+# Guidelines
+
+## MR/Commit Messages
+
+NOTE: Not necessary to follow this until V1.0 release.
+
+Use a [Conventional Commit](https://www.conventionalcommits.org/en/v1.0.0/) format when creating MR's. For example:
+
+```
+feat(Primitives): Add Transaction Primitive
+```
+
+... or to indicate a breaking change (using `!`):
+
+```
+chore!: Drop support for Node 16
+```
+
+This will ensure that we can automatically generate correct [Semantic Versions](https://semver.org/) and changelogs between releases (using Lerna).
+
+A table of common prefixes (conventions) is below:
+
+| Change   | Description                                                                                                 |
+|----------|-------------------------------------------------------------------------------------------------------------|
+| feat     | A new feature                                                                                               |
+| fix      | A bug fix                                                                                                   |
+| docs     | Documentation only changes                                                                                  |
+| style    | Changes that do not affect the meaning of the code (formatting)                                             |
+| refactor | A code change that neither fixes a bug nor adds a feature                                                   |
+| perf     | A code change that improves performance                                                                     |
+| test     | Adding missing tests or correct existing tests                                                              |
+| build    | Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)         |
+| ci       | Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs) |
+| chore    | Other changes that don't modify src or test files                                                           |
+| revert   | Reverts a previous commit                                                                                   |

+## Patterns
+
+### Dependency Injection
+
+We use Dependency Injection (DI) for several key reasons:
+
+- Improved testability: Dependencies can be easily mocked during unit tests
+- Reduced coupling: Classes depend on abstractions rather than concrete implementations
+- Greater flexibility: Implementations can be swapped without modifying dependent classes
+- Clearer dependencies: Constructor signatures explicitly document required dependencies
+- Easier refactoring: Component relationships are clearly defined
+- Simpler dependency management: Easier control over resource initialization and lifecycle
+
+Try not to over-abstract, but if there is already a Base Class (or interface) available, always try to use that (via dependency injection) in favor of a concrete implementation.
+
+For example:
+
+```ts
+class SomeClass {
+  protected blockchain: BaseBlockchain;
+  protected store: BaseStore;
+
+  constructor(
+    //
+    dependencies: {
+      blockchain: BaseBlockchain,
+      store: BaseStore,
+    }
+  ) {
+    this.blockchain = dependencies.blockchain;
+    this.store = dependencies.store;
+  }
+}
+```
+
+### Factory Patterns
+
+When creating classes, create static `from(...)` (or `fromSpecificThing(...)`) methods.
+
+*Semantically, think of "from" as meaning "instantiate from": This is more succinct than a `create` factory method which, if we have multiple ways of instantiation, can become verbose. E.g. `PrivateKey.fromWIF()` as opposed to `PrivateKey.createFromWIF()`. It also allows us to differentiate between actually "creating" something (e.g. a `Filesystem.createFile(...)`) versus "instantiating" a representation of a "thing".*
+
+In Javascript, a `constructor` cannot be asynchronous and we want to ensure that we can `await` class instantiation to mitigate against stateful errors.
+
+For example:
+
+```ts
+class SomeClass {
+  // Static "from" factory method.
+  // NOTE: The below args are shorthand for using the same arguments as the constructor.
+  static async from(...args: ConstructorParameters<typeof SomeClass>) {
+    // Create the instance.
+    const someClass = new SomeClass(...args);
+
+    // Execute the asynchronous initialization function.
+    await someClass.start();
+
+    // Return the instance.
+    return someClass;
+  }
+}
+```
+
+Although this isn't always necessary (i.e. not all instantiations need to be `async`), it keeps instantiation of classes consistent.
+
+### Validations
+
+Check types with TypeScript - Runtime type-checking is a code smell. If the function accepts a string, assume it's been given a string. TypeScript definitions should expose improperly called functions to the developer at compile time, don't re-implement it at runtime.
+
+There are a few exceptions to this:
+
+- If TypeScript's lack of dependant types makes validating certain properties of a type (e.g. the length of a Uint8Array), then runtime type-checking should be used to detect and return errors.
+- If we are working with a network (remote/untrusted) payload, Type Validation should be done with [Zod](https://www.npmjs.com/package/zod).
+
+An example of working with Zod:
+
+```ts
+// Define a schema so that we can validate the payload.
+export const SomeRemotePayload = z.object({
+  publicKey: z.string(),
+  action: z.enum(['set', 'delete', 'clear']),
+  key: z.string(),
+  value: z.string(),
+  timestamp: z.number(),
+});
+
+// Run Zod's validation against this payload.
+// NOTE: This will throw if it fails.
+const parsedPayload = SomeRemotePayload.parse(rawPayload);
+
+// (Optional) If this type is needed elsewhere, we can infer it from Zod and export it.
+export type StoreRemoteHTTPEvent = z.infer<typeof StoreRemoteHTTPEventSchema>;
+```
+

+ * Implements an event sourcing pattern for managing application state.
+ *
+ * Event sourcing is an architectural pattern where:
+ * - All changes to application state are stored as a sequence of immutable events
+ * - The current state is derived by replaying these events in chronological order
+ * - Events serve as both the source of truth and a complete audit log
+ *
+ * This implementation provides:
+ * - Eventually consistent state across distributed systems
+ * - Conflict resolution through configurable policies
+ * - Point-in-time state reconstruction capability
+ * - Separation between event storage and derived state (snapshot)
+ *
+ * Events (Activities) in this system:
+ * - Have a unique identifier
+ * - Include a timestamp for ordering
+ * - Contain a type and associated value
+ * - Are processed according to registered type-specific policies
+ *
+ * @example
+ * ```typescript
+ * // Create Activities manager with a store implementation
+ * const activities = new Activities(new MyBaseStore());
+ *
+ * // Register a custom policy for wallet name conflicts
+ * activities.registerPolicy('WalletName', (existing, newActivity) => {
+ *   // Keep the most recent wallet name
+ *   return existing?.timestamp! > newActivity.timestamp! ? existing : newActivity;
+ * });
+ *
+ * // Initialize by compiling snapshot from stored events
