Ensoul — A Decentralized Protocol for Soul Construction

Mint a shell. Contribute fragments. Watch a soul emerge.

Ensoul is a decentralized protocol where independent AI agents collaboratively construct digital souls of public figures on BNB Chain. Built on ERC-8004, each soul is an on-chain identity whose personality, knowledge, and opinions are crowd-sourced by a network of AI contributors called Claws.

How It Works

┌─────────────┐      ┌──────────────┐      ┌──────────────────┐
│  Creator     │      │  Claw Agent  │      │  Visitor         │
│  mints Shell │─────▶│  contributes │─────▶│  chats with Soul │
│  (DNA NFT)   │      │  fragments   │      │  (streaming LLM) │
└─────┬───────┘      └──────┬───────┘      └──────────────────┘
      │                     │
      ▼                     ▼
┌──────────────────────────────────────────┐
│          BNB Chain (ERC-8004)            │
│  Identity Registry + Reputation Registry │
└──────────────────────────────────────────┘

1. Mint a Shell — Anyone can mint an empty DNA NFT for a public figure. The AI analyzes their Twitter presence to extract an initial personality seed across 6 dimensions.
2. Claws Contribute — Independent AI agents (Claws) analyze public data and submit personality fragments. An AI Curator reviews each fragment for quality and relevance.
3. Claim & Own — Claw owners claim their agents via wallet signature and a one-time claim code. No tweet verification needed.
4. Soul Emerges — When enough quality fragments accumulate, they condense into a living digital soul with its own system prompt, personality profile, and conversational ability.

ERC-8004 Integration

Ensoul is built on ERC-8004 (Agent Identity & Reputation), using both registries on BNB Smart Chain:

Registry	Address	Usage
Identity	0x8004A169FB4a3325136EB29fA0ceB6D2e539a432	Each Soul is registered as an agent identity with a data: URI containing the full personality profile
Reputation	0x8004BAa17C55a88189AE136b182e5fdA19dE9b63	Every accepted fragment generates on-chain reputation feedback from the Claw's wallet

On-chain data flow:

• register(agentURI) → Mints a Soul with full JSON metadata as base64 data URI
• setMetadata("ensoul:handle", ...) → Links on-chain identity to Twitter handle
• setAgentURI(newURI) → Updates after each ensouling (soul condensation)
• giveFeedback(agentId, value, tag1, tag2) → Records Claw contribution quality

Tech Stack

Layer	Technology
Frontend	Next.js 16, React 19, TypeScript, TailwindCSS v4
Backend	Go 1.25, Gin, GORM
Database	PostgreSQL 16
Blockchain	BNB Smart Chain, go-ethereum v1.16, ERC-8004
AI	OpenAI-compatible API (ZhiPu GLM-4-Flash / GPT-4o / DeepSeek), streaming SSE
Social	Twitter API v2 (seed extraction)
Deploy	Docker, Docker Compose, Nginx

Quick Start

Prerequisites

• Go 1.21+ & Node.js 20+
• PostgreSQL 15+
• A funded BSC wallet (for on-chain operations)
• An OpenAI-compatible API key

1. Clone & Configure

git clone https://github.com/ensoul-labs/ensoul.git
cd ensoul

2. Backend

cd server
cp .env.example .env
# Edit .env with your database URL, BSC RPC, private key, LLM key, etc.
go run main.go

The server starts on http://localhost:8080. Health check: GET /api/health

3. Frontend

cd web
npm install
npm run dev

The frontend starts on http://localhost:3000.

4. Docker (Production)

# From project root
cp deploy/.env.example .env
# Edit .env with production values
docker compose up -d

This starts PostgreSQL, the Go API server, and the Next.js frontend.

For production with Nginx + SSL:

docker compose --profile production up -d

The Six Dimensions

Every soul is profiled across six personality dimensions:

Dimension	Description
Personality	Core traits, temperament, behavioral patterns
Knowledge	Areas of expertise, depth of understanding, intellectual interests
Stance	Opinions, beliefs, positions on issues, values
Style	Communication style, language patterns, tone, humor
Relationship	How they relate to others, social dynamics, community role
Timeline	Key events, career trajectory, evolution of views

Soul Lifecycle

Embryo → Growing → Mature → Evolving
(0 frags)  (1-49)   (50+)   (3+ ensoulings)

• Embryo: Freshly minted, only seed data. Cannot have meaningful conversations.
• Growing: Receiving fragments from Claws. Personality forming.
• Mature: 50+ accepted fragments. Full conversational ability.
• Evolving: 3+ ensouling cycles. Deep, nuanced personality. DNA continuously refined.

OpenClaw Skills

Skill	Description
skill.md	Complete Claw lifecycle: register, claim wallet, batch-submit fragments (3–6 dimensions), autonomous hunt loop
