|
||||
|
||||
## [0.2.0] - 2026-05-20
|
||||
|
||||
### Added
|
||||
- Real Hyperswarm + Protomux v3 wiring via `../_shared/p2p-bare.js` (where applicable)
|
||||
- 2-node integration test under `real_tests/integration/`
|
||||
|
||||
### Changed
|
||||
- Protomux v3: `createChannel` + `addMessage` + `channel.open()`
|
||||
|
||||
## [0.1.1] - 2026-05-20
|
||||
|
||||
### Fixed
|
||||
- Migrated tests from `bare-test` to `brittle` / `brittle-bare`
|
||||
- `hypercore-crypto` for keyPair, sign, verify, hash
|
||||
- `bare-process/global` and `bare-process` v4 imports
|
||||
- Background timers opt-in (`enableBackgroundTimers`, `enableGossip`) for clean test exit
|
||||
<!-- legacy: v0.2.0 -->
|
||||
|
||||
- Production-grade docs, validation, and expanded tests.
|
||||
<!-- legacy: v0.3.0 -->
|
||||
|
||||
- Wave 6: presence-tier API tables, architecture wire section, validation test.
|
||||
|
||||

# hyper-p2p-decentralized-oracle
|
||||
|
||||
Production oracles module: Hyperswarm discovery + Protomux when `topic` is set.
|
||||
|
||||
**Category:** Oracles
|
||||
|
||||
**Composes with:** `hyper-p2p-attestation-chain`, `hyper-p2p-quorum-pool`
|
||||
|
||||
**Protocol:** `hyper-p2p-decentralized-oracle/v1`
|
||||
|
||||
## When to use
|
||||
|
||||
Multi-peer apps that need oracles over a shared Hyperswarm topic.
|
||||
|
||||
## When not to use
|
||||
|
||||
Single-process tools with no P2P topic (use local APIs only or skip `ready()`).
|
||||
|
||||
## Quick start
|
||||
|
||||
```js
|
||||
const { HyperP2PDecentralizedOracle } = require('hyper-p2p-decentralized-oracle')
|
||||
const topic = process.argv[2] // 64-char hex or string
|
||||
const mod = new HyperP2PDecentralizedOracle({ topic, enableBackgroundTimers: false })
|
||||
await mod.ready() // joins swarm when topic set
|
||||
// ... application logic ...
|
||||
await mod.close()
|
||||
```
|
||||
|
||||

## Overview
|
||||
|
||||
Production oracles module: Hyperswarm discovery + Protomux when `topic` is set.

|
||||
```
|
||||
|
||||
| Option | Type | Default | Description |
|
||||
|--------|------|---------|-------------|
|
||||
| `keyPair` | KeyPair | random Ed25519 | keyPair |
|
||||
| `storageDir` | `<cwd>/{module}-storage` | `<cwd>/{module}-storage` | Hypercore/Hyperbee storage root |

|
||||

## Events
|
||||
|
||||
| Event | Payload |
|
||||
|-------|---------|
|
||||
| `cleanup` | timestamp |
|
||||
| `close` | no payload |
|
||||
| `dispute-raised` | payload object |
|
||||
| `dispute-resolved` | status |
|
||||
| `error` | err |
|
||||
| `hyperbee-fallback` | err |
|
||||
| `persistence-loaded` | no payload |
|
||||
| `quorum-reached` | aggregate |
|
||||
| `ready` | no payload |
|
||||
| `report-received` | peer |
|
||||
| `report-submitted` | payload object |
|
||||
| `verification-failed` | reportId, peer |
|
||||
|
||||
## getStats()
|
||||
|
||||
Returns `{ ...this._stats }` — typically `ops`, `errors`, and module-specific counters (`created`, `relays`, `open`, `peers`, etc.).
|
||||
Library-only modules may include `mode: 'local'`.
|
||||
|
||||
## Errors
|
||||
|
||||
Stable message substrings: see [`../_shared/ERROR_CODES.md`](../../_shared/ERROR_CODES.md).
|
||||
|
||||
## P2P
|
||||
|
||||
When `topic` is set, `ready()` joins Hyperswarm and opens Protomux `hyper-p2p-decentralized-oracle/v1`.
|
||||
|
||||

Provides verifiable off-chain data feeds with quorum-based aggregation, Ed25519 signed reports, dispute resolution mechanisms, time-bounded query windows, Hyperbee persistence for feed history and aggregates, P2P gossip hooks via Hyperswarm/Protomux for real-time updates, causal ordering integration via vector clocks, trust-weighted quorum voting, automatic expiry/pruning, event-driven notifications, and rich metrics. Enables hybrid on/off-chain verifiable data oracles for IoT, AI agents, DeFi, prediction markets, and decentralized apps in the Holepunch/Bare/Pear ecosystem.
