MODULAR / ONE EVIDENCE CORE
Built around your desk.
Configured for your market.
Four working local comparison modules, with shared exception handling, evidence exports and configurable source schemas. Institution profiles select a starting module; you can change it.
Trading venues
Compare trade extracts, clearing records and member books. Review executions, missing records and duplicates.
Trades & executions ↓Banks & payments
Reconcile internal cash entries against statement extracts, including debit/credit direction, value date, amount and posting status.
Cash & ledger entries ↓Brokers & DTVMs
Compare execution and allocation extracts. Extend to cash and custody snapshots through the same module selector.
Trades + cash + positions ↓Asset managers & funds
Compare portfolio snapshots with administrator or custodian files, including quantities, prices and reported market values.
Positions & custody ↓Custodians & administrators
Match instrument positions and cash records at an agreed cutoff. Preserve source values for independent review.
Positions + cash ↓Other market participants
Reuse the module registry, map source headers and export a versioned configuration for your own integration.

A common core.
Local data contracts.
Country presets configure file conventions and identify regulatory review areas. They do not activate connections or determine legal compliance.
Compose the operating model.
Choose institution, module, date and decimal conventions, delimiter and column mapping. Record jurisdiction, purpose, processing region and retention-policy references in a portable JSON configuration.
- Versioned module and evidence schemas
- Explicit GDPR scope declaration
- Extensible adapters and policy references
Local formats. Explicit boundaries.
Brazil presets support DD/MM/YYYY, decimal commas and semicolon CSVs. Use private local references for Pix, STR, B3, bank statements and portfolio systems after mapping your authorized extracts.
- LGPD + ANPD · BCB/CMN · CVM review
- Mexico, Colombia, Chile and Argentina profiles
- Custom profile for other LatAm jurisdictions
No live B3, Pix, STR, Open Finance, SPEI or supervisory reporting connection is enabled. Calendars, market cutoffs, chart-of-accounts mappings and regulatory filings are institution-specific adapters.
LOCAL / MODULAR RECONCILIATION WORKBENCH
Your files.
Your environment.
Compare trade, cash, position or Bloch receipt extracts without uploading them. Processing and report generation happen in this browser; files remain in memory until you clear or close the page.
Download the offline workbench ↓Configure your module
GLOBAL + LATAMCustom source mapping + policy references
Map a canonical field to its source column, for example {"account":"conta"}. Unmapped names remain canonical. Both files use the same mapping and format. Normalize differing systems before comparison.
These references are stored in the private evidence manifest. They do not enforce retention, authenticate permissions, verify residency or certify compliance. Institutional controls must implement those policies.
Applying a configuration, loading files or rerunning clears the current report and review journal. Download them first. Examples reload using the selected module.
TRADE COMPARISON / V1
SYNTHETIC EXAMPLEMatching rules, CSV schema and limits
Required columns (order may vary):
record_id,trade_date,settlement_date,venue,member,account,instrument,side,quantity,price,currency,net_amountThe key is trade_date + venue + member + record_id. All remaining fields must match. Outer whitespace is trimmed; enum fields and currency are uppercased. Identifiers remain case-sensitive. Decimal amounts are compared exactly, with up to 8 fractional digits and zero tolerance. Dates use the selected format and normalize to YYYY-MM-DD. Duplicate keys always require review.
Two-file comparison within the selected module. Source authenticity and completeness are not verified. Use consistent cutoffs and exports. Output includes private source values; retain it in your approved environment.

Investigation overview
Where fields disagree
Keys with differing values, by field. One key can appear in several bars. Missing records and duplicates are separate outcomes.
Review progress
Latest annotation per exception. Explained records retain their original discrepancy. Reviewer labels are self-declared.
Full-report counts. Selecting a bar replaces the queue filters with that selection. Bars show record counts, not financial exposure or risk scores.
Exception review journal
LOCAL ANNOTATIONS / UNSIGNEDSelect Review exception in the records table to document a discrepancy. Entries retain the original outcome and bind to this exact report. Names and timestamps are self-declared; an explanation is not an approval or a corrected match.

Keep evidence, original CSVs and review JSON together in approved local storage. To resume a previous report, use Verify below, then open it for review. Up to 1,000 journal entries.

Investigation queue
LOCAL SEARCH + FILTERSSearch ignores letter case and accents; every space-separated term must occur in a key, normalized source value or latest review label/note. Filters combine. Search never changes matching rules. Follow-up first orders: follow-up required, reopened, not reviewed, investigating, explained, then matched. Latest journal entry uses sequence, not a trusted timestamp.
All selected keys across every page. Includes private review notes and both evidence/journal digests; retain the full JSON files separately.
| Record / key | Outcome | Source rows A / B | Comparison detail |

INDEPENDENT RECOMPUTATION / LOCAL FILES
Reopen the evidence.
Check every outcome.
Start with the exported evidence JSON and both original CSVs. Recompute file digests, matching rules, records and outcomes locally. An optional retained SHA-256 checks the report against a separately stored reference.
Retain the digest separately before verification. A consistent replacement of all files cannot be detected without a trusted external reference. Review journals are unsigned and have no protected history or rollback detection. Preserve original JSON formatting.
Local consistency checks passed
RECOMPUTED / NOT CERTIFIEDExact report SHA-256
Opening this report replaces the current comparison and review session above. Download any unsaved work first. This check does not authenticate the source, reviewer, timestamp or on-chain status.
03 / OFF-CHAIN + ON-CHAIN
Keep the records private.
Make the evidence verifiable.
The local Bloch receipt module compares imported on-chain observations with internal records. The Bloch Protocol is also the proposed shared evidence layer. Your institution retains the detailed books, audit material and control of what may be released.
The complete audit trail
- Source records, account references and business context
- Exact comparison rules and reproducible results
- Reviewer decisions, access and retention policies
- Private opening material for a reviewed commitment
The browser workbench performs local comparison. Authenticated feeds, approvals, encrypted retention and organizational controls belong in the institutional deployment.
A minimal evidence reference
- Publish only an approved, reviewed hiding commitment
- Sign through an institution-controlled signer
- Retain the exact transaction and block reference
- Verify inclusion, canonicality and finality separately
This site does not sign or broadcast transactions. The local report hash is not a qualified hiding commitment. No private records, account IDs or source-file digests belong in the public payload.
AVAILABLE BLOCH NETWORK RESOURCES
Inspect the chain behind the evidence.
Use the public explorer and operator references when designing the receipt verification and network adapter.
04 / AUDITABLE BY DESIGN
Re-run the comparison.
Follow the evidence.
Give an independent reviewer the source extracts, rule version and exact report. Compare the results again before drawing conclusions.
Source → result
Retain both file digests, source row references, normalized values and field-level differences. Duplicate keys never disappear into a match.
Result → review
Keep decisions and reviewer signatures in your controlled case system. A browser-generated report is unsigned and its creation time comes from the local clock.
Review → chain
For a qualified integration, verify the approved commitment opening against the exact chain payload and an independently assessed receipt. A txid alone is insufficient.
GOVERNANCE / PRIVACY + REGULATORY SCOPE
Controls you can inspect.
Obligations you can map.
Start with the institution's actual activities, licenses, countries and data flows. The catalog below links official sources and identifies implementation areas; it is a starting register, not a compliance certificate or exhaustive legal determination.
Implemented in this workbench
- Local processing; no file-upload endpoint, analytics, third-party scripts or remote font requests.
- Network connections blocked by the content security policy. Source records are held in page memory without application persistence.
- Strict module fields, bounded files, explicit duplicate handling and exact values. Reports record the applied configuration.
- No signer, publication endpoint or transaction broadcast. Private records and local report digests are never automatically placed on-chain.
Required in an institutional deployment
- Identity and role-based access; separation of preparation, review and approval; authenticated source adapters.
- Approved processing purpose and lawful basis; field minimization, rights requests, retention, legal holds and controlled deletion.
- Encryption and key custody, residency and transfer review, monitoring, incident response, continuity and recovery.
- Reviewed commitment privacy, institution-held signing, exact payload binding, source independence and chain-evidence verification.
Brazil / LGPD, ANPD, Bacen–CMN and CVM
Privacy: map purpose, data-subject rights, retention, security and international transfers against the LGPD. Review ANPD rules on incident communication and international transfers.
Bacen / CMN: identify the institution's applicable cybersecurity, outsourced-processing and internal-control rules. CMN 4.893 and BCB 85 have distinct scopes; review the consolidated text and amendments, including the rules affecting brokers and DTVMs.
CVM: map intermediary records and controls, portfolio-management procedures, fund-specific obligations and PLD/FTP scope. Reconciliation exports can support a review workflow; the workbench does not submit regulatory reports or perform the institution's AML program.

Also assess bank secrecy, accounting and reporting, record retention, market infrastructure and self-regulatory requirements applicable to the institution. These require additional local mapping.
Global / GDPR, financial-sector resilience and custom jurisdictions
Where GDPR applies, map processing principles, lawful basis, rights, privacy by design, security and international transfers. EU financial entities must separately assess whether DORA's operational-resilience and ICT requirements apply. Other jurisdictions need their own privacy, securities, banking, recordkeeping and reporting register.
LatAm / Mexico, Colombia, Chile and Argentina
Mexico: review the current LFPDPPP, plus the institution's CNBV and Banxico obligations. Colombia: determine the applicable scope of general personal-data rules and financial-data rules; add SIC and financial-supervision requirements. Chile: review current Law 19.628 and CMF obligations, with a transition review for Law 21.719. Argentina: map Law 25.326 and the institution's AAIP, BCRA and CNV requirements.
