<p>BlockSec 推出 Phalcon Compliance 3.1，以实现更快速、易于访问的加密资产 KYT 筛查</p>
<p><strong>以搜索为先的架构以加快 KYT 筛查</strong></p>
<p>Phalcon Compliance 3.1 引入了一种重新设计的合规工作流程，通过允许用户立即开始筛查，降低了链上风险筛查（KYT/KYA）的初始门槛。在传统的合规系统中，KYT/KYA 筛查通常仅在注册、入职和预售流程（包括预定演示、完成 KYB 程序和最终确定商业协议）之后才开始。这些步骤可能会延迟在快速变化的链上环境中进行的时间敏感的反洗钱检查和对手方验证。</p>
<p>通过此次新发布，Phalcon Compliance 采用了 <strong>以搜索为先的架构</strong>，允许用户直接从产品的登录页面发起扫描。用户只需输入钱包地址或交易哈希，即可立即访问合规结果，<strong>无需创建账户或完成入职</strong>，在速度至关重要时能够更快地访问合规工具。</p>
<p>Phalcon Compliance 3.1 还引入了统一的主页，将多链搜索、风险趋势洞察、筛查历史和示例数据集整合在一个界面中。内置的示例数据，包括加拿大涉嫌贩毒者和前奥运滑雪板运动员 Ryan James WEDDING，使新用户能够在 <strong>提交任何数据或设置账户之前</strong> 探索平台功能。</p>
<p><strong>即时风险评估的轻量扫描</strong></p>
<p>虽然以搜索为先的架构消除了开始扫描的障碍，但许多现实场景也需要在不承诺全额订阅的情况下立即访问风险结论。例如，交易所支持团队可能需要快速验证提款目的地，或者个人用户可能希望在发送资金之前检查收款地址。在这些情况下，订阅要求造成的延迟可能会减缓决策过程并增加操作风险。</p>
<p>为满足这一需求，Phalcon Compliance 3.1 引入了轻量扫描模式，使用户能够查看 <strong>核心风险筛查结果，而无需订阅完整平台</strong>。用户可以提交钱包地址或交易哈希，立即访问基本风险指标，支持快速的初步评估。</p>
<p>轻量筛查结果包括核心风险标签，如制裁暴露、诈骗参与、人贩子活动或与混合器相关的活动，以及基本财务指标和对高风险实体的暴露指标。通过关注关键风险信号而非完整的调查细节，轻量扫描能够在尚未需要全面调查的情况下加快决策过程。</p>
<p><strong>灵活的信用系统和扩展的支付选项</strong></p>
<p>Phalcon Compliance 3.1 引入了一种更灵活的基于信用的使用模型，旨在满足具有波动的 KYT 筛查量的组织，以及寻求可预测合规成本的个人和初创团队。用户无需承诺固定的订阅层级，而是可以根据需要购买所需的筛查信用，减少在低活动期间的未使用容量，同时在需求较高的时期保留扩大筛查活动的能力。</p>
<p>此次更新还扩展了可用的支付选项，以适应不同地区的用户。国内用户现在可以通过微信支付购买信用，而国际用户则可以使用 Cash App 作为额外的支付方式。现有的选项，包括信用卡和加密货币支付，仍然得到支持。根据 BlockSec 的说法，扩展的支付支持旨在降低访问专业区块链合规基础设施的地理和操作障碍。</p>
<p><strong>满足全球监管期望</strong></p>
<p>Phalcon Compliance 3.1 扩大了平台支持符合 FATF 要求的了解您的交易（KYT）要求和广泛的区域监管义务的能力。该系统维护着超过 4 亿个标记的区块链地址的数据库，并支持在包括以太坊、Tron、BSC、Polygon、Base 和 Optimism 等主要网络上的筛查。</p>
<p>该平台的毫秒级 API 性能支持高频、实时的筛查工作流程，同时与 MetaSleuth（BlockSec 的加密资金流追踪和调查平台）的集成支持可视化资金流分析和调查用例。Phalcon Compliance 3.1 还支持一键生成可疑交易报告（STR），使报告工作流程与国际监管标准保持一致。</p>
<p>BlockSec 报告称，Phalcon Compliance 和 MetaSleuth 平台目前在全球拥有超过 500 个客户，包括 Coinbase 和 Bybit 等加密货币交易所，以及联合国、FBI 和证券及期货事务监察委员会（SFC）等公共部门和监管机构。</p>
<p><strong>支持生态系统采用的推荐计划</strong></p>
<p>BlockSec 推出了一项推荐计划，伴随 Phalcon Compliance 3.1 的发布，旨在降低自助反洗钱合规工具的访问成本，并鼓励更广泛的生态系统采用。该计划为每位新用户提供三次扫描积分。</p>
<p>除了扫描积分外，推荐计划还包括现金返还组件，提供高达 20% 的奖励，适用于被推荐用户的支付。现金返还收益在达到 100 美元后可提取，每位参与者的终身上限为 10,000 美元。根据 BlockSec 的说法，该倡议旨在支持早期团队、独立从业者和较小组织在开始或扩展其合规工作流程时。</p>
<p><strong>开始推荐之旅</strong></p>
<p><strong>可用性</strong></p>
<p>Phalcon Compliance 3.1 现已向所有用户开放。</p>
<p><strong>Phalcon Compliance 3.1 现已可用</strong> - 能够在几秒钟内开始筛查</p>

<div class="lb-trans"><p>BlockSec 推出 Phalcon Compliance 3.1，以实现更快速、易于访问的加密资产 KYT 筛查</p>
</div><p><strong>Search-First Architecture for Faster KYT Screening</strong></p>
<div class="lb-trans"><p><strong>以搜索为先的架构以加快 KYT 筛查</strong></p>
</div><p>Phalcon Compliance 3.1 introduces a redesigned compliance workflow that lowers the initial barrier to on-chain risk screening (KYT/KYA) by allowing users to start screening immediately. In traditional compliance systems, KYT/KYA screening typically begins only after after registration, onboarding, and pre-sales processes, including booking demonstrations, completing KYB procedures, and finalizing commercial agreements. These steps can delay time-sensitive AML checks and counterparty verification in fast-moving on-chain environments.</p>
<div class="lb-trans"><p>Phalcon Compliance 3.1 引入了一种重新设计的合规工作流程，通过允许用户立即开始筛查，降低了链上风险筛查（KYT/KYA）的初始门槛。在传统的合规系统中，KYT/KYA 筛查通常仅在注册、入职和预售流程（包括预定演示、完成 KYB 程序和最终确定商业协议）之后才开始。这些步骤可能会延迟在快速变化的链上环境中进行的时间敏感的反洗钱检查和对手方验证。</p>
</div><p>With the new release, Phalcon Compliance adopts a <strong>Search-First Architecture</strong> that allows users to initiate scans directly from the product's landing page. By entering a wallet address or transaction hash, users can immediately access compliance results <strong>without creating an account or completing onboarding</strong>, enabling faster access to compliance tools when speed is critical.</p>
<div class="lb-trans"><p>通过此次新发布，Phalcon Compliance 采用了 <strong>以搜索为先的架构</strong>，允许用户直接从产品的登录页面发起扫描。用户只需输入钱包地址或交易哈希，即可立即访问合规结果，<strong>无需创建账户或完成入职</strong>，在速度至关重要时能够更快地访问合规工具。</p>
</div><p>Phalcon Compliance 3.1 also introduces a unified Home Page that brings together multi-chain search, risk trend insights, screening history, and sample datasets in a single interface. Built-in sample data, including the Canadian alleged drug trafficker and former Olympic snowboarder Ryan James WEDDING, allows new users to explore platform capabilities <strong>before committing any data or setting up an account</strong>.</p>
<div class="lb-trans"><p>Phalcon Compliance 3.1 还引入了统一的主页，将多链搜索、风险趋势洞察、筛查历史和示例数据集整合在一个界面中。内置的示例数据，包括加拿大涉嫌贩毒者和前奥运滑雪板运动员 Ryan James WEDDING，使新用户能够在 <strong>提交任何数据或设置账户之前</strong> 探索平台功能。</p>
</div><p><strong>Lite Scan for Instant Risk Assessment</strong></p>
<div class="lb-trans"><p><strong>即时风险评估的轻量扫描</strong></p>
</div><p>While the Search-First Architecture removes barriers to starting a scan, many real-world scenarios also require immediate access to risk conclusions without committing to a full subscription. For example, an exchange support team may need to quickly validate a withdrawal destination, or an individual user may want to check a recipient address before sending funds. In these cases, delays caused by subscription requirements can slow decision-making and increase operational risk.</p>
<div class="lb-trans"><p>虽然以搜索为先的架构消除了开始扫描的障碍，但许多现实场景也需要在不承诺全额订阅的情况下立即访问风险结论。例如，交易所支持团队可能需要快速验证提款目的地，或者个人用户可能希望在发送资金之前检查收款地址。在这些情况下，订阅要求造成的延迟可能会减缓决策过程并增加操作风险。</p>
</div><p>To address this need, Phalcon Compliance 3.1 introduces Lite Scan Mode which enables users to view <strong>core risk screening results without subscribing to the full platform</strong>. Users can submit a wallet address or transaction hash and immediately access essential risk indicators, supporting rapid first-pass assessments.</p>
<div class="lb-trans"><p>为满足这一需求，Phalcon Compliance 3.1 引入了轻量扫描模式，使用户能够查看 <strong>核心风险筛查结果，而无需订阅完整平台</strong>。用户可以提交钱包地址或交易哈希，立即访问基本风险指标，支持快速的初步评估。</p>
</div><p>The lite screening results include core risk labels, such as sanctions exposure, scam involvement, human trafficking, or mixer-related activity, alongside basic financial metrics and indicators of exposure to high-risk entities. By focusing on critical risk signals rather than full investigative detail, Lite Scan enables faster decision-making in scenarios where a complete investigation is not yet required.</p>
<div class="lb-trans"><p>轻量筛查结果包括核心风险标签，如制裁暴露、诈骗参与、人贩子活动或与混合器相关的活动，以及基本财务指标和对高风险实体的暴露指标。通过关注关键风险信号而非完整的调查细节，轻量扫描能够在尚未需要全面调查的情况下加快决策过程。</p>
</div><p><strong>Flexible Credit System and Expanded Payment Options</strong></p>
<div class="lb-trans"><p><strong>灵活的信用系统和扩展的支付选项</strong></p>
</div><p>Phalcon Compliance 3.1 introduces a more flexible credit-based usage model aimed at organizations with fluctuating KYT screening volumes, as well as individuals and early-stage teams seeking predictable compliance costs. Rather than committing to fixed subscription tiers, users can purchase only the number of screening credits required at a given time, reducing unused capacity during low-activity periods while retaining the ability to scale screening activity during periods of higher demand.</p>
<div class="lb-trans"><p>Phalcon Compliance 3.1 引入了一种更灵活的基于信用的使用模型，旨在满足具有波动的 KYT 筛查量的组织，以及寻求可预测合规成本的个人和初创团队。用户无需承诺固定的订阅层级，而是可以根据需要购买所需的筛查信用，减少在低活动期间的未使用容量，同时在需求较高的时期保留扩大筛查活动的能力。</p>
</div><p>The update also expands available payment options to accommodate users in different regions. Domestic users can now purchase credits through WeChat Pay, while international users have access to Cash App as an additional payment method. Existing options, including credit card and cryptocurrency payments, remain supported. According to BlockSec, the expanded payment support is intended to lower geographic and operational barriers for accessing professional blockchain compliance infrastructure.</p>
<div class="lb-trans"><p>此次更新还扩展了可用的支付选项，以适应不同地区的用户。国内用户现在可以通过微信支付购买信用，而国际用户则可以使用 Cash App 作为额外的支付方式。现有的选项，包括信用卡和加密货币支付，仍然得到支持。根据 BlockSec 的说法，扩展的支付支持旨在降低访问专业区块链合规基础设施的地理和操作障碍。</p>
</div><p><strong>Meeting Global Regulatory Expectations</strong></p>
<div class="lb-trans"><p><strong>满足全球监管期望</strong></p>
</div><p>Phalcon Compliance 3.1 expands the platform's ability to support FATF-aligned Know Your Transaction (KYT) requirements and a wide range of regional regulatory obligations. The system maintains a database of more than 400 million labeled blockchain addresses and supports screening across major networks including Ethereum, Tron, BSC, Polygon, Base, and Optimism.</p>

</div><p>The platform's millisecond-level API performance enables high-frequency, real-time screening workflows, while its integration with MetaSleuth, BlockSec's crypto fund flow tracking and investigation platform, supports visual fund-flow analysis and investigative use cases. Phalcon Compliance 3.1 also enables one-click generation of Suspicious Transaction Reports (STRs), aligning reporting workflows with international regulatory standards.</p>

</div><p>BlockSec reports that the Phalcon Compliance and MetaSleuth platform is currently used by more than 500 clients worldwide, including cryptocurrency exchanges such as Coinbase and Bybit, as well as public-sector and regulatory organizations including the United Nations, the FBI, and the Securities and Futures Commission (SFC).</p>

</div><p><strong>Referral Program Supporting Ecosystem Adoption</strong></p>
<div class="lb-trans"><p><strong>支持生态系统采用的推荐计划</strong></p>
</div><p>BlockSec has introduced a referral program alongside the Phalcon Compliance 3.1 release, aimed at lowering the cost of access to self-service AML compliance tools and encouraging broader ecosystem adoption. The program provides participants with three scanning credits for each new user.</p>
<div class="lb-trans"><p>BlockSec 推出了一项推荐计划，伴随 Phalcon Compliance 3.1 的发布，旨在降低自助反洗钱合规工具的访问成本，并鼓励更广泛的生态系统采用。该计划为每位新用户提供三次扫描积分。</p>
</div><p>In addition to scanning credits, the referral program includes a cashback component that offers up to 20% rewards on payments made by referred users. Cashback earnings become withdrawable once they reach 100 USD, with a lifetime cap of 10,000 USD per participant. According to BlockSec, the initiative is intended to support early-stage teams, independent practitioners, and smaller organizations as they begin or scale their compliance workflows.</p>
