Overlay Networks：擴展 BSV 區塊鏈的交易驗證

隨著區塊鏈處理越來越多的交易，企業需要有效的方法來驗證與其營運相關的交易的有效性。 Overlays 是一種利用 Merkle Paths 和簡單支付驗證 (SPV) 的服務，使企業能夠維護自己的未花費交易輸出 (UTXO) 子集，從而提供可擴展的解決方案。與全域監聽方法相比，這種方法顯著降低了資料處理要求，並使企業能夠專注於直接影響其營運的事務。

Overlay Networks: The Key to Scalable Transaction Verification on the BSV Blockchain

覆蓋網路：BSV 區塊鏈上可擴展交易驗證的關鍵

The BSV blockchain, with its unparalleled transaction processing capabilities, poses a unique challenge: how to efficiently verify and categorize the vast number of transactions it processes every second. Global listening, the current method employed by some businesses to monitor all transactions, has its limitations. As the network scales exponentially with Teranode, the bandwidth and computational resources required for global listening become prohibitively expensive.

BSV 區塊鏈以其無與倫比的交易處理能力提出了獨特的挑戰：如何有效地驗證和分類其每秒處理的大量交易。全球監聽是一些企業目前採用的監控所有交易的方法，但有其限制。隨著 Teranode 網路呈指數級擴展，全域監聽所需的頻寬和運算資源變得異常昂貴。

Enter Overlay Networks, a revolutionary approach that empowers businesses to focus only on transactions relevant to their operations. By leveraging Simple Payment Verification (SPV) and Merkle Paths instead of full block data, Overlays dramatically reduce the data overhead involved in transaction validation. Imagine a business that processes one transaction every 10 minutes (573 bytes). With global listening, it would have to sift through 340,000,000,000 bytes of information. With SPV, that's reduced to a mere 1,537 bytes—a staggering 221 million times more efficient at Teranode scale.

Overlay Networks 是一種革命性的方法，使企業能夠只專注於與其營運相關的交易。透過利用簡單支付驗證 (SPV) 和 Merkle 路徑而不是完整的區塊數據，疊加層極大地減少了交易驗證中涉及的數據開銷。想像一下，一家企業每 10 分鐘（573 位元組）處理一筆交易。如果進行全域監聽，則必須篩選 340,000,000,000 位元組的資訊。借助 SPV，該大小減少至僅 1,537 字節，在 Teranode 規模上效率提高了 2.21 億倍，令人震驚。

How Overlays Work

疊加層的工作原理

Overlays maintain their own subsets of unspent transaction outputs (UTXOs), allowing them to ignore irrelevant transactions. This specialization enables businesses to focus their resources on what matters most, without wasting time and effort on unrelated data. SPV uses Merkle proofs to determine whether a transaction has been included in a block, using only data from the Block Header, significantly reducing the amount of data that needs to be processed.

覆蓋層維護自己的未花費交易輸出（UTXO）子集，允許它們忽略不相關的交易。這種專業化使企業能夠將資源集中在最重要的事情上，而無需在不相關的數據上浪費時間和精力。 SPV 使用 Merkle 證明來確定交易是否已包含在區塊中，僅使用區塊頭中的數據，顯著減少了需要處理的數據量。

Identifying Transaction Types

識別交易類型

To categorize UTXOs, Overlays rely on various methods, such as data contained in simple OP_RETURN or tagging metadata. ProjectBabbage's Confederacy Lookup Services is an example of how Overlays identify specific UTXO types based on "Topics," feeding them into custom data stores. This allows for efficient data categorization and distribution across multiple hosts.

為了對 UTXO 進行分類，Overlays 依賴各種方法，例如簡單 OP_RETURN 中包含的資料或標記元資料。 ProjectBabbage 的 Confederacy Lookup Services 是一個範例，展示了 Overlays 如何根據「主題」識別特定的 UTXO 類型，並將其輸入自訂資料儲存中。這允許跨多個主機進行有效的資料分類和分發。

Benefits of Overlays

疊加的好處

Overlays offer numerous benefits, including:

覆蓋層提供了許多好處，包括：

• Increased Efficiency: By focusing only on relevant transactions, businesses can significantly reduce the data overhead associated with transaction verification.
• Cost Savings: Overlays eliminate the need for global listening, reducing bandwidth and computational resource consumption, leading to substantial cost savings.
• Scalability: Overlays are essential for the scalability of the BSV blockchain, enabling efficient transaction processing even as the network grows exponentially.
• Specialization: Overlays allow for greater specialization within the blockchain industry, with miners/nodes ensuring network security and Overlays providing a service layer for applications to share context and retrieve relevant UTXO subsets.
