# Blockchain Transparency

Every prediction and settlement action is recorded permanently on the blockchain. This creates an immutable audit trail that anyone can verify.

## What Is Recorded On-Chain

| Record Type            | What It Proves                                          |
| ---------------------- | ------------------------------------------------------- |
| Prediction submissions | The exact price forecast, who made it, and when         |
| Settlement results     | The oracle price, Merkle root, and total amounts        |
| Validator signatures   | Which independent validators approved the settlement    |
| Reward claims          | The exact amount delivered to each rewarded participant |
| Refund transactions    | Full entry fee returned for cancelled markets           |

## Multi-Chain Operations

Uniocean operates across multiple blockchain networks. Markets may run on different chains, but the same transparency guarantees apply everywhere:

* All predictions produce permanent transaction hashes
* All settlements store Merkle roots on-chain
* All validator signatures are recorded

## Immutability

Once a prediction is submitted:

* No one can alter it
* No one can delete it
* No one can reverse it
* The timestamp is fixed by the block it was included in

This means prediction data cannot be manipulated after the fact — not by users, not by the platform.

## Meta-Transactions and Transparency

Although users submit predictions through gasless meta-transactions (the platform relays on their behalf), the on-chain record still shows:

* The user's wallet address as the predictor
* The exact prediction value
* The block and timestamp of inclusion

The relay mechanism does not reduce transparency — it only removes the gas fee burden from users.

## Public Explorers

Users can verify all records using public blockchain explorers. Each transaction hash links to a permanent, publicly viewable record of the action taken.

## Smart Contract Events

The platform's smart contracts emit events for every significant action. These events are indexed and can be queried by anyone, providing a complete history of:

* Market creation (asset, timing, entry fee)
* Every prediction submitted
* Settlement execution (oracle price, Merkle root, fee amounts)
* Reward distributions
