CADENA: Civic-Scale Social Blockchain Network

1. Overview

CADENA is a civic-scale social network and public infrastructure protocol focused on three pillars: (1) transparent public budgets, (2) verifiable reputation and identity, and (3) programmable governance via prediction markets and voting systems. The protocol launches first as a set of Solana programs and front-end clients, then evolves into a sovereign layer-one based on a Solana fork when network scale and funding justify a dedicated chain.

CADENA is designed to support the principles of the proposed CADENA Act framework: open ledgers for public spending, accountable digital governance, and citizen-readable state. The goal is not only to store data on-chain, but to make civic flows legible to everyday users through opinionated product design.

2. Architecture

2.1 Layers

• Application Layer: Web and mobile clients powered by Next.js and TypeScript, optimized for mobile-first usage and low-friction onboarding via Solana wallets.
• Protocol Layer (Solana): Rust programs (Anchor-based) providing primitives for identities, profiles, reputation, proposals, treasuries, budgets, prediction markets, and voting.
• Sovereign L1 (CADENA Chain, future): A Solana fork providing a dedicated execution environment, custom fee policies, and a validator set aligned with civic and institutional use cases.

2.2 Data Model

CADENA uses a hybrid on-chain / off-chain data model. High-value, governance, and budget-critical state is stored on-chain (e.g., identities, treasury flows, proposals, votes), while high-volume social data is stored off-chain with on-chain hashes for integrity.

• Identity Accounts: Represent a user's canonical on-chain presence, linking wallet, reputation, and optional off-chain identifiers.
• Profile & Reputation: On-chain scores and badges derived from verifiable activity: proposals, votes, contributions, and prediction market performance.
• Budget & Treasury Accounts: Structured program accounts representing funds under a specific mandate, with constraints on how tokens can be moved and under what governance rules.

3. Core Modules

CADENA exposes the following first-class modules at the protocol layer:

• Identity & Reputation: Wallet-linked accounts with upgradable reputation curves and support for badge-style NFTs.
• Budgets & Treasuries: Programmable, proposal-gated token flows with public reporting views for citizens and auditors.
• Prediction Markets: Market primitives for policy and outcome forecasting, optionally feeding into governance signals.
• Voting: Configurable governance templates ranging from token-based votes to reputation-weighted or hybrid mechanisms.

4. Roadmap

The roadmap follows four stages: (I) Solana social graph & token launch, (II) budgets, DAO tooling, and prediction markets, (III) identity, forums, and experimental voting, and (IV) CADENA Chain as a sovereign L1 with a bridge from Solana.

5. Disclaimers

CADENA is experimental technology. It is not an investment product, and nothing in this document or related interfaces constitutes financial, legal, or political advice. Jurisdictions differ: it is each participant's responsibility to understand their local laws and act accordingly.
