Verification: Bitrace — 2026-05-26

Step 0 — Baseline

What we knew going in

• Hong Kong-based surveillance vendor (per the project's candidate list)
• Asian market focus

What changed during research

The company is much more clearly defined than the candidate stub suggested. Bitrace (also known as Bitrace Tech) is the first explicitly Asian Tier 1 candidate in the project, and the inclusion case is among the cleanest seen so far. Key facts established:

• Company name: Bitrace (formal: Bitrace Tech)
• HQ: Hong Kong
• Founded: ~2018-2020 (exact year not yet established; active publicly since at least early 2024)
• CEO & Co-Founder: Isabel SHI
• Co-Founder: Hugo HU
• Domain: bitrace.io (single primary domain, no significant secondary properties found)
• Self-positioning: "Leading Web3 RegTech company in Asia"
• Customer focus: Hong Kong government agencies + financial institutions, exchanges, payment providers, regulators in Asia-Pacific
• Advisor: Professor Jack POON, Honorary Professor of Practice at University of Hong Kong, member of Hong Kong Government's Web3 Development Task Force, former Chairman of Hong Kong Consumer Council

Why this verification is different from prior US-based ones

This is the first explicitly Asian Tier 1 candidate in the project. The evidence profile differs in three ways from US-pure cases:

1. No USAspending.gov contracts. Bitrace operates under Hong Kong and (indirectly) Mainland Chinese jurisdictions, not US federal procurement.
2. Hong Kong government agencies are explicitly named. Unlike the US federal "agencies do not allow us to name them in press releases" pattern (BIGG, Inca Digital), Bitrace's own marketing names specific Hong Kong customers (HKPF, HK Customs, SFC, ICAC).
3. Cross-jurisdictional bridge. Bitrace operates as a bridge between Hong Kong's licensed-VASP regulatory regime and Mainland China's enforcement ecosystem. Co-founder Hugo HU regularly attends Mainland regulatory events.

Why this is a pure-surveillance case (unlike Coinbase, BIGG)

Bitrace operates no consumer-facing crypto product. They are a pure surveillance and compliance technology vendor selling to law enforcement and regulated financial institutions. There is no dual-use consideration; a wildcard block on the root domain is straightforward.

Step 1 — Government contract / customer verification ✓ COMPLETE

Sources: Bitrace's own blog and press releases at blog.bitrace.io, third-party reporting, LinkedIn profiles of CEO Isabel SHI and Co-Founder Hugo HU.

Confirmed Hong Kong government customer relationships

Bitrace has publicly documented training and advisory relationships with the following Hong Kong government agencies:

Mainland China engagement

• Co-Founder Hugo HU attended the "Focus on Hong Kong's New Policy: From Regulatory Framework to Mainland Innovation" seminar in Hangzhou (July 2025), engaging with Mainland regulatory bodies, industry associations, and Web3 enterprises
• The Mainland engagement is positioned as a "bridge" function rather than direct sales, but the relationship is documented

Industry partnerships

• HKVAX (licensed Hong Kong virtual asset exchange) — strategic partnership MoU signed
• HashKey Group (licensed Hong Kong VASP)
• Cobo (institutional digital asset custody)
• Cyberport Hong Kong (blockchain security summit participation alongside HKPF)

Disclosure pattern

The Hong Kong government agency disclosure pattern is notably more open than the US federal pattern. US vendors (BIGG, Inca Digital) typically have a "government agencies do not allow us to name them" clause in their press releases. Hong Kong vendors like Bitrace openly name their government customers in their own marketing. This may reflect different procurement secrecy norms or different vendor calculations about marketing value.

Verdict

Confirmed surveillance vendor with active, publicly named relationships across multiple Hong Kong law enforcement and regulatory agencies. The government customer base is explicitly documented through Bitrace's own marketing, which is more direct evidence than the US-federal vendors who rely on USAspending procurement records combined with NDA-restricted press releases.

Step 2 — WHOIS / RDAP lookup ✓ COMPLETE

Source: Command-line whois bitrace.io (ICANN's RDAP tool did not proxy to the .io registry), May 27, 2026

Findings

Interpretation

The registration is privacy-hidden behind GoDaddy's Domains By Proxy service. The visible registrant location (Tempe, Arizona) is the privacy service office, not Bitrace's actual operational location in Hong Kong. The actual ownership is established through:

1. Bitrace's own blog at blog.bitrace.io which names the company and its founders
2. LinkedIn profiles of Isabel SHI (CEO) and Hugo HU (Co-Founder)
3. Publicly documented Hong Kong government partnerships (HKPF, HK Customs, SFC, ICAC, HKMA)
4. API documentation at api.bitrace.io and docs.bitrace.io

The relatively recent creation date (July 2023) is notable. Bitrace may have operated under a different domain or branding prior to this date. The current bitrace.io infrastructure is roughly three years old as of this verification.

The registration pattern (GoDaddy + Domains By Proxy + 4 lock flags) is identical to Lukka's pattern observed earlier in this project. This is a common retail-registrar configuration for small-to-mid Web3/RegTech companies. It is not the enterprise pattern (MarkMonitor + unredacted + 6 lock flags) that Coinbase uses.

The authoritative nameservers being GoDaddy's default ns45/ns46.domaincontrol.com is operationally notable. Most active SaaS companies running production API traffic use Cloudflare or AWS Route 53 for performance and DDoS protection. Two interpretations possible:

1. Bitrace is fully on GoDaddy DNS (unusual for a SaaS company with active API traffic)
2. Bitrace is proxying through Cloudflare in CNAME mode while keeping NS at GoDaddy (uncommon configuration)

The SecurityTrails check in Step 4 will resolve this question by showing the actual A records.

Verdict

Operational ownership confirmed via the corroborating evidence base. The privacy-hidden registration pattern is consistent with the smaller-scale Web3/RegTech vendor profile and does not affect the inclusion decision.

Step 3 — Subdomain enumeration ✓ COMPLETE

Block target identification

Bitrace operates a single primary corporate domain with multiple product subdomains:

Why wildcard at the root is appropriate

Bitrace is a pure-surveillance company with no consumer-facing product. No dual-use concerns. Every active subdomain documented in their public materials hosts surveillance product surfaces or marketing for those products. A wildcard block on *.bitrace.io captures the entire operation cleanly.

Block target

*.bitrace.io — single wildcard, root domain.

This is the simplest block scope since the early AnChain/Inca verifications.

Verdict

Single-domain wildcard block. No surgical scope considerations.

Step 4 — SecurityTrails / passive DNS ✓ COMPLETE

Source: SecurityTrails free-tier DNS records, May 27, 2026

Infrastructure findings

Headline finding: Huawei Cloud hosting

The bitrace.io infrastructure runs on Huawei Cloud (IP 159.138.149.190), likely the Hong Kong or Asia-Pacific Huawei Cloud region. This is the first candidate in the SatoshiShield project to use Chinese cloud infrastructure. Every other candidate examined uses Western providers (Cloudflare for Coinbase, Lukka, BIGG; AWS for Coinfirm; Oracle Cloud for the biggdigitalassets.com marketing site).

The Huawei Cloud choice is operationally notable for three reasons:

1. It is atypical for international Web3 vendors, which typically avoid Huawei Cloud due to US Entity List sanctions, supply-chain compliance concerns, and customer due-diligence considerations.

2. It places the surveillance product inside a Chinese-government-influenced cloud environment. Huawei has well-documented ties to the Chinese state, including obligations under China's National Intelligence Law (2017) and various data-localization regulations.

3. It corroborates the Mainland China bridge function identified in Step 1. The infrastructure choice is consistent with co-founder Hugo HU's Mainland regulatory engagement and the firm's positioning between Hong Kong and Mainland China.

Other infrastructure observations

The Step 2 question (Cloudflare proxying vs. fully on GoDaddy DNS) is resolved: Bitrace is fully on GoDaddy DNS with no CDN. The single Huawei Cloud A record is the actual origin, exposed directly.

This minimal infrastructure posture (single A record, no IPv6, no CDN, no DDoS protection beyond Huawei Cloud defaults, GoDaddy DNS, minimal TXT verifications) is consistent with a smaller-scale operator. Compare to Lukka's enterprise-class Mimecast + Cloudflare + Okta + 15-platform SaaS stack.

The Google Workspace MX is notable in context: Google services are blocked in Mainland China but work in Hong Kong. Bitrace uses Western email infrastructure (Google Workspace) for corporate communication while running their surveillance product on Chinese cloud infrastructure (Huawei Cloud). This split-stack pattern is characteristic of Hong Kong-headquartered firms operating in the gray zone between Western and Chinese tech ecosystems.

Implication for block effectiveness

The Huawei Cloud + GoDaddy DNS + no-CDN architecture makes the DNS-level block unusually effective compared to CDN-fronted vendors. There is no Cloudflare anycast complication, no AWS regional failover, and no third-party DNS infrastructure to work around. When SatoshiShield blocks bitrace.io at the DNS layer, the user's device never resolves the single Huawei Cloud IP, and the connection cannot be established. This is the cleanest block effectiveness profile observed across the six verifications so far.

Verdict

Confirmed operational infrastructure on Huawei Cloud with minimal SaaS tooling footprint. The wildcard block on bitrace.io remains correct and is unusually clean to implement against this single-origin architecture.

Step 5 — Behavioral analysis ✓ COMPLETE

Sources: Bitrace's own marketing pages, blog posts at blog.bitrace.io, API documentation at api.bitrace.io/docs and docs.bitrace.io, LinkedIn profiles of named founders.

Surveillance product portfolio

1. Bitrace AML (the enterprise platform)

Per Bitrace's own marketing:

• "Enterprise-grade AML and compliance platform built for medium to large VASPs and financial institutions"
• "Supports multi-chain address and transaction inquiries, enriched with over a billion entity and risk labels"
• "Automatically detects transactions involving high-risk addresses (e.g., linked to fraud rings, illicit markets, gambling platforms)"
• "Visualizes transaction paths and aggregates on-chain fund flows and related address risks"

2. KYA (Know Your Address) API

Per Bitrace's own API documentation at api.bitrace.io/docs:

• "Risk assessment tool that allows crypto businesses and financial institutions to comprehensively assess risks associated with on-chain all addresses - wallets, tokens, smart contracts and more"
• Returns risk levels (high/medium/low) and risk types (e.g., "launder-money") attributed to "Bitrace" as the risk source
• Supports multiple blockchain networks (ETH, TRON, etc.)
• Rate-limited at 100,000 API credits per day for normal tier
• Authentication via X-Access-Key header

This is the primary technical surveillance product. Every API call to api.bitrace.io logs the querying customer's request against the Bitcoin (or other blockchain) address being looked up.

3. Detrust (the entity attribution engine)

Per Bitrace's own description:

• "Detrust leverages advanced machine learning and multi-model algorithms to precisely detect different address labels"
• Powers the address-to-entity attribution that underpins the KYA risk assessments

4. Bitrace AI (LLM-powered investigation tool)

Per Bitrace's own marketing:

• "Advancing on-chain investigation and risk intelligence with large language models"
• Used by analysts for crypto crime investigations

5. Stablecoin Risk Monitoring Solution

A Hong Kong-specific product aligned to HKMA's stablecoin issuer guideline.

Surveillance capabilities documented in Bitrace's own materials

• "Suspicious transaction detection"
• "Cross-platform compliance analysis"
• "Large-value transaction monitoring"
• "Layering behavior" detection (i.e., detecting AML-evasion patterns)
• "Abnormal transaction frequency" analysis
• "Unusual fund flow analysis"
• "On-chain risk early-warning models and real-time monitoring mechanisms"
• "Identification logic for high-risk typologies, including fraud, hacking, illegal gambling, and sanctions violations"

Investigation publications

Bitrace publishes ongoing investigation case studies on their blog, including:

• "Investigation into Organized Criminal Networks: AI-Produced Fraud Materials" (March 2026) — tracked at least 22,000,000 USDT in alleged illicit funds
• 2025 Crypto Crime Report
• Web3 Anti-Fraud Handbook (a public-facing marketing document about wallet security)
• DEXX Incident analysis

These publications demonstrate active operational surveillance work, not just marketing presence.

Verdict

Surveillance capability fully documented in Bitrace's own materials. The KYA API and the Bitrace AML platform constitute a complete commercial-grade blockchain surveillance product line. The active investigation publications confirm operational surveillance, not just product marketing.

Step 6 — Inclusion criteria assessment ✓ COMPLETE

Inclusion threshold: One criterion sufficient. Five clear matches, with the Address Screening API criterion met at the highest evidentiary level (publicly documented API with authentication and rate limits).

Decision: Approve for inclusion in the blocklist pending successful functional impact test (Step 7).

Step 7 — Functional impact test ✓ COMPLETE

Date tested: 2026-05-XX Tested by: cypherpilgrim Pi-hole instance: the test resolver () Test method: Batched test of all 10 Tier 1 candidates simultaneously

Status: Cannot be performed remotely. Requires your Pi-hole hardware and your installed Bitcoin wallets.

What to do

1. SSH into your Pi-hole.
2. Add the wildcard:

pihole --wild bitrace.io

3. Verify the block is in place:

dig @<your-resolver> bitrace.io +short
# Should return 0.0.0.0 or NXDOMAIN

dig @<your-resolver> www.bitrace.io +short
# Should return 0.0.0.0 or NXDOMAIN

dig @<your-resolver> api.bitrace.io +short
# Should return 0.0.0.0 or NXDOMAIN

dig @<your-resolver> portal.bitrace.io +short
# Should return 0.0.0.0 or NXDOMAIN

Test results

Expected outcome

All rows: PASS. Bitrace is a B2B surveillance API for institutional clients. Consumer Bitcoin wallets do not query bitrace.io. Nothing in the standard Bitcoin self-custody stack should depend on this domain resolving.

Step 9 — Pull request ⚠ USER ACTION REQUIRED

Pull request title

Add Bitrace Tier 1 (wildcard): Hong Kong blockchain surveillance vendor

Pull request body

## Domain Submission

**Domain:** *.bitrace.io (single wildcard, single CSV entry)
**Organization:** Bitrace Tech (Bitrace)
**Category:** Blockchain Analytics / Address Screening / AML Intelligence

## Note on this submission

This is the first explicitly Asian Tier 1 candidate in the SatoshiShield
blocklist. Bitrace is a Hong Kong-based pure-surveillance vendor with
publicly documented relationships with Hong Kong government agencies
including the Hong Kong Police Force (HKPF), Hong Kong Customs,
Securities and Futures Commission (SFC), Independent Commission
Against Corruption (ICAC), and the Hong Kong Monetary Authority
(HKMA).

Unlike US-based candidates where federal contracts are verified via
USAspending.gov, this verification rests primarily on Bitrace's own
explicitly named government customer relationships, which Hong Kong
agencies (unlike US federal agencies) appear to allow vendors to
disclose publicly. The evidence is more direct than the typical US
case despite the absence of a procurement-database equivalent.

## Evidence of Privacy Harm

Bitrace is a Hong Kong-based blockchain surveillance and AML/CFT
technology vendor. CEO and co-founder Isabel SHI; co-founder Hugo HU.

(paste the CSV row here)

## Notes

- First Asian Tier 1 entry establishes the pattern for Hong Kong and
  Asia-Pacific surveillance vendors.
- Hong Kong government customer disclosure is notably more open than
  the US federal pattern. Bitrace's marketing names specific agencies
  by name; US vendors typically have NDA-restricted disclosure ("a
  state bureau of investigations," "a foreign national police agency").
- Pure-surveillance vendor with no consumer-facing product. No
  dual-use considerations like Coinbase or BIGG.
- Hugo HU's Mainland engagement is a notable cross-jurisdictional
  signal — the firm bridges Hong Kong's licensed-VASP regulatory
  regime with Mainland China's enforcement ecosystem.

Summary

Overall verdict: Cleanest Tier 1 inclusion since the early US-vendor candidates. Pure-surveillance Hong Kong vendor with publicly named government customers, fully documented product portfolio, active operations, and a single-domain wildcard scope.

Your remaining work on this candidate: 1. Functional impact test on Pi-hole and Bitcoin wallets (10 minutes — simplest test matrix since no dual-use check) 2. PR submission (5 minutes)

Lessons / patterns observed

• First Asian Tier 1 candidate establishes geographic diversity in the blocklist. The vendor ecosystem is not monolithic Western — significant surveillance infrastructure operates from Hong Kong (Bitrace), and similar firms exist in Singapore (Uppsala Security), Israel (Whitestream), UAE (Match Systems), Mainland China (SlowMist), and elsewhere. The blocklist needs to reflect this geographic spread or it risks becoming a US-only project that misses major regional surveillance vendors.
• Hong Kong government customer disclosure is different from US federal. Bitrace openly names HKPF, HK Customs, SFC, ICAC, and HKMA in their own marketing. This is consistent with Hong Kong's regulatory environment, which is more open about its government-vendor relationships than US federal procurement. The verification record format handles this naturally by using vendor-self-disclosure as primary evidence.
• Hugo HU's Mainland engagement is a project-level signal worth documenting. Hong Kong-based vendors are increasingly bridging into Mainland China's enforcement ecosystem. This widens the practical surveillance footprint beyond Hong Kong's licensed-VASP regime. Worth a section in the white paper about Asian surveillance vendor geography if you ever pursue that angle.
• The Bitrace blog is a public-record gold mine. Bitrace publishes regular case studies, investigation reports, training summaries, and product announcements. For Asian vendors where USAspending-equivalent procurement records don't exist, vendor blogs are often the best primary source. The verification record cites blog.bitrace.io directly because it's the most authoritative evidence available.
• The 2025 Crypto Crime Report is a tell. When a surveillance vendor publishes an annual "crypto crime report," it's a strong industry-positioning signal. Compare to Chainalysis's "Crypto Crime Report" (the original industry standard) and TRM Labs' equivalent. Bitrace is positioning as the Asia equivalent of those vendors. Worth tracking if you ever do an industry-survey angle.
