API-CHANGELOG.md

@@ -6,85 +6,90 @@ For info about how [API versioning](https://xrpl.org/request-formatting.html#api
 
 The API version controls the API behavior you see. This includes what properties you see in responses, what parameters you're permitted to send in requests, and so on. You specify the API version in each of your requests. When a breaking change is introduced to the `rippled` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.
 
-The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
-
 For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.
 
-## API Version 3 (Beta)
-
-API version 3 is currently a beta API. It requires enabling `[beta_rpc_api]` in the rippled configuration to use. See [API-VERSION-3.md](API-VERSION-3.md) for the full list of changes in API version 3.
-
 ## API Version 2
 
-API version 2 is available in `rippled` version 2.0.0 and later. See [API-VERSION-2.md](API-VERSION-2.md) for the full list of changes in API version 2.
+API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
+
+#### Removed methods
+
+In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
+
+- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
+- `ledger_header` - Instead, use the `ledger` method.
+
+#### Modifications to JSON transaction element in V2
+
+In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
+This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
+
+- JSON transaction element is named `tx_json`
+- Binary transaction element is named `tx_blob`
+- JSON transaction metadata element is named `meta`
+- Binary transaction metadata element is named `meta_blob`
+
+Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
+
+- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
+- `ledger_index` - Ledger index (only set on validated ledgers)
+- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
+- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
+- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
+
+This change affects the following methods:
+
+- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
+- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
+- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
+
+#### Modification to `Payment` transaction JSON schema
+
+When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
+
+- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
+  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
+  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
+  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
+  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
+
+#### Modifications to account_info response
+
+- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) (https://github.com/XRPLF/rippled/pull/3770)
+- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
+  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
+
+#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
+
+- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
+  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
+- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
+  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
+- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
+
+#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
+
+- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)

-- For the `ledger_data` method, when all entries are filtered out, the `state` field of the response is now an empty list (in other words, an empty array, `[]`). (Previously, it would return `null`.) While this is technically a breaking change, the new behavior is consistent with the documentation, so this is considered only a bug fix.

   - There is a new account deletion restriction: an account can only be deleted if `FirstNFTSequence` + `MintedNFTokens` + `256` is less than the current ledger sequence.
   - This is potentially a breaking change if clients have logic for determining whether an account can be deleted.
 - NetworkID

-# API Version 2
-
-API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
-
-For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
-
-## Removed methods
-
-In API version 2, the following deprecated methods are no longer available: ([#4759](https://github.com/XRPLF/rippled/pull/4759))
-
-- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
-- `ledger_header` - Instead, use the `ledger` method.
-
-## Modifications to JSON transaction element in API version 2
-
-In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. ([#4775](https://github.com/XRPLF/rippled/pull/4775))
-This helps to unify the JSON serialization format of transactions. ([clio#722](https://github.com/XRPLF/clio/issues/722), [#4727](https://github.com/XRPLF/rippled/issues/4727))
-
-- JSON transaction element is named `tx_json`
-- Binary transaction element is named `tx_blob`
-- JSON transaction metadata element is named `meta`
-- Binary transaction metadata element is named `meta_blob`
-
-Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
-
-- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
-- `ledger_index` - Ledger index (only set on validated ledgers)
-- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
-- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
-- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
-
-This change affects the following methods:
-
-- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
-- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
-- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
-
-## Modifications to `Payment` transaction JSON schema
-
-When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. ([#4733](https://github.com/XRPLF/rippled/pull/4733))
-
-- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: ([#4733](https://github.com/XRPLF/rippled/pull/4733))
-  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
-  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
-  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
-  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
-
-## Modifications to account_info response
-
-- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) ([#3770](https://github.com/XRPLF/rippled/pull/3770))
-- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. ([#4585](https://github.com/XRPLF/rippled/pull/4585))
-  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
-
-## Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
-
-- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. ([#4571](https://github.com/XRPLF/rippled/pull/4571))
-  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. ([#4545](https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579))
-- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
-  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. ([#4288](https://github.com/XRPLF/rippled/issues/4288))
-- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. ([#4620](https://github.com/XRPLF/rippled/pull/4620))

-## Breaking Changes
-
-### Modifications to `amm_info`
-
-The order of error checks has been changed to provide more specific error messages. ([#4924](https://github.com/XRPLF/rippled/pull/4924))
-
-- **Before (API v2)**: When sending an invalid account or asset to `amm_info` while other parameters are not set as expected, the method returns a generic `rpcINVALID_PARAMS` error.
-- **After (API v3)**: The same scenario returns a more specific error: `rpcISSUE_MALFORMED` for malformed assets or `rpcACT_MALFORMED` for malformed accounts.
-
-### Modifications to `ledger_entry`
-
-Added support for string shortcuts to look up fixed-location ledger entries using the `"index"` parameter. ([#5644](https://github.com/XRPLF/rippled/pull/5644))
-
-In API version 3, the following string values can be used with the `"index"` parameter:
-
-- `"index": "amendments"` - Returns the `Amendments` ledger entry
-- `"index": "fee"` - Returns the `FeeSettings` ledger entry
-- `"index": "nunl"` - Returns the `NegativeUNL` ledger entry
-- `"index": "hashes"` - Returns the "short" `LedgerHashes` ledger entry (recent ledger hashes)
-
-These shortcuts are only available in API version 3 and later. In API versions 1 and 2, these string values would result in an error.

-# Distributed Tracing Fundamentals
-
-> **Parent Document**: [OpenTelemetryPlan.md](./OpenTelemetryPlan.md)
-> **Next**: [Architecture Analysis](./01-architecture-analysis.md)
-
----
-
-## What is Distributed Tracing?
-
-Distributed tracing is a method for tracking data objects as they flow through distributed systems. In a network like XRP Ledger, a single transaction touches multiple independent nodes—each with no shared memory or logging. Distributed tracing connects these dots.
-
-**Without tracing:** You see isolated logs on each node with no way to correlate them.
-
-**With tracing:** You see the complete journey of a transaction or an event across all nodes it touched.
-
----
-
-## Core Concepts
-
-### 1. Trace
-
-A **trace** represents the entire journey of a request through the system. It has a unique `trace_id` that stays constant across all nodes.
-
-```
-Trace ID: abc123
-├── Node A: received transaction
-├── Node B: relayed transaction
-├── Node C: included in consensus
-└── Node D: applied to ledger
-```
-
-### 2. Span
-
-A **span** represents a single unit of work within a trace. Each span has:
-
-| Attribute        | Description           | Example                    |
-| ---------------- | --------------------- | -------------------------- |
-| `trace_id`       | Links to parent trace | `abc123`                   |
-| `span_id`        | Unique identifier     | `span456`                  |
-| `parent_span_id` | Parent span (if any)  | `p_span123`                |
-| `name`           | Operation name        | `rpc.submit`               |
-| `start_time`     | When work began       | `2024-01-15T10:30:00Z`     |
-| `end_time`       | When work completed   | `2024-01-15T10:30:00.050Z` |
-| `attributes`     | Key-value metadata    | `tx.hash=ABC...`           |
-| `status`         | OK, ERROR MSG         | `OK`                       |
-
-### 3. Trace Context
-
-**Trace context** is the data that propagates between services to link spans together. It contains:
-
-- `trace_id` - The trace this span belongs to
-- `span_id` - The current span (becomes parent for child spans)
-- `trace_flags` - Sampling decisions
-
----
-
-## How Spans Form a Trace
-
-Spans have parent-child relationships forming a tree structure:
-
-```mermaid

-    subgraph trace["Trace: abc123"]
-        A["tx.submit<br/>span_id: 001<br/>50ms"] --> B["tx.validate<br/>span_id: 002<br/>5ms"]
-        A --> C["tx.relay<br/>span_id: 003<br/>10ms"]
-        A --> D["tx.apply<br/>span_id: 004<br/>30ms"]
-        D --> E["ledger.update<br/>span_id: 005<br/>20ms"]
-    end
-
-    style A fill:#0d47a1,stroke:#082f6a,color:#ffffff
-    style B fill:#1b5e20,stroke:#0d3d14,color:#ffffff

-## Distributed Traces Across Nodes
-
-In distributed systems like rippled, traces span **multiple independent nodes**. The trace context must be propagated in network messages:
-
-```mermaid
-sequenceDiagram
-    participant Client
-    participant NodeA as Node A
-    participant NodeB as Node B
-    participant NodeC as Node C
-
-    Client->>NodeA: Submit TX<br/>(no trace context)
-
-    Note over NodeA: Creates new trace<br/>trace_id: abc123<br/>span: tx.receive
-
-    NodeA->>NodeB: Relay TX<br/>(trace_id: abc123, parent: 001)
-
-    Note over NodeB: Creates child span<br/>span: tx.relay<br/>parent_span_id: 001
-
-    NodeA->>NodeC: Relay TX<br/>(trace_id: abc123, parent: 001)
-
-    Note over NodeC: Creates child span<br/>span: tx.relay<br/>parent_span_id: 001
-
-    Note over NodeA,NodeC: All spans share trace_id: abc123<br/>enabling correlation across nodes
-```
-
----
-
-## Context Propagation
-
-For traces to work across nodes, **trace context must be propagated** in messages.
-
-### What's in the Context (32 bytes)
-
-| Field         | Size       | Description                                             |
-| ------------- | ---------- | ------------------------------------------------------- |
-| `trace_id`    | 16 bytes   | Identifies the entire trace (constant across all nodes) |
-| `span_id`     | 8 bytes    | The sender's current span (becomes parent on receiver)  |
-| `trace_flags` | 4 bytes    | Sampling decision flags                                 |
-| `trace_state` | ~0-4 bytes | Optional vendor-specific data                           |
-
-### How span_id Changes at Each Hop
-
-Only **one** `span_id` travels in the context - the sender's current span. Each node:
-1. Extracts the received `span_id` and uses it as the `parent_span_id`
-2. Creates a **new** `span_id` for its own span
-3. Sends its own `span_id` as the parent when forwarding
-
-```
-Node A                      Node B                      Node C
-──────                      ──────                      ──────
-
-Span AAA                    Span BBB                    Span CCC
-   │                           │                           │
-   ▼                           ▼                           ▼
-Context out:                Context out:                Context out:
-├─ trace_id: abc123         ├─ trace_id: abc123         ├─ trace_id: abc123
-├─ span_id: AAA ──────────► ├─ span_id: BBB ──────────► ├─ span_id: CCC ──────►
-└─ flags: 01                └─ flags: 01                └─ flags: 01
-                               │                           │
-                          parent = AAA               parent = BBB
-```
-
-The `trace_id` stays constant, but `span_id` **changes at every hop** to maintain the parent-child chain.
-
-### Propagation Formats
-
-There are two patterns:
-
-### HTTP/RPC Headers (W3C Trace Context)
-
-```
-traceparent: 00-abc123def456-span789-01
-             │  │             │      │
-             │  │             │      └── Flags (sampled)
-             │  │             └── Parent span ID
-             │  └── Trace ID
-             └── Version
-```
-
-### Protocol Buffers (rippled P2P messages)
-
-```protobuf
-message TMTransaction {
-    bytes rawTransaction = 1;
-    // ... existing fields ...
-
-    // Trace context extension
-    bytes trace_parent = 100;  // W3C traceparent
-    bytes trace_state = 101;   // W3C tracestate
-}
-```
-
----
-
-## Sampling
-
-Not every trace needs to be recorded. **Sampling** reduces overhead:
-
-### Head Sampling (at trace start)
-```
-Request arrives → Random 10% chance → Record or skip entire trace
-```
-- ✅ Low overhead
-- ❌ May miss interesting traces
-
-### Tail Sampling (after trace completes)
-```
-Trace completes → Collector evaluates:
-                  - Error? → KEEP
-                  - Slow? → KEEP
-                  - Normal? → Sample 10%
-```
-- ✅ Never loses important traces
-- ❌ Higher memory usage at collector
-

-| Challenge                          | How Tracing Helps                        |
-| ---------------------------------- | ---------------------------------------- |
-| "Where is my transaction?"         | Follow trace across all nodes it touched |
-| "Why was consensus slow?"          | See timing breakdown of each phase       |
-| "Which node is the bottleneck?"    | Compare span durations across nodes      |
-| "What happened during the outage?" | Correlate errors across the network      |

-## 1.3 Transaction Flow Diagram
-
-Transaction flow spans multiple nodes in the network. Each node creates linked spans to form a distributed trace:
-
-```mermaid
-sequenceDiagram
-    participant Client
-    participant PeerA as Peer A (Receive)
-    participant PeerB as Peer B (Relay)
-    participant PeerC as Peer C (Validate)
-
-    Client->>PeerA: 1. Submit TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerA: tx.receive SPAN START
-        PeerA->>PeerA: HashRouter Deduplication
-        PeerA->>PeerA: tx.validate (child span)
-    end
-
-    PeerA->>PeerB: 2. Relay TX (with trace ctx)
-
-    rect rgb(230, 245, 255)
-        Note over PeerB: tx.receive (linked span)
-    end
-
-    PeerB->>PeerC: 3. Relay TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerC: tx.receive (linked span)
-        PeerC->>PeerC: tx.process
-    end
-
-    Note over Client,PeerC: DISTRIBUTED TRACE (same trace_id: abc123)
-```
-
-### Trace Structure
-
-```
-trace_id: abc123
-├── span: tx.receive (Peer A)
-│   ├── span: tx.validate
-│   └── span: tx.relay
-├── span: tx.receive (Peer B) [parent: Peer A]
-│   └── span: tx.relay
-└── span: tx.receive (Peer C) [parent: Peer B]
-    └── span: tx.process

-## 1.4 Consensus Round Flow
-
-Consensus rounds are multi-phase operations that benefit significantly from tracing:
-
-```mermaid
-flowchart TB
-    subgraph round["consensus.round (root span)"]
-        attrs["Attributes:<br/>xrpl.consensus.ledger.seq = 12345678<br/>xrpl.consensus.mode = proposing<br/>xrpl.consensus.proposers = 35"]

-            est_attrs["proposals_received = 28<br/>disputes_resolved = 3"]
-            est_children["├── consensus.proposal.receive (×28)<br/>├── consensus.proposal.send (×1)<br/>└── consensus.dispute.resolve (×3)"]

-            acc_children["├── ledger.build<br/>└── ledger.validate"]
-        end

-
-## 1.5 RPC Request Flow
-
-RPC requests support W3C Trace Context headers for distributed tracing across services:
-
-```mermaid
-flowchart TB
-    subgraph request["rpc.request (root span)"]
-        http["HTTP Request<br/>POST /<br/>traceparent: 00-abc123...-def456...-01"]

-| Scenario              | What You'll See                                                              | Action                           |
-| --------------------- | ---------------------------------------------------------------------------- | -------------------------------- |
-| **Slow RPC**          | Span showing which phase is slow (parsing, execution, serialization)         | Optimize specific code path      |
-| **Transaction Stuck** | Trace stops at validation; error attribute shows reason                      | Fix transaction parameters       |
-| **Consensus Delay**   | Phase.establish taking too long; proposer attribute shows missing validators | Investigate network connectivity |
-| **Memory Spike**      | Large batch of spans correlating with memory increase                        | Tune batch_size or sampling      |
-| **Network Partition** | Traces missing cross-node links for specific peer                            | Check peer connectivity          |
-
-### 1.8.5 Developer Debugging Workflow
-
-1. **Find Transaction**: Query by `xrpl.tx.hash` to get full trace
-2. **Identify Bottleneck**: Look at span durations to find slowest component
-3. **Check Attributes**: Review `xrpl.tx.validity`, `xrpl.rpc.status` for errors
-4. **Correlate Logs**: Use `trace_id` to find related PerfLog entries
-5. **Compare Nodes**: Filter by `service.instance.id` to compare behavior across nodes

-## 2.1 OpenTelemetry Components
-
-### 2.1.1 SDK Selection
-
-**Primary Choice**: OpenTelemetry C++ SDK (`opentelemetry-cpp`)
-
-| Component                               | Purpose                | Required    |
-| --------------------------------------- | ---------------------- | ----------- |
-| `opentelemetry-cpp::api`                | Tracing API headers    | Yes         |
-| `opentelemetry-cpp::sdk`                | SDK implementation     | Yes         |
-| `opentelemetry-cpp::ext`                | Extensions (exporters) | Yes         |
-| `opentelemetry-cpp::otlp_grpc_exporter` | OTLP/gRPC export       | Recommended |
-| `opentelemetry-cpp::otlp_http_exporter` | OTLP/HTTP export       | Alternative |
-
-### 2.1.2 Instrumentation Strategy
-
-**Manual Instrumentation** (recommended):
-
-| Approach   | Pros                                                              | Cons                                                    |
-| ---------- | ----------------------------------------------------------------- | ------------------------------------------------------- |
-| **Manual** | Precise control, optimized placement, rippled-specific attributes | More development effort                                 |
-| **Auto**   | Less code, automatic coverage                                     | Less control, potential overhead, limited customization |

-## 2.6 Integration with Existing Observability
-
-### 2.6.1 Existing Frameworks Comparison
-
-rippled already has two observability mechanisms. OpenTelemetry complements (not replaces) them:
-
-| Aspect                | PerfLog                       | Beast Insight (StatsD)       | OpenTelemetry             |
-| --------------------- | ----------------------------- | ---------------------------- | ------------------------- |
-| **Type**              | Logging                       | Metrics                      | Distributed Tracing       |
-| **Data**              | JSON log entries              | Counters, gauges, histograms | Spans with context        |
-| **Scope**             | Single node                   | Single node                  | **Cross-node**            |
-| **Output**            | `perf.log` file               | StatsD server                | OTLP Collector            |
-| **Question answered** | "What happened on this node?" | "How many? How fast?"        | "What was the journey?"   |
-| **Correlation**       | By timestamp                  | By metric name               | By `trace_id`             |
-| **Overhead**          | Low (file I/O)                | Low (UDP packets)            | Low-Medium (configurable) |
-
-### 2.6.2 What Each Framework Does Best
-
-#### PerfLog
-- **Purpose**: Detailed local event logging for RPC and job execution
-- **Strengths**:
-  - Rich JSON output with timing data
-  - Already integrated in RPC handlers
-  - File-based, no external dependencies
-- **Limitations**:
-  - Single-node only (no cross-node correlation)
-  - No parent-child relationships between events
-  - Manual log parsing required
-
-```json
-// Example PerfLog entry
-{
-  "time": "2024-01-15T10:30:00.123Z",
-  "method": "submit",
-  "duration_us": 1523,
-  "result": "tesSUCCESS"
-}
-```
-
-#### Beast Insight (StatsD)
-- **Purpose**: Real-time metrics for monitoring dashboards
-- **Strengths**:
-  - Aggregated metrics (counters, gauges, histograms)
-  - Low overhead (UDP, fire-and-forget)
-  - Good for alerting thresholds
-- **Limitations**:
-  - No request-level detail
-  - No causal relationships
-  - Single-node perspective
-
-```cpp
-// Example StatsD usage in rippled
-insight.increment("rpc.submit.count");
-insight.gauge("ledger.age", age);
-insight.timing("consensus.round", duration);
-```
-
-#### OpenTelemetry (NEW)
-- **Purpose**: Distributed request tracing across nodes
-- **Strengths**:
-  - **Cross-node correlation** via `trace_id`
-  - Parent-child span relationships
-  - Rich attributes per span
-  - Industry standard (CNCF)
-- **Limitations**:
-  - Requires collector infrastructure
-  - Higher complexity than logging
-
-```cpp
-// Example OpenTelemetry span
-auto span = telemetry.startSpan("tx.relay");
-span->SetAttribute("tx.hash", hash);
-span->SetAttribute("peer.id", peerId);
-// Span automatically linked to parent via context
-```
-
-### 2.6.3 When to Use Each
-
-| Scenario                                | PerfLog   | StatsD | OpenTelemetry |
-| --------------------------------------- | --------- | ------ | ------------- |
-| "How many TXs per second?"              | ❌         | ✅      | ❌             |
-| "What's the p99 RPC latency?"           | ❌         | ✅      | ✅             |
-| "Why was this specific TX slow?"        | ⚠️ partial | ❌      | ✅             |
-| "Which node delayed consensus?"         | ❌         | ❌      | ✅             |
-| "What happened on node X at time T?"    | ✅         | ❌      | ✅             |
-| "Show me the TX journey across 5 nodes" | ❌         | ❌      | ✅             |

-### 2.6.5 Correlation with PerfLog
-
-Trace IDs can be correlated with existing PerfLog entries for comprehensive debugging:
-
-```cpp
-// In RPCHandler.cpp - correlate trace with PerfLog
-Status doCommand(RPC::JsonContext& context, Json::Value& result)
-{
-    // Start OpenTelemetry span
-    auto span = context.app.getTelemetry().startSpan(
-        "rpc.command." + context.method);
-
-    // Get trace ID for correlation
-    auto traceId = span->GetContext().trace_id().IsValid()
-        ? toHex(span->GetContext().trace_id())
-        : "";
-
-    // Use existing PerfLog with trace correlation
-    auto const curId = context.app.getPerfLog().currentId();
-    context.app.getPerfLog().rpcStart(context.method, curId);
-
-    // Future: Add trace ID to PerfLog entry
-    // context.app.getPerfLog().setTraceId(curId, traceId);
-
-    try {
-        auto ret = handler(context, result);
-        context.app.getPerfLog().rpcFinish(context.method, curId);
-        span->SetStatus(opentelemetry::trace::StatusCode::kOk);

-### Key Principles
-
-1. **Minimal Intrusion**: Instrumentation should not alter existing control flow
-2. **Zero-Cost When Disabled**: Use compile-time flags and no-op implementations
-3. **Backward Compatibility**: Protocol Buffer extensions use high field numbers
-4. **Graceful Degradation**: Tracing failures must not affect node operation

-| Memory        | 2-5 MB     | Batch buffer for pending spans      |
-| Network       | 10-50 KB/s | Compressed OTLP export to collector |
-| Latency (p99) | <2%        | With proper sampling configuration  |

-## 3.4 Detailed CPU Overhead Analysis
-
-### 3.4.1 Per-Operation Costs
-
-| Operation             | Time (ns) | Frequency              | Impact     |
-| --------------------- | --------- | ---------------------- | ---------- |
-| Span creation         | 200-500   | Every traced operation | Low        |
-| Span end              | 100-200   | Every traced operation | Low        |
-| SetAttribute (string) | 80-120    | 3-5 per span           | Low        |
-| SetAttribute (int)    | 40-60     | 2-3 per span           | Negligible |
-| AddEvent              | 50-80     | 0-2 per span           | Negligible |
-| Context injection     | 150-250   | Per outgoing message   | Low        |
-| Context extraction    | 100-180   | Per incoming message   | Low        |
-| GetCurrent context    | 10-20     | Thread-local access    | Negligible |

-
-**Transaction Tracing Overhead (~2.4μs total)**
-
-</div>
-
-**Overhead percentage**: 2.4 μs / 200 μs (avg tx processing) = **~1.2%**
-
-### 3.4.3 Consensus Round Overhead
-
-| Operation              | Count | Cost (ns) | Total      |
-| ---------------------- | ----- | --------- | ---------- |
-| consensus.round span   | 1     | ~1000     | ~1 μs      |
-| consensus.phase spans  | 3     | ~700      | ~2.1 μs    |
-| proposal.receive spans | ~20   | ~600      | ~12 μs     |
-| proposal.send spans    | ~3    | ~600      | ~1.8 μs    |

-| **TOTAL**              |       |           | **~23 μs** |
-
-**Overhead percentage**: 23 μs / 3s (typical round) = **~0.0008%** (negligible)
-
-### 3.4.4 RPC Request Overhead
-
-| Operation        | Cost (ns)    |
-| ---------------- | ------------ |

-| rpc.command span | ~600         |
-| Context extract  | ~250         |
-| Context inject   | ~200         |
-| **TOTAL**        | **~1.75 μs** |
-
-- Fast RPC (1ms): 1.75 μs / 1ms = **~0.175%**
-- Slow RPC (100ms): 1.75 μs / 100ms = **~0.002%**

-| **Medium** | Minor modifications to existing functions; clear boundaries      | Comprehensive unit tests           |
-| **High**   | Changes to core logic or data structures; potential side effects | Integration tests + staged rollout |
-
-### 3.9.4 Architectural Impact Assessment
-
-| Aspect               | Impact  | Justification                                                         |
-| -------------------- | ------- | --------------------------------------------------------------------- |
-| **Data Flow**        | None    | Tracing is purely observational; no business logic changes            |
-| **Threading Model**  | Minimal | Context propagation uses thread-local storage (standard OTel pattern) |
-| **Memory Model**     | Low     | Bounded queues prevent unbounded growth; RAII ensures cleanup         |
-| **Network Protocol** | Low     | Optional fields in protobuf (high field numbers); backward compatible |
-| **Configuration**    | None    | New config section; existing configs unaffected                       |
-| **Build System**     | Low     | Optional CMake flag; builds work without OpenTelemetry                |
-| **Dependencies**     | Low     | OpenTelemetry SDK is optional; null implementation when disabled      |
-
-### 3.9.5 Backward Compatibility
-
-| Compatibility   | Status | Notes                                                 |
-| --------------- | ------ | ----------------------------------------------------- |
-| **Config File** | ✅ Full | New `[telemetry]` section is optional                 |
-| **Protocol**    | ✅ Full | Optional protobuf fields with high field numbers      |
-| **Build**       | ✅ Full | `XRPL_ENABLE_TELEMETRY=OFF` produces identical binary |
-| **Runtime**     | ✅ Full | `enabled=0` produces zero overhead                    |
-| **API**         | ✅ Full | No changes to public RPC or P2P APIs                  |
-
-### 3.9.6 Rollback Strategy
-
-If issues are discovered after deployment:
-
-1. **Immediate**: Set `enabled=0` in config and restart (zero code change)
-2. **Quick**: Rebuild with `XRPL_ENABLE_TELEMETRY=OFF`
-3. **Complete**: Revert telemetry commits (clean separation makes this easy)
-
-### 3.9.7 Code Change Examples
-
-**Minimal RPC Instrumentation (Low Intrusiveness):**
-```cpp
-// Before
-void ServerHandler::onRequest(...) {
-    auto result = processRequest(req);
-    send(result);
-}
-
-// After (only ~10 lines added)
-void ServerHandler::onRequest(...) {
-    XRPL_TRACE_RPC(app_.getTelemetry(), "rpc.request");  // +1 line
-    XRPL_TRACE_SET_ATTR("xrpl.rpc.command", command);     // +1 line
-
-    auto result = processRequest(req);
-
-    XRPL_TRACE_SET_ATTR("xrpl.rpc.status", status);       // +1 line
-    send(result);
-}
-```
-
-**Consensus Instrumentation (Medium Intrusiveness):**
-```cpp
-// Before
-void RCLConsensusAdaptor::startRound(...) {
-    // ... existing logic
-}
-
-// After (context storage required)

-### 5.8.5 TraceQL Query Examples
-
-Common queries for rippled traces:
-
-```
-# Find all traces for a specific transaction hash
-{resource.service.name="rippled" && span.xrpl.tx.hash="ABC123..."}
-
-# Find slow RPC commands (>100ms)
-{resource.service.name="rippled" && name=~"rpc.command.*"} | duration > 100ms
-
-# Find consensus rounds taking >5 seconds
-{resource.service.name="rippled" && name="consensus.round"} | duration > 5s
-
-# Find failed transactions with error details
-{resource.service.name="rippled" && name="tx.validate" && status.code=error}
-
-# Find transactions relayed to many peers
-{resource.service.name="rippled" && name="tx.relay"} | span.xrpl.tx.relay_count > 10
-
-# Compare latency across nodes
-{resource.service.name="rippled" && name="rpc.command.account_info"} | avg(duration) by (resource.service.instance.id)
-```
-
-### 5.8.6 Correlation with PerfLog
-
-To correlate OpenTelemetry traces with existing PerfLog data:
-
-**Step 1: Configure Loki to ingest PerfLog**
-
-```yaml
-# promtail-config.yaml
-scrape_configs:
-  - job_name: rippled-perflog
-    static_configs:
-      - targets:
-          - localhost
-        labels:
-          job: rippled
-          __path__: /var/log/rippled/perf*.log
-    pipeline_stages:
-      - json:
-          expressions:
-            trace_id: trace_id
-            ledger_seq: ledger_seq
-            tx_hash: tx_hash
-      - labels:
-          trace_id:
-          ledger_seq:
-          tx_hash:
-```
-
-**Step 2: Add trace_id to PerfLog entries**
-
-Modify PerfLog to include trace_id when available:
-
-```cpp
-// In PerfLog output, add trace_id from current span context
-void logPerf(Json::Value& entry) {
-    auto span = opentelemetry::trace::GetSpan(
-        opentelemetry::context::RuntimeContext::GetCurrent());
-    if (span && span->GetContext().IsValid()) {
-        char traceIdHex[33];
-        span->GetContext().trace_id().ToLowerBase16(traceIdHex);
-        entry["trace_id"] = std::string(traceIdHex, 32);
-    }
-    // ... existing logging
-}
-```
-
-**Step 3: Configure Grafana trace-to-logs link**
-
-In Tempo data source configuration, set up the derived field:
-
-```yaml
-jsonData:
-  tracesToLogs:
-    datasourceUid: loki
-    tags: ['trace_id', 'xrpl.tx.hash']
-    filterByTraceID: true
-    filterBySpanID: false

-### 5.8.7 Correlation with Insight/StatsD Metrics
-
-To correlate traces with existing Beast Insight metrics:
-
-**Step 1: Export Insight metrics to Prometheus**
-
-```yaml
-# prometheus.yaml
-scrape_configs:
-  - job_name: 'rippled-statsd'
-    static_configs:
-      - targets: ['statsd-exporter:9102']
-```
-
-**Step 2: Add exemplars to metrics**
-
-OpenTelemetry SDK automatically adds exemplars (trace IDs) to metrics when using the Prometheus exporter. This links metrics spikes to specific traces.
-
-**Step 3: Configure Grafana metric-to-trace link**
-
-```yaml
-# In Prometheus data source
-jsonData:
-  exemplarTraceIdDestinations:
-    - name: trace_id
-      datasourceUid: tempo
-```
-
-**Step 4: Dashboard panel with exemplars**
-
-```json
-{
-  "title": "RPC Latency with Trace Links",
-  "type": "timeseries",
-  "datasource": "Prometheus",
-  "targets": [
-    {
-      "expr": "histogram_quantile(0.99, rate(rippled_rpc_duration_seconds_bucket[5m]))",
-      "exemplar": true
-    }
-  ]
-}
-```
-
-This allows clicking on metric data points to jump directly to the related trace.

-
-| Quick Win                      | Effort   | Value  | When to Deploy |
-| ------------------------------ | -------- | ------ | -------------- |
-| **RPC Command Tracing**        | 2 days   | High   | Week 2         |
-| **RPC Latency Histograms**     | 0.5 days | High   | Week 2         |
-| **Error Rate Dashboard**       | 0.5 days | Medium | Week 2         |
-| **Transaction Submit Tracing** | 1 day    | High   | Week 3         |
-| **Consensus Round Duration**   | 1 day    | Medium | Week 6         |
-
-### 6.10.3 CRAWL Phase (Weeks 1-2)
-
-**Goal**: Get basic tracing working with minimal code changes.
-
-**What You Get**:
-- RPC request/response traces for all commands
-- Latency breakdown per RPC command
-- Error visibility with stack traces
-- Basic Grafana dashboard
-
-**Code Changes**: ~15 lines in `ServerHandler.cpp`, ~40 lines in new telemetry module
-
-**Why Start Here**:
-- RPC is the lowest-risk, highest-visibility component
-- Immediate value for debugging client issues
-- No cross-node complexity
-- Single file modification to existing code
-
-### 6.10.4 WALK Phase (Weeks 3-5)
-
-**Goal**: Add transaction lifecycle tracing across nodes.
-
-**What You Get**:
-- End-to-end transaction traces from submit to relay
-- Cross-node correlation (see transaction path)
-- HashRouter deduplication visibility
-- Relay latency metrics
-
-**Code Changes**: ~120 lines across 4 files, plus protobuf extension
-
-**Why Do This Second**:
-- Builds on RPC tracing (transactions submitted via RPC)
-- Moderate complexity (requires context propagation)
-- High value for debugging transaction issues
-
-### 6.10.5 RUN Phase (Weeks 6-9)
-
-**Goal**: Full observability including consensus.
-
-**What You Get**:
-- Complete consensus round visibility
-- Phase transition timing
-- Validator proposal tracking
-- Full end-to-end traces (client → RPC → TX → consensus → ledger)
-
-**Code Changes**: ~100 lines across 3 consensus files
-
-**Why Do This Last**:
-- Highest complexity (consensus is critical path)
-- Requires thorough testing
-- Lower relative value (consensus issues are rarer)

-## 7.4 Architecture Considerations
-
-### 7.4.1 Collector Placement
-
-| Strategy      | Description          | Pros                     | Cons                    |
-| ------------- | -------------------- | ------------------------ | ----------------------- |
-| **Sidecar**   | Collector per node   | Isolation, simple config | Resource overhead       |
-| **DaemonSet** | Collector per host   | Shared resources         | Complexity              |
-| **Gateway**   | Central collector(s) | Centralized processing   | Single point of failure |
-
-**Recommendation**: Use **Gateway** pattern with regional collectors for rippled networks:
-- One collector cluster per datacenter/region
-- Tail-based sampling at collector level
-- Multiple export destinations for redundancy
-
-### 7.4.2 Sampling Strategy
-
-```mermaid
-flowchart LR
-    subgraph head["Head Sampling (Node)"]
-        hs[10% probabilistic]
-    end
-
-    subgraph tail["Tail Sampling (Collector)"]

-    style final fill:#bf360c,stroke:#8c2809,color:#fff
-```
-
-### 7.4.3 Data Retention
-
-| Environment | Hot Storage | Warm Storage | Cold Archive |
-| ----------- | ----------- | ------------ | ------------ |
-| Development | 24 hours    | N/A          | N/A          |
-| Staging     | 7 days      | N/A          | N/A          |
-| Production  | 7 days      | 30 days      | many years   |
-
----
-
-## 7.5 Integration Checklist
-
-- [ ] Choose primary backend (Tempo recommended for cost/features)
-- [ ] Deploy collector cluster with high availability
-- [ ] Configure tail-based sampling for error/latency traces
-- [ ] Set up Grafana dashboards for trace visualization
-- [ ] Configure alerts for trace anomalies
-- [ ] Establish data retention policies
-- [ ] Test trace correlation with logs and metrics

-
-**Step 1: Find the trace**
-```
-# In Grafana Explore with Tempo
-{resource.service.name="rippled" && span.xrpl.tx.hash="ABC123..."}
-```
-
-**Step 2: Get the trace_id from the trace view**
-```
-Trace ID: 4bf92f3577b34da6a3ce929d0e0e4736
-```
-
-**Step 3: Find related PerfLog entries**
-```
-# In Grafana Explore with Loki
-{job="rippled"} |= "4bf92f3577b34da6a3ce929d0e0e4736"
-```
-
-**Step 4: Check Insight metrics for the time window**
-```
-# In Grafana with Prometheus
-rate(rippled_tx_applied_total[1m])
-  @ timestamp_from_trace
-```

-
-## Executive Summary
-
-This document provides a comprehensive implementation plan for integrating OpenTelemetry distributed tracing into the rippled XRP Ledger node software. The plan addresses the unique challenges of a decentralized peer-to-peer system where trace context must propagate across network boundaries between independent nodes.
-
-### Key Benefits
-
-- **End-to-end transaction visibility**: Track transactions from submission through consensus to ledger inclusion
-- **Consensus round analysis**: Understand timing and behavior of consensus phases across validators
-- **RPC performance insights**: Identify slow handlers and optimize response times
-- **Network topology understanding**: Visualize message propagation patterns between peers
-- **Incident debugging**: Correlate events across distributed nodes during issues
-
-### Estimated Performance Overhead
-
-| Metric        | Overhead   | Notes                               |
-| ------------- | ---------- | ----------------------------------- |
-| CPU           | 1-3%       | Span creation and attribute setting |

-## 1. Architecture Analysis
-
-The rippled node consists of several key components that require instrumentation for comprehensive distributed tracing. The main areas include the RPC server (HTTP/WebSocket), Overlay P2P network, Consensus mechanism (RCLConsensus), JobQueue for async task execution, and existing observability infrastructure (PerfLog, Insight/StatsD, Journal logging).
-
-Key trace points span across transaction submission via RPC, peer-to-peer message propagation, consensus round execution, and ledger building. The implementation prioritizes high-value, low-risk components first: RPC handlers provide immediate value with minimal risk, while consensus tracing requires careful implementation to avoid timing impacts.
-
-➡️ **[Read full Architecture Analysis](./01-architecture-analysis.md)**
-
----
-
-## 2. Design Decisions
-
-The OpenTelemetry C++ SDK is selected for its CNCF backing, active development, and native performance characteristics. Traces are exported via OTLP/gRPC (primary) or OTLP/HTTP (fallback) to an OpenTelemetry Collector, which provides flexible routing and sampling.
-
-Span naming follows a hierarchical `<component>.<operation>` convention (e.g., `rpc.submit`, `tx.relay`, `consensus.round`). Context propagation uses W3C Trace Context headers for HTTP and embedded Protocol Buffer fields for P2P messages. The implementation coexists with existing PerfLog and Insight observability systems through correlation IDs.
-
-➡️ **[Read full Design Decisions](./02-design-decisions.md)**
-
----
-
-## 3. Implementation Strategy
-
-The telemetry code is organized under `include/xrpl/telemetry/` for headers and `src/libxrpl/telemetry/` for implementation. Key principles include RAII-based span management via `SpanGuard`, conditional compilation with `XRPL_ENABLE_TELEMETRY`, and minimal runtime overhead through batch processing and efficient sampling.
-
-Performance optimization strategies include probabilistic head sampling (10% default), tail-based sampling at the collector for errors and slow traces, batch export to reduce network overhead, and conditional instrumentation that compiles to no-ops when disabled.
-
-➡️ **[Read full Implementation Strategy](./03-implementation-strategy.md)**

-## 5. Configuration Reference
-
-Configuration is handled through the `[telemetry]` section in `xrpld.cfg` with options for enabling/disabling, exporter selection, endpoint configuration, sampling ratios, and component-level filtering. CMake integration includes a `XRPL_ENABLE_TELEMETRY` option for compile-time control.
-
-OpenTelemetry Collector configurations are provided for development (with Jaeger) and production (with tail-based sampling, Tempo, and Elastic APM). Docker Compose examples enable quick local development environment setup.

-## 7. Observability Backends
-
-For development and testing, Jaeger provides easy setup with a good UI. For production deployments, Grafana Tempo is recommended for its cost-effectiveness and Grafana integration, while Elastic APM is ideal for organizations with existing Elastic infrastructure.
-
-The recommended production architecture uses a gateway collector pattern with regional collectors performing tail-based sampling, routing traces to multiple backends (Tempo for primary storage, Elastic for log correlation, S3/GCS for long-term archive).

-   Configure sanitizers based on environment variables.
-
-   This module reads the following environment variables:
-   - SANITIZERS: The sanitizers to enable. Possible values:
-     - "address"
-     - "address,undefinedbehavior"
-     - "thread"
-     - "thread,undefinedbehavior"
-     - "undefinedbehavior"
-
-   The compiler type and platform are detected in CompilationEnv.cmake.
-   The sanitizer compile options are applied to the 'common' interface library
-   which is linked to all targets in the project.
-
-   Internal flag variables set by this module:
-
-   - SANITIZER_TYPES: List of sanitizer types to enable (e.g., "address",
-     "thread", "undefined"). And two more flags for undefined behavior sanitizer (e.g., "float-divide-by-zero", "unsigned-integer-overflow").
-     This list is joined with commas and passed to -fsanitize=<list>.
-
-   - SANITIZERS_COMPILE_FLAGS: Compiler flags for sanitizer instrumentation.
-     Includes:
-     * -fno-omit-frame-pointer: Preserves frame pointers for stack traces
-     * -O1: Minimum optimization for reasonable performance
-     * -fsanitize=<types>: Enables sanitizer instrumentation
-     * -fsanitize-ignorelist=<path>: (Clang only) Compile-time ignorelist
-     * -mcmodel=large/medium: (GCC only) Code model for large binaries
-     * -Wno-stringop-overflow: (GCC only) Suppresses false positive warnings
-     * -Wno-tsan: (For GCC TSAN combination only) Suppresses atomic_thread_fence warnings
-
-   - SANITIZERS_LINK_FLAGS: Linker flags for sanitizer runtime libraries.
-     Includes:
-     * -fsanitize=<types>: Links sanitizer runtime libraries
-     * -mcmodel=large/medium: (GCC only) Matches compile-time code model
-
-   - SANITIZERS_RELOCATION_FLAGS: (GCC only) Code model flags for linking.
-     Used to handle large instrumented binaries on x86_64:
-     * -mcmodel=large: For AddressSanitizer (prevents relocation errors)
-     * -mcmodel=medium: For ThreadSanitizer (large model is incompatible)

-# Conan lockfile
-
-To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
-
-The `conan.lock` file in the repository contains a "snapshot" of the current
-dependencies. It is implicitly used when running `conan` commands, so you don't
-need to specify it.
-
-You have to update this file every time you add a new dependency or change a
-revision or version of an existing dependency.
-
-To update a lockfile, run from the repository root: `./conan/lockfile/regenerate.sh`

-## Building with Sanitizers
-
-### Summary
-
-Follow the same instructions as mentioned in [BUILD.md](../../BUILD.md) but with the following changes:
-
-1. Make sure you have a clean build directory.
-2. Set the `SANITIZERS` environment variable before calling conan install and cmake. Only set it once. Make sure both conan and cmake read the same values.
-   Example: `export SANITIZERS=address,undefinedbehavior`
-3. Optionally use `--profile:all sanitizers` with Conan to build dependencies with sanitizer instrumentation. [!NOTE]Building with sanitizer-instrumented dependencies is slower but produces fewer false positives.
-4. Set `ASAN_OPTIONS`, `LSAN_OPTIONS`, `UBSAN_OPTIONS` and `TSAN_OPTIONS` environment variables to configure sanitizer behavior when running executables. [More details below](#running-tests-with-sanitizers).
-
----
-
-### Build steps:
-
-```bash
-cd /path/to/rippled
-rm -rf .build
-mkdir .build
-cd .build
-```
-
-#### Install dependencies
-
-The `SANITIZERS` environment variable is used by both Conan and CMake.
-
-```bash
-export SANITIZERS=address,undefinedbehavior
-# Standard build (without instrumenting dependencies)
-conan install .. --output-folder . --build missing --settings build_type=Debug
-
-# Or with sanitizer-instrumented dependencies (takes longer but fewer false positives)
-conan install .. --output-folder . --profile:all sanitizers --build missing --settings build_type=Debug
-```
-
-[!CAUTION]
-Do not mix Address and Thread sanitizers - they are incompatible.
-
-Since you already set the `SANITIZERS` environment variable when running Conan, same values will be read for the next part.
-
-#### Call CMake
-
-```bash
-cmake .. -G Ninja \
-    -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake \
-    -DCMAKE_BUILD_TYPE=Debug \
-    -Dtests=ON -Dxrpld=ON
-```
-
-#### Build
-
-```bash
-cmake --build . --parallel 4
-```
-
-## Running Tests with Sanitizers
-
-### AddressSanitizer (ASAN)
-
-**IMPORTANT**: ASAN with Boost produces many false positives. Use these options:
-
-```bash
-export ASAN_OPTIONS="print_stacktrace=1:detect_container_overflow=0:suppressions=path/to/asan.supp:halt_on_error=0:log_path=asan.log"
-export LSAN_OPTIONS="suppressions=path/to/lsan.supp:halt_on_error=0:log_path=lsan.log"
-
-# Run tests
-./xrpld --unittest --unittest-jobs=5
-```
-
-**Why `detect_container_overflow=0`?**
-
-- Boost intrusive containers (used in `aged_unordered_container`) trigger false positives
-- Boost context switching (used in `Workers.cpp`) confuses ASAN's stack tracking
-- Since we usually don't build Boost (because we don't want to instrument Boost and detect issues in Boost code) with ASAN but use Boost containers in ASAN instrumented rippled code, it generates false positives.
-- Building dependencies with ASAN instrumentation reduces false positives. But we don't want to instrument dependencies like Boost with ASAN because it is slow (to compile as well as run tests) and not necessary.
-- See: https://github.com/google/sanitizers/wiki/AddressSanitizerContainerOverflow
-- More such flags are detailed [here](https://github.com/google/sanitizers/wiki/AddressSanitizerFlags)
-
-### ThreadSanitizer (TSan)
-
-```bash
-export TSAN_OPTIONS="suppressions=path/to/tsan.supp halt_on_error=0 log_path=tsan.log"
-
-# Run tests
-./xrpld --unittest --unittest-jobs=5
-```
-
-More details [here](https://github.com/google/sanitizers/wiki/ThreadSanitizerCppManual).
-
-### LeakSanitizer (LSan)
-
-LSan is automatically enabled with ASAN. To disable it:
-
-```bash
-export ASAN_OPTIONS="detect_leaks=0"
-```
-
-More details [here](https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer).
-
-### UndefinedBehaviorSanitizer (UBSan)
-
-```bash
-export UBSAN_OPTIONS="suppressions=path/to/ubsan.supp:print_stacktrace=1:halt_on_error=0:log_path=ubsan.log"
-
-# Run tests
-./xrpld --unittest --unittest-jobs=5
-```
-

-
-## Suppression Files
-
-[!NOTE] Attached files contain more details.
-
-### [`asan.supp`](../../sanitizers/suppressions/asan.supp)
-
-- **Purpose**: Suppress AddressSanitizer (ASAN) errors only
-- **Format**: `interceptor_name:<pattern>` where pattern matches file names. Supported suppression types are:
-  - interceptor_name
-  - interceptor_via_fun
-  - interceptor_via_lib
-  - odr_violation
-- **More info**: [AddressSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer)
-- **Note**: Cannot suppress stack-buffer-overflow, container-overflow, etc.
-
-### [`lsan.supp`](../../sanitizers/suppressions/lsan.supp)
-
-- **Purpose**: Suppress LeakSanitizer (LSan) errors only
-- **Format**: `leak:<pattern>` where pattern matches function/file names
-- **More info**: [LeakSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer)
-
-### [`ubsan.supp`](../../sanitizers/suppressions/ubsan.supp)
-
-- **Purpose**: Suppress undefinedbehaviorSanitizer errors
-- **Format**: `<error_type>:<pattern>` (e.g., `unsigned-integer-overflow:protobuf`)
-- **Covers**: Intentional overflows in sanitizers/suppressions libraries (protobuf, gRPC, stdlib)
-- More info [UBSan suppressions](https://clang.llvm.org/docs/SanitizerSpecialCaseList.html).
-
-### [`tsan.supp`](../../sanitizers/suppressions/tsan.supp)
-
-- **Purpose**: Suppress ThreadSanitizer data race warnings
-- **Format**: `race:<pattern>` where pattern matches function/file names
-- **More info**: [ThreadSanitizer suppressions](https://github.com/google/sanitizers/wiki/ThreadSanitizerSuppressions)
-
-### [`sanitizer-ignorelist.txt`](../../sanitizers/suppressions/sanitizer-ignorelist.txt)
-
-- **Purpose**: Compile-time ignorelist for all sanitizers
-- **Usage**: Passed via `-fsanitize-ignorelist=absolute/path/to/sanitizer-ignorelist.txt`
-- **Format**: `<level>:<pattern>` (e.g., `src:Workers.cpp`)
-
-## Troubleshooting
-
-### "ASAN is ignoring requested \_\_asan_handle_no_return" warnings
-
-These warnings appear when using Boost context switching and are harmless. They indicate potential false positives.
-
-### Sanitizer Mismatch Errors
-
-If you see undefined symbols like `___tsan_atomic_load` when building with ASAN:
-
-**Problem**: Dependencies were built with a different sanitizer than the main project.
-
-**Solution**: Rebuild everything with the same sanitizer:
-
-```bash
-rm -rf .build
-# Then follow the build instructions above
-```
-
-Then review the log files: `asan.log.*`, `ubsan.log.*`, `tsan.log.*`

+SSE2 code and benches have not been updated yet. I will do those next.
+
+Compilers versions are gcc 4.6.3, icc 13.1.1, clang 3.4-1~exp1.
+
+Batch verification time (in parentheses) is the average time per 1 verification in a batch of 64 signatures. Counts are in thousands of cycles.
+
+Note that SSE2 performance may be less impressive on AMD & older CPUs with slower SSE ops!
+
+Visual Studio performance for `ge25519_scalarmult_base_niels` will lag behind a bit until optimized assembler versions of `ge25519_scalarmult_base_choose_niels`
+are made.

+#### Compilation
+
+No configuration is needed **if you are compiling against OpenSSL**. 
+
+##### Hash Options
+
+If you are not compiling aginst OpenSSL, you will need a hash function.
+
+To use a simple/**slow** implementation of SHA-512, use `-DED25519_REFHASH` when compiling `ed25519.c`. 
+This should never be used except to verify the code works when OpenSSL is not available.
+
+To use a custom hash function, use `-DED25519_CUSTOMHASH` when compiling `ed25519.c` and put your 
+custom hash implementation in ed25519-hash-custom.h. The hash must have a 512bit digest and implement
+
+	struct ed25519_hash_context;
+
+	void ed25519_hash_init(ed25519_hash_context *ctx);
+	void ed25519_hash_update(ed25519_hash_context *ctx, const uint8_t *in, size_t inlen);
+	void ed25519_hash_final(ed25519_hash_context *ctx, uint8_t *hash);
+	void ed25519_hash(uint8_t *hash, const uint8_t *in, size_t inlen);
+
+##### Random Options
+
+If you are not compiling aginst OpenSSL, you will need a random function for batch verification.
+
+To use a custom random function, use `-DED25519_CUSTOMRANDOM` when compiling `ed25519.c` and put your 
+custom hash implementation in ed25519-randombytes-custom.h. The random function must implement:
+
+	void ED25519_FN(ed25519_randombytes_unsafe) (void *p, size_t len);
+
+Use `-DED25519_TEST` when compiling `ed25519.c` to use a deterministically seeded, non-thread safe CSPRNG 
+variant of Bob Jenkins [ISAAC](http://en.wikipedia.org/wiki/ISAAC_%28cipher%29)
+
+##### Minor options
+
+Use `-DED25519_INLINE_ASM` to disable the use of custom assembler routines and instead rely on portable C.
+
+Use `-DED25519_FORCE_32BIT` to force the use of 32 bit routines even when compiling for 64 bit.
+
+##### 32-bit
+
+	gcc ed25519.c -m32 -O3 -c
+
+##### 64-bit
+
+	gcc ed25519.c -m64 -O3 -c
+
+##### SSE2
+
+	gcc ed25519.c -m32 -O3 -c -DED25519_SSE2 -msse2
+	gcc ed25519.c -m64 -O3 -c -DED25519_SSE2
+
+clang and icc are also supported
+
+
+#### Usage
+
+To use the code, link against `ed25519.o -mbits` and:
+
+	#include "ed25519.h"
+
+Add `-lssl -lcrypto` when using OpenSSL (Some systems don't need -lcrypto? It might be trial and error).
+
+To generate a private key, simply generate 32 bytes from a secure
+cryptographic source:
+
+	ed25519_secret_key sk;
+	randombytes(sk, sizeof(ed25519_secret_key));
+
+To generate a public key:
+
+	ed25519_public_key pk;
+	ed25519_publickey(sk, pk);
+
+To sign a message:
+
+	ed25519_signature sig;
+	ed25519_sign(message, message_len, sk, pk, signature);
+
+To verify a signature:
+
+	int valid = ed25519_sign_open(message, message_len, pk, signature) == 0;
+
+To batch verify signatures:
+
+	const unsigned char *mp[num] = {message1, message2..}
+	size_t ml[num] = {message_len1, message_len2..}
+	const unsigned char *pkp[num] = {pk1, pk2..}
+	const unsigned char *sigp[num] = {signature1, signature2..}
+	int valid[num]
+
+	/* valid[i] will be set to 1 if the individual signature was valid, 0 otherwise */
+	int all_valid = ed25519_sign_open_batch(mp, ml, pkp, sigp, num, valid) == 0;
+
+**Note**: Batch verification uses `ed25519_randombytes_unsafe`, implemented in 
+`ed25519-randombytes.h`, to generate random scalars for the verification code. 
+The default implementation now uses OpenSSLs `RAND_bytes`.
+
+Unlike the [SUPERCOP](http://bench.cr.yp.to/supercop.html) version, signatures are
+not appended to messages, and there is no need for padding in front of messages. 
+Additionally, the secret key does not contain a copy of the public key, so it is 
+32 bytes instead of 64 bytes, and the public key must be provided to the signing
+function.
+
+##### Curve25519
+
+Curve25519 public keys can be generated thanks to 
+[Adam Langley](http://www.imperialviolet.org/2013/05/10/fastercurve25519.html) 
+leveraging Ed25519's precomputed basepoint scalar multiplication.
+
+	curved25519_key sk, pk;
+	randombytes(sk, sizeof(curved25519_key));
+	curved25519_scalarmult_basepoint(pk, sk);
+
+Note the name is curved25519, a combination of curve and ed25519, to prevent 
+name clashes. Performance is slightly faster than short message ed25519
+signing due to both using the same code for the scalar multiply.
+
+#### Testing
+
+Fuzzing against reference implemenations is now available. See [fuzz/README](fuzz/README.md).
+
+Building `ed25519.c` with `-DED25519_TEST` and linking with `test.c` will run basic sanity tests
+and benchmark each function. `test-batch.c` has been incorporated in to `test.c`.
+
+`test-internals.c` is standalone and built the same way as `ed25519.c`. It tests the math primitives
+with extreme values to ensure they function correctly. SSE2 is now supported.
