+# NEAR Lake Primitive Types
+
+This article contains the primitive types used by the [NEAR Lake Framework package](https://www.npmjs.com/package/@near-lake/framework). These types are used to define the data structures used by the framework as well as provide some popular helper functions.
+
+## `Block`
+
+:::info Important Notes on `Block`
+
+- All the entities located on different shards were merged into one single list without differentiation.
+- `Block` is not the fairest name for this structure either. NEAR Protocol is a sharded blockchain, so its block is actually an ephemeral structure that represents a collection of real blocks called chunks in NEAR Protocol.
+
+:::
+
+### `Block` Structure Definition
+
+The `Block` type is used to represent a block in the NEAR Lake Framework. It is comprised by the following structure:
+
+```ts
+export class Block {
+    constructor(
+        readonly streamerMessage: StreamerMessage,
+        private executedReceipts: Receipt[],
+        readonly postponedReceipts: Receipt[],
+        readonly transactions: Transaction[],
+        private _actions: Map<string, Action>,
+        private _events: Map<string, Event[]>,
+        private _stateChanges: StateChange[]) { 
+
+        }
+    ... // helper methods and getters omitted for brevity
+}
+```
+
+#### `streamerMessage`
+
+Low-level structure for backward compatibility. As implemented in previous versions of [`near-lake-framework`](https://www.npmjs.com/package/near-lake-framework). 
+
+#### `postponedReceipts`
+
+Receipts included on the chain but not executed yet marked as “postponed”: they are represented by the same structure `Receipt` (see the corresponding section in this doc for more details).
+
+#### `transactions`
+
+List of included `Transactions`, converted into `Receipts`.
+
+:::info Heads up!
+
+**Note:**  You might want to know about `Transactions` to know where the action chain has begun. Unlike Ethereum, where a Transaction contains everything you may want to know about a particular interaction on  the Ethereum blockchain, Near Protocol because of its asynchronous nature converts a `Transaction` into a `Receipt` before executing it. Thus, On NEAR, `Receipts` are more important for figuring out what happened on-chain as a result of a Transaction signed by a user. Read more about [Transactions on Near](https://nomicon.io/RuntimeSpec/Transactions) here.

+
+### `Block` Helper Methods
+
+```ts
+export class Block {
+    ... // constructor omitted for brevity
+    get blockHash(): string {}
+    get prevBlockHash(): string {}
+    get blockHeight(): number {}
+
+    header(): BlockHeader {}
+    receipts(): Receipt[] {}
+    actions(): Action[] {}
+    events(): Event[] {}
+    stateChanges(): StateChange[] {}
+
+    actionByReceiptId(receipt_id: string): Action | undefined {}
+    eventsByReceiptId(receipt_id: string): Event[] {}
+    eventsByAccountId(account_id: string): Event[] {}
+
+    private buildActionsHashmap() {}
+    private buildEventsHashmap(): Map<string, Event[]> {}
+
+    static fromStreamerMessage(streamerMessage: StreamerMessage): Block {}
+}
+```
+
+#### `blockHash`
+
+Returns the block hash. A shortcut to get the data from the block header.
+
+#### `prevBlockHash`
+
+Returns the previous block hash. A shortcut to get the data from the block header.
+
+#### `blockHeight`
+
+Returns the block height. A shortcut to get the data from the block header.
+
+#### `header(): BlockHeader`
+
+Returns a `BlockHeader` structure of the block
+
+See `BlockHeader` structure sections for details.
+
+#### `receipts(): Receipt[]`
+
+Returns a slice of `Receipts` executed in the block.
+
+Basically is a getter for the `executedReceipts` field.
+
+#### `actions(): Action[]`
+
+Returns an Array of `Actions` executed in the block.
+
+#### `events(): Event[]`
+
+Returns `Events` emitted in the block.
+
+#### `stateChanges(): StateChange[]`
+
+Returns an Array of `StateChange` occurred in the block.
+
+#### `actionByReceiptId(receipt_id: string): Action | undefined`
+
+Returns `Action`s of the provided `receipt_id` from the block if any. Returns `undefined` if there is no corresponding `Action`.
+
+This method uses the internal `Block` `action` field which is empty by default and will be filled with the block’s actions on the first call to optimize memory usage.
+
+The result is either `Action | undefined` since there might be a request for an `Action` by `receipt_id` from another block, in which case this method will be unable to find the `Action` in the current block. In the other case, the request might be for an `Action` for a `receipt_id` that belongs to a `DataReceipt` where an action does not exist.
+
+#### `eventsByReceiptId(receipt_id: string): Event[]`
+
+Returns an Array of Events emitted by `ExecutionOutcome` for the given `receipt_id`. There might be more than one `Event` for the `Receipt` or there might be none of them. In the latter case, this method returns an empty Array.
+
+#### `eventsByAccountId(account_id: string): Event[]`
+
+Returns an Array of Events emitted by `ExecutionOutcome` for the given `account_id`. There might be more than one `Event` for the `Receipt` or there might be none of them. In the latter case, this method returns an empty Array.
+
+---
+
+## `BlockHeader`
+
+Replacement for `BlockHeaderView` from `near-primitives`. Shrunken and simplified. 
+
+:::note
+The original `BlockHeaderView` is still accessible via the `.streamerMessage` attribute.
+:::
+
+### `BlockHeader` Structure Definition
+
+```ts
+export class BlockHeader {
+    constructor(
+        readonly height: number,
+        readonly hash: string,
+        readonly prevHash: string,
+        readonly author: string,
+        readonly timestampNanosec: string,
+        readonly epochId: string,
+        readonly nextEpochId: string,
+        readonly gasPrice: string,
+        readonly totalSupply: string,
+        readonly latestProtocolVersion: number,
+        readonly randomValue: string,
+        readonly chunksIncluded: number,
+        readonly validatorProposals: ValidatorStakeView[]) { 
+        }
+    ... // helper method omitted for brevity
+}
+```
+
+---
+
+## `Receipt`
+
+This field is a simplified representation of the `ReceiptView` structure from `near-primitives`.
+
+### `Receipt` Structure Definition
+
+```ts
+export class Receipt implements Events {
+  constructor(
+    readonly receiptKind: ReceiptKind, 
+    readonly receiptId: string, 
+    readonly receiverId: string, 
+    readonly predecessorId: string, 
+    readonly status: ExecutionStatus, 
+    readonly executionOutcomeId?: string | undefined, 
+    readonly logs: string[] = []) {
+    }
+  ... // helper methods omitted for brevity
+}
+```
+
+### `Receipt` Fields
+
+#### `receiptKind`
+
+Defined the type of the `Receipt`: `Action` or `Data` representing the `ActionReceipt` and `DataReceipt`.
+
+#### `receiptId`
+
+The ID of the `Receipt` of the `CryptoHash` type.
+
+#### `receiverId`
+
+The receiver account id of the `Receipt`.
+
+#### `predecessorId`
+
+The predecessor account id of the `Receipt`.
+
+#### `status`
+
+Represents the status of `ExecutionOutcome` of the `Receipt`.
+
+See the `ExecutionStatus` enum section for the details.
+
+#### `executionOutcomeId`
+
+The id of the `ExecutionOutcome` for the `Receipt`. Returns `null` if the `Receipt` isn’t executed yet and has a postponed status.
+
+#### `logs`
+
+The original logs of the corresponding `ExecutionOutcome` of the `Receipt`.
+
+Note: not all of the logs might be parsed as JSON Events (`Events`).
+
+### `Receipt` Helper Methods
+
+```ts
+export class Receipt {
+    ... // constructor omitted for brevity
+    get events(): Event[] {}
+
+    static fromOutcomeWithReceipt(outcomeWithReceipt: OutcomeWithReceipt): Receipt {}
+}
+```
+
+#### `Receipt.events(): Events[]`
+
+Returns an Array of `Events` for the `Receipt`, if any. This might be empty if the `logs` field is empty or doesn’t contain JSON Events compatible log records.
+
+---
+
+## `Event`
+
+This structure is an ephemeral entity to provide access to the [Events Standard](https://github.com/near/NEPs/blob/master/neps/nep-0297.md) structure and keep data about the related `Receipt` for convenience.
+
+### Interface for Capturing Data About an Event in `handleStreamerMessage()`
+
+The interface to capture data about an event has the following arguments:
+
+- `standard`: name of standard, e.g. nep171
+- `version`: e.g. 1.0.0
+- `event`: type of the event, e.g. nft_mint
+- `data`: associate event data. Strictly typed for each set {standard, version, event} inside corresponding NEP
+
+### `Event` Structure Definition
+
+```ts
+export class Event {
+    constructor(
+      readonly relatedReceiptId: string, 
+      readonly rawEvent: RawEvent) {
+      }
+    ... // helper methods omitted for brevity
+}
+```
+
+### `Event` Methods
+
+```ts
+export class Event {
+    ... // constructor omitted for brevity
+    static fromLog(log: string): Event {}
+}
+```
+
+---
+
+## `Transaction`
+
+A representation of the `IndexerTransactionWithOutcome` from `near-indexer-primitives` which is an ephemeral structure combining `SignedTransactionView` from `near-primitives` and `IndexerExecutionOutcomeWithOptionalReceipt` from `near-indexer-primitives`.
+
+This structure is very similar to `Receipt`. Unlike `Receipt`, a `Transaction` has a few additional fields like `signerId`, `signature`, and `operations`.
+
+### `Transaction` Structure Definition
+
+```ts
+export class Transaction {
+    constructor(
+      readonly transactionHash: string, 
+      readonly signerId: string, 
+      readonly signerPublicKey: string, 
+      readonly signature: string, 
+      readonly receiverId: string, 
+      readonly status: ExecutionStatus, 
+      readonly executionOutcomeId: string, 
+      readonly operations: Operation[]) { 
+      }
+}
+```
+
+#### `Transaction.transactionHash`
+
+Returns the hash of the `Transaction` in `CryptoHash`.
+
+#### `Transaction.signerId`
+
+Returns the signer account id of the `Transaction`.
+
+#### `Transaction.signerPublicKey`
+
+Returns the `PublicKey` of the signer of the `Transaction`.
+
+#### `Transaction.signature`
+
+Returns the `Signature` the `Transaction` was signed with.
+
+#### `Transaction.receiverId`
+
+Returns the receiver account id of the `Transaction`.
+
+#### `Transaction.status`
+
+Returns the status of the `Transaction` as `ExecutionStatus`.
+
+#### `Transaction.executionOutcomeId`
+
+Returns the id of the `ExecutionOutcome` for the `Transaction`.
+
+#### `Transaction.operations`
+
+Returns an Array of `Operation` for the `Transaction`.
+
+---
+
+## `StateChange`
+
+This structure is almost an identical copy of the `StateChangeWithCauseView` from `near-primitives` with a propagated additional field `affectedAccountId`.
+
+### `StateChange` Structure Definition
+
+```ts
+export class StateChange {
+    constructor(
+      readonly cause: StateChangeCause, 
+      readonly value: StateChangeValue
+    ) {}
+
+    get affectedAccountId(): string {}
+
+    static fromStateChangeView(stateChangeView: StateChangeWithCauseView) {}
+}
+```
+
+#### `StateChange.cause`
+
+Returns the `cause` of the `StateChange`.
+
+#### `StateChange.value`
+
+Returns the `value` of the `StateChange`.
+
+#### `StateChange.affectedAccountId(): string`
+
+Returns the account id of the `StateChange`.
+
+#### `StateChange.fromStateChangeView(stateChangeView: StateChangeWithCauseView): StateChange`
+
+Returns the `StateChange` from the `StateChangeWithCauseView`. Created for backward compatibility.
