# Sophon v1 (Legacy)

> The original Sophon Chain thesis

<Warning>
  This page describes **Sophon v1**, the legacy chain thesis. Sophon is winding down
  the chain and focusing on applications built on Base. See the
  [Sophon Chain migration guide](/migration) for current actions and dates.
</Warning>

## The original chain thesis

Sophon v1 launched as a general-purpose blockchain built with the ZK Stack and
positioned toward entertainment and consumer applications. It aimed to make crypto
useful inside those applications without requiring users to understand wallets,
seed phrases, gas, or blockchain infrastructure.

The legacy Sophon OS combined Sophon Home, Sophon Account, Sophon+, a Social Oracle,
and the ZK Stack-powered chain into a consumer-facing system. Its central thesis was
that crypto adoption improves when the technical layer disappears and the benefits
become clear to the user.

## Data as a consumer primitive

The v1 data thesis centered on protocol-level zkTLS: users could verify selected
parts of their Web2 activity without exposing the underlying sensitive data.
Applications could then use verified reputation, achievements, spending, creator
audiences, and other social signals as inputs.

The intended application areas included gaming, social products, betting,
ticketing, AI, and other entertainment experiences.
