Version: Draft 1.2
Date: June 2026

Executive Summary#

Continuum began as a local-first platform for managing sovereign identities, signing events, publishing content, and preserving user ownership through open protocols such as Nostr.

As the platform has evolved, a broader opportunity has emerged.

Individuals now maintain dozens—or even hundreds—of digital identities across banks, brokerages, healthcare providers, employers, government agencies, cloud applications, cryptocurrency platforms, developer services, and decentralized protocols.

Each identity exists in isolation, often requiring separate credentials, profile information, recovery procedures, notes, documents, and authentication methods.

Continuum Vault extends the Continuum Core platform by providing a unified, encrypted, local-first identity workspace where every digital relationship can be managed from a single location under the user's control.

Continuum is built on a simple premise: identity should belong to the user rather than the applications they use. Everything else in this document follows from that principle.

Rather than treating passwords as the product, Continuum treats digital identities as first-class objects.

Background#

The modern Internet has become increasingly fragmented.

A typical user maintains accounts for:

Each service introduces its own authentication mechanism, profile information, account history, recovery process, and supporting documentation.

Users frequently rely upon multiple disconnected tools including:

While each tool addresses part of the problem, none manages the complete relationship between a user and every digital service they use.

Problem Statement#

Traditional password managers focus primarily on one responsibility:

Remember my credentials.

Credentials, however, represent only one component of an online identity.

Every account often includes:

Managing this information across multiple applications creates unnecessary complexity and increases the likelihood of forgotten information, duplicated effort, and security mistakes.

Vision#

Continuum Vault provides a local-first identity workspace where every online account becomes an Identity Record.

An Identity Record represents the complete relationship between a user and a digital service.

Instead of organizing passwords, Continuum organizes identities.

Objectives#

The Continuum Vault project will:

Scope#

1. Identity Records#

Every online service becomes an Identity Record containing information such as:

Identity Records become first-class objects within Continuum.

2. Identity Workspace#

Each Identity Record may additionally contain:

The objective is to centralize everything associated with a digital relationship rather than storing information across multiple applications.

3. Browser Integration#

Continuum already includes an open-source Continuum Browser Signer that securely communicates with the local Continuum workspace for Nostr authentication.

Continuum Vault introduces a complementary Continuum Vault Extension focused on legacy website authentication and autofill.

While both extensions share common architectural principles, they serve different purposes and are intentionally designed as separate components. Separating these responsibilities reduces the permission scope of each extension while allowing both to evolve independently.

Typical workflow:

  1. User selects an Identity Record within Continuum.
  2. Continuum launches the associated login page.
  3. The browser extension securely communicates with the local Continuum workspace.
  4. The appropriate credentials are retrieved.
  5. Login fields are automatically populated.

The browser extension is not intended to become a standalone password manager.

Continuum remains the authoritative source for identity information.

4. Local-First Security#

All sensitive information remains encrypted within the local Continuum workspace.

Credentials are decrypted only when required during authorized authentication workflows.

No cloud synchronization is required.

No third-party password storage is required.

Users retain complete ownership of their identity data.

Authentication Evolution#

Legacy username/password authentication represents only one authentication method supported by Continuum.

The architecture is designed to evolve alongside future authentication technologies.

Supported authentication methods may include:

The authentication mechanism becomes an implementation detail.

The Identity Record remains constant.

Relationship to Continuum Core#

Continuum Vault is not intended to become a separate product.

It is a core capability of the Continuum platform.

The Vault complements existing Continuum functionality rather than replacing it.

Relationship to Nostr#

Nostr remains a first-class identity provider within Continuum.

However, Continuum extends beyond any individual protocol.

Within Continuum, a Nostr identity becomes one type of Identity Record alongside traditional SaaS applications, financial institutions, healthcare providers, developer platforms, and future authentication systems.

This positions Continuum as a general-purpose identity platform rather than a protocol-specific client.

Existing Foundation#

Continuum Vault builds upon capabilities that already exist within Continuum today.

Current functionality includes:

Continuum Vault extends these existing foundations rather than introducing an entirely new architecture.

The existing open-source Continuum Browser Signer already demonstrates secure browser-to-workspace communication for Nostr authentication. The Continuum Vault Extension builds upon many of the same architectural principles while remaining a separate component with its own security model and permission scope.

Long-Term Vision#

Continuum seeks to become the user's trusted identity workspace.

Rather than maintaining separate applications for passwords, browser extensions, notes, decentralized identities, authentication, and future identity technologies, users manage every digital relationship from a single encrypted workspace under their own control.

The browser becomes an interface.

Applications become interchangeable interfaces rather than permanent homes for identity.

Identity remains with the user.

As new authentication technologies emerge, users should not be forced to migrate between identity managers. Instead, Continuum should evolve to support new authentication methods while preserving a consistent user experience centered around Identity Records.

Design Principles#

The Continuum Vault project is guided by the following principles.

Local First#

Identity data belongs to the user, not a cloud service.

Encrypted by Default#

Sensitive information remains encrypted at rest and is only decrypted during authorized authentication workflows.

Identity-Centric#

Continuum organizes relationships rather than simply storing credentials.

Protocol Agnostic#

Legacy SaaS applications, financial institutions, decentralized protocols, and future authentication systems are all treated as supported identity providers.

User Controlled#

Authentication occurs only under explicit user control.

The browser extension acts as a bridge between websites and the local Continuum workspace rather than functioning as an independent credential store.

Extensible#

The platform should support future authentication mechanisms without requiring fundamental architectural changes.

Open Foundation#

Continuum is designed around open standards and open protocols to maximize interoperability and user ownership.

The version of Continuum described in this document is not yet fully open source. My intention is to release Continuum as open source once the project reaches the milestone described on the Continuum website.

Until then, development continues in a private repository while the platform matures.

Benefits#

Continuum Vault provides users with:

Conclusion#

Continuum Vault represents a natural evolution of the Continuum platform.

By combining identity management, browser integration, authentication, documentation, historical context, and local-first security into a unified workspace, Continuum moves beyond password management toward comprehensive digital identity management.

Legacy username/password authentication is simply the first step.

The long-term objective is to provide a single platform capable of managing identities across both today's Internet and the decentralized systems of tomorrow.

Rather than asking users to manage passwords, passkeys, Nostr identities, Bitcoin wallets, browser extensions, and future authentication technologies independently, Continuum seeks to provide a unified identity workspace where every digital relationship remains under the user's ownership and control.

Identity should belong to the user—not the application.

Continuum is a local-first identity workspace, and Nostr is one of the identity systems it supports.
