Enhance Multi-sig Transaction Serialization

[grantfox-oss]

Description

Standardize transaction serialization to ensure deterministic proposal hashing.

Problem Statement

Different versions of the client library interpret JSON object ordering differently, leading to inconsistent transaction hashes for the same proposal. This prevents multi-sig signers from reaching consensus, as their calculated hashes never match.

Technical Requirements

• Requirement: Implement a canonical JSON serializer that sorts keys alphabetically.
• Requirement: Ensure that numbers and addresses are cast to standard types before serialization.

Implementation Guide

• Suggested Approach: Use a custom serializer module in src/engine/serialization.rs that enforces alphabetical key sorting using serde.
• Branch Strategy: git checkout -b fix/deterministic-hashes
• Affected Areas: src/engine/serialization.rs

Acceptance Criteria

• Multiple test runs from different environments produce identical hashes for the same input.
• Integration tests verify hash consistency across different serde versions.

Definition of Done

• Code reviewed
• CI/CD passed

Hello, I understand that you have different versions of the client library that interpret JSON object ordering differently which leads to inconsistent transaction hashes for the same proposal & at the same time it stops multi-sig signers from reaching consensus. I will standardize transaction serialization to ensure deterministic proposal hashing by using a custom serializer module in src/engine/serialization.rs that enforces alphabetical key sorting using serde. Once complete, i'll make sure it meets the acceptance criteria by running tests that help with producing identical hash output.
