-# Building
+# About
+This repository contains Jito's fork of the Solana validator.
 
-## **1. Install rustc, cargo and rustfmt.**
-
-```bash
-$ curl https://sh.rustup.rs -sSf | sh
-$ source $HOME/.cargo/env
-$ rustup component add rustfmt
-```
-
-When building the master branch, please make sure you are using the latest stable rust version by running:
-
-```bash
-$ rustup update
-```
-
-When building a specific release branch, you should check the rust version in `ci/rust-version.sh` and if necessary, install that version by running:
-```bash
-$ rustup install VERSION
-```
-Note that if this is not the latest rust version on your machine, cargo commands may require an [override](https://rust-lang.github.io/rustup/overrides.html) in order to use the correct version.
-
-On Linux systems you may need to install libssl-dev, pkg-config, zlib1g-dev, protobuf etc.
-
-On Ubuntu:
-```bash
-$ sudo apt-get update
-$ sudo apt-get install libssl-dev libudev-dev pkg-config zlib1g-dev llvm clang cmake make libprotobuf-dev protobuf-compiler
-```
-
-On Fedora:
-```bash
-$ sudo dnf install openssl-devel systemd-devel pkg-config zlib-devel llvm clang cmake make protobuf-devel protobuf-compiler perl-core
-```
-
-## **2. Download the source code.**
-
-```bash
-$ git clone https://github.com/solana-labs/solana.git
-$ cd solana
-```
-
-## **3. Build.**
-
-```bash
-$ ./cargo build
-```
-
-# Testing
-
-**Run the test suite:**
-
-```bash
-$ ./cargo test
-```
-
-### Starting a local testnet
-Start your own testnet locally, instructions are in the [online docs](https://docs.solana.com/cluster/bench-tps).
-
-### Accessing the remote development cluster
-* `devnet` - stable public cluster for development accessible via
-devnet.solana.com. Runs 24/7. Learn more about the [public clusters](https://docs.solana.com/clusters)
-
-# Benchmarking
-
-First, install the nightly build of rustc. `cargo bench` requires the use of the
-unstable features only available in the nightly build.
-
-```bash
-$ rustup install nightly
-```
-
-Run the benchmarks:
-
-```bash
-$ cargo +nightly bench
-```
-
-# Release Process
-
-The release process for this project is described [here](RELEASE.md).
-
-# Code coverage
-
-To generate code coverage statistics:
-
-```bash
-$ scripts/coverage.sh
-$ open target/cov/lcov-local/index.html
-```
-
-Why coverage? While most see coverage as a code quality metric, we see it primarily as a developer
-productivity metric. When a developer makes a change to the codebase, presumably it's a *solution* to
-some problem.  Our unit-test suite is how we encode the set of *problems* the codebase solves. Running
-the test suite should indicate that your change didn't *infringe* on anyone else's solutions. Adding a
-test *protects* your solution from future changes. Say you don't understand why a line of code exists,
-try deleting it and running the unit-tests. The nearest test failure should tell you what problem
-was solved by that code. If no test fails, go ahead and submit a Pull Request that asks, "what
-problem is solved by this code?" On the other hand, if a test does fail and you can think of a
-better way to solve the same problem, a Pull Request with your solution would most certainly be
-welcome! Likewise, if rewriting a test can better communicate what code it's protecting, please
-send us that patch!

-
-<a name="reporting"></a>
-## Reporting security problems in the Solana Labs Validator Client
-
-**DO NOT CREATE A GITHUB ISSUE** to report a security problem.
-
-Instead please use this [Report a Vulnerability](https://github.com/solana-labs/solana/security/advisories/new) link.
-Provide a helpful title, detailed description of the vulnerability and an exploit
-proof-of-concept. Speculative submissions without proof-of-concept will be closed
-with no further consideration.
-
-If you haven't done so already, please **enable two-factor auth** in your GitHub account.
-
-Expect a response as fast as possible in the advisory, typically within 72 hours.
-
---
-
-If you do not receive a response in the advisory, send an email to
-security@solanalabs.com with the full URL of the advisory you have created.  DO NOT
-include attachments or provide detail sufficient for exploitation regarding the
-security issue in this email. **Only provide such details in the advisory**.
-
-If you do not receive a response from security@solanalabs.com please followup with
-the team directly. You can do this in the `#core-technology` channel of the
-[Solana Tech discord server](https://solana.com/discord), by pinging the `Solana Labs`
-role in the channel and referencing the fact that you submitted a security problem.
-
-<a name="process"></a>
-## Incident Response Process
-
-In case an incident is discovered or reported, the following process will be
-followed to contain, respond and remediate:
-
-### 1. Accept the new report
-In response a newly reported security problem, a member of the
-`solana-labs/admins` group will accept the report to turn it into a draft
-advisory.  The `solana-labs/security-incident-response` group should be added to
-the draft security advisory, and create a private fork of the repository (grey
-button towards the bottom of the page) if necessary.
-
-If the advisory is the result of an audit finding, follow the same process as above but add the auditor's github user(s) and begin the title with "[Audit]".
-
-If the report is out of scope, a member of the `solana-labs/admins` group will
-comment as such and then close the report.
-
-### 2. Triage
-Within the draft security advisory, discuss and determine the severity of the issue. If necessary, members of the solana-labs/security-incident-response group may add other github users to the advisory to assist.
-If it is determined that this not a critical network issue then the advisory should be closed and if more follow-up is required a normal Solana public github issue should be created.
-
-### 3. Prepare Fixes
-For the affected branches, typically all three (edge, beta and stable), prepare a fix for the issue and push them to the corresponding branch in the private repository associated with the draft security advisory.
-There is no CI available in the private repository so you must build from source and manually verify fixes.
-Code review from the reporter is ideal, as well as from multiple members of the core development team.
-
-### 4. Notify Security Group Validators
-Once an ETA is available for the fix, a member of the solana-labs/security-incident-response group should notify the validators so they can prepare for an update using the "Solana Red Alert" notification system.
-The teams are all over the world and it's critical to provide actionable information at the right time. Don't be the person that wakes everybody up at 2am when a fix won't be available for hours.
-
-### 5. Ship the patch
-Once the fix is accepted, a member of the solana-labs/security-incident-response group should prepare a single patch file for each affected branch. The commit title for the patch should only contain the advisory id, and not disclose any further details about the incident.
-Copy the patches to https://release.solana.com/ under a subdirectory named after the advisory id (example: https://release.solana.com/GHSA-hx59-f5g4-jghh/v1.4.patch). Contact a member of the solana-labs/admins group if you require access to release.solana.com
-Using the "Solana Red Alert" channel:
-    a) Notify validators that there's an issue and a patch will be provided in X minutes
-    b) If X minutes expires and there's no patch, notify of the delay and provide a new ETA
-    c) Provide links to patches of https://release.solana.com/ for each affected branch
-Validators can be expected to build the patch from source against the latest release for the affected branch.
-Since the software version will not change after the patch is applied, request that each validator notify in the existing channel once they've updated. Manually monitor the roll out until a sufficient amount of stake has updated - typically at least 33.3% or 66.6% depending on the issue.
-
-### 6. Public Disclosure and Release
-Once the fix has been deployed to the security group validators, the patches from the security advisory may be merged into the main source repository. A new official release for each affected branch should be shipped and all validators requested to upgrade as quickly as possible.
-
-### 7. Security Advisory Bounty Accounting and Cleanup
-If this issue is [eligible](#eligibility) for a bounty, prefix the title of the
-security advisory with one of the following, depending on the severity:
-- [Bounty Category: Critical: Loss of Funds]
-- [Bounty Category: Critical: Consensus / Safety Violations]
-- [Bounty Category: Critical: Liveness / Loss of Availability]
-- [Bounty Category: Critical: DoS Attacks]
-- [Bounty Category: Supply Chain Attacks]
-- [Bounty Category: RPC]
-
-Confirm with the reporter that they agree with the severity assessment, and discuss as required to reach a conclusion.
-
-We currently do not use the Github workflow to publish security advisories. Once the issue and fix have been disclosed, and a bounty category is assessed if appropriate, the GitHub security advisory is no longer needed and can be closed.

-## Security Bug Bounties
-At its sole discretion, the Solana Foundation may offer a bounty for
-[valid reports](#reporting) of critical Solana vulnerabilities. Please see below
-for more details. The submitter is not required to provide a
-mitigation to qualify.
-
-#### Loss of Funds:
-$2,000,000 USD in locked SOL tokens (locked for 12 months)
-* Theft of funds without users signature from any account
-* Theft of funds without users interaction in system, token, stake, vote programs
-* Theft of funds that requires users signature - creating a vote program that drains the delegated stakes.
-
-#### Consensus/Safety Violations:
-$1,000,000 USD in locked SOL tokens (locked for 12 months)
-* Consensus safety violation
-* Tricking a validator to accept an optimistic confirmation or rooted slot without a double vote, etc.
-
-#### Liveness / Loss of Availability:
-$400,000 USD in locked SOL tokens (locked for 12 months)
-* Whereby consensus halts and requires human intervention
-* Eclipse attacks,
-* Remote attacks that partition the network,
-
-#### DoS Attacks:
-$100,000 USD in locked SOL tokens (locked for 12 months)
-* Remote resource exaustion via Non-RPC protocols
-
-#### Supply Chain Attacks:
-$100,000 USD in locked SOL tokens (locked for 12 months)
-* Non-social attacks against source code change management, automated testing, release build, release publication and release hosting infrastructure of the monorepo.
-
-#### RPC DoS/Crashes:
-$5,000 USD in locked SOL tokens (locked for 12 months)
-* RPC attacks
-
-### Out of Scope:
-The following components are out of scope for the bounty program
-* Metrics: `/metrics` in the monorepo as well as https://metrics.solana.com
-* Any encrypted credentials, auth tokens, etc. checked into the repo
-* Bugs in dependencies. Please take them upstream!
-* Attacks that require social engineering
-* Any undeveloped automated tooling (scanners, etc) results. (OK with developed PoC)
-* Any asset whose source code does not exist in this repository (including, but not limited
-to, any and all web properties not explicitly listed on this page)
-
-### Eligibility:
-* Submissions _MUST_ include an exploit proof-of-concept to be considered eligible
-* The participant submitting the bug report shall follow the process outlined within this document
-* Valid exploits can be eligible even if they are not successfully executed on a public cluster
-* Multiple submissions for the same class of exploit are still eligible for compensation, though may be compensated at a lower rate, however these will be assessed on a case-by-case basis
-* Participants must complete KYC and sign the participation agreement here when the registrations are open https://solana.foundation/kyc. Security exploits will still be assessed and open for submission at all times. This needs only be done prior to distribution of tokens.
-
-### Duplicate Reports
-Compensation for duplicative reports will be split among reporters with first to report taking priority using the following equation
-```
-R: total reports
-ri: report priority
-bi: bounty share
-
-bi = 2 ^ (R - ri) / ((2^R) - 1)
-```
-#### Bounty Split Examples
-| total reports | priority | share  |   | total reports | priority | share  |   | total reports | priority | share  |
-| ------------- | -------- | -----: | - | ------------- | -------- | -----: | - | ------------- | -------- | -----: |

-| 4             | 3        | 13.33% |   | 3             | 2        | 28.57% |   | 5             | 5        |  3.23% |
-| 4             | 4        |  6.67% |   | 3             | 3        | 14.29% |   |               |          |        |
-
-### Payment of Bug Bounties:
-* Bounties are currently awarded on a rolling/weekly basis and paid out within 30 days upon receipt of an invoice.
-* The SOL/USD conversion rate used for payments is the market price of SOL (denominated in USD) at the end of the day the invoice is submitted by the researcher.
-* The reference for this price is the Closing Price given by Coingecko.com on that date given here: https://www.coingecko.com/en/coins/solana/historical_data/usd#panel
-* Bug bounties that are paid out in SOL are paid to stake accounts with a lockup expiring 12 months from the date of delivery of SOL.

+//! Handles pre-locking bundle accounts so that accounts bundles touch can be reserved ahead
+// of time for execution. Also, ensures that ALL accounts mentioned across a bundle are locked
+// to avoid race conditions between BundleStage and BankingStage.
+//
+// For instance, imagine a bundle with three transactions and the set of accounts for each transaction
+// is: {{A, B}, {B, C}, {C, D}}. We need to lock A, B, and C even though only one is executed at a time.
+// Imagine BundleStage is in the middle of processing {C, D} and we didn't have a lock on accounts {A, B, C}.
+// In this situation, there's a chance that BankingStage can process a transaction containing A or B
+// and commit the results before the bundle completes. By the time the bundle commits the new account
+// state for {A, B, C}, A and B would be incorrect and the entries containing the bundle would be
+// replayed improperly and that leader would have produced an invalid block.

+# Tip Distributor
+This library and collection of binaries are responsible for generating and uploading merkle roots to the on-chain 
+tip-distribution program found [here](https://github.com/jito-foundation/jito-programs/blob/submodule/tip-payment/programs/tip-distribution/src/lib.rs).
+
+## Background
+Each individual validator is assigned a new PDA per epoch where their share of tips, in lamports, will be stored. 
+At the end of the epoch it's expected that validators take a commission and then distribute the rest of the funds
+to their delegators such that delegators receive rewards proportional to their respective delegations. The distribution
+mechanism is via merkle proofs similar to how airdrops work.
+
+The merkle roots are calculated off-chain and uploaded to the validator's **TipDistributionAccount** PDA. Validators may
+elect an account to upload the merkle roots on their behalf. Once uploaded, users can invoke the **claim** instruction
+and receive the rewards they're entitled to. Once all funds are claimed by users the validator can close the account and
+refunded the rent.
+
+## Scripts
+
+### stake-meta-generator
+
+This script generates a JSON file identifying individual stake delegations to a validator, along with amount of lamports 
+in each validator's **TipDistributionAccount**. All validators will be contained in the JSON list, regardless of whether 
+the validator is a participant in the system; participant being indicative of running the jito-solana client to accept tips 
+having initialized a **TipDistributionAccount** PDA account for the epoch.
+
+One edge case that we've taken into account is the last validator in an epoch N receives tips but those tips don't get transferred
+out into the PDA until some slot in epoch N + 1. Due to this we cannot rely on the bank's state at epoch N for lamports amount
+in the PDAs. We use the bank solely to take a snapshot of delegations, but an RPC node to fetch the PDA lamports for more up-to-date data.
+
+### merkle-root-generator
+This script accepts a path to the above JSON file as one of its arguments, and generates a merkle-root into a JSON file.
+
+### merkle-root-uploader
+Uploads the root on-chain.
+
+### claim-mev-tips
+This reads the file outputted by `merkle-root-generator` and finds all eligible accounts to receive mev tips. Transactions
+are created and sent to the RPC server.
+
+
+## How it works?
+In order to use this library as the merkle root creator one must follow the following steps:
+1. Download a ledger snapshot containing the slot of interest, i.e. the last slot in an epoch. The Solana foundation has snapshots that can be found [here](https://console.cloud.google.com/storage/browser/mainnet-beta-ledger-us-ny5).
+2. Download the snapshot onto your worker machine (where this script will run).
+3. Run `solana-ledger-tool -l ${PATH_TO_LEDGER} create-snapshot ${YOUR_SLOT} ${WHERE_TO_CREATE_SNAPSHOT}`
+   1. The snapshot created at `${WHERE_TO_CREATE_SNAPSHOT}` will have the highest slot of `${YOUR_SLOT}`, assuming you downloaded the correct snapshot.
+4. Run `stake-meta-generator --ledger-path ${WHERE_TO_CREATE_SNAPSHOT} --tip-distribution-program-id ${PUBKEY} --out-path ${JSON_OUT_PATH} --snapshot-slot ${SLOT} --rpc-url ${URL}`
+   1. Note: `${WHERE_TO_CREATE_SNAPSHOT}` must be the same in steps 3 & 4.
+5. Run `merkle-root-generator --stake-meta-coll-path ${STAKE_META_COLLECTION_JSON} --rpc-url ${URL} --out-path ${MERKLE_ROOT_PATH}`
+6. Run `merkle-root-uploader --out-path ${MERKLE_ROOT_PATH} --keypair-path ${KEYPAIR_PATH} --rpc-url ${URL} --tip-distribution-program-id ${PROGRAM_ID}`
+7. Run `solana-claim-mev-tips --merkle-trees-path /solana/ledger/autosnapshot/merkle-tree-221615999.json --rpc-url ${URL} --tip-distribution-program-id ${PROGRAM_ID} --keypair-path ${KEYPAIR_PATH}`
+
+Voila!
