# Participatory assessment and verification in TIM

> Producers, partners and buyers agree on fair criteria, gather plot or area evidence, then assess and vote on acceptance under shared conditions. Assessment data and results from each round are recorded on Blockchain as a history that cannot be rewritten and can be reviewed together.

## How do participants agree and verify together?

1. **Agree on fair criteria**

   Producers and others involved agree on criteria, roles and acceptance conditions that fit the local context.

2. **Gather evidence from each plot or area**

   Connect activities, photos and assessment data to a plot or area, giving everyone the same evidence to review.

3. **Assess and vote together**

   Review evidence, discuss findings and vote within agreed roles, accepting results under shared conditions.

4. **Record each round on Blockchain**

   Store assessment data and results as a history that cannot be rewritten, so everyone can revisit and verify each round.

## How does this relate to PGS?

Participatory Guarantee Systems (PGS) involve local stakeholders in assurance, drawing on trust, social networks and knowledge exchange.

Like PGS, the people involved shape the criteria and assess together. TIM adds digital evidence, voting and Blockchain records so each round can be reviewed.

## What does Blockchain help people verify?

Store assessment data and results as a history that cannot be rewritten, so everyone can revisit and verify each round.

Blockchain preserves the assessment data and results of each round. Whether the evidence meets the agreed conditions is decided by participants through assessment and voting.

## Can I record activities beyond the field?

Yes. Record forest care, women’s roles, shared income, local knowledge, craft and household finances. Activities can be on or off the plot, or at home, with details and photos.
