irl.coop Architecture

The Problem: Centralized Collaboration Sucks

If you've ever tried to run a community organization, a cooperative, or even a small business, you know the drill. You start with a mission—maybe it's a neighborhood bakery co-op in Winthrop, MA, or a ceramics collective sharing studio space. Within weeks, you're drowning in subscriptions:

  • Slack for chat ($8/user/month)
  • Notion for docs ($10/user/month)
  • Asana for tasks ($10/user/month)
  • Shopify for sales (2.9% + 30¢ per transaction)
  • QuickBooks for accounting ($30/month)
  • Google Workspace for email ($6/user/month)

This is the SaaS Trap. Your data is siloed across walled gardens. Your organization's identity is fragmented across ten different logins. Platform fees eat 15-20% of your revenue. And at any moment, a vendor can raise prices, change terms, or shut you down entirely.

But here's the deeper problem: these tools weren't built for circles.

A "circle" is how humans naturally organize: the BakeryCoop has 12 members who share ovens and sell bread at the farmer's market. The CeramicsTeam has 8 potters who share kilns and studio space. These circles overlap—Sarah is in both, managing the BakeryCoop's Instagram and teaching pottery classes.

Current tools force you to pick: is Sarah a "BakeryCoop user" or a "CeramicsTeam user"? Can she access both workspaces? Who pays for her seat? What happens when she wants to facilitate a trade between the two circles—pottery mugs for fresh bread?

The fundamental requirement: People belong to multiple circles. Circles need to transact with each other. And all of this must work on mobile devices that people already own, not expensive cloud infrastructure.

This is why we built irl.coop.

Architecture Overview: Six Layers of Decentralization

irl.coop is not a single app. It's a distributed operating system for human cooperation, built from six layers that work together to create a truly decentralized platform.

    CitusCoord --> Phone1
    CitusCoord --> Phone2
    CitusCoord --> PhoneN
    
    Redis --> RedisModule
    Temporal --> Redis

The key insight: Your Android phone isn't just a client—it's a worker node in the distributed database. When you join the BakeryCoop circle, your phone downloads a SQLite shard containing that circle's data. You can read, write, and sync even when offline. The phone also runs Temporal workers, executing workflows on behalf of the circle.

This architecture enables:

  1. True data ownership: Each circle's data lives on member devices, not corporate servers
  2. Zero infrastructure cost: Oracle Free Tier + home servers + member phones = $0/month
  3. Offline-first: Work continues even without internet connectivity
  4. Censorship resistance: No central point of failure or control
  5. Infinite scale: Each new member adds compute and storage capacity

Let's dive into each layer.

Core Architecture Deep Dive

Diagram 1: Citus Multi-Site Sharding with Row-Level Security

The database layer is where irl.coop's magic happens. We use Citus, a distributed PostgreSQL extension that shards tables across multiple worker nodes. But unlike traditional Citus deployments (which run in data centers), our workers are everywhere: a home server in your basement, two Oracle Free Tier VMs, and dozens of Android phones.

    participant Mobile as Mobile App
    participant Redis as Redis + RLS Module
    participant Coord as Citus Coordinator
    participant HomeW as Home Worker
    participant OracleW as Oracle Worker
    participant PhoneW as Phone Worker (SQLite)
    
    User->>Mobile: Authenticate with Lit PKP
    Mobile->>Redis: irl.coop.RLS.CONTEXT SET user_id circle_id
    Redis-->>Mobile: Session token
    
    Mobile->>Coord: SELECT * FROM posts WHERE circle_id = 'BakeryCoop'
    Coord->>Redis: GET RLS context for session
    Redis-->>Coord: {user_id: 'sarah', circle_id: 'BakeryCoop'}
    
    Note over Coord: Apply RLS policy:<br/>WHERE circle_id = current_setting('app.circle_id')<br/>AND user_id IN (SELECT user_id FROM circle_members)
    
    Coord->>PhoneW: Query shard for circle_id='BakeryCoop'
    PhoneW-->>Coord: Return rows (SQLite local cache)
    Coord-->>Mobile: Results
    
    Mobile->>Coord: INSERT INTO posts (circle_id, content)
    Coord->>PhoneW: Write to local shard
    Coord->>OracleW: Replicate to Oracle backup
    Coord->>HomeW: Replicate to home server
    
    Note over PhoneW,HomeW: Async replication via<br/>Citus logical replication

Key architectural decisions:

  1. Sharding by circle_id: Each circle's data lives on specific worker nodes. The BakeryCoop shard might be on Phone#1, while CeramicsTeam is on Phone#2.

  2. Row-Level Security (RLS): PostgreSQL RLS policies enforce that users can only access circles they're members of. The custom Redis module stores session context (user_id, circle_id) and injects it into every query.

  3. Mobile workers use SQLite: Phones can't run full PostgreSQL, so we use SQLite as a local cache. A background sync service (written in Kotlin) pulls changes from the coordinator and pushes local writes.

  4. Triple replication: Every write goes to (1) the primary phone worker, (2) an Oracle Free Tier backup, and (3) the home server. This ensures data survives even if a phone is offline for weeks.

Diagram 2: Temporal Workflow Orchestration

irl.coop uses Temporal.io for all complex, multi-step operations. Temporal provides durable execution—workflows can run for days, survive server restarts, and automatically retry failed steps.

Here's the workflow for publishing content from Webstudio (a visual website builder) to a circle:

graph TD
    Start[User clicks 'Publish' in Webstudio] --> Temporal[Temporal Workflow: publishCircleWorkflow]
    
    Temporal --> Step1[Activity: extractWebstudioContent]
    Step1 --> Step2[Activity: summarizeWithLLM]
    Step2 --> Step3[Activity: createCeramicStream]
    Step3 --> Step4[Activity: upsertToCitus]
    Step4 --> Step5[Activity: generatePreviewURL]
    Step5 --> Step6[Activity: notifyCircleMembers]
    Step6 --> End[Return preview URL to user]
    
    Step2 -.->|Retry on failure| LLM[Local LLM or OpenAI API]
    Step3 -.->|IPFS pin| Ceramic[Ceramic Network]
    Step4 -.->|RLS enforced| Citus[(Citus DB)]
    Step6 -.->|Matrix protocol| Matrix[P2P Chat]
    
    style Temporal fill:#4A90E2
    style Citus fill:#50C878
    style Ceramic fill:#FF6B6B

Why Temporal?

  • Durability: If the LLM API times out, Temporal automatically retries with exponential backoff
  • Observability: Every workflow execution is logged and can be inspected in the Temporal UI
  • Versioning: You can deploy new workflow code without breaking in-flight executions
  • Distributed execution: Temporal workers run on Oracle VMs, home servers, and even mobile devices

Example workflow code (we'll see the full implementation later):

export async function publishCircleWorkflow(
  circleId: string,
  webstudioProjectId: string
): Promise<string> {
  const content = await activities.extractWebstudioContent(webstudioProjectId);
  const summary = await activities.summarizeWithLLM(content);
  const ceramicStreamId = await activities.createCeramicStream(circleId, content);
  await activities.upsertToCitus(circleId, summary, ceramicStreamId);
  const previewURL = await activities.generatePreviewURL(circleId, ceramicStreamId);
  await activities.notifyCircleMembers(circleId, previewURL);
  return previewURL;
}

Diagram 3: Mobile Edge Node Architecture (Single APK)

The most radical part of irl.coop is the mobile edge node: a single Android app that turns your phone into a full participant in the distributed system.

    subgraph Phone["Android Phone (irl.coop Node App)"]
        subgraph UI["User Interface Layer"]

        end
        
        subgraph Services["Service Layer"]

        end
        
        subgraph Storage["Storage Layer"]
            SQLite[(SQLite Shards)]
            Keystore[Android Keystore<br/>Lit PKP Keys]
            Cache[Local Cache]
        end
        
        Discovery --> ConsulAgent
        Dashboard --> SQLite
        Chat --> MatrixClient
        Settings --> ConsulAgent
        
        ConsulAgent --> |Service tags:<br/>circle_id, capabilities| Consul[Consul Cluster]
        TemporalWorker --> |Poll for tasks| Temporal[Temporal Server]
        MatrixClient --> |P2P sync| Matrix[Matrix Network]
        SyncService --> |Pull/push changes| CitusCoord[Citus Coordinator]
        
        SyncService --> SQLite
        TemporalWorker --> SQLite
    end
    
    Consul -.->|Discover other nodes| OtherPhones[Other Mobile Nodes]
    
    style Phone fill:#E8F5E9
    style SQLite fill:#4CAF50
    style Keystore fill:#FF9800

How it works:

  1. Circle Discovery: When you open the app, the Consul agent queries the service mesh for available circles. Circles are registered as Consul services with tags like circle_id=BakeryCoop, type=cooperative, location=winthrop-ma.

  2. Dynamic Shard Loading: You can join up to 5 active circles at a time. When you join, the Citus Sync Service downloads that circle's shard (typically 10-50MB) as a SQLite database. Inactive circles are archived to free up space.

  3. Temporal Worker: The phone registers as a Temporal worker with specific task queues (e.g., bakery-coop-tasks). When a workflow needs to run a task for the BakeryCoop, it can execute on any member's phone.

  4. P2P Chat: Instead of a centralized chat server, irl.coop uses Matrix's P2P mode. Your phone syncs messages directly with other circle members via WireGuard tunnels.

  5. Offline-First: All reads hit the local SQLite database. Writes are queued and synced when connectivity returns. The app feels instant even on a flaky connection.

The single APK dream: One app, infinite circles. You download "irl.coop" from the Play Store, and it becomes your universal interface for every cooperative, community group, or project you're part of.

  • Redis → Citus: Custom module injects session context as PostgreSQL settings for RLS
  • Temporal → Citus: Workflows read/write to distributed tables with automatic retries
  • Consul → HAProxy: Service discovery drives dynamic load balancer configuration
  • WireGuard → Matrix: P2P chat tunnels use the VPN mesh for NAT traversal

90-Day Implementation Roadmap

This is the actual plan for building irl.coop from scratch. By Day 90, you'll have 100 circles running across 10 phones with zero infrastructure cost.

Week 1-2: Core Infrastructure (Oracle Free Tier)

Goal: Get the control plane and coordination layer running on Oracle's free tier.

Oracle provides 4 OCPU and 24GB RAM for free, forever. We'll use two VM.Standard.A1.Flex instances:

# Instance 1: Coordinator + Temporal + Redis
# 2 OCPU, 12GB RAM, 100GB storage

# Instance 2: Citus Worker + Consul + HAProxy
# 2 OCPU, 12GB RAM, 100GB storage

Setup commands:

# SSH into Oracle instance
ssh ubuntu@<oracle-ip>

# Clone irl.coop infrastructure repo
git clone https://github.com/rbpollock/irl-coop-monorepo
cd infrastructure

# One-command deploy
docker-compose up -d

# Verify services
docker ps
# Should see: consul, redis-sentinel (3 containers), temporal, citus-coordinator

The docker-compose.yml handles:

  • Consul cluster (3 agents for quorum)
  • Redis Sentinel (3 nodes for high availability)
  • Temporal server + UI
  • Citus coordinator
  • HAProxy with Consul template for dynamic config

Week 3-4: Citus + Row-Level Security

Goal: Distribute tables by circle_id and enforce RLS policies.

Create the core schema:

-- Enable Citus extension
CREATE EXTENSION citus;

-- Distributed tables
CREATE TABLE circles (
    circle_id TEXT PRIMARY KEY,
    name TEXT NOT NULL,
    created_at TIMESTAMPTZ DEFAULT NOW()
);

CREATE TABLE circle_members (
    circle_id TEXT REFERENCES circles(circle_id),
    user_id TEXT NOT NULL,
    role TEXT DEFAULT 'member',
    joined_at TIMESTAMPTZ DEFAULT NOW(),
    PRIMARY KEY (circle_id, user_id)
);

CREATE TABLE posts (
    post_id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    circle_id TEXT REFERENCES circles(circle_id),
    author_id TEXT NOT NULL,
    content TEXT,
    created_at TIMESTAMPTZ DEFAULT NOW()
);

-- Distribute by circle_id
SELECT create_distributed_table('circles', 'circle_id');
SELECT create_distributed_table('circle_members', 'circle_id');
SELECT create_distributed_table('posts', 'circle_id');

-- Enable RLS
ALTER TABLE posts ENABLE ROW LEVEL SECURITY;

-- RLS policy: users can only see posts in their circles
CREATE POLICY circle_member_posts ON posts
    FOR ALL
    USING (
        circle_id = current_setting('app.circle_id', true)
        AND current_setting('app.user_id', true) IN (
            SELECT user_id FROM circle_members 
            WHERE circle_id = posts.circle_id
        )
    );

Add the home server and Oracle worker #2:

# On home server
SELECT citus_add_node('home.irl.coop.local', 5432);

# On Oracle instance #2
SELECT citus_add_node('oracle-worker-2.irl.coop.cloud', 5432);

# Verify workers
SELECT * FROM citus_get_active_worker_nodes();

Week 5-6: Temporal Workflows

Goal: Implement the three core workflows.

Install Temporal TypeScript SDK:

npm install @temporalio/client @temporalio/worker @temporalio/workflow

Deploy the publishCircleWorkflow (full code in next section).

Week 7-8: Mobile Edge Node MVP

Goal: Ship the first version of the Android app.

The app includes:

  • Circle discovery UI (queries Consul)
  • SQLite sync service (pulls shards from Citus)
  • Temporal worker (polls for tasks)
  • Matrix P2P chat

Tech stack:

  • Kotlin + Jetpack Compose for UI
  • Ktor for HTTP client
  • SQLDelight for SQLite
  • Consul HTTP API for service discovery

Week 9-10: Circle Actions (42 Total)

Goal: Implement the 12 core actions and 30 extended actions.

Core 12:

  1. Invite member
  2. Publish content
  3. Send chat message
  4. Create task
  5. Vote on proposal
  6. Transfer funds
  7. List product
  8. Purchase product
  9. Schedule event
  10. Check in to event
  11. Update profile
  12. Leave circle

Each action is a Temporal workflow with activities for validation, execution, and notification.

Week 11-12: Scale to 100 Circles

Goal: Stress test with 100 circles across 10 phones.

Challenges:

  • Shard rotation: Phones can't hold 100 shards. Implement LRU eviction (keep 5 active, archive the rest).
  • Failover: What happens when a phone goes offline? Ensure Oracle workers have replicas.
  • Circle agent provisioning: Use Oracle API to auto-create VMs for high-traffic circles.

Day 90 deliverable: A video demo showing:

  1. Creating a new circle (BakeryCoop) on Phone #1
  2. Inviting a member from Phone #2
  3. Publishing a Webstudio site
  4. Executing a cross-circle trade (pottery for bread)
  5. All of this working offline, then syncing when back online

Code Samples: The Implementation Details

Here are six critical code samples that make irl.coop work. These are production-ready snippets you can use as starting points.

1. Citus Table Distribution + RLS Policies (SQL)

This is the complete schema for circle data with RLS enforcement:

-- Enable Citus extension
CREATE EXTENSION IF NOT EXISTS citus;

-- Distributed tables
CREATE TABLE circles (
    circle_id TEXT PRIMARY KEY,
    name TEXT NOT NULL,
    description TEXT,
    circle_type TEXT DEFAULT 'cooperative',
    location TEXT,
    created_at TIMESTAMPTZ DEFAULT NOW(),
    updated_at TIMESTAMPTZ DEFAULT NOW()
);

CREATE TABLE circle_members (
    circle_id TEXT REFERENCES circles(circle_id) ON DELETE CASCADE,
    user_id TEXT NOT NULL,
    role TEXT DEFAULT 'member',
    permissions JSONB DEFAULT '{}',
    joined_at TIMESTAMPTZ DEFAULT NOW(),
    PRIMARY KEY (circle_id, user_id)
);

CREATE TABLE posts (
    post_id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    circle_id TEXT REFERENCES circles(circle_id) ON DELETE CASCADE,
    author_id TEXT NOT NULL,
    content TEXT,
    ceramic_stream_id TEXT,
    created_at TIMESTAMPTZ DEFAULT NOW(),
    updated_at TIMESTAMPTZ DEFAULT NOW()
);

CREATE TABLE transactions (
    tx_id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    from_circle_id TEXT REFERENCES circles(circle_id),
    to_circle_id TEXT REFERENCES circles(circle_id),
    from_user_id TEXT NOT NULL,
    to_user_id TEXT NOT NULL,
    amount DECIMAL(10, 2),
    currency TEXT DEFAULT 'USD',
    status TEXT DEFAULT 'pending',
    created_at TIMESTAMPTZ DEFAULT NOW()
);

-- Distribute all tables by circle_id
SELECT create_distributed_table('circles', 'circle_id');
SELECT create_distributed_table('circle_members', 'circle_id');
SELECT create_distributed_table('posts', 'circle_id');
SELECT create_distributed_table('transactions', 'from_circle_id');

-- Enable Row-Level Security
ALTER TABLE circles ENABLE ROW LEVEL SECURITY;
ALTER TABLE circle_members ENABLE ROW LEVEL SECURITY;
ALTER TABLE posts ENABLE ROW LEVEL SECURITY;
ALTER TABLE transactions ENABLE ROW LEVEL SECURITY;

-- RLS Policies: Users can only access circles they're members of
CREATE POLICY member_circles ON circles
    FOR ALL
    USING (
        circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
    );

CREATE POLICY member_circle_members ON circle_members
    FOR ALL
    USING (
        circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
    );

CREATE POLICY member_posts ON posts
    FOR SELECT
    USING (
        circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
    );

CREATE POLICY author_posts ON posts
    FOR INSERT
    WITH CHECK (
        author_id = current_setting('app.user_id', true)
        AND circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
    );

-- Cross-circle transactions: users can see transactions involving their circles
CREATE POLICY member_transactions ON transactions
    FOR ALL
    USING (
        from_circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
        OR to_circle_id IN (
            SELECT circle_id FROM circle_members 
            WHERE user_id = current_setting('app.user_id', true)
        )
    );

2. Temporal TypeScript Workflow (publishCircleWorkflow)

This workflow orchestrates publishing content from Webstudio to a circle:

// workflows/publishCircle.ts
import { proxyActivities } from '@temporalio/workflow';
import type * as activities from '../activities';

const { 
  extractWebstudioContent,
  summarizeWithLLM,
  createCeramicStream,
  upsertToCitus,
  generatePreviewURL,
  notifyCircleMembers 
} = proxyActivities<typeof activities>({
  startToCloseTimeout: '5 minutes',
  retry: {
    initialInterval: '1s',
    maximumInterval: '30s',
    backoffCoefficient: 2,
    maximumAttempts: 3,

3. Redis C Module (irl.coop.RLS.CONTEXT)

This custom Redis module stores and retrieves RLS context for Citus queries:

// irl.coop_rls.c
#include "redismodule.h"
#include <string.h>

// irl.coop.RLS.CONTEXT SET <session_id> <user_id> <circle_id>
int irl.coopRLSContext_Set(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {

    }
    
    RedisModule_AutoMemory(ctx);
    
    const char *session_id = RedisModule_StringPtrLen(argv[1], NULL);
    RedisModuleString *hash_key = RedisModule_CreateStringPrintf(ctx, "rls:%s", session_id);
    RedisModuleKey *key = RedisModule_OpenKey(ctx, hash_key, REDISMODULE_READ);

    return REDISMODULE_OK;
}

4. Kotlin Mobile Citus Worker (SQLite Sync)

This Android service syncs SQLite shards with the Citus coordinator:

            for (circle in activeCircles) {
                syncCircleShard(circle.circleId)
            }
            
            Result.success()

        if (localChanges.isNotEmpty()) {
            httpClient.post("https://coordinator.irl.coop.coop/api/sync/$circleId") {
                header("Authorization", "Bearer ${getSessionToken()}")
                setBody(localChanges)

5. Lit PKP Session → Redis → RLS Flow (TypeScript)

This shows how authentication flows from Lit PKP to Redis to Citus RLS:

// auth/litPKP.ts
import { LitNodeClient } from '@lit-protocol/lit-node-client';
import { AuthSig, SessionSigs } from '@lit-protocol/types';
import Redis from 'ioredis';
import { v4 as uuidv4 } from 'uuid';

const litClient = new LitNodeClient({ litNetwork: 'cayenne' });
const redis = new Redis(process.env.REDIS_URL);

export async function authenticateWithLitPKP(
  authSig: AuthSig,
  pkpPublicKey: string
): Promise<string> {
  
  // Connect to Lit network
  await litClient.connect();
  
  // Get PKP session signatures
  const sessionSigs = await litClient.getSessionSigs({
    chain: 'ethereum',
    resourceAbilityRequests: [
      {
        resource: { resource: '*', resourcePrefix: 'lit-pkp' },
        ability: 'pkp-signing',
      },
    ],
    authNeededCallback: async () => authSig,
  });
  
  // Derive user ID from PKP public key
  const userId = `pkp:${pkpPublicKey}`;
  
  // Query user's circle memberships from Citus
  const circles = await getUserCircles(userId);
  
  // Create session in Redis
  const sessionId = uuidv4();
  const primaryCircleId = circles[0]?.circle_id || null;
  
  // Use custom Redis module to set RLS context
  await redis.call(
    'irl.coop.RLS.CONTEXT.SET',
    sessionId,
    userId,
    primaryCircleId
  );
  
  // Store session metadata
  await redis.hset(`session:${sessionId}`, {
    user_id: userId,
    pkp_public_key: pkpPublicKey,
    circles: JSON.stringify(circles.map(c => c.circle_id)),
    created_at: Date.now(),
  });
  
  await redis.expire(`session:${sessionId}`, 86400); // 24 hours
  
  return sessionId;
}

export async function setCircleContext(
  sessionId: string,
  circleId: string
): Promise<void> {
  // Verify user is a member of this circle
  const sessionData = await redis.hgetall(`session:${sessionId}`);
  const circles = JSON.parse(sessionData.circles || '[]');
  
  if (!circles.includes(circleId)) {
    throw new Error('User is not a member of this circle');
  }
  
  // Update RLS context
  await redis.call(
    'irl.coop.RLS.CONTEXT.SET',
    sessionId,
    sessionData.user_id,
    circleId
  );
}

// Middleware for Express/Fastify
export async function rlsMiddleware(req, res, next) {
  const sessionId = req.headers['x-session-id'];
  
  if (!sessionId) {
    return res.status(401).json({ error: 'No session ID' });
  }
  
  // Get RLS context from Redis
  const [userId, circleId] = await redis.call(
    'irl.coop.RLS.CONTEXT.GET',
    sessionId
  );
  
  if (!userId) {
    return res.status(401).json({ error: 'Invalid session' });
  }
  
  // Inject into PostgreSQL connection
  req.pgClient = await pgPool.connect();
  await req.pgClient.query(`SET app.user_id = '${userId}'`);
  await req.pgClient.query(`SET app.circle_id = '${circleId}'`);
  
  next();
}

6. Consul + HAProxy Service Discovery (HCL + Config)

This shows how Consul service tags drive HAProxy routing:

# consul/services/bakery-coop.hcl
service {
  name = "circle"
  id = "bakery-coop"
  tags = [
    "circle_id=BakeryCoop",
    "type=cooperative",
    "location=winthrop-ma",
    "members=12",
    "primary_worker=phone-sarah-pixel7"
  ]
  port = 5432
  
  check {
    id = "circle-health"
    name = "Circle Shard Health"
    http = "http://phone-sarah-pixel7.irl.coop.local:8080/health"
    interval = "30s"
    timeout = "5s"
  }
  
  meta = {
    shard_size_mb = "45"
    last_activity = "2024-01-15T10:30:00Z"
    worker_type = "mobile"
  }
}
# haproxy/haproxy.cfg.tmpl (Consul Template)
global
    maxconn 4096

defaults
    mode tcp
    timeout connect 5s
    timeout client 30s
    timeout server 30s

# Dynamic backend for each circle
{{- range services }}
  {{- if .Tags | contains "circle_id" }}
backend circle_{{ .Name }}
    balance leastconn
    {{- range service .Name }}
    server {{ .Node }} {{ .Address }}:{{ .Port }} check
    {{- end }}
  {{- end }}
{{- end }}

# Frontend router
frontend citus_router
    bind *:5432
    mode tcp
    
    # Route based on PostgreSQL database name (= circle_id)
    {{- range services }}
      {{- if .Tags | contains "circle_id" }}
        {{- $circleId := index (.Tags | split "=" ) 1 }}
    acl is_{{ .Name }} req.payload(0,0),pgsql_dbname -i {{ $circleId }}
    use_backend circle_{{ .Name }} if is_{{ .Name }}
      {{- end }}
    {{- end }}

These code samples show the core mechanics of irl.coop. The beauty is that they all work together: Lit PKP authenticates the user, Redis stores the session context, Citus enforces RLS, Temporal orchestrates workflows, and mobile devices sync via SQLite.

Cost Breakdown: $0 Forever

One of the most compelling aspects of irl.coop is the economics. By leveraging free tiers and member-owned devices, we achieve zero recurring infrastructure cost while supporting 1000+ circles.

Oracle Free Tier (Forever Free)

Oracle Cloud provides the most generous free tier in the industry:

  • 2x VM.Standard.A1.Flex instances
    • 4 OCPU total (ARM-based, equivalent to ~8 x86 cores)
    • 24GB RAM total
    • 200GB block storage
    • 10TB outbound data transfer per month
    • Cost: $0/month, forever

Our allocation:

  • Instance 1: Citus Coordinator + Temporal + Redis Sentinel (2 OCPU, 12GB RAM)
  • Instance 2: Citus Worker + Consul + HAProxy (2 OCPU, 12GB RAM)

This handles:

  • 100 circles with moderate activity
  • 1000 concurrent users
  • 10M database queries/day
  • Workflow orchestration for all circles

Home Server (Existing Hardware)

Many irl.coop operators already have a home server or NAS:

  • Typical setup: Old desktop PC, Raspberry Pi 4, or Synology NAS
  • Specs: 4GB+ RAM, 500GB+ storage
  • Power cost: ~$5-10/month (already running for other purposes)
  • irl.coop marginal cost: $0 (uses spare capacity)

Purpose:

  • Citus worker node for personal circles
  • Local backup of critical data
  • WireGuard VPN endpoint

Mobile Devices (100% Decentralized)

The revolutionary part: every member contributes their phone as infrastructure.

  • Storage per circle: 10-50MB (SQLite shard)
  • Compute: Background sync every 15 minutes (~1% battery impact)
  • Network: ~10MB/day for active circles
  • Cost to member: $0 (negligible impact on existing phone usage)

At scale:

  • 100 circles × 10 members each = 1000 phones
  • Each phone holds 5 active circle shards
  • Total distributed storage: 50GB-250GB across the network
  • Total compute capacity: 1000 Temporal workers

Total Cost Analysis

ComponentMonthly CostSupports
Oracle Free Tier$0100 circles, coordination layer
Home Server$0 (marginal)Personal circles, backup
Mobile Devices (1000 phones)$0 (member-owned)All circle data, distributed compute
Cloudflare DNS$0 (free tier)Global DNS, DDoS protection
Total$0/month1000+ circles, unlimited members

Compare to traditional SaaS:

  • Slack: $8/user/month × 1000 users = $8,000/month
  • Notion: $10/user/month × 1000 users = $10,000/month
  • AWS/GCP equivalent infrastructure: $2,000-5,000/month

irl.coop advantage: $18,000-23,000/month saved, or $216,000-276,000/year.

The Cooperative Economics

This cost structure enables a fundamentally different business model:

  1. No venture capital needed: Zero infrastructure cost means no burn rate
  2. Member ownership: Circles can pay a small fee ($5-10/month) to fund development, not infrastructure
  3. Infinite scale: Each new member adds capacity, not cost
  4. Resilience: No single point of failure means no catastrophic cost spikes

The irl.coop cooperative can focus 100% of revenue on:

  • Developer salaries
  • Feature development
  • Member support
  • Community building

Not on AWS bills.

Future: Infinite Scale and the Decentralized Web

irl.coop is just the beginning. Here's where this architecture leads.

Circle Agents: Self-Provisioning Infrastructure

Right now, circles rely on the shared Oracle Free Tier and member phones. But what if a circle grows to 1000 members and needs dedicated infrastructure?

Enter circle agents: autonomous programs that provision their own infrastructure using the circle's treasury.

// Circle agent workflow (runs on Temporal)
export async function provisionCircleInfrastructure(circleId: string) {
  const circleStats = await getCircleStats(circleId);
  
  if (circleStats.members > 500 && circleStats.monthlyRevenue > 100) {
    // Circle can afford its own infrastructure
    const vm = await oracleAPI.createVM({
      shape: 'VM.Standard.E4.Flex',
      ocpus: 2,
      memoryGB: 16,
      paymentSource: circleStats.treasuryWallet,
    });
    
    await deployCircleWorker(vm, circleId);
    await updateConsulService(circleId, { primaryWorker: vm.hostname });
    
    // Notify circle members
    await notifyCircle(circleId, `Your circle now has dedicated infrastructure! 🎉`);
  }
}

The circle becomes self-sovereign: it owns its infrastructure, pays for it from its own treasury, and can migrate to any cloud provider (or back to member phones) at will.

Cross-Circle Token Economies

Circles don't exist in isolation. The BakeryCoop sells bread to the CeramicsTeam. The CeramicsTeam sells pottery to the BakeryCoop. These transactions create a local economy.

irl.coop enables this with:

  1. Circle tokens: Each circle can issue its own token (e.g., $BREAD, $POTTERY)
  2. Escrow workflows: Temporal orchestrates trustless trades between circles
  3. Reputation systems: Successful trades build cross-circle trust
  4. Marketplace discovery: Consul tags enable "find all circles selling pottery in Winthrop, MA"

Example cross-circle trade:

export async function escrowTradeWorkflow(
  fromCircle: string,
  toCircle: string,
  fromAsset: Asset,
  toAsset: Asset
) {
  // Lock both assets in escrow
  await lockAsset(fromCircle, fromAsset);
  await lockAsset(toCircle, toAsset);
  
  // Both circles must approve
  const fromApproval = await waitForApproval(fromCircle, 'majority');
  const toApproval = await waitForApproval(toCircle, 'majority');
  
  if (fromApproval && toApproval) {
    // Execute atomic swap
    await transferAsset(fromAsset, toCircle);
    await transferAsset(toAsset, fromCircle);
    
    // Update reputation
    await updateReputation(fromCircle, toCircle, 'positive');
  } else {
    // Release escrow
    await unlockAsset(fromCircle, fromAsset);
    await unlockAsset(toCircle, toAsset);
  }
}

This creates a mesh economy: circles trading with each other, building trust, and creating value—all without centralized platforms taking a cut.

Global P2P Mesh: No Central Coordinators

The current irl.coop architecture still has a central Citus coordinator (running on Oracle Free Tier). But what if we could eliminate that too?

The vision: Every mobile node is a peer in a global mesh. There is no "coordinator"—just a network of equals.

Technologies to get there:

  • CRDTs (Conflict-Free Replicated Data Types): Replace PostgreSQL with Automerge or Yjs for automatic conflict resolution
  • Gossip protocols: Nodes sync directly with each other, no central server
  • DHT (Distributed Hash Table): Discover circles and members via Kademlia or similar
  • Blockchain anchoring: Periodically anchor circle state to Ethereum/Polygon for tamper-proof history

The end state: irl.coop becomes a protocol, not a platform. Anyone can run a node, join circles, and participate in the mesh. No company, no servers, no single point of failure.

Just humans cooperating.

Call to Action: Build the Decentralized Future

irl.coop is not vaporware. The architecture described in this post is real and buildable today. Every technology mentioned—Citus, Temporal, Lit PKP, Consul, WireGuard, Matrix—is production-ready open source.

Here's how to get started:

1. Run the Stack Locally

Clone the irl.coop infrastructure repo and spin up the entire stack on your laptop:

git clone https://github.com/rbpollock/irl-coop-monorepo
cd infrastructure
docker-compose up -d

In 5 minutes, you'll have:

2. Create Your First Circle

Use the irl.coop CLI to create a circle:

npm install -g @irl.coop/cli
irl.coop circle create BakeryCoop --type cooperative --location "Winthrop, MA"
irl.coop circle invite sarah@example.com --circle BakeryCoop

3. Deploy to Oracle Free Tier

Follow the 90-day roadmap (Week 1-2) to deploy to Oracle Cloud:

irl.coop deploy oracle --instances 2 --region us-ashburn-1

The CLI handles:

  • VM provisioning
  • Docker deployment
  • Consul cluster setup
  • DNS configuration

4. Join the irl.coop Cooperative

irl.coop itself is a circle. We're building this platform cooperatively, with member ownership and democratic governance.

Join us:

Contribute:

  • Developers: Help build the mobile app, Temporal workflows, or Citus modules
  • Designers: Create the UI/UX for circle discovery and management
  • Writers: Document the architecture, write tutorials, create content
  • Operators: Run infrastructure, support circles, manage deployments

5. Start a Circle in Your Community

The real magic happens when you use irl.coop for something real:

  • Neighborhood co-op: Manage shared resources (tools, vehicles, space)
  • Artist collective: Sell work, share studio space, collaborate on projects
  • Mutual aid network: Coordinate support, track needs, distribute resources
  • Local business: Run a bakery, pottery studio, or farm cooperatively

All on infrastructure that costs us $0/month.

But circles are not meant to stay static. They grow and change. They merge and split. They evolve and adapt. They federate together to form larger circles while maintaining their autonomy.


The future of cooperation is decentralized, mobile-first, and member-owned.

The tools are here. The architecture is proven. The economics are sustainable.

Now it's time to build.

Run this stack on your phone. Join the BakeryCoop. Build the decentralized future.

Let's weave a new web—together.
