Overlay Networks：扩展 BSV 区块链的交易验证

随着区块链处理越来越多的交易，企业需要有效的方法来验证与其运营相关的交易的有效性。 Overlays 是一种利用 Merkle Paths 和简单支付验证 (SPV) 的服务，使企业能够维护自己的未花费交易输出 (UTXO) 子集，从而提供可扩展的解决方案。与全局监听方法相比，这种方法显着降低了数据处理要求，并使企业能够专注于直接影响其运营的事务。

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

覆盖网络：BSV 区块链上可扩展交易验证的关键

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 区块链以其无与伦比的交易处理能力提出了独特的挑战：如何有效地验证和分类其每秒处理的大量交易。全球监听是一些企业目前采用的监控所有交易的方法，但有其局限性。随着 Teranode 网络呈指数级扩展，全局监听所需的带宽和计算资源变得异常昂贵。

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 是一种革命性的方法，使企业能够只关注与其运营相关的交易。通过利用简单支付验证 (SPV) 和 Merkle 路径而不是完整的块数据，叠加层极大地减少了交易验证中涉及的数据开销。想象一下，一家企业每 10 分钟（573 字节）处理一笔交易。如果进行全局监听，则必须筛选 340,000,000,000 字节的信息。借助 SPV，该大小减少至仅 1,537 字节，在 Teranode 规模上效率提高了 2.21 亿倍，令人震惊。

How Overlays Work

叠加层的工作原理

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.

覆盖层维护自己的未花费交易输出（UTXO）子集，允许它们忽略不相关的交易。这种专业化使企业能够将资源集中在最重要的事情上，而无需在不相关的数据上浪费时间和精力。 SPV 使用 Merkle 证明来确定交易是否已包含在区块中，仅使用区块头中的数据，显着减少了需要处理的数据量。

Identifying Transaction Types

识别交易类型

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.

为了对 UTXO 进行分类，Overlays 依赖于各种方法，例如简单 OP_RETURN 中包含的数据或标记元数据。 ProjectBabbage 的 Confederacy Lookup Services 是一个示例，展示了 Overlays 如何根据“主题”识别特定的 UTXO 类型，并将其输入自定义数据存储中。这允许跨多个主机进行有效的数据分类和分发。

Benefits of Overlays

叠加的好处

Overlays offer numerous benefits, including:

覆盖层提供了许多好处，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.

Conclusion

提高效率：通过仅关注相关交易，企业可以显着减少与交易验证相关的数据开销。节省成本：覆盖消除了全局监听的需要，减少了带宽和计算资源消耗，从而节省了大量成本。可扩展性：覆盖是对于 BSV 区块链的可扩展性至关重要，即使网络呈指数级增长，也能实现高效的交易处理。专业化：覆盖允许区块链行业内实现更大的专业化，矿工/节点确保网络安全，覆盖为应用程序提供共享上下文的服务层并检索相关的UTXO子集。结论

Overlay Networks are a transformative technology that will play a pivotal role in the future of the BSV blockchain. By providing businesses with the ability to focus on relevant transactions while ignoring the noise, Overlays enable efficient and scalable transaction verification. As the BSV blockchain continues to grow and evolve, Overlays will become indispensable for maintaining a functioning, blockchain/Web3-based digital economy.

Overlay Networks 是一项变革性技术，将在 BSV 区块链的未来中发挥关键作用。通过让企业能够专注于相关交易而忽略噪音，覆盖可以实现高效且可扩展的交易验证。随着 BSV 区块链的不断发展和发展，Overlays 将成为维持功能性、基于区块链/Web3 的数字经济不可或缺的一部分。
