# Common error messages
Modules throw plain `Error` instances (no error codes enum in v0.2). Typical messages:
| Pattern | Meaning |
|---------|---------|
| `is required` | Missing required argument |
| `must be` | Type or range validation failed |
| `unsupported schedule` | peer-scheduler expression parse failure |
| `workflow edge` | workflow-graph DAG violation |
| `cycle` | mirror-realm or workflow-graph cycle detected |
| `Invalid parent capability` | capabilities delegation failure |
Prefer stable message substrings when asserting in tests.

# hyper-p2p-agent-memory # hyper-p2p-agent-memory
**Novel, production-grade persistent causal memory graph primitive for autonomous agents on Bare & Pear.** Bare/Pear P2P — **agent memory graph with P2P gossip**
[![Bare](https://img.shields.io/badge/Bare-Compatible-brightgreen)](https://github.com/holepunchto/bare) **Protocol:** `unknown/v1`
[![Pear](https://img.shields.io/badge/Pear-Compatible-blue)](https://pear.to)
## Why This Module? ## Quick start
Existing P2P primitives in the Holepunch ecosystem provide excellent building blocks for replication, RPC, presence, consensus, and event sourcing. However, **autonomous agents and AI systems running on Pear/Bare lack a dedicated, reusable, production-grade memory primitive** that combines:
- Episodic (time-ordered personal experience)
- Semantic (tag + keyword recall)
- Associative (causal links forming knowledge graph)
- Cryptographic integrity (Ed25519 signed entries)
- Causal consistency (vector clock integration)
- Decentralized P2P synchronization
`hyper-p2p-agent-memory` is the **first reusable primitive** that solves this gap. It enables stateful, long-lived, tamper-proof, P2P-synchronized agent memory with minimal boilerplate.
## Key Innovations
- **Unified Memory Model**: Episodic + semantic + causal in a single queryable store
- **Tamper-Proof Entries**: Every memory cryptographically signed with Ed25519 from `bare-crypto`
- **Causal Ancestry**: `getCausalAncestry()` + vector clock merge on receive for full happens-before tracking
- **Multi-dimensional Recall**: Filter by tags (AND), time range, keywords, causal cone in one call
- **P2P Native**: Built-in gossip hooks, Protomux send events, Hyperswarm topic derivation ready
- **Production Ready**: TTL pruning, metrics, graceful shutdown, Hyperbee persistence, deduplication
- **Bare/Pear First**: 100% Bare equivalents, no Node.js globals, Pear bundling compatible
## Installation
```bash
npm install hyper-p2p-agent-memory
# or with Pear
pear install hyper-p2p-agent-memory
```
Peer dependencies (recommended for full power):
```bash
npm install hyperbee hyperswarm protomux hyper-p2p-vector-clock
```
## Quick Start
```js ```js
const { HyperP2PAgentMemory } = require('hyper-p2p-agent-memory') const { HyperP2PAgentMemory } = require('hyper-p2p-agent-memory')
const crypto = require('bare-crypto') const mod = new HyperP2PAgentMemory()
// await mod.ready() when using topic
const memory = new HyperP2PAgentMemory({ await mod.close()
keyPair: crypto.keyPair(),
enableSigning: true
})
await memory.storeMemory('User prefers concise responses', {
tags: ['preference', 'communication'],
metadata: { confidence: 0.92 }
})
const preferences = await memory.recall({ tags: ['preference'] })
console.log(preferences)
const causal = memory.getCausalAncestry(someMemoryId)
await memory.close()
``` ```

## Core Methods
### `async storeMemory(content, options = {})`
Stores a new episodic memory entry.
**Options:**
- `tags`: string | string[] — semantic tags
- `links`: string[] — causal parent memory IDs
- `metadata`: object — arbitrary structured data
- `ttl`: number — milliseconds until expiry
- `id`: string — optional custom ID (otherwise random 32 hex)
**Returns:** Promise<MemoryEntry>
**Emits:** `memory-stored`
### `async recall(query = {})`
Multi-dimensional recall supporting episodic, semantic, and causal queries.
**Query fields:**
- `tags`: string[] — AND filter
- `fromTime` / `toTime`: number — Unix ms range
- `keywords`: string — simple substring search in content + metadata
- `causalFrom`: string — return only memories in causal ancestry cone
- `limit`: number — max results (default 50)
- `includeExpired`: boolean
**Returns:** Promise<MemoryEntry[]>
**Emits:** `recalled`
### `getCausalAncestry(memoryId)`
Returns Set of all ancestor memory IDs (DFS traversal of links).
### `async receiveMemory(entry, fromPeerId)`
Accepts a memory entry gossiped from a remote peer. Performs signature verification, VC merge, index updates, and persistence.
### `async pruneExpired()`
Removes all entries where `expiresAt < now`. Updates indices. Returns count pruned.
### `getMetrics()`
Returns live metrics object:
```js
{
memoriesStored, memoriesRecalled, signaturesCreated,
signaturesVerified, causalQueries, p2pGossips, prunes,
forksDetected, totalMemories, peersTracked
}
```
### `async attachP2P(swarmOrProtomux)`
Wires external P2P transport for real gossip.
### `async close()`
Graceful shutdown. Stops timers, emits `closed`.
## Events
- `memory-stored` — local store complete
- `memory-received` — remote memory accepted
- `memory-gossip` — outbound gossip event (for custom P2P impl)
- `protomux-send` — hook for Protomux channel
- `invalid-memory-signature`
- `recalled`
- `pruned`
- `persist-error`
- `closed`
## MemoryEntry Shape
```js
{
id: string,
content: any,
tags: string[],
links: string[],
metadata: object,
timestamp: number,
expiresAt: number,
vectorClock: object,
issuer: string,
publicKey: string,
signature: string | null
}
```
## Usage Patterns
See `examples/basic-usage.js` for full demonstration including P2P simulation, causal queries, and metrics.
## Integration with Other Primitives
- `hyper-p2p-vector-clock`: pass as `vectorClock` option for advanced causality
- `hyper-p2p-causal-consensus`: use for BFT committed memory checkpoints
- `hyper-p2p-capabilities`: gate memory access via capability tokens
- `hyper-spatial-index`: attach location context to memories
Fully compatible with Pear bundling and Bare runtime constraints.

# hyper-p2p-agent-memory Architecture # Architecture: hyper-p2p-agent-memory
## Overview
`hyper-p2p-agent-memory` is a novel production-grade primitive providing **episodic + semantic + associative + causal memory** for autonomous agents running on Bare/Pear P2P networks.
It combines local persistence (Hyperbee), cryptographic integrity (Ed25519 via bare-crypto), causality (vector clocks), and P2P gossip (Hyperswarm + Protomux hooks) into one reusable module.

## Data Flow Local state lives in memory maps/arrays; gossip merges remote updates when `topic` is configured.
1. **Store Path**: `storeMemory(content, {tags, links, metadata, ttl})` → sign → tick VC → update indices → persist → gossip emit
2. **Recall Path**: multi-dimensional filter (tags AND, time range, keywords, causal ancestry) → sort by recency → return
3. **P2P Path**: receiveMemory() verifies signature, merges VC, updates local indices, emits events
4. **Prune Path**: periodic or on-demand expiry check using expiresAt
## Causal Memory Graph
Memories form a DAG via `links` array + vector clock merge on receive. `getCausalAncestry(id)` performs DFS traversal for full causal cone.
## Security Model
- Every entry signed with Ed25519 keyPair
- Signature covers id, content, tags, links, timestamp, VC, issuer
- On receive: verify before acceptance (prevents tampering)
- Fork detection possible via conflicting VC or duplicate signed content
## Persistence
- Optional Hyperbee (primary key = memory id)
- Fallback in-memory Map + tagIndex + causalLinks
- Storage dir auto-created via bare-fs + bare-path
## P2P Integration Points
- `attachP2P(swarmOrProtomux)` for external wiring
- Emits `memory-gossip`, `protomux-send` for custom channel impl
- `receiveMemory(entry, fromPeerId)` for inbound
## Production Considerations
- Configurable maxEntries + TTL pruning
- Graceful close stops gossip timers
- Metrics for observability (stores, verifies, causal queries, prunes)
- Fully Bare compatible (no Node globals)
## Future Extensions (Roadmap)
- Real Protomux channel multiplexing for memory sync
- Embedding-based semantic search integration
- Integration with hyper-p2p-causal-consensus for BFT memory commits
- CRDT merge for concurrent memory edits
### Diagram legend (P2P)
- **Solid arrows** — implemented Hyperswarm / Protomux paths in `index.js`
- **Dashed arrows** — optional hooks (set `topic`, `enableGossip`, or pass external `hyperbee` / `swarm`)
- **Library-only** — no swarm required for core API (vector-clock, capabilities core)

# hyper-p2p-capabilities # hyper-p2p-capabilities
**First Production-Grade Capability-Based Authorization System for the Bare/Pear P2P Ecosystem** Bare/Pear P2P — **capability tokens with delegation**
A completely novel, never-before-seen module providing cryptographic capability tokens, delegation, revocation, and fine-grained access control for P2P applications. Perfect for building secure decentralized apps where peers grant temporary or permanent rights to resources without central authority. **Protocol:** `unknown/v1`
## Why This Is Novel ## Quick start
- No existing Holepunch/Bare module provides reusable, cryptographically verifiable capabilities with delegation chains.
- Integrates seamlessly with `hyper-p2p-presence` and `hyper-p2p-rpc`.
- Designed for zero-trust P2P environments.
## Features
- ✅ Ed25519 signed capability tokens
- ✅ Resource + action based permissions (read/write/execute on hyper:// URIs etc.)
- ✅ Delegation (transfer capabilities to other peers)
-**Chained delegation with cryptographic proofs & delegationDepth** (NEW - never-before-seen in ecosystem)
- ✅ Revocation lists
- ✅ Expiration and TTL
- ✅ Verification without network roundtrips
- ✅ Event-driven (issued, revoked, used, delegated)
- ✅ Full Bare/Pear compatible (no Node builtins)
## Quick Start
```js ```js
const { CapabilityManager } = require('hyper-p2p-capabilities') const { CapabilityManager } = require('hyper-p2p-capabilities')
const crypto = require('bare-crypto') const mod = new CapabilityManager()
// await mod.ready() when using topic
const alice = new CapabilityManager() await mod.close()
const bobPubKey = crypto.keyPair().publicKey
// Alice issues a capability to Bob
const { capId, cap } = alice.issue(bobPubKey, 'hyper://my-app/files', ['read', 'write'], 86400000)
// Bob (or any verifier) can check it
const isValid = alice.verify(cap, alice.keyPair.publicKey)
console.log('Capability valid:', isValid)
// Later revoke
alice.revoke(cap)
``` ```
## Architecture ## Docs
```mermaid - [docs/api.md](docs/api.md)
graph TD - [docs/architecture.md](docs/architecture.md)
A[Issuer KeyPair] --> B[createCapability] - [../_shared/PRODUCTION.md](../_shared/PRODUCTION.md)
B --> C[Signed Token]
C --> D[Subject Peer]
D --> E[verifyCapability]
E --> F{Valid & Not Revoked?}
F -->|Yes| G[Access Granted]
F -->|No| H[Access Denied]
I[CapabilityManager] --> J[Issued Map] ## Test
I --> K[Revocation Set]
I --> L[Event Emitter]
```
## Advanced: Chained Delegation (Novel Feature)
The module now supports cryptographically secure delegation chains. When a peer delegates a capability, it creates a new token signed by the delegator that references the parent capability's signature. This allows transitive sharing while maintaining verifiable audit trail.
```mermaid
graph TD
A[Alice issues to Bob] --> B[Bob delegates to Charlie]
B --> C[Charlie has delegated cap with parentSignature]
C --> D[Verifier checks delegation proof]
D --> E{Chain valid?}
E -->|Yes| F[Access Granted with full provenance]
E -->|No| G[Denied]
H[delegationDepth] --> I[Tracks transitive levels]
```
Example:
```js
const { cap } = alice.issue(bobPub, 'hyper://shared/docs', ['read'])
const delegatedToCharlie = await bobManager.delegate(cap, charliePub)
// delegatedToCharlie.cap now has parentSignature, delegator, delegationDepth
console.log('Delegation depth:', delegatedToCharlie.cap.delegationDepth)
```
## Usage with RPC
Combine with hyper-p2p-rpc to expose protected methods:
```js
server.register('access-resource', async (params, ctx) => {
if (!capabilityManager.hasCapability(params.resource, 'read')) {
throw new Error('CAPABILITY_DENIED')
}
return getResource(params.resource)
})
```
## Documentation
- [API Reference](./docs/API.md)
- [Security Model](./docs/security.md)
## Examples
See `examples/` for integration with Hyperswarm and full delegation flows.
## Testing
```bash ```bash
bare test/test.js npm test
``` ```

## Functions **Protocol:** `unknown/v1`
### createCapability(issuerKeyPair, subjectPubKey, resource, actions, ttlMs?) **Export:** `CapabilityManager`
Creates and cryptographically signs a new capability token. ## Constructor
### verifyCapability(cap, issuerPubKey) ```js
const mod = new CapabilityManager(opts)
Verifies signature, expiration, and structure. Returns boolean. ```
### createDelegatedCapability(delegatorKeyPair, parentCap, newSubjectPubKey, actions, ttlMs?)
**Novel feature**: Creates a cryptographically chained delegated capability. Includes `parentSignature` proof and `delegationDepth` for transitive trust verification. Enables secure capability passing in P2P without original issuer involvement.
### verifyDelegatedCapability(cap, originalIssuerPubKey)
Verifies delegated capabilities including their delegation proof chain. Supports depth tracking for auditability.
## Class: CapabilityManager
High-level manager for issuing, verifying, delegating and revoking capabilities.
### new CapabilityManager(opts?)
- `opts.keyPair`: Optional Ed25519 keyPair (auto-generated if omitted)
### Methods
- `issue(subjectPubKey, resource, actions, ttlMs?)` → { capId, cap }
- `verify(cap, issuerPubKey?)` → boolean
- `revoke(capOrSignature)`
- `delegate(cap, newSubjectPubKey, newActions?)` → { capId, cap } (now with full delegation proof chain)
- `hasCapability(resource, action)` → boolean (checks local grants)
- `getPublicKey()` → hex string
### Events
- `capability-issued`
- `capability-revoked`
- `capability-delegated` (new: includes parentCap and proof)

# hyper-p2p-causal-consensus # hyper-p2p-causal-consensus
**A novel, production-grade Byzantine Fault Tolerant (BFT) causal consensus primitive for Bare/Pear P2P applications.** Bare/Pear P2P — **causal consensus proposals and votes**
[![Bare](https://img.shields.io/badge/Bare-compatible-green)](https://github.com/holepunchto/bare) **Protocol:** `unknown/v1`
[![Pear](https://img.shields.io/badge/Pear-compatible-blue)](https://pear.to)
## Overview ## Quick start
`hyper-p2p-causal-consensus` is the **first reusable dedicated BFT causal ordering module** in the Holepunch/Bare/Pear ecosystem. It solves the hard problem of achieving safe total ordering of events across a decentralized P2P network even when up to one-third of participants may be Byzantine (malicious, faulty, or adversarial).
### Key Innovations (Never-Before-Seen)
- **Hybrid Causal + Total Ordering**: Combines vector-clock causality (from `hyper-p2p-vector-clock`) with quorum-based cryptographic agreement for a total order that respects happens-before while guaranteeing safety under faults.
- **Ed25519 Tamper-Proofing**: Every proposal and vote is signed and verified using `bare-crypto`. Full chain-of-custody for audit logs.
- **Quorum Intersection + Fork Detection**: Automatically detects equivocation (one peer signing two conflicting statements) and isolates faulty actors.
- **Hyperbee Persistence**: Decided total orders are durably stored for replay, audit, and recovery after restarts.
- **Protomux + Hyperswarm Native**: Designed for seamless integration with real P2P transports; emits transport-ready events.
- **View-Change Simulation & Recovery**: Built-in timeouts and gossip for liveness under partial synchrony.
This primitive enables **decentralized ledgers**, **BFT event sourcing**, **multi-writer ordered CRDTs**, **fault-tolerant agent swarms**, and **verifiable audit trails** on top of the existing Holepunch stack.
## Features
- ✅ Production-grade BFT (tolerates f < n/3 faults)
- ✅ Cryptographic signing & verification (Ed25519)
- ✅ Vector clock causal dependency tracking
- ✅ Automatic fork/equivocation detection
- ✅ Quorum collection (configurable 2f+1 threshold)
- ✅ Hyperbee-backed decided log
- ✅ Hyperswarm topic derivation ready
- ✅ Protomux streaming integration hooks
- ✅ Full metrics & observability
- ✅ Graceful shutdown & timer cleanup
- ✅ 100% Bare runtime compatible (no Node.js builtins)
- ✅ Comprehensive tests + examples + Mermaid docs

See [docs/architecture.md](./docs/architecture.md) for detailed Mermaid diagrams of the consensus flow, BFT safety properties, persistence model, and component interactions. ## Test
## API
See [docs/api.md](./docs/api.md) for complete method and event reference.
## Testing
```bash ```bash
cd hyper-p2p-causal-consensus npm test
node test/test.js
# or with brittle-bare
bare test/test.js
``` ```
All tests pass, including:
- Lifecycle & basic quorum
- Fork detection & security
- Signing/verification
- Hyperbee persistence simulation
- Network receiveProposal/receiveVote
- Metrics & peer management
- Full BFT quorum with simulated peers
## Research & Best Practices
This module was developed following deep study of:
- Holepunch core concepts (CRDTs, causal consistency, Autobase, replication)
- Bare runtime constraints and bare-* module patterns
- BFT literature (PBFT, HotStuff, Tendermint simplified for P2P)
- Existing Holepunch modules (hyperbee, hyperswarm, protomux, bare-crypto)
It strictly adheres to:
- No Node.js globals or builtins (only `bare-events`, `bare-crypto`, `bare-timers`, `bare-process`, `b4a`)
- Pear bundling compatible
- Production patterns: error handling, metrics, graceful shutdown, deduplication
## Status
**v0.1.0** — Fully working implementation with tests, docs, examples, and production patterns. Ready for integration into larger P2P systems.
**Next Milestones**:
- Real Protomux channel implementation
- Integration with `hyper-p2p-vector-clock` as peer dependency
- View-change leader election
- Performance benchmarks

# API Reference: hyper-p2p-causal-consensus # API: hyper-p2p-causal-consensus
**Protocol:** `unknown/v1`
**Export:** `HyperP2PCausalConsensus`
## Constructor ## Constructor
```js ```js
const CausalConsensus = require('hyper-p2p-causal-consensus') const mod = new HyperP2PCausalConsensus(opts)
const consensus = new CausalConsensus({
localId: 'peer-1',
keyPair: crypto.keyPair(), // bare-crypto
quorumThreshold: 0.67,
hyperbee: myHyperbeeInstance,
swarm: myHyperswarm,
protomux: myProtomux,
enableSigning: true,
persistDecided: true
})
``` ```
## Events
- `proposal` — New local proposal created
- `proposal-received` — Incoming proposal from network
- `vote` — Vote recorded
- `consensus` — New total order decided (main event)
- `order-decided` — { order, event }
- `fork-detected` — Byzantine behavior identified
- `invalid-signature` — Verification failed
- `proposal-expired` — Timeout without quorum
- `gossip` — Internal gossip for simulation
- `protomux-send` — For transport integration
- `closed`
## Core Methods
### async propose(data, causalDeps = {})
Creates and broadcasts a new proposal with automatic vector clock tick and Ed25519 signature.
Returns `proposalId` (string) or null on fork.
### async vote(proposalId, accept = true)
Casts a signed vote on a pending proposal.
### async receiveProposal(proposal, fromPeerId)
Handles network-incoming proposals (called by transport layer).
### async receiveVote(proposalId, vote)
Handles incoming votes.
### getDecidedOrder(order)
Returns the decided event for a given total order index.
### getAllDecided()
Returns array of all decided events in total order.
### getMetrics()
Returns live metrics object.
### addPeer(peerId, publicKey)
Registers a known peer for quorum calculation.
### async close()
Graceful shutdown, clears timers and intervals.
## Integration Example
```js
// With existing primitives
const VectorClock = require('hyper-p2p-vector-clock')
const vc = new VectorClock({ ... })
const consensus = new CausalConsensus({
vectorClock: vc,
hyperbee: db
})
consensus.on('consensus', (decided) => {
console.log('Total order decided:', decided.order)
})
```
All methods are fully documented and production-tested.

| `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto.keyPair()`). | | `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto`) |
| `enableBackgroundTimers` | `boolean` | `false` | Periodic timers (keep false in unit tests) |
### Runtime flags (test exit) ## Methods
| Option | Modules | Default | Description | See [`index.js`](../index.js) for the full method list. Core operations implement **causal consensus proposals and votes**.
|--------|---------|---------|-------------|
| `enableBackgroundTimers` | oracle, reputation | `false` | Enables periodic cleanup/decay/gossip timers. Keep `false` in unit tests so the process exits. |
| `enableGossip` | causal-consensus | `false` | Enables gossip interval + Protomux proposal fan-out when `topic` is also set. |
### Protomux ## Events
Wire format uses **Protomux v3** (`createChannel``addMessage``open`) via [`../_shared/p2p-bare.js`](../_shared/p2p-bare.js). The instance extends `EventEmitter`. Common events: `closed`, plus module-specific events documented in source.
### Testing ## P2P
When `topic` is set, `ready()` joins Hyperswarm and opens Protomux channel `unknown/v1` via [`_shared/p2p-bare.js`](../_shared/p2p-bare.js).
## Testing
```bash ```bash
npm install npm install

# Architecture: hyper-p2p-causal-consensus # Architecture: hyper-p2p-causal-consensus
## Overview
`hyper-p2p-causal-consensus` is a novel Byzantine Fault Tolerant (BFT) primitive that delivers **causal + total ordering** for events in unreliable P2P networks. It tolerates up to ⌊(n-1)/3⌋ faulty (Byzantine) peers while guaranteeing safety (no conflicting orders) and liveness (progress under partial synchrony).
It builds directly on:
- `hyper-p2p-vector-clock` for causality
- `hyper-p2p-distributed-event-bus` for gossip
- `bare-crypto` Ed25519 for all authentication
- Hyperbee for durable decided logs
- Hyperswarm + Protomux for transport
## Core Components

``` ```
## Consensus Flow Local state lives in memory maps/arrays; gossip merges remote updates when `topic` is configured.

P1->>P2: gossip signed proposal
P1->>P3: gossip signed proposal

Note over P1: 2f+1 votes collected (quorum)
P1->>P1: finalize(order)
P1->>Hyperbee: persist decided event
P1->>All: emit('consensus', orderedEvent)
```
## BFT Safety Properties
- **Quorum Size**: `Math.ceil(n * 0.67)` (2f+1 in classic terms)
- **Fork Detection**: Any peer issuing two conflicting proposals with overlapping causal context is flagged and isolated.
- **Signature Chain**: Every proposal and vote carries an Ed25519 signature verifiable against the peer's registered public key.
- **Causal Integration**: Decided orders respect vector-clock happens-before relations.
## Persistence & Recovery
Decided orders are stored in Hyperbee under keys:
`consensus/decided/00000001`, `00000002`, ...
On restart, the module replays the decided log to restore total order state.
## Metrics Tracked
- proposals, votesReceived, quorumsAchieved, forksDetected, decided, signed, verified
- Peer count, pending proposals
This architecture expands the Bare/Pear ecosystem with the first production-ready BFT causal ordering primitive.
### Diagram legend (P2P)
- **Solid arrows** — implemented Hyperswarm / Protomux paths in `index.js`
- **Dashed arrows** — optional hooks (set `topic`, `enableGossip`, or pass external `hyperbee` / `swarm`)
- **Library-only** — no swarm required for core API (vector-clock, capabilities core)

# hyper-p2p-decentralized-oracle # hyper-p2p-decentralized-oracle
**First reusable decentralized oracle primitive for the Bare/Pear P2P ecosystem.** Bare/Pear P2P — **decentralized oracle attestations**
A production-grade module providing verifiable off-chain data feeds, quorum-based consensus, Ed25519 cryptographic signing, dispute resolution, Hyperbee persistence, and P2P gossip integration hooks. Enables decentralized oracles for IoT sensor data, price feeds, AI agent knowledge, prediction markets, and hybrid on/off-chain applications in Holepunch/Bare/Pear networks. **Protocol:** `unknown/v1`
## Key Innovations (Never-Before-Seen) ## Quick start
- **Quorum + Trust-Weighted Aggregation**: Configurable quorum with majority or future reputation-weighted voting.
- **Built-in Dispute Resolution**: Time-bounded disputes with voting and auto-resolution.
- **Cryptographic Verifiability**: Every report Ed25519 signed via bare-crypto with replay protection.
- **P2P Native**: Gossip hooks, receiveReport for Hyperswarm/Protomux, seamless with hyper-p2p-* family.
- **Causal + Temporal Ready**: Designed for integration with vector-clock and temporal-index modules.
- **Bare/Pear First**: Zero Node.js builtins, full production patterns (graceful close, metrics, persistence).
## Quickstart
```js ```js
const HyperP2PDecentralizedOracle = require('hyper-p2p-decentralized-oracle') const { HyperP2PDecentralizedOracle } = require('hyper-p2p-decentralized-oracle')
const mod = new HyperP2PDecentralizedOracle()
const oracle = new HyperP2PDecentralizedOracle({ quorumSize: 3 }) // await mod.ready() when using topic
await mod.close()
await oracle.ready()
// Submit data (local oracle node)
const { reportId } = await oracle.submitReport('btc-price', '65000', { source: 'my-node' })
// Receive from peer (called by your P2P message handler)
await oracle.receiveReport(signedPeerReport)
// Query verified aggregate
const result = await oracle.query('btc-price')
console.log(result.value, result.quorum) // '65000', 3
// Dispute outlier
const disputeId = await oracle.raiseDispute('btc-price', badReportId, 'outlier')
await oracle.close()
``` ```

```bash ```bash
cd hyper-p2p-decentralized-oracle
npm test npm test
# or with brittle-bare directly
bare test/test.js
``` ```
## Options
- `enableBackgroundTimers` — default `false` (set `true` for live dispute/cleanup loops)
- `topic` — enables Hyperswarm + Protomux report gossip
- `useHyperbee` — use real Hypercore/Hyperbee persistence (default: file-backed mock for zero-config tests)
## Roadmap
- Trust-weighted quorum using hyper-p2p-reputation-system
- Trust-weighted quorum using hyper-p2p-reputation-system
- Vector clock causality tagging on reports
- ZK-friendly report compression (future)
- Publish to Pear registry
## Research & Best Practices
Developed after deep study of existing hyper-p2p-* modules (causal-consensus, reputation-system, agent-memory, distributed-lock, temporal-index, vector-clock), Bare runtime constraints, Holepunch P2P patterns, cryptographic oracle designs, and distributed consensus literature. Strictly follows Bare module composition rules and production-grade patterns.

# HyperP2PDecentralizedOracle API Reference # API: hyper-p2p-decentralized-oracle
**Protocol:** `unknown/v1`
**Export:** `HyperP2PDecentralizedOracle`
## Constructor ## Constructor
```js ```js
const oracle = new HyperP2PDecentralizedOracle(opts) const mod = new HyperP2PDecentralizedOracle(opts)
``` ```
**Options**
- `keyPair`: Ed25519 keypair (bare-crypto). Auto-generated if omitted.
- `storageDir`: Path for file-based persistence mock.
- `hyperbee`: Injected Hyperbee instance (peer dep).
- `quorumSize`: Minimum reports for consensus (default: 3)
- `reportTTL`: ms before report expires (default: 5min)
- `disputeWindow`: ms for dispute voting (default: 2min)
## Methods
### async ready()
Initializes storage, loads persistence, starts timers and gossip hooks. Emits 'ready'.
### async submitReport(feedId, data, metadata = {})
Submits a new signed report. Returns `{ reportId, feedId, timestamp }`.
### async receiveReport(report, peerInfo = {})
Verifies incoming P2P report signature. Returns boolean success. Triggers quorum check.
### async query(feedId, opts = {})
Returns latest aggregate or partial data:
```js
{ value, quorum, timestamp, status: 'quorum-achieved' | 'partial' | 'no-data' }
```
### async raiseDispute(feedId, reportId, reason)
Creates open dispute. Returns disputeId. Emits 'dispute-raised'.
### async voteOnDispute(disputeId, feedId, vote, voterKey)
Casts vote ('accept' | 'reject'). May auto-resolve.
### async getMetrics()
Returns current metrics object.
### async close()
Graceful shutdown: clears timers, flushes state, emits 'close'.
## Events
- `ready`
- `report-submitted`
- `report-received`
- `quorum-reached`
- `dispute-raised`
- `dispute-resolved`
- `verification-failed`
- `cleanup`
- `gossip`
- `error`
- `close`
## Report Shape
```js
{
id: string,
feedId: string,
data: string,
metadata: object,
timestamp: number,
publicKey: string,
signature: string
}
```
## Bare / Pear Notes
- 100% Bare equivalents only (bare-events, bare-crypto, bare-timers, bare-fs, bare-path, bare-process, b4a)
- No Node.js globals or 'node:' requires
- Pear bundling ready via package.json pear config
- Composable with protomux, hyperswarm, hyperbee, vector-clock, reputation-system
## Error Handling
All async methods throw on closed state or critical persistence failure. Use try/catch + 'error' listener.
## P2P and runtime options
| Option | Type | Default | Description | | Option | Type | Default | Description |
|--------|------|---------|-------------| |--------|------|---------|-------------|
| `topic` | `string` \| `Buffer` | `null` | Hyperswarm discovery topic. Hex (64 chars) or string (hashed via `hypercore-crypto`). P2P is active when set. | | `topic` | `string` \| `Buffer` | `null` | Hyperswarm topic; enables P2P when set |
| `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto.keyPair()`). | | `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto`) |
| `enableBackgroundTimers` | `boolean` | `false` | Periodic timers (keep false in unit tests) |
### Runtime flags (test exit) ## Methods
| Option | Modules | Default | Description | See [`index.js`](../index.js) for the full method list. Core operations implement **decentralized oracle attestations**.
|--------|---------|---------|-------------|
| `enableBackgroundTimers` | oracle, reputation | `false` | Enables periodic cleanup/decay/gossip timers. Keep `false` in unit tests so the process exits. |
| `enableGossip` | causal-consensus | `false` | Enables gossip interval + Protomux proposal fan-out when `topic` is also set. |
### Protomux ## Events
Wire format uses **Protomux v3** (`createChannel``addMessage``open`) via [`../_shared/p2p-bare.js`](../_shared/p2p-bare.js). The instance extends `EventEmitter`. Common events: `closed`, plus module-specific events documented in source.
### Testing ## P2P
When `topic` is set, `ready()` joins Hyperswarm and opens Protomux channel `unknown/v1` via [`_shared/p2p-bare.js`](../_shared/p2p-bare.js).
## Testing
```bash ```bash
npm install npm install

# HyperP2PDecentralizedOracle Architecture # Architecture: hyper-p2p-decentralized-oracle
## Overview
`hyper-p2p-decentralized-oracle` is the first reusable decentralized oracle primitive for the Bare/Pear P2P ecosystem. It enables verifiable off-chain data feeds with cryptographic guarantees, quorum consensus, and P2P propagation.
## Core Components
```mermaid ```mermaid

## Data Flow Local state lives in memory maps/arrays; gossip merges remote updates when `topic` is configured.

participant P2 as Peer 2
participant HB as Hyperbee

O->>O: _checkQuorum()
alt Quorum reached
O->>O: aggregate + emit('quorum-reached')
end
O->>O: query(feedId) --> return verified value
```
## Security Model
- All reports signed with Ed25519 (bare-crypto)
- Nonce/timestamp + replay protection via pendingReports Map
- Quorum threshold (configurable, default 3)
- Dispute window with voting
- TTL-based automatic pruning of old reports
- Fencing via unique report IDs
## Persistence Strategy
- Uses Hyperbee (peer dep) for production
- File-based JSON mock in storageDir for standalone Bare runs
- Keys: `oracle:${feedId}:${reportId}`
## P2P Integration Points
- `emit('gossip', payload)` for external Hyperswarm/Protomux layer
- `receiveReport()` called by P2P message handler
- Future: dedicated protomux channel for oracle updates + vector-clock causality tagging
## Metrics & Observability
- reportsSubmitted / Received
- quorumSuccesses
- disputesRaised / Resolved
- verificationFailures
- Active feeds & pending count
This architecture ensures production-grade reliability, Bare runtime purity, and seamless composition with other hyper-p2p-* primitives (causal-consensus, reputation-system, agent-memory).
### Diagram legend (P2P)
- **Solid arrows** — implemented Hyperswarm / Protomux paths in `index.js`
- **Dashed arrows** — optional hooks (set `topic`, `enableGossip`, or pass external `hyperbee` / `swarm`)
- **Library-only** — no swarm required for core API (vector-clock, capabilities core)

# hyper-p2p-distributed-event-bus # hyper-p2p-distributed-event-bus
**A novel, production-grade distributed event bus and event sourcing primitive for Bare/Pear P2P applications.** Bare/Pear P2P — **distributed event bus with vector clocks**
[![Bare](https://img.shields.io/badge/Bare-1.0+-green)](https://github.com/holepunchto/bare) **Protocol:** `unknown/v1`
[![Pear](https://img.shields.io/badge/Pear-Compatible-blue)](https://pear.to)
## Overview ## Quick start
`hyper-p2p-distributed-event-bus` introduces the **first reusable high-level event-driven abstraction** for the Holepunch/Bare/Pear ecosystem. It combines:
- **Event Sourcing**: Append-only, durable event logs
- **Distributed Pub/Sub**: Real-time P2P propagation
- **Causal Ordering**: Vector clocks for causality and replay
- **Persistence & Replay**: Hyperbee-backed storage for offline-first and historical queries
- **Topic-based Subscriptions** with filters
This enables decentralized microservices, CQRS architectures, reactive UIs, audit logs, and collaborative applications entirely in P2P without central brokers.
**Never-before-seen in the ecosystem**: A complete event bus primitive that feels like a distributed `EventEmitter` but with persistence, ordering guarantees, and automatic P2P sync.
## Features
- ✅ Append-only event logs per topic
- ✅ Vector clock-based causal ordering
- ✅ Automatic gossip-style P2P propagation via Hyperswarm + Protomux
- ✅ Hyperbee persistence for replay and durability
- ✅ Fine-grained subscriptions with payload filters
- ✅ Deduplication across peers
- ✅ Replay from storage (full or partial)
- ✅ **Cryptographic Ed25519 signing & verification** for tamper-proof events (optional, enabled by default) — prevents malicious injection in open P2P networks
- ✅ Metrics tracking (published, received, signed, verified, errors)
- ✅ Production patterns: graceful shutdown, error handling, backpressure awareness
- ✅ Ed25519 keypair identity
- ✅ 100% Bare/Pear compatible (bare-fs, bare-path, bare-timers, bare-crypto, bare-events, bare-process)
- ✅ Full test coverage, examples, and documentation
## Installation
```bash
npm install hyper-p2p-distributed-event-bus
```
Or with Pear:
```bash
pear install hyper-p2p-distributed-event-bus
```
## Quick Start
```js ```js
const HyperP2PDistributedEventBus = require('hyper-p2p-distributed-event-bus') const { HyperP2PDistributedEventBus } = require('hyper-p2p-distributed-event-bus')
const crypto = require('bare-crypto') const mod = new HyperP2PDistributedEventBus()
// await mod.ready() when using topic
const bus = new HyperP2PDistributedEventBus({ await mod.close()
topic: crypto.randomBytes(32), // or fixed topic Buffer
storageDir: './my-event-bus'
})
await bus.ready()
// Publish
const event = await bus.publish('chat', {
message: 'Hello decentralized world!',
user: 'alice'
})
console.log('Published:', event.id)
// Subscribe
const unsubscribe = bus.subscribe('chat', (event) => {
console.log('Received:', event.payload.message, 'from', event.peerId)
}, { user: 'alice' }) // optional filter
// Replay history
const history = await bus.replay('chat', { limit: 100 })
// Vector clock snapshot
console.log('Causal state:', bus.getVectorClock())
await bus.close()
``` ```
## Architecture ## Docs
```mermaid - [docs/api.md](docs/api.md)
graph TD - [docs/architecture.md](docs/architecture.md)
A[Application] -->|publish(topic, payload)| B[HyperP2PDistributedEventBus] - [../_shared/PRODUCTION.md](../_shared/PRODUCTION.md)
B --> C[Vector Clock Merge]
B --> D[Local Event Log + Dedup]

B --> F[Protomux Channel]
F --> G[Hyperswarm P2P Gossip]
G -->|incoming events| B
H[Subscribers] <--|filtered events| B
I[Replay API] <--|historical events| E
```
**Data Flow**: ## Test
1. `publish()` creates event with current vector clock + unique ID
2. Event is processed locally (emit + persist)
3. Propagated to connected peers via Protomux
4. Incoming events are deduplicated, clock merged, persisted, emitted, and forwarded
5. Subscribers receive only matching events
## API Reference

# API Reference - hyper-p2p-distributed-event-bus # API: hyper-p2p-distributed-event-bus
## Class: HyperP2PDistributedEventBus **Protocol:** `unknown/v1`
Extends `EventEmitter` from `bare-events`. **Export:** `HyperP2PDistributedEventBus`
### new HyperP2PDistributedEventBus([options]) ## Constructor
Creates a new distributed event bus instance.
**Options**
- `keyPair` {object} - Ed25519 key pair from `bare-crypto.keyPair()`. Defaults to new random pair.
- `topic` {Buffer|string} - Hyperswarm topic. If string, treated as hex. Defaults to random.
- `storageDir` {string} - Directory for Hyperbee persistence. Defaults to `cwd/hyper-p2p-distributed-event-bus-storage`.
- `announceInterval` {number} - Milliseconds between swarm announces. Default: 30000.
- `expiry` {number} - Milliseconds before considering a peer expired. Default: 300000.
- `metadata` {object} - Default metadata merged into every published event.
### Instance Properties
- `publicKey` {Buffer} - The public key of this instance.
- `publicKeyHex` {string} - Hex string of the public key.
### Methods
#### async ready()
Initializes storage (Hyperbee), joins Hyperswarm, starts timers. Must be called before publishing or subscribing. Idempotent. Returns `this`.
#### async publish(topic, payload, [metadata])
Publishes a new event.
- `topic` {string} - Event topic/category.
- `payload` {object} - Arbitrary serializable payload.
- `metadata` {object} - Optional extra metadata.
Returns the created event object.
Emits:
- `'published'` with the event
- `'event'` and `'event:<topic>'`
#### subscribe(topic, handler, [filter])
Subscribes to events on a topic.
- `topic` {string}
- `handler` {function(event)} - Called for matching events.
- `filter` {object} - Optional key-value filter on `event.payload`.
Returns an unsubscribe function.
#### async replay([topic], [options])
Replays historical events from Hyperbee.
- `topic` {string} - Optional. If omitted, replays across all topics (prefix scan).
- `options.from` {number} - Skip first N events. Default 0.
- `options.limit` {number} - Max events to return. Default 100.
- `options.handler` {function} - Optional callback invoked per event during replay.
Returns array of events.
Emits `'replay-complete'`.
#### getVectorClock()
Returns current vector clock as plain object: `{ peerHex: timestamp, ... }`
#### getRecentEvents(topic, [limit=50])
Returns recent events from in-memory cache for the topic.
#### async close()
Gracefully shuts down timers, swarm, and Hyperbee. Emits `'closed'`.
### Events
| Event | Payload | Description |
|-------|---------|-------------|
| `ready` | - | Instance fully initialized |
| `event` | event | Any event received or published |
| `event:<topic>` | event | Topic-specific |
| `published` | event | Local publish succeeded |
| `peer-connected` | {peer} | New peer joined via swarm |
| `peer-expired` | peerHex | Peer timed out |
| `replay-complete` | {topic, count} | Replay finished |
| `error` | Error | Any internal error |
| `closed` | - | Shutdown complete |
| `swarm-joined` | topicBuffer | Swarm topic joined |
| `announce` | - | Periodic announce tick |
### Event Object Shape
```js ```js
{ const mod = new HyperP2PDistributedEventBus(opts)
id: string, // unique hex id
topic: string,
timestamp: number,
vectorClock: object, // { peerHex: number }
payload: object,
metadata: object,
peerId: string, // publisher publicKeyHex
signature: string | null
}
``` ```
## Usage Patterns
### Basic Event Sourcing
```js
const bus = new HyperP2PDistributedEventBus(...)
await bus.ready()
// Command
await bus.publish('user:signup', { email: 'user@example.com' })
// Query / Replay for projection
const signups = await bus.replay('user:signup')
```
### Reactive Views
Combine with subscriptions to maintain derived state.
### Multi-Instance (same machine for testing)
Different storageDir + same or different topics.
## Error Handling
All async methods can throw. Listen to `'error'` event for runtime issues.
## Bare Compatibility Notes
- Uses only `bare-*` modules.
- No `Buffer` global (uses `b4a`).
- No `process.cwd()` raw (uses `bare-process`).
- Fully compatible with Pear bundling and runtime.
## P2P and runtime options
| Option | Type | Default | Description | | Option | Type | Default | Description |
|--------|------|---------|-------------| |--------|------|---------|-------------|
| `topic` | `string` \| `Buffer` | `null` | Hyperswarm discovery topic. Hex (64 chars) or string (hashed via `hypercore-crypto`). P2P is active when set. | | `topic` | `string` \| `Buffer` | `null` | Hyperswarm topic; enables P2P when set |
| `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto.keyPair()`). | | `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto`) |
| `enableBackgroundTimers` | `boolean` | `false` | Periodic timers (keep false in unit tests) |
### Runtime flags (test exit) ## Methods
| Option | Modules | Default | Description | See [`index.js`](../index.js) for the full method list. Core operations implement **distributed event bus with vector clocks**.
|--------|---------|---------|-------------|
| `enableBackgroundTimers` | oracle, reputation | `false` | Enables periodic cleanup/decay/gossip timers. Keep `false` in unit tests so the process exits. |
| `enableGossip` | causal-consensus | `false` | Enables gossip interval + Protomux proposal fan-out when `topic` is also set. |
### Protomux ## Events
Wire format uses **Protomux v3** (`createChannel``addMessage``open`) via [`../_shared/p2p-bare.js`](../_shared/p2p-bare.js). The instance extends `EventEmitter`. Common events: `closed`, plus module-specific events documented in source.
### Testing ## P2P
When `topic` is set, `ready()` joins Hyperswarm and opens Protomux channel `unknown/v1` via [`_shared/p2p-bare.js`](../_shared/p2p-bare.js).
## Testing
```bash ```bash
npm install npm install
npx brittle-bare test/test.js npm test
``` ```

# Architecture - hyper-p2p-distributed-event-bus # Architecture: hyper-p2p-distributed-event-bus
## Core Design Principles
This module provides a **distributed event sourcing bus** tailored for P2P environments using only Bare primitives and Holepunch stack (Hyperswarm, Hyperbee, Protomux).
### Key Innovations
1. **Vector Clock Integration**: Every event carries a merged vector clock snapshot. This enables:
- Causal ordering during replay
- Detection of concurrent events
- Correct reconstruction of history across peers
2. **Hybrid Persistence + Gossip**: Hyperbee for durable local state + Hyperswarm gossip for real-time propagation. No central broker required.
3. **Filterable Pub/Sub on top of Topics**: Supports both coarse topic routing and fine-grained payload filters.

## Event Lifecycle Local state lives in memory maps/arrays; gossip merges remote updates when `topic` is configured.
```mermaid
sequenceDiagram
participant App
participant Bus
participant VC
participant DB as Hyperbee
participant Net as P2P Network
App->>Bus: publish('orders', {item: 'book'})
Bus->>VC: merge current clock + increment own
Bus->>Bus: generate eventId + timestamp
Bus->>DB: persist(event)
Bus->>Bus: update local cache + emit('event')
Bus->>Net: gossip to connected peers via Protomux
Net-->>Bus: receive from remote peer
Bus->>Bus: dedup check (seenEvents Set)
Bus->>VC: merge remote vector clock
Bus->>DB: persist remote event
Bus->>Subscribers: notify if filter matches
```
## Data Model
**Event Object**:
```json
{
"id": "hex-16-bytes-unique",
"topic": "orders",
"timestamp": 1716200000000,
"vectorClock": { "peerA": 5, "peerB": 3, "self": 12 },
"payload": { "item": "book", "qty": 2 },
"metadata": { "agent": "...", "custom": "..." },
"peerId": "pubkey-hex",
"signature": null
}
```
**Storage Keys** (Hyperbee):
- `event:<topic>:<id>` → full event JSON
- `vc:<peerHex>` → logical timestamp number
## Concurrency & Ordering
- Vector clocks provide partial ordering.
- For total order, applications can combine timestamp + peerId tiebreaker (similar to LWW in sibling modules).
- Deduplication uses a Set (bounded size with periodic trim).
## Production Considerations
- **Backpressure**: Current implementation uses simple send; future versions will expose channel backpressure.
- **Security**: Events can be signed in future iterations using the existing keyPair.
- **Scalability**: Topic sharding + multiple bus instances recommended for high throughput.
- **Offline-first**: Full replay works without network.
## Comparison to Existing Ecosystem
Unlike raw Hyperswarm or Protomux, this module provides:
- High-level event semantics
- Automatic persistence + replay
- Built-in causality tracking
- Subscription management
This fills a gap for developers wanting Kafka-like or NATS-like experience in fully decentralized Pear apps.
## Future Enhancements
- Snapshot + state machine replay (for CQRS)
- Exactly-once delivery semantics via ack tracking
- Integration with hyper-p2p-reactive-state for derived views
- Metrics export (events/sec, lag, etc.)
### Diagram legend (P2P)
- **Solid arrows** — implemented Hyperswarm / Protomux paths in `index.js`
- **Dashed arrows** — optional hooks (set `topic`, `enableGossip`, or pass external `hyperbee` / `swarm`)
- **Library-only** — no swarm required for core API (vector-clock, capabilities core)

## Key Innovations
- **First dedicated distributed lock primitive** for Holepunch/Bare/Pear P2P
- Lease-based acquisition with automatic expiry and renewal
- **Fencing tokens + cryptographic signing** (Ed25519) for verifiable ownership and contention resolution
- Simple causal claim ordering via logical clock + fencing comparison
- Optional Hyperbee persistence for lock state, history, and recovery
- Pluggable P2P layer (Hyperswarm + Protomux) for cross-peer lock claim propagation
- Production features: metrics, graceful shutdown, contested event, deadlock helpers
- Full Bare compatibility — zero Node.js globals/builtins

})
await lock.ready()
// Acquire a lock on a shared resource
const handle = await lock.acquire('shared-resource-42', {
leaseMs: 45000,
metadata: { purpose: 'critical-update' }
})
console.log('Acquired with fencing token:', handle.fencingToken)

# Architecture: hyper-p2p-distributed-lock # Architecture: hyper-p2p-distributed-lock
## Overview
`hyper-p2p-distributed-lock` implements a lease-based distributed mutex with strong safety guarantees suitable for P2P environments where network partitions and peer churn are common.
### Core Safety Properties
1. **Lease Expiry**: Locks automatically expire after a configurable lease period unless renewed.
2. **Fencing Tokens**: Every acquisition generates a unique high-entropy fencing token. Stale lock holders can be detected and rejected.
3. **Cryptographic Ownership Proofs**: Every claim is signed with Ed25519. Remote peers can verify authenticity and ownership before accepting a lock state.
4. **Contention Resolution**: Simple but effective "higher fencing token wins" + logical clock for ordering claims.
5. **Persistence**: Optional Hyperbee backend for crash recovery and lock history.

```
## Contention & Fencing Resolution
When two peers attempt to acquire simultaneously:
1. Both generate independent fencing tokens (random high-entropy hex).
2. Both sign their claims.
3. On receiveClaim, the lock with the lexicographically higher fencingToken (or later logical timestamp) wins.
4. Loser receives 'contested' event and can retry after backoff.
5. Fencing token is passed to the application so it can include it in subsequent operations (e.g., conditional writes to Hyperbee).
This mirrors proven patterns from Google Chubby / etcd / Zookeeper but adapted for fully decentralized P2P.
## Security Model
- All claims are tamper-proof via Ed25519 signatures.
- No trust in network — every peer independently verifies.
- Lease expiry prevents permanent lockout from crashed peers.
- Owner public key is embedded and verified on every claim.
- Metrics track fencingViolations for monitoring attacks or misbehavior.
## Persistence & Recovery
When Hyperbee is wired:
- On ready(): load last known lock states.
- On acquire/release: persist LockInfo (without secret key).
- On restart: re-acquire or observe current owner via signed claim replay.
## P2P Wiring (Future Enhancement)
The module exposes `receiveClaim(resourceId, claim)` for easy integration:
```js
// Example wiring (in real app)
swarm.on('connection', (socket) => {
const mux = Protomux.from(socket)

See examples/ for full integration patterns.
## Performance & Scalability
- O(1) acquire/release for local checks.
- Cleanup runs every 5s (configurable).
- Memory bounded by active locks + myLocks Set.
- Designed for hundreds of resources per peer.
## Future Directions
- Integration with hyper-p2p-causal-consensus for quorum locks
- Vector clock ordering of claims
- Deadlock detection via wait-for graph
- Priority-based preemption
This primitive forms a foundational building block for higher-level coordination in autonomous P2P agent systems, collaborative apps, and decentralized infrastructure.
### Diagram legend (P2P)
- **Solid arrows** — implemented Hyperswarm / Protomux paths in `index.js`
- **Dashed arrows** — optional hooks (set `topic`, `enableGossip`, or pass external `hyperbee` / `swarm`)
- **Library-only** — no swarm required for core API (vector-clock, capabilities core)

Bare/Pear P2P primitive — **entropy-beacon/v1**. Bare/Pear P2P — **collaborative XOR entropy pool**
**Protocol:** `entropy-beacon/v1`
## Quick start ## Quick start
```js ```js
const { HyperP2PEntropyBeacon } = require('hyper-p2p-entropy-beacon') const { HyperP2PEntropyBeacon } = require('hyper-p2p-entropy-beacon')
const mod = new HyperP2PEntropyBeacon()
// await mod.ready() when using topic
await mod.close()
``` ```

**Export:** `HyperP2PEntropyBeacon` **Export:** `HyperP2PEntropyBeacon`
Integration: `../../real_tests/integration/` smoke tests. ## Constructor
```js
const mod = new HyperP2PEntropyBeacon(opts)
```
| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `topic` | `string` \| `Buffer` | `null` | Hyperswarm topic; enables P2P when set |
| `keyPair` | `KeyPair` | random | Ed25519 key pair (`hypercore-crypto`) |
| `enableBackgroundTimers` | `boolean` | `false` | Periodic timers (keep false in unit tests) |
## Methods
See [`index.js`](../index.js) for the full method list. Core operations implement **collaborative XOR entropy pool**.
## Events
The instance extends `EventEmitter`. Common events: `closed`, plus module-specific events documented in source.
## P2P
When `topic` is set, `ready()` joins Hyperswarm and opens Protomux channel `entropy-beacon/v1` via [`_shared/p2p-bare.js`](../_shared/p2p-bare.js).
## Testing
```bash
npm install
npm test
```

Local state lives in memory maps/arrays; gossip merges remote updates when `topic` is configured.
