Competition on Robinhood Chain does not begin only when a transaction is submitted. It begins when a system first receives the latest onchain state. For searchers, trading bots, and automated trading systems, receiving a block earlier means updating local state, identifying opportunities, and constructing transactions sooner.

BlockRazor deployed benchmark clients in three AWS US East (Ohio) Availability Zones and connected each client to both BlockRazor Robinhood Chain Sequencer Feed Ultra and the official Robinhood Chain Sequencer Feed. For matching blocks, the test compared which feed reached the same client first. In the October 2, 2026 benchmark, BlockRazor maintained **0.000 ms relative latency from P50 through P99 in all three zones**. The official feed recorded P50 relative latency of **7.449–30.732 ms** and P99 relative latency of **17.949–104.372 ms**.

The results show that BlockRazor consistently delivered matching blocks earlier while providing a more stable delivery window under tail-latency conditions.

## What Is Robinhood Chain Sequencer Feed?

Robinhood Chain Sequencer Feed is a real-time block data stream pushed by the sequencer. Nitro nodes subscribe to the feed through WebSocket, receive new blocks, and continuously update their local view of the chain.

Unlike an RPC client that actively queries historical or latest data, Sequencer Feed pushes new blocks directly to subscribed nodes. It is an important data input for tracking the latest Robinhood Chain state. Feed speed and stability affect how quickly a node catches up with blocks and updates its state. Network jitter, connection interruptions, or high tail latency can temporarily leave a node behind the latest height, causing systems that depend on the node to make decisions from older state.

The difference may be negligible for ordinary data queries, but it is important to searchers, trading bots, and automated trading systems: receive the block earlier → update node state earlier → identify onchain opportunities earlier → simulate and construct transactions earlier → preserve more time for transaction submission.

A low-latency feed cannot guarantee transaction success or strategy profitability. However, when strategy, fee, and execution conditions are comparable, earlier state gives a trading system a larger reaction window, improves its competitiveness in latency races, and increases its opportunity to capture potential revenue.

## Benchmark Methodology

### Test regions and subjects

We deployed a benchmark client in each of three AWS US East (Ohio) Availability Zones:

- `use2-az1`
- `use2-az2`
- `use2-az3`

Each client established two WSS connections and received data from:

- BlockRazor Robinhood Chain Sequencer Feed Ultra (`/ws/ultra`)
- Robinhood Chain official Sequencer Feed (wss://feed.mainnet.chain.robinhood.com)

Receiving both feeds on the same server gave the compared feeds the same client environment and local network conditions, reducing the effect of deployment differences. Testing three Availability Zones also showed whether the direction of the result remained consistent across different network paths within the same region.

The October 2, 2026 dataset contains **2,984 matching samples in `use2-az1`**, **2,945 in `use2-az2`**, and **2,982 in `use2-az3`**, for **8,911 matching blocks in total**. The test can be reproduced with BlockRazor's open-source [robinhood-feed-speed benchmark tool](https://github.com/BlockRazorinc/robinhood-feed-speed).

### Test procedure

1. Connect to BlockRazor Feed and the official feed simultaneously from the same test server in each Availability Zone.
2. Receive and parse the block data pushed by both feeds.
3. Match identical blocks received from the two feeds.
4. Record the arrival timestamp of each matching block from each feed.
5. Assign a relative latency of `0 ms` to the feed that arrives first.
6. Assign the later feed a relative latency equal to the difference between the two arrival timestamps.
7. Calculate P50, P90, P95, P99, and maximum relative latency for each feed.

This benchmark measures the **relative arrival time for identical blocks delivered by two feeds to the same client**. A value of `0 ms` therefore means that a feed arrived first for the corresponding sample. It does not mean that the end-to-end latency from the sequencer to the client was zero.

## Benchmark Results

### P99 relative latency remained at 0 ms in all three Availability Zones

| AWS AZ | Timestamp | Samples | Sequencer Feed | P50 | P90 | P95 | P99 | Max |
| --- | --- | ---: | --- | ---: | ---: | ---: | ---: | ---: |
| use2-az1 | 2026/10/02 07:49:57 | 2,984 | **BlockRazor Ultra** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** |
| use2-az1 | 2026/10/02 07:49:57 | 2,984 | Robinhood official feed | 7.449 ms | 9.086 ms | 9.644 ms | 17.949 ms | 474.037 ms |
| use2-az2 | 2026/10/02 07:50:13 | 2,945 | **BlockRazor Ultra** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** |
| use2-az2 | 2026/10/02 07:50:13 | 2,945 | Robinhood official feed | 30.732 ms | 41.094 ms | 58.442 ms | 104.372 ms | 493.632 ms |
| use2-az3 | 2026/10/02 07:50:09 | 2,982 | **BlockRazor Ultra** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** | **0.000 ms** |
| use2-az3 | 2026/10/02 07:50:09 | 2,982 | Robinhood official feed | 27.053 ms | 28.322 ms | 31.812 ms | 61.687 ms | 459.429 ms |

BlockRazor maintained `0.000 ms` relative latency through P99 in all three Availability Zones, and its maximum relative latency also remained at `0.000 ms` in every zone. The consistent result across all three zones shows that the delivery advantage was not confined to a single AZ or network path.

### Earlier state updates and a more stable reaction window

The official feed recorded median relative latency of **7.449 ms** in `use2-az1`, **30.732 ms** in `use2-az2`, and **27.053 ms** in `use2-az3`. The difference became larger in the tail: its P99 reached **17.949 ms**, **104.372 ms**, and **61.687 ms**, respectively. The largest maximum gap appeared in `use2-az2`, where the official feed's maximum relative latency reached **493.632 ms**.

For node operators, lower tail latency can reduce temporary state lag caused by feed jitter and help local state follow the sequencer more closely. For searchers, trading bots, and automated trading systems, earlier state enables earlier detection, opportunity evaluation, simulation, and transaction construction, preserving more time for submission.

For searchers and quant trading systems, this benchmark evaluates the timing of block-data delivery, not the profitability of a strategy. The [Robinhood Chain product page](https://blockrazor.io/products/robinhood/) explains the available feed modes, while the [Robinhood Chain RPC benchmark](https://blockrazor.io/blog/RobinhoodChainRPC/) evaluates the separate transaction-submission stage. Transaction success still depends on strategy validity, submission speed, fee configuration, competitors, and onchain execution. When other conditions are comparable, however, an earlier and more stable Sequencer Feed shortens the total reaction time from state update to transaction submission, improves the probability of winning competitive execution, and substantially increases the opportunity to capture potential revenue.

## Getting Started

BlockRazor Sequencer Feed Ultra is compatible with the standard feed interface used by Robinhood Nitro nodes. Operators can connect over WSS by updating `--node.feed.input.url` in the startup configuration.

If your team operates a Robinhood Chain node, searcher, trading bot, or other real-time trading system, review the [BlockRazor Sequencer Feed Ultra benchmark and integration guide](https://docs.blockrazor.io/streams/node-stream/robinhood-chain/sequencer-feed-ultra) and benchmark it from your own production environment.
