chore: initial commit for v0.0.1
DChain single-node blockchain + React Native messenger client. Core: - PBFT consensus with multi-sig validator admission + equivocation slashing - BadgerDB + schema migration scaffold (CurrentSchemaVersion=0) - libp2p gossipsub (tx/v1, blocks/v1, relay/v1, version/v1) - Native Go contracts (username_registry) alongside WASM (wazero) - WebSocket gateway with topic-based fanout + Ed25519-nonce auth - Relay mailbox with NaCl envelope encryption (X25519 + Ed25519) - Prometheus /metrics, per-IP rate limit, body-size cap Deployment: - Single-node compose (deploy/single/) with Caddy TLS + optional Prometheus - 3-node dev compose (docker-compose.yml) with mocked internet topology - 3-validator prod compose (deploy/prod/) for federation - Auto-update from Gitea via /api/update-check + systemd timer - Build-time version injection (ldflags → node --version) - UI / Swagger toggle flags (DCHAIN_DISABLE_UI, DCHAIN_DISABLE_SWAGGER) Client (client-app/): - Expo / React Native / NativeWind - E2E NaCl encryption, typing indicator, contact requests - Auto-discovery of canonical contracts, chain_id aware, WS reconnect on node switch Documentation: - README.md, CHANGELOG.md, CONTEXT.md - deploy/single/README.md with 6 operator scenarios - deploy/UPDATE_STRATEGY.md with 4-layer forward-compat design - docs/contracts/*.md per contract

|

# internal — только internal — только internal — только
|
||||
# для node1 для node2 для node3
|
||||
#
|
||||
# Правила:
|
||||
# • Ноды общаются только через backbone «internet» по фиксированным IP.
|
||||
# • Каждая dc-сеть изолирована (internal: true) — имитирует приватную
|
||||
# LAN датацентра, недоступную для других нод напрямую.
|
||||
# • P2P bootstrap — через IP backbone-сети, как в реальном интернете.
|
||||
# • Все три ноды — полноценные валидаторы и relay-провайдеры.
|
||||
# PBFT 3-of-3, fault tolerance f=1: сеть работает при падении одной.
