to transfer lamports and assign account ownership.
+
+The runtime only permits the owner to debit the account or modify its data. The program then defines additional rules for whether the client can modify accounts it owns. In the case of the System program, it allows users to transfer lamports by recognizing transaction signatures. If it sees the client signed the transaction using the keypair's _private key_, it knows the client authorized the token transfer.
+
+After the runtime executes each of the transaction's instructions, it uses the account metadata to verify that none of the access rules were violated. If a program violates an access rule, the runtime discards all account changes made by all instructions and marks the transaction as failed.
+
+## Smart Contracts
+
+Programs don't always require transaction signatures, as the System program does. Instead, the program may manage _smart contracts_. A smart contract is a set of constraints that once satisfied, signal to a program that a token transfer or account update is permitted. For example, one could use the Budget program to create a smart contract that authorizes a token transfer only after some date. Once evidence that the date has past, the contract progresses, and token transfer completes.

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 validator 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.

 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.

-# Ledger Replication Not Implemented
-
-Replication behavior yet to be implemented.
-
-## 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
-
-```text
-SubmitMiningProof {
-    slot: u64,
-    sha_state: Hash,
-    signature: Signature,
-};
-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.
 
-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:

-Fast, reliable synchronization is the biggest reason Solana is able to achieve such high throughput. Traditional blockchains synchronize on large chunks of transactions called blocks. By synchronizing on blocks, a transaction cannot be processed until a duration, called "block time", has passed. In Proof of Work consensus, these block times need to be very large \(~10 minutes\) to minimize the odds of multiple validators producing a new valid block at the same time. There's no such constraint in Proof of Stake consensus, but without reliable timestamps, a validator cannot determine the order of incoming blocks. The popular workaround is to tag each block with a [wallclock timestamp](https://en.bitcoin.it/wiki/Block_timestamp). Because of clock drift and variance in network latencies, the timestamp is only accurate within an hour or two. To workaround the workaround, these systems lengthen block times to provide reasonable certainty that the median timestamp on each block is always increasing.

 Solana takes a very different approach, which it calls _Proof of History_ or _PoH_. Leader nodes "timestamp" blocks with cryptographic proofs that some duration of time has passed since the last proof. All data hashed into the proof most certainly have occurred before the proof was generated. The node then shares the new block with validator nodes, which are able to verify those proofs. The blocks can arrive at validators in any order or even could be replayed years later. With such reliable synchronization guarantees, Solana is able to break blocks into smaller batches of transactions called _entries_. Entries are streamed to validators in realtime, before any notion of block consensus.

 A desirable property of a VDF is that verification time is very fast. Solana's approach to verifying its delay function is proportional to the time it took to create it. Split over a 4000 core GPU, it is sufficiently fast for Solana's needs, but if you asked the authors of the paper cited above, they might tell you \([and have](https://github.com/solana-labs/solana/issues/388)\) that Solana's approach is algorithmically slow and it shouldn't be called a VDF. We argue the term VDF should represent the category of verifiable delay functions and not just the subset with certain performance characteristics. Until that's resolved, Solana will likely continue using the term PoH for its application-specific VDF.
 
-Another difference between PoH and VDFs is that a VDF is used only for tracking duration. PoH's hash chain, on the other hand, includes hashes of any data the application observed. That data is a double-edged sword. On one side, the data "proves history" - that the data most certainly existed before hashes after it. On the other side, it means the application can manipulate the hash chain by changing _when_ the data is hashed. The PoH chain therefore does not serve as a good source of randomness whereas a VDF without that data could. Solana's [leader rotation algorithm](synchronization.md#leader-rotation), for example, is derived only from the VDF _height_ and not its hash at that height.

 A Solana cluster uses a multi-layer block propagation mechanism called _Turbine_ to broadcast transaction shreds to all nodes with minimal amount of duplicate messages. The cluster divides itself into small collections of nodes, called _neighborhoods_. Each node is responsible for sharing any data it receives with the other nodes in its neighborhood, as well as propagating the data on to a small set of nodes in other neighborhoods. This way each node only has to communicate with a small number of nodes.

 ## Neighborhood Assignment - Weighted Selection
 
-In order for data plane fanout to work, the entire cluster must agree on how the cluster is divided into neighborhoods. To achieve this, all the recognized validator nodes \(the TVU peers\) are sorted by stake and stored in a list. This list is then indexed in different ways to figure out neighborhood boundaries and retransmit peers. For example, the leader will simply select the first nodes to make up layer 0. These will automatically be the highest stake holders, allowing the heaviest votes to come back to the leader first. Layer 0 and lower-layer nodes use the same logic to find their neighbors and next layer peers.

-The current leader makes its initial broadcasts to at most `DATA_PLANE_FANOUT` nodes. If this layer 0 is smaller than the number of nodes in the cluster, then the data plane fanout mechanism adds layers below.

 ## Neighborhoods
 
 The following diagram shows how two neighborhoods in different layers interact. To cripple a neighborhood, enough nodes \(erasure codes +1\) from the neighborhood above need to fail. Since each neighborhood receives shreds from multiple nodes in a neighborhood in the upper layer, we'd need a big network failure in the upper layers to end up with incomplete data.
