REPRAM

REplicated EPhemeral RAM - Distributed Ephemeral Storage System

A distributed, ephemeral key-value storage network designed for applications requiring high-performance, privacy-preserving data storage with self-expiring capabilities. Client-side AES-256-GCM encryption ensures a zero-trust security model where network nodes cannot access stored data.

Key Features

Privacy-first distributed storage with enterprise-grade security and performance.

Client-Side Encryption

AES-256-GCM encryption occurs on user devices before transmission. Nodes store only encrypted data without access to content.

RAM-Only Storage

Data operates exclusively in RAM with no disk persistence, eliminating forensic data recovery possibilities.

Automatic Expiration

Implements TTL (time-to-live) settings with automatic cleanup of expired data.

Gossip Protocol

Peer-to-peer replication using gRPC-based gossip protocol for distributed data redundancy.

Configurable Quorum

Balance availability and consistency with configurable quorum settings across your node cluster.

Zero-Trust Model

Network nodes cannot interpret or read user data. End-to-end encryption throughout the system.

REST API

Simple HTTP endpoints for storing and retrieving ephemeral data.

MethodEndpointDescription
PUT/data/{key}Store binary data with TTL
GET/data/{key}Retrieve stored data
GET/healthHealth status check
GET/statusDetailed node metrics
GET/metricsPrometheus-compatible metrics
POST/raw/putStore unencrypted strings (open source mode)
GET/raw/get/{key}Retrieve strings (open source mode)

System Architecture

REPRAM comprises three main components working together to provide secure, distributed ephemeral storage.

Open Source Node

MIT-licensed Go server with REST API and in-memory storage. Handles data persistence, replication, and cluster coordination.

Proprietary SDK

Commercial Go library handling client-side encryption and node communication. Provides simple APIs for secure data operations.

Gossip Protocol

gRPC-based replication with bootstrap and quorum mechanisms. Nodes self-organize into hierarchical networks for optimal data distribution.

# Build options
make build         # Main encrypted node
make build-raw     # Open-source unencrypted variant
make build-cluster # Distributed cluster version

# Docker deployment (3-node cluster)
docker-compose up -d

# Nodes available at:
# - localhost:8080
# - localhost:8081
# - localhost:8082

# Store data with TTL (60 seconds)
curl -X PUT http://localhost:8080/data/mykey \
  -H "Content-Type: application/octet-stream" \
  -H "X-TTL: 60" \
  -d "my secret data"

# Retrieve data
curl http://localhost:8080/data/mykey
