+//! 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!
