Mod validation multisign

Add guardians sequence

Verifiy multisign sequence

Overview

ModValidationMultisign is a versatile validation module within the Veive protocol, designed to handle multi-signature validation scenarios. This module can be applied in various contexts, such as wallet multi-ownership and account recovery, by utilizing a set of designated signatories known as "guardians." Its flexibility allows the module to support different use cases depending on the scope in which it is installed. The module is agnostic to the signature method, meaning guardians can use different signing methods without affecting the module's functionality.

Purpose

The primary function of ModValidationMultisign is to validate operations by requiring multiple signatures from designated guardians. This feature is crucial for scenarios such as:

1. Account Multi-ownership: In this context, the module ensures that all owners (guardians) must approve transactions. By installing the module in the entry_point=allow scope, every operation requires pre-authorization from all guardians, providing a robust layer of security.

2. Account Recovery: The module can also be used to recover access to an account. If the primary owner loses access, the guardians can authorize the installation or removal of modules (such as replacing a lost device's public key in a WebAuthn module). This is achieved by configuring the module to validate operations in the install_module and uninstall_module scopes.

Guardian Management and Thresholds

• Guardians: Guardians are designated signatories who can validate operations. The module includes functions to add or remove guardians, making it adaptable to changing security needs.

• Threshold: A key feature is the ability to set a threshold, determining how many guardian signatures are required to validate an operation. This threshold can be configured for different security levels, allowing for scenarios where, for example, only a subset of guardians is needed to authorize an action.
