epress world protocol (EWP)

The epress world protocol defines how autonomous nodes establish trust, exchange identity, and replicate signed content in epress world.

Protocol Baseline: EWP v1 semantics for node interoperability

Quick Start: Implement EWP

Build a minimal EWP-compatible node in under an hour.

Start Tutorial

Overview: Protocol at a Glance

EWP is the interoperability layer between autonomous nodes. It defines how nodes prove identity, establish relationship state, publish signed content, and synchronize data over time without central coordination.

Identity Plane

Profile and address discovery provide the trust anchor for each node.

Interaction Plane

Follow/unfollow handshakes build and maintain relationship state.

Data Plane

Signed content and replication messages keep timelines consistent.

Core Design Principles

Autonomy

Each node operates independently. No central server or coordinator required. Nodes choose who to follow and what to publish.

Cryptographic Identity

Ethereum wallet addresses serve as persistent identities. EIP-712 signatures prove authorship without on-chain transactions.

Content Integrity

Every signed publication includes a content hash. Content cannot be modified without invalidating the signature.

Replication on Demand

Content replicates to followers on publish. No flooding or broadcast. Nodes pull only what they need.

Timestamp Ordering

Signed timestamps establish publication order. Prevents replay attacks and enables timeline consistency.

HTTP Transport

All protocol operations use standard HTTP. Works through proxies, CDNs, and firewalls without special configuration.
