Lore

Stellar blockchain token explorer for MTLAP (Persons) and MTLAC (Companies) tokens. Provides a web interface to browse token holders and view detailed account information including balances, metadata, and trustlines.

Overview

Lore is a specialized explorer for the MTL Association ecosystem on the Stellar network. It tracks:

• MTLAP (Persons) - Individual membership tokens
• MTLAC (Companies) - Company/organization tokens

Key Features

• Browse all MTLAP and MTLAC token holders
• View detailed account information (name, about, websites, trustlines)
• Council voting status and delegation tracking
• Reputation scoring with weighted calculations
• Portfolio valuation in XLM
• Relationship graph visualization
• Dark/light theme with responsive design

Blockchain Social Network

The MTL ecosystem implements a social network layer on Stellar using ManageData operations:

• Identity: Name, About, Websites stored as base64-encoded ManageData
• Relationships: 27 relationship types (Employee, Employer, Partner, Family, etc.) linking accounts
• Delegation: Council voting power delegation chains
• Association Tags: Programs and Factions for categorizing members

Prerequisites

• Go 1.24+
• PostgreSQL 16+
• Docker & Docker Compose (recommended)

Development

Docker Development (Recommended)

Use Docker Compose for local development with fast iteration:

# Quick start: build, start services, sync data
make dev

# After making code changes, rebuild and restart:
make dev-restart

# View logs
make dev-logs

# Stop everything
make dev-down

# Reset database and re-sync
make db-reset && make dev

Important: Docker containers run Linux. The Makefile handles cross-compilation automatically. Never run go build manually before make dev-restart — always use Makefile targets.

Local Development (without Docker for app)

# Start only PostgreSQL
make db

# Build
go build -o lore ./cmd/lore

# Sync data from Stellar
./lore --database-url "postgres://lore:lore@localhost:5432/lore?sslmode=disable" sync

# Start server
./lore --database-url "postgres://lore:lore@localhost:5432/lore?sslmode=disable" serve

Open http://localhost:8080

Commands

# Run tests
go test ./...

# Format and lint
go fmt ./...
go vet ./...

# Generate mocks
mockery

Configuration

Flag	Env Var	Default	Description
--database-url	DATABASE_URL	(required)	PostgreSQL connection URL
--port	PORT	8080	HTTP server port
--horizon-url	HORIZON_URL	https://horizon.stellar.org	Stellar Horizon API URL
--log-level	LOG_LEVEL	info	Log level (debug, info, warn, error)
