PLENA Informal Credit & Savings Groups
Receipts for contributions, payouts, and loans in the savings groups that move trillions globally without formal banking. For tontines, chamas, susu, stokvels, arisans, hui, and the seven hundred million people worldwide who participate in rotating savings and credit associations whose entire transactional record is currently a handwritten ledger and group memory.
Opening problem
Roughly seven hundred million people worldwide are estimated to participate in informal rotating savings and credit associations. The practices go by many names across communities: tontines, chamas, stokvels, susu, arisan, hui, cundinas, paluwagan, kameti, ekub, esusu, adashi, gam'eya, and others. Each operates as a member-funded mutual-credit and mutual-savings vehicle. Members contribute regularly. Payouts rotate. Loans are made and repaid. Defaults are handled within the group's social fabric.
The aggregate financial flows are substantial. Estimates place the global volume of informal rotating savings and credit at over one trillion US dollars annually across the regions where the practice is most prevalent. Diaspora populations often continue participating in groups across borders, with members in multiple countries contributing to a single group hosted in the country of origin.
The transactional record of these groups currently exists, almost universally, as handwritten ledgers maintained by a designated record-keeper, supplemented by the collective memory of the membership. The ledger is vulnerable to fire, flood, theft, and the death or relocation of the record-keeper. The collective memory is vulnerable to the same dispute patterns affecting any community-level transaction: members deny contributions they made, dispute payouts they received, disagree about loan terms, contest membership rolls. Disputes are common as groups scale, as members migrate, or as economic stress increases.
PLENA Informal Credit & Savings Groups is built to provide the receipt layer for these transactions: a per-meeting video attestation of contributions made, payouts disbursed, loans authorized, and votes taken; a structured per-member receipt of cumulative position; a sealed handover packet that allows successor record-keepers to take over without loss of history. It is documentation infrastructure for the informal finance sector at the scale at which it actually operates.
Five workflows PlenaProof covers
Each workflow produces four artifacts: a sealed declaration, the underlying meeting evidence, a cumulative yearbook, and a multilingual handover packet.
Group Formation and Membership Attestation
At group formation, witnessed declaration of the membership, the rotation schedule, the contribution amount, the rules for loans, the consequences of default, the designated officers. Captured by video at the formation meeting with all founding members present.
- Formation Declaration. Sealed statement of the founding rules and members.
- Sealed Rules Document. The full group constitution, hashed.
- Membership Roll. Each founding member identified, on camera, with their contribution commitment.
- Multilingual Handover Packet.
Per-Meeting Contribution and Payout Attestation
At each regular meeting (weekly, biweekly, monthly depending on group), video documentation of contributions paid in (each member identified, amount stated, contribution acknowledged) and payouts disbursed (the rotating recipient identified, amount handed over, member acknowledgment). The transactional core of the group, captured per meeting.
- Meeting Declaration.
- Sealed Meeting Evidence. Full meeting video and ledger photos.
- Cumulative Meeting Yearbook. Per-member rolling balance across meetings.
- Multilingual Handover Packet.
Loan Origination, Performance, and Default Receipts
When loans are made from group funds, witnessed receipts of loan terms (amount, interest if any, repayment schedule, guarantors), periodic performance attestation, and default handling per group rules. Critical because loan disputes are the most common source of group dissolution.
- Loan Declaration. Terms stated on camera with borrower, lender (the group), guarantors.
- Sealed Loan Evidence.
- Performance Yearbook. Repayment progression or default events.
- Multilingual Handover Packet.
Officer Succession and Record-Keeper Handover
When the designated record-keeper or treasurer changes — whether scheduled rotation, resignation, death, or migration — structured handover of the cumulative group records, with witnessed transfer of authority. Critical for groups whose continuity depends on the record-keeper, who often holds informal authority beyond their formal role.
- Handover Declaration.
- Cumulative Records Hash. The full PLENA-anchored history transferred.
- Successor Authority Receipt. The new officer's authority acknowledged on camera by the membership.
- Multilingual Handover Packet.
Dispute Resolution and Group Dissolution Continuity
When disputes arise or groups dissolve, structured documentation of the dispute, the resolution attempted (per group rules or by community elders), the outcome, and any continuing obligations. For groups that dissolve cleanly, final accounting and member sign-off. For groups that fracture, documentation of the fracture and the positions of dissenting members.
- Dispute Declaration.
- Sealed Dispute Evidence.
- Resolution or Dissolution Documentation.
- Multilingual Handover Packet.

Same complement-not-replace disclaimer. PlenaProof does not hold group funds, adjudicate disputes, enforce contributions, or provide banking services. It produces the receipt layer that the group's own designated officers and the supporting NGO ecosystem can act on.
The 100-Year Operating Commitment
Informal savings groups often outlast individual members; founding members' contributions and roles need to remain readable to subsequent generations.
Informal savings groups often outlast individual members; founding members' contributions and roles need to remain readable to subsequent generations. Every artifact replicated, anchored, verifiable across generational continuity.
Why this differs from existing microfinance platforms
CARE VSLA, Catholic Relief Services SILC, and similar NGO-supported savings-group programs provide group-formation training and supporting infrastructure but operate top-down — the NGO supports formation of new groups under its program. PLENA Informal Credit & Savings Groups operates bottom-up — any existing group can adopt PLENA receipts without participating in any NGO program, and the group retains full control of its records.
Group-controlled
No NGO or institution holds the records.
Compatible with existing groups
Does not require new group formation under a specific program.
Multi-language, multi-country
Supports the diaspora-participation pattern across borders.
Cryptographic anchoring
Survives the loss of the local NGO supporter or the program's funding.
Pay-per-use
$3 per meeting attestation, sustainable at group volume — same architecture as Agreements & Contracts.
Existing instruments this complements
- CARE Village Savings and Loan Association methodology
- Catholic Relief Services Savings and Internal Lending Communities (SILC)

What this does not do
PLENA Informal Credit & Savings Groups does not hold group funds (funds remain with the group's designated treasurer). It does not adjudicate disputes (groups handle disputes per their own rules). It does not enforce contributions or loan repayment. It does not provide microfinance loans or banking services. It does not constitute formal banking regulation or registration. It documents.
