BSC NewBlocks Stream API

瞭解 BlockRazor BSC Block Stream的服務、應用場景、Benchmark、價格、端點以及集成方法

BSC NewBlocks是什麼

NewBlocks 是 BlockRazor 提供的高性能區塊數據流服務，用於低延遲訂閱鏈上最新區塊與已確認交易。NewBlocks 幫助用戶更早接收到最新區塊內容，並將其中的區塊頭、交易列表和後續出塊者信息，以更低延遲接入自己的監控或策略系統。

NewBlocks 基於 BEF 分發最新區塊數據。當區塊在網絡中產生並開始傳播時，BlockRazor 會在多個核心區域盡早接收區塊，再通過低延遲鏈路轉發給訂閱方，縮短用戶接收區塊數據的時間。

BSC NewBlocks的應用場景

• Confirmed交易監控： 實時接收最新區塊中的已確認交易，用於監控目標地址、熱門合約或異常交易行為

• 區塊級數據分析： 獲取區塊頭、交易列表與後續出塊者信息，用於區塊研究、節點觀測與網絡狀態分析

• 策略數據輸入： 作為交易系統的 confirmed 數據源，與 Public Mempool、Transaction Submission 等能力配合使用，構建更完整的監控與執行鏈路

Benchmark

在接收新區塊的延遲測試中，我們分別在 Dublin、Frankfurt、Tokyo 和 Virginia 四個區域，對 BlockRazor 與普通 Node 進行了對比。評估方式基於雙方對同一區塊的接收時間差，統計在可比樣本中由哪一方更早收到新區塊。

Region	BlockRazor Lead Rate	Avg Lead	P50 Lead	P90 Lead
Dublin	100.0%	60.4 ms	50.5 ms	90.7 ms
Frankfurt	100.0%	61.5 ms	54.7 ms	92.3 ms
Tokyo	100.0%	239.1 ms	145.7 ms	622.9 ms
Virginia	99.5%	69.0 ms	58.3 ms	121.6 ms

從結果來看，BlockRazor 在四個區域均表現出穩定領先。Frankfurt、Tokyo 和 Dublin 三個區域中，BlockRazor 的領先率均達到 100%；Virginia 區域的領先率也達到 99.5%。從領先幅度看，BlockRazor 在不同區域的平均領先時間約為 60.4 ms、61.5 ms、239.1 ms 和 69.0 ms；在 P90 維度下，領先幅度分別達到 90.7 ms、92.3 ms、622.9 ms 和 121.6 ms。

這表明在新區塊到達這一關鍵鏈路上，BlockRazor 能夠更穩定地搶先於普通 Node 接收到區塊數據。
