Remove lock files from programs/bpf/rust (#14150)

* adds the instance token to crds-labels for node-instance crds-values (#14037)

If a node "a" receives instance-info from node "b1" it will override any
instance-info associated with "b1" pubkey in its crds table. This makes
it less likely that when "b1" receives crds values from "a" (either
through pull or push), it sees other instances of itself (because node
"a" discarded them when it received "b1" instance info).

In order for the crds table to contain all instance-info associated with
the same pubkey at the same time, we need to add the instance tokens to
the keys in the crds table (i.e. the CrdsValueLabel).

(cherry picked from commit 409fe3bca1)

# Conflicts:
#	core/src/cluster_info.rs
#	core/src/crds_value.rs

* removes backport merge conflicts

-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

-    git commit -m 'Update Cargo.toml versions from X.Y.Z to X.Y.Z+1'
-    git push -u origin version_update
+    git co -b version_update origin/vX.Y
+    git add -u
+    git commit -m 'Bump version to X.Y.Z+1'
+    git push -u <user-remote> version_update
     ```
+1. Open a PR against origin/vX.Y and then merge the PR after passing CI.
+
+### Prepare for the next release
+1.  Go to [GitHub Releases](https://github.com/solana-labs/solana/releases) and create a new draft release for `X.Y.Z+1` with empty release nodes.  This allows people to incrementally add new release notes until it's time for the next 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
-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.
+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.
 
-### Update documentation
-TODO: Documentation update procedure is WIP as we move to gitbook
+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
 
-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.
+[Crates.io](https://crates.io/crates/solana) should have an updated Solana version.  This can take 2-3 hours, and sometimes fails in the `solana-secondary` job.
+If this happens and the error is non-fatal, click "Retry" on the "publish crate" job
 
-### Update software on testnet.solana.com
-
-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
+### Update software on devnet.solana.com/testnet.solama.com/mainnet-beta.solana.com
+See the documentation at https://github.com/solana-labs/cluster-ops/

-# 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.

-
-## Getting lamports to users
-
-You may have noticed you interacted with the Solana cluster without first needing to acquire lamports to pay transaction fees. Under the hood, the web app creates a new ephemeral identity and sends a request to an off-chain service for a signed transaction authorizing a user to start a new game. The service is called a _drone_. When the app sends the signed transaction to the Solana cluster, the drone's lamports are spent to pay the transaction fee and start the game. In a real world app, the drone might request the user watch an ad or pass a CAPTCHA before signing over its lamports.

-# Cluster Economics
-
-**Subject to change.**
-
-Solana’s crypto-economic system is designed to promote a healthy, long term self-sustaining economy with participant incentives aligned to the security and decentralization of the network. The main participants in this economy are validation-clients and replication-clients. Their contributions to the network, state validation and data storage respectively, and their requisite incentive mechanisms are discussed below.
-
-The main channels of participant remittances are referred to as protocol-based rewards and transaction fees. Protocol-based rewards are issuances from a global, protocol-defined, inflation rate. These rewards will constitute the total reward delivered to replication and validation clients, the remaining sourced from transaction fees. In the early days of the network, it is likely that protocol-based rewards, deployed based on predefined issuance schedule, will drive the majority of participant incentives to participate in the network.
-
-These protocol-based rewards, to be distributed to participating validation and replication clients, are to be a result of a global supply inflation rate, calculated per Solana epoch and distributed amongst the active validator set. As discussed further below, the per annum inflation rate is based on a pre-determined disinflationary schedule. This provides the network with monetary supply predictability which supports long term economic stability and security.
-
-Transaction fees are market-based participant-to-participant transfers, attached to network interactions as a necessary motivation and compensation for the inclusion and execution of a proposed transaction \(be it a state execution or proof-of-replication verification\). A mechanism for long-term economic stability and forking protection through partial burning of each transaction fee is also discussed below.
-
-A high-level schematic of Solana’s crypto-economic design is shown below in **Figure 1**. The specifics of validation-client economics are described in sections: [Validation-client Economics](ed_validation_client_economics/), [State-validation Protocol-based Rewards](ed_validation_client_economics/ed_vce_state_validation_protocol_based_rewards.md), [State-validation Transaction Fees](ed_validation_client_economics/ed_vce_state_validation_transaction_fees.md) and [Replication-validation Transaction Fees](ed_validation_client_economics/ed_vce_replication_validation_transaction_fees.md). Also, the chapter titled [Validation Stake Delegation](ed_validation_client_economics/ed_vce_validation_stake_delegation.md) closes with a discussion of validator delegation opportunties and marketplace. Additionally, in [Storage Rent Economics](ed_storage_rent_economics.md), we describe an implementation of storage rent to account for the externality costs of maintaining the active state of the ledger. The [Replication-client Economics](ed_replication_client_economics/) chapter will review the Solana network design for global ledger storage/redundancy and archiver-client economics \([Storage-replication rewards](ed_replication_client_economics/ed_rce_storage_replication_rewards.md)\) along with an archiver-to-validator delegation mechanism designed to aide participant on-boarding into the Solana economy discussed in [Replication-client Reward Auto-delegation](ed_replication_client_economics/ed_rce_replication_client_reward_auto_delegation.md). An outline of features for an MVP economic design is discussed in the [Economic Design MVP](ed_mvp.md) section. Finally, in chapter [Attack Vectors](ed_attack_vectors.md), various attack vectors will be described and potential vulnerabilities explored and parameterized.

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

-# Economic Sustainability
-
-**Subject to change.**
-
-Long term economic sustainability is one of the guiding principles of Solana’s economic design. While it is impossible to predict how decentralized economies will develop over time, especially economies with flexible decentralized governances, we can arrange economic components such that, under certain conditions, a sustainable economy may take shape in the long term. In the case of Solana’s network, these components take the form of token issuance \(via inflation\) and token burning’.
-
-The dominant remittances from the Solana mining pool are validator and archiver rewards. The disinflationary mechanism is a flat, protocol-specified and adjusted, % of each transaction fee.
-
-The Archiver rewards are to be delivered to archivers as a portion of the network inflation after successful PoRep validation. The per-PoRep reward amount is determined as a function of the total network storage redundancy at the time of the PoRep validation and the network goal redundancy. This function is likely to take the form of a discount from a base reward to be delivered when the network has achieved and maintained its goal redundancy. An example of such a reward function is shown in **Figure 3**
-
-**Figure 3**: Example PoRep reward design as a function of global network storage redundancy.
-
-In the example shown in Figure 1, multiple per PoRep base rewards are explored \(as a % of Tx Fee\) to be delivered when the global ledger replication redundancy meets 10X. When the global ledger replication redundancy is less than 10X, the base reward is discounted as a function of the square of the ratio of the actual ledger replication redundancy to the goal redundancy \(i.e. 10X\).

-The preceeding sections, outlined in the [Economic Design Overview](./), describe a long-term vision of a sustainable Solana economy. Of course, we don't expect the final implementation to perfectly match what has been described above. We intend to fully engage with network stakeholders throughout the implementation phases \(i.e. pre-testnet, testnet, mainnet\) to ensure the system supports, and is representative of, the various network participants' interests. The first step toward this goal, however, is outlining a some desired MVP economic features to be available for early pre-testnet and testnet participants. Below is a rough sketch outlining basic economic functionality from which a more complete and functional system can be developed.
-
-## MVP Economic Features
-
-* Faucet to deliver testnet SOLs to validators for staking and application development.
-* Mechanism by which validators are rewarded via network inflation.
-* Ability to delegate tokens to validator nodes
-* Validator set commission fees on interest from delegated tokens.
-* Archivers to receive fixed, arbitrary reward for submitting validated PoReps. Reward size mechanism \(i.e. PoRep reward as a function of total ledger redundancy\) to come later.
-* Pooling of archiver PoRep transaction fees and weighted distribution to validators based on PoRep verification \(see [Replication-validation Transaction Fees](ed_validation_client_economics/ed_vce_replication_validation_transaction_fees.md). It will be useful to test this protection against attacks on testnet.
-* Nice-to-have: auto-delegation of archiver rewards to validator.

-Replication-clients should be rewarded for providing the network with storage space. Incentivization of the set of archivers provides data security through redundancy of the historical ledger. Replication nodes are rewarded in proportion to the amount of ledger data storage provided, as proved by successfully submitting Proofs-of-Replication to the cluster.. These rewards are captured by generating and entering Proofs of Replication \(PoReps\) into the PoH stream which can be validated by Validation nodes as described above in the [Replication-validation Transaction Fees](../ed_validation_client_economics/ed_vce_replication_validation_transaction_fees.md) chapter.

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

-# Storage-replication Rewards

-
-Archiver-clients download, encrypt and submit PoReps for ledger block sections.3 PoReps submitted to the PoH stream, and subsequently validated, function as evidence that the submitting archiver client is indeed storing the assigned ledger block sections on local hard drive space as a service to the network. Therefore, archiver clients should earn protocol rewards proportional to the amount of storage, and the number of successfully validated PoReps, that they are verifiably providing to the network.
-
-Additionally, archiver clients have the opportunity to capture a portion of slashed bounties \[TBD\] of dishonest validator clients. This can be accomplished by an archiver client submitting a verifiably false PoRep for which a dishonest validator client receives and signs as a valid PoRep. This reward incentive is to prevent lazy validators and minimize validator-archiver collusion attacks, more on this below.

-## Storage Rent Economics
-
-Each transaction that is submitted to the Solana ledger imposes costs. Transaction fees paid by the submitter, and collected by a validator, in theory, account for the acute, transacitonal, costs of validating and adding that data to the ledger. At the same time, our compensation design for archivers (see [Replication-client Economics](ed_replication_client_economics.md)), in theory, accounts for the long term storage of the historical ledger. Unaccounted in this process is the mid-term storage of active ledger state, necessarily maintined by the rotating validator set. This type of storage imposes costs not only to validators but also to the broader network as active state grows so does data transmission and validation overhead. To account for these costs, we describe here our preliminary design and implementation of storage rent. 
-
-Storage rent can be paid via one of two methods:
-
-Method 1: Set it and forget it
-
-With this approach, accounts with two-years worth of rent deposits secured are exempt from network rent charges. By maintaining this minimum-balance, the broader network benefits from reduced liquitity and the account holder can trust that their `Account::data` will be retained for continual access/usage. 
-
-Method 2: Pay per byte
-
-If an account has less than two-years worth of deposited rent the network charges rent on a per-epoch basis, in credit for the next epoch (but in arrears when necessary). This rent is deducted at a rate specified in genesis, in lamports per kilobyte-year.
-
-For information on the technical implementation details of this design, see the [Rent](rent.md) section.

-
-Validator-clients are eligible to receive protocol-based \(i.e. inflation-based\) rewards issued via stake-based annual interest rates \(calculated per epoch\) by providing compute \(CPU+GPU\) resources to validate and vote on a given PoH state. These protocol-based rewards are determined through an algorithmic disinflationary schedule as a function of total amount of circulating tokens. The network is expected to launch with an annual inflation rate around 15%, set to decrease by 15% per year until a long-term stable rate of 1-2% is reached. These issuances are to be split and distributed to participating validators and archivers, with around 90% of the issued tokens allocated for validator rewards. Because the network will be distributing a fixed amount of inflation rewards across the stake-weighted valdiator set, any individual validator's interest rate will be a function of the amount of staked SOL in relation to the circulating SOL.
-
-Additionally, validator clients may earn revenue through fees via state-validation transactions and Proof-of-Replication \(PoRep\) transactions. For clarity, we separately describe the design and motivation of these revenue distriubutions for validation-clients below: state-validation protocol-based rewards, state-validation transaction fees and rent, and PoRep-validation transaction fees.

-As previously mentioned, validator-clients will also be responsible for validating PoReps submitted into the PoH stream by archiver-clients. In this case, validators are providing compute \(CPU/GPU\) and light storage resources to confirm that these replication proofs could only be generated by a client that is storing the referenced PoH leger block.
-
-While replication-clients are incentivized and rewarded through protocol-based rewards schedule \(see [Replication-client Economics](../ed_replication_client_economics/)\), validator-clients will be incentivized to include and validate PoReps in PoH through collection of transaction fees associated with the submitted PoReps and distribution of protocol rewards proportional to the validated PoReps. As will be described in detail in the Section 3.1, replication-client rewards are protocol-based and designed to reward based on a global data redundancy factor. I.e. the protocol will incentivize replication-client participation through rewards based on a target ledger redundancy \(e.g. 10x data redundancy\).
-
-The validation of PoReps by validation-clients is computationally more expensive than state-validation \(detail in the [Economic Sustainability](../ed_economic_sustainability.md) chapter\), thus the transaction fees are expected to be proportionally higher.
-
-There are various attack vectors available for colluding validation and replication clients, also described in detail below in [Economic Sustainability](../ed_economic_sustainability/README.md). To protect against various collusion attack vectors, for a given epoch, validator rewards are distributed across participating validation-clients in proportion to the number of validated PoReps in the epoch less the number of PoReps that mismatch the archivers challenge. The PoRep challenge game is described in [Ledger Replication](https://github.com/solana-labs/solana/blob/master/book/src/ledger-replication.md#the-porep-game). This design rewards validators proportional to the number of PoReps they process and validate, while providing negative pressure for validation-clients to submit lazy or malicious invalid votes on submitted PoReps \(note that it is computationally prohibitive to determine whether a validator-client has marked a valid PoRep as invalid\).

-# State-validation Protocol-based Rewards
-
-**Subject to change.**
-
-Validator-clients have two functional roles in the Solana network:
-
-* Validate \(vote\) the current global state of that PoH along with any Proofs-of-Replication \(see [Replication Client Economics](../ed_replication_client_economics/)\) that they are eligible to validate.
-* Be elected as ‘leader’ on a stake-weighted round-robin schedule during which time they are responsible for collecting outstanding transactions and Proofs-of-Replication and incorporating them into the PoH, thus updating the global state of the network and providing chain continuity.
-
-Validator-client rewards for these services are to be distributed at the end of each Solana epoch. As previously discussed, compensation for validator-clients is provided via a protocol-based annual inflation rate dispersed in proportion to the stake-weight of each validator \(see below\) along with leader-claimed transaction fees available during each leader rotation. I.e. during the time a given validator-client is elected as leader, it has the opportunity to keep a portion of each transaction fee, less a protocol-specified amount that is destroyed \(see [Validation-client State Transaction Fees](ed_vce_state_validation_transaction_fees.md)\). PoRep transaction fees are also collected by the leader client and validator PoRep rewards are distributed in proportion to the number of validated PoReps less the number of PoReps that mismatch an archiver's challenge. \(see [Replication-client Transaction Fees](ed_vce_replication_validation_transaction_fees.md)\)
-
-The effective protocol-based annual interest rate \(%\) per epoch received by validation-clients is to be a function of:
-
-* the current global inflation rate, derived from the pre-determined dis-inflationary issuance schedule \(see [Validation-client Economics](.)\)
-* the fraction of staked SOLs out of the current total circulating supply,
-* the up-time/participation \[% of available slots that validator had opportunity to vote on\] of a given validator over the previous epoch.
-
-The first factor is a function of protocol parameters only \(i.e. independent of validator behavior in a given epoch\) and results in a global validation reward schedule designed to incentivize early participation, provide clear montetary stability and provide optimal security in the network.
-
-At any given point in time, a specific validator's interest rate can be determined based on the porportion of circulating supply that is staked by the network and the validator's uptime/activity in the previous epoch. For example, consider a hypothetical instance of the network with an initial circulating token supply of 250MM tokens with an additional 250MM vesting over 3 years. Additionally an inflation rate is specified at network launch of 7.5%, and a disinflationary schedule of 20% decrease in inflation rate per year \(the actual rates to be implemented are to be worked out during the testnet experimentation phase of mainnet launch\). With these broad assumptions, the 10-year inflation rate \(adjusted daily for this example\) is shown in **Figure 2**, while the total circulating token supply is illustrated in **Figure 3**. Neglected in this toy-model is the inflation supression due to the portion of each transaction fee that is to be destroyed.
-
-![drawing](../../../.gitbook/assets/p_ex_schedule.png) \*\*Figure 2:\*\* In this example schedule, the annual inflation rate \[%\] reduces at around 20% per year, until it reaches the long-term, fixed, 1.5% rate.
-
-![drawing](../../../.gitbook/assets/p_ex_supply.png) \*\*Figure 3:\*\* The total token supply over a 10-year period, based on an initial 250MM tokens with the disinflationary inflation schedule as shown in \*\*Figure 2\*\* Over time, the interest rate, at a fixed network staked percentage, will reduce concordant with network inflation. Validation-client interest rates are designed to be higher in the early days of the network to incentivize participation and jumpstart the network economy. As previously mentioned, the inflation rate is expected to stabalize near 1-2% which also results in a fixed, long-term, interest rate to be provided to validator-clients. This value does not represent the total interest available to validator-clients as transaction fees for state-validation and ledger storage replication \(PoReps\) are not accounted for here. Given these example parameters, annualized validator-specific interest rates can be determined based on the global fraction of tokens bonded as stake, as well as their uptime/activity in the previous epoch. For the purpose of this example, we assume 100% uptime for all validators and a split in interest-based rewards between validators and archiver nodes of 80%/20%. Additionally, the fraction of staked circulating supply is assummed to be constant. Based on these assumptions, an annualized validation-client interest rate schedule as a function of % circulating token supply that is staked is shown in\*\* Figure 4\*\*.
-
-![drawing](../../../.gitbook/assets/p_ex_interest.png)
-
-**Figure 4:** Shown here are example validator interest rates over time, neglecting transaction fees, segmented by fraction of total circulating supply bonded as stake.
-
-This epoch-specific protocol-defined interest rate sets an upper limit of _protocol-generated_ annual interest rate \(not absolute total interest rate\) possible to be delivered to any validator-client per epoch. The distributed interest rate per epoch is then discounted from this value based on the participation of the validator-client during the previous epoch.

-Despite the low-barrier to entry as a validation-client, from a capital investment perspective, as in any developing economy, there will be much opportunity and need for trusted validation services as evidenced by node reliability, UX/UI, APIs and other software accessibility tools. Additionally, although Solana’s validator node startup costs are nominal when compared to similar networks, they may still be somewhat restrictive for some potential participants. In the spirit of developing a true decentralized, permissionless network, these interested parties still have two options to become involved in the Solana network/economy:
-
-1. Delegation of previously acquired tokens with a reliable validation node to earn a portion of interest generated
-2. Provide local storage space as a replication-client and receive rewards by submitting Proof-of-Replication \(see [Replication-client Economics](../ed_replication_client_economics/)\).
-
-   a. This participant has the additional option to directly delegate their earned storage rewards \([Replication-client Reward Auto-delegation](../ed_replication_client_economics/ed_rce_replication_client_reward_auto_delegation.md)\)
-
-Delegation of tokens to validation-clients, via option 1, provides a way for passive Solana token holders to become part of the active Solana economy and earn interest rates proportional to the interest rate generated by the delegated validation-client. Additionally, this feature intends to create a healthy validation-client market, with potential validation-client nodes competing to build reliable, transparent and profitable delegation services.

-# Rent
-
-Accounts on Solana may have owner-controlled state \(`Account::data`\) that's separate from the account's balance \(`Account::lamports`\). Since validators on the network need to maintain a working copy of this state in memory, the network charges a time-and-space based fee for this resource consumption, also known as Rent.
-
-## Two-tiered rent regime
-
-Accounts which maintain a minimum balance equivalent to 2 years of rent payments are exempt. Accounts whose balance falls below this threshold are charged rent at a rate specified in genesis, in lamports per kilobyte-year. The network charges rent on a per-epoch basis, in credit for the next epoch \(but in arrears when necessary\), and `Account::rent_epoch` keeps track of the next time rent should be collected from the account.
-
-## Collecting rent
-
-Rent is due at account creation time for one epoch's worth of time, and the new account has `Account::rent_epoch` of `current_epoch + 1`. After that, the bank deducts rent from accounts during normal transaction processing as part of the load phase.
-
-If the account is in the exempt regime, `Account::rent_epoch` is simply pushed to `current_epoch + 1`.
-
-If the account is non-exempt, the difference between the next epoch and `Account::rent_epoch` is used to calculate the amount of rent owed by this account \(via `Rent::due()`\). Any fractional lamports of the calculation are truncated. Rent due is deducted from `Account::lamports` and `Account::rent_epoch` is updated to the next epoch. If the amount of rent due is less than one lamport, no changes are made to the account.
-
-Accounts whose balance is insufficient to satisfy the rent that would be due simply fail to load.
-
-A percentage of the rent collected is destroyed. The rest is distributed to validator accounts by stake weight, a la transaction fees, at the end of every slot.
-
-## Read-only accounts
-
-Read-only accounts are not being charged rent in current implementation.
-
-## Design considerations, others considered
-
-Under this design, it is possible to have accounts that linger, never get touched, and never have to pay rent. `Noop` instructions that name these accounts can be used to "garbage collect", but it'd also be possible for accounts that never get touched to migrate out of a validator's working set, thereby reducing memory consumption and obviating the need to charge rent.
-
-### Ad-hoc collection
-
-Collecting rent on an as-needed basis \(i.e. whenever accounts were loaded/accessed\) was considered. The issues with such an approach are:
-
-* accounts loaded as "credit only" for a transaction could very reasonably be expected to have rent due,
-
-  but would not be writable during any such transaction
-
-* a mechanism to "beat the bushes" \(i.e. go find accounts that need to pay rent\) is desirable,
-
-  lest accounts that are loaded infrequently get a free ride
-
-### System instruction for collecting rent
-
-Collecting rent via a system instruction was considered, as it would naturally have distributed rent to active and stake-weighted nodes and could have been done incrementally. However:
-
-* it would have adversely affected network throughput
-* it would require special-casing by the runtime, as accounts with non-SystemProgram owners may be debited by this instruction
-* someone would have to issue the transactions
-
-### Account scans on every epoch
-
-Scanning the entire Bank for accounts that owe rent at the beginning of each epoch was considered. This would have been an expensive operation, and would require that the entire current state of the network be present on every validator at the beginning of each epoch.

-## Repair Service
-
-The RepairService is in charge of retrieving missing shreds that failed to be delivered by primary communication protocols like Avalanche. It is in charge of managing the protocols described below in the `Repair Protocols` section below.
-
-## Challenges:
-
-1\) Validators can fail to receive particular shreds due to network failures
-
-2\) Consider a scenario where blockstore contains the set of slots {1, 3, 5}. Then Blockstore receives shreds for some slot 7, where for each of the shreds b, b.parent == 6, so then the parent-child relation 6 -> 7 is stored in blockstore. However, there is no way to chain these slots to any of the existing banks in Blockstore, and thus the `Shred Repair` protocol will not repair these slots. If these slots happen to be part of the main chain, this will halt replay progress on this node.
-
-3\) Validators that find themselves behind the cluster by an entire epoch struggle/fail to catch up because they do not have a leader schedule for future epochs. If nodes were to blindly accept repair shreds in these future epochs, this exposes nodes to spam.
-
-## Repair Protocols
-
-The repair protocol makes best attempts to progress the forking structure of Blockstore.
-
-The different protocol strategies to address the above challenges:
-
-1. Shred Repair \(Addresses Challenge \#1\): This is the most basic repair protocol, with the purpose of detecting and filling "holes" in the ledger. Blockstore tracks the latest root slot. RepairService will then periodically iterate every fork in blockstore starting from the root slot, sending repair requests to validators for any missing shreds. It will send at most some `N` repair reqeusts per iteration.
-
-   Note: Validators will only accept shreds within the current verifiable epoch \(epoch the validator has a leader schedule for\).
-
-2. Preemptive Slot Repair \(Addresses Challenge \#2\): The goal of this protocol is to discover the chaining relationship of "orphan" slots that do not currently chain to any known fork.
-   * Blockstore will track the set of "orphan" slots in a separate column family.
-   * RepairService will periodically make `RequestOrphan` requests for each of the orphans in blockstore.
-
-     `RequestOrphan(orphan)` request - `orphan` is the orphan slot that the requestor wants to know the parents of `RequestOrphan(orphan)` response - The highest shreds for each of the first `N` parents of the requested `orphan`
-
-     On receiving the responses `p`, where `p` is some shred in a parent slot, validators will:
-
-     * Insert an empty `SlotMeta` in blockstore for `p.slot` if it doesn't already exist.
-     * If `p.slot` does exist, update the parent of `p` based on `parents`
-
-     Note: that once these empty slots are added to blockstore, the `Shred Repair` protocol should attempt to fill those slots.
-
-     Note: Validators will only accept responses containing shreds within the current verifiable epoch \(epoch the validator has a leader schedule for\).
-3. Repairmen \(Addresses Challenge \#3\): This part of the repair protocol is the primary mechanism by which new nodes joining the cluster catch up after loading a snapshot. This protocol works in a "forward" fashion, so validators can verify every shred that they receive against a known leader schedule.
-
-   Each validator advertises in gossip:
-
-   * Current root
-   * The set of all completed slots in the confirmed epochs \(an epoch that was calculated based on a bank <= current root\) past the current root
-
-     Observers of this gossip message with higher epochs \(repairmen\) send shreds to catch the lagging node up with the rest of the cluster. The repairmen are responsible for sending the slots within the epochs that are confrimed by the advertised `root` in gossip. The repairmen divide the responsibility of sending each of the missing slots in these epochs based on a random seed \(simple shred.index iteration by N, seeded with the repairman's node\_pubkey\). Ideally, each repairman in an N node cluster \(N nodes whose epochs are higher than that of the repairee\) sends 1/N of the missing shreds. Both data and coding shreds for missing slots are sent. Repairmen do not send shreds again to the same validator until they see the message in gossip updated, at which point they perform another iteration of this protocol.
-
-     Gossip messages are updated every time a validator receives a complete slot within the epoch. Completed slots are detected by blockstore and sent over a channel to RepairService. It is important to note that we know that by the time a slot X is complete, the epoch schedule must exist for the epoch that contains slot X because WindowService will reject shreds for unconfirmed epochs. When a newly completed slot is detected, we also update the current root if it has changed since the last update. The root is made available to RepairService through Blockstore, which holds the latest root.

-## What is Solana?
-
-Solana is an open source project implementing a new, high-performance, permissionless blockchain. Solana is also the name of a company headquartered in San Francisco that maintains the open source project.
-
-## About this Book
-
-This book describes the Solana open source project, a blockchain built from the ground up for scale. The book covers why Solana is useful, how to use it, how it works, and why it will continue to work long after the company Solana closes its doors. The goal of the Solana architecture is to demonstrate there exists a set of software algorithms that when used in combination to implement a blockchain, removes software as a performance bottleneck, allowing transaction throughput to scale proportionally with network bandwidth. The architecture goes on to satisfy all three desirable properties of a proper blockchain: it is scalable, secure and decentralized.
-
-The architecture describes a theoretical upper bound of 710 thousand transactions per second \(tps\) on a standard gigabit network and 28.4 million tps on 40 gigabit. Furthermore, the architecture supports safe, concurrent execution of programs authored in general purpose programming languages such as C or Rust.
-
-## Disclaimer

-All claims, content, designs, algorithms, estimates, roadmaps, specifications, and performance measurements described in this project are done with the author's best effort. It is up to the reader to check and validate their accuracy and truthfulness. Furthermore, nothing in this project constitutes a solicitation for investment.
-
-## History of the Solana Codebase
-
-In November of 2017, Anatoly Yakovenko published a whitepaper describing Proof of History, a technique for keeping time between computers that do not trust one another. From Anatoly's previous experience designing distributed systems at Qualcomm, Mesosphere and Dropbox, he knew that a reliable clock makes network synchronization very simple. When synchronization is simple the resulting network can be blazing fast, bound only by network bandwidth.
-
-Anatoly watched as blockchain systems without clocks, such as Bitcoin and Ethereum, struggled to scale beyond 15 transactions per second worldwide when centralized payment systems such as Visa required peaks of 65,000 tps. Without a clock, it was clear they'd never graduate to being the global payment system or global supercomputer most had dreamed them to be. When Anatoly solved the problem of getting computers that don’t trust each other to agree on time, he knew he had the key to bring 40 years of distributed systems research to the world of blockchain. The resulting cluster wouldn't be just 10 times faster, or a 100 times, or a 1,000 times, but 10,000 times faster, right out of the gate!
-
-Anatoly's implementation began in a private codebase and was implemented in the C programming language. Greg Fitzgerald, who had previously worked with Anatoly at semiconductor giant Qualcomm Incorporated, encouraged him to reimplement the project in the Rust programming language. Greg had worked on the LLVM compiler infrastructure, which underlies both the Clang C/C++ compiler as well as the Rust compiler. Greg claimed that the language's safety guarantees would improve software productivity and that its lack of a garbage collector would allow programs to perform as well as those written in C. Anatoly gave it a shot and just two weeks later, had migrated his entire codebase to Rust. Sold. With plans to weave all the world's transactions together on a single, scalable blockchain, Anatoly called the project Loom.
-
-On February 13th of 2018, Greg began prototyping the first open source implementation of Anatoly's whitepaper. The project was published to GitHub under the name Silk in the loomprotocol organization. On February 28th, Greg made his first release, demonstrating 10 thousand signed transactions could be verified and processed in just over half a second. Shortly after, another former Qualcomm cohort, Stephen Akridge, demonstrated throughput could be massively improved by offloading signature verification to graphics processors. Anatoly recruited Greg, Stephen and three others to co-found a company, then called Loom.
-
-Around the same time, Ethereum-based project Loom Network sprung up and many people were confused about whether they were the same project. The Loom team decided it would rebrand. They chose the name Solana, a nod to a small beach town North of San Diego called Solana Beach, where Anatoly, Greg and Stephen lived and surfed for three years when they worked for Qualcomm. On March 28th, the team created the Solana Labs GitHub organization and renamed Greg's prototype Silk to Solana.
-
-In June of 2018, the team scaled up the technology to run on cloud-based networks and on July 19th, published a 50-node, permissioned, public testnet consistently supporting bursts of 250,000 transactions per second. In a later release in December, called v0.10 Pillbox, the team published a permissioned testnet running 150 nodes on a gigabit network and demonstrated soak tests processing an _average_ of 200 thousand transactions per second with bursts over 500 thousand. The project was also extended to support on-chain programs written in the C programming language and run concurrently in a safe execution environment called BPF.

-## What is a Solana Cluster?
-
-A cluster is a set of computers that work together and can be viewed from the outside as a single system. A Solana cluster is a set of independently owned computers working together \(and sometimes against each other\) to verify the output of untrusted, user-submitted programs. A Solana cluster can be utilized any time a user wants to preserve an immutable record of events in time or programmatic interpretations of those events. One use is to track which of the computers did meaningful work to keep the cluster running. Another use might be to track the possession of real-world assets. In each case, the cluster produces a record of events called the ledger. It will be preserved for the lifetime of the cluster. As long as someone somewhere in the world maintains a copy of the ledger, the output of its programs \(which may contain a record of who possesses what\) will forever be reproducible, independent of the organization that launched it.
-
-## What are SOLs?
-
-A SOL is the name of Solana's native token, which can be passed to nodes in a Solana cluster in exchange for running an on-chain program or validating its output. The system may perform micropayments of fractional SOLs, which are called _lamports_. They are named in honor of Solana's biggest technical influence, [Leslie Lamport](https://en.wikipedia.org/wiki/Leslie_Lamport). A lamport has a value of 0.000000001 SOL.

-# Offline Transaction Signing
-
-Some security models require keeping signing keys, and thus the signing
-process, separated from transaction creation and network broadcast. Examples
-include:
-  * Collecting signatures from geographically disparate signers in a
-[multi-signature scheme](../api-reference/cli.md#multiple-witnesses)
-  * Signing transactions using an [airgapped](https://en.wikipedia.org/wiki/Air_gap_(networking))
-signing device
-
-This document describes using Solana's CLI to separately sign and submit a
-transaction.
-
-## Commands Supporting Offline Signing
-
-At present, the following commands support offline signing:
-  * [`delegate-stake`](../api-reference/cli.md#solana-delegate-stake)
-  * [`deactivate-stake`](../api-reference/cli.md#solana-deactivate-stake)
-  * [`pay`](../api-reference/cli.md#solana-pay)
-
-## Signing Transactions Offline
-
-To sign a transaction offline, pass the following arguments on the command line
-1) `--sign-only`, prevents the client from submitting the signed transaction
-to the network. Instead, the pubkey/signature pairs are printed to stdout. 
-2) `--blockhash BASE58_HASH`, allows the caller to specify the value used to
-fill the transaction's `recent_blockhash` field. This serves a number of
-purposes, namely:
-    * Eliminates the need to connect to the network and query a recent blockhash
-via RPC
-    * Enables the signers to coordinate the blockhash in a multiple-signature
-scheme
-
-### Example: Offline Signing a Payment
-
-Command
-
-```bash
-solana@offline$ solana pay --sign-only --blockhash 5Tx8F3jgSHx21CbtjwmdaKPLM5tWmreWAnPrbqHomSJF \
-    recipient-keypair.json 1 SOL

-```
-
-## Submitting Offline Signed Transactions to the Network
-
-To submit a transaction that has been signed offline to the network, pass the
-following arguments on the command line
-1) `--blockhash BASE58_HASH`, must be the same blockhash as was used to sign
-2) `--signer BASE58_PUBKEY=BASE58_SIGNATURE`, one for each offline signer. This
-includes the pubkey/signature pairs directly in the transaction rather than
-signing it with any local keypair(s)
-
-### Example: Submitting an Offline Signed Payment
-
-Command
-

-
-## Buying More Time to Sign
-
-Typically a Solana transaction must be signed and accepted by the network within
-a number of slots from the blockhash in its `recent_blockhash` field (~2min at
-the time of this writing). If your signing procedure takes longer than this, a
-[Durable Transaction Nonce](durable-nonce.md) can give you the extra time you

-# Paper Wallet Usage
-
-Solana commands can be run without ever saving a keypair to disk on a machine.
-If avoiding writing a private key to disk is a security concern of yours, you've
-come to the right place.
-
-{% hint style="warning" %}
-Even using this secure input method, it's still possible that a private key gets
-written to disk by unencrypted memory swaps. It is the user's responsibility to
-protect against this scenario.
-{% endhint %}
-
-## Creating a Paper Wallet
-
-Using the `solana-keygen` tool, it is possible to generate new seed phrases as
-well as derive a keypair from an existing seed phrase and (optional) passphrase.
-The seed phrase and passphrase can be used together as a paper wallet. As long
-as you keep your seed phrase and passphrase stored safely, you can use them to
-access your account.
-
-{% hint style="info" %}
-For more information about how seed phrases work, review this
-[Bitcoin Wiki page](https://en.bitcoin.it/wiki/Seed_phrase).
-{% endhint %}
-
-### Seed Phrase Generation
-
-Generating a new keypair can be done using the `solana-keygen new` command. The
-command will generate a random seed phrase, ask you to enter an optional
-passphrase, and then will display the derived public key and the generated seed
-phrase for your paper wallet.
-
-```bash
-solana-keygen new --no-outfile
-```
-
-{% hint style="warning" %}
-If the `--no-outfile` flag is **omitted**, the default behavior is to write the
-keypair to `~/.config/solana/id.json`
-{% endhint %}
-
-{% hint style="info" %}
-For added security, increase the seed phrase word count using the `--word-count`
-argument
-{% endhint %}
-
-For full usage details run:
-
-```bash
-solana-keygen new --help
-```
-
-### Public Key Derivation
-
-Public keys can be derived from a seed phrase and a passphrase if you choose to
-use one. This is useful for using an offline-generated seed phrase to
-derive a valid public key. The `solana-keygen pubkey` command will walk you
-through entering your seed phrase and a passphrase if you chose to use one.
-
-```bash
-solana-keygen pubkey ASK
-```
-
-{% hint style="info" %}
-Note that you could potentially use different passphrases for the same seed
-phrase. Each unique passphrase will yield a different keypair.
-{% endhint %}
-
-The `solana-keygen` tool uses the same BIP39 standard English word list as it
-does to generate seed phrases. If your seed phrase was generated with another
-tool that uses a different word list, you can still use `solana-keygen`, but
-will need to pass the `--skip-seed-phrase-validation` argument and forego this
-validation.
-
-```bash
-solana-keygen pubkey ASK --skip-seed-phrase-validation
-```
-
-{% hint style="info" %}
-Copy the derived public key to a USB stick for easy usage on networked computers
-{% endhint %}
-
-{% hint style="info" %}
-A common next step is to [check the balance](#checking-account-balance) of the
-account associated with a public key
-{% endhint %}
-
-For full usage details run:
-
-```bash
-solana-keygen pubkey --help
-```
-## Checking Account Balance
-
-All that is needed to check an account balance is the public key of an account.
-To retrieve public keys securely from a paper wallet, follow the
-[Public Key Derivation](#public-key-derivation) instructions on an
-[air gapped computer](https://en.wikipedia.org/wiki/Air_gap_\(networking\)).
-Public keys can then be typed manually or transferred via a USB stick to a
-networked machine.
-
-Next, configure the `solana` CLI tool to connect to a particular cluster:
-
-```bash
-solana config set --url <CLUSTER URL> # (i.e. http://testnet.solana.com:8899)
-```
-
-Finally, to check the balance, run the following command:
-
-```bash
-solana balance <PUBKEY>
-```
-
-In order to check a list of public keys quickly, append public keys to a file,
-one per line, like so:
-
-`public_keys.txt`
-```bash
-7hTw3XhprjT2DkVxVixtig9eZwHTZ2rksTSYN7Jh5niZ
-9ufAiSyboCZmmEsoStgLYQfnx9KfqP1ZtDK8Wr1j8SJV
-# ...
-```
-
-And run the following command:
-```bash
-while read PUBLIC_KEY;
-do echo "$PUBLIC_KEY: $(solana balance "$PUBLIC_KEY" | tail -n1)";
-done < public_keys.txt
-```
-
-## Running a Validator
-
-In order to run a validator, you will need to specify an "identity keypair"
-which will be used to fund all of the vote transactions signed by your validator.
-Rather than specifying a path with `--identity-keypair <PATH>` you can use the
-`--ask-seed-phrase` option.
-
-```bash
-solana-validator --ask-seed-phrase identity-keypair --ledger ...
-
-[identity-keypair] seed phrase: 🔒
-[identity-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
-```
-
-The `--ask-seed-phrase` option accepts multiple keypairs. If you wish to use this
-input method for your voting keypair as well you can do the following:
-
-```bash
-solana-validator --ask-seed-phrase identity-keypair voting-keypair --ledger ...
-
-[identity-keypair] seed phrase: 🔒
-[identity-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
-[voting-keypair] seed phrase: 🔒
-[voting-keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
-```
-
-Refer to the following page for a comprehensive guide on running a validator:
-{% page-ref page="../running-validator/README.md" %}
-
-## Delegating Stake
-
-Solana CLI tooling supports secure keypair input for stake delegation. To do so,
-first create a stake account with some SOL. Use the special `ASK` keyword to
-trigger a seed phrase input prompt for the stake account and use
-`--ask-seed-phrase keypair` to securely input the funding keypair.
-
-```bash
-solana create-stake-account ASK 1 SOL --ask-seed-phrase keypair
-
-[stake_account] seed phrase: 🔒
-[stake_account] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
-[keypair] seed phrase: 🔒
-[keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:
-```
-
-Then, to delegate that stake to a validator, use `--ask-seed-phrase keypair` to
-securely input the funding keypair.
-
-```bash
-solana delegate-stake --ask-seed-phrase keypair <STAKE_ACCOUNT_PUBKEY> <VOTE_ACCOUNT_PUBKEY>
-
-[keypair] seed phrase: 🔒
-[keypair] If this seed phrase has an associated passphrase, enter it now. Otherwise, press ENTER to continue:

-# Solana ABI management process
-
-This document proposes the Solana ABI management process. The ABI management
-process is an engineering practice and a supporting technical framework to avoid
-introducing unintended incompatible ABI changes.
-
-# Problem
-
-The Solana ABI (binary interface to the cluster) is currently only defined
-implicitly by the implementation and requires a very careful eye to notice
-breaking changes. This makes it extremely difficult to upgrade the software
-on an existing cluster without rebooting the ledger.
-
-# Requirements and objectives
-
-- Unintended ABI changes can be detected as CI failures mechanically.
-- Newer implementation must be able to process the oldest data (since genesis)
-  once we go mainnet.
-- The objective of this proposal is to protect the ABI while sustaining rather
-  rapid development by opting for a mechanical process rather than a very long
-  human-driven auditing process.
-- Once signed cryptographically, data blob must be identical, so no
-  in-place data format update is possible regardless of inbound and outbound of
-  the online system. Also, considering the sheer volume of transactions we're
-  aiming to handle, retrospective in-place update is undesirable at best.
-
-# Solution
-
-Instead of natural human's eye due-diligence, which should be assumed to fail
-regularly, we need a systematic assurance of not breaking the cluster when
-changing the source code.
-
-For that purpose, we introduce a mechanism of marking every ABI-related things
-in source code (`struct`s, `enum`s) with the new `#[frozen_abi]` attribute. This
-takes hard-coded digest value derived from types of its fields via
-`ser::Serialize`. And the attribute automatically generates a unit test to try
-to detect any unsanctioned changes to the marked ABI-related things.
-
-However, the detection cannot be complete; no matter how hard we statically
-analyze the source code, it's still possible to break ABI. For example, this
-includes not-`derive`d hand-written `ser::Serialize`, underlying library's
-implementation changes (for example `bincode`), CPU architecture differences.
-The detection of these possible ABI incompatibilities is out-of-scope for this
-ABI management.
-
-# Definitions
-
-ABI item/type: various types to be used for serialization, which collectively
-comprises the whole ABI for any system components. For example, those types
-include `struct`s and `enum`s.
-
-ABI item digest: Some fixed hash derived from type information of ABI item's
-fields.
-
-# Example
-
-```patch
-+#[frozen_abi(digest="1c6a53e9")]
- #[derive(Serialize, Default, Deserialize, Debug, PartialEq, Eq, Clone)]
- pub struct Vote {
-     /// A stack of votes starting with the oldest vote
-     pub slots: Vec<Slot>,
-     /// signature of the bank's state at the last slot
-     pub hash: Hash,
- }
-```
-
-# Developer's workflow
-
-To know the digest for new ABI items, developers can add `frozen_abi` with a
-random digest value and run the unit tests and replace it with the correct
-digest from the assertion test error message.
-
-In general, once we add `frozen_abi` and its change is published in the stable
-release channel, its digest should never change. If such a change is needed, we
-should opt for defining a new struct like `FooV1`. And special release flow like
-hard forks should be approached.
-
-# Implementation remarks
-
-We use some degree of macro machinery to automatically generate unit tests
-and calculate a digest from ABI items. This is doable by clever use of
-`serde::Serialize` ([1]) and `any::typename` ([2]). For a precedent for similar
-implementation, `ink` from the Parity Technologies [3] could be informational.

-# Cross-Program Invocation
-
-## Problem
-
-In today's implementation a client can create a transaction that modifies two accounts, each owned by a separate on-chain program:
-
-```text
-let message = Message::new(vec![
-    token_instruction::pay(&alice_pubkey),
-    acme_instruction::launch_missiles(&bob_pubkey),
-]);
-client.send_message(&[&alice_keypair, &bob_keypair], &message);
-```
-
-The current implementation does not, however, allow the `acme` program to conveniently invoke `token` instructions on the client's behalf:
-
-```text
-let message = Message::new(vec![
-    acme_instruction::pay_and_launch_missiles(&alice_pubkey, &bob_pubkey),
-]);
-client.send_message(&[&alice_keypair, &bob_keypair], &message);
-```
-
-Currently, there is no way to create instruction `pay_and_launch_missiles` that executes `token_instruction::pay` from the `acme` program. The workaround is to extend the `acme` program with the implementation of the `token` program, and create `token` accounts with `ACME_PROGRAM_ID`, which the `acme` program is permitted to modify. With that workaround, `acme` can modify token-like accounts created by the `acme` program, but not token accounts created by the `token` program.
-
-## Proposed Solution
-
-The goal of this design is to modify Solana's runtime such that an on-chain program can invoke an instruction from another program.
-
-Given two on-chain programs `token` and `acme`, each implementing instructions `pay()` and `launch_missiles()` respectively, we would ideally like to implement the `acme` module with a call to a function defined in the `token` module:
-
-```text
-use token;
-
-fn launch_missiles(keyed_accounts: &[KeyedAccount]) -> Result<()> {
-    ...
-}
-
-fn pay_and_launch_missiles(keyed_accounts: &[KeyedAccount]) -> Result<()> {
-    token::pay(&keyed_accounts[1..])?;
-
-    launch_missiles(keyed_accounts)?;
-}
-```
-
-The above code would require that the `token` crate be dynamically linked, so that a custom linker could intercept calls and validate accesses to `keyed_accounts`. That is, even though the client intends to modify both `token` and `acme` accounts, only `token` program is permitted to modify the `token` account, and only the `acme` program is permitted to modify the `acme` account.
-
-Backing off from that ideal cross-program call, a slightly more verbose solution is to expose token's existing `process_instruction()` entrypoint to the acme program:
-
-```text
-use token_instruction;
-
-fn launch_missiles(keyed_accounts: &[KeyedAccount]) -> Result<()> {
-    ...
-}
-
-fn pay_and_launch_missiles(keyed_accounts: &[KeyedAccount]) -> Result<()> {
-    let alice_pubkey = keyed_accounts[1].key;
-    let instruction = token_instruction::pay(&alice_pubkey);
-    process_instruction(&instruction)?;
-
-    launch_missiles(keyed_accounts)?;
-}
-```
-
-where `process_instruction()` is built into Solana's runtime and responsible for routing the given instruction to the `token` program via the instruction's `program_id` field. Before invoking `pay()`, the runtime must also ensure that `acme` didn't modify any accounts owned by `token`. It does this by calling `runtime::verify_account_changes()` and then afterward updating all the `pre_*` variables to tentatively commit `acme`'s account modifications. After `pay()` completes, the runtime must again ensure that `token` didn't modify any accounts owned by `acme`. It should call `verify_account_changes()` again, but this time with the `token` program ID. Lastly, after `pay_and_launch_missiles()` completes, the runtime must call `verify_account_changes()` one more time, where it normally would, but using all updated `pre_*` variables. If executing `pay_and_launch_missiles()` up to `pay()` made no invalid account changes, `pay()` made no invalid changes, and executing from `pay()` until `pay_and_launch_missiles()` returns made no invalid changes, then the runtime can transitively assume `pay_and_launch_missiles()` as whole made no invalid account changes, and therefore commit all account modifications.
-
-### Setting `KeyedAccount.is_signer`
-
-When `process_instruction()` is invoked, the runtime must create a new `KeyedAccounts` parameter using the signatures from the _original_ transaction data. Since the `token` program is immutable and existed on-chain prior to the `acme` program, the runtime can safely treat the transaction signature as a signature of a transaction with a `token` instruction. When the runtime sees the given instruction references `alice_pubkey`, it looks up the key in the transaction to see if that key corresponds to a transaction signature. In this case it does and so sets `KeyedAccount.is_signer`, thereby authorizing the `token` program to modify Alice's account.
-
