feat(chain): remove channels, add social feed (Phase A of v2.0.0)
Replaces the channel/membership model with a VK/Twitter-style feed:
public posts, follow graph, likes. Views are deliberately off-chain
(counted by the hosting relay, Phase B).
Removed
- EventCreateChannel, EventAddMember
- CreateChannelPayload, AddMemberPayload, ChannelMember
- prefixChannel, prefixChanMember
- chain.Channel(), chain.ChannelMembers()
- node/api_channels.go
- GetChannel, GetChannelMembers on ExplorerQuery
Added
- Events: CREATE_POST, DELETE_POST, FOLLOW, UNFOLLOW, LIKE_POST, UNLIKE_POST
- Payloads: CreatePostPayload, DeletePostPayload, FollowPayload,
UnfollowPayload, LikePostPayload, UnlikePostPayload
- Stored shape: PostRecord (author, size, hash, hosting relay, timestamp,
reply/quote refs, soft-delete flag, fee paid)
- State prefixes: post:, postbyauthor:, follow:, followin:, like:, likecount:
- Queries: Post(), PostsByAuthor(), Following(), Followers(),
LikeCount(), HasLiked()
- Cached like counter via bumpLikeCount helper
Pricing
- BasePostFee = 1000 µT (aligned with MinFee block-validation floor)
- PostByteFee = 1 µT/byte of compressed content
- Total fee credited in full to HostingRelay pub (storage compensation)
- MaxPostSize = 256 KiB
Integrity
- CREATE_POST validates content_hash length (32 B) and size range
- DELETE_POST restricted to post.Author
- Duplicate FOLLOW / LIKE rejected
- reply_to and quote_of mutually exclusive
Tests
- TestFeedCreatePost: post stored, indexed, host credited
- TestFeedInsufficientFee: underpaid post is skipped
- TestFeedFollowUnfollow: follow graph round-trips via forward + inbound indices
- TestFeedLikeUnlike: like toggles with dedup, counter stays accurate
- TestFeedDeletePostByOther: non-author deletion rejected
This is Phase A (chain-layer). Phase B adds the relay feed-mailbox
(post bodies + gossipsub) and HTTP endpoints. Phase C adds the client
Feed tab.

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
